Purpose: To report an unusual case of frontal sinus keratocyst.
Case Report: A 31 year old woman presented with a history of swollen right eye and visual field impairment. The ophthalmological examination revealed right superior eyelid edema and some degrees of proptosis. CT scan with iodine injection evidenced the opacification of the right frontal sinus with superior orbital wall lysis. Complete endoscopic surgical resection of a mass containing foul smelling keratin material was performed via Draf type III. The patient became symptomatic after 6 years. Imaging studies showed neo- osteogenesis in the far lateral end of right frontal sinus. Frontal trephination was done and the remnant of keratocyst was removed and the septum interfacing the cell and the right frontal sinus was walled down entirely.
Conclusion: Although frontal sinus keratocyst is benign but can spread to the surrounding structures leading to several complications. Therefore, complete surgical resection is necessary to avoid recurrence.
