RESUMO
<p><b>OBJECTIVE</b>To evaluate the role of buccal-fat-pad flap in the lined coverage of the maxillary bone graft for the maxillary reconstruction after the tumor excision.</p><p><b>METHODS</b>Based on the cadaver anatomical observation of the buccal-fat-pad, 38 patients with the maxillary tumors were undertaking the treatment in this paper. Under general anesthesia, the buccal-fat-pad flap was elevated and transferred to the anterior or nasal cavities as a line of the sinus after the tumor was immediately excised through an intro-oral or external approach. The bone from the ribs was then grafted in the place for the maxillary support.</p><p><b>RESULTS</b>After the anatomical evaluation, 38 patients were carried out the operation successfully. All of the grafted bones were well covered without bone exposure. The aesthetic appearance was achieved.</p><p><b>CONCLUSION</b>Bone graft lined by the pedicled buccal fat pad flap may be a safe and good method for reconstruction of the maxilla with a lower rate of re-absorption and sequestration.</p>
