This study aims to investigate the possible relationship between passive rhinomanometry measurements in sitting and supine position and obstructive sleep apnea syndrome. Between January 2011 and December 2013, 88 male patients (mean age 46.8 years; range 18 to 79 years) underwent passive rhinomanometry in sitting and supine position following history, physical examination and fiberoptic endoscopic examination. 1.5 lt/sn air flow was pumped into the nose of each patient via a silicone nasal mask. Meanwhile, flow and pressure values were measured. There was no correlation between the resistance values and apnea hypopnea index (AHI) scores and polysomnography and physical examination parameters (p>0.05). The differential resistance was correlated with AHI (r=0.325, p<0.05), body mass index (r=0.324, p<0.05), neck circumference (r=0.421, p<0.01), waist circumference (r=0.444, p<0.01), modified Mallampati score (r=0.356, p<0.05), and retropalatal grade (r=0.438, p<0.01). The correlation between the differential resistance and physical examination parameters and AHI scores support the hypothesis that position-related retropalatal segment alterations can be measured by passive rhinomanometry while awake.
