Rodrigo P. Santos Luiz H. F. Barbosa Marco A Belfort Ricardo G. Ferri Luiz C. Gregorio About the authors

Introduction: The mucocele is an expansive benign tumor due to the filling of a closed cavity with mucus. Frequently involving the fronto-ethmoidal sinus, it is a rare otolaryngological condition. The etiology is divided into inflammatory and obstructive causes. Aim: To evaluate the endoscopic endonasal surgical approach for fronto-ethmoidal sinus mucoceles. Study design: Clinical prospective. Material and method: Thirteen patients were followed during the period of January of 2000 to April of 2001, regarding the clinical findings, evolution and surgical results. Results: All patients presented proptosis as the major symptom. Seven patients had the inflammatory form and two the obstructive one. Two patients presented ophthalmologic complications and underwent orbital decompression associated with the endoscopic endonasal technique. There were no recurrences in our study. Conclusions: The endoscopic endonasal approach for fronto-ethmoidal sinus mucoceles is an effective treatment for the disease, avoiding the complications of the early techniques.
