title: [Oval window canal and CT-diagnosis of peripheral pareses of the facial nerve].
abstract: Computed tomography (CT) has examined 200 patients (400 temporal bones) at the age of 0-74 with unaffected facial nerve and 28 patients with symptoms of peripheral paresis or paralysis of the facial nerve of different genesis. Polyposition CT of the temporal bone is an intravital noninvasive method of the Fallopius' canal visualization. The canal is visualized on the tomograms in 100% cases irrespective of the patients' age. The following causes of n. facialis paresis were revealed: neurinoma of the facial nerve, sarcoma of the temporal bone, destruction of the tympanic canal wall in chronic otitis media, fractures of the temporal bone, malformations of the Fallopius' canal in malformations of the temporal bone, stenosis of the canal in fibrous dysplasia. The above alterations of n. facialis canal determine further therapeutic policy.
