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，改良手术方法和开展序列化治疗实属必要
Objective: To study the effect of cleft palate in different age stages on the development of maxillary bone in three dimensions after operation. Methods: 40 patients with cleft palate were divided into 3 groups according to the age at the time of operation, namely, the younger age group (2 ~ 5 years old), the middle age group (9 ~ 11 years old), the older age group (older than 15 years) The same age group of patients without surgery (a total of 30 cases) were carried out by X-ray films and dental occlusion model comparison analysis. Results: In the younger age group, maxillary length and width were limited (P <0.05). In the middle age group, the width of the maxilla was affected (P <0.05). The surgery of the large age group and the development of the maxilla were unaffected. Conclusion: Palataloplasty has a significant inhibitory effect on adolescent maxillary growth. The younger the operation, the more severe the effect. Therefore, it is necessary to improve the surgical method and serialize the treatment
