BACKGROUND: To explore the correlation between the detection value of distortion-product otoacoustic emissions and the early prognosis of sudden sensorineural hearing loss.
METHODS: Seventy-eight patients with first-onset sudden sensorineural hearing loss (all frequencies) from April 2018 to July 2019 were included in this study. Distortion-product otoacoustic emissions and pure-tone audiometry tests were performed at days 0, 3, and 6 of admission. Repeated measures analysis of variance was performed to evaluate the changes in the signal-to-noise ratio for different distortion-product otoacoustic emissions frequencies over time and the interaction of grouping factors and time factors.
RESULTS: The distortion-product otoacoustic emissions evocation rate in the 4 groups was significantly different starting at day 3 of treatment. It was higher in the cured (35.3%) and obviously effective (20.0%) groups than in the other 2 groups (0%, 0%). At the 6 f2 frequencies of 1105 Hz, 1560 Hz, 2211 Hz, 3125 Hz, 4416 Hz, and 8837 Hz, the signal-to-noise ratio was different among the groups (P < .05) and was notably higher in the cured group. The analysis of the signal-to-noise ratio change before and after treatment at the intermediate f2 frequencies of 1105 Hz, 1560 Hz, and 2211 Hz in all patients indicated a linear correlation between the signal-to-noise ratio change and the pure-tone hearing threshold change, with a correlation coefficient of 0.481.
CONCLUSION: Distortion-product otoacoustic emissions evocation in the early stage (within 3 days of treatment) or the signal-to-noise ratio trend over time at intermediate frequencies may predict the prognosis of sudden sensorineural hearing loss.
