【摘要】 目的探讨改良Onizuka法修复单侧唇裂的效果。方法采用改良Onizuka法修复24例单侧唇裂,将旋转瓣止于鼻小柱基底中点,在推进瓣的唇红缘上方形成小三角瓣插入到裂隙近中侧唇峰上方。沿鼻小柱基底线去除C瓣的皮肤,将C瓣的肌层向外侧旋转与裂隙侧鼻翼基底缝合加强鼻堤。推进瓣前端形成与鼻小柱基底相吻合的切口,隐蔽鼻底切口线。结果裂隙侧唇峰高度恢复理想,鼻底宽度与健侧相等。术后随访显示三角瓣无明显瘢痕,人中嵴形态协调。结论改良Onizuka法修复单侧唇裂可以充分降低唇峰,不会破坏人中嵴形态的协调性,并且鼻底切口瘢痕隐蔽,是一种易于掌握的有效方法。更多还原

【Abstract】 Objective To explore the surgical technique of a modified Onizuka cheiloplasty for repairing the unila-teral cleft lip.Methods 24 patients with unilateral cleft lip were repaired by modified Onizuka cheiloplasty.The rota-tion flap ended at the midpoint of nasal columella crease.A small triangle skin flap was formed above the vermilion border of the advancement flap.The small triangle flap was inserted to the medial side after the Cupid’s bow was built.The skin of the flap C was denuded along the nasal columella crease and the muscle was sutured to the alar base for augmentation of nostril floor on the cleft side.The tip of the advancement flap was sutured at the midpoint of nasal columella crease and the skin of nasal floor was trimmed to hide the incision line around the nasal columella base.Results It was found that the Cupid’s bow was rebuilt in a natural form and the configuration of the upper lip was reconstructed symmetrically.The long term follow up studies showed that the philtrum column was not disturbed by the small triangle flap and the nasal floor was rebuilt without obvious scars.Conclusion The modified Onizuka cheiloplasty is an easy learning technique and efficient for repairing the unilateral cleft lip.This technique can satisfy the patients by reducing the length of scar as well as rebuilding a natural form of upper lip and nostril floor.更多还原
