BACKGROUND: Head and neck ossifying fibroma (OF) is a rare, benign, locally aggressive, fibro-osseous tumor. The mandible is the most common site of involvement, followed by the maxilla, and, less frequently, the sinonasal cavities, orbit, skull base, and calvarium. In this study, we aimed to expand our understanding of this entity by presenting a case series of OF that involved the maxilla and sinonasal tract.
METHODS: A multicenter retrospective review was performed on all the patients with a diagnosis of OF from 2004 to 2013. Data were collected with respect to age, sex, clinical presentation, treatment, and outcome.
RESULTS: A total of 13 patients were identified. The mean age was 37 years, with a female predominance (69%). The maxillary sinus was most frequently involved site (46%). Eighty-five percent underwent open surgical resection. After a mean follow-up time of 47.3 months, three patients (23%) developed recurrent disease; all of whom were treated with an open approach.
CONCLUSION: Of the maxilla and sinonasal tract is an uncommon clinicopathologic entity. Although a timely diagnosis may obviate the need for external approaches, open surgical resection is often still necessary for management of extensive lesions. Close follow-up and additional surgery may also be required to treat recurrent disease.
