How can seromas be prevented?

Seromas are prevented by 1) avoiding excessive surgical trauma to the delicate lymphatic vessels within fat, and 2) by encouraging post-operative drainage of lymph fluid (serum) from the fatty tissues treated by liposuction. First, the use of microcannulas can reduce the risk of seromas. Micro-cannulas are relatively small liposuction cannulas having an outside diameter less than 3 millimeters. By making relatively small tunnels within the targeted fat, micro-cannulas do not create large empty cavities within which a seroma can form as readily as larger cannulas. Large cannulas remove fat more rapidly, but are more likely to cause seromas because large cannulas tend to damage lymphatic vessels, and create larger cavities within the fat. Second, when incisions are closed with stitches, a relatively large amount of fluid is trapped under the skin where it collects and stagnates in the tunnels within the fat, thus causing a seroma. By not closing incisions with stitches (the “open-drainag
