Mucoceles of the paranasal sinus are benign expandable lesions that primarily occur between the fourth and seventh decades of life. In this study, the cases diagnosed with paranasal sinus mucocele who were operated by a single surgeon between 2002 and 2019 were evaluated in terms of symptoms, surgical technique, complications, and recurrence and discussed in the light of the literature. In this study, we retrospectively analyzed 75 patients, 76 mucoceles who underwent operations due to paranasal sinus mucoceles between January 2002 and December 2019. In the patients diagnosed with a mucocele, the mucocele was removed surgically. Of the 75 patients, 36 were female and 40 were male. All the patients were between the ages of 21 and 85, with an average age of 56.9 years old. Mucocele formation occurred in the frontal sinus in 46 (61%) patients, the maxillary sinus in 16 (21%) patients the ethmoid sinus in 11 (14%) patients, and the sphenoid sinus in 3 (4%). 1 patient had both frontal and maxillary sinus mucocele. 15 underwent surgery using external approach. All patients were followed-up with endoscopic examinations for 13 months to 4 years. 4 of 76 mucoceles (5,3%) experienced recurrence Treatment of paranasal sinus mucoceles is surgical and usually simple drainage and marsupialization of mucoceles is sufficient. The endoscopic approach in the treatment of sphenoid, maxillary and ethmoid mucoceles is the surgical method of choice without question. However, in frontal sinus mucocele surgery, external surgery is still valid as much as endoscopic sinus surgery.
