Abstract

Osteoma is the most common benign tumor of the paranasal sinuses and the frontal sinus is the most frequently involved site. Osteomas are slow growing osteoblastic lesions commonly seen in the outer table of the calvarium, the mandible, the frontal and ethmoid sinus, and occasionally in tubular bones. They are usually detected during the second to fifth decades of life, and reported ratio of male to female is 1.5:1 to 2:1. The symptoms of osteomas are usually developed as gradual growth. They are headaches, facial pain, proptosis, decreased visual acuity, chemosis, diplopia, epiphora, nonpulsating exophthalmus, and transient blindness. Posterior intracranial extension of a frontoethmoid osteoma may lead to brain abscess, intracranial mucocele, tension pneumocephalus. We experienced a 60-year-old male patient who came to the emergency room with acute and severe left periorbital swelling, red eye, and epiphora lasted for 10 days. In a plain radiographs and computerized tomographic scans, a 2.5 x 2.5 x 3.0 cm well marginated mass impressed by osteoma in frontoethmoidal sinus was detected. After the symptoms subsided by conservative treatment, total excision was made by bicoronal approach. Authors reported a frontoethmoidal osteoma presenting periorbital cellulitis without orbital mucocele, which is very rare symptom.
