目的：探讨对偶三角瓣联合口轮匝肌解剖复位法在单侧面横裂矫正术中的临床应用。方法：回顾性总结2013-2016年运用对偶三角瓣联合口轮匝肌解剖复位法矫正单侧面横裂畸形的12例病例。结果：所有病例获随访6月-3年,静态和动态时口角外形基本与对侧对称。各项指标术前及术后的比较结果表明术后口角对称性得到了良好的恢复。1例患者术后3年复诊,患侧口角与健侧对称。结论：运用对偶三角瓣联合口轮匝肌解剖复位法矫正单侧面横裂可以恢复面横裂患者口角的形态与功能,术后远期效果良好。

英文摘要：

Objective：To investigate the transverse facial cleft repair with symmetric triangular flap and reconstruction of orbicular muscles of mouth.Methods：The clinical data of 12 patients with transverse facial cleft repaired with symmetric triangular flap and reconstruction of orbicular muscles of mouth from 2013 to 2016were collected and retrospectively analyzed.Results：All patients were followed up regularly ranging from 6months to 3years and all of them got the static and dynamic symmetry of oral commissure.The preoperative and postoperative indicators showed that symmetry of commissural had been well restored.One case followed up 3years,asymmetries of form and functional activity of oral commissure was observed.Conclusion：Application of symmetric triangular flap and reconstruction of orbiculary muscles can enhance the morphology of oral commissure and contribute to functional recovering and obtain the long-term improvement of symptoms.
