Background: CT examination has helped in early diagnosis, accurate localisation and planning of treatment of temporal bone disease and abnormalities. The aim of the present study is to study the normal anatomical perspective and congenital lesions of temporal bone and to see the accuracy of CT in detecting intra-canalicular space occupying lesion. Methods: This prospective and observational study was carried out in 32 patients. Patients were scanned in the axial and coronal planes. The incidence and symptoms of disease wer studied according to age and gender. The radiological and intraoperative findings of different temporal lesions were studied and compared. Results: Common clinical features were hearing loss (56.2%), ear discharge (37.5%) and facial nerve weakness (37.5%). Commonest lesion of temporal bone was neoplasm. Female preponderance was noted. In our study the commonest tumor was acoustic neuroma. There was excellent correlation between CT and operative findings in case of infections and tumors. Conclusion: CT is the best method of choice in detection of temporal bone lesion.
