Key points
- Several studies have reported on the clinical application of
electrophysiologic hearing tests to predict the hearing outcome in
SSNHL, but no study has been reported on the predictive value of ASSR
in SSNHL.
- Among patients with SSNHL of ≤ 90 dB HL, 40% of patients had a worse
ASSR threshold of ≥ 15 dB HL compared to pure-tone threshold at least
one of the 0.5, 1, 2, and 4 kHz frequencies.
- Although WASSR and SBASSR groups had similar initial pure-tone
thresholds, WASSR group had significantly worse last pure-tone
thresholds compared to SBASSR group.
- The ASSR grouping was significantly associated with the hearing
recovery in univariate and multivariate logistic regression model.
- Our finding suggested that having a worse ASSR can be considered as a
one of the poor prognostic factors in SSNHL and ASSR measurements can
be used to predict the hearing prognosis of SSNHL.
