OBJECTIVE To evaluate the clinical efficacy of thin flap with subdermal vascular network of the neck-pectoral region on repair of the contracture of the burn scar on the neck. METHODS From March 1990 to May 1998, 21 cases of deformity of neck due to burn scar were repaired with the thin flap ranging from 8 cm x 5 cm to 14 cm x 8 cm, and all of the cases were followed up for 6 to 42 months. RESULTS Except partial necrosis of the distal end of the flap in 1 case, the flaps in the other 20 cases all survived and presented a satisfactory appearance and function. CONCLUSION The thin flap with subdermal vascular network in neck-pectoral region may provide a large area of flap, and could be easily transferred. It’s an ideal flap for the repair of skin defect on the neck.
