Fibroma osificante de seno etmoidal con invasión orbitaria: a propósito de un caso

Sixty-four cases of neoplastic benign fibro-osseous lesions are presented, with clinical and radiographic follow-up in 23 instances. A marked predilection for female patients was observed, with the majority or cases arising in the molar-premolar region of the mandible. Radiographically, these neoplasms are well demarcated and may be radiolucent, radiolucent with central opacification (target appearance), or multilocular radiolucent. A benign fibro-osseous histopathologic pattern is observed with osseous, cemental, and/or ovoid-curvoid calcified deposits. This feature, along with confinement to tooth-bearing regions, supports a periodontal ligament origin. It appears that the distinction between cementifying and ossifying variants is academic, as no behavioral differences exist. The recurrence rate following curettage was found to be 28%.

The purpose of this study was to evaluate the clinical outcomes of ossifying fibroma (OF) in a group of 14 patients treated in our clinic and discuss the management and the prognosis of this tumor. The study included 14 consecutive patients with OF of the jaws with ages ranging from 7 to 55 years. Primary site distribution was maxilla (1), maxilla, maxillary sinus (1), and mandible (12). All of the patients treated by surgery (curettage, enucleation, or radical surgery). The mean follow-up range was 2-18 years. All of the patients were alive and disease free. OF is a benign slow-growing tumor of the jaws. Early tumors that are small or well demarcated are treated by curettage or enucleation. For aggressive tumors that show rapid enlargement, radical resection (maxillectomy or segmental mandibulectomy) is used. By either method of treatment, the recurrence rate is extremely low.

The purpose of this work was to perform a systematic review regarding ossifying fibroma and its multiple variants of the paranasal sinuses, and to identify any clinical differences between the multiple variants.
