Management of Diffuse Polyposis and Antrochoanal Polyp within Maxillary Sinus Using Microdebrider in Endoscopic Sinus Surgery / 대한이비인후과학회지

ABSTRACT

BACKGROUND: Many studies on the outcome of endoscopic sinus surgery(ESS) reported that patients' symptoms were much improved but surgeons were not so satisfied with endoscopic and radiologic findings postoperatively. One of the reasons may be that it is hard to manage diffuse poyposis(DP) within the maxillary sinus(MS) sufficiently with preexisting techniques. OBJECTIVES: The aim of this study is to introduce a new surgical technique of managing DP and antrochoanal polyp(ACP) within MS using a microdebrider in ESS and to evaluate the surgical outcome with our preliminary results prospectively. MATERIALS AND METHODS: Symptoms, endoscopic and computed tomographic(CT) findings were evaluated in 10 patients with 18 MS's with the mucosa showing DP and six ACP patients, who underwent ESS and were followed up over six months after surgery in our department from November, 1995 through October, 1996. RESULTS: Of the patients with DP, 88.9%, 77.8% and 75.0% reported an improvement in symptoms of nasal obstruction(NO), rhinorrhea and postnasal drip(PND) respectively, and endoscopic and CT findings were improved in 77.8% and 88.9% of the 18 MS's with DP. Improvement in NO, rhinorrhea and PND was observed in 100.0%, 100.0% and 80.0% of the six ACP patients respectively, and both endoscopic and CT findings were improved in 100.0% of the six MS's with ACP. CONCLUSION: This surgical technique using a microdebrider is effective in management of DP and ACP within MS's in ESS.
