Abstract:
To report a rare case of bilateral superior semicircular canal dehiscence (SCCD) in a child. Case report, 11-year-old female patient. Descriptive case report. Audiological findings of bilateral symmetrical low frequency sensorineural hearing loss with ascending curves and bilateral superior semicircular canal dehiscence on a high resolution computed tomography (CAT) scan. The young child presented with bilateral fluctuating hearing loss with no vestibular symptoms. She was found to have bilateral superior semicircular canal dehiscence. We hereby present a rare case of bilateral semicircular canal dehiscence found incidentally on high resolution CAT scan in a young child during work up for bilateral sensorineural hearing loss.
