  • Abstract
  • Look Inside

 Computed tomographic studies were carried out on patients with congenital deafness. In this series, inner ear anomalies were demonstrated in 6 ears of 4 cases, the anomalies being bilateral in 2 cases.

 In three ears from two patients, aplasia of all inner ear structures was found. On the right ear from another patient, there were anomalies of the semicircular canals associated with partial absence of the middle turns of the cochlea with presence of the basal turn. On the left ear, anomalies of the semicircular canals and vestibule were demonstrated. In the remaining patient, anomaly was only characterized by partial osseous obliteration of the basal turn of cochlea.

 CT is the examination of choice for demonstrating inner ear anomaly.
