Surgery-first approach (SFA) has been a paradigm shift in the field of orthognathic surgery. Majority of the published cases that have been managed by this approach are of skeletal class III. This communication describes a patient of 18-year-old male diagnosed with skeletal class II malocclusion due to mandibular retognathism. He was managed with SFA and was using skeletal anchorage system to prevent postsurgical relapse. Bilateral saggital split ramus osteotomy was carried out to achieve the mandibular advancement of 7 mm. Using this approach good esthetic result, functional occlusion was achieved. Patients were benefited with marked improvement in profile at a very early stage of treatment and shorter total treatment time of about 7 months.
手术优先方法（SFA）是正颌外科领域的一种范式转变。采用这种方法治疗的大多数已发表病例为骨性III类错牙合。本文介绍了一名18岁男性患者，因下颌后缩被诊断为骨性II类错牙合。他接受了手术优先方法治疗，并使用骨锚固系统防止术后复发。进行了双侧矢状劈开下颌升支截骨术，使下颌前徙7毫米。采用这种方法取得了良好的美学效果和功能性咬合。患者在治疗的早期阶段面部轮廓就有显著改善，总治疗时间缩短至约7个月，从中受益。
