Porcine experimental model for gracilis free flap transfer to the head and neck area with novel donor site description

摘要

Introduction: Functional free tissue transfer in the form of muscle free flap is a challenging surgical procedure and needs a steep learning curve. A porcine model for free muscle transfer and insetting in a distant area is of great interest in reconstructive microsurgery due to the experience and learning curve necessary to perform these surgeries. The aim of this study was to assess the feasibility of a swine model for gracilis muscle free transfer and to describe the donor site anatomy.
