摘要
目的 分析双侧齿槽嵴裂二期植骨术后的植骨效果及影响植骨效果的因素。方法 对 5 1例行双侧齿槽嵴裂二期植骨的唇腭裂患者作回顾性研究。对术后随访的X线片进行植骨效果的客观评价 ,并根据手术时裂隙处尖牙的萌出情况及手术年龄 ,将患者分为A、B、C三组 ,A组为尖牙萌出前 ,B组为尖牙萌出后 ,C组年龄大于或等于 16岁 ,分析不同组别的植骨效果 ,同时分析手术类型与植骨效果的关系。结果 ①双侧齿槽嵴裂二期植骨的临床成功率为 72 .5 % ;②不同组别的植骨效果各不相同 ,三组的植骨成功率分别为 85 .7%、72 .7%和 6 5 .4% ;③除腭瘘修补术外 ,双侧齿槽嵴裂二期植骨合并其他手术的成功率与单纯齿槽嵴裂植骨的成功率相似。结论 双侧齿槽嵴裂二期植骨的最佳时机为尖牙萌出前 ,患者年龄为 8~ 14岁 ;
Objective To evaluate the treatment results after secondary bone grafting in patients with bilateral complete clefts of lip and palate.Methods A retrospective study was performed in 51 bilateral complete cleft lip and palate patients who received secondary bone grafting and with an observation period of 9 to 100 months (mean: 41.1 ).The patients were divided into three groups according to age and eruption stage of the canine at the time of surgery.The result of the bone grafting was evaluated on the radiographs.Results ①The overall success rate of bone grafting was 72.5 %;②The marginal bone level was found to be significantly higher in the youngest age group than in the other groups;③With the exception of cleft palate fistula operation,there was no difference of success rate between simple alveolar bone grafting group and other combined operation groups.Conclusion For secondary bone grafting,significantly better results can be achieved if the operation is performed before eruption of the canine.The late secondary bone grafting could face a high failure rate.
