Over the years, many radical and conservative procedures have been recommanded for the treatment of paranasal sinus (PNS) mucocele. However, the postoperative visualization of these slow growing lesion is a problem. Even with the highly advanced imaging techniques of computerized tomography and magnetic resonance imaging, it is difficult to image and evaluate the sinuses for recurrence / persistence of a mucocele after an obilterative procedure. Preservation of the mucocele mucosa with marsupialization of the mucocele has been advocated for over 70 years by many authors. With the recent advent of imaging techiniques and development of nasal endoscopes, functional endoscopic sinus surgery affords the potential for dramatically reducing the morbidity involved in treating mucocele, because it provides a minimally invasive approach under local anesthesia. We treated 7 patients of PNS mucocele endoscopically, with a dramatic reduction of morbidty. With telescope, the entire operation could be performed under direct visualization and no recurrence has been noted with endoscopic follow-up up to 22 months after surgery.
