Superior semicircular canal dehiscence presenting as long-standing vertigo

Abstract

Superior semicircular canal dehiscence (SSCD) is a complex syndrome and the symptoms can mimic other otologic diseases. We describe a case of a female who presented with imbalance for 10 years which has been psychologically disturbing. Cervical vestibular-evoked myogenic potentials and high-resolution computed tomography scan of the temporal bone confirmed the diagnosis of SSCD. The patient's symptoms improved after the closure of the defect. SSCD should be considered as a differential diagnosis in a case of long-standing vertigo.
