Endoscopic Endonasal Management of an Ethmoidal Osteoma With Orbital Extension

Abstract

Osteomas are the most common benign tumors of nose and paranasal sinuses. Endonasal endoscopic surgery began to find its place in frontoethmoidal osteoma surgery instead of open procedures. In this paper, an ethmoidal osteoma case with orbital extension totally resected with endonasal endoscopic approach was reported. The patient rapidly recovered postoperatively without any morbidity and with great cosmetic result. There was no tumor recurrence during 7 months of follow-up. When compared with the previously used management modalities, endonasal endoscopic surgery for skull base lesions, including frontoethmoid osteomas, is a newly developing technique of the last century. Clinical experiences show that, in trained hands, this is a safe and effective procedure, by which a radical tumor excision can be possible regardless to its extension in appropriate cases.
