Imaging Findings in Patients with and without Rhinorrhea.

	Rhinorrhea present (N = 2)	Rhinorrhea absent (N = 53)	Total (N = 55)†	P-value*
Sinus disease, N (%)	0 (0)	23 (43.4)	23 (41.8)	.50
Number of sinuses involved, median (IQR)	-	1 (1-3)	1 (1-3)	-
NP thickening, N (%)	2 (100.0)	27 (51.9)	29 (53.7)	.49
Olfactory recess opacification, N (%)	0 (0)	4 (7.7)	4 (7.4)	1.00
Mastoid opacification, N (%)	0 (0)	4 (7.5)	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.
