牙槽嵴裂植骨失败因素的探讨

Discusion of the influence factors of the failure of alveolar cleft bone graft

目的：探讨可能的导致牙槽嵴裂植骨失败的有关因素。方法：对217例病例进行临床研究，分析植骨年龄、裂隙类型以及操作方式与植骨手术成功的关系。结果：大龄患者植骨失败率显著高于9～11岁患者，双侧牙槽嵴裂失败率高于单侧，单侧完全性裂失败率高于不完全性裂和隐裂。结论：植骨年龄、裂隙类型以及操作方式是影响植骨手术成功与否的几个关键因素。双侧裂隙软组织严重缺乏者，可考虑先行一侧牙槽嵴裂骨移植术，待植入骨生长稳定后，再行另一侧植骨，手术操作动作须熟练、力度要准确，无张力严密缝合，减少手术创伤、植骨量要适度。

Objective To explore the factors whith influence the results of alveolar clefe bone graft. Methods 217 patients with alveolar cleft were discussed.we analysis the relationship between the patients＂ age,clinical classification and operation mode. Results Older patients bone graft failure rate was significantly higher than 9 to 11 patients, bilateral alveolar cleft bone grafti failure rate was higher than unilateral,unilateral complete cleft bone graft failure rate was higher than the incomplete and submucosal cleft. Conclusion The patients＇age,clinical classification and operation mode are the key factors in the alveolar cleft bone grafting.If the bilateral alveolar cleft patients＇soft tissue are lack seriously,we may be operate one side.During operation,surgical operation action must be skilled,the force should be accurate, suture should be not only no tension but also strict,surgical trauma should be reduced, the bone mass should be modest.
