The keystone design perforator island flap. Part II: clinical applications.

Background: This curvilinear- and trapezoidal-shaped flap essentially consists of two conjoined V-Y flaps end to side. The vascular supply is supported by the subcutaneous vascular network and is dependent on fascial and muscular perforators. A review of 15 clinical cases was performed to assess the reliability and versatility of the flap.

The keystone design perforator island flap. Part I: anatomic study.

Background: The keystone design perforator island flap has been described as a curvilinear shaped trapezoidal design flap that is essentially two V-Y flaps end-to-side. Viability of the flap is thought to be supported by the subcutaneous vascular network and fascial and muscular perforators. The aim of this study was to assess the vascularisation of this flap and the behaviour of the skin paddle when submitted to important traction forces.
