만성 부비동염 환자에서 임상증상 및 전산화단층촬영 소견에 의한 부비동 내시경수술의 술후 결과분석

Endoscopic sinus surgery is based on principle that the mucosal abnormalities can be reversed into normal mucosa by relieving the obstruction of the anterior ethmoidal area. This study is aimed to evaluate postoperative mucosal changes and symptomatic improvement in the patients who have underwent endoscopic sinus surgery from September 1991 through August 1992. The total number of patients were 76, who were divided into 2, 4, and 6 months postoperative groups. The thickness of maxillary sinus mucosa measured at three different sites on follow-up ostiomeatal unit(OMU) computed tomogram was compared with that on preoperative OMU CT. Changes of preoperative symptoms such as nasal discharge, nasal obstruction, facial pain, headache, anosmia and epiphora were analysed. It is suggested that removal of obstructive lesion in the ostiomeatal area might be beneficial in symptomatic improvement, however, healing of the maxillary sinus mucosa might take longer than 6 months after operation.
