Pneumatization in Otosclerosis

Abstract

In this study, degrees of mastoid pneumatization in otosclerotic and normal patients were compared on CT scan and plain X-rays. This study was prospective, conducted on inpatients and outpatients at a large community hospital. Patients were consecutively evaluated with no sex or age predilection. Each patient had a CT scan and a Schuller graph. Temporal bone volumetric and planimetric measurements were done respectively on CT scans and Schuller graphs. Statistically no significant variations were observed between groups. No correlation could be established between the degree of pneumatization and otosclerosis. Neither imaging technique is superior to the other when they are compared.
