title: [A comparative study on external ultrasonic, internal ultrasonic and simple negative pressure liposuction operations under tumescent anesthesia].
abstract: OBJECTIVE
  To compare the effects of the external ultrasonic, the internal ultrasonic and simple negative pressure liposuction operations under tumescent anesthesia.
  
  
  METHODS
  The fat volume, operative time, complications and other indexes of liposuction in 276 cases were collected and compared.
  
  
  RESULTS
  External ultrasonic liposuction rapidly emulsified the fat with the least complication. The effects of the internal ultrasonic liposuction was next to the external ultrasonic method while the simple negative pressure liposuction had the poorest effects.
  
  
  CONCLUSIONS
  The external ultrasonic liposuction operation is a safe and effective method for local overweight reduction.
