소음성난청에서 구형낭 기능의 평가 = Assessment of Saccular Function in Patients With Noise Induced Hearing Loss

다국어 초록 (Multilingual Abstract)

Background and Objectives: Considering saccular receptors are coupled physically with the auditory receptors,
VEMP test may provide the information that in the noise induced hearing loss with or without dizziness, damage
to the vestibular system, especially saccule is a potential organ with cochlear damage.
Material and Methods: 11 patients (22 ears) with HF-SNHL greater than 55dB and 10 patients (10 ears) with
sudden hearing loss of varying degree HL as positive control but without clinical manifestations of vestibular
pathology tested for vestibular function test was enrolled. VEMP test was done. The results were compared with
those of 9-healthy referents (18 ears) examined in the same way.
Results: VEMP wave was significantly abolished as twelve of 22 (54.5%) with HF-SNHL, five of 13 (38.5%)
and Control group (100%). Though there was no statistically significant relation with P13, N23 latency delay in
each group, NIHL showed P13, N23 latency delay trend compared with controls.
Conclusions: Patients with noise induced hearing loss showed significantly more saccular deterioration, estimated
as negative VEMP responses than did the controls. This suggests subclinical disturbances of the vestibular system
especially of the saccule in noise induced hearing loss.
