Osseocutaneous radial forearm flap with beavertail modification; a case report of a novel, single, reconstructive free flap for the tongue, floor of mouth and mandible

INTRODUCTION Complex hard and soft tissue defects produced as a result of ablative resection of head and neck malignancy can represent a reconstructive challenge, especially when patients are medically compromised. PRESENTATION OF CASE We present the case of 72-year-old women presenting with an oral squamous cell carcinoma of the right floor of mouth invading the right mandible. Surgical management of the disease required ablative surgery with complex free tissue transfer reconstruction to provide restoration of form and function. Potential reconstructive options were limited by her medical comorbidities and poor vessel patency in the lower limbs, requiring novel thinking and adaptation of established techniques. DISCUSSION We describe the first reported use of an osseofasciocutaneous radial forearm flap with a 'beavertail modification' to provide a single and combined reconstructive option to reconstruct a complex hard and soft tissue defect. CONCLUSION This novel free-flap technique adds to the reconstructive armamentarium of the head and neck surgeon.
