The results of reconstruction of residual alveolo-palatal bone defects in 40 patients are evaluated clinically and radiographically in a retrospective study. Age at the time of surgery varied from 7.4 to 32.7 years. The patients were divided into two age groups: before and after 12 at the time of operation. Free autogenous anterior iliac crest bone grafts were used in 26 patients and free autogenous mandibular symphyseal bone grafts were used in 14 patients. The results show unsuccessful closure of the oronasal communication in the alveolo-palatal area of the cleft in 3 out of 31 patients. In 3 out of 40 patients, radiographic incorporation of the bone graft was unsuccessful. The radiographic success was not related to increasing experience of the surgeons. The study indicates that the best grafting results are achieved when grafting is performed before 12 years of age. The radiographic results of mandibular symphyseal bone grafts tend to be slightly better compared with results obtained with anterior iliac crest bone.
在一项回顾性研究中，对40例患者残余牙槽-腭骨缺损的重建结果进行了临床和影像学评估。手术时的年龄在7.4岁至32.7岁之间。患者被分为两个年龄组：手术时12岁之前和之后。26例患者使用了游离自体髂前嵴骨移植，14例患者使用了游离自体下颌骨联合骨移植。结果显示，31例患者中有3例腭裂的牙槽-腭区域口鼻交通未成功闭合。40例患者中有3例骨移植的影像学融合未成功。影像学成功与外科医生经验的增加无关。该研究表明，12岁之前进行移植时可获得最佳移植效果。与髂前嵴骨移植的结果相比，下颌骨联合骨移植的影像学结果往往略好。
