The nasolabial fold (NLF), commonly known as “smile line” or “laugh line”, begins at the alar groove and alar facial crease and runs down the lateral aspects of the upper lip [1, 2]. The NLF is one of the most noticeable signs of facial aging [3]. Young individuals having deep NLFs tend to consider themselves to look older than their age.

The nasolabial fold (NLF) is the bulging fat pad and skin lateral to the NLC. The malar fat pad is the triangular fat pad with its base along the NLC and, in young people, its apex along the body of the zygoma.

NLF in Medical typically refers to Nasolabial Fold, the skin folds that run from the side of the nose to the corners of the mouth, often associated with facial aging. These folds are significant in cosmetic procedures and discussions of facial aesthetics. Explore categories such as Cosmetic Surgery and Anatomy for more information.

NLF, MF, IOF, and UEF are habitual primary folds induced by morphological changes in the underlying SMAS architecture. The secondary, accidental creases (DTFC) are cutaneous depressions derived from interacting dermal‐skeletal‐muscular changes …

May 1, 2018 · The NLF is an anatomical landmark and boundary between the cheek and the upper lip and between the type I and type II SMAS (Mitz and Peyronie, 1976, Wang and Huang, 2011).

The use of Nasolabial flap (NLF) to reconstruct orofacial soft tissue defects is one of the oldest methods for reconstruction in the medical literature. Despite widespread use of this invaluable flap, there are still controversies over the terms ...

The novel insights into the 3D anatomy of the FMM related to NLF may help understand the formation of the NLF. Finally, the results of this study may help improve rejuvenation surgery of the NLF in the near future.

The orientation, depth and direction of the NLF movement during smiling are a major predictor of paralysis severity and patients’ quality of life (QOL). 3 Anatomically, the NLFs are facial crease lines or rhytids made visible by shadow formation at the junctions of the upper lip, cheek and nasal alar on either side of the face. 4–6 With age ...

Aug 4, 2020 · The aim of this study was to clarify the heights and spatial relationships of the facial muscles acting on the nasolabial fold (NLF) by dissection and three-dimensional microcomputed tomography for use in aesthetic treatments. This study …

In this article, all terms related to nasolabial flap are explained. II. Anatomy. The Anatomy of the nasolabial region is complex. Nasolabial crease run obliquely from approximately 1 cm superior to the lateral alar rim to approximately 1 cm lateral to the corner of the mouth.
