P value	< 0.001*	< 0.001*	0.210**
Female
Normal Sinusities	6.30 (5.50–7.30) 5.50 (4.75–6.40)	2.06 (1.83–2.43) 2.86 (2.36–3.46)	47.71 ± 8.66 46.61 ± 7.47
P value	< 0.001*	< 0.001*	0.174**
Male
Normal Sinusities	6.20 (5.40–7.20) 5.50 (4.72–6.57)	2.13 (1.80–2.40) 3.06 (2.46–3.70)	48.88 ± 9.16 48.07 ± 8.08
P value	< 0.001*	< 0.001*	< 0.365**

The length and width values are the median values (first quartile-third quartile)

Significant level is P < 0.05
