Abstract
OBJECTIVE: Limited data are available on the effects of otosclerosis and otosclerosis surgery on the utricle and saccule. This study aimed to determine the effect of otosclerosis and stapedotomy on vestibular-evoked myogenic potentials.
METHODS: This retrospective study included 16 otosclerosis patients and 18 controls. Thirty-two ears of 16 patients with otosclerosis were divided into 2 groups based on whether the ear had been operated on or not. All patients and subjects underwent 500 Hz air- and bone-conducted ocular and cervical vestibular-evoked myogenic potentials testing.
RESULTS: Overall comparison of response rates showed a significant difference among the groups. Further statistical tests showed that this difference arose from differences between both operated and unoperated groups and the control group, for air-conducted cervical and ocular vestibular-evoked myogenic potentials.
CONCLUSION: Otosclerosis and stapedotomy may affect the elicitability of vestibular-evoked myogenic potentials. Otosclerosis is associated with lower response rates for air-conducted ocular and cervical vestibular-evoked myogenic potentials, regardless of whether operated on. Having been operated on does not significantly increase the response rate of air-conducted vestibular-evoked myogenic potentials.
