Semicircular Canal Dehiscence

A vestibular disorder caused by a pathologic third window into the BONY LABYRINTH (in contrast to the normal ROUND WINDOW OF EAR and the OVAL WINDOW OF EAR). It can present with autophony, sound- or pressure-induced VERTIGO, and chronic disequilibrium among other vestibulocochlear symptoms.(From: Semin Neurol. 2020 Jan 27; 48: 58-65.)
