Chin dimple removal can be done. The origin of this anatomical variant is due to lack of the mentalis muscle crossing over and leaving a dip. Some others believe that the dimple is due to other soft tissue deficits. Whatever the orgin, one may need to elevate the area and fill it in with fat or some other filler. Because the skin is usually tacked and attached down to the deeper structures, some surgical lifting is necessary. After lifting, you will then need to place some tissue there to keep it elevated and not associated with the skin again. This is where grafts can work and there are many options for that. Fillers are less efficacious in my experience. Chin implants can also serve to make those dimples less apparent as well but may change the way your chin looks in a significant way.
