This study reports on the clinical analysis of temporal bone fracture after head trauma treated over a five-year period from 1985 through 1989. Most common cause of a temporal bone fracture was a motor vehicle accidents occurring in 28/55(50.9%) patients, followed by falls in 21/55(38.2%) and head blows in 6/55(10.9%). Fractures are divided into three groups;longitudinal fracture in 39 cases(70.9%), transverse fracture in 9 cases(21%) and mixed fracture in 4 cases(7.3%). The most common physical finding on clinical examination was a bleeding from the ear canal(67.3%), followed by hemotympanum(65.3%) and facial palsy(29.1%). And the common symptoms were hearing impairment(56.4%), loss of consciousness(36.4%), dizziness(16.4%) and tinnitus(10.9%). Audiologic study was performed for 34 patients of them, 4 cases were bilateral involvement. Of impaired ears, conductive hearing loss was 13 ears(34.7%), sensorineural hearing loss was 12 ears(31.6%), and mixed hearing loss was 9 ears(36.8%). Most common concomitant disease was basilar skull fracture(69.1%). The diagnosis of temporal bone fracture is best made clinically and radiographically. The early care of temporal bone fracture is directed toward the treatment of CSF otorrhea and immediate onset facial paralysis. The delayed care is primarily concerned with hearing rehabilitation.
