摘　　要：正畸正颌联合治疗可用于矫治牙颌面畸形,该法有正畸优先和手术优先两种模式。手术优先的两个明显优点是缩短治疗周期和快速改善面型,但手术难度会增加。上颌缩弓较难,手术分块腭中缝可快速缩弓。本文报道1例外科缩弓的手术优先治疗的错畸形骨性Ⅲ类患者,缩弓术式11/21分块,并于7周后正畸。术后1年观察,疗效稳定。Orthodontic-orthognathic treatment can be used to treat dentofacial deformity,and it has two modes of treatment:the orthodontic-first approach and the surgery-first approach(SFA).SFA is characterized by significantly shortened duration and marked improvement in facial aesthetics,while it increases the surgical difficulty.The contraction of maxillary arch is difficult,but surgical segmentation of the palatal suture can rapidly achieve contraction.This paper reports a case of SFA treatment for a patient with skeletal classⅢmalocclusion involving 11/21 segmental maxillary osteotomy,followed by orthodontic treatment 7 weeks later,with stable outcomes observed at 1 year after orthognathic surgery.
