髂骨松质骨移植修复牙槽嵴裂21例临床分析

Clinical study of cancellous iliac bone graft in cleft alveolar repair

目的:分析影响牙槽嵴裂修复术后效果的因素。方法:对2003-2007年收治的21例牙槽嵴裂患者,采用髂骨松质骨移植修复,术后随访3～12个月,拍摄X线片,分析患者年龄、裂隙类型、手术方法以及植骨来源对手术效果的影响。结果:①手术成功率为95.24%,临床成功率为90.48%;②植骨效果与植骨年龄有关;③单侧牙槽嵴裂手术成功率优于双侧牙槽嵴裂。结论:①手术年龄以9～11岁尖牙萌出前较为合适,年龄越小,植骨成功的可能性越大;②髂骨是良好的供骨源;③良好的植骨床形成、创口的无张力严密缝合是手术成功的关键。

PURPOSE： To analyze the factors affecting the effect of cleft alveolar repair. METHODS： 21 patients with alveolar cleft who were treated in our hospital between 2003-2007 were included in this study. The factors that affected the cleft alveolar repair such as patient＇s age, cleft type, surgical method, source of bone were analyzed accordingly. RESULTS： （1） The surgical success rate was 95.24%, the clinical success rate was 90.48%; （2） The effect of bone graft correlated with the patient＇s age;（3） Surgical success rate of unilateral alveolar cleft was higher than that of bilateral alveolar cleft. CONCLUSIONS： （1） The younger patients, the greater chance of success in bone graft. Patients aged 9-11 years are appropriate candidates for the surgery , when the canine is erupting; （2） Iliac bone is a good source for bone graft; （3） Good bone bed and tight tension-free suture are the key to surgical success.
