Head Position	Side	Flow (n=5)	No flow (n=5)	P-value
Upright	Left (Affected)	62.6 ± 7.96	15.2 ± 2.05	0.00010
Upright	Right	223.0 ± 8.97	72.0 ± 6.44	<0.00001
Head Back	Left (Affected)	62.2 ± 7.79	29.0 ± 1.22	0.00056
Head Back	Right	220.0 ± 10.51	109.6 ± 10.01	<0.00001
Mygind’s	Left (Affected)	61.6 ± 7.77	105.6 ± 9.5	0.00005
Mygind’s	Right	219.2 ± 10.03	130.4 ± 9.99	<0.00001

The values were presented as means ± standard deviation and were compared with the Student’s t-test. P-value<0.05 indicate statistical significance (all cases).
