I would need to read your surgeons operative report to give you the most accurate assessment. However, if your surgeon cut or removed too much muscle from the corrugator complex (muscles that enable you to frown ), that would explain the dents in the glabella area (space between your brows). The upper forehead dents are probable due to soft tissue injury from the instruments used for the endoscopic brow lift. Fixing these problems is possible with facial micro fat grafting. Fat grafting involves harvesting fat with liposuction from another area of your body (usually tummy or thighs), processing the fat, and then injecting it in very small droplets to replace lost volume and correct contour deformities. It often takes more than 1 fat grafting surgery to achieve the highest quality result.
