Abstract:
OBJECTIVE:To study the relationship between nasal airway function and severe obstructive sleep apnea-hypopnea syndrome (sOSAHS).
METHOD:One hundred and four cases were divided into 3 groups: group A was 39 normal adult men, group B was 25 nonobese patients with sOSAHS (BMI<28), groups C was 40 obese patients with sOSAHS (BMI > or = 28). Acoustic rhinometry and rhinomanometer was used to acquire unilateral area of first constriction, unilateral area of second of constriction, unilateral minimum cross-sectional area,unilateral nasal volume 0-5 cm, 2-5 cm, the effective unilateral and total nasal resistances in inspiration, expiration at 150 Pa (URins, URexp, TRins, TRexp).
RESULT:Nasal resistance were significantly higher in the group B compared to the group A and group C (P<0.05). Among the group B, but not the group A and group B, we found significant correlations between TRins,TRexp and apnea hypopnea index (r=0.402, 0.401, P<0.05).
CONCLUSION:Nasal resistance is an important factor for nonobese patients with sOSAHS.
