Comparison of Radiological and Surgical Findings in Patients with Chronic suppurative Otitis Media

INTRODUCTION: To retrospectively evaluate the data of patients with chronic suppurative otitis media (CSOM) who were operated and who also had routine preoperative temporal bone computed tomography (CT) inorder to determine the role of preoperative CT in CSOM surgery. METHODS: Preoperative CT results and intraoperative data of 42 patients with chronic suppurative otitis media were retrospectively evaluated. RESULTS: Cholesteatoma was determined in 23 cases (54.76%) during operation and in 21 of those cases cholesteatoma presence was reported in preoperative CT evaluations. CT evaluation had a 91.30% (confidence interval (CI): 71.96%-98.93%) sensitivity and 78.95% (CI: 54.43%-93.95%) specificity regarding determination of cholesteatoma. Intraoperative ossicular chain destruction was reported in 32 (76.19%) patients and in 27 of them, CT reported ossicular chain destruction. CT evaluation had a 84.38% (CI: 67.21%-98.93%) sensitivity and 80% (CI: 44.39%-97.48%) specificity regarding determination of ossicular chain destruction. DISCUSSION AND CONCLUSION: We believe that, preoperative CT provides important data in surgical management of CSOM and for that reason all patients should be evaluated with CT in preoperative period.
