下颌角整形术的手术设计与临床应用

Surgical design and clinical application of the mandibular angle plastic surgery

下颌角整形术通过对咬肌切除、下颌角区的骨质截除、骨外板骨质磨除等方法以达到改善下面部轮廓的目的。下颌角整形术主要包括咬肌肥大矫治与下颌角肥大骨质矫治2个方面,经历下颌角截骨术式改良到数字化外科手术设计的不断进步,并逐步与颧骨颧弓整形术和颏成形术联合应用,以塑造更完美的面部轮廓比例。该文对下颌角整形术的手术设计与临床应用进行系统阐述,探讨其适应证,总结发展规律,同时对未来发展方向提出展望。

Mandibular angle plasty aims to improve the lower facial contour through procedures such as masseter muscle resection,ostectomy in the mandibular angle area,and external cortex bone grinding.This surgery primarily addresses hypertrophic masseter muscle correction and hypertrophic mandibular angle bone correction.The procedure has evolved from modifications of mandibular angle osteotomy to advancements in digital surgical design,gradually integrating with zygomatic arch plasty and genioplasty to achieve more harmonious facial proportions.This paper systematically elaborated on the surgical design and clinical application of mandibular angle plasty,discussed its indications,summarized developmental trends,and proposed prospects for future advancements.
