Objectives/Hypothesis: To describe the pre-implant audiometric profile of adult cochlear implant (CI) recipients to investigate whether current binaural candidacy requirements prevent access to patients who could benefit from CI.Study Design: Retrospective case series. Methods: Retrospective review from 2016 to 2018 evaluating preoperative pure-tone thresholds and speech perception scores in the ipsilateral and contralateral ear.Results: A total of 252 adult CI recipients undergoing 270 implants were identified. Median age at time of implantation was 70.5 years 3) for those undergoing unilateral implantation and 59.0 (IQR 48.0-72.3) for those undergoing bilateral implantation (P < .01). For unilateral implantation, median pre-implantation speech perception performance in the ear to be implanted was 8.0% (IQR 0%-26.0%) for CNC word scores, and 9.0% (IQR 0%-34.0%) for AzBio sentence scores in quiet. Median speech perception performance in the contralateral ear was 36.0% (IQR 14.0%-60.0%) on CNC word scores, and 48.5% (IQR 17.5%-76.0%) on AzBio sentence tests. Speech perception scores were significantly different between ears for word and sentence tests (P < .01). Patients older than age 65 were significantly less likely to undergo bilateral implantation (P = .03).Conclusions: Adult CI recipients exhibit substantially poorer pre-implant speech perception scores than the commonly utilized ipsilateral qualifying threshold of 50% on sentence testing. Yet, existing insurance paradigms limit patients by excessively stringent binaural best-aided requirements. This limitation likely leads to worse device performance as patients often wait years for their binaural hearing to qualify while their ear to be implanted potentially experiences an unnecessarily extended duration of deafness. Older patients also experience a unique delay in referral for cochlear implantation.

Background: Previous cross-sectional studies analyzing quality of life (QOL) outcomes in patients with sporadic vestibular schwannoma (VS) have shown surprisingly little difference among treatment modalities. To date, there is limited prospective QOL outcome data available comparing baseline to posttreatment scores. Study Design: Prospective longitudinal study using the disease-specific Penn Acoustic Neuroma Quality of Life (PANQOL) scale. Setting: Large academic skull base center. Patients: Patients diagnosed with unilateral VS who completed a baseline survey before treatment and at least one posttreatment survey. Main Outcome Measures: Change in PANQOL scores from baseline to most recent survey. Results: A total of 244 patients were studied, including 78 (32%) who elected observation, 118 (48%) microsurgery, and 48 (20%) stereotactic radiosurgery. Patients who underwent microsurgery were younger (p < 0.001) and had larger tumors (p < 0.001) than those who underwent observation or radiosurgery; there was no significant difference in duration of follow-up among management groups (mean 2.1 yrs; p = 0.28). When comparing the total PANQOL score at baseline to the most recent survey, the net change was only –1.1, –0.1, and 0.3 points on a 100-point scale for observation, microsurgery, and radiosurgery, respectively (p = 0.89). After multivariable adjustment for baseline features, there were no statistically significant changes when comparing baseline to most recent scores within each management group for facial function, general health, balance, hearing loss, energy, and pain domains or total score. However, the microsurgical group experienced a 10.8-point improvement (p = 0.002) in anxiety following treatment, compared with 1.5 (p = 0.73) and 5.3 (p = 0.31) for observation and radiosurgery, respectively. Conclusions: In this prospective longitudinal study investigating differences in QOL outcomes among VS treatment groups using the disease-specific PANQOL instrument, treatment did not modify QOL in most domains. Microsurgery may confer an advantage with regard to patient anxiety, presumably relating to the psychological benefit of “cure” from having the tumor removed.

Objectives Urine leukotriene E4 (uLTE4) is a biomarker of leukotriene synthesis and is elevated in patients with aspirin‐exacerbated respiratory disease (AERD). It can also be useful to help delineate aspirin‐tolerant chronic rhinosinusitis with nasal polyposis (CRSwNP) patients from AERD patients. The purpose of this study is to determine if uLTE4 biomarker levels are associated with objective and subjective markers of disease severity in patients with CRSwNP. Methods A retrospective analysis of CRSwNP patients who underwent uLTE4 testing was completed to determine the association of uLTE4 levels to markers of disease severity. uLTE4 levels, as well as presenting subjective (Sinonasal Outcome Test 22 [SNOT22] scores, asthma control test [ACT] scores) and objective data (Lund‐Mackay CT score, spirometry and lab values) were collected. Results Among the 157 CRSwNP patients who met inclusion criteria, uLTE4 levels were associated with history of asthma (P < .001), aspirin sensitivity (P < .001), worse Lund‐Mackay CT scores (P = .002) and other objective markers of disease severity including serum IgE (P = .05), presenting blood eosinophil level (P < .001), and the highest recorded eosinophil level (P < .001). In subgroup analysis, associations of uLTE4 to disease markers had stronger correlations in the aspirin sensitive CRSwNP group (R range 0.31–0.52) than the aspirin tolerant CRSwNP group (R range −0.30–0.24). uLTE4 levels were not associated with subjective symptom scores (SNOT22 and ACT scores). Conclusion Elevated uLTE4 biomarker levels are associated with worsened objective markers of disease severity in CRSwNP patients but not patient‐reported symptom measures.

Podcasts are online digital audio programs that are disseminated via online subscription that are easily accessible through computers or smartphones. Increasingly, residents and medical students are prioritizing podcasts for asynchronous medical education due to ease of use, convenience (eg, use while exercising or commuting), and repeatability. Some trainees have found podcasts more useful than traditional didactic lectures. Given the increasing requirements of social distancing and the need for distance medical education platforms, podcast production can serve as a useful tool to complement resident and medical student education and is a resource that will remain accessible in perpetuity. An otolaryngology specialty podcast, “Headmirror’s ENT in a Nutshell,” was created to augment asynchronous learning and address the acute need for distance learning opportunities. Over the first 7 weeks of production, 50 episodes were created. Episodes were posted on www.headmirror.com, with subscription services available through Apple Podcast, Spotify, and other platforms.

Objective: Recurrent laryngeal nerve injury is a potential complication of cardiothoracic surgery and cause of unilateral vocal fold paralysis (UVFP). Injection laryngoplasty (IL) is an intervention offered to patients with UVFP to alleviate symptoms including dysphagia, dysphonia and weak cough. There is no definitive evidence that IL prevents pneumonia. In this study, we compare rates of pneumonia in patients with UVFP secondary to cardiothoracic surgery who did or did not undergo IL. Methods: A retrospective chart review identified patients diagnosed with UVFP by an otolaryngologist using flexible laryngoscopy following cardiothoracic surgery from January 1, 2008 to December 31, 2017. Each subject was grouped by IL status and assessed for subsequent pneumonia within 6 months of their diagnosis of UVFP. The association of IL with pneumonia was evaluated using Cox proportional hazards regression. Results: Of 92 patients who met inclusion criteria, 35 (38%) underwent IL and 57 (62%) did not. Twenty patients developed pneumonia, four who had undergone IL and 16 who had not; 12 patients developed aspiration pneumonia including two having undergone IL and 10 who had not. Those who had IL were less likely to develop total pneumonia compared to those who had not (HR = 0.33, P = .045). The protective effect of IL was not as clearly sustained when measuring for aspiration pneumonia, specifically (HR = 0.34; P = .10). Discussion: Injection laryngoplasty may reduce the risk of pneumonia in patients with UVFP secondary to cardiothoracic surgery; however, further research is needed to quantify the potential protective nature of IL in this patient population. Level of evidence: 3 (A retrospective cohort study)

Objective: To raise awareness of a unique complication associated with continuous positive airway pressure (CPAP) use after cochlear implantation to improve early detection, prevent unnecessary testing, and facilitate treatment. Study Design: Case series. Setting: Tertiary referral center. Subjects: Patients who developed subcutaneous air around the receiver-stimulator device and the associated ground electrode in the setting of CPAP usage, which resulted in open-circuit electrode failures. Main Outcome Measures: Clinical course and intervention. Results: Two patients were identified that fit this criterion. Both patients were noted to have poor implant performance secondary to high or open impedances and concomitant emphysema surrounding the cochlear implant receiver-stimulator. Manual massage offered transient improvement, but programming changes ultimately led to improved sound quality and resolution of impedance anomalies in both cases. Conclusions: Subcutaneous air collection surrounding the cochlear implant receiver-stimulator in the setting of CPAP use is an uncommon but clinically relevant complication that can be recognized by characteristic physical examination findings and impedance changes. Early and accurate recognition of this event can prevent unnecessary testing and facilitate early effective treatment.

Objective The degree to which various treatment modalities modify vestibular schwannoma (VS)–associated symptoms has received limited attention. The purpose of this study was to determine how different treatment modalities affect subjective symptoms in those presenting with VS. Study Design Prospective survey. Setting Tertiary neurotology referral center. Methods Patients with sporadic VS who received treatment at our institution were prospectively surveyed with a VS symptom questionnaire. Those who completed a baseline survey prior to treatment and at least 1 posttreatment survey were included. The prospective survey evaluated the severity of self-reported symptoms (Likert scale, 1-10), including tinnitus, dizziness or imbalance, headaches, and hearing loss. Results A total of 244 patients were included (mean age, 57 years). The mean duration of follow-up was 2.1 years, and the median number of surveys completed was 2 (interquartile range, 1-3). Seventy-eight (32%) cases were managed with observation, 118 (48%) with microsurgery, and 48 (20%) with radiosurgery. Multivariable analyses revealed no statistically significant difference in the change in tinnitus ( P = .15), dizziness or imbalance ( P = 0.66), or headaches ( P = .24) among treatment groups. Evaluation of clinically important differences demonstrated that microsurgery leads to significant bidirectional changes in headaches. Conclusions Limited prospective data exist regarding the progression or resolution of subjective symptoms in those presenting with VS. This study suggests that tinnitus, dizziness or imbalance, and headaches are unlikely to be significantly modified by treatment modality and generally should not be used to direct treatment choice.

Electrocochleography (ECochG) is an electrophysiological technique that records electrical potentials generated by different components of the inner ear and peripheral cochlear nerve in response to acoustic stimulation. ECochG responses can be analyzed into (1) cochlear microphonics (CM), (2) auditory nerve neurophonics, (3) summating potential, and (4) compound action potential. Over the past few decades, there have been ongoing refinements in technique and updates in the understanding of recorded potentials. Historically, ECochG found its main application in the diagnostic evaluation of Meniere's disease (MD). However, in the last decade, the focus has shifted towards cochlear implantation (CI). In patients with residual hearing after CI, combined electric and acoustic stimulation has resulted in improved hearing and speech outcomes. Despite efforts to mitigate trauma during electrode insertion, hearing preservation rates vary after surgery. During implantation, real‐time ECochG offers an opportunity to measure frequency specific CMs elicited from a localized region in the cochlea as the surgeon inserts the electrode array. In extracochlear ECochG recordings, the recording electrode can be placed on the promontory, the stapes, or the tympanic membrane. Intracochlear ECochG can be performed by inserting a recording electrode into the cochlea or by using one of the CI electrodes as the recording electrode. The loss of intraoperative ECochG signal may indicate cochlear trauma from electrode insertion, but the association between intraoperative ECochG changes and cochlear trauma remains controversial. The ability to monitor cochlear trauma during CI electrode placement holds promise to improve hearing preservation outcomes, modify surgical techniques, and change electrode design. The goal of this review is to provide a comprehensive overview of the electrophysiology and history of ECochG, discuss its recent applications in CI, and explore the ongoing research in this expanding field.
