【 摘 要 】

AIM: To identify the main tomographic findings of retrofenestral otosclerosis.METHODS: A prospective and multicentric study using computed tomography (CT) of the temporal bone in 54 patients with a clinical and surgical diagnosis of otosclerosis. A tomographic analysis has been performed to evaluate the utility of CT scans in diagnosing retrofenestral otosclerosis, verifying the sites of predilection for otosclerotic lesions. In this study, 22 patients undergone CT scans of temporal bones have been included in order to investigate other otologic diseases and have constituted the control group.RESULTS: The tomographic findings were mostly bilateral and the retrofenestral focus more prevalent was the pericochlear focus.CONCLUSIONS: The CT scan was useful in the identification of the retrofenestral focuses. The evidence of this focuses and the presence of the endosteal involvement of the cochlea can suggest a higher activity of the disease.
