하악 골절의 구강내 관혈적 정복술

Many treatment methods for mandibular fractures have already been used. Among them, open reduction and internal fixation is widely utilized to provide more accurate reduction and secure fixation for selected cases. The traditional approach to this procedure has been through a skin incision concealed in the submandibular or submental shadow. This extraoral approach allows the clean dissection and interosseous wiring or plating to be separated from the orally contaminated dental wiring and extraction. However, some problems such as external scar, the possibility of facial nerve injury and the failure or incomplete result of immobilization have been indicated. Open reduction performed through an oral mucosal incision was first described by Kazanjian in 1933. This technique provided adequate fixation without external scar and facial nerve injury. The purpose of this report is to present our cases and to provide a review of the technique that will be useful to surgeon.
