摘　　要：目的 :探讨正畸、正颌联合治疗唇腭裂术后引起的上颌骨严重发育不良症的临床效果。方法 :临床选择腭裂术后患者 10例 (男 6人 ,女 4人 )。矫正开始前 ,先共同进行会诊确定手术方案和术前正畸的内容。术前正畸包括扩大上颌牙弓 ,整平咬合曲线并排齐牙齿 ,为手术做好准备。手术时依据上颌骨发育受限的程度设计单颌手术 ,双颌手术 ,或下颌拔除一个牙以便缩小下牙弓与有限前徙的上颌相匹配。手术之后再配合必要的术后正畸以调整牙齿咬合关系。结果 :经过正畸、正颌联合矫治 10例腭裂术后严重上颌骨发育不良的患者 ,均取得了十分明显的疗效。患者上下颌骨达到协调 ,侧面形态得到很大改善 ,牙弓形态理想 ,前牙覆牙合覆盖关系正常。患者对治疗结果均表示满意。结论 :正畸、正颌联合矫治腭裂术后严重上颌发育不良症是一种疗效显著。Objective: To study the treatment methodology of postoperative disostosis of maxilla in the patients with cleft palate by orthognathia. Methods: 10 cases (6 males and 4 females) of postoperative dysostois of maxilla in the patients with cleft palate were treated by orthognathia. Operation manners and orthodontic treatment were determined by orthodontists and surgeons before treatment. Orthodontic treatment included upper arch expansion, teeth alignment, leveling the Spee's curve etc. Operation on single jaw or double jaw, or extraction of one anterior tooth to decrease lower dlental arch and to coordinate with the upper jaw forward was conducted according to individual situations. Adjustment of intercuspids relation was conducted after operation. Results: In all the 10 cases discrepancy of upper and lower jaws were resolved, profiles of the faces were improved significantly, dental arch symmetry, physiological overjet and overbite were achieved. Conclusion: Orthognathia is effective in the treatment of postoperative dysostosis in the patients with cleft palate.
