  • Abstract
  • Look Inside

 Polytomography and CT-scanning of the temporal bone and neuro-otological findings in a 11-year-old girl with left hearing impairment and facial paralysis showed the characteristic features of an unilateral inner ear anomaly. In the affected side the cochlea, vestibule and semicircular canal were intact, but the internal acoustic meatus was narrow because of abnormal bony proliferation. It was suspected that this narrowing of the canal resulted in severe hearing impairment and incomplete facial paralysis. CT-scanning is an important technique because it reveals a fine contour of the inner ear anomaly.
