Liposuction Cannulation Size
The Impact of Liposuction Cannulation Size is an important consideration in the selection of a surgeon. A smaller cannula will be less effective at removing fat than a larger one. Moreover, a microcannula will leave fewer scars, thereby decreasing the number of follow-up visits. The largest difference between microcannulas and larger cannulas is the total aperture area. The bigger the aperture, the less fat will be aspirated per stroke. A large round aperture is best suited for low-viscosity adipose tissue, while a tiny round one is better for higher-viscosity adiposis tissue.
A large-diameter cannula can remove the same volume of fat from the outer thigh. Larger cannulas result in a smaller wound surface area, which means fewer transected capillaries. However, this approach is not ideal for patients with large legs, and large cannulas should be reserved for small thighs. In addition, larger cannulas can reduce the amount of bleeding that is associated with liposuction.
Although a larger cannula is generally less painful, it may not be the right choice for some patients. It may lead to uneven contours, poor skin elasticity, or a delayed healing. It can also lead to an unusual amount of bleeding. Besides the risks of complications and scarring, a large cannula also has the risk of puncturing the skin and requiring emergency surgical repair.
The size of the cannula is important in liposuction. The smaller the cannula is, the more fat grafts will be retained. The corresponding amount of fat cell damage will be lower. Furthermore, smaller fat particles are more likely to retain their integrated structure. This study showed that a smaller cannula would be more effective in a small patient.
The Impact of Liposuction Cannulation Size
The size of the cannula is important for two reasons. First, it facilitates fat extraction. But it also creates lumpiness, more pain, and more bruising. Second, a larger cannula can lead to a more uneven contour. It is better to use a smaller one in the case of a smaller patient. The larger cannula will allow for more precise placement and less bruising.
For optimum results from tumescent liposuction, surgeons prefer to use microcannulas. They reduce the risk of dermal complications and increase the chances of avoiding complications. In fact, smaller cannulas are more likely to result in less swelling and bruising. In general, however, larger cannulas can be more effective in removing fat in small areas.
In the present study, fat was harvested from five patients undergoing elective liposuction with a standard set of cannulas and microcannulas. The investigational cannulas were manufactured with known internal diameters and a single opening. Once the fat was extracted, the particles were examined under a magnification microscope in the operating room. The first operation included the injection of progressively smaller cannulas until an obstruction was observed.
