Superior canal dehiscence syndrome (SCDS) is a rare medical condition of the inner ear first described in 1998 by Dr. Lloyd B. Minor of Johns Hopkins University Baltimore USA leading to hearing and balance symptoms 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. There is evidence that this rare defect or susceptibility is congenital.
