Why don't some doctors use drains after lipo and BBL procedures?

Drains are not typically required for liposuction or Brazilian Buttlift procedures.  The critical structures called lymphatics are not cut with liposuction.  Instead, the fat is suctioned leaving behind the lymphatics intact.  Drains can help with more aggressive liposuction with ultrasound, large volume liposuction or surgery (such as a tummy tuck) combined with liposuction. The drain(s) wick out the tumescent fluid that makes liposuction safe and the swelling fluid into a bulb to minimize the fluid collecting under the skin.  Short answer- drains are not usually required for procedures such as liposuction.  Best Wishes!!   

There is no indication for drains in liposuction. As matter of fact, I'm not even sure how you could get them in after properly perform liposuction.

There is no need for them.  There is no evidence they help and they can increase risk of infection as well.  Best, Dr. Emer.

There areno drains in the procedures I do because of the suturing technique I use.Drains are not necessary because there shouldn’t be room for fluid to collect.

There is no evidence that drains offer any advantage in liposuction or Brazilian Butt Lifts so there is no need to use them.

Drains are a time honored technique designed to hopefully minimize hematoma or seroma formation and decrease swelling.However, for many procedures they have not been well studied scientifically to be able to tell honestly whether they actually help or not.Some studies have been done with various plastic surgery procedures e.g. facelift,breast reduction and others where they don't seem to make much of a difference.Many surgeons use drains routinely for certain operations and others don't so there can be an honest difference of opinion on their utility from one doctor to the next,and there can sometimes be no right or wrong answer to your good question.
