正颌联合正畸矫治唇腭裂术后牙颌面畸形

目的以正颌外科手术联合正畸治疗的方法矫治唇腭裂术后牙颌面畸形。方法1996年以来共矫治此类畸形2l例，采用手术方法如下：Le FortⅠ型截骨术7例；多片段Le FortⅠ型截骨术5例；Le FortⅠ型截骨术加双侧下颌升支矢状劈开术（BSSRO）4例；BSSRO加颏成形术2例：Le FortⅠ型截骨术加下颌体部截骨术2例；BSSRO1例。结果2l例术后均达到模型外科设计要求，术后随访14例，平均25．6个月，九严重并发症及明显复发。12例行术前后正畸治疗者希关系及面部外形均满意，另2例个别牙齿矛台关系欠佳。结论以正颌外科手术联合正畸治疗的方法矫治成年期唇腭裂术后牙颌面畸形可取得满意结果。

Correction of dento-maxillofacial deformities following cleft lip and palate repair with orthognathic surgery and orthodontics

OBJECTIVE: To restore good occlusion and face profile, the orthognathic operation and orthodontics were used to correct the dento-maxillofacial deformities following the repair of cleft lip and palate. METHODS: 21 patients (7 males and 14 females, mean age of 20.6 years) were included in this study. Their dento-maxillofacial deformities following the repair of cleft lip and palate have been corrected in our hospital since 1996. Of them, 17 patients received pre- and postoperative orthodontic treatments. 21 cases underwent the following surgical procedures: Le Fort I osteotomy in 7 cases, multisegmental Le Fort I osteotomy in 5 cases, Le Fort I osteotomy and bilateral sagittal split ramus osteotomy (BSSRO) in 4 cases, Le Fort I osteotomy and mandibular body osteotomy in 2 cases, BSSRO and genioplasty in 2 cases, BSSRO in 1 case. Rigid internal fixation was used in all patients. After multisegmental Le Fort I osteotomy, the rigid fixed palatine splint was used for 6 approximately 8 weeks. RESULTS: Osteotomy segments healed well in all cases without severe complications. 14 patients were followed-up for an average of 25.6 months. There was no evident relapse. 12 patients who received pre- and postoperative orthodontic treatments had satisfactory occlusion and face profile. CONCLUSIONS: Orthognathic operation combined with orthodontics can be used satisfactorily to correct the dento-maxillofacial deformities following cleft lip and palate repair.
