The present-day surgeon is blessed with an investigation and tool like HRCT which not only aids in understanding the anatomy of the vital structures but also cautions the surgeons in case of variations in its anatomy, which is critical during any surgical intervention. Objective: This study is mainly aimed at learning the minute anatomical details of the temporal bone using the HRCT, with special emphasis on its anatomical variations. Materials and methods: It is a retrospective study, all the patients who underwent HRCT in BMCRI were included in the study group.
