摘　　要：目的　观察腭裂修复术后腭裂隙骨性愈合状况 ,并讨论影响骨性愈合的因素。方法　对 2 0例完全性腭裂术后患者行头颅冠状CT扫描 ,观察腭裂骨性裂隙的愈合情况并测量腭裂隙内骨桥形成的位置、形态及质量。结果　 2 0例腭裂术后患者中有 13例 (6 5 % )的腭裂隙内不同程度地有骨桥形成。在形成骨桥的患者中 ,男女比例接近 ;单侧与双侧腭裂者骨桥形成情况相似 ;在不同手术年龄的患者中 ,4～ 6岁接受腭裂修复术者骨桥形成最为明显 ;所形成的腭裂隙内骨桥相对集中于双尖牙区及磨牙区前份。Objective To study the bone healing situation of the cleft palate after surgical procedure,and disccuss the factors affecting it Methods 20 patients with repaired cleft palate were examined by CT scan coronally The result of images were observed and the position, shape and quality of bone bridge were measured Results Formation of bone bridge was found in 13 cleft gaps out of 20 patients (65%),the sex ratio among patients with bone bridge was 1∶1; there was no obvious difference between unilateral and bilateral cleft palate Considering the operation age with the bone formation ,the highest percentage of bone bridge formation fell into the group of 4～6 years old, and the most occuring regions were in premolar and anterior part of molar area Conclusions There can be new bone bridge regeneration in bone gap after palate surgery,and the bone formation may have some relationship with the operation age and surgical technique
