Procedure A chin can be enhanced or reduced by moving and fixing the chin bone (=sliding genioplasty or mentoplasty). Enhancement can also be done with a chin implant. A sliding genioplasty involves a cut inside the lower lip, through the chin bone to move the chin and fixation with metalwork. The skin incision is under the chin for implant insertion.
If the bite is affected, a dental opinion should be sought prior to cosmetic correction.
This operation is sometimes combined with a rhinoplasty to achieve more balance.
I don’t use drains routinely. The wounds are repaired with sutures under the skin which don’t require removal and dissolve within four months. Soft food and mouth wash are advisable for one week after sliding genioplasty.
Scars Inner lower lip for bone surgery. Underneath the chin for implants
