Mucocele of the Paranasal Sinuses – Retrospective Analysis of a Series of Seven Cases

Abstract

Abstract Aim: The present study aimed at identifying the risk factors, typical clinical symptoms and applied treatment in seven cases with mucocele of the paranasal sinuses. Materials and methods: Seven patients suffering from mucocele of the paranasal sinuses were admitted to the Clinic of Neurosurgery and the Clinic of Ear, Nose and Throat Diseases between 2014 and 2016. There were 4 females and 3 males aged between 22 and 78 (95% CI [31.44, 70.23]). Initial symptoms, their duration, clinical presentation upon admission, localization of the mucocele, type of surgical intervention and outcome have all been studied. Results: The localization of the mucocele was frontal (2 cases), fronto-ethmoidal (2 cases), ethmoidal (1 case) and spheno-ethmoidal (2 cases). Risk factors were identified in 4 cases. Endoscopic marsupialization of the mucocele was performed in 5 cases. One patient with intracranial extension of frontal mucocele was treated via right frontobasal craniotomy. One of the patients refused surgery. Conclusion: Endoscopic marsupialization should be considered as a method of choice in cases with mucoceles without extensive intracranial invasion. This approach offers adequate drainage, balloon dilatation of the natural sinus openings that prevents future recurrence.
