Abstract
Superior semicircular canal dehiscence syndrome is a condition that mimics various otologic and vestibular problems. Diagnosis can be achieved via a combination of physical examination, audiometry, vestibular-evoked myogenic potential and high resolution computed tomography of temporal bone. We present a case of a 64-year-old lady with pulsatile tinnitus and reduced hearing in the right ear for four years. Her initial audiogram showed a right mild to moderate conductive hearing loss at low frequencies and left normal hearing at low and mid frequencies with moderate sensorineural hearing loss at high frequency, while tympanogram was type A bilaterally. A high-resolution computed tomography of temporal bone was reported as dehiscent of both superior semicircular canals. As she was able to cope with her tinnitus and her symptoms improved with time, we opted for conservative management. We highlight the importance of considering superior semicircular canal dehiscence syndrome as a differential in patients presenting with auditory and vestibular symptoms.
