We reported on the causes of unilateral total deafness in 109 cases as well as their CT-scanning findings and their future problems during the 5 years from 1991 to 1996 at our institute.
The causes were mumps infection in 3 cases, cytomegalovirus infection in 1 case, meningitis in 1case and 102 other unknown cases.
CT-scanning was conducted on 20 of these 109 cases. Five of these 20 cases. had an abnormal view. CT scanning showed narrowness of the internal auditory meatus and hypoplasia of the cochlea and lateral semicircular ducts.
Previous reports have shown that patients have a conservative attitude and a poor understanding. The child's relatives require a careful explanation because they sometimes complain that the child was not diagnosed as unilateral total deafness at the first medical examination.
