摘要
目的:探索髂骨移植修复齿槽裂和上颌发育不足的效果。方法:采用髂骨移植修复39例齿槽裂,并对其进行手术前后头影测量和统计学分析。结果:齿醒有临床成功率85%,SNA有术前平均值为75.8±2.3。术后为78.4±1.6,两者差异具有显著性(P〈0.05),显示上颌骨凹陷或平塌有明显的改善。SNA角与SNB角之比手术前后亦有明显的差异(P〈0.05),术后两者之比明显趋于正常。结论自体髂骨移植修复齿槽裂不但可以封闭口-鼻腔裂隙,而且还可以改善上颌骨前份发育不足所致的审美缺陷.
Objective:To study the effeetion of alveolar cleft and hypoplasia of anterior maxilla re paired with iliac bone grafting.Methods:39cases were repaired with autogenous lilac bone grafting and e-valuated by cephalometric radiography pre--and postoperafion(one year or SO)Results:The overall clinical successful rare of bone grafting was 85,the average value of SNA angle 758±23 before operation and 78.4±1.6 after operation(P<0.05)which indicated that the defect of maxilla obviously improved.the comparison of SNA and SNB was different between before and after operations(P<0.05)which showed to trend norma1.Conclusion;The alveolar cleft repaired w ith autogenous iliac bone grafting Call not only dose the oral—nase cleft but call improve the defect of m axd]a that provide the base of or—thognathic surgery and deuture prosthetic.
