The free fibular osteocutaneous flap is often used in the reconstruction of composite oromandibular defects. In contrast, the lateral calcaneal flap has never been used in oromandibular reconstruction. On the basis of their anatomic continuity, the authors combined the free fibular osteocutaneous flap with the lateral calcaneal skin paddle to obtain 2 adjoining flaps in different anatomic areas with the same vascular axis. The authors report their experience in 3 patients with composite oromandibular defects. In 1 patient without an outer skin defect, only a sensory lateral calcaneal skin paddle with a fibular osseus flap was harvested. The lateral calcaneal flap carried the sural nerve as a sensory flap in 2 patients, and the result was passable. Only 1 patient encountered superficial flap tip necrosis at the lateral calcaneal skin paddle, and recovered well after wound care. In conclusion, a flap with many specific features is a feasible choice for reconstruction of composite oromandibular defects.
