The authors report a case of cemento-ossifying fibroma of the superior maxillary bone, which invaded the maxillary sinus bilaterally. Surgery was performed by an intraoral incision on the left and the arrangement of a flap according to Weber-Fergusson on the right. Histologic features and the investigations required to reach a correct diagnosis are described. A 12-month follow-up showed a complete restitutio ad integrum with a normal pneumatization of the maxillary sinuses and satisfactory residual scarring. It is a fibro-osseous lesion, with a slow growth, which can lead to a deformity of the affected bone resulting in aesthetic and/or functional alterations. Descriptions of bilateral cemento-ossifying fibroma are uncommon. The differential diagnosis must be determined with other pathologies, such as chronic osteomyelitis, periosteitis, Paget’s disease, hyperparathyroidism, osteoblastoma and low grade osteosarcoma. The prognosis is excellent and relapses are uncommon.
