Frontal sinus mucocele usually presents with frontal headache and frequently with proptosis as well as diplopia. These cases over the years have required either conservative or radical surgical procedure. However, recently functional endoscopic
sinus
surgery affords the potential to decrease the operative morbidity of surgery by direct endoscopic visualization under local anesthesia. Besides, it makes it possible to solve the problems of visualizing the operative area after surgery, and
releives the
difficulty of imaging the sinus radiographically after an obliterative procedure.
We have experienced a case of frontal sinus mucocele which was satisfactorily treated under endoscopic approach. Following surgery, no disease recurrence has been noted to date with endoscopic and radiologic follow-up of up to 7 months. The
etiology,
presenting features, and treatment of this mucocele were reviwed. (Korean J Otolaryngol 38:8, 1995)
