Imaging Findings in Patients with and without Nasal Congestion.
| Nasal congestion present (N = 1) | Nasal congestion absent (N = 54) | Total (N = 55)† | P-value* | |
|---|---|---|---|---|
| Sinus disease, N (%) | 1 (100.0) | 22 (40.7) | 23 (41.8) | .42 |
| Number of sinuses involved, Median (IQR) | 3 (3-3) | 1 (1-3) | 1 (1-3) | .36 |
| NP thickening, N (%) | 1 (100.0) | 28 (52.8) | 29 (53.7) | 1.00 |
| Olfactory recess opacification, N (%) | 1 (100.0) | 3 (5.7) | 4 (7.4) | .07 |
| Mastoid opacification, N (%) | 0 (0) | 4 (7.4) | 4 (7.3) | 1.00 |
Abbreviations: IQR, interquartile range; NP, nasopharyngeal.
†
Due to missing data, for NP thickening, N = 54, and for olfactory recess opacification, N = 54.

For categorical variables, Fisher’s Exact test was used. When median (interquartile range) is presented, Mann–Whitney U test is used.
