¸ñÀû: To analyze the characteristics of patients with noise-induced
hearing loss (NIHL) by comparing audiologic test findings between
groups with and without tinnitus. ¹æ¹ý:This study involved patients with noise-induced hearing loss (NIHL)
who presented to the otolaryngology clinic between January 2016 and
April 2019. Tests including 3 pure-tone audiometry (PTA) tests at
intervals greater than 1 week, and auditory brainstem response
(ABR) were evaluated and patients were screened for tinnitus. The
tinnitus patients had otoacoustic emission. Comparison was done
between the tinnitus group and the group without tinnitus. °á°ú:Of the 730 subjects with NIHL, 389 had tinnitus. PTA showed significantly higher thresholds at 2 kHz to 8 kHz in the tinnitus group. Although ABR tests tended to show more prolonged I, III, and V latency in the tinnitus group, the differences were not statistically significant.
Distortion product otoacoustic emissions (DPOAE) showed more abnormalities at 3 kHz, and 4 kHz than at 1 kHz and 2 kHz. Transient optoacoustic emission (TEOAE) showed abnormal findings in both ears.
°á·Ð:In NIHL, hearing loss was more severe in patients with, than
without tinnitus. DPOAE showed more abnormalities at 3 kHz, 4 kHz,
and 6 kHz than at 1 kHz and 2 kHz, and TEOAE was abnormal at all
frequencies. |
