Background:
Frontal sinus mucoceles are known to undergo repeated recurrences, and the management of this disease constitutes a challenge regarding the ideal treatment. The aim of this study was to evaluate the postoperative results of the endoscopic ventilation approach in the treatment of frontal mucoceles.
Methods:
We retrospectively reviewed the charts of 24 subjects with mucocele who underwent endoscopic marsupialization. The preoperative characteristics of the frontal sinus on computed tomography scans were compared with the postoperative results.
Results:
Postoperative endoscopic examination revealed in 15 nasal sides wide patency of the frontal outflow tract. The ostium was patent but had become slightly narrowed in nine nasal sides. Restenosis of the ostium was found in six cases.
Conclusion:
A membranous type of obstruction in the region of the frontal outflow tract was related to a better outcome.
