Abstract

Objective:To predict the prognosis of acute lowtone sensorineural hearing loss（ALHL）by using the videonystagmography(VNG) and electrocochleography(ECochG).Method:A retrospective study was done in 70 patients with ALHL after long-term follow-up. The recurrence rate and rate of progression to definite Meniere 's disease were determined according to the results of VNG and ECochG tests at the onset of the first episode of hearing loss.Result:Twentynine patients（41.4%）experienced recurrent hearing loss and 5 patients（7.1%）developed to Meniere's disease. In patients with an elevated SP/AP ratio and spontaneous nystagmus, the recurrence rate was 81.8%. However, in those with a normal SP/AP ratio and without spontaneous nystagmus, the recurrence rate was 23.3%.There was a statistically significant difference in the progression rate of Meniere's disease between the groups with(15.2%) and without spontaneous nystagmus.Conclusion:It has a certain reference value to predict prognosiswhen spontaneous nystagmus and an elevated SP/AP ratio are detected on initial examination in patients with ALHL.

Keywords: Meniere's disease; acute low-tone sensorineural hearing loss; prognosis; recurrence.
