[Application of liposuction and its clinical significance]

300 liposuction patients involving 444 anatomical areas are reported in this paper. The clinical significance of the applied anatomy and the comparison between groups are analyzed. 1. The distribution of the liposuction areas. 2. The distribution of blood vessels in the abdominal wall, buttocks and thighs and its relation to the volume of fat removed as well as blood loss. The blood vessels are so abundant in the abdominal wall that the blood loss is larger than that in the buttocks and thighs in the operation. According to the anatomical characteristics of distribution of the blood vessels, the authors pointed out a few "relatively forbidden areas". In group 2 we intentionally avoided doing liposuction in these areas. The results showed that the blood loss was less than that in group 1 and that the volume of fat removed could obviously be increased. 3. The characteristics of liposuction in severe obesity or in patients over 90kg body weight: The aspirate volume is big; the blood versus fat ratio is low. So it is possible to increase the aspirate volume. The elasticity of skin of the abdominal wall is very high. It is not necessary to remove skin in very obese patients with abdominal dermatochalasis.
