P.004 Endoscopic frontal osteoma removal

Abstract

Osteomas are uncommon, slow-growing, benign osteogenic neoplasms that arise most frequently in the craniofacial skeleton.1, 2 Osteoma is the most common benign tumor of the nose and paranasal sinuses and the most common neoplasm of the frontal sinus.3, 4, 5 Paranasal sinus osteomas originate in the sinus wall, fill the lumen with well-defined mature osseous tissue, and occasionally extend into the orbit where they give rise to orbital signs and symptoms. Osteomas most commonly become symptomatic in the second to fifth decade in life, but orbital involvement has rarely been reported in patients aged 18 years and younger.2, 6, 7, 8, 9, 10 We report a case of a frontal sinus osteoma with orbital extension in a 13-year-old girl.
