Radiologic and surgical findings in chronic suppurative otitis media.
Our aim in this study was to evaluate the efficiency of preoperative temporal bone computed tomography (CT) in detecting pathologic conditions in patients with chronic suppurative otitis media (CSOM). The intraoperative findings and temporal bone CT results of 350 patients who were diagnosed with CSOM between September 1, 2010, and June 1, 2013, were compared. Comparison parameters were as follows: the presence of cholesteatoma, erosion of the outer ear bone canal, erosion of the middle ear chain, erosion of the dural plate, erosion of the lateral semicircular canal, erosion of the sigmoid sinus wall, and dehiscence of the facial canal. The contribution of CT was limited in showing the outer ear canal destruction, dural plate destruction, facial canal destruction, lateral semicircular canal destruction, and destruction of the sigmoid sinus wall. However, CT was more sensitive in detecting cholesteatoma and erosion of the ossicular chain. These results indicate that preoperative CT of patients with CSOM serves as an important guide for otolaryngologists, although there are limitations in the evaluation of the CT results.
