Objective: To report the novel use of intraoperative electrically evoked stapedial reflex (eSR) for cochlear nerve monitoring during simultaneous translabyrinthine resection of vestibular schwannoma (VS) and cochlear implantation. Study Design: Clinical capsule report with video demonstration. Setting: Tertiary academic referral center. Patient: A 58-year-old female presented with a small right intracanalicular VS with associated asymmetrical right moderate to severe sensorineural hearing loss, poor word recognition, tinnitus, and disequilibrium. Based on patient symptomatology and goals, simultaneous CI with translabyrinthine resection of the VS was performed. Intervention: Cochlear implantation before the tumor was resected facilitated intraoperative eSRs by delivering repeated single-electrode stimulations through the cochlear implant (CI) electrode during tumor resection. A pulse duration of 50-us and a current amplitude of 200-CL or 648-us was used to elicit eSRs visible through the facial recess. Intraoperative eSR was monitored in conjunction with electrically evoked compound action potentials via neural response telemetry and electrical auditory brainstem response. Results: Despite the transient evoked compound action potentials amplitude and electrical auditory brainstem response latency changes, the visually observed eSR was preserved and remained robust throughout tumor dissection, indicating an intact cochlear nerve. Four weeks postoperatively, the patient exhibited open-set speech capacity (14% CNC and 36% AzBio in quiet). Conclusion: The current study demonstrates the feasibility of using intraoperative eSR via a CI electrode to monitor cochlear nerve integrity during VS resection, which may indicate successful CI outcomes. These preliminary findings require further substantiation in a larger study.

Objective: To evaluate the predictors of remnant tumor regrowth and need for salvage therapy after less than gross total resection (GTR) of vestibular schwannoma (VS). Study Design: Retrospective chart review. Setting: Tertiary neurotologic referral center. Patients: Patients who underwent VS resection between 2008 and 2019 either with GTR, near total resection (NTR), and subtotal resection (STR). Interventions: Microsurgical resection, salvage radiosurgery. Main Outcome Measures: Regrowth free interval, salvage free interval, tumor doubling rate. Results: Three hundred eighty five cases (GTR = 236, NTR = 77, and STR = 71) from 2008 to 2019 were included. STR cohort had much larger and complex tumors with significant differences in tumor volume, ventral extension and brainstem compression (p < 0.001). On single predictor analysis, tumor volume, ventral extension, brainstem compression as well as STR strategy was associated with significant increased risk of regrowth and need for salvage therapy. Multivariate analysis revealed STR strategy as significant predictor of regrowth (hazard ratio 3.79, p < 0.0005). Absolute remnant volume and extent of resection (EOR) did not predict regrowth. A small proportion of cases (NTR = 4%, STR = 15%) eventually needed salvage radiosurgery with excellent ultimate local tumor control with no known recurrence to date. Conclusions: Conservative surgical strategy employing NTR or STR can be employed safely in large and complex VS. While there is increased risk of regrowth in the STR cohort, excellent local control can be achieved with appropriate use of salvage radiosurgery. No disceret radiologic or operative predictors of regrowth were identified.

AbstractAlopecia is one of the most common reasons for a dermatology visit among Black patients. Patients with concomitant afro‐textured hair and scarring alopecias are often subjected to delays in diagnosis and treatment. Race‐discordant physicians may find the examination of scarring alopecias in ethnic hair to be daunting. Herein we present a standardized approach to evaluating the hair and scalp in afro‐textured alopecia patients in the hopes of providing a framework and guide for the proper clinical assessment of these patients. This guide focuses on common scarring alopecias specific to this ethnic population including traction alopecia, central centrifugal alopecia, frontal fibrosing alopecia and lichen planopilaris.

Abstract Background Cystic fibrosis (CF) is a multisystem disease that often requires otolaryngology care. Individuals with CF commonly have chronic rhinosinusitis but also present with hearing loss and dysphonia. Given these manifestations of CF, otolaryngologists are frequently involved in the care of patients with CF; however, there is limited consensus on optimal management of sinonasal, otologic, and laryngologic symptoms. Methods The Cystic Fibrosis Foundation convened a multidisciplinary team of otolaryngologists, pulmonologists, audiologists, pharmacists, a social worker, a nurse coordinator, a respiratory therapist, two adults with CF, and a caregiver of a child with CF to develop consensus recommendations. Workgroups developed draft recommendation statements based on a systematic literature review, and a ≥80% consensus was required for acceptance of each recommendation statement. Results The committee voted on 25 statements. Eleven statements were adopted recommending a treatment or intervention, while five statements were formulated recommending against a specific treatment or intervention. The committee recommended eight statements as an option for select patients in certain circumstances, and one statement did not reach consensus. Conclusion These multidisciplinary consensus recommendations will help providers navigate decisions related to otolaryngology consultation, medical and surgical management of CF‐CRS, hearing, and voice in individuals with CF. A collaborative and multidisciplinary approach is advocated to best care for our patients with CF. Future clinical research is needed utilizing standardized, validated outcomes with comprehensive reporting of patient outcome, effects of modulator therapies, and genetic characteristics to help continue to advance care, decrease morbidity, and improve the quality of life for individuals with CF.

Objective: The purpose of this study was to provide empirical data describing the relationship between behavioral responses to dynamic visual motion in adults with chronic dizziness symptoms with and without clinically identifiable peripheral vestibular impairment. Design: Prospective, quasi-experimental study including individuals with chronic dizziness symptoms with identified unilateral peripheral vestibular impairment (n=27), and individuals with chronic dizziness symptoms without identified vestibular impairment (n=26). We measured (a) visual perception of verticality in a dynamic background, (b) postural displacement in a dynamic background, (c) eye movement behaviors in various visual contexts, and (d) self-rating degree of anxiety. Results: Status of peripheral vestibular function was not a significant predictor of behavioral responses to visual motion. The data show that the ability to fixate on a visual target was predictive of postural control in a dynamic visual background. Trial-to-trial variability in verticality responses and degree of self-rated anxiety were also associated with postural control. Conclusions: Apart from vestibular function, oculomotor control is important for maintaining control of whole-body motor responses during exposure to a dynamic visual stimulus. Vertical perception precision—not accuracy—may be more important for understanding real-world consequences of visual motion sensitivity. Traditional diagnostic evaluations focusing exclusively on characterizing the peripheral vestibular system may not provide insight into the behaviors associated with visual motion sensitivity.

AbstractTelemedicine is a rapidly growing field of medicine due to a combination of high-speed global telecommunication systems and accessibility of small, fast mobile computing platforms with bidirectional audiovisual camera capabilities. Teleneurology is a subset of telemedicine. TeleNeuroICU, one form of teleneurology, is the practice of virtually consulting on patients in the ICU setting with neurological and neurosurgical conditions. Given the current and future shortage of neurologists and neurointensivists, there is a high demand for TeleNeuroICU services around the globe and this is expected to increase in the future. This review summarizes the state of the art around the TeleNeuroICU practice for practitioners in the field, emerging research in this area, and new technologies and integrations that enhance the value of TeleNeuroICU to health care systems.

Objective: To characterize current awareness, perceptions, and literacy surrounding hearing loss among the adult population in the United States. Study Design: National cross-sectional survey study. Setting: United States. Patients: Adults between 50 and 80 years of age in the United States. Results: Survey respondents included 1,250 adults between the ages of 50 and 80 years, including 500 who indicated at least moderate hearing loss and were using hearing aids and 750 who denied having hearing loss and were not using hearing aids. Only 9% of patients were able to correctly identify what constitutes a “normal” or “average” range for hearing. By comparison, a “normal” range of values for vision, blood pressure, and total cholesterol were identified correctly by 93%, 85%, and 52% of the 1,250 surveyed adults, respectively. When asked to rank the importance of addressing hearing loss within the context of 10 other common health conditions, hearing loss was ranked third to least important. When considering annual health maintenance, respondents indicated they were “very likely” to have an annual physical exam (72%), a cholesterol test (70%), an eye exam (66%), and bring their pet to a veterinarian (59%) over twice as frequently as having their hearing evaluated (27%). When evaluating awareness surrounding associations between hearing loss and other health and social issues, less than one-fourth indicated strong awareness about links between hearing loss and depression, employability and income, fall risk, dementia, and type 2 diabetes. While most patients acknowledge the potential impacts of hearing loss on safety, quality of life, and health, less than half believe that hearing loss is treatable and less than 20% believe that hearing loss is preventable. Conclusion: Despite widespread literacy of what constitutes normal vision, blood pressure, and total cholesterol levels, respondents exhibit substantially poorer understanding of “normal” hearing levels. Most adults believe that few treatment options exist for the management of hearing loss. Underlying the uniformly limited literacy surrounding hearing loss and its treatment options is the adult population's lack of appreciation for the long-term health sequelae of untreated hearing loss.

ObjectiveTo characterize the catchment area and patient profile of large cochlear implant (CI) centers in the United States.Study DesignMulti‐institutional retrospective case series.SettingTertiary referral CI centers.MethodsPatients who underwent CI surgery at 7 participating CI centers between 2015 and 2020 were identified. Patients’ residential zip codes were used to approximate travel distances and urban vs rural residential areas.ResultsOver the 6‐year study period (2015‐2020), 6313 unique CI surgical procedures occurred (4529 adult, 1784 pediatric). Between 2015 and 2019, CI procedures increased by 43%. Patients traveled a median 52 miles (interquartile range, 21‐110) each way; patients treated at rural CI centers traveled greater distances vs those treated at urban centers (72 vs 46 miles, P <. 001). Rural residents represented 61% of the patient population and traveled farther than urban residents (73 vs 24 miles, P <. 001). Overall, 91% of patients lived within a 200‐mile radius of the institution, while 71% lived within a 100‐mile radius. In adults, multiple regression analysis redemonstrated an association between greater travel distances and (1) older age at the time of CI and (2) residential rural setting (both P <. 001, r2 = 0.2).ConclusionsWhile large CI centers serve geographically dispersed populations, most patients reside within a 200‐mile radius. Strategies to expand CI utilization may leverage remote programming, telemedicine, and strategic placement of new centers and satellite clinics to ameliorate travel burden.

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
