[Liposuction using a rotary cannula. Technical note].

The liposuction with a rotary cannula combines suction under traditional depression with rotation of the cannula mounted on a hand-piece, connected to a motor. This rotation, which can be has high as 400 r.p.m., allows 360 degrees treatment of lipodystrophy in a single procedure. Safety is ensured by an adjustable couple limiter, which prevents any risk of accidental movements when the cannula meets resistance. The authors conducted a study on 2 cases, which demonstrated a definite advantage of this technique in marked to severe lipodystrophy (1.5 to 7 litres of suction) and in high-density zones which are difficult to treat (epigastrium, knees, dorsal folds). This technique does not provide any decisive advantages in cases of minor lipodystrophy, which could justify its routine use in this context.
