A The downside of infusing the Tumescent Anesthetic under your skin prior to the Vaser treatment is that there is a large volume of fluid intermixed with the fat cells which makes it difficult for any surgeon to be certain that (s)he has removed the maximum amount of fat from one segment of the body. Also, many surgeons will quantitate the volume of fat removed from one thigh then try to remove an equivalent volume from the other thigh to maintain equilibrium of the natural curves of the female form. Given the fact that it is a localized issue you have several options to "fix" the lack of harmony; Emsculpt, Vanquish, and other non - invasive treatments vs. a revision lipo of the left thigh.
