[摘要]目的:探讨口内入路结合铣骨器械对下颌角肥大的整形效果,为下颌角肥大患者提供一种简单、有效、安全,美观的双侧对称的下颌角肥大整形方法。方法:采用口内切口,常规分离显露下颌骨,在预定的下颌骨区域使用铣骨器械、锉磨除下颌角、下颌骨缘及下颌骨外板,矫治下颌角肥大。结果:我科自2003年1月～2010年3月对46例下颌角肥大的患者施行了口内入路下颌角外板去骨术,经6～10个月的随访,双下颌角间距明显缩小,且升支及体部的角度变化不大,口外无瘢痕,满意率达95%,取得了明显的效果。结论:采用口内切口入路,使用“颌面骨电动手术器械装置”矫治下颌角肥大,是一种安全有效的好方法。

Abstract: ObjectiveTo explore the truing effect of intraoral bone milling instrument in correcting mandible angle prominence,so as to provide a simple, effective, safe, beautiful and bilateral symmetrical shaping method for patients with mandible angle prominence. MethodsAfter mandible is shown through intraoral incision and conventional separation, and then use bone milling instrument and rasp to reduce mandible angle, mandible edge and outer lamella in specified area of mandible, so as to correct the mandible angle prominence.Resultsthe Department has performed the surgery on 46 patients with mandible angle prominence since January 2003.After 6～10 months of follow-up, the distance between both mandible angles is significantly narrowed, meanwhile the ramus and body have little change in angle,there is no scar on the face,and customers' satisfaction rate is 95%,we have achieved significant results. ConclusionThe method through intraoral incisions, with "China Shengjirui maxillofacial electric surgical instruments" is a good, safe and effective way to correct the mandible angle prominence.

东方人以柔为美,下颌角肥大形成的方脸与传统观念所崇尚的瓜子脸或鹅蛋形脸为美的观念相佐。在我国人群中,下颌角肥大较为常见,其特征多以下颌角骨性增生肥大为主,且伴有不同程度的咬肌肥大,略有明显的遗传性。随着人们生活水平的提高,人们向往美、追求美、实现美成为时尚,因此要求改脸型的人也就增多。我科自2003年1月～2010年3月对46例下颌角肥大的患者施行了口内入路下颌角外板去骨术,使用“颌面骨电动手术器械装置”矫治下颌角肥大,收到了良好的效果。
1资料和方法
1.1临床资料:本组46例患者(女41例,男5例),年龄20～45岁,平均32.5岁。下颌角肥大以骨性肥大为主,表现为下颌骨外斜线部位骨质增生及侧向的向外翻转,下颌角间距超过颧骨间距,面下部过宽,呈现方型脸。10例伴有颧骨过高,2例伴有颏骨过长,34例合并咬肌肥大。求治目的均为改善面部轮廓。
1.2手术方法
1.2.1麻醉方法:全部采用局部神经阻滞麻醉+局部浸润麻醉
1.2.2手术器械:颌面骨电动手术器械”(如图1) ......
