A Case of Giant Ethmoid Sinus Osteoma

Abstract

Paranasal sinus osteomas are slow-growing benign tumors. They are generally asymptomatic in most patients and usually diagnosed incidentally with a sinus radiograph or more frequently with a CT scan of the paranasal sinuses. Osteomas can cause various signs and symptoms, depending on the location of the mass. Giant osteomas of the paranasal sinuses are very rare, with only a handful of case reports in the literature. Due to the rarity of giant osteomas, the clinical presentation and treatment are unclear. In this article, we present a case of giant ethmoid sinus osteoma, which was removed with an endoscopic endonasal approach, as well as a review of the literature.
