摘　　要：目的:探索一种简单有效而且风险小的下颌角肥大矫治术。方法:对76例下颌角肥大患者随机分为两组,均采用口内入路。A组37例,全部应用传统的摆动锯进行下颌角截骨术;B组39例,全部应用直角钻打孔法截骨,即在下颌角的预设截骨线上打一排全层穿通的小孔,然后用骨凿凿下要切除的下颌骨。结果:B组患者术中及术后出血明显少于A组,B组术中未有1例损伤知名血管,而A组有3例分别损伤了面动脉和下颌后静脉,术后B组较A组患者肿胀轻,恢复快。随访6个月～1年,两组患者下颌角间距明显变小,外形满意,两组患者满意率没有明显差别。结论:直角钻打孔法截骨和摆动锯截骨矫治下颌角肥大都能达到满意效果,但前者比后者更安全、并发症更少、风险更小。Objective To study a simple and effect way of correcting prominent mandibular angle by using intraoral approach. Methods 76 patients with various degrees of prominent mandibular angle were divided into two groups randomly. 37 cases were treated with oscillating saw in A group;39 cases were treated with right angle bur in B group.All cases were performed through intraoraJ approach. Results Compared with A group, patients in B group had less bleeding and complication during operation and postoperative. The overwith of the lower face was effectively corrected in all cases. The cosmetic results determined by both patients and surgeons were followed up 6 to 12 months postoperative. Conclusion Osteotomy with right angle bur or oscillating saw by intraoral approach can achieve a satisfactory result, but the former is simpler and less complication than the latter.
