Aesthetic units of the face have been previously described. The lip itself may be divided into smaller topographic subunits. The lateral subunit is bordered by philtrum column, nostril sill, alar base, and nasolabial crease, while the medial topographic subunit is one-half the philtrum. When a large part of a subunit has been lost, replacing the entire subunit rather than simply patching the defect often gives a superior result. The only tissue suitable for the aesthetic restoration of moderate-sized defects of the upper lip is lower lip. An exact pattern is outlined and an Abbé flap is taken from the midline of the lower lip and transferred in two stages. Like tissue is replaced in kind, border scars are positioned aesthetically, and the orbicularis sphincter is reconstituted with an intact symmetrical commissure, muscular modiolus, and upper and lower lip symmetry. Spontaneous reinnervation by appropriate segmental facial branches occurs within 1 year. Four patients are presented.
面部美学单位此前已有描述。唇部本身可进一步细分为更小的局部亚单位。外侧亚单位以人中嵴、鼻槛、鼻翼基部和鼻唇沟为界，而内侧局部亚单位为人中的一半。当一个亚单位的大部分缺失时，替换整个亚单位而非简单修补缺损通常能取得更好的效果。适合对上唇中等大小缺损进行美学修复的唯一组织是下唇。勾勒出精确的图案，从下唇中线取一块阿贝瓣并分两期转移。用同类组织进行替换，将边缘瘢痕置于美观位置，通过完整对称的口角、肌核以及上下唇对称性来重建口轮匝肌。合适的面部节段性分支会在1年内自发进行再支配。本文展示了4例患者。
