Procedure:
Improve body shape by removing exercise-resistant fat deposits with a tube and vacuum device. Can be performed using the tumescent technique, in which targeted fat cells are infused with saline containing solution with a local anesthetic before liposuction to reduce post-operative bruising and swelling. Common locations for liposuction include chin, cheeks, neck, upper arms, above breasts, abdomen, buttocks, hips, thighs, knees, calves, ankles.

For larger volumes of fat or for fibrous body areas, ultrasound-assisted lipoplasty (UAL) may be used. UAL is a new technique in which a ultrasound probe is inserted beneath the skin to "liquify" the fat before it is suctioned.

Length:
1 to 2 hours or more. UAL: 20-40 percent longer than traditional liposuction.

Anesthesia:
Local, epidural, or general.

In/Outpatient:
Usually outpatient. Extensive procedures may require short inpatient stay.

Side Effects:
Temporary bruising, swelling, numbness, soreness, burning sensation. Tumescent: Temporary fluid drainage from incision sites. UAL: Larger incisions for cannula.

Risks:
Asymmetry. Rippling or bagginess of skin. Pigmentation changes. Skin injury. Fluid retention. Excessive fluid loss leading to shock. Infection. UAL: thermal burn injury caused by the heat from the ultrasound device.

Recovery:
Back to work: 1 to 2 weeks. More strenuous activity: 2 to 4 weeks. Full recovery from swelling and bruising: 1 to 6 months or more. Use of tumescent technique or UAL may decrease post-operative bruising and swelling.

Duration of Results:
Permanent, with sensible diet and exercise.
