Objectives: This study aimed to compare the postoperative outcome of the new and classical muscular reconstruction technique combined with nasal internal-fixation method for secondary deformity post unilateral cleft lip repair. A rationale is provided for the further surgical improvement of secondary deformities.
Methods: Sixty patients aged 4-18 years with secondary unilateral cleft lip-nose deformity were involved in this research. The deformities of 28 patients were repaired using the muscular force balance technique through nasal internal fixation method, and 32 were repaired using classical muscular reconstruction technique. Two-dimensional analysis was used to evaluate the nose-lip morphology of pre- and post-operative patients through standardized photographs seven days after surgery.
Results: Compared with preoperative nasal morphology in the muscular force balance technique group, the 7-days postoperative results of this group showed the significantly improved short-term outcomes in the correction of columellar deflection, alar rim angle, nasal shape, and the symmetry of alar base width, nostril width, nostril height, alar rim angle (P<0.05).
Conclusions: The new muscular reconstruction technique with nasal internal-fixation method has a significant effect on nasal repair.
目的: 通过比较创新和传统两种肌肉重建技术联合鼻内固定术修复单侧继发鼻唇畸形术后短期鼻部对称性评估效果，为进一步改进唇裂二期手术治疗提供依据。方法: 选取60例单侧唇裂继发鼻唇畸形患者，年龄4~18岁，采用创新肌肉重建技术联合鼻内固定术修复28例，传统肌肉重建技术联合鼻内固定术修复32例，使用二维照片测量分析法，对比术前和术后7 d的短期效果。结果: 术后7 d，力矩平衡肌肉重建组相比于术前在鼻小柱偏斜角、裂隙侧的鼻翼切线角、鼻翼缘立体性有较好恢复，鼻底对称性、鼻孔宽度对称性、鼻孔高度对称性、鼻翼切线角对称性和鼻孔形状也有较大改善（P<0.05）。结论: 新肌肉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。.
