The nasolabial folds are the folds around the mouth. These folds are made up of fat, skin, connective tissue and some muscle. They are the continuation of the marionette lines from below and are due to the same reasons that marionette lines form. The nasolabial folds are the folds that are superior to the corners of the mouth. While the folds below the corners of the mouth are considered marionette lines. They are brought on by a few sources.
With age you lose important volume in your face. This causes the tissues to descend downward or droop. There is also a movement inward with the volume loss. The loss of volume in the cheeks, jaws, and mouth area all contribute to the nasolabial folds getting deeper with age. Another reason for the formation of the nasolabial folds are from the loosening of ligaments within the face which can cause the tissues of the face to sag. Sometimes the nasolabial fold is so heavy that surgery, fillers, and lasers won't solve it. Only excision solves the problem. The scar is expertly placed in a natural appearing skin crease and virtually impossible to see. The amount of skin removed depends upon Dr Mirmanesh's evaluation, the patient's goals and the laxity of the skin. The underlying muscle is not disturbed. The incision is meticulously closed to hide the scar.
