腭裂患者犁骨发育程度的测量分析

目的：评价腭裂及其修复对犁骨生长发育程度的影响。方法：应用三维 CT 测量的方法测量38例大龄腭裂患者（年龄大于14岁，平均23．4岁）和正常对照组76例（平均22．8岁）的犁骨生长发育程度，选取以下3个指标：犁骨的下缘长度L1，前鼻棘到蝶鞍点的距离 L2，犁骨近似面积 S，将其与正常对照组相比。结果：腭裂患者包括腭裂术前及术后患者其 L1、L2和 S 均小于正常对照组（P ＜0．05）。腭裂术后组（CP1）与腭裂术前组（CP2）相比犁骨面积 S 差异有显著性（P ＝0．014），L1差异无显著性（P ＝0．145），L2差异有显著性（P ＝0．044）。结论：腭裂患者的犁骨发育程度较差，与上颌骨融合程度降低，与鼻中隔软骨、筛骨垂直板之间骨缝长度变短，后者受手术创伤影响较大。

Measurement and evaluation of the vomer development of the patients with cleft palate

Objective:To evaluate the vomer development of cleft palate patients.Methods:38 patients over 1 4 years(averaged 23.4 years)of age with cleft palate and 76 controls of normal people(aged 22.8 year on average)were included.The 3D computed tomo-graphy reconstruction images of the bony nasal septum were measured.The development of the vomer was evaluated by comparing the L1 (the length of the lower edge of the vomer),L2 (the length from nasal spine to the point of the sella)and S (the approximate area of vomer)among deferent groups.Results:The L1 ,L2,and S of cleft palate patients were smaller than those of the controls(P <0. 05).Compared with the postoperative cleft cases,the S and L2 of preoperative cases were bigger(P <0.05).Conclusion:The vomer development is adversely affected by cleft palate.Not only the vomer-palate fusion is lower,but also the sutura between vomer and na-sal septum cartilage and ethmoid bone are short.And the latter is greatly influenced by surgical trauma.
