Nasolabial Fold Correction: Surgery Introduction
The nasolabial fold is a surface landmark that separates the cheek and jaw areas. It represents a secondary excess of skin folds, commonly referred to as two sides of the "facial danger triangle." The nasolabial fold also plays a crucial role in facial expressions. Present from birth, it accompanies a person throughout their life. Over time, the nasolabial fold undergoes changes from shallow to deep, narrow to wide, and short to long. Its formation results from the interaction between dynamic and non-dynamic tissues of the cheek area.
Many facial expressions, such as smiling and crying, are initiated through changes in the shape of the nasolabial fold. For instance, smiling starts with the muscles around the nasolabial fold contracting, pulling the upper lip backward toward the nasolabial fold. Due to the thick subcutaneous fat in the cheek area, resistance is encountered at the nasolabial fold, causing it to curve and deepen. Similarly, during expressions like crying, showing teeth, or chewing, the nasolabial fold bends and deepens accordingly.
In youth, changes in facial expressions and the nasolabial fold's form give a natural and harmonious impression both in motion and at rest. However, after the age of 30, signs of facial aging become more apparent, particularly the deepening of the nasolabial fold. This is due to the sagging and accumulation of facial skin on the cheek side of the nasolabial fold, compounded by decades of frequent activity in this area. As a result, even at rest, the nasolabial fold gradually deepens, widens, and elongates. These changes are even more pronounced during various facial expressions, causing distress to those who value beauty. Consequently, many seek various cosmetic procedures, prompting beauty professionals to explore different solutions, such as facelifts, fillers, and laser treatments for the lower face. In terms of effectiveness, combining facelifts with filler treatments yields the most ideal results in reducing and smoothing the nasolabial fold.
