Superior Semicircular Canal Dehiscence (SCDS) is a medical condition of the inner ear, leading to hearing and balance symptoms to different extents in those affected. The symptoms are caused by a thinning or complete absence of the part of the temporal bone overlying the superior semicircular canal of the vestibular system. It often becomes symptomatic after physical trauma to the head or a severe pressure-altering event. The presentation can vary quite dramatically from one patient to another. The Ear and Balance Institute has one of, if not the largest, experience in the diagnosis and treatment of SSCD in the world. We have become an international referral center for SCDS. For more information about SSCD, see this book chapter authored by Dr. Gianoli.
