RESUMO
OBJECTIVE: To describe outcomes with obliteration of the mastoid and medial attic following canal wall down mastoidectomy for cholesteatoma. Our technique uses bone pate in the mastoid and cartilage in the epitympanum and supratubal recess. STUDY DESIGN: Retrospective observational study. SETTING: Tertiary medical center. PATIENTS: Ten years of sequential canal wall down mastoidectomies with obliteration from one neurotologist were reviewed. This included primary and revision cases in adults and children. MAIN OUTCOME MEASURES: Complications, location and extent of cholesteatoma, the presence of a dry ear after surgery, cholesteatoma recidivism, revision procedures, and postoperative hearing. RESULTS: Seventy-eight patients (79 ears) met inclusion criteria. There were few major complications. There was active follow-up of a year or more in 61. For these, the mean follow-up was 3.1 years, and approximately 90% had a dry cavity for the remainder of their follow-up. About half required minimal (if any) maintenance. There were five cases with residual disease, and no cases with recurrent disease. There were five cases that were considered failures, with three taking several years to manifest. There were no cases where cholesteatoma was buried in bone pate. A sizeable minority continued to have active tubotympanic disease despite successful treatment of the attic and mastoid. CONCLUSIONS: This seems to be a safe and reliable means to eradicate cholesteatoma and create a dry, low-maintenance cavity. It is not a cure for tubotympanic disease, and a small minority of initially stable cavities may fail several years following surgery. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To describe characteristics of sensorineural hearing loss (SNHL) in patients with blast-induced tympanic membrane (TM) perforations that required surgery. DESIGN: A retrospective review of hearing outcomes in those who had tympanoplasty for combat blast-induced TM perforations. These were sequential cases from one military otolaryngologist from 2007 to 2012. A total of 87 patients were reviewed, and of those, 49 who had appropriate preinjury, preoperative, and long-term audiograms were included. Those with pre-existing hearing loss were excluded. Preinjury audiograms were used to assess how sensorineural thresholds changed in the ruptured ears, and in the contralateral ear in those with unilateral perforations. RESULTS: The mean time from injury to the final postoperative audiogram was 522 days. In the ears with TM perforations, 70% had SNHLs of 10 dB or less (by bone conduction pure tone averages). Meanwhile, approximately 8% had threshold shifts >30 dB, averaging 50 dB. The strongest predictor of severe or profound hearing loss was ossicular discontinuity. Thresholds also correlated with bilateral injury and perforation size. In those with unilateral perforations, the SNHL was almost always larger on the side with the perforation. Those with SNHL often had a low-to-mid frequency threshold shift and, in general, audiograms that were flatter across frequencies than those of a typical population of military personnel with similar levels of overall hearing loss. CONCLUSIONS: There is a bimodal distribution of hearing loss in those who experience a blast exposure severe enough to perforate at least one TM. Most ears recover close to their preinjury thresholds, but a minority experience much larger sensorineural threshold shifts. Blast exposed ears also tend to have a flatter audiogram than most service members with similar levels of hearing loss.

Objective To reevaluate asymmetric sensorineural hearing loss (ASNHL) criteria used to justify magnetic resonance imaging (MRI) in the evaluation of retrocochlear tumors in a military population. Study Design Retrospective case-control study. Setting Tertiary care military medical center. Subjects and Methods Patients with military service and a history of ASNHL prompting referral for MRI, with or without retrocochlear tumors, were compared between 2005 and 2016. Predictor variables included pure tone ASNHL, speech audiometry, and a history of noise exposure. Logistic regression models for hearing asymmetries were performed, and receiver operator curves were used to calculate sensitivity and specificity. Results Thirty-eight retrocochlear tumors were identified. The MRI diagnosis rate for patients with ASHNL was 0.85%. Patients with tumors were slightly older (42 vs 37 years, P = .021) and had less noise exposure (47% vs 85%, P < .001). A sensitivity of 0.83 and a specificity of 0.58 were calculated for asymmetries ≥10 dB at 2000 Hz without adjusting for noise exposure. Instituting this imaging threshold would have reduced the number of MRI scans by half while missing 16% of tumors. Conclusion The tumor diagnosis rate among those undergoing MRI for ASNHL is low in the military population, likely because service-related noise exposure commonly causes ASNHL. Optimal MRI referral criteria should conserve resources while balancing the risks of over- and underdiagnosis. For those with a history of military service, an asymmetry ≥10 dB at 2000 Hz among patients meeting current ANSHL referral criteria is most predictive of a retrocochlear tumor.

PURPOSE: To assess malpractice claims related to the management of dizziness in otolaryngology in order to improve care and minimize the risk of litigation. MATERIALS AND METHODS: This is a retrospective review of the LexisNexis "Jury Verdicts and Settlements" database. All lawsuits and out of court adjudications related to the management of dizziness by otolaryngologists were collected. Data including patient demographics, plaintiff allegation, procedure performed, and indemnities were analyzed. RESULTS: Of 21 cases meeting inclusion criteria, 17 were decided by a trial jury and four were resolved out of court. Jury verdicts favored the plaintiff 53% of the time and a payout was made in 57% of cases overall. Average payments were higher for jury verdicts in favor of the plaintiff ($1.8 million) as compared to out of court settlements ($545,000). Two-thirds of cases involved surgery, most commonly stapes surgery. Legal allegations, including physical injury, negligence, and lack of informed consent failed to predict the legal outcome. CONCLUSIONS: Appropriate examination, testing, and referrals within a timely manner are crucial in the management of dizzy patients to avoid misdiagnoses. It is imperative that patients undergoing ear surgery are appropriately counseled that dizziness is a potential complication. The analysis of malpractice literature is complementary to clinical studies, with the potential to educate practitioners, improve patient care, and mitigate risk.

OBJECTIVE: Compare complications of vestibular schwannoma (VS) resection by surgical approach. STUDY DESIGN: Retrospective cohort. SETTING: The 2008 to 2013 American College of Surgeons-National Surgical Quality Improvement Program. PATIENTS: Adult patients with VS resection by an otolaryngologist. INTERVENTIONS: VS resection via transtemporal (TT), retrosigmoid (RS), or middle cranial fossa (MCF) approaches. MAIN OUTCOME MEASURES: Hearing preservation approaches were compared with hearing sacrificing approaches. Demographics and intraoperative factors were analyzed to identify predictors of medical and surgical complications, return to the operating room, and death. The effect of trainee presence was evaluated with respect to complications, operative length, and hospital length of stay. RESULTS: One hundred eleven VS resections were identified. Patients were predominantly women (57%) and older than 50 years (69%). The TT approach accounted for 50% of the cases, while RS (36%) and MCF (14%) were less common. The risk of any postoperative complication was 17%. There were no patient deaths. There was no difference in the overall complication rate among surgical approaches, nor in the overall, surgical, or medical complication rates between hearing preservation and hearing sacrificing approaches. Trainee presence did not change operation length, hospital length of stay, or complication rates. CONCLUSIONS: Complication rates of VS resection are no different when comparing TT, RS, or MCF approaches. Trainee involvement did not significantly affect complications. This study is limited by the inability to evaluate procedure-specific variables (e.g., facial nerve weakness and hearing preservation rates), but offers a unique survey of global 30-day complication rates reported to a large, multi-institutional, publically available database.

Objective To describe characteristics of blast-induced tympanic membrane perforations that do not spontaneously heal, evaluate the outcomes of tympanoplasty techniques, and understand the factors associated with surgical success. Setting Two tertiary military health care institutions. Study Design Case series with chart review. Subjects and Methods This study reviewed the practice of 1 military neurotologist and included all tympanoplasties for combat blast-induced perforations from 2007 to 2012, which comprised a total of 55 patients. Surgical outcomes and associated perioperative factors were examined to include size, location, bilateral involvement, timing of surgery, and surgical technique. Results Fifty-five patients (68 ears) met inclusion criteria. Thirty-six (53%) were total or near-total perforations, and 51% of patients had bilateral perforations. The overall success rate was 77%. It was 82% for lateral grafts and 70% for medial grafts, but the difference between these was not statistically significant. Age was a significant factor, with a success rate of 56% for ages 25 to 34 years, compared with 90% for 20 to 24 and >34 years. Patients who had bilateral sequential tympanoplasties also had lower success rates than those who had only unilateral surgery (62% vs 87%, P = .002). Ossicular disruptions were found in 5 ears, and cholesteatoma was discovered in 8. Surgical timing did not predict success, as the average time until repair was 153 days in successful cases and 151 days in failures. The mean conductive hearing improvement was 13.6 dB, and there were no major complications. Conclusion Tympanoplasty can be challenging in this population. Age and bilateral surgery were the only independent variables that showed significance.

OBJECTIVES: Ceruminous adenocarcinoma is a rare malignancy. However, due to the paucity of cases, this has been difficult to study. Using a population-based national database, patient demographics and survival trends were analyzed to further elucidate the management of this malignancy. METHODS: The SEER database was queried for patients diagnosed with ceruminous adenocarcinoma between 1973 and 2010. RESULTS: Twenty-two patients were identified in the database. The average age of diagnosis was between 60 and 64 years. All of the patients underwent surgical resection of the primary malignancy. Eight patients (36%) also had postoperative radiation. CONCLUSIONS: Ceruminous adenocarcinoma is uncommon but may not have as poor a prognosis as previously thought. Surgical resection alone appears to be a reasonable treatment option. Larger prospective studies are needed, but database analysis like this may provide clarity on the management of uncommon diseases.

PURPOSE OF REVIEW: Most surgeons at some point are involved in a medical malpractice case. There has been an increase in the number of manuscripts that analyse malpractice databases and insurance claims, as well as commentaries on the current medicolegal climate recently. This manuscript broadly reviews articles of interest to all providers and then focuses on malpractice in otology. RECENT FINDINGS: Medical malpractice articles (particularly topics related to otologic surgery published within the last 1-2 years) were searched. The growing body of literature can be divided into the themes of general negligence, mitigating injuries and the use of clinical practice guidelines in the courtroom as guidance for expert witnesses. SUMMARY: Recent findings suggest that the frequency of malpractice claims may be decreasing. Hearing loss and facial nerve injury are the most common injuries associated with otologic surgery. These injuries can be costly when negligence is found. Clinic practice guidelines are slowly being used as evidence in the courtroom and there are established guidelines that an expert witness must follow should a surgeon be called to give testimony.

OBJECTIVE: The aim of the study was to describe 3 cases of total auricular rehabilitation, including the novel use of iliac crest bone grafts to support bone-anchored auricular prostheses. STUDY DESIGN: This study is a retrospective case series from a single institution. RESULTS: Three cases with large lateral temporal bone and soft tissue defects were successfully treated with total auricular rehabilitation. Rehabilitation included the following: soft tissue coverage with an anterolateral thigh microvascular free flap, iliac crest-free bone graft with staged placement of a bone-anchored auricular prosthesis into the bone graft, and audiologic rehabilitation with a bone-anchored hearing aid (BAHA). All of the cases with grafts and flaps survived and were without significant donor site morbidity. Bone-anchored hearing aid abutment skin overgrowth was seen in 2 cases and was revised under local anesthesia. All of the patients had expected functional recovery on postoperative audiologic testing. Each patient continues to consistently wear his/her auricular prosthesis and BAHA during 3 years of follow-up. CONCLUSIONS: Total auricular rehabilitation is a complex task involving reconstruction of extensive soft tissue defects, bony defects, and the hearing apparatus. Acceptable cosmetic and functional outcomes and high patient satisfaction is possible in committed patients.

Subcutaneous emphysema and pneumomediastinum are rare complications following elective tonsillectomy. Although the mechanism of injury is unclear, air is thought to enter through either the buccopharyngeal mucosa during surgery or via alveolar rupture during positive pressure ventilation. Patients typically present immediately after surgery or upon anesthesia emergence. We describe a case of delayed pneumomediastinum in a 30year-old female who presented 4days after surgery. With only one other case described, we review the literature and remind the reader to be cognizant of this late complication.

OBJECTIVE: To analyze malpractice litigation trends to better understand the causes and outcomes of suits involving otologic surgeries to prevent future litigation and improve physician awareness. METHODS: Court records of legal trials from 1983 to 2012 were obtained from 2 major computerized databases-WESTLAW and LexisNexis. Data were compiled on the demographics of the defendant, plaintiff, use of otolaryngologists/otologists as expert witnesses, nature of injury, type of surgery, legal allegations, verdicts, and judgments. RESULTS: Fifty-eight unique cases met inclusion criteria and were selected for review. The most common surgeries that went to trial were mastoidectomy (48%), ossiculoplasty (21%), and tympanoplasty (16%). Eleven (19%) of the cases were resolved through a settlement before a verdict was reached. Verdicts in favor of the plaintiffs (31%) were awarded an average of $1,131,189. The most common alleged injuries were hearing loss (45%) and facial nerve injury (38%). Of the cases found in favor of the plaintiff, the most common reasons cited were improper performance of the surgery (50%), failure to properly diagnose and treat (33%), and inadequate informed consent and delay in diagnosis (22% each). Case outcomes involving pediatric patients were not significantly different than those of adults (p = 0.34); however, adults received higher financial awards on average ($1 million versus $232,000; p < 0.0003). CONCLUSION: Obtaining an appropriate diagnosis, thoroughly discussing all options and potential risks, presenting realistic expectations, and executing the surgery correctly are crucial to patient care. Understanding the reasons surgeons go to trial may assist in mitigating risk for potential lawsuits.

The authors present their experience of more than 25 years, now in excess of 1200 patients, with cerebellopontine angle tumors. This article focuses on the management of planned subtotal resection of acoustic tumors in five subjects, and unexpected "residual" discovered by MRI scanning in 10 cases, which represents, to the best of the authors' knowledge, a residual rate of 1% of operated patients. The rate of residual tumor is as high as 19% in some series and, in part, depends on the surgical approach. For the purpose of this article, the authors did not include their cases of neurofibromatosis, because these tumors behave differently than unilateral sporadic schwannomas.

The osseointegrated auditory implant (BAHA) is a system used for hearing rehabilitation through direct bone conduction. Although BAHA surgery is not difficult, the surgeon must observe meticulous technique to prevent complications. Indications for revision BAHA surgery can be divided into (1) failure of fixture osseointegration; (2) bone overgrowth; or (3) skin reaction or skin loss. This article discusses the conditions that might predispose a patient to require BAHA revision, and the steps, if any, that can be taken to prevent these complications. Specific surgical steps for revision of each of these three conditions are also addressed.

OBJECTIVE: We previously compared radiofrequency (Evac) tonsillotomy with monopolar electrosurgical (Bovie) tonsillectomy and showed significantly less pain with the Evac. Tonsillotomy leaves a cuff of tonsil behind, the significance of which is unknown. We hypothesize that Evac tonsillectomy also is less painful than Bovie tonsillectomy. STUDY DESIGN AND SETTING: We compared Evac (ENTec Evac 70; ArthroCare, Sunnyvale, CA) and Bovie tonsillectomy in a prospective, blinded fashion. Each participant had 1 tonsil removed by each device. We recorded, by side, the surgical time, blood loss, operative difficulty, pain (postoperative days 1, 3, 5, 7, 10, and 14), and the side that each patient preferred. RESULTS: Data were analyzed for 17 patients. They reported significantly less pain with the Evac (P < 0.036, F = 5.87). The Evac was preferred by 12 of 14 patients. CONCLUSION: Evac tonsillectomy is significantly less painful than Bovie tonsillectomy. Patients blinded to treatment preferred the Evac technique. SIGNIFICANCE: The Evac device decreases postoperative pain.

OBJECTIVES: The objective of this study was to compare the safety, difficulty of removal, and postoperative pain profile of radiofrequency ablation versus standard electrocautery removal of tonsils. STUDY DESIGN AND SETTING: A prospective, blinded study was designed to remove 1 tonsil with each of the 2 methods. Time of operation, estimated blood loss, difficulty of operation, postoperative pain, rate of postoperative hemorrhage, and the patient's preferred technique were evaluated. RESULTS: The operating time was significantly longer (P < 0.007) and the patients reported significantly less pain (P < 0.001) with radiofrequency ablation. There were no differences in blood loss, difficulty of operation, or postoperative hemorrhage rates. The patients preferred the radiofrequency ablation technique (P < 0.001). CONCLUSION: Radiofrequency ablation is a viable method to remove tonsillar tissue. Operating time for this procedure will likely decrease with experience. There was significantly less pain reported with radiofrequency ablation compared with standard electrocautery.
