Frontal Mucocele Compressing the Eyeball

Abstract

The mucocele is a cystic pseudotumor that is caused by accumulation of mucus secretion and epithelial desquamation of paranasal sinuses. The most common risk factors in the mucoceles are chronic infection and sinus allergy. Previous surgeries and trauma are less common. Other possible causes may be associated with chronic stimulation of inhaled irritants, viral infection, overdose or gene interaction of the reticuloendothelial system. There is a case of a patient whose final diagnosis was mucocele, which compresses the eyeball and causes paralysis of the upper branch of the third eye nerve due to compression, and which yields after removing the frontal benign tumor with supraorbital commitment.
