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