Objective To investigate the operative technique and clinical effect of perforator-based flap for repair of glutealsacral skin defects. Methods A new perforator-based flap derived from the gluteal, parasacral and the lumbar arteries was used to repair skin defects ofglutealsacral region caused by trauma or pressure sore. The flap areas ranged from 6 cm×5 cm to 19 cm×11 cm, the diametre of perforating vessel ranged from 1.3 to 2.1 mm,the length of free perforating vessel pedicle ranged from 2.5 to 4.5 cm.Results All the flaps survived andthe wound gained primary healing. All the patients were followed up for 6 to 24months. The colour and texture of the flaps were excellent, the configuration was satifactory and there was no ulcer recurrence. Conclusion This new type of flap is characterized by delicate design, easy dissection, reliable blood supply, nosacrifice of the underlying muscle and no requirement skin graft for donor site closure. It is an optimalmethod in repairing soft tissue defects of the gluteal-sacral region. 
