The contours of your face may be enhanced by a variety of techniques. Chin augmentation (also called genioplasty or mentoplasty) strengthens the appearance of a receding chin by increasing its projection. Chin implants provide a permanent and predictable result. Sometimes fat may be injected into specific areas to restore a more youthful fullness to your face. Treatment with fat injections may need to be repeated to maintain improvement.
The goal of chin augmentation is to improve your profile by creating a better balance between your chin and other facial features. Increasing the projection of your chin will not affect your bite or jaw function.
There are two techniques for adding prominence and contour to your chin. One, performed through an incision inside the mouth, requires moving the chinbone. A more common approach involves insertion of a chin implant. The implant is inserted through incisions inside your mouth or on the underside of your chin. In the latter case, surgery usually leaves only a faint scar that is barely visible underneath the chin.
To permit proper healing following chin augmentation, you may be placed on a liquid diet for a day or two. Your chin may be taped or bandaged.
After a chin augmentation, you will most likely be up and about the same day, but your activities will be restricted. You should be able to return to work within one or two weeks.
