Superior Semicircular Canal Dehiscence Syndrome
Definition of SCDS
The superior semicircular canal is one of three paired canals which in part, comprise the balance organs of the inner ear. The superior (also called the anterior), posterior, and horizontal semicircular canals sense head movements, stabilizing eye movements in response to angular acceleration.
Many patients with SCDS have often been treated for a number of otologic conditions before the correct diagnosis is made by a specialist.
