Objective To assess quality-of-life (QoL) outcomes after modified subtotal petrosectomy with ear canal closure (mSTP) for chronic otitis media. Study Design Survey study. Setting Tertiary referral center. Patients Patients with chronic otitis media. Interventions mSTP. Main Outcome Measures Survey results from enrolled patients on the validated disease-specific Chronic Ear Survey (CES) and Chronic Otitis Media Outcome Test-15 (COMOT-15) regarding their current state of health and, if surgery was performed within 3 years of enrollment, their state of health before mSTP. Results A total of 23 patients were studied, including 19 who underwent surgery within 3 years of enrollment. Postoperatively, mean total CES scores were 80 and COMOT-15 scores were 41, with a higher CES and a lower COMOT-15 indicating better QoL. There were statistically significant improvements after mSTP in the CES activity restriction (25% difference; p = 0.008), symptom (17% difference; p = 0.007), and medical resource (13% difference; p = 0.03) domain and total (18% difference; p = 0.006) scores. In addition, there were statistically significant improvements in the COMOT-15 ear symptom (−22% difference; p < 0.001) domain and total (−16% difference; p = 0.01) scores; however, improvements in the hearing function and mental health domains did not achieve statistical significance. Postoperative COMOT-15 total scores were significantly better for patients who underwent aural rehabilitation compared to those who did not (−17% difference; p < 0.001). Conclusion Modified subtotal petrosectomy with ear canal closure is a useful intervention for patients with recalcitrant chronic otitis media, offering improved QoL in appropriately selected patients. Aural rehabilitation, when feasible, provides the potential for further QoL improvement.

Animal-induced trauma can lead to severe injury and death, especially in medically isolated settings. Few reports of hyena attacks on humans have been reported in the literature. The goal of this report is to describe such an attack and the heroic efforts required to preserve life and function in a resource-limited environment. We present a case of a 55-year-old female who was attacked by a hyena in a rural region of Ethiopia. Despite delays in medical care, she was able to survive this attack and was successfully discharged after prolonged treatment efforts. Animal-induced trauma is a potential source of substantial and disfiguring injury – especially in resource-limited environments. Early transfer to tertiary care centers and creative solutions are needed to optimize outcomes in such environments.

AbstractObjectiveDescribe the presentation and management strategy for patients with symptomatic foramen of Huschke (FH).PatientsAdults with persistent FH confirmed on imaging.InterventionsDiagnosis and management of symptomatic persistent FH.Main outcome measureResolution of otologic symptoms.ResultsA total of four patients with symptomatic, radiographically‐confirmed persistent FH were included. The majority of patients endorsed otalgia (n = 4) and otorrhea (n = 3), and only one patient was noted to have a conductive hearing loss. All patients were noted to have dynamic movement of an external auditory canal mass with mandible manipulation on examination, and all patients had an identifiable fistula on imaging. Patients underwent surgical intervention, including both preauricular (n = 2) and transcanal (n = 2) approaches, and all endorsed symptomatic resolution after convalescence.ConclusionsPersistent FH remains an uncommon and potentially underrecognized cause of otologic symptoms. Diagnosis requires a high index of suspicion, and one must rely on both key examination findings and imaging to confirm this diagnosis. In appropriately selected patients, surgical intervention can provide durable symptomatic resolution.Level of evidenceIV

Objectives/Hypothesis To review hearing preservation after microsurgical resection of sporadic vestibular schwannomas according to tumor size. Study Design Retrospective cohort. Methods Baseline, intraoperative, and postoperative patient and tumor characteristics were retrospectively collected for a cohort who underwent hearing preservation microsurgery. Serviceable hearing was defined by a pure tone average ≤50 dB and word recognition score ≥50%. Results A total of 243 patients had serviceable hearing preoperatively. Fifty (21%) tumors were confined to the internal auditory canal, and the median tumor size was 16.2 mm (interquartile range [IQR] 11.3–23.2) for tumors with cerebellopontine angle extension. Serviceable hearing was maintained in 64% of patients with tumors confined to the internal auditory canal, 28% with cerebellopontine angle extension <15 mm, and 9% with cerebellopontine angle extension ≥15 mm. On multivariable analysis, the odds ratios of acquiring nonserviceable hearing postoperatively for tumors extending <15 mm and ≥15 mm into the cerebellopontine angle were 5.75 (95% confidence interval [CI] 2.13–15.53; P < .001) and 22.11 (95% CI 7.04–69.42; P < .001), respectively, compared with intracanalicular tumors. Conclusions The strongest predictor of hearing preservation with microsurgery after multivariable adjustment is tumor size. Approximately 10% of patients with tumors ≥15 mm of cerebellopontine angle extension will retain serviceable hearing after microsurgery. Furthermore, hearing preservation techniques offer cochlear nerve preservation and cochlear patency allowing for possible future cochlear implantation. An attempt at hearing preservation, including avoiding surgical approaches that necessarily sacrifice hearing, is worthwhile even in larger tumors if serviceable hearing is present preoperatively.

OBJECTIVE Detection of vestibular schwannoma (VS) growth during observation leads to definitive treatment at most centers globally. Although ≥ 2 mm represents an established benchmark of tumor growth on serial MRI studies, 2 mm of linear tumor growth is unlikely to significantly alter microsurgical outcomes. The objective of the current work was to ascertain where the magnitude of change in clinical outcome is the greatest based on size. METHODS A single-institution retrospective review of a consecutive series of patients with sporadic VS who underwent microsurgical resection between January 2000 and May 2020 was performed. Preoperative tumor size cutpoints were defined in 1-mm increments and used to identify optimal size thresholds for three primary outcomes: 1) the ability to achieve gross-total resection (GTR); 2) maintenance of normal House-Brackmann (HB) grade I facial nerve function; and 3) preservation of serviceable hearing (American Academy of Otolaryngology–Head and Neck Surgery class A/B). Optimal size thresholds were obtained by maximizing c-indices from logistic regression models. RESULTS Of 603 patients meeting inclusion criteria, 502 (83%) had tumors with cerebellopontine angle (CPA) extension. CPA tumor size was significantly associated with achieving GTR, postoperative HB grade I facial nerve function, and maintenance of serviceable hearing (all p < 0.001). The optimal tumor size threshold to distinguish between GTR and less than GTR was 17 mm of CPA extension (c-index 0.73). In the immediate postoperative period, the size threshold between HB grade I and HB grade > I was 17 mm of CPA extension (c-index 0.65). At the most recent evaluation, the size threshold between HB grade I and HB grade > I was 23 mm (c-index 0.68) and between class A/B and C/D hearing was 18 mm (c-index 0.68). Tumors within 3 mm of the 17-mm CPA threshold displayed similarly strong c-indices. Among purely intracanalicular tumors, linear size was not found to portend worse outcomes for all measures. CONCLUSIONS The probability of incurring less optimal microsurgical outcomes begins to significantly increase at 14–20 mm of CPA extension. Although many factors ultimately influence decision-making, when considering timing of microsurgical resection, using a size threshold range as depicted in this study offers an evidence-based approach that moves beyond reflexively recommending treatment for all tumors after detecting ≥ 2 mm of tumor growth on serial MRI studies.

Objective: Despite the growing emphasis on healthcare costs, limited data address this aspect of care within the vestibular schwannoma (VS) literature. We sought to determine which strategy confers the lowest lifetime cost and greatest quality-adjusted life-years (QALYs) for patients with small- to medium-sized sporadic VS tumors. Study Design: A Markov model was created to determine the most cost-effective management algorithm. Tumor characteristics, magnetic resonance imaging surveillance schedule, treatment outcomes, and health-related quality of life values were derived from previously published data. Cost estimates were based on CMS Fee Schedule reimbursement rates. Setting: Economic Evaluation Service within the Kern Center for the Science of Healthcare Delivery. Patients: Patients diagnosed with small- to medium-sized sporadic VS. Interventions: Upfront microsurgery following diagnosis, upfront radiosurgery following diagnosis, observation with microsurgery reserved for observed tumor growth, and observation with radiosurgery reserved for observed tumor growth. Results: Across patient ages at time of diagnosis ranging from 18 to 70 years, observation with subsequent radiosurgery used for tumor growth was the most cost-effective management algorithm while upfront microsurgery was the least. When presented with a hypothetical 50-year-old patient, the strategy with the lowest lifetime cost and highest QALYs was observation with subsequent radiosurgery reserved for tumor growth ($32,161, 14.11 QALY), followed by observation with microsurgery reserved for tumor growth ($34,503, 13.94 QALY), upfront radiosurgery ($43,456, 14.02 QALY), and lastly, upfront microsurgery ($47,252, 13.60 QALY). Sensitivity analyses varying mortality rates, estimated costs, health-related quality of life, and progression to nonserviceable hearing demonstrated consistent ranking among treatments. Conclusions: When considering initial management of small- and medium-sized sporadic VSs, neither lifetime cost nor QALYs support upfront microsurgery or radiosurgery, even for younger patients. Initial observation with serial imaging, reserving radiosurgery or microsurgery for patients exhibiting tumor growth, confers the greatest potential for optimized lifetime healthcare cost and QALY outcomes.

Objective: The differential of an external auditory canal mass is broad. One rare potential cause is a pneumatocele of the tympanic membrane, which has only been described 1 other time in the literature. This report serves to describe the second case of this pathology, including its unique presentation, and benign clinical course. Methods: Case report. Results: A case is discussed in which a pneumatocele of the tympanic membrane was incidentally identified during evaluation of contralateral otologic pathology. The etiology was suspected to be habitual auto-insufflation. After cessation of this practice, the pneumatocele was noted to resolve without further intervention. Conclusion: A tympanic membrane pneumatocele represents a rare cause of an external auditory canal mass. The diagnosis can be made clinically via history, palpation, and otoscopy during auto-insufflation, potentially avoiding further diagnostic testing. Depending on the etiology, resolution can occur after lifestyle modification; however, further interventions may definitively treat the condition if so required.

AbstractAs use of hypoglossal nerve stimulators has become more widespread in the treatment of obstructive sleep apnea, certain scenarios have dictated alterations to the previously described surgical technique. This report describes a situation in which revision of a hypoglossal nerve stimulator implant was required given the need for breast cancer surgery. It serves as the first description of the contralateral rerouting of a stimulation lead to a left‐sided impulse generator and the first description of respiratory sensing lead placement within the left second intercostal space for such a device.

Objectives/HypothesisTo examine the hearing status and aural rehabilitative profile in a national cohort of patients with sporadic vestibular schwannoma (VS).Study DesignCross‐sectional surveyMethodsA cross‐sectional survey of Acoustic Neuroma Association members diagnosed with sporadic VS was performed from February 2017 through January 2019. Self‐reported results were used to determine the aural rehabilitative profile of respondents.ResultsAmong survey respondents, 62.2% (546/878) were not using any hearing‐assistive device at time of survey. For the 37.8% (332/878) that were utilizing hearing‐assistive devices, 32.8% (109/332) reported using a behind‐the‐ear hearing aid, 23.8% (79/332) used a contralateral routing of signal (CROS) hearing aid, and 21.7% (72/332) used a bone conduction device. Notably, 41.9% (278/663) of patients who previously underwent tumor treatment reported utilizing a hearing rehabilitation device at some point during VS management compared to 27.0% (58/215) of those undergoing observation with serial imaging (P < .001). Of 275 patients with functional hearing in the ipsilateral ear, 26.5% (73/275) reported having used at least one type of hearing device; 24.0% (66/275) reported use of a conventional hearing aid, 0.7% (2/275) a CROS aid, and 0.4% (1/275) a bone conduction device. Among respondents reporting ipsilateral nonfunctional hearing, 44.9% (258/575) reported having used at least one type of hearing device; 13.0% (75/575) a CROS aid, and 12.3% (71/575) a bone conduction device.ConclusionsEven among a cohort with presumably elevated literacy surrounding hearing rehabilitation options, few patients with a history of unilateral vestibular schwannoma ultimately use hearing assistive devices long‐term, suggesting that most patients sufficiently adjust to unilateral hearing loss or are unsatisfied with the benefits achieved with current device options.Level of Evidence4 Laryngoscope, 131:1378–1381, 2021
