Abstract

BACKGROUND AND OBJECTIVES: Concha bullosa is one of the most common obstructive anatomical variants seen in patients with sinusitis. We wanted to illustrate the relationship of the contents and CT findings of concha bullosa, and of the contents of concha bullosa and the lesion at the origin site of concha bullosa. MATERIAL AND METHODS: We evaluated PNS CT of 1023 patients with sinusitis, and a total of 172 patients with concha bullosa were evaluated to study the contents and origin site of concha bullosa by CT and endoscopic findings and pathologic confirmation of the contents.
RESULTS
Contents of the concha bullosa were normal mucosa in 29.2%, mucosal thickening 26.0%, mucopurulent discharge 35.6% and polyp 9.2%. Although CT findings and the origin site of concha bullosa were normal, the diseased concha bullosa were 30.1% and 23.0%.
CONCLUSION
Regardless to the presence of disease at the origin site and CT findings of Concha bullosa, we found it necessary to validate concha bullosa.
