[Computed tomography of the temporal bone for the diagnosis of facial nerve neurinoma].
The present retrospective study of 6,200 subjects with temporal bone pathology allowed for the identification of a group of 12 patients aged between 12 and 59 years in whom the presence of facial nerve neurinoma diagnosed by computed tomography was confirmed during surgical intervention and by histological methods. The patients were allocated to three groups depending on the localization of neurinoma. Patients of group 1 (n=8) had neurinoma of the mastoidal segment, those of group 2 presented with neurinoma of the tympanic segment, and patients of group 3 showed combined lesions of the tympanic and labyrinthine segments. Clinical and CT characteristics of each group are presented. CT of the temporal bone is shown to provide a tool of high informative value for the diagnosis of facial nerve neurinoma. It is suggested that CT should be used to examine patients with facial nerve paresis or conductive and mixed hearing loss of unspecified etiology for the early diagnosis of facial nerve neurinoma.
