How Often Do Oral Maxillofacial Surgeons Lose Malpractice Cases and Why?

PURPOSE: Although oral maxillofacial surgeons (OMSs) carry high legal risk in malpractice lawsuits, data elucidating the reason behind those claims and their outcomes are scarce. The purpose of the present study was to characterize the trends, analyze the payouts, and determine the etiology of malpractice cases against OMSs. MATERIALS AND METHODS: A retrospective case series study was performed using the Westlaw database to access medical malpractice cases filed against OMSs from 1980 to 2017. The inclusion criterion was that the defendants had included an OMS. Two of us independently collected the demographic data, verdicts, payouts, and etiology of the litigation. RESULTS: The study sample included 183 cases adjudicated from 1980 to 2017. The results highlighted the temporal and geographic trends, payout information, and etiology of the cases. The total number of malpractice cases had decreased by 60% from 2011 to 2015 compared with the previous 5 years. The greatest incidence of malpractice cases filed per 100 practicing OMSs was in New York, followed by California and Massachusetts. Ruling in favor of the defendant OMS was noted in 55% of the cases, of the plaintiffs in 40% of the cases, and had reached a settlement before trial in 3% of the cases. In the cases in which the ruling had favored the plaintiff, the average payment was $812,449.08, with a median payment of $250,000.00 (range, $13,750.00 to $14,887,525.95). Extraction cases represented 53% of all malpractice litigations. Of these, 65% had been third molar extractions that had resulted in lingual nerve injury (26%), postoperative infection (17%), wrong site extractions (15%), and death or brain damage (10%), among other injuries. CONCLUSIONS: Approximately one half of the malpractice cases favored the defendant OMS. Most cases were third molar extractions resulting in injuries ranging from lingual nerve injury to death. Complementary data from insurance companies would be helpful to provide more specific analysis of the etiology and trends of the malpractice cases.

Patch clamp recordings in inner ear hair cells isolated from zebrafish.

Patch clamp analyses of the voltage-gated channels in sensory hair cells isolated from a variety of species have been described previously(1-4) but this video represents the first application of those techniques to hair cells from zebrafish. Here we demonstrate a method to isolate healthy, intact hair cells from all of the inner ear end-organs: saccule, lagena, utricle and semicircular canals. Further, we demonstrate the diversity in hair cell size and morphology and give an example of the kinds of patch clamp recordings that can be obtained. The advantage of the use of this zebrafish model system over others stems from the availability of zebrafish mutants that affect both hearing and balance. In combination with the use of transgenic lines and other techniques that utilize genetic analysis and manipulation, the cell isolation and electrophysiological methods introduced here should facilitate greater insight into the roles hair cells play in mediating these sensory modalities.
