口轮匝肌精细化解剖修复矫正单侧唇裂术后继发畸形

目的 探讨单侧唇裂术后继发畸形功能性修复的方法.方法 采用基于对口轮匝肌的鼻束、鼻唇束、唇束进行精细化的解剖分离和精确复位的综合手术方法矫正单侧唇裂继发畸形.结果 2003年1月至2008年10月,于临床应用96例,术后患者唇、鼻形态和功能均得到明显改善.85例获得随访,时间为3个月至5年,患者满意度达94.1%(80/85例).结论 对口轮匝肌进行精细化解剖、精确复位,是单侧唇裂术后继发畸形获得良好治疗效果的重要保障.

Correction of secondary deformity of unilateral cleft lip with refined anatomic repair in orbicularis oris muscle

Objective To investigate the functional repair of secondary deformity of unilateral cleft lip. Methods The nasal branch, nasolabial branch, and labial branch of orbicularis otis muscle were dissected and repositioned precisely to correct the secondary deformity of unilateral cleft lip. Results 96 patients were treated successfully with this method during Jan. 2005 to Oct. 2008. Good cosmetic and functional results were achieved. 85 cases were followed up for 3 months to 5 years with a satisfactory rate of 94.1% ( 80/85 cases). Conclusions The application of refined anatomy and precise reposition in orbicularis otis muscle is important to ensure therapeutic effect in patients with secondary deformity of unilateral cleft lip.
