Sharp instruments used to cut rather than avulse in liposuction surgery have been advocated intermittently since the advent of liposuction.1 Fischer's2 planatome was discarded when it was found that crisscross tunnels resulted in a smooth skin surface that was the supposed benefit of the planatome (G. Fischer, MD, written communication, April 5, 1997). The curette method by Kesselring and Meyer3 was noted to be only beneficial for the greater trochanteric regions.4 Attempts by Goodstein and Hoefflin5 to use a cannula with a sharp trailing edge acting as a curette in the subdermal tissues resulted in lymphorrhea (severe edema and fluid) as well as occasional skin necrosis.
The liposhaver by Becker et al1 is yet another attempt to use a sharp instrument that can injure vessels and nerves in a surgery that is relatively safe with blunt cannulas. Ultrasonics has a much sounder basis but
