Abstract
目的 探索使用Abbe唇瓣矫正单侧唇裂修复后上唇过紧、唇弓、唇珠不明显和上唇位居下唇后方等畸形的效果.方法在上唇下正中部红唇上方的皮肤几毫米处由上向下切开唇正中全层,并使其向两侧自然移动,其间隙的大小应与缺如的唇珠宽度的距离相等,然后在下唇正中依缺损的幅度画出下唇Abbe唇瓣的大小.一般Abbe唇瓣的宽度为8 mm,长度为下唇的红唇加2~3 mm的白唇在内.依切口线切开唇瓣,以唇动脉为蒂旋转180°插入上唇正中缺损区后,按黏膜、肌层及皮肤分别进行缝合.10 d后Ⅱ期断蒂,修整红唇缘.结果42例受术者均显示了明显的人中嵴、人中凹、唇峰、唇珠和上唇的正常高度和宽度,同时上唇鼻底的瘢痕不明显,恢复了上下唇前后的正常和谐关系.结论使用Abbe唇瓣重建缺损的上唇唇珠及人中后,上唇形态接近自然。
