Drains are not necessary for liposuction. If liposuction of the abdomen is combined with a tummy tuck, the short-term use of drains may be necessary in selected cases. In liposuction to correct a man’s breast in conjunction with the removal of a mammary gland, a drain is sometimes also used. Thanks to the use of a tumescent solution (injection of water with adrenaline) before liposuction, the use of blunt cannulas, careful preparation for the operation, good aftercare and a certain amount of sensitivity, there is no need to worry about post-operative bleeding. Patchy bleeding of the skin is unavoidable. The bruises will disappear on their own after five to ten days.
