Canal Dehiscence Syndrome

Superior Semi-Circular Canal Dehiscence Syndrome

SSCDS is a recently identified disorder affecting the bone of the skull base and the enclosed inner ear structures. For unknown reasons, bone of the skull base slowly dissolves exposing the superior balance canal. This allows sound to “escape” from the inner ear resulting in hearing loss. With loud noises, an extreme and sudden sensation of movement (called vertigo) may result for the patient. Active research at CEI is defining the effects and remedies available to patients with this disorder.
