摘　　要：目的创新单侧唇裂术后唇畸形的整复技术并评价其术后效果。方法单侧唇裂术后唇畸形患者44例纳入研究,按肌肉对称平衡修复理论指导重建口轮匝肌。利用照片测量人中偏斜角以及唇高、侧唇宽、唇峰点红唇厚度、唇峰至面中线距离的不对称率(即健侧/患侧的比值减1的绝对值,其值越小代表健患侧越对称)等指标以评价手术效果。结果44例单侧唇裂术后继发畸形的患者进行唇部整复术后,其人中偏斜角、唇高不对称率及唇峰点红唇厚度不对称率3个指标差异有统计学意义,均为术后小于术前(P<0.05)。结论新的手术方法术后健患侧的对称性较术前有了明显改善,术后短期效果显著,为单侧唇裂术后畸形的整复及口周肌力平衡的恢复,提供了新的思路。Objective Short-term outcome evaluation for the correction of unilateral cleft lip deformity with a new technique.Methods Forty-four patients with unilateral cleft lip deformity were included in the study and in which the orbicularis oris muscle was reconstructed to achieve the optimal force balance of reconstructed orbicularis oris.The photometric two-dimensional indexes,including the philtrum oblique angle and asymmetry ratios(lip height,lip width,vertical distance from the white roll to the vermilion bottom at the Cupid’s bow point,and vertical distance from the Cupid’s bow points to facial midline),were employed to measure and evaluate the outcome.Results Several indexes showed statistically significant difference,and they included the philtrum oblique angle,asymmetry ratio of the lip height,and asymmetry ratio of the vertical distance from the white roll to the vermilion bottom at Cupid’s bow points(P<0.05).Conclusion The results suggested that the new muscle reconstruction technique can significantly improve the shortterm outcome of the correction of unilateral cleft lip deformity.
