唇腭裂手术对上颌骨矢状向生长发育影响的研究

目的：研究唇腭裂手术对单侧完全性唇腭裂患者上颌骨矢状向生长发育的影响。方法：混合牙列期单侧完全性唇腭裂仅修复唇裂患者15例,唇腭裂术后患者18例;16岁以上恒牙列期单侧完全性唇腭裂仅修复唇裂患者15例,唇腭裂术后患者15例。所有患者均拍摄头颅定位侧位片,测量分析矢状方向的线距和角度;分别以相应年龄段的非唇腭裂正常者作为对照,采用SPSS11.0软件包对数据进行单因素方差分析（ANOVA）。结果：混合牙列期单侧完全性唇腭裂仅修复唇裂患者表现为上颌长度缩短,而唇腭裂术后患者除上颌长度的缩短外,还存在上颌位置后缩;16岁以上恒牙列单侧完全性唇腭裂仅修复唇裂患者主要表现为上颌位置后缩,存在明显Ⅲ类倾向,术后患者上颌位置后缩外,上颌长度也缩短。结论：唇裂手术及早期腭裂手术对上颌骨矢状向生长可能有干扰作用。

Surgical effects on sagittal maxillary growth in patients with unilateral cleft lip and palate

PURPOSE：To evaluate the surgical effects on sagittal maxillary growth in patients with unilateral cleft lip and palate（UCLP）. METHODS： A total of 30 nonsyndromic UCLP patients with cleft lip repair were included in this study. 15 of them were with mixed dentition and 15 with permanent dentition. Cephalograms were traced and compared with those UCLP patients who underwent repair of cleft lip and palate （15 cases and 18 cases） as well as normal individuals. The data were statistically analyzed with SPSS11.0 software package for ANOVA. RESULTS： The UCLP patients with cleft lip repair in mixed dentition showed reduce anterior-posterior length of the maxilla, while those with repaired cleft lip and palate showed both short and retruded maxilla. In adult UCLP patients with cleft lip repair in permanent dentition, a retruded maxilla was noted, while those with repaired cleft lip and palate showed both short and retruded maxilla. CONCLUSION： Early surgical repair of the cleft lip and/or palate may have negative effects on maxillary growth.
