【 摘 要 】

Sinonasal polyposis (SNP) is a condition with a controversial aethiology, known by bilaterally inflammatory mucous membranes of nasal and paranasal sinuses. The major patient's complaint is nasal obstruction, and polypoid masses in different sizes can be found during nasal cavity examination. Beyond anterior rhinoscophy and nasal endoscopy, screening sinus computed tomography (SSCT) is necessary to measure the size and the extent of the polyps into nasal cavities and paranasal sinuses. The purpose of this study is to evaluate the concordance between two observers through SSCT of 32 cases with SNP.STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: CT scans were evaluated separately by two experts, taking into consideration three suggestive tomography signs of SNP: (1) Infundibular enlargement of ostiomeatal complex; (2) bulging of lamina papyracea and (3) bony attenuation of ethmoid trabeculae. RESULTS: Qui-square was not significant for either the first or the second signs (p=0,7055 and p=0,2057), but for the third one (p=0,0040). However, Kendall coefficient between the two observers was significant for all the three tomography signs mentioned before (p<0,001; p=0,01; p=0,03). CONCLUSION: The major concordance between the observers concerned the infundibular enlargement, which was also the most frequent sign.
