title: [Fine structure analysis of the petrous bone using high-resolution thin-layer computed tomography. 2: Place and success of CT in comparison with conventional x-ray diagnosis of petrous bone fractures].
abstract: Thirty patients with suspected petrous fractures following trauma were examined by high resolution CT and by conventional radiography. CT proved the most sensitive method for demonstrating petrous fractures and their complications. CT increased the rate of diagnosis by 17%. All fractures seen on CT could be classified, but accurate classification on the basis of conventional radiographs was only possible in 52% of cases. High resolution CT is superior in demonstrating damage to the labyrinth and the ossicles. Indications for conventional tomography are confined to atypical fractures with a course unsuitable for CT.
