英语语法分析

The ideal function and figure of nasolabial region could be achieved in our clinical experience.

该术式在临床应用上获得了较满意的功能及形态的结果。

Nasolabial angle only reflected change of upper lip, but could not reflect characters of facial profile.

鼻唇角只能反映上唇本身的形态变化，不能直接反映面部侧貌的特征。

This creates "nasolabial folds, " lines that extend from the tip of the nose to the corners of the lips: the parentheses of the face.

于是，从鼻尖一直延伸到嘴角的“鼻唇间纹"便诞生了：看起来像括弧。
