AIM To evaluate HRCT in the diagnosis of temporal bone fracture. METHODS 52 cases (56 ears) with different degrees of injuries of temporal bone were involved in the study. The chief complaints included otorrhagia, facial paralysis, hearing loss and vertigo. All patients were examined by HRCT with 1, 1.5 or 2.0 mm thick slices. Axial scans were overlapped when ossicular chain disruption was suspected. RESULTS 30 longitudinal fractures, 14 transverse fractures, 7 complex fractures, 31 facial nerve canal injury and 5 cochlear and semicircular canal injury. CONCLUSION HRCT is a reliable tool in the diagnosis of temporal bone fracture for the accuracy from the clear and detailed images.
