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。
Objective: To study the effect of cleft lip and palate surgery on the maxillary sagittal growth in unilateral complete cleft lip and palate patients. METHODS: Fifteen patients with cleft lip were treated with unilateral complete cleft lip and palate in mixed dentition, 18 patients with cleft lip and palate after operation; 16 patients with unilateral complete cleft lip and palate in permanent dentition over the age of 16 were only repaired in 15 patients with cleft lip, After the patient in 15 cases. All patients were photographed skull positioning lateral radiographs, measurement and analysis of sagittal direction of the pitch and angle; respectively, corresponding age non-cleft lip and palate normal controls as a control, using SPSS11.0 software package for data analysis of variance (ANOVA ). Results: In patients with cleft lip and cleft lip combined with dentition alone, maxillary length was shortened in patients with mixed dentition, while maxillary length was shortened in patients with cleft lip and palate. In addition, unilateral Complete cleft lip and palate repair only cleft lip patients mainly for the position of the maxillary retraction, there is a clear tendency to type Ⅲ, postoperative patients with maxillary position after retraction, maxillary length also shortened. Conclusions: Cleft lip surgery and early cleft palate surgery may interfere with the sagittal growth of the maxilla.
