Endoscopic Surgery for Paranasal Sinus Mucocele / 대한이비인후과학회지

ABSTRACT

BACKGROUND: Mucoceles of the paranasal sinus are slowly expanding epithelial lined lesions containing inspissated mucus that may erode bone and extend intraorbitally or intracranially. Mucoceles are thought to arise as a result of obstruction of the sinus ostium secondary to inflammation, fibrosis, trauma, previous surgery, or a mass lesion. Mucoceles most frequently arise from the frontal sinus and anterior ethmoid air cells, presenting with proptosis, frontal headaches, and reduced ocular mobility, especially on upward gaze. OBJECTIVES: The surgical approach to paranasal sinus mucoceles has followed two lines. The first is radical exenteration of the mucoceles and its whole lining: the other is marsupialization, leaving part of the lining intact. MATERIAL AND METHOD: This paper was analyzed 9 cases of paranasal sinus mucoceles which had operated in Chonbuk National University Hospital between January 1992 and August 1996. Eight cases were treated via intranasal endoscopic sinus surgery and one case via extranasal approach. RESULTS: There were no significant complications following surgery with a follow-up of 5 months to 2 years. CONCLUSION: So, we report the clinical findings, surgical treatment of 9 cases of mucoceles with review of literature.
