What exactly is an endoscopic browlift and how is it different from a regular brow lift or forehead lift?
An endoscopic browlift (or endoscopic forehead lift) is performed through five small incisions hidden behind the hairline. Using a special sterile telescope called an endoscope, the surgeon can carefully identify and release the muscles which pull your brow down excessively. With an endoscopic browlift you can usually expect 3-5mm of elevation of the brow. The major advantage of the endoscopic approach is the small incisions and less post-operative numbness. If you need more elevation of the brow, an open technique may be better for you. The open forehead lift uses an incision hidden behind the hairline that extends from ear to ear (coronal incision), an incision hidden at the front of the hairline (pre-trichal incision) or a wavy, zigzag incision hidden in the fine hair of the hairline (trichophytic incision). Your incision may also be a modification that combines one or more of these types of incisions. The advantage of an open forehead lift is that it can give more elevation of the brow than the endoscopic technique, often 5mm to 1cm of elevation. The principle disadvantage of the open technique is a longer period of numbness of the scalp after surgery and sometimes some permanent numbness of the scalp.
