ABSTRACT: Background: Sinonasalosteomas are rare benign tumors that can cause clinical symptoms depending on their size and location. Osteomas are classified as giant osteomas when their size gets larger than three centimeters. In giant osteomas, severe symptoms and complications can occur if they expand into adjacent structures. Aim: In this case report, we highlight the diagnostic importance of CT scans of paranasal sinuses in diagnosing osteomas and the superiority of endoscopic surgery over an open approach in removing these benign tumors. Case Presentation: We report a rare case of giant ethmoidosteoma with extension to intraorbital facilities in 19 years old female which was causing a mass effect on the orbital space and discuss the appropriate management. Conclusion: Ethmoid sinus osteoma is asymptomatic until it increases in size producing a pressure effect on the eyes and sinusitis. CT imaging is the gold standard diagnostic modality. Surgical excision is the treatment of choice for ethmoid sinus osteoma. Due to the size of the lesion, endoscopic surgical excision is a less commonly employed modality, but it has advantages like earlier recovery and cosmetic benefits due to which it was the treatment employed in this case.
