Abstract
Osteoma located in the paranasal sinus is a slow growing benign tumor. It commonly occurs in frontal, ethmoid and maxillary sinuses in the order of frequency. Giant osteoma is very rare in the pediatric population, and only nine cases of giant osteoma are reported till date in the form of isolated case reports. Authors report a giant spheno-ethmoidal osteoma in a 14-year-old boy, who presented with progressive visual impairment and proptosis of the left eye for last 1-year. Total excision was carried out using transcranial extradural approach. The postoperative recovery was uneventful and showed remarkable visual recovery along with cosmesis.
