Age-related growth changes in the nasolabial region were analyzed through six measurements taken between 1 year and 18 years of age in 1,593 North American Caucasians. By 1 year of age, the length of the cutaneous portion of the upper lip and the width of the nose showed the highest levels of development compared with their adult size, 80.3 and 79.5%, respectively. By 5 years, the developmental level of the nasolabial region except nasal tip protrusion approached their maturation level. Our nasal measurements indicated that growth of the nose between 5 and 18 years was significantly greater than that of the upper lip, which revealed significantly greater growth increments between 1 and 5 years of age. The cutaneous upper lip height reached its adult size in 3-year-old females (12.7 mm) and 6-year-old males (14.4 mm). Nose width and height were fully developed in females by age 12 and in males by age 14 or 15. Rapid growth occurred in the upper lip, nose height, and nasal tip protrusion between the ages of 1 and 4 years. Knowledge of these age-related morphologic variations within the nose and upper lip may be useful in planning the time and type of reconstructive surgery and in anticipating further change in the operated regions after the surgical reconstruction.
通过对1593名北美白种人在1岁至18岁之间进行的六项测量，分析了鼻唇区域与年龄相关的生长变化。到1岁时，上唇皮肤部分的长度和鼻子的宽度与成人尺寸相比显示出最高的发育水平，分别为80.3%和79.5%。到5岁时，除鼻尖突出外，鼻唇区域的发育水平接近成熟水平。我们的鼻部测量表明，5岁至18岁之间鼻子的生长明显大于上唇，而上唇在1岁至5岁之间的生长增量明显更大。3岁女性（12.7毫米）和6岁男性（14.4毫米）的皮肤性上唇高度达到成人尺寸。女性在12岁时鼻子宽度和高度完全发育，男性在14岁或15岁时完全发育。1岁至4岁之间上唇、鼻高和鼻尖突出出现快速生长。了解鼻子和上唇内这些与年龄相关的形态学变化，可能有助于规划重建手术的时间和类型，并预测手术重建后手术区域的进一步变化。
