Ten cadavers were employed to demonstrate the presence of the SMAS in the upper lip using macroscopic and microscopic techniques. The relationships and attachments of the SMAS to the dermis of the upper lip are described. In cadavers, medial traction on the SMAS in the upper lip in conjunction with superolateral traction on the SMAS in the cheek is found to decrease the depth of the nasolabial fold. Superior traction on the SMAS in the upper lip elevates the interlabial line, reestablishes the convexity of the lateral vermilion border, and partially increases concavity of the profile.
使用宏观和微观技术，对10具尸体进行研究，以证明上唇中存在表情肌-皮肤浅肌膜系统（SMAS）。描述了SMAS与上唇真皮之间的关系和附着情况。在尸体中发现，对上唇的SMAS进行内侧牵引并结合对脸颊的SMAS进行上外侧牵引，可减少鼻唇沟的深度。对上唇的SMAS进行向上牵引可抬高唇间线，重建外侧唇红缘的凸度，并部分增加侧面轮廓的凹陷度。
