年轻女性24个月自然增龄后面部软组织变化的初步探讨

Preliminary study on facial aging changes during 24 months among young females

目的初步探讨年轻女性24个月后面部软组织的变化。方法选择20-25岁的年轻女性20人，24个月前后各进行一次面部软组织激光扫描。使用RapidformXOV软件将20位研究对象2次的面部软组织三维图像进行重叠，得出彩色图像，通过不同颜色显示了24个月后面部软组织的变化。其中绿色、黄色、浅蓝色和浅红色区域为未发生变化的区域，而深蓝色和深红色区域为出现明显变化的区域，蓝色代表负值，红色代表正值。将面部分为眶区、鼻区、唇区、颏区、眶下区、颧区、颊区、腮腺咬肌区、额面区和颞面区。分别记录每个区域的变化情况。结果65％的受试者（13／20）唇区为深蓝色，45％的受试者（9／20）颏区为深蓝色，25％的受试者（5／20）腮腺咬肌区为深蓝色。结论20～25岁的成人女性，24个月面部的增龄性变化可能主要表现在口唇部软组织变薄。

Objective To determine the facial aging changes after 24 months among 20 young females aged 20 to 25 years. Methods Twenty young females were scanned twice before and after 24 months with laser scanning technique. A color map was got by superimposition with Rapidform XOV. The areas of green, yellow, light blue and pale red in the color map meant no change. The other areas of dark blue and deep red standed for decrease and increase respectively. The face was divided into 10 regions according to anatomical features. The changes of color in every region were recorded. Results The lip-region was dark blue in 65% of the subjects. The mental region was dark blue in 45% of the subjects. The parotideomasseteric region was dark blue in 25% subjects. Conclusion The lip region tended to be decreased during 24 months among young females.
