Abstract

Objectives
To analyze 125-Hz pure-tone thresholds in dizzy patients with sudden sensorineural hearing loss (SSNHL) and to investigate the relationship between 125-Hz thresholds and the prognosis of SSNHL with vertigo.
Methods
Hearing and vestibular function tests including 125-Hz pure-tone were performed in 132 patients with SSNHL and 65 subjects with normal hearing. Audiometric follow-up was performed at 6 months after initial visit. Intergroup and intragroup comparison of 125 Hz was made between SSNHL and control groups.
Results
Twenty-four patients (18.2%) had normal thresholds at 125 Hz in SSNHL group, whereas all subjects showed normal at 125 Hz in control group. None with average hearing threshold at 250 and 500 Hz≥30 dB had normal threshold at 125 Hz. There was no significant relationship between 125-Hz threshold and results of vestibular function test. There was no correlation between 125-Hz threshold and hearing recovery in SSNHL group.
Conclusions
There might be no need to assess 125-Hz pure-tone threshold in patients with SSNHL, because it is enough to evaluate thresholds of 250 and 500 Hz for low frequency.
