鼻翼软骨肌肉环在单侧重度唇裂鼻畸形矫正术中的作用

目的:探讨鼻翼软骨肌肉环在单侧重度唇裂术后鼻畸形整复中的作用。方法:经鼻小柱基底的“V—Y”型切口行患侧鼻翼软骨肌肉环修复,对裂侧上颌骨退缩明显者,在裂侧梨状孔边缘处充填自体肋软骨组织,整复76例唇裂鼻畸形患者,观察近、远期效果。结果:76例切口均一期愈合,随访12~38个月,对唇裂鼻畸形患者的鼻尖、鼻翼、鼻孔及鼻小柱畸形矫治术后外形满意。结论:唇裂患者因鼻翼软骨肌肉环发育不良,进而导致了鼻部肌力的失衡。因此,唇裂鼻畸形矫正中修复鼻翼软骨环肌肉状结构具有重要意义。

Alar cartilage-muscle rings in repairing the unilateral severe cleft lip

Objective: To discuss an effective method of cheiloplasty for postoperative nasal deformity after unilateral severe cleft lip.Methods: Seventy-six patients with secondary cleft lip nasal deformity were repaired with alar cartilage-muscle rings by remov al of the points of theattachment of the nasal columella basement through a "V-Y" incision andimplant ation of an autologous rib cartilage tissue around the piriform aperture The short-and long-term responses were observed.Results: All got primary healings.Followed up for 12-38 months,the apex of nose,nasal ala,nostrils and nasal columella produced satisfied outlines.Conclusions: Alar cartilage-muscle ring is hypoplastic,which results in nasal myosthenic disequilibrium.Reconstruction of the alar cartilage-muscle ring plays a key role in the correction of nasal deformities for cleft lip patients.
