An acute nasolabial angle and a prominent nasolabial fold are two features that are often associated in the aging face. A new technique is presented that simultaneously addresses both of these features. Levator alae (levator labii superioris alaeque nasi) muscle resection, performed through a subciliary incision, improves the acute nasolabial angle without concomitant rhinoplasty. At the same time, levator alae muscle resection softens the medial nasolabial fold. Partial levator labii superioris muscle resection has occasionally been added to further weaken the middle nasolabial fold. Fresh cadaver dissections were performed to define the anatomy and to plan the surgical approach. This report describes a series of 10 patients who underwent this procedure, with improvement of the acute nasolabial angle and softening of the medial nasolabial fold.
锐角鼻唇角和明显的鼻唇沟是衰老面部常出现的两个特征。本文介绍了一种可同时解决这两个特征的新技术。通过睑缘下切口进行提上唇鼻翼肌（提上唇鼻翼肌）切除术，无需同期行鼻整形术即可改善锐角鼻唇角。同时，提上唇鼻翼肌切除术可使鼻唇沟内侧变浅。偶尔会加做部分提上唇肌切除术以进一步减轻鼻唇沟中部的深度。进行了新鲜尸体解剖以明确解剖结构并规划手术入路。本报告描述了一组接受该手术的10例患者，其锐角鼻唇角得到改善，鼻唇沟内侧变浅。
