Lipoinjection or fat transfer treatment involves the process of transferring excess fat (liposuction) from the abdomen or the buttocks (chin, waist or hips) to other areas where fat has been lost. The lipoinjection method has the advantage of using autologous fat in the treatment of different conditions. Therefore, problems associated with rejection or allergies are diminished. Although some of the fat may be absorbed by the body, results are usually long-lasting.
What are some common uses of this procedure?
Lipoinjection treatment is commonly used as a part of a major procedure such as facial rejuvenation (facelift or rhytidectomy) to fill some deep wrinkles, the nasogenian folds (laugh lines), or the horizontal forehead lines. Lipoinjection alone is a good option for facial rejuvenation and is frequently used in buttocks augmentation. Lipoinjection is also used for patients with soft-tissue insufficiencies in reconstructive surgery.
Although lipoinjection is a quite simple procedure, it requires substantial clinical experience to be performed. In some cases, more than one session may be needed to achieve the desired outcome.
Preoperatively the surgeon marks the areas of liposuction and fat injection.
This is a very important step, as patient positioning on the operating table may modify the form of some depressions and prominences of the body.
The procedure techniques may vary according to the individual conditions of the patient. Most of the procedures are performed with the patient in the supine position (lying down with face up) or with patient in the prone position (lying with face down). The circulating nurse will ensure that all body pressure points as well as breasts and nipples are padded. You will be covered with a warm blanket to keep you warm during surgery. Also, the intravenous therapy is initiated to give you liquid substances and medications directly into a vein.
The liposuction technique involves the use of a small tube called a cannula, which is inserted through tiny incisions under the skin to remove fat. The latest technique of liposuction employs ultrasound energy to liquify fat cells, which are removed by the cannula. Because of its better quality, most surgeons prefer fat from conventional liposuction to be used for lipoinjection.
Fat obtained for lipoinjection is decanted to separate fat from tumescent fluid and other fluids. To maintain normal body fluid balance, the surgeon maintains during the procedure the administration of intravenous fluids. Drainage tubes are placed to diminish the risk of seroma. Incisions are closed with sutures, an antibiotic dressing is placed over the incision and a surgical tape is applied.
After the procedure a compression bandage is applied. There are a wide variety of bandages with many different applications. Your surgeon will recommend the most appropriate compression garment for you.
After the extraction and processing of the autologous fat, local anesthesia is used to treat the recipient sites. Then the fat is injected in the desired areas. The treatment sites should be filled more than necessary as some fat will be reabsorbed on the following weeks.
What kind of anesthesia is used during the lipoinjection procedure?
When lipoinjection is part of a major procedure such as the liposuction, the surgeon makes use of the same anesthesia the patient is receiving. In other cases, the procedure may be performed under local anesthesia only, or with intravenous sedation.
How long does this procedure take?, Will I require hospitalization?
Lipoinjection procedure may take 1 hour and it is done on an outpatient basis. If lipoinjection is performed in combination with other surgical procedure may take a little more.
1 You may experience a mild discomfort, which may be minimized with pain medication.
2 You should expect some bruising and swelling as a natural part of reconstruction surgery. This condition will fade within the following 48 hours.
3 Avoid sun exposure until your complete recovery.
4 Most people resume normal activities after 8 days.
