title: Benign osteoblastoma of the maxillary sinus.
abstract: Benign osteoblastoma is an uncommon fibro-osseous neoplasm with a predilection for the vertebrae and long bones, and a 2-to-1 male-to-female ratio of occurrence. Peak incidence occurs in the second decade, with 80% of all patients being under 30 years of age. The clinical, radiographic, and histologic presentation of a large maxillary sinus osteoblastoma is reviewed. Preoperative embolization of this vascular neoplasm is advocated.
