Liposuction is the technique by which localized deposits of fat are removed using thin cannulas (tubes) through tiny incisions. Liposuction is also known as suction lipectomy, liposculpture, and SAL (suction assisted lipectomy). Liposuction has been performed for many years, but the most significant advances in liposuction techniques have occurred over the past two decades.
The level of safety and efficiency in liposuction has been dramatically increased by the "pre-wetting" of the fatty tissues with a solution that delivers local anesthesia as well as epinephrine, or adrenaline, to constrict the vessels within the tissues and substantially minimize bleeding during liposuction surgery.
What types of liposuction are available?
The main liposuction techniques are tumescent liposuction and superwet liposuction, both of which utilize the infusion of wetting solutions to provide anesthesia and vasoconstriction (shrinking of the blood vessels).
The additional liposuction modalities include SAL (suction assisted liposuction), PAL (power assisted liposuction), UAL (ultrasound assisted liposuction), VAL (vaser assisted liposuction), SmartLipoTM (laser assisted liposuction), SlimLipoTM (laser assisted liposuction), and others. The benefits of these liposuction modalities are emulsify fat during or prior to liposuction. The laser liposuction modalities are purported to promote tissue tightening, although the effects have not yet been definitively proven.
What types of anesthesia are used for liposuction?
Liposuction can be performed with local anesthesia (tumescent liposuction or superwet liposuction) only, with IV sedation or twilight anesthesia, or under general anesthesia. The extent of liposuction and the areas that require treatment will determine the type of anesthesia.
Thanks to sharing useful information. Most fat women want to get rid of the fat. The liposuction in Singapore is their first choice. Hope all of them will be fit. Good luck!
