背景整形外科医生尝试了各种方法来重建唇裂患者上唇的美学亚单位，但大多数情况下效果不理想。我们建议修复鼻唇沟复合体中的3个肌张力线组将具有改善的美学效果。方法对5例正常流产胎儿的鼻唇沟组织进行显微CT扫描，建立鼻唇沟肌肉复合体的三维模型。结果显微CT扫描显示鼻肌、周围肌、上唇提肌和边缘肌的肌纤维之间存在着密切的联系和相互作用。结论根据显微CT扫描的二维图像，提出了鼻唇肌复合体的概念和肌张力线组理论：鼻肌的前壁、降鼻中隔肌、口轮匝肌和提上唇鼻翼肌之间存在着密切的关系。张力线组是鼻唇肌复合体中的3个张力线结构，它们在交叉点处彼此互锁，并保持唇部和鼻部的特定形状和美学。
BackgroundPlastic surgeons have attempted various ways to rebuild the aesthetic subunits of the upper lip in patients with cleft lip with less than perfect results in most cases. We propose that repairing the 3 muscle tension line groups in the nasolabial complex will have improved aesthetic results. MethodsMicro–computed tomographic scans were performed on the nasolabial tissues of 5 normal aborted fetuses and used to construct a 3-dimensional model to study the nasolabial muscle complex structure. ResultsThe micro–computed tomographic (CT) scans showed the close relationship and interaction between the muscle fibers of nasalis, pars peripheralis, levator labii superioris, and pars marginalis. ConclusionsBased on the 2-dimensional images obtained from the micro–computed tomographic scans, we suggest the concept of nasolabial muscle complex and muscle tension line group theory: there is a close relationship among the alar part of the nasalis, depressor septi muscle, orbicularis oris muscle, and levator labii superioris alaeque nasi. The tension line groups are 3 tension line structures in the nasolabial muscle complex that interlock with each other at the intersections and maintain the specific shape and aesthetics of the lip and nose.
