Background

Almost all cystic fibrosis (CF) patients reveal upper airway involvement in computed tomography (CT) scans. Sinonasal pathology has become a challenging issue because there are few studies to guide appropriate management. The objective of this study was to provide information about paranasal sinus CT manifestations in CF patients, mainly in adulthood.

Methods

We performed a literature review of descriptive studies about CT sinonasal findings in CF patients using the following databases: MEDLINE, EMBASE, Web of Science, LILACS, Scielo, and Cochrane.

Results

Eighteen articles were included in this review. There was a high variability in methodological aspects for most of the studies. The most prevalent findings reported were opacification of sinuses, presence of frontal and sphenoidal aplasia or hypoplasia, underdevelopment of paranasal sinuses, and medial bulging of the lateral nasal wall in CT scans.

Conclusion

There are few studies in the CF adult population regarding sinonasal CT alterations. Many studies report specific pathological features in CF upper airways that could help in the diagnosis of doubtful cases.
