[The gluteal perforator-based flap for repair of refractory wounds on different sites of buttocks].

Objective: To discuss the application of perforator-based flap for repair of refractory sacral, ischial and trochanter wounds.
Methods: Vacuum sealing drainage (VSD) were applied for all the wounds for 6 - 21 days and cutaneous perforator was detected by Doppler before operation. According to the location of the perforator arteries, different types of perforator-based flaps were used to cover the wounds on the buttocks.
Results: Since 2005, 18 wounds in 14 patients were treated, including 11 sacral, 5 ischial and 2 trochanter defects. All flaps survived with primary healing.All the patients were followed up for 2 to 24 months with no ulcer relapse. The colour and texture of the flaps were excellent with satisfactory cosmetic results.
Conclusion: The gluteal perforator-based flaps have reliable blood supply with less morbidity in donor sites. It is an optimal method in repairing refractory wounds of the gluteal region.
