about 1.6 billion people in the world suffer from overweight.
In most cases,
patients with obesity identify obstructive sleep apnea (OSA). OSA is a condition characterized by the presence of snoring,
periodically repeated partial or complete cessation of breathing during sleep,
long enough to lead to lower levels of oxygen blood,
coarse fragmentation of sleep and excessive daytime sleepiness.
The diagnosis of OSA should be made if episodes of apnea last less than 10 seconds at...
Methods and Materials
40 obese males (31 to 66 years) included in the study were divided into 2 groups. OSAS group included 20 patients with body-mass index (BMI) of 35.1±3.4 kg/m 2 and apnea-hypopnea index (AHI) of 54±16. Control group included 20 patients with BMI of 32.0±2.6 and without OSAS (AHI of 2±1) or with light OSAS (AHI of 10±3). All patients underwent MRI using 3T scanner with measurement of the volume of the soft palate (VSP),
the volume of tongue (VT),
the volume of the lateral walls (VLW) of the RP...
Patients with OSAS showed higher values of the volume of tongue (11.8±1.4 vs.
9.1±1.5 sm 3 ),
the volume of soft palate (2.7±0.4 vs.
2.1±0.3 sm 3 ),
the volume of lateral walls at RP region (3.5±0.8 vs.
3.0±0.6 sm 3 ) and the volume of lateral walls at RG region (4.5±0.8 vs.
3.0±0.6 sm 3 ) comparing with the control group,
p<0.05 for all comparisons.
patients with OSAS had lower values of the area of maximum airway constriction at the level of both RP (29±7 vs.
38±11 mm 2 ) and...
Patients with obesity and OSAS have significantly higher volumes of airways soft tissues and lower area of maximum airway constriction comparing with obese patients without OSAS.
These values can be used for OSAS early detection and assessment.
