目的 三维分析成年期前未行腭裂修复术的单侧完全性唇腭裂(UCLP)患者的鼻上颌复合体形态对称性.方法 对9例2.5岁前完成唇裂修复术、成年前未行腭裂修复术的UCLP患者进行螺旋CT扫描、三维重建,选择22个头颅标志点进行定点测量,分析鼻上颌复合体的三维形态.结果 成年前未行腭裂修复术UCLP患者裂侧NC-HP、PF-MSP距离分别为18.01mm、19.72mm,大于健侧13.35mm、17.31mm(P＜0.05);裂侧NC-CP、U3-HP距离分别为59.64mm、39.55mm,小于健侧64.13mm、39.70mm(P＜0.05),即裂侧鼻腔较健侧明显下凹和塌陷,裂侧后段硬腭宽度大于健侧,尖牙低位.正中结构存在偏移,鸡冠点、鼻中隔、上中切牙中点偏向裂侧,骨性前鼻棘点朝向健侧.结论 成年前未行腭裂修复术的UCLP患者颅面不对称主要集中在鼻腔和邻近裂隙的牙齿槽区,颅面上部和远离裂区的区域没有明显不对称.
目的 三維分析成年期前未行腭裂脩複術的單側完全性脣腭裂(UCLP)患者的鼻上頜複閤體形態對稱性.方法 對9例2.5歲前完成脣裂脩複術、成年前未行腭裂脩複術的UCLP患者進行螺鏇CT掃描、三維重建,選擇22箇頭顱標誌點進行定點測量,分析鼻上頜複閤體的三維形態.結果 成年前未行腭裂脩複術UCLP患者裂側NC-HP、PF-MSP距離分彆為18.01mm、19.72mm,大于健側13.35mm、17.31mm(P＜0.05);裂側NC-CP、U3-HP距離分彆為59.64mm、39.55mm,小于健側64.13mm、39.70mm(P＜0.05),即裂側鼻腔較健側明顯下凹和塌陷,裂側後段硬腭寬度大于健側,尖牙低位.正中結構存在偏移,鷄冠點、鼻中隔、上中切牙中點偏嚮裂側,骨性前鼻棘點朝嚮健側.結論 成年前未行腭裂脩複術的UCLP患者顱麵不對稱主要集中在鼻腔和鄰近裂隙的牙齒槽區,顱麵上部和遠離裂區的區域沒有明顯不對稱.

Objective To evaluate the symmetry of naso-maxillary complex in patients with unilateral complete cleft lip and palate with no palatoplasty history before 17 years old.Methods 9 patients (4 males and 5 females) with unilateral complete cleft lip and palate (UCLP) were selected.They all underwent lip repair before 2.5 years old and had no history of palatoplasty before 17 years.They received spiral CT scan and 3D reconstruction of their naso-maxillary complex.22 variables were measured in the reconstructed images and the symmetry of the complex were analyzed.Results The distances of NC-HP and PF-MSP in cleft side were 18.01 mm and 19.72 mm,which were 13.35 mm and 17.31 mm bigger than that in the noncleft side(P＜0.05).The distances of NC-CP and U3-HP in cleft side were 59.64 mm and 39.55 mm,which were 64.13 mm and 39.70 mm shorter than that in the non-cleft side (P＜0.05).The measurements showed a collapsed and sunken nasal cavity,a wider posterior hard palate and elevated canine in cleft side.There were also deviations of the middle structures.Crista galli,nasal septum,and the mid-point of upper central incisors deviated to cleft side,while skeletal anterior nasal spine deviated to noncleft side.Conclusions Most asymmetries are found in nasal cavity and the dentoalveolar area near the cleft.No significant asymmetry is found in upper cranialfacial strutures,nor in regions not in the adjacency of the cleft.
