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 To observe the status of cleft palate fissure healing after cleft palate repair and to analyze and discuss the factors affecting the healing of bony union. Methods Fifty-two patients with complete cleft palate underwent coronal CT scan to observe the healing status of cleft palate fissure and to measure the position, shape and quality of the formation of osteopontin in cleft palate. The measurement results were analyzed and the influencing factors . Results Thirty-seven (71%) of the 52 subjects had varying degrees of postoperative palatal bone bridge formation in the cleft palate. Statistics show that in the formation of the bridge between the male and female patients in the proportion of close; unilateral and bilateral cleft palate in the formation of bone bridge was no significant difference in patients with different age, 4-7 years old patients undergoing cleft palate repair Bridge formation is most obvious; the formed bridge of cleft palate is relatively concentrated in front of the canine area and the canine area. Conclusion Cleft palate cleft osseous cleft obviously new bone formation, affecting the formation of factors related to the age of surgery, sex and cleft palate type no significant relationship.
