    Abstract:
    Fibro-osseous tumors, including osteomas, ossifying fibromas, and fibrous dysplasia, are not uncommon benign lesions arising in the paranasal sinuses. Conventional wisdom advocates resection when these lesions are symptomatic, or when they exhibit rapid growth. Traditionally, resection has been performed via a variety of open approaches. With the advent of sinonasal endoscopy in the mid 1980s, and subsequent advances in technology and surgical techniques, endoscopic management of some of these lesions is now feasible. To date, a search of the literature reveals only three case reports of osteomas resected with endoscopic guidance. We present a series of 10 symptomatic fibro-osseous lesions (nine osteomas and one fibrous dysplasia) occurring in nine patients in which endoscopic techniques were used. Seven ethmoid and frontal recess osteomas were resected transnasally and one sphenoid sinus fibrous dysplasia was resected using a transseptal transsphenoidal approach with the assistance of direct endoscopic visualization. There were two anticipated CSF leaks that were recognized and repaired at the time of surgery. There were no other complications and no tumor recurrence. All patients noted improvement in preoperative symptoms. We discuss patient selection, operative techniques and strategies, and the advantages and disadvantages of the endoscopic approach in the management of paranasal sinus fibro-osseous lesions.
