Relationship between the endoscopic, radiological, and operative findings in sinonasal polyposis

Abstract

Abstract Objectives: The aim of the present study was to assess the correlation between preoperative endoscopic, radiological, and operative findings of sinonasal polypsis. Materials and methods: A total of 30 patients with sinonasal polypsis underwent preoperative endoscopic assessment using the Meltzer staging system, radiologic evaluation using the Lund–Macky staging system, and operative evaluation during functional endoscopic sinus surgery using the Meltzer staging system, and findings in each sinus (polyp, fungal mud, mucous, and normal) were recorded. Results: There was a highly significant positive correlation between preoperative computed tomography (CT) and operative findings [right (RT) side=0.731 and left (LT) side=0.814, P<0.001]. There was also a highly significant positive correlation between the preoperative endoscopic and operative staging scores (RT side=0.892 and LT side=0.827, P<0.001). Furthermore, there was a highly significant positive correlation between preoperative endoscopic and CT staging scores (RT side=0.768 and LT side=0.782, P<0.001). Conclusion: No single procedure can be sufficient in accurately diagnosing nasal polypsis, and both the preoperative CT and the preoperative endoscopic examination are complementary to each other.
