Lipomas, Osteomas, non – resorbing Fillers and other lesions may show on the forehead or cheek and appear as lumps. The traditional way of removing such lesions is through an incision in the external skin, which leaves behind a scar. The endoscopic method first described by Dr. Gassner allows to remove forehead lesions without a visible scar. The incision line is placed in the hair bearing skin behind the hairline. For cheek lesions, the incision is placed through the mouth in the gum line.
