    Abstract:
    Facial defect after an extended total maxillectomy is one of the most difficult deformities to reconstruct aesthetically, because the defect is not only large but also three-dimensional. Although free-flap reconstruction is useful, the patchwork-like scar, bad colour match and poor texture match are major problems. The contracture and displacement of the reconstructed eyelids and eye socket are also serious matters. To resolve these problems, we have performed a three-step reconstruction using a free rectus abdominis myocutaneous (RAM) flap and an expanded cervicofacial flap with cartilage grafts. In the first step, a free RAM flap was transplanted to the defect after extended total maxillectomy. In the second step, tissue expanders were placed under the skin of the cheek and neck a year after the RAM flap transplantation. After expansion of the cheek and neck skin, the third step was performed. The inferior part of the external skin island of the RAM flap was raised and sutured to the superior margin of the skin island to create a pouch for the eye socket. Costal cartilage was grafted to reconstruct the orbital floor and malar prominence, and auricular cartilage was grafted to reconstruct the tarsal plates. Finally, the expanded cervicofacial flap was rotated to cover this construct. Two weeks after reconstruction, the neo-eyelids were divided to form the lid fissure. We performed the three-step reconstruction on six cases after extended total maxillectomy. In all cases, a deep and stable eye socket was reconstructed. The reconstructed eyelids and cheek were natural in appearance with good colour and texture match without conspicuous scars. To obtain symmetry and natural appearance in the orbitomaxillary reconstruction, there are five points that should be formed; the eye socket, the groundwork of the eye socket, the orbital floor and malar prominence, the tarsal plates and the surface of the eyelids and cheek. We do not reconstruct the palate to set prosthetic dentures and to clean the surface of the skin island in the nasal cavity. To reconstruct the indispensable five points and achieve satisfying results, we propose this three-step reconstruction.
