Abstract

Objectives: This study aimed to investigate whether auditory steady-state response (ASSR) can be a prognostic indicator of hearing outcome in patients with sudden sensorineural hearing loss (SSNHL). Design: Prospective clinical study. Setting: Tertiary-care hospital center. Participants: Fifty-three patients with unilateral SSNHL of ≤ 90 dB HL were included. Patients with a worse ASSR threshold of ≥ 15 dB HL compared to pure-tone threshold were included in the worse ASSR (WASSR) group. Patients without a worse ASSR thresholds were included in the similar or better ASSR (SBASSR) group. Main outcome measures: Pure-tone audiometry (PTA) was gathered before and after steroid treatment. The hearing recovery was defined as a < 25 dB HL of final hearing level or a > 15 dB HL of hearing gain. Hearing outcome of SSNHL according to the ASSR grouping was evaluated. Results: Twenty-one patients were included in the WASSR group, whereas the remaining of 32 patients were included in the SBASSR group. Although WASSR and SBASSR groups had similar initial pure-tone thresholds, WASSR group had significantly worse last pure-tone thresholds compared to SBASSR group (p = 0.021). The ASSR grouping was significantly associated with the hearing recovery in univariate and multivariate logistic regression model (all p-values < 0.05) Conclusions: This study suggests that ASSR measurements can be used to predict the hearing prognosis of SSNHL.
