Abstract

BACKGROUND: Closure of skin and soft tissue defects is a main stream procedure in the field of plastic and reconstructive surgery .Keystone perforator island flap is a curvilinear trapezoidal shape. It is essentially elliptical in shape and it is long axis adjacent and parallel to long axis of defect. We focused in this study specifically on pressure ulcer and traumatic wound as an example of chronic and difficult wounds. OBJECTIVE: To evaluate keystone design perforator island flap as reliable versatile method for closure of soft tissue defect. PATIENTS AND METHODS: In this prospective study,  keystone perforator island flap applied to 11 patients , 7 of them  were pressure ulcer and 4 of them with traumatic soft tissue defect. RESULTS: Keystone flap used in 11 patients in this study , all of patients showed complete flap survival without even minor necrosis, only one patient developed  wound dehiscence ,otherwise all patients showed complete recovery without any sequalae. CONCLUSION: Keystone flap is reliable ,safe ,easy to perform ,cost effective flap, with low rate of flap failure and no donor site morbidity, can be used as effective method of  wound closure even in chronic and unhealthy wound.
