  • Abstract
  • Look Inside

 CT findings of 5 cases of the stenotic external auditory canals were reported. Those cases included congenital atresia, carcinoma of the external and middle ear, malignant parotid tumor which invaded into external ear canal, traumatic disfigurement and protrusion of the condyle, and osteoma of the external auditory meatus. CT of the temporal bone was taken by a GE CT/T 8800 with targetimaging in 1.5mm horizontal sections. CT pictures clearly showed fine anatomical structures, extent of bone destruction and pathological disfigurement. CT was thought to give us the more valuable diagnostic informations than the conventional tomography in the cases with a narrowed external auditory canal.
