The most common problem after liposuction is surface irregularity or waviness. This is less common as the surgeon becomes more experienced, but may occur even with an experienced surgeon in 5-10% of cases.
It is less common when multiple small incisions are used along with small cannulae. Cross suctioning also reduces the risk as do feathering the edges of the area and suctioning both superficially and deeply.
If contour irregularities develop no attempt is usually made to correct them for at least six to twelve months. Massage alone helps many patients.
If surgical correction is needed the surgeon can suction raised areas around the depression, and fill in the depressions with fat grafts. If the skin is loose then it can be surgically removed by excision. Cellulite is not usually improved by traditional liposuction and the appearance may even be made worse. Ultrasonic liposuction may help cellulite and cause less irregularity.
