In a patient presenting with epiphora and nasal obstruction, computed tomography disclosed a giant osteoma of the ethmoid. In this article, one patient having giant ethmoidal osteoma with orbital extension is described, and epidemiology, diagnosis, treatment, and pathological findings in paranasal sinus osteoma are reviewed.eninfo:eu-repo/semantics/closedAccessEthmoid OsteomaParanasal SinusNeoplasmsGiantEpiphoraOrbital ExtensionArticle412122124WOS:0001844494000132-s2.0-003774505712868380Q1Q3
