单侧唇裂继发鼻畸形修复新法

目的　矫正单侧唇裂继发鼻畸形。方法　基于对单侧唇裂鼻畸形的病理解剖学研究和对其畸形特征的认识，我们设计一种新的手术修复方法。手术经鼻端和患侧前庭联合切口，解剖、显露双侧鼻翼软骨，同时形成患侧前庭粘膜软骨瓣；在纠正鼻中隔软骨偏曲，松解患侧鼻肌复合体起点，使鼻翼脚无张力抬高后，再通过悬吊技术和粘膜软骨瓣的 Ｖ Ｙ 推进，将患侧鼻翼软骨进行整体旋转复位；最后，应用口轮匝肌上部纤维内收抬高鼻翼脚，用鼻肌复合体起点复位调整鼻孔形态，完成鼻畸形的矫正。结果　自１９９３ 年至今，经９２ 例实践，效果满意。结论　本手术方法具有切口暴露好、可直视操作、安全可靠等特点；患侧鼻翼软骨整体复位具有良好的临床效果。

A new approach for secondary deformities of unilateral cleft lip nose

Objective\ The aim of this work was to correct the secondary deformities of unilateral cleft lip nose. Methods\ On the basis of patho anatomical study and the comprehension on the cleft lip nose, a new approach to correct the secondary deformities of unilateral cleft lip nose was designed and used.During operation, an intranasal and marginal combining incision was made to explore the alar cartilages and to from a mucosal cartilage flap in the nasal vestibule. After the deformity of septal cartilage and the abnormalities of the alar base on the cleft side were repaired, the total alar cartilage was repositioned and rotated with suspension and V Y advancement to correct the nasal deformities.Results\ Since 1993, a total of 92 cases were treated by the above procedure and satisfactory results were obtained. Conclusion The clinical applications showed that there were several advantages for this method, and good results can be gained by repositioning the total alar cartilage on the cleft side.
