부비동 점액낭종의 임상양상

Background and Objectives: A mucocele is an epithelial-lined, mucus-containing sac completely filling a paranasal sinus and capable of expansion by virtue of dynamic process of bone resorption and new bone formation. It is thought to be secondary to obstruction of the main ostium of the sinus. This obstruction may be the result of inflammation, trauma, osteoma, fibrous dysplasia, or repeated surgery in and around the nasal cavity. Mucocele can occur in any sinuses, but the frontoethmoidal region is most commonly affected. We aimed to evaluate clinical features and treatment results of paranasal sinus mucoceles in Dona-A University Hospital. Patients and Method: We analyzed 46 cases of paranasal sinus mucocele, including postoperative cheek cyst (POCC), which had been operated in Dong-A University Hospital between November 1990 and November 2002. Results: Ethmoid sinus mucocele was most common except POCC. Frontal and ethmoid mucoceles mainly showed ophthalmic symptoms such as exophthalmus, orbital pain, and diplopia, whereas maxillary mucocele mainly showed cheek swelling and nasal obstruction. Endoscopic marsupialization was performed in 20 out of 22 cases except POCC. In most POCCs except 4 cases, endoscopic and Caldwell-Luc approaches were combined. Only 1 out of 46 cases recurred. Conclusion: Ethmoid sinus mucocele was most common except POCC, and mainly showed ophthalmic symptoms. Endoscopic marsupialization was performed in 20 out of 22 cases except POCC, and only 1 case recurred. (J Clinical Otolaryngol 2004;15:93–97)
