目的评估运用黏膜瓣Z成形术矫正鼻翼塌陷的治疗效果。方法 2011年12月至2013年6月,对46例二期单侧唇裂患者使用黏膜瓣Z成形术锁边,缝合大翼软骨和侧鼻软骨来矫正其鼻翼畸形。测量鼻小柱倾斜度和鼻孔宽度,并进行统计分析。结果患侧鼻孔的宽度、鼻小柱的倾斜度及鼻尖和鼻翼的对称性都有明显改善。41例患者术后随访6个月,3例患者出现了轻度复发,但其数据分析与术前比较仍有明显改善。结论黏膜瓣Z成形术可有效矫正单侧唇裂患者的鼻翼塌陷。

Objective To evaluate the effectiveness of mucochondrial Z plasty in correcting the collapse of lower lateral cartilage in the ala and nostril shaping. Methods From Dec. 2011 to Jun. 2013, 46 patients with unilateral cleft lip and nasal deformities were admitted for a secondary rhinoplasty. All the patients were treated with mucochondrial Z-plasty plus locking stitch suture of greater alar cartilage and lateral nasal cartilage to correct the ala and nostril deformities. The width of nostril and the inclination of columella were measured and analyzed. Results The width of nostrils, the inclination of the columella and the symmetry of the nasal tip and ala were all improved significantly after the surgery. Forty-one patients were followed up for 6 months, mild recurrence were observed only in 3 patients, while their data were still much better than that of preoperation. Conclusion The mucochondrial Z-plasty can effectively correct the ala and nostril deformities of patients with unilateral cleft lip.
