Oral surgeons need accurate patient information to ensure they are able to care for patients. In this case study, a patient visits an OMS for a tooth extraction. Three days post-operation, the patient reports increased swelling and swallowing difficulty to the office manager. The office manager labels the symptoms as normal and fails to tell the treating OMS about the patient’s concerns. With increased swelling, the patient presents to a hospital, where an oral surgeon performs intra- and extra-oral I&Ds. After a painful recovery and permanent scars, the patient sues the OMS for malpractice.

Background Facts

V is a generally healthy 32-year-old man who presented to his general dentist with a complaint of pain and mild swelling associated with his lower left first molar, which had previously been treated endodontically and restored with a post and crown. The dentist evaluated the area and found tooth #19 to have a likely vertical fracture, such that it required extraction. Given that the general dentist did not regularly perform extractions, V was referred to Dr. P, an oral and maxillofacial surgeon.

When Dr. P examined V clinically and radiographically, she found what appeared to be a periapical radiolucency on that tooth, adjacent to the soft tissue swelling, and found that there was also a likely fracture of the tooth. Extraction was the suggested treatment, with V agreeing to proceed along that path. Dr. P engaged V in a back-and-forth discussion, and obtained his informed consent, which was memorialized on a document – in which all traditional extraction risks, benefits and alternatives were set forth – signed by both Dr. P and V.

In a very straightforward manner, using only local anesthesia, V’s tooth #19 was extracted, with a small mass of granulomatous tissue, which had been attached to the root, removed in the process. No sutures were required. Dr. P prescribed an NSAID analgesic and an antimicrobial mouth rinse. That evening, the office manager called V, as was usual for all patients who had been surgically treated, and was told that he was doing well.

On the third post-operative day, V called the office and spoke with the office manager again. There was some increased swelling “under the jawline” that was concerning to V. The office manager advised V that this was “nothing unusual,” but that V should keep the office posted. V did just that the following day, describing worsening swelling and the beginnings of some swallowing difficulties. The office manager responded by telling V that she had been working for Dr. P for more than ten years, and this kind of thing happens often, so that it was not anything to be worried about. Neither of the conversations was documented or transmitted to Dr. P.

With the swelling continuing to enlarge downward toward the neck, V presented to a local hospital emergency department, where he was seen by the on-call oral surgeon, who wondered, aloud, why Dr. P had not prescribed antibiotics at the time of infection or seen V when he developed problems. In any event, the hospital oral surgeon took V to the operating room for intra- and extra-oral I&Ds under general anesthesia, followed by a 3-day course of IV antibiotics while still in the hospital, and then oral antibiotics upon discharge. V lost nearly 3 weeks from work, had a painful recovery, and continues to have 2 prominent facial scars from the surgery.

Legal Action

A local attorney, well known to handle malpractice cases, was contacted and then retained by V, to look into pursuing a claim of malpractice against Dr. P. It was never learned whether it was the commentary of the hospital oral surgeon that led V to seek an attorney. The attorney gathered the records from Dr. P, the referring general dentist, and the treating hospital, and sent those, along with a descriptive narrative, to an oral and maxillofacial surgeon who regularly advertises his “expert” services.

The prospective expert identified two potential areas of liability, which might be implicated in causing the injuries claimed: (1) Dr. P failed to prescribe antibiotics at the time of extraction, even though an active infection was clearly present, thereby failing to control the infection and stop it from progressing; and (2) Dr. P’s office manager, a non-professional, offered clinical advice to V, twice, which delayed his treatment to the point that hospitalization and invasive care were needed to control the infection, leading directly to the injuries claimed. The expert advised V’s attorney that the informed consent process was appropriate, and also advised that the use of antibiotics at the time of extraction in a situation like this was a matter of judgment on Dr. P’s part. With philosophies against antibiotic use becoming more prevalent, such a claim would be difficult to prove.

However, the expert maintained a strong opinion that the office manager, Dr. P’s employee, had overstepped her bounds by giving V advice, which allowed the infection to worsen, unabated, until the options of care were limited to exactly what eventually took place. The expert attributed the dispensing of advice by a layperson to an inappropriate office policy on the part of Dr. P, which gave the office manager permission – at least tacitly – to advise patients without consulting with Dr. P.

A lawsuit was filed by V’s attorney, naming both Dr. P and her practice entity as defendants. Once served with the legal papers, she contacted her professional liability carrier, which provided her with defense counsel. After meeting with Dr. P and reviewing all of the relevant records, her counsel enlisted the opinions of another oral and maxillofacial surgery expert, who essentially concurred with the views of V’s expert. Once made aware of her expert’s agreement with V’s expert, Dr. P acknowledged that she had erred in placing no checks on what her office staff was able to transmit to patients. She immediately changed that approach going forward.

Dr. P and her attorney spoke about the possibility of a potential settlement payment to V being made on behalf of the practice entity, which was insured under a separate policy, rather than on her personal behalf. The attorney and insurance carrier staff concluded that this was the type of case that would properly lend itself to such a payment, as Dr. P was not alleged to have performed any negligent actions, with only her lay staff member being so alleged. Under those terms, Dr. P waived her right to withhold consent to settlement, with a settlement agreed to shortly after.

Takeaways

This case study raises a number of issues that are important to an understanding of the malpractice litigation process. The first is that of “judgment calls.” Many states have provisions in their statutes which allow practitioners to exercise their professional judgment, which, if sound, does not subject them to malpractice. Like most aspects of malpractice litigation, the idea of judgment being “sound” is ultimately up to expert interpretation. But in situations like these, where there are legitimate competing views as to proper courses of care, and where the experts on both sides of the issues are fair evaluators, V would have had a very difficult time proving that Dr. P was negligent in her determination that antibiotics were not necessary, despite the fact that V’s infection worsened and required surgical treatment. What matters is the prospective view, and not one with 20/20 hindsight.

Perhaps the most valuable idea to be learned here involves the concept of vicarious liability, meaning that a person/entity (here, Dr. P/her practice) in a “superior legal position” to the actual wrongdoer is responsible for the negligent acts of that wrongdoer. The office manager was an employee who was acting in her capacity as an employee at the time the inappropriate advice was given. And because the office manager’s actual employer in this situation was the practice entity, rather than Dr. P personally, it was the practice entity that was in that “superior legal position,” making it the vicariously liable body. It is for this reason that the settlement was made as against the practice rather than Dr. P. That is an important distinction. In many, if not all, jurisdictions, settlements made on behalf of a doctor must then be reported to certain state and/or national authorities, whereas those made on behalf of practice entities carry no such reporting requirements. Reporting issues aside, it should be clear that MedPro policies will provide coverage in situations like the actions of the office manager here, whether formally an employee of a practice entity or of an individual doctor, and therefore closed out on behalf of either that entity or doctor.

Dr. P’s corrective actions going forward, namely that all clinical advice to patients, or reports of clinical problems by patients, must be transmitted by staff to Dr. P, who will then prescribe the proper action to be taken. Administrative matters, such as billing, insurance filings, and appointments would still be left in the hands of staff members, unless clinical issues crept into those matters. In this office, the change was an involved and sometimes murky set of modifications, but the fruits which emerged improved patient care and decreased the risk of malpractice events and litigation.

Settlement value is often the result of a method that includes both objective and subjective components. In the end, settlement is achieved when there is a meeting of the minds, between the insurance carrier and the patient-plaintiff. It has been said many times by trial lawyers that a good settlement is one in which neither side is too unhappy.

Finally, we address policy coverage for vicarious liability. An oral surgeon should fully evaluate policy provisions for this consideration, to determine whether it exists at all, and if so, whether all employees are covered – including employee oral surgeons, dentists, nurses, etc. – or just those employees who are not professionals. The difference is significant, to say the least, so being fully aware of that aspect of the policy will lead the oral surgeon to a purchase that best fits their needs and best protects them.

Background facts

R was a 61-year-old generally healthy man who had worn maxillary full dentures for years, but was becoming increasingly dissatisfied with them, both functionally and esthetically. His lower arch posed no problems for him: other than a 3-unit fixed bridge on the right and a 4-unit bridge on the left, he had natural teeth in place. In the past, he was a nearly pack-a-day smoker, but he had since overcome that habit. He presented to a multispecialty dental office he had seen advertised locally, seeking to improve the condition of his maxilla.

He initially saw a prosthodontist, who evaluated the mouth and concluded that an implant-supported prosthesis would work well for R. Per office policy, the on-site oral surgeon would handle the implant aspect of treatment, with the patient then returning to the prosthodontist for the restoration. That same day, the OMS, Dr. G, met with R, ordered a CBCT study, reviewed it, and discussed the available options. Because of the paucity of maxillary bone — especially posteriorly — and "low-lying" maxillary sinus cavities, a traditional implant arrangement would not be possible. So, 2 options were available: (1) perform bilateral sinus lifts with bone grafting, allow for an adequate healing period, place 3 implants (potentially) on each side, and then restore the maxilla prosthetically after osseointegration; or (2) do an all-on-4 procedure using the pterygoid bones bilaterally for both posterior implants, place a provisional prosthetic appliance that same day, and later convert to a permanent prosthesis after integration.

The office management encouraged the most time-efficient case completions possible. With that in mind, Dr. G and the prosthodontist discussed the available options, with Dr. G expressing some concern about the radiographically appearing rather thin pterygoids, particularly on the right side. However, the prosthodontist did not want to wait for the entire sinus lift process to play out, and encouraged the OMS to do the all-on-4 approach, despite her stated concerns. Dr. G (reluctantly) agreed, and so did R, after they had a full discussion about the most common risks, benefits, and options, with R signing a consent form.

On the day of treatment, R took the oral sedative prescribed for him by Dr. G, just before leaving home. Dr. G injected local anesthetic solution buccally and palatally across the entire upper jaw. Because she is left-handed, Dr. G began with her preferred side, the left, because access was easier. Referring to the CBCT images, she uneventfully placed 2 implants on the left side, 1 at the approximate site where tooth #11 had been, and 1 angled into the pterygoid: both were clinically stable. She then turned to the right side to place 2 implants before the prosthodontist placed the ready provisional. The implant near the prior site of the upper right canine was smoothly placed. In performing the right pterygoid osteotomy, Dr. G's concern came to fruition, as the bur, which had initially been met with typical bony resistance, suddenly fell into a void, which she presumed to be the pterygopalatine fossa. When she backed out the handpiece, bright red, pulsating blood heavily flowed into the mouth, clouding the entire field.

Her initial approach was to pack the site with gauze strips, which did slow the flow, but the gauze quickly filled with blood and continued to do so despite repeated packing. Dr. G believed that she had pierced into (a branch of) the right maxillary artery. With her being unable to gain hemostatic control, and being in an outpatient setting with an awake patient, she attempted to gain access to the source of the bleed by entering the maxillary sinus through a Caldwell-Luc approach, and then cutting a window through the posterior sinus wall to enter the fossa. But doing so only provided a second outlet of significant bleeding, leading her to conclude that ligating the artery required in-hospital care by a head and neck surgeon. R was transported by ambulance to a nearby medical center, with Dr. G accompanying him to try to maintain site pressure as they travelled. R was emergently taken to the OR, where he was induced and intubated, and where an ENT surgeon unsuccessfully attempted access to the torn vessel endoscopically, ultimately ligating the vessel some 2 hours later by way of a preauricular approach infratemporally. R remained in hospital for a week, and missed work for more than a month, left with a scar and always feeling limitations to his usual exercise routine.

Legal action

R's newly retained attorney obtained all of the relevant dental and medical records, and sent them on to an academic-based OMS for review. That expert passed on his conclusions to the attorney who hired him: that Dr. G succumbed to external pressures and performed a procedure that she knew was concerning and risky, given the specific anatomy presented, and that the preferred set of procedures for this patient would have begun with the sinus lift and graft approach. The attorney also contacted the treating ENT, who was willing to provide his opinion that the bleed and the resultant surgery and after-effects were due to an ill-conceived surgical treatment plan by Dr. G.

Dr. G contacted her malpractice carrier when she provided records to R's attorney, and again when she was served with papers that initiated the lawsuit against her. She had personally been deeply upset by the events, now some months ago, and she told her assigned attorney that she was eager to put this behind her, partly for the personal impact but also because she realized that she had not exercised her best judgment.

Settlement moves began quickly, with an agreement reached before discovery even started. In addition to money, which covered medical costs, physical and emotional distress, and lost income, R made a somewhat unusual request: that Dr. G write an apology and explanation to him, which he felt that he needed to close the chapter. Despite her attorney advising Dr. G against doing so, explaining the potential impacts upon a Board complaint (which never happened) or hospital credentialing, she did as R had asked, because she, too, needed the closure.

Takeaways

Pressures are frequently placed on practitioners, including oral surgeons, from sources as diverse as patients, dental or medical colleagues, and practice supervisors and owners. The reasons for the responses to those pressures are equally diverse, from the need to maintain employment, to conflict aversion, to ego. In the end, though, all that really matters on the legal side of practice are adherence to standards of care and principles of ethics. Perhaps, a safe approach for practitioners to take is that if something simply does not feel right, stay away from it. While that might not always be practical, it can at least be an internal starting point, if not ultimately the end point.

It is the general rule, rather than the exception, that there are most often multiple options/alternatives to overcome dental and surgical problems. Principles of informed consent dictate the requirement to advise patients of, among other things, available alternatives. But that does not mean every alternative, only the viable ones. And if an alternative is not viable for any reason, whether because of patient anatomy, underlying patient medical conditions and social habits, or provider limitations (based upon ability or experience), that alternative falls out of the realm of informed consent. Here, the anatomy of R's right pterygoid and, perhaps (reading between the lines) her own limitations, Dr. G seemingly knew that an all-on-4 plan was not viable for R. Fighting her better judgment was a clear factor in the events and injuries.

All procedures carry risk. It is part and parcel of healthcare delivery, particularly when surgery is involved. Practitioners appropriately take specific risks into account when weighing the potential coming to fruition of those risks against the benefits of doing the procedure. There is no one-size-fits-all formula to use to come to a decision, but instead a subjective process that is individual to every surgeon, considering a host of factors. Many risks come to pass (in the form of injury) in the absence of any negligence, with that concept being a foundation for much of malpractice defense, but when injuries occur because of negligence, that often becomes the very basis for plaintiffs' cases against doctors.

Decisions about settlement versus trial are extremely case-specific, with the insurer, counsel, and all litigants playing significant roles. Practitioners who have "pure consent" policies are permitted, per policy language, to withhold consent to a settlement, in favor of going to trial. But in cases where practitioners do provide their consent to settle, that does not mean that the malpractice carrier must then settle the case, but simply that it may agree to a settlement. Think of it as a permission slip, but not a requirement slip.

Summary of takeaways

External pressures should never outweigh clinical judgment when determining the most appropriate treatment plan.
Not every treatment option is suitable for every patient — anatomy, provider experience, and overall risk must be carefully evaluated before proceeding.
When complications occur, treatment decisions that fall outside the standard of care can increase liability exposure and lead to malpractice claims.

In this real-life case study, oral and maxillofacial surgeons will learn how coding decisions and informed consent gaps can create significant liability risks. Discover why accurate billing, clear patient communication, and thorough consent discussions are essential risk management tools.

Background facts

For Dr. C, an oral and maxillofacial surgeon, extracting teeth was an everyday part of practice. As the only oral surgeon within a 2–3-hour drive, she was a participating provider in a number of dental insurance programs which were more popular within her patient and referral bases.

One such patient, T, was an 18-year-old high school senior who self-presented based upon a network list, with a new complaint of periodic pain associated with the lower right third molar. Despite T being of majority, his mother accompanied him into the treatment room to see Dr. C. Following a clinical examination, a panoramic film was taken and viewed by Dr. C. Tooth #32 was erupted, had incomplete apex formation, but was still in close radiographic proximity to the inferior alveolar canal. Dr. C assessed the pain to be a function of difficulty in cleansing the area, with inflamed gingivae as a result. She suggested, while pointing to the panoramic, extraction, which she said, "shouldn't be too hard,” although it carried a "slight risk of a nerve injury which could leave T's lower lip and chin numb, and rarely be permanent." This conversation was documented with specificity in the chart. T had heard about impacted wisdom teeth from a few friends, so he asked whether his tooth was impacted. Dr. C replied, "No, it is not.” T wanted to think about it, so he left the office with a sample of an oral rinse and instructions as to how to improve his oral hygiene, particularly in that area of the mouth. A month later, the symptoms persisted, so T's mother called the office to schedule an extraction appointment.

Before having local anesthetic injected, T was handed a paper entitled "consent form,” which he and his mother "briefly read.” The document contained a list of potential risks, including a general statement about possible "loss of sensation.” T signed the document prior to the extraction going forward. Dr. C worked on the tooth for nearly an hour, much longer than she had anticipated, cutting out pieces of tooth and trimming away bone using round and fissure burs. T could taste blood, particularly at one point which caused Dr. C to pack gauze in his mouth. The following day, T awoke to find the right half of his lower lip and chin numb, which he did not find surprising, given the warning beforehand, but so was the right half of his tongue, which was a surprise. At post-op visits, Dr. C assured and re-assured T and his mother that feeling would return to normal — it never did.

Separately, T received a bill for Dr. C's services from her billing office, seeking a co-pay for "#32 7240.” The amount was significant, despite Dr. C's advertised plan participation, so T's mother questioned the office manager as to what all of this meant. The response was that, according to the insurance plan's rules, Dr. C was permitted to charge that amount for fully impacted wisdom teeth, as this was. T's mother replied that Dr. C had specifically advised her and her son that the tooth was not impacted, no less fully so. The office manager spoke with Dr. C, but the answer came back that, because Dr. C had to work so long to remove the tooth, she was not willing to make any adjustments.

T's mother contacted the insurance carrier to explain the situation. The carrier requested a pre-treatment radiograph from Dr. C, based upon which the in-house reviewers concluded that the tooth was not appropriately coded as 7240, but rather should have been 7210 (surgical extraction of erupted tooth). Under the plan provisions, Dr. C was therefore not permitted to charge any co-pay but instead accept the plan payment in full. When the insurer notified Dr. C of that, with a copy sent to T's mother (whose employer provided the coverage), Dr. C was steadfast that she was entitled to the amount billed and would send T to collection if she was not paid. T's mother did pay the claimed balance, but the carrier dropped Dr. C from the panel due to what it referenced as "upcoding resulting in excessive billing.”

Legal action

T had slowly been adapting to the lip, chin and tongue numbness, but his mother remained upset about the principle of billing her son and threatening a collection action, so she contacted an attorney. The attorney was not very familiar with oral surgery in any legal regard, so he reached out to his own dentist, with a copy of Dr. C's records that he had been provided, to help him interpret what was going on. This state did not require specialty-specific experts. The dentist agreed with the insurance company's position that the extraction had been inappropriately upcoded, but perhaps more importantly that it was clear from the records that, while T had been warned of the possibility of an inferior alveolar nerve injury and its effects, he had not been told anything about tongue numbness, which came from an injury to an entirely different nerve branch and which should have been avoided if proper technique had been employed. (As a side note, the general phrase in the consent form, "loss of sensation,” did not provide any expert reviewer with the specificity that is helpful in a defense.)

The attorney initiated a lawsuit against Dr. C, asserting lack of informed consent relating to the lingual nerve injury, dental malpractice regarding the causing of the lingual nerve injury, and breach of contract leading to the improperly billed (and collected) co-pay amount. The defense attorneys assigned to Dr. C by her malpractice carrier reviewed the case with their client and advised her that they would seek expert opinion as to the substance of the informed consent and malpractice claims, but that she would not be covered for the breach of contract claim, per a clearly stated policy exclusion.

The expert retained by Dr. C's counsel was provisionally willing to present a defense as to the malpractice claim regarding her having negligently caused the tongue numbness — but that position would need to be re-evaluated following her deposition testimony. However, there was no evidence in the record to demonstrate that she had provided any warning of a potential lingual nerve injury and its impacts. The defense expert did not see a pathway to successfully defend the claim of lack of informed consent. A second expert reviewer reached the same conclusion.

Dr. C's attorneys had a candid discussion with her. Even if the malpractice claim could likely be effectively defended, the lack of informed consent claim could not. So, T would be entitled to a monetary award regardless of which, or both, of the claims went T's way in the eyes of a jury. Dr. C agreed to have her attorneys seek to settle the claim, to be paid by the malpractice carrier, which they did. As part of the settlement agreement, Dr. C would personally return to T the amount his mother paid her for the co-pay.

Takeaways

While it is impossible to know whether T would have sought an attorney at some point to file an action on his behalf based upon the substantive oral surgery issues, it is quite clear that the issue which drove the initial attorney involvement was the billed, and eventually paid, co-pay amount. There is then perhaps a bit of irony that the money that Dr. C was unwilling to waive directly led to a settled malpractice claim, but that insisted-upon co-pay not only started the legal action steps but was also ultimately paid by Dr. C out-of-pocket. Dr. C made the decision to demand a disputed amount of money, and that decision likely cost her far more — particularly with her being dropped from a panel - than had she acquiesced in the first place. It is not our role here to advise oral surgeons as to whether they should fervently go after unpaid, disputed fees. Instead, we demonstrate a situation where doing so ended up causing more harm than benefit. Food for thought.

Experience teaches that lay jurors might not always understand scientific, dental/surgical facts, sometimes making their determinations counter to what experts and attorneys anticipate. On the other hand, issues relating to overbilling or upcoding are relatively straightforward for plaintiffs' attorneys to explain to jurors, and simple for them to understand. At times, jurors might put all else aside and render a verdict for a plaintiff if they do not see the defendant-dentist as having been honest. Such is a version of jury nullification, with the jury members substituting what they deem critical, in place of what the law says is critical. Taking subjectivity of that type out of the hands of juries increases a defendant's chances for success.

This case study exemplifies how the trigger for a patient seeking legal counsel might have nothing at all to do with the quality of surgery performed. Yes, oral surgery is complex, and there is an ever-present unpredictability factor, so ideal results do not happen with every procedure, with every patient. What need not be complex are matters over which surgeons and their staff members have full control; such matters can virtually always be taken out of the equation as to what starts the legal ball rolling.

Finally, we briefly address the coding of procedures for billing purposes. The ADA and perhaps other associations provide numerical codes for dental procedures, which state the procedure performed and which often serve as the basis for which payment is sought and made. With few exceptions — such as 7241 for full impactions with unusual surgical complications, or time under sedation/general anesthesia, as examples — procedure codes do not take into account the length of time required to complete or the difficulty in doing so. To upcode to a procedure not actually performed, for a higher fee, is to invite a host of problems, including the initiation of a malpractice lawsuit or Dental Board complaint.

Summary of takeaways

A billing dispute can quickly escalate into legal action, even when the original concern is not directly related to clinical care.
Accurate coding matters because upcoding or disputed fees can damage patient trust and increase liability risk.
Clear, specific informed consent documentation helps support a stronger defense if complications occur.

Background facts

Dr. G was an oral and maxillofacial surgery resident, in the third of six years of training. She spent most of her current time on off-service rotations, so she was able to moonlight outside of the hospital, which was a practice permissible in her program. To properly protect herself, Dr. G obtained malpractice insurance, which allowed for part-time non-resident work; inasmuch as she was not yet an oral surgeon, her premium was set as would be done for a general dentist performing oral surgery.

On a typical day in the busy, urban dental office, Dr. G generally treated between 10 and 15 patients, performing the extraction of impacted and non-impacted teeth, with an occasional root resection, apicoectomy, or biopsy. R, a 22-year-old man, presented with an episodically symptomatic, deeply impacted lower left third molar; he was directed to see Dr. G for evaluation and potential treatment. On the panoramic film that Dr. G reviewed, tooth #17 was fully imbedded in bone, with a mesioangular inclination so as to create a clinically-evident periodontal defect on the distal aspect of the adjacent second molar. Dr. G suggested to R that the wisdom tooth be extracted, with a bone graft placed into the socket. Because of the radiographic relationships that were visible and noted, clear warning was given about the realistic potential for left inferior alveolar nerve injury, and those effects, but little else was provided in terms of risks, even according to Dr. G's chart entry. The office had no written consent forms.

Under local anesthesia, Dr. G sectioned the tooth, taking note as she proceeded of the angulation of the crown toward the lingual. Exercising appropriate care to surgically stay away from the lingual plate and gingiva, the tooth was removed in sections, seemingly uneventfully; but as the crown portion was elevated out, what appeared to be an intact lingual nerve became visible immediately above the height of bone. The site was carefully debrided and irrigated, with a small amount of bone graft material placed just behind tooth #18. Because of Dr. G's hospital schedule, she knew that she would not be able to return to the office for 2 weeks, so she placed a chromic gut suture and advised R to return if he had any problems. Dr. G wrote a detailed chart entry, chronicling every surgical step and including her findings regarding the lingual nerve.

R never returned, and nobody from the office, including Dr. G, attempted to contact him: because of the large patient volume, post-treatment calls were not very feasible, given the few administrative staff members.

Legal action

No word was heard from or about R until the office received a letter, some 10 months after treatment, from an attorney representing R. The letter requested complete copies of R's records; the office complied but did not inform Dr. G of the request or compliance. Approximately 3 months later, a process server appeared at the hospital's oral surgery clinic and handed Dr. G a copy of the papers initiating a lawsuit against her. The Complaint alleged professional negligence — dental malpractice — for improper surgery that resulted in left-sided tongue numbness and taste loss, as well as lack of informed consent. After gathering her thoughts, she contacted her malpractice insurance carrier, forwarded what she was given, asked the office to forward to her carrier a copy of R's office records, and was ultimately contacted by the attorneys hired to represent her.

In the first lawyer-client meeting, the litigation process was discussed with Dr. G. In turn, Dr. G described her surgical technique, as had been documented, which sounded "textbook" to her attorney, who was well-experienced in defending dental malpractice cases. The attorney expressed concern about there being no written consent form, compounded by the limited statement of risks in the chart entry, which ignored injury to the lingual nerve and, by extension, the chorda tympani. At the conclusion of the meeting, the attorney discussed his next immediate steps, which included obtaining a very preliminary expert review from a general dentist who performed many extractions. (The State in which the lawsuit was filed required that all experts be of the same area of practice as the defendant; because Dr. G was still in training, she was a general dentist.)

Pending depositions and other discovery, the potential expert supporting Dr. G was of the opinion that her description of the surgery lacked any defects, with the resulting injury being a function of the anatomic relationships at play, namely the tilt toward and proximity of the crown to the lingual nerve complex. As to the issue of lack of informed consent, the expert's opinion was that, in the world of general dentists, although not oral surgeons, written consent forms for surgical procedures were the exception rather than the rule, and risk discussions by general dentists, although not by oral surgeons, were usually quite limited, with Dr. G's documented risk statement falling well within that general-dentist-based parameter.

Discovery proceeded with no surprises and no changes in defense expert opinion. All involved prepared for trial, with disclosures of anticipated expert testimony shared. On the first day of trial, but before seating the jury, R's (plaintiff's) counsel made a motion in limine — a pretrial request to exclude certain testimony or other evidence — to bar Dr. G's expert from setting forth standards of care, regarding surgical technique, informed consent, or otherwise, that were different as between general dentists and oral surgeons. If successful, Dr. G's expert would not be able to argue that Dr. G, as a general dentist (in reality), should not be held to meet the informed consent standard of care of oral surgeons regarding written consent forms and the extent of surgical risks discussed with R.

The trial judge ruled that Dr. G's expert would not be able to draw the distinction planned between oral surgeons and other dentists. In short, the court said that it is the procedure, not the practitioner, that carries the standard of care. Allowing for such differences would prejudice patients such that those having surgery performed by dentists who are not oral surgeons would essentially be signing on to a lesser level of care, which would not be proper. Dr. G remained confident that she had performed the surgery appropriately in all respects, but she understood the implications of the court's decision as it related to her obtaining of informed consent from R, namely that her process did not meet the standard for the procedure. She agreed to try to reach a settlement, and that was accomplished before the first words were spoken at trial.

Takeaways

The ruling by the judge in this isolated case is one that is quite commonly, although not necessarily universally, adopted by courts. As stated here, the basis for that is the protection of patient safety, a frequent theme of many court decisions on any number of issues. The lesson, though, is clear: any practitioner who undertakes any procedure should understand that their actions in doing so will be held to the standards of experienced practitioners with focused training. Oral surgeons might well read this concept and reason that it does not affect them, given their superior training; but the application to oral surgeons is most relevant to newer practitioners who, despite their strong academic backgrounds, simply do not have very much in-practice experience. That comes with time and repetition, with a learning curve to get there.

As we have discussed in other case studies, the impact of lack of informed consent is often underestimated, but it ought not be that way. Here, Dr. G committed no malpractice surgically, at least as the description describes, but the informed consent process fell short, with that alone leading to a result for the plaintiff. The informed consent process is far more than just a throwaway to check off a box, but rather an integral part of surgery, with ramifications of deficiencies having the same ultimate litigation effect as negligently carried out surgery.

While this case study does not directly address the propriety of a panoramic radiograph as compared with a 3-D imaging study such as a CBCT, it is the proverbial elephant in the room. It would be hard to disagree with the concept that 3-D imaging is preferred so as to help in identifying anatomic relationships and potential hazards. But whether use of a CBCT constitutes standard of care will ultimately boil down to dueling opinions of experts for the plaintiff and the defendant, both subject to cross-examination. Standards of care are not published, but if they were, it would be unlikely to see such a publication make its way into trial evidence, for the reason based upon the age-old attorney mantra that a lawyer cannot cross-examine a piece of paper. As of this point in time, opposing experts strongly sit on both sides of the issue regarding the type of imaging appropriate for a given situation, and that is where the world of litigation will remain, at least for the near future. Oral surgeons would do well to determine for themselves what their judgment of choice is, and have a solid line of reasoning to support it.

Moonlighting residents and newer oral surgeons who travel between offices, often not their own, face a number of challenges to go along with the benefits. Weighing them has surgical-legal implications that might not become apparent until years after the fact.

Summary of takeaways

Practitioners are held to the standard of care for the procedure performed, regardless of their training level or practice designation.
Informed consent is a critical part of surgical care, and deficiencies in the process can carry significant malpractice risk.
Oral surgeons, residents, and traveling practitioners should carefully evaluate imaging decisions, documentation practices, and office processes before performing procedures.

Summary of takeaways

External pressures should never outweigh clinical judgment when determining the most appropriate treatment plan.
Not every treatment option is suitable for every patient — anatomy, provider experience, and overall risk must be carefully evaluated before proceeding.
When complications occur, treatment decisions that fall outside the standard of care can increase liability exposure and lead to malpractice claims.
