Abstract
Background: We recorded all cases presenting with paranasal sinus cysts to draw attention to those with unusual presentations and their management outcome in a retrospective original study. Methods: All patients were subjected to history-taking, ENT examination, endoscopic examination, CT scanning, and managed with endoscopic sinus surgery/or a combined approach. Results: We encountered 54 patients with paranasal sinus cysts. Mucocele/pyocele was the commonest (79.6%), followed by radicular cyst (9.3%), dentigerous cyst (5.55%), and fungocele (5.55%). The frontal sinus was the commonest sinus of cyst origin (55.6%). Maxillary sinus cysts occurred in 16.6% of cases. The sphenoid sinus was the "least" sinus of cyst origin in 7.4% of cases. Conclusion: Ethmoid mucocele occurred mostly by extension from other sinuses, predominantly frontal. With exclusive frontal sinus cysts, it is essential to look for possible underlying pathology or associated complication. Fungocele, a new nomenclature, could complicate those with allergic fungal sinusitis.
