Plastic 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.
Micro-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.
The 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.
Based 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.
整形外科医生尝试了多种方法来重建唇裂患者上唇的美学亚单位，但在大多数情况下效果并不理想。我们提出修复鼻唇复合体中的3组肌肉张力线将改善美学效果。
对5例正常流产胎儿的鼻唇组织进行微型计算机断层扫描，并用于构建三维模型以研究鼻唇肌肉复合体结构。
微型计算机断层扫描（CT）显示了鼻肌、周边部分、上唇提肌和边缘部分的肌纤维之间的密切关系和相互作用。
基于微型计算机断层扫描获得的二维图像，我们提出鼻唇肌肉复合体和肌肉张力线组理论的概念：鼻肌的鼻翼部分、鼻中隔降肌、口轮匝肌和鼻小柱上唇提肌之间存在密切关系。张力线组是鼻唇肌肉复合体中的3种张力线结构，它们在交叉处相互连锁，维持唇和鼻的特定形状和美观。
