An Uncommon Case of Bilateral Posterior and Superior Semicircular Canal Dehiscence Syndrome

An Uncommon Case of Bilateral Posterior and Superior Semicircular Canal Dehiscence Syndrome

Semicircular Canal Dehiscences (SCD) are rare and involvement of Posterior Semicircular Canal (PSCC) and/or multiple dehiscences are even rarer. A dehiscence of any of the semicircular canals may produce various auditory or vestibular symptoms by creating an abnormal communication between the inne...
