Complicated Giant Mucoceles of the Frontal Sinus: Approach to Endoscopic Marsupialization Technique

Abstract

A number of external and radical procedures have been the only surgical approaches for the treatment of frontal sinus mucoceles. However, these procedures have major complications including high surgical morbidity, esthetic concerns of postoperative scar formation, and difficulty in radiologic diagnosis of recurrence after obliteration. In this clinical report, we demonstrated an endoscopic marsupialization technique that could easily be applied to a very large mucocele that has extended to the intracranial region, without any serious complications.
