A Salvage Strategy for the Fibula Osteocutaneous Flap Without Traditional Perforator: A Case Report of Peroneal Artery Tibialis Anterior Cutaneous Perforator Skin Paddle.

The fibula osteocutaneous flap is the most commonly used flap to repair jaw defects, which can be used for composite soft and hard tissue reconstruction. Traditionally, the skin paddle of the fibula osteocutaneous flap is based on perforators from the peroneal artery, which is affifixed to the posterior crural septum between the peroneus and the soleus. The anatomy is relatively constant, and the perforators of skin paddle variation encounter in clinical occasionally. The authors report a case of reconstruction of mandible and soft tissue with fibula osteocutaneous flap after extensive radical resection of squamous cell carcinoma of the mouth floor. In this case, the authors raised a skin paddle based on the anterior tibial perforator of peroneal artery from the anterolateral intermuscular septum between the peroneus and the anterior calf muscles, which successfully rescued the traditional perforator absence and avoided exploration for a second donor site.
