In the modern society, the development of transoprtation and industrialization brings about increasing incidence of head trauma including temporal bone fracture, which causes otologically CSF otorrhea, vertigo, facial nerve palsy and hearing loss. Conductive hearing loss is especially otologist's concern because when it continues several months after head injury, the ossicular disruption which can be corrected surgically is mostly likely. For a better understanding of pathology and treatment of traumatic ossicular disruption, we reviewed 7 cases of traumatic ossicular disruption in terms of preoperative hearing status, ossicular status, ossiculoplasty and postoperative hearing improvement. In all cases, we obtained satisfactory hearing improvement regardless of methods of ossiculoplasty ; average hearing gain is about 23 dB of air-bone gap closure.
