title: [Repair of circular scar in the forearm by expanded double-pedicle omega-shaped flap at the rear flank of bottom-waist].
abstract: OBJECTIVE
  To discuss the method for repairing the circular scar in the forearm.
  
  
  METHODS
  Large expander (400-600 ml) were implanted subcutaneously at the rear flank of bottom-waist in the way of overlapping or continued expansion. After expansion was completed, the horizontal opened omega-shaped flap was formed by advancement of expanded skin with the two pedicles at the two sides. Then the forearm was tunneled under flap with the wound covered by flap. The pedicles were cut off at the third stage.
  
  
  RESULTS
  From April 1998 to June 2009, 8 cases were treated with no flap necrosis. The patients were followed up for 1 to 3 years with good flap color and thickness. Flap sensory was partially recovered. Linear atrophic scar was left in the donor sites.
  
  
  CONCLUSIONS
  It is feasible to repair forearm circular scar by expanded double-pedicle omega-shaped flap at the rear flank of bottom-waist.
