摘要
目的：研究不同年龄阶段腭裂成形术对患者术后上颌骨三维方向上发育的影响。方法：４０例腭裂术后患者按接受手术时的年龄分成３组，即小年龄组（２～５岁）；中年龄组（９～１１岁）；大年龄组（１５岁以上），分别与同年龄组未接受手术的患者（共３０例）进行了Ｘ线头影测量片及牙牙合模型测量的对比分析。结果：小年龄组接受手术，上颌骨发育长度及宽度均受限（Ｐ＜０．０５）。中年龄组接受手术，上颌骨宽度受影响（Ｐ＜０．０５），大年龄组手术，上颌骨各方向发育不受影响。结论：腭成形术对少年期上颌骨生长有明显抑制作用，手术年龄越小，影响程度越重。因此。
Objectives: To investigate the effects of palatoplasty on the development of maxilla after operation. Methods:Computerized cephalometric analysis and dentognathic modle study were applied in 40 cases of cleft palate and 30 cases of normal control. The cases were grouped by age comparatively between those of cleft palate and control as following: ① the young- 2～5 years old; ② the middle- 9～11;③the old over 15. The data were analyzed statistically. Results:Development retard of maxilla both in length and width was observed in the young group of operated cases ( P <0.05), in width in the middle( P <0.05) and no retard in the old( P >0.05). Conclusion:Palatoplasty may retard maxilla growth in the patients younger than 11 years old. There is a great need to improve palatoplasty and to use comprehensive orthodontic treatment for the young patients with cleft palate.
