Age-dependent changes in the width and height of the upper lip were studied in 2,300 healthy Bulgarians aged from 3 days to 102 years, for the purposes of cheiloplasty in surgery and of visual art. It has been established that at the moment of birth, the upper lip is one of the most developed organs of the human body in both sexes and that it grows in size up to the age of 80 years, completing its intensive growth during the pre-school age while in the years of puberty it does not show the growth jump characteristic of the organism as a whole. In the males, the lip remains larger during the whole period of postnatal ontogenesis except for the early childhood; the difference in the height is most expressed (3.08 mm) in the 9th decade, and in the width (5.24 mm) even later. The conclusion has been drawn that cheiloplasty can be performed at any age including the first days after birth, the dimensions obtained at the age intervals under study serving as standards.
为了外科唇成形术和视觉艺术的目的，对2300名年龄从3天到102岁的健康保加利亚人上唇的宽度和高度随年龄的变化进行了研究。已确定在出生时，上唇是男女两性人体中发育最完善的器官之一，并且其大小一直增长到80岁，在学龄前完成其快速生长，而在青春期期间它没有表现出整个机体特有的生长跳跃。在男性中，除幼儿期外，在出生后个体发育的整个时期嘴唇都保持较大；高度差异在第9个十年中最为明显（3.08毫米），宽度差异（5.24毫米）甚至更晚才出现。得出的结论是，唇成形术可以在任何年龄进行，包括出生后的头几天，在所研究的年龄间隔所获得的尺寸可作为标准。
