Background: The present study was conducted for evaluating efficacy of Computed Tomography in Chronic Suppurative Otitis Media. Materials & methods:The present prospective study was conducted on50 consecutive adult cases of unsafe CSOM presenting. A detailed history with regard to otorrhoea, deafness, tinnitus, otalgia and vertigo was taken and recorded. A complete general physical examination was carried out. Each of the selected cases of unsafe CSOM were subjected to CT of temporal bone. All patients were assessed and surgery was performed. The operative findings were recorded and compared to the CT scan findings. Results:While correlating the CT findings with surgical finings, it was seen that sensitivity and specificity for soft tissue masses was 92.7 percent and 100 percent respectively.Sensitivity and specificity for presence of disease was 97.2 percent and 71.8 percent respectively. Sensitivity and specificity for malleus erosion was 92.3 percent and 91.3 percent respectively. Sensitivity and specificity for incus erosion was 73.2 percent and 75.9 percent respectively. Sensitivity and specificity for stapes erosion was 49.1 percent and 35.7 percent respectively. Conclusion:Otologists should use CT findings it more often, especially in complicated cases as an adjunct to better preoperative assessment, and thus, the surgical outcome.
