Abstract
Background : Early diagnosis and proper treatment of temporal bone fractures after an accident may be recommended.
Methods : Forty patients who were diagnosed with a temporal bone fracture among patients who visited Uijeongbu St. Mary’s Hospital Regional Emergency Center were analyzed. Age and sex, cause of the accident, time delay to otolaryngology referral, accompanying diseases, treatment in the intensive care unit, whether or not cranial injuries and cerebral decompression were performed. Radiologic evaluation for the features of temporal bone fracture line was done. Fracture lines were classified from type I to type IV according to the regional involvement. Patient symptoms, hearing and the presence or absence of facial paralysis were also analyzed.
Results : Traffic accidents and crashes were the main causes of accidents, and driver accidents and pedestrian accidents were among traffic accidents. The accompanying traumatic region was followed by the skullbase, extremities, face, chest and abdomen. In the regional evaluation of the fracture line on temporal bone, the number of cases of Type I-IV was 9, 19, 40, and 15 each. The mean air conduction of pure tone audiometry of trauma ear was 20.7 dB more decreased than healthy ear. The mean gap of air-bone conduction was 16.2 dB. The cases of facial paralysis were 5. The cases of House-Brackmann grading score (HBGS) II were 3 and HBGS III were 2.
Conclusions : It is necessary to proper inform patients of symptom and complications that may occur after a fracture of the temporal bone and prepare for proper surgical treatment and rehabilitation.
