【摘要】 目的 :探讨单侧唇腭裂修复术对上颌骨及面部软组织发育的影响。方法 :对不同年龄手术的单侧完全性唇腭裂患者进行了标准头颅侧位片测量 ,并与同年龄正常儿童的各项指标分别进行比较。结果 :正常对照组与病例组在腭平面长度、腭腔深度、前上半面高、腭平面倾斜角和SNA角等 5项测量值上有显著性差异 ;正常对照组在腭平面长度与后上半面高的比值、腭腔深度与后上半面高的比值这 2项上大于病例组 ,两者间有显著性差异 ;在后面部高与前面部高的比值、下颌升支与前面部高的比值和前面部高与前颅底的比值这 3项上 ,病例组大于对照组 ,两者间有显著性差异。结论 :单侧完全性唇腭裂患者以上颌骨长度发育障碍为主 ,这主要是由于先天性发育畸形所致 ,与手术的早、晚无显著相关性。为了使腭裂患儿获得较好的发音功能 ,主张早期行腭裂修复术。更多还原

【Abstract】 Objective:The effect of unilateral cleft lip and palate prothesis on the development of maxillary and facial soft tissue was investigated. Methods: The standard cephalometric measurement was used in patients with complete unilateral cleft lip and palate operated in different periods. We obtained data by measurement. Results: Hard tissue: ANS_X, PNS_X and N_ANS in the group of patients were statistically different from those of the normal control group, but in ANS_PNS and N_PO, there is no statistical difference in these two groups. Angles of hard tissue: There is statistical difference in <N.W.ANS and <SNA between the control and the group of patients. There is only statistical difference in <SNB between the D group and the control group. There is no difference among other groups. Ratios of hard tissue: The ratios of ANS_X/S_X and PNS_X/S_x in the control group were higher than those of the group of patients, and the ratios of S_Go/N_Po, Ar_Go/ N_Po and N_Po/AN in the group of patients were higher than those of the control group. The ratio of NMC/SUBN: It is the highest ratio in the control group, and there is no difference between ratios in the control group and the C group, but there is statistical difference between the control and other patient groups (P<0 05). Conclusion:Comparing with normal persons, the defect of maxillary length development is apparent in the patients with complete unilateral cleft lip and palate due to congenital development deformity. The figure of soft tissue in patients with unilateral cleft lip and palate is anastomotic with the figure of their hard tissue. The excavation of bony middle 1/3 in face results in paramorphia of soft tissue adhering on the bony tissue. We can conclude that in order to obtain better articulation function, the palatoplasty should be carried out early.更多还原
