MDAuthor Information From the Section of Plastic and Reconstructive Surgery. Department of Surgery, Dartmouth-Hitchcock Medical Center, Lebanon, NH. Annals of Plastic Surgery: July 1992 - Volume 29 - Issue 1 - p 23-30 Buy Abstract 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 rhino-plasty. 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.
