Onodi cells represent a type of posterior ethmoid cells in the sphenoid sinus; here, Pneumatisation occurs as a result of posterolateral. In the case reported, a 37-year-old Male patient was referred to our clinic with complaints of approximately 4-5 years of Headaches, nasal congestion and snoring. Paranasal sinus computed tomography (CT) scans showed left isodense lesions exhibiting the isolated Onodi cell. Surgery was planned to remove the Onodi cell mucocele using the endoscopic approach. The Lesion had expanded to completely fill the Onodi cell; lesion was totally removed by Aspiration. Fifteen months postoperatively, the patient underwent CT, and Onodi cells with completely normal aeration were observed. Onodi cells, the optic nerve and the internal carotid artery are in close proximity to one another, and therefore the existence Of Onodi cells are important information. Therefore, elucidating the detailed anatomy of the paranasal sinuses and the recognition of variations amongst them will facilitate accurate diagnosis of patients, as well as physicians’ management of complications which may occur.
