Craniofacial osteomas, which involve orbits, can cause several problems, such as displacement of the globe, diplopia, and refractive changes. We report the case of a young man with diplopia and blurred vision, with a giant osteoma occupying right frontal and ethmoid sinuses, encroaching into his right orbit. The symptoms resolved 3 months after surgery. Our case highlights the successful surgery for a symptomatic craniofacial osteoma with orbital invasion.
