摘　　要：形态良好的下颌是维持面部协调的关键元素,下颌角整形也是面下部整形的重要组成部分.下颌角肥大属于下颌骨的常见畸形,主要表现为向后向下突出或外翻的下颌角所导致的下面部宽大.下颌角肥大可手术矫正,常用术式包括下颌角全层截骨术、下颌角外板矢状劈开截骨术、下颌角截骨联合下颌角外板劈开截骨术,以及下颌角截骨联合其他截骨术等,各术式有各自的适应证.近年来,数字化技术开始应用于下颌角肥大的手术治疗中,应用计算机辅助设计制造技术和3D打印技术可针对不同患者设计个性化的手术方案,还可制作用于术中截骨和定位的手术导板,以提高手术的精确性和安全性,从而获得更好的治疗效果.本文对下颌角肥大的矫正术式及常见并发症进行综述.Mandible with good shape is the essential element to maintain facial coordination. Mandibular angle plasty is an important part of lower face plasty. Mandibular angle hypertrophy belongs to the common deformity of mandible, which is mainly performed as backward and downward protrusion or eversion of mandibular angle resulting in the widening of lower face. Mandibular angle hypertrophy can be corrected by surgical methods. Common surgical methods include mandibular angle full-thickness osteotomy, mandibular angle sagittal split osteotomy, mandibular angle osteotomy combined with sagittal split osteotomy, and mandibular angle osteotomy combined with other osteotomy. Each operation has its own indications. In recent years, digital technology is applied in the surgical treatment of mandibular angle hypertrophy. Computer-aided design and manufacturing technology and 3D printing technology can design personalized surgical plans for different patients and can be used to make surgical guide plates for intraoperative osteotomy and positioning, so as to improve the accuracy and safety of surgery and obtain the best therapeutic effect. In this paper, the surgical methods of mandibular angle hypertrophy and common complications were reviewed.
