Introduction: HRCT temporal bone is the key to assessment of trauma of temporal bone. The main purpose of this study was to assess the injuries occurring to temporal bone in case of trauma. Material and Methods: Institutional Ethical Committee Approval was taken prior to commencement of the present study. Written and informed consent was taken from all patients for including them into this study. Patients were selected on the basis of inclusion and exclusion criteria. A case record proforma was prepared for each patient. A total of 50 patients referred to Radio diagnosis department between February 2013 and February 2014 were selected with history of trauma and ear bleed or swelling or hearing loss following trauma. All patients were scanned on Siemens 64 slice CT scanner. Results: Ossicular injuries are not so common in cases of trauma. Fractures and hemorrhage in the middle ear was more common. We got 5 cases of ossicular injury after assessing 50 cases of trauma to ear. The incus was more commonly involved in trauma than the malleus and stapes. Conclusion: Out of the 3 ossicles in the middle ear, the incus in the most commonly involved ossicle. This is thought to be due to firm attachment of the malleus to the tympanic membrane and stapes to the oval window.
