采用连续动态观察狗头颅侧位和上下位定位Ｘ线片的方法，观察比较了正常对照组、腭裂组、腭裂两瓣法修复组和全裂隙植骨修复组的上颌骨长、宽、高三维方向上的变化过程。结果显示：腭裂和腭裂修复术后的上颌骨自身增长率的显著性改变始于术后２～４周，在术后１８周结束。与正常对照组相比，前颌骨的运动轨迹亦不同，揭示鼻中隔软骨的生长方向和前颌骨对上颌骨生长力传导的异常改变可能是腭裂和腭裂修复术后上颌骨生长畸形的主要原因。
Continuous dynamic observation of the skull lateral and upper and lower position positioning X-ray method to observe the normal control group, cleft palate cleft palate cleft palate repair group and the whole fracture repair group of maxillary bone length, width and height of three-dimensional The direction of the process of change. The results showed that significant changes in maxillary self-growth after cleft palate and cleft palate repair began 2 to 4 weeks after surgery and ended 18 weeks after surgery. Compared with the normal control group, the movement trajectory of the premaxilla was also different. It was revealed that the growth of nasal septal cartilage and the abnormal changes of maxillary growth force in the maxilla may be the main causes of maxillary growth deformity after cleft palate and cleft palate repair .
