    Abstract:
    The double free flap procedure is a preferred treatment for extensive composite defects of the oromandibular area. In this procedure, the choice and use of the flaps are both important. Flaps with adequate soft tissue are required to fill the extensive dead space for huge oromandibular defects. Such flaps, however, tend to sink and droop with time because of gravity, resulting in poor functional and aesthetic results. Here, the authors describe a procedure that avoids flap sinking and drooping, using a vascularized fibular osteocutaneous flap, which is well established for mandibular bone defects, and a rectus abdominalis musculocutaneous flap, which has a lot of soft tissue and a firm anterior rectus sheath. This method was used in 2 patients with extensive composite defects of the oromandibular area. In a patient with resection of the mobile tongue and oral floor, the anterior rectus sheath was fixed to the fibula and mandible to give a mylohyoid muscle-like structure, to prevent sinking of the reconstructed oral floor and tongue. Good swallowing function was maintained. In a patient with defects transversally from the submandibular region to the cheek, the sheath was fixed to the zygomatic arch to prevent cheek drooping. An acceptable aesthetic result was obtained.
