[Ethmoid sinus osteoma with orbital invasion: report of three cases and review of the literature]. / Osteoma do etmóide com invasão orbitária: relato de três casos e revisão da literatura.

We report three rare cases of ethmoid osteoma extending to the medial quadrant of the orbit that had singular particularities, such as occurring in women, at an unusual age group, and complaint of epiphora. The radiographic images were typical of this condition. Patients were submitted to surgery with complete resolution of the disease.
