Endoscopic Management of Frontal Mucocele Causing Orbital Displacement

A mucocele of paranasal sinuses is a chronic cystic lesion that can either develop from obstruction of the sinus ostium by various pathologies, or from obstruction of the duct of a minor salivary gland located within the lining of the paranasal sinus. Endoscopic Sinus Surgery (ESS) is a minimally invasive technique that has limited implication in dealing with orbital complication. We are presenting a case of frontal mucocele, with secondary orbital displacement, which successfully treated with ESS.
