ETHMOID SINUS OSTEOMA COMPRESSING THE NASOLACRIMAL DUCT

Department of ENT,Hospital of SSK, İzmir, Türkey Abstract Osteoma is the most common benign tumor of the paranasal sinuses, affecting from 0.43% to 1% of the population. Paranasal sinus osteomas are most commonly seen in the frontal sinuses, it is less common in the ethmoid and maxillary sinuses and is almost never seen in the sphenoid sinus. In this article, a female patient with complaints of right sided epiphora and facial pain is represented. A 39 year-old female patient represented with a about 6 months history of right sided epiphora and facial pain that lasted since 1 month. Visual acuity is not affected and intraoculer pressure was within normal limits. An axial and coronal sectioned computed tomography scan of the orbit and paranasal sinuses revealed a large bony mass in the right ethmoid sinus which also blocks the nasolacrimal canal. The osteoma was removed with success through endoscopic sinus surgery. The patients postoperative course was uneventful. Epiphora resolved within days postoperatively. In her follow-up after 1 months, she was without symptoms. Since ethmoid sinus osteoma which compresses the nasolacrimal duct is rare, the case was reported.
