A case of giant fronto-ethmoidal osteoma (45 × 42 mm) with intracranial and orbital extension: a case report

Giant sinonasal osteomas are rare tumors. The primary goal of treatment is to completely remove the tumor using a combined endoscopic and external approach. Postoperative morbidity varies depending on the surgical technique used, and there is a risk of recurrence if the tumor is not entirely excised.
