Patient Sentiments Influencing Management Strategy for Single-sided Deafness.

OBJECTIVE: Assess opinions that influence treatment choice for single sided deafness (SSD). STUDY DESIGN: Retrospective chart review. SETTING: Tertiary neurotology referral center. PATIENTS: Patients with SSD were recruited between December 2020 and February 2021. Included patients were self-selected by voluntary completion of the study questionnaire. MAIN OUTCOME MEASURES: Tinnitus Handicap Inventory (THI), Hearing Handicap Inventory for Adults (HHIA), and a questionnaire containing 25 areas of inquiry relevant to management strategy decision making. RESULTS: In comparison to the surgical management group, patients opting for nonsurgical amplification were significantly more concerned about device visibility (p = 0.005, 1.32 ±â€Š0.22 versus 2.67 ±â€Š0.37), undergoing surgery (p = 0.017, 1.64 ±â€Š0.23 versus 2.89 ±â€Š0.51), and the thought of harboring an implanted device (p = 0.003, 1.46 ±â€Š0.22 versus 2.82 ±â€Š0.35). Patients with a major hearing handicap (grade 2-4) placed significantly less emphasis on out-of-pocket costs (p = 0.049, 2.38 ±â€Š0.17 versus 2.94 ±â€Š0.21) and were less concerned about experiencing discomfort from the device (p = 0.033, 3.13 ±â€Š0.11 versus 3.56 ±â€Š0.16) or ease of device use (p = 0.040, 3.20 ±â€Š0.13 versus 3.63 ±â€Š0.13) when compared with the minor handicap group. CONCLUSIONS: Lingering concerns about device visibility, undergoing surgery, and harboring an implanted device underscore the need for thorough patient counseling during SSD device selection consultations. These efforts should aim to address esthetic and surgical risk concerns while emphasizing the potential for improvements in quality of life.

Frequency-specific Electrocochleography and Traveling Wave Time as a Clinical Test for Menière's Disease.

INTRODUCTION: Menière's disease is a clinical entity with no definitive objective testing. It has been hypothesized that underlying endolymphatic hydrops stiffens the basilar membrane leading to increased speed of the acoustic stimulus, therefore traveling wave velocity has been proposed as an objective test to aid in the diagnosis. The objective of this study is to compare electrocochleography frequency-specific action potential latency, basilar membrane traveling wave time, and summation to action potential (SP/AP) ratio in Menière's and non-Menière's patients. METHODS: Tympanic electrocochleography was performed with frequency-specific action potential latency time and SP/AP ratio recorded. Patient demographics, symptoms, audiogram data, AAO-HNS classification of Menière's disease, management interventions, and follow-up were recorded. Statistical analysis was performed to compare outcome measures across patient groups, demographics, and clinical data. RESULTS: Ninety-one patients (182 ears) were included. There was a significant difference between a "definite" Menière's diagnosis and an "unlikely" or "probable" diagnosis by an average of 13 dB HL for the pure-tone thresholds at 250 Hz on the affected side (p = 0.006). There was no significant difference in pure-tone thresholds at any other frequency, AP latency at any frequency, or AP/SP ratio between the different Menière's classification groups. CONCLUSIONS: Our study fails to show significance of the traveling wave velocity as an objective test for Menière's disease. A significant correlation was found with low-frequency hearing loss between AAO-HNS Menière's classification groups.
