In recent years, several technologies have emerged to enhance the outcomes of liposuction or liposculpture and to simplify the procedure. Among them are VASER technology, which utilizes ultrasonic sound waves and was widely used a few years ago, as well as power-assisted liposuction (PAL), where a motor facilitates the movement of the liposuction cannula used to extract fat.
Laser-assisted liposuction is an excellent tool for various scenarios, particularly for treating fibrosis or scar tissue that forms under the skin after a previous liposuction procedure. By breaking down fibrotic tissue, the laser aids in fat extraction and improves the procedure’s efficiency.
There are two main types of lasers:
High-Power Laser:
Operating at a power range of 10 to 25 watts, this laser is strong enough to cut through small pieces of wood, such as tongue depressors. It is commonly used for biopolymer removal due to its precision and power.
Low-Power Laser (Cold Laser):
Known colloquially as the “cold laser,” this operates within a range of 10 to 20 milliwatts. While less powerful, it is highly effective, particularly for breaking down fibrosis during second or third liposuction procedures.
Both types reduce the risk of bleeding during and after surgery, while also promoting skin retraction. Although I have used both, I personally prefer the low-power laser due to its safety profile. The only side effect reported by patients is a mild burning sensation on the skin that lasts one or two days and improves significantly with routine postoperative medication.
The Role of Laser in Liposuction
It is important to note that the laser itself does not extract fat. After using the laser, traditional fat extraction with a liposuction cannula is still required. While using the laser adds time to the surgery, it greatly facilitates fat extraction, shortens the overall procedure time, and improves its safety.
Both laser devices require a generator to produce the laser beam, which is transmitted through an optical fiber. The devices differ in light frequency and intensity, measured in power levels. With the high-power laser, it is necessary to track the total energy delivered to the skin, whereas with the low-power laser, the focus is on the duration of use.
Applications and Results
Laser-assisted liposuction delivers particularly satisfying results in neck and chin liposuction, producing high levels of patient satisfaction.
In cases of secondary or tertiary liposuction, lasers help achieve harmonious results by improving skin retraction and correcting irregularities caused by improper use of liposuction cannulas in previous surgeries.
Consulting Your Surgeon
If you are considering laser-assisted liposuction or liposculpture, ask your surgeon about their experience with high- or low-power lasers to enhance the procedure’s results. The use of laser technology, combined with expert surgical technique, can significantly improve outcomes and patient satisfaction.
