Abstract OBJECTIVES: To identify the main tomographic findings of otosclerosis and to evaluate the usefulness of high-resolution computed tomography as a diagnostic method for this osteodystrophy.STUDY DESIGN and SETTING: A prospective and multicenter Study consisting of computed tomography (CT) of the temporal bone was conducted on 54 patients with a clinical and surgical diagnosis of otosclerosis. Twenty-two patients were included in the control group.RESULTS: the CT scan was positive in 87% of the patients. the tomographic findings were mainly bilateral and fenestral foci were more prevalent.CONCLUSIONS: CT showed a high rate of positivity, mainly for fenestral lesions. Foci anterior to the oval window were the most prevalent in this population.SIGNIFICANCE: CT is useful as a diagnostic method and therapeutic indicator of otosclerosis.
