肌肉复位术矫正单侧唇裂术后鼻底畸形

Muscles reposition in correction of nasal deformity after unilateral cleft lip

目的探讨单侧唇裂术后鼻底畸形矫正的有效手术方法。方法对2007年8月至2010年8月收治的50例单侧唇裂术后鼻底畸形患者，针对不同的畸形程度，采用鼻底肌肉复位术矫正鼻底畸形，并以肌肉组织充填鼻翼基底，弥补患侧上颌骨发育不足；复位鼻唇肌，以保持两侧肌张力的均衡，恢复鼻翼形态。结果术后50例患者的鼻畸形均得到很大程度的改善，术后移位的鼻小柱回到正常位置，左右鼻翼根部和鼻底宽度基本对称，鼻翼根部畸形、鼻底过宽、鼻小柱偏斜均得到较明显改善。对患者手术前后的相关数据进行统计检验，差异有统计学意义（P〈0．05）。结论单侧唇裂继发鼻畸形的病因复杂，可通过对易位的鼻孔压肌翼部、降鼻中隔肌复位术，有效地改善畸形。

Objective To investigate the effective method for correction of nasal deformity after unilateral cleft lip. Methods 50 cases with secondary nasal deformity after unilateral cleft lip were retrospectively analyzed. All the patJets underwent nasal and lip muscle reposition operation to restore the symmetry of nasal alar. Results The nasal deformity was greatly improved in all the 50 cases. The malpostition of nasal column and nasal alar was corrected. The symmetry was markedly improved. The measurement before and after operation showed significant difference （ P 〈 0. 05 ）. Conclusions The reasons of secondary nasal deformity after unilateral cleft lip are complicated. The muscle reposition operation can effectively improve the deformity.
