DEFINITION, AIMS AND PRINCIPLES

Liposuction can radically and definitively diminish localized areas of protruding fat.
These localized areas of protruding fat do not go away with strict diet and exercise.
Conversely, liposuction is not a method for losing or controlling weight. Thus, a properly performed
liposuction will not replace an improvement in lifestyle. Liposuction is not a treatment for obesity.

 

The principle of liposuction (as presented in 1977 by Yves-Gérard ILLOUZ)

is to remove fat through very small skin incisions, with atraumatic and blunt-tipped cannulas.
These cannulas are attached to a closed negative pressure system, which permits safe and sterile aspiration of excessive fat cells.
Practically, liposuction can be applied to numerous body areas: hips, outer thighs, abdomen, knees, calves, ankles and upper arms.
Technical improvements have permitted to extend its action to the face and neck (ie, double chin and "face oval").
Recent progress in the field of superficial liposuction,
performed with very thin cannulas have reduced skin trauma or bruising. It has even improved the final result by enhancing skin shrinkage, when performed with great attention and skill.
Meanwhile, it must be kept in mind that liposuction, however common a procedure it has become, remains a genuine surgical intervention, that ought to be performed by a skilled and qualified Plastic Surgeon, specially trained for this technique, in a truly surgical environment.

 

BEFORE THE PROCEDURE

A preoperative check-up is made following your surgeon’s recommendations.

 

HOSPITAL STAY AND TYPE OF ANESTHESIA

Type of anesthesia

Liposuction can be performed, depending on the amount of areas to be treated, either under local anaesthesia, local anaesthesia associated with intravenous sedation or general anaesthesia. In some cases, regional anaesthetics, such as an epidural.
The type of anaesthesia will be chosen after a discussion between yourself, your surgeon and your anaesthesiologist.

Hospital stay

The duration of hospitalisation depends on the amount of fat removed. It can be short (a few hours) for small liposuctions under local anaesthesia, or longer (1 or 2 days) for larger liposuctions under general anaesthesia.

THE PROCEDURE

Skin incisions are small (3 to 4 millimeters) and discrete, usually hidden in a natural fold. Fat cells from deep and superficial fat layers are aspirated through smooth cannulas tunneled though ubcutaneous tissue layers, taking care to avoid nerves and blood vessels.
The amount of fat removed is adapted to the amount of the overlying skin, which represents a fundamental factor for the quality of the final result.
Post-operatively, a pressure dressing is made with an elastic bandage. Very often a special pressure garment is put on top of it.
The duration of the procedure depends on the amount of fat removed and on the number of body areas to treat. It can vary from 20 minutes to 3 hours (average time is 1 to 2 hours).

 

AFTER THE OPERATION

The necessary time needed to recover from surgery is proportional to the amount of excess fat removed.
After surgery, you will observe swelling and bruising in the treated areas.
Pain can vary from one patient to another, but it is usually mild, due to the use of very thin cannulas.
Fatigue is common in the first few post-operative days, especially after large liposuctions.
You can go back to your usual activity 4 to 7 days after surgery, again depending on the extent of your liposuction and your type of professional activity.
Bruising usually disappears 10 to 20 days after surgery.
It is strongly recommended to wear a pressure garment for 2 to 4 weeks.
It is possible to start sports again at least 3 weeks after surgery.
There is no dramatic improvement of body contour in the first 2 to 3 weeks, because of the tissue swelling (edema) in the operated areas.
It is only after 3 weeks and with the resorption of this edema, that results will begin to appear. The skin will retract completely in 3 to 6 months over the new contours and readapt to the new silhouette.

THE RESULT

The final result can be best appreciated 6 months after the procedure. It is most satisfactory when the patient selection and technique are properly done, permitting removal of localized fat deposits and producing skin retraction.

DISAPPOINTING RESULT

It has already been explained how liposuction, when correctly indicated and performed, can offer a real improvement to patients in terms of satisfying results and conformity to their expectations.
In some cases, localized imperfections can be observed, which must be distinguished from genuine complications: insufficient corrections, residual asymmetry, surface irregularities. These can be corrected secondarily under local anaesthesia after 6 months.


POSSIBLE COMPLICATIONS

  • Thrombo-embolic accidents (blood clot in the veins of the legs, pulmonary embolism) are rare, but can be lifethreatening.
    They can be prevented by strict prophylactic measures, such as standing and walking as soon as possible after surgery, wearing compression stockings, or heparin therapy (low doses of heparin injected under the skin)
  • Blood clots (haematomas) are quiet rare but can occur. They can be evacuated to prevent an impairment of the final aesthetic result.
  • Infection, though common, can be treated with drainage and antibiotics.
  • It is common to notice 8 days after surgery a lymph collection accumulating under the skin. Such a collection can be drained and will dry up rapidly without sequela.
  • Localised skin necrosis. Large areas of necrosis is rare. They can be prevented by a proper surgical examination and a cautious and well-executed operation, with moderate tension on sutures.
  • Numbness of abdominal skin may be observed, frequently in the lower abdomen. It is usually transient and most patients recover normal skin sensation after 3 to 12 months.
  • In some patients with very damaged skin or skin with poor circulation, the healing process may be delayed resulting in conspicuous scars, which may necessitate a second operation.
