Endoscopic resection of large sinonasal ossifying fibroma.

Fibroosseous lesions of the maxilla and paranasal sinuses differ from one another in their prognosis and treatment, with the most important distinction being that of an ossifying fibroma (OF) and fibrous dysplasia. A clinically significant OF with its potentially more aggressive behavior must be completely resected. A look at historical and current approaches along with a case report of a 19-year-old woman with a recurrent sinonasal OF removed using endoscopic techniques are discussed. The case adds to the growing amount of literature showing a successful alternative to open surgery for large benign sinonasal tumors, when the character of the tumor, desire of the patient, and expertise of the physician permit endoscopic resection. With the improving techniques of sinonasal endoscopy, better care can be provided with less invasive surgery resulting in less recovery time, more aesthetically pleasing results, and decreased potential for infection.
