How is genioplasty performed?Several surgical options exist for the treatment of chin deformities. The two most popular procedures are alloplastic chin implants and sliding genioplasty.
Alloplastic chin implantsAlloplastic implants use materials such as silicone, polytetrafluoroethylene and polyester mesh to alter the shape of the chin. A chin implant can be used for subtle advancements of 5 mm or less and is placed via an incision in the skin below the chin. If used for bigger augmentations, pressure could be placed on the bone it is anchored to, meaning long-term failure. It could also move from its original position as a result of gravity and does comes with risk of infection. As the implant is foreign material, it presents a chance of becoming rejected, therefore many surgeons prefer to use sliding genioplasty.
Sliding genioplastySliding genioplasty (also known as osteotomy) can produce face-transforming results thanks to its versatility. A chin can be lengthened or reduced via the mouth, meaning no external skin scars. Essentially, the bone of the chin is divided in such a way that it slides forwards or backwards to lengthen or shorten the chin and jaw. The bone is then secured using a small titanium plate.
Who can genioplasty benefit?Chin surgery can address a small and deficient chin, can make a shortened face look longer or can reduce a protruding profile. Often, genioplasty will be performed at the same time as cosmetic rhinoplasty to compliment the new shape of the nose and help bring the face into full harmony.
What is the down time?Patients are generally discharged on the same day of the procedure, providing they rest at home. The procedure is performed under general anaesthesia and usually takes around 45 minutes to complete. There is little pain associated with chin augmentation. You should expect for the first week following surgery to see extensive swelling and moderate bruising. As a result of the swelling you may feel the chin looks “boxy” or “square”, but this will gradually smooth out over a period of two to three weeks. Most people feel comfortable going out within a week and you can return to work after five days. The downtime for sliding genioplasty is slightly longer than the downtime for implants.
What aftercare is involved?
An ice pack should be applied to the area regularly during the first 36 hours and your doctor may prescribe an antibiotic to help prevent infection. When sleeping, try to sleep on your back with your head elevated on two pillows for the first two weeks. You will also need to follow a soft diet over this period.
