Dr. Laxman Bhattacharjee, Mr. Sandipan Paul

Abstract :

Aim: To evaluate the role of high–resolution computed tomography (HRCT) temporal bone in patients with squamosal chronic otitis media (COM). Materials and Methods: Totally, 40 patients with squamosal COM underwent preoperative HRCT temporal bone followed by surgery. Their intra–operative findings were compared and correlated with the radiological findings, to calculate the sensitivity, specificity, positive negative predictive value & P value of HRCT temporal bone. Results: According to the present study, HRCT was highly sensitive for detecting mastoid pneumatization, soft tissue extension, ossicular erosion, tegmen and sigmoid sinus erosion, and less sensitive for fallopian canal erosion and lateral sinus fistula. It was specific for all these parameters & P– value indicates that there is statistically significant association between different findings of 2 methods except stapes. Conclusion: The present study concludes that HRCT can be recommended not only in cases suspected with potential complications but also in all cases of COM to know the extent of disease, varied pneumatization, and the presence of anatomical variations, which should alert the clinician and guide in surgical approach and treatment plan.
