Benign lesions of the frontal sinus

Benign tumors of the frontal sinus including fibro-osseous lesions and inve rted papillomata present unique problems for the rhinologist. Because of th e bony cavity surrounding: the frontal sinus and relatively small portal in to the nose, conventional techniques including the osteoplastic flap, front al trephination, and lynch procedure have provided useful approaches to the se tumors. The advent of endoscopic techniques in the management of chronic inflammatory disease of the paranasal and, specifically, frontal sinuses, has led to these traditional techniques being augmented successfully, and, in some cases, surpassed by newer endoscopic techniques. This article revie ws the diagnosis and management of the two most common types of benign tumo rs of the frontal sinus, bony tumors and inverted papillomata, with emphasi s on the usefulness of the endoscope in managing such lesions.
