Introduction:
Understanding how genioplasty is performed and what to expect during recovery can help patients better understand what to expect when considering treatment.
In the second part of our Genioplasty Q&A series, Professor Ilankovan answer common questions asked about surgical techniques, recovery times, swelling, numbness, and returning to normal activities after surgery.
If you haven’t already read it, you can start with Genioplasty Q&A (Part 1): What is genioplasty and who is it for?
What’s the difference between a sliding genioplasty, box genioplasty, and a chin implant?
Sliding genioplasty involves repositioning a larger segment of the lower jaw, including the symphysis (the central part of the chin) and the parasymphysis (the areas of bone immediately either side of the chin).
Box genioplasty can achieve similar outcomes while avoiding some of the risks associated with sliding genioplasty, including a high risk of lip numbness and possible step deformity (a small ridge or irregularity where the repositioned bone meets the remaining jawbone).
A chin implant works differently, as it increases chin projection using an implant rather than repositioning bone. While effective in some cases, implants carry risks such as infection and, in the longer term, potential damage to the jawbone.
How is genioplasty performed?
In both sliding and box genioplasty, the incision is made inside the mouth to access the chin bone.
A bone cut is made and the segment is repositioned to increase or reduce projection, depending on the planned outcome. The bone is then stabilised using a 1.3mm titanium plate and three or four screws.
For chin implants, the implant is placed either through an incision inside the mouth or through a small incision beneath the chin. The incision is closed with sutures.
Will there be visible scarring?
There is no visible external scar following sliding or box genioplasty, as the incision is made inside the mouth.
With chin implants, a small scar may be present if an external incision beneath the chin is used.
Is the procedure carried out under general anaesthetic?
Sliding genioplasty is usually performed under general anaesthetic.
Box genioplasty and chin implants may be carried out under local anaesthetic in suitable cases.
Will I need to stay in hospital?
Generally, no.
Most patients are able to return home on the same day following treatment.
Can the chin be moved forward or reduced at the same time?
Yes.
Depending on the patient’s requirements and facial proportions, the chin can be repositioned to increase or decrease projection as part of the same procedure.
How long does the procedure usually take?
The procedure takes approximately one hour.
The exact duration may vary depending on the technique being used and whether it is being combined with another procedure.
What is the typical recovery period?
Initial healing usually takes around one week.
Bone union (where the repositioned bone heals firmly back together) typically takes around six weeks. Where implants are used, capsule formation (the body’s natural healing response around the implant) generally takes around one month.
How painful is surgery and recovery?
Severe pain is unusual following genioplasty.
Some discomfort is expected during the early stages of recovery. Antibiotics and, in some cases, steroids may be prescribed to help reduce swelling, while simple pain relief is usually sufficient after the first 24 hours.
How much swelling is normal after genioplasty?
Swelling is a normal part of recovery and will vary depending on the type of procedure performed.
Box genioplasty generally produces less swelling than sliding genioplasty, although some swelling should be expected with both techniques.
Can numbness happen after surgery?
Yes.
There is a risk of numbness because the nerve supplying sensation to the lower lip may be affected during surgery.
How long does numbness usually last?
If the nerve is bruised, sensation may take up to six months to recover.
In cases where the nerve is damaged, numbness may be permanent.
When can I return to work and normal activities?
Most patients are able to return to work and routine daily activities after approximately ten days.
Recovery times can vary depending on the individual and the procedure performed.
When can I exercise again?
Light cardiovascular exercise can usually resume after one week.
Contact sports should generally be avoided for six weeks to allow healing to take place.
Still deciding whether genioplasty is right for you?
