An evaluation of preoperative high resolution computed tomography of temporal bone in cholesteatoma

Abstract

Background: Cholesteatoma is relatively common and potentially dangerous disease of the ear. It is characterised by local destruction and osseous erosion leading to complications. High resolution computed tomography (HRCT) is the imaging modality of choice for evaluation of middle ear structures and pathology. The aim of this study is to evaluate role of preoperative HRCT in the diagnosis of the disease, its extension and complications and plan for surgery. Methods: This prospective study was conducted at a tertiary referral teaching hospital and 40 cases of cholesteatoma were selected and their pre-operative HRCT temporal bone findings and intraoperative findings were correlated. Results: This study showed good correlation between preoperative HRCT findings of cholesteatoma, and intraoperative findings. Conclusions: We conclude therefore the preoperative HRCT temporal bone is useful guide for the surgeon for the diagnosis and management of cholesteatoma.
