Liposuction


Q: What is liposuction and body sculpting?

A: Liposuction is a surgical technique that improves the body’s contour by removing excess fat from fatty deposits location between the skin and muscle. Body sculpturing by liposuction is literally a dream come true.

Liposuction involves the use of a small stainless steel tube called a cannula. Connected at one end to a specialized suction pump, the cannula is inserted through tiny skin incisions. The removal of fat is accomplished as the suction cannula creates tiny tunnels through the fatty layers. After surgery, these tiny tunnels collapse, resulting in an improved body contour.

Q: About Fat

A: The body fat of an adult tends to increase gradually over the years. After the age of 30, an individual tends to add fat according to a genetically predetermined pattern. This fat distribution is often resistant to exercise and dieting. An example of genetically predetermined fat distribution that is resistant to dieting and exercise is the fat that appears on the abdomen and hips of a woman after pregnancy. For many people who have inherited the tendency to accumulate excessive fat, liposuction is the only realistic means of significantly changing the body’s silhouette.

Q: What areas can be treated by liposuction?

A: The most frequently treated areas in women are the abdomen, hips, thighs, knees, calves, ankles, and beneath the chin. In men, who comprise about 25% to 30% of patients who undergo liposuction, the most commonly treated areas include the love handles, abdomen, breasts, and the neck and chin area.

Q: Are the results of liposuction permanent?

A: Fat cells that are removed by liposuction do not grow back. As long as the patient does not gain an excessive amount of weight, the new, more pleasing silhouette is permanent.

A woman who always tends to put weight on her thighs and knees, will find that after liposuction, these areas are less likely than other areas to accumulate fat when she gains weight. In fact, a number of patients have had liposuction and subsequently gained weight. In these patients, the areas originally treated by liposuction generally maintain their new desirable silhouette, whereas areas not treated by liposuction are the sites of new deposits of fat.

Q: What is the Tumescent technique?

A: The Tumescent Technique of liposuction was developed in 1985. The Tumescent technique involves the use of large volumes of a dilute solution of lidocaine (a local anesthetic) in combination with the vasoconstrictive drug, epinephrine, which shrinks capillaries.

Local anesthesia used in the Tumescent technique for liposuction is so effective that patients no longer need intravenous sedatives, narcotic analgesics, nor general anesthesia. This technique is now considered the safest form of liposuction for removing very large amounts of fat because there is virtually no blood loss. Not only has the Tumescent technique proven to be safer than the standard technique using general anesthesia, but it also has proven to be less painful, has minimal post operative recovery time, and produces optimal cosmetic results.

With the Tumescent technique, infiltrating the local anesthesia is associated with minimal discomfort. Once the area has been completely numbed, surgery in that area is essentially painless. In addition, because the numbness remains in the treated area for more than 12 hours, there is no pain immediately after surgery.

Q: What are the risks?

A: As with any surgical procedure, liposuction is associated with certain common side effects such as bruising, swelling, and temporary numbness. Although irregularities of the skin are possible following liposuction, this side effect is minimized by the Tumescent technique. When larger cannulas are used, occasionally there are patients with an irregularity of the skin. Since smaller, microcannulas became available, noticeable irregularities are very rare. Because of the slow resolution of post liposuction swelling, the ultimate results following liposuction usually require 12 to 16 weeks to become fully apparent. Nevertheless, patients can usually see dramatic improvements within two to four weeks after surgery.

Although the results of liposuction are often quite spectacular, it is not realistic to expect perfection. Liposuction of the thighs, while improving the silhouette, does not necessarily eliminate the subtle “puckering” of the skin that is often referred to as “cellulite.” Liposuction with the Tumescent technique does reduce the degree of cellulite but it is unlikely to eliminate it. Rare problems that can potentially occur with any surgical procedure include infections, bleeding and nerve injury, The Tumescent technique, however, minimizes these risks.

Q: How does the Tumescent technique reduce risk of infection?

A: Infections are extremely rare, regardless of whether or not the anesthetic technique is that of general anesthesia or local anesthesia. Although there have been reports in the medical literature of patients who have had serious infections following liposuction surgery, to the best of our knowledge, there have never been any patients who have had an infection following Tumescent liposuction performed using only local anesthesia. Lidocaine, the local anesthetic that is used for the tumescent technique, kills bacteria. With the Tumescent technique the areas that are being treated surgically are those same areas that will receive the local anesthetic that kills bacteria.

Q: When can I return to normal activities?

A: Because of the significant decrease in swelling and decrease in inflammation and pain after surgery, patients are able to return to normal physical activities very soon after the procedure. There is no limitation of physical activity other than what common sense would dictate. Some patients are able to return to jogging, golf, or light aerobic exercise within a day or two after surgery. Some patients do find the soreness after surgery to be more significant than others, but on the average, most patients are surprised at how quickly they are able to return to normal activity.

Q: How does the Tumescent technique result in better and smoother results?

A: Because very small cannulas are used with the Tumescent technique, it permits a more delicate and gentle approach to liposuction as the surgeon can control the direction and position of the cannula with much more accuracy. This results in a greatly reduced risk of inadvertently approaching the undersurface of the skin too closely and unintentionally causing skin irregularities. Further, the use of very small cannulas enables the surgeon to make such small incisions that no stitches are used. The wounds heal by themselves and virtually disappear over time.

By not using stitches to close skin incisions, the rate of healing is faster. Another benefit of not stitching the incisions closed is that, after the procedure, the open incisions permit easy drainage of the slightly blood-tinged anesthetic solution. This has a dramatic effect in minimizing bruising. Most patients notice that bruising is almost entirely absent after surgery.

Q: How many types of liposuction exist?

A: Suction-assisted Liposuction (SAL): It is the traditional and time-honored method of liposuction. Using general anesthesia, regional anesthesia, heavy sedation or totally under local tumescent anesthesia, the cosmetic surgeon removes the fat by inserting a small, hollow tube (cannula) connected to a vacuum aspirator device, directing the cannula into the areas to be suctioned through tiny incisions. Power-Assisted Liposuction (PAL): A cannula with a back and forth, or rotational, motion of the tip passes through the tissue to suction out fat and fibrous or scarred tissue. The benefits are (1) minimal trauma to the tissues and (2) reduced effort for the surgeon.
Ultrasound-assisted Liposuction (UAL). Vaser Liposuction: Intermittent or continuous bursts of ultrasonic energy (sound waves) are transmitted to the tip of the cannula to break up and liquefy fat cells which are then removed by suction. External ultrasound-assisted liposuction (E-UAL) uses external ultrasound waves to alter the fat cells in an effort to liquefy the fat before it is suctioned. Laser-assisted Liposuction (LAL): At the present time there are two laser-assisted liposuction technologies available in the USA:

     A. Low-level Assisted Liposuction (4L Erchonia): the device is a portable low-level laser unit (dual-diode laser) that creates a thin beam of red light. Its external application on the skin helps to create fat liquefaction, making the suction of the fat easier and quicker. Moreover, the use of hte laser after liposuction eases pain, reduces bruising, improves healing, and provides a more rapid recovery. This is a non-invasive laser that does not create pain during its use and it is nearly imperceptible to the patient.

     B. SmartLipo Laser. Laserlipolysis (pulsed, Nd YAG laser): This laser has recently received FDA approval. A small cannula containing a laser fiber is inserted into the skin, the cannula is moved back and forth delivering the laser’s energy to the fat cells causing them to rupture and easily drain away. The laser energy also interacts with the dermis resulting in collagen shrinkage responsible for a good contraction of the skin. SmartLipo is minimally invasive procedure that can be done easily with local tumescent anesthesia. The SmartLipo is a great adjunct to standard liposuction (suction-assisted, power-assisted, laser-assisted liposuction), though it can not replace conventional liposuction. They have found the SmartLipo ideal for treating small areas of the face, neck, arms, breasts, high definition liposculpturing such as abdominal etching (“6-pack etching”), and areas of loose and flabby skin (floppy skin.)

Q: What type of liposuction is the best?

A: All the liposuction techniques offer advantages and disadvantage; therefore, the use of specific liposuction equipment used alone or in combination with other liposuction devices, must be individualized based upon the patient needs, desires, technical feasibility and realistic expectations. At the Pelosi Medical Center all of the liposuction techniques are available. Dr. Aly use all the techniques of liposuction, tailoring them to the particular part of the body or patient. Be aware that many claims made by manufactures or physicians using a specific liposuction equipment system have been never been confirmed by rigorous clinical studies. They are only marketing strategies to lure potential customers. They use statements such as…”If your doctor doesn’t use our type of liposuction, you should look for a physician that uses it, because out system of liposuction is not really liposuction but something better.” In general, the use of ultra-sound assisted liposuction including the Vaser® Liposelection require larger skin incisions and the need to suture them at the end of the surgery. They are also associated with more complications than the standard suction-assisted, power-assisted, and laser-assisted liposuction performed under local anesthesia. Such complications include burning and/or tingling, swelling, skin burns, and fluid collecting under the skin (seromas).
