Liposuction is the process of removing the fat. Tumescence helps make the procedure safer. Yes, it can be done under local anesthesia--the tumescence. I would suggest meeting with a surgeon who does awake liposuction and discuss all your concerns and options.
Tumescent describes the fluid that is used to reduced the bruising, reduce the pain and decrease the amount of blood loss. Smart describes the tool used to perform the liposuction, which is unnecessary.
I find that VASER is the best for body shaping and tightening. I suggest seeing an expert. All forms of liposuction are tumescent. I find that ultrasound gives the most in shaping and tightening. Best, Dr. Emer.
Glad to hear that you have done your research and found a Board Certified Plastic Surgeon! With liposuction, the truth is that all of the technologies work: vaser, ultrasonic liposuction, laser liposuction, etc... There is an ongoing debate which device may help with skin retraction and fine contouring, but they all are effective removing fat. Most surgeons have their preferences and devices that they feel comfortable with and feel produce consistent, predictable results. You ask which gets rid of more fat, but the truth is that is more dependent on the judgment of the surgeon than the technology being applied. Small areas of liposuction can be performed under local anesthesia, often with either oral or IV sedation. Full body, transformative liposuction often requires general anesthesia. Good luck as you consider your options.
Liposuction under tumescent local with a little iv sedation is optimal. This way your doc can stand you up occasionally during the procedure to fine tune the results.
