摘　　要：目的评估肌肉力矩平衡重建技术联合鼻内固定术矫正单侧唇裂术后继发鼻唇畸形的远期效果,为进一步改善唇裂继发鼻唇畸形手术治疗效果提供依据。方法选取40例单侧唇裂继发鼻畸形接受肌肉力矩平衡重建技术联合鼻内固定术方法修复二期鼻畸形的患者为研究对象,患者年龄4~28岁。收集所有患者术前、术后即刻(术后7 d)、术后1年鼻部仰面二维照片,比较患者术前、术后即刻、术后1年鼻部对称性变化。结果力矩平衡肌肉重建技术术后即刻鼻小柱偏斜角、鼻孔高度比、鼻翼切线角、鼻翼切线角比、鼻孔长宽比大于术前,鼻底宽度比、鼻孔宽度比小于术前(P<0.01)。力矩平衡肌肉重建技术术后即刻与术后1年相比,鼻底宽度比、鼻孔高度比和鼻孔长宽比的差异无统计学意义(P>0.05)。结论肌肉力矩平衡重建技术联合鼻内固定术对单侧继发鼻唇畸形修复效果显著,可以获得较稳定的术后1年手术修复效果。Objective The long-term effect of muscular force balance reconstruction technique combined with intranasal fixation for correcting secondary nasolabial deformity after unilateral cleft lip was evaluated.The aim was to provide a basis for further improving the surgical treatment effect of secondary nasolabial deformity of acleft lip.Methods A total of 40 patients aged 4-28 years with secondary nasal deformity and unilateral cleft lip were selected as research subjects.The two-dimensional photo measurement analysis method was used in comparing the surgical results before and immediately after the operation(7 d)and 1 year after the operation.Results Columellar angle,nostril height ratio(NHR),alar rim angle,alar rim angle ratio,and nostril shape(NS)increased dimmediately after the operation,whereas alar base width ratio(ABWR)and nostril width ratio decreased(NHR)immediately after the operation(P<0.01).The ABWR,NHR,and NS immediately after the operation were not significantly different from those 1 year after the operation(P>0.05).Conclusion Muscular force balance reconstruction technique combined with intranasal fixation is effective in the repair of unilateral secondary nasolabial deformity,and stable results can be obtained 1 year after surgery.
