Abstract

Osteoma of the paranasal sinuses is found in approximately 0.25% of routine roentgenographic sinus examinations and are most commonly found in the frontal sinus(ethmoid sinus and maxillary following in that order).
Osteomas are classified as compact, cancellous, or mixed, Compact osteoma is an ivory-hard tumor, probably formed by periosteal osteoblasts. To assess growth, a radiographic follow up within 1 to 2 years is necessary. The most frequent site of origin would seem to be the space between the frontal and ethmoid bones.
Nasal stuffiness may be a complaint if the upper lateral nasal wall is displaced medially.
Traditionally, the external ethmoidectomy approache is the route of choice for removal of osteoma of the ethmoids.
In this study, authors present a case of ethmoid osteoma hat was removed successfully through an endoscopic approach.
