GPL Chin Surgery
Procedure The chin can be enhanced or reduced by moving and fixing the chin bone (=sliding genioplasty or mentoplasty). Enhancement can also be achieved with a chin implant. A small localised prominence can be removed with a burr. 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 and for removal of a localised prominence. If the bite is affected, a dental opinion should be sought prior to aesthetic correction. This operation is sometimes combined with a rhinoplasty to achieve more balance. I do not use drains routinely. The wounds are repaired with sutures under the skin which do not 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 (sliding genioplasty). Underneath the chin for implants and removal of localised prominences.
Operation time 1.5 hours for chin implants, 3 hours for sliding genioplasty
Anaesthesia General for sliding genioplasty and reduction of localised prominences. Local for implants.

Risk factors Smoking / contraception / flights within 6 weeks of surgery, overweight, high blood pressure, bleeding tendency (Stop herbal products or supplements for two weeks before surgery), diabetes, poor oral hygiene
Optimising factors Diet rich in Vitamin C and protein, plenty of fluids, fresh air, scar massage, sun protection
Discomfort 1 - 2 weeks
Bruising 2 - 3 weeks
Recovery Light activities 2 weeks, Driving 3 weeks, Physical work & sports 6 weeks
Acceptable appearance 2 - 4 weeks for most patients (This is subjective)
Final result 6 - 18 months
Alternatives No Surgery, Make-up, Fillers, Fat transfer, dental or maxillofacial treatment if the bite is affected; an alternative to sliding genioplasty is burring through a cut under the chin, which can flatten the chin and make it droopy
