No matter where the incisions are made, the objective is the same: to remove excess skin and underlying tissues, while in some cases using sutures to tighten the muscles and connective tissue beneath the skin. After removing unwanted material, the surgeon closes the incisions with sutures.
A more modern and less invasive approach utilizes endoscopy to achieve similar results. With this technique, several small incisions are made behind the hairline to accommodate the endoscopic camera and surgical instruments. This method usually results in reduced, less noticeable scarring and a somewhat shorter recovery period.
