摘　　要：目的 :比较改良牙支持式上颌骨前部牵引成骨术(anterior maxillary segmental distraction osteogenesis,AMSDO)及上颌骨Le Fort I型截骨术对唇腭裂(cleft lip palate,CLP)患者腭咽部结构的影响。方法:选择32例唇腭裂继发上颌骨发育不足患者,分为AMSDO组(16例)和上颌骨Le Fort I型截骨术组(16例)。治疗前(T1)和治疗后6个月(T2)拍摄头颅定位侧位片,对腭咽部结构进行测量。采用SPSS 12.0软件包对数据进行统计学分析。结果:AMSDO组治疗前、后腭咽部结构测量参数变化无显著差异,Le Fort I型组咽腔深度平均增加3.13 mm、软硬腭交角增加4.3°,腭咽闭合需值(need ratio)平均值大于术前0.11,差异有统计学意义(P<0.05)。结论:AMSDO对腭咽部结构的影响微小,腭咽闭合基本无变化。Le Fort I组术后结果提示可能造成腭咽闭合功能恶化及腭咽部结构适应性代偿。PURPOSE: To compare the effect of anterior maxillary segmental distraction osteogenesis(AMSDO) and Le Fort I osteotomy on velopharyngeal structure in cleft lip palate(CLP) patients. METHODS: Thirty-two patients with CLP were divided into AMSDO group(n=16) and Le Fort I osteotomy group(n=16). Lateral cephalograms were taken before,and 6 months after treatment for analysis of velopharyngeal structure changes. SPSS 12.0 software package was used to compare the pre-and post-operative changes. RESULTS: No significant difference was found in AMSDO group;In Le Fort I osteotomy group, pharyngeal depth, velar angle and need ratio were found significantly different with an average increase of 3.13 mm, 4.3° and 0.11, respectively(P <0.05). CONCLUSIONS: AMSDO has minimal effect on velopharyngeal structure. Results in Le Fort I group suggest possible deterioration of velopharyngeal function and adaptive compensation of the velopharyngeal structure.
