Mucoceles are the chronic cystic lesions of the paranasal sinuses. They can cause impression to the around tissues despite their benign nature. The patients with frontoethmoid mucocele that extended to the orbit may have complaint with outer pushing of the eye, diplopia and headache in general. For the treatment of mucocele, according to clinical situation of the patient, the external approach or recently advised endoscopic endonasal marsupialisation approach can be performed. We presented a case of frontoethmoido-orbital mucocele that extended to the orbit by destruction of lamina papyracea. No recurrens observed on clinical follow up. The clinical features of the patient and surgical management were discussed with the literature.
