A facial liposuction procedure normally takes about 45 minutes to an hour to perform.
Facial liposuction does not differ much from liposuction elsewhere on the body, except in scale. A smaller area is being treated and a smaller amount of fat (usually only a few ounces) is being removed.
Facial liposuction is usually done under light sedation with local anesthesia, unless you are having other facial procedures or other cosmetic surgery done at the same time.
Your surgeon will make an incision about 2 to 4 cm long either in the angle of your lower jaw, just under your chin, or between your gums and the bottom of your inner lower lip.
With the external incisions (at the jaw angle or under the chin), the cannula will be inserted into the incision and the tip will be moved back and forth to loosen the fat. The suction will remove the loosened fat cells.
With the intraoral incision (in the mouth), care must be taken as to not press the cannula directly against the under part of the skin. This can remove too much superficial fat and create dents or lumps, or mottle the skin. Some surgeons prefer the external incisions although with proper skill the intraoral technique can produce a wonderful result.
Either way manual fat removal is also an option, as with buccal fat extraction, and for many surgeons a preference.
The incisions are then closed. You may have an antibiotic-soaked piece of gauze placed between your lower lip and your gums and a pressure dressing is wrapped around the top of your head to underneath your chin.
Take it easy and sleep on two pillows to keep your head elevated for the first 1 to 2 weeks, or however long your surgeon says. Your neck and lower face will look even more swollen a few days after surgery then they did on the first day. But the swelling will dissipate, as will any bruising.
If you have intraoral incisions, your diet may be restricted. Wash all fruits and vegetables and avoid raw fish (sushi) and very rare meat or other foods that could contain high amounts of bacteria. These foods could increase your risk of infection. You will probably be told to rinse with an antiseptic solution several times a day. Don’t play with the incisions with your tongue or pick at them.
Your swelling will subside within a few weeks and your chin will become more defined. You may experience odd sensations of hollowness under your chin, tingling, sporadic sharp pains, or pulling, burning, and cold sensations. These are normal and usually subside within the first few weeks.
There is the risk that your chin and cheeks may be numb; usually, this is temporary and subsides within the first few weeks. However, it could become a permanent issue. Puckering of the skin under the chin may also occur. Excess scar tissue and lumps are possible as well.
