Is there any real advantage in the double-lumen cannula?



Is there any real advantage in the double-lumen cannula?



Aesthetic Plastic Surgery 21(1): 38-42



The author demonstrates one of liposuction's great problems, what he calls the "contra-vacuum," which forms inside the cannula while it is inserted under the skin. To keep liposuction effective, an ascending pressure is needed while the holes of the cannula are deep inside the tissues. The results are higher pressure, more tissue trauma, less effectiveness. To prevent these problems, the author developed a double-lumen cannula in 1983; because of a secondary tube outside it, there is no contra-vacuum formation. He presents here his experience in large liposuctions with a new cannula model, thinner than the first one, but also very effective.
