Abstract

To compare the audiometric and cervical vestibular evoked muscle potential (cVEMP) outcomes of ears with superior canal dehiscence (SSCD) to outcomes from normal ears and the unaffected ears of unilateral SSCD patients. Retrospective review of clinical testing outcomes. Tertiary care specialty teaching hospital. Three subject groups were used: 21 ears of healthy subjects, ages 21 to 52 years; 58 affected SSCD ears in patients, ages 15 to 65 years; and 26 unaffected ears of unilateral SSCD patients, ages 15 to 65 years. Results of pure-tone audiometry and cervical vestibular evoked muscle potential (cVEMP) testing. SSCD ears differed from normal ears or unaffected ears of unilateral SSCD patients in 2 ways: 1) they had significantly larger air-bone gaps at 250 and 500 Hz, resulting in poorer air-conduction thresholds at those frequencies, and 2) their cVEMP thresholds at 500 Hz were significantly lower. When the cVEMP threshold was adjusted for the size of the air-bone gap on the aud...
