  • Abstract
  • Look Inside

 The authors presented two cases of unilateral congenital anomalies of the inner ear, revealed by multidirectional tomography of the temporal bones. The patientssuffered from a complete loss of hearing in one ear since early infancy, and also showed absence of vestibular function and x-ray abnormalities of the labyrinth on the deaf ear. The radiological findings were the total absence of any vestige of the inner ear structure in one case, and the presence of a rudimentary cyst-like cavity resembling no part of the normal inner ear along with narrowing of the internal auditory meatus in another case. The anomalies were classified as Michel type. Unilateral anomalies of the inner ear without associated anomalies in other part of the body are uncommon, and a survey of the literature was made.
