Diagnostic scannographique des surdites de perception: a propos de 42 cas

Forty two patients with perception deafness were explored in Thameur and la Rabta hospitals of Tunis between 1988 and 1991. The authors compared results of auditory functional exploration with those of CT scan. This study confirmed the auditory importance of evoked potentials which guide the indication of CT scan for retracochlear deafnesses. CT scan easily identifies nature, extension and surveillance after treatment
