摘要
目的 进一步观察腭裂修复术后腭裂隙骨性愈合状况 ,统计并讨论影响骨性愈合的因素。方法 对 5 2例完全性腭裂术后患者进行头颅冠状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 ,对测量结果进行统计 ,分析其影响因素。结果 5 2例受试者中的 37例 (71% )在腭裂隙处存在有不同程度的术后腭骨板骨桥形成。经统计发现 ,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差异无显著性意义 ;在不同手术年龄的患者中 ,4～ 7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。结论 腭裂术后骨性腭裂隙内明显有新生骨桥形成 ,影响其形成的因素与手术年龄有关 ,与性别及腭裂的类型无明显关系。
Objective Attending to observe the bony healing on hard palate after palatal repair, and to discuss the factors affecting on it. Methods 52 patients with repaired cleft palate over 5 years postoperatively were examined, the CT scan of head was taken. The incidence of the bone regeneration among the patients examined was calculated, the position and quality of bone tissue were measured occording to the CT images. After all, analysis was applied to evaluate the factors affecting on the bone tissue formation. Results Formation of bone bridge was found in the 37 cleft gaps out of 52 patients (71%),the ratio of the sex among the patients who had 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 4～7 years old, and the most occurring region were in premolar and anterior part of molar area. Conclusion There could be bony healing(regeneration bone tissue RBT) after palatal repair on cleft palate patients. The operation age could be an important affecting factor to RBT, but the sex and the clinital type of cleft palate make no difference on the bone tissue formation.;
