Age-related changes in width (cheilion-cheilion) and height (subnasale-stomion) of the upper lip are studied in 2300 healthy Bulgarians, with ages ranging from three days to 102 years, for the needs of cheiloplasty in both surgery and fine arts. As shown by the results, at birth the upper lip in either gender appears to be one of the most developed organs of the human body, continuing to augment in size up to the eighth decade of life. In preschool age it terminates its intensive development, and in the puberty period it fails to exhibit the growth leap characteristic of the organism as a whole. Throughout the period of postnatal ontogeny, with the exception of early infancy, the lip in the male gender remains bigger, with the difference for height being rather markedly expressed during the ninth decade (3, 8 mm), and for width--thereafter (5.24 mm). The conclusion is reached that cheiloplasty may be undertaken regardless of the patient's age, during the early postnatal days inclusive, and the dimensions recorded for the age intervals being examined may serve as standard values.
为了满足外科手术和美术领域唇整形的需求，对2300名年龄在3天至102岁之间的健康保加利亚人上唇宽度（口角间）和高度（鼻下点-口裂点）的年龄相关变化进行了研究。结果表明，出生时，无论男女，上唇似乎都是人体最发达的器官之一，其大小一直增长到生命的第八个十年。在学龄前，它停止了快速发育，在青春期，它没有表现出整个机体典型的生长飞跃。在出生后的个体发育过程中，除了婴儿早期，男性的嘴唇一直较大，在第九个十年中，高度差异相当明显（3.8毫米），宽度差异在那之后较为明显（5.24毫米）。得出的结论是，唇整形手术可以在包括出生后早期在内的任何患者年龄进行，所记录的各检查年龄区间的尺寸可作为标准值。
