A bstract : Superior semicircular canal dehiscence syndrome may have a congenital basis. CT scans of 44 control and 21 dehiscent superior canals were examined to determine if dehiscent canals were more cephalically placed or vertically oriented than control canals. Results showed that neither was the case. Instead, the defect may be in the process of ossification above the superior canal.
