2개의 Miniplates를 이용한 하악골 우각부 골절의 치료

Treatment of mandibular angle fractures using two noncompression miniplates

The purpose of this study was to evaluate treatment with two noncompression miniplates for patients with mandibular angle fractures. 21 consecutive patients with noncomminuted fractures of the mandibular angle were treated by open reduction and internal fixation using two noncompression miniplates and 2.0mm self threading screws placed through a transoral incision with transbuccal trochar instrumentation. The patients were placed into postsurgical MMF(maxillomandibular fixation) for 48 hours. All of the patients have showed good postoperative functions and have not experienced complications requiring second surgical intervention. Some of the patients experienced sensory disturbances on the lower lip and chin, but the symptoms disappeared within a year. Thus, the use of two noncompression miniplates seems to be relatively easy and effective for the teatment of fractures of the mandibular angle.
