Liposuction has come a long way since its development in the 1980s, especially with the introduction of laser liposuction. This article highlights how this newer technique offers several advantages over traditional liposuction.
Laser liposuction involves three key steps:
1. **Local Anesthesia:** A local anesthetic is injected into the fat to numb the area.
2. **Laser Application:** A laser is used to melt the fat and heat the skin. This heat stimulates collagen production, which improves skin quality and tightness.
3. **Fat Removal:** Similar to traditional liposuction, the liquefied fat is then sucked out using a cannula. This step focuses on sculpting the body.
### Advantages of Laser Liposuction:
**1. Improved Skin Retraction:**
The heat from the laser stimulates cells to produce collagen for weeks after the procedure. This results in better skin tightening and quality, which is crucial for a good cosmetic outcome.
**2. Local Anesthesia:**
Unlike traditional liposuction, which requires general anesthesia and carries risks of complications, laser liposuction uses local anesthesia. Dr. Jeffrey Klein has shown that removing two to three liters of fat with local anesthesia is both safe and effective, eliminating the risks associated with general anesthesia.
**3. Smaller Cannulas:**
Traditional liposuction uses larger cannulas (4-6mm), which can increase the risk of uneven fat removal. Laser liposuction uses a smaller cannula (1.2mm for the laser and 2-3mm for suction), leading to more precise fat removal and fewer irregularities, though the procedure does take longer.
**4. Reduced Blood Loss:**
Local anesthesia includes adrenaline, which minimizes blood loss by constricting blood vessels. The laser also helps to coagulate small blood vessels, reducing bruising and speeding up recovery.
**5. Better Aesthetic Control:**
Patients remain awake during laser liposuction, allowing the surgeon to ask them to change positions for better visual inspection. This ensures a more accurate and aesthetically pleasing result.
**6. Faster Recovery Time:**
Staying awake means the surgeon can take their time and be less aggressive, causing less tissue trauma. This leads to less swelling, bruising, and pain, with many patients resuming normal activities within two days without needing painkillers.
### Summarizing the Benefits:
Laser liposuction offers a gentler approach with a quicker recovery, significantly fewer risks, and superior cosmetic results compared to traditional methods. The downside is the longer duration of the procedure, typically three hours versus one hour for traditional liposuction. This is why big hospitals might not offer it, as it’s less profitable for them.
To find a good practitioner, look for private clinics that specialize in laser liposuction. The initial consultation is critical; your doctor should explain the procedure thoroughly and address all your questions.
