Scarring after endoscopic procedures is usually small and heal well. This goes for every kind of endoscopic surgeries compared with the old fashion techniques that created long scars over the chest and abdominal cavity in order to get into the target organ. In ETS there are two scars measuring about 10 mm. These are small and for a patient who is not producing keloids (imperfections of the outer skin that may develop after surgical incision) will not see the scars weeks or months after the operation. Also the cuts are made in very good cosmetic locations. While doing ELS (endoscopic lumbar sympathectomy) there are three incisions on either side of the flank region and they are also relatively small. The incisions are made in skin lines which helps obscure their visibility.
