Repair of circular scar in the forearm by expanded double-pedicle Ω-shaped flap at the rear flank of bottom-waist

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 Ω-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 for1 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 Ω-shaped flap at the rear flank of bottom-waist.
