응급의료센터에 내원한 측두골 골절의 임상분석

Abstract

Background and Objectives: Head injuries are commonly seen in emergency medical center, but within this group only a small number of patients will have a temporal bone fracture. The aim of this study is to evaluate the clinical findings of temporal bone fractures and to compare the efficacy between traditional and petrous based fracture classification system. Materials and Methods: We reviewed charts and computed tomography scans representing 108 temporal bone fractures at regional emergency medical center. Hearing evaluation was performed in 57 cases. Results: The temporal bone fractures were predominantly occurred in 5 decades (24.8%). The most common symptom was ear bleeding which occurred 75 cases, vertigo in 20cases, TM perforation in 19 cases, tinnitus in 17 cases, facial palsy in 16 cases, and CSF leakage in 3 cases. Sensorineural hearing loss did not correlate with transverse fracture but was significantly more prevalent in petrous fractures. Also, vertigo and pneumolabyrinth were significantly occurred in petrous fracture. Conclusion: The incidence of the elderly was regional feature. Petrous based classification was significantly correlated with the occurrence of main symptoms of temporal bone fractures. (J Clinical Otolaryngol 2010;21:41–45)
