Upper airway size is related to obesity and body fat distribution in women.

The aim of this study is to analyze the relationships between obesity, fat distribution and pharyngeal transversal area in women. Cross-sectional areas of the pharynx at the oro-pharyngeal junction and at the glottis and mean pharyngeal area were measured by acoustic pharyngometry in 145 women (age 42.9 +/- 15.

Obstructive sleep apnea syndrome in morbid obesity: effects of intragastric balloon.

Study Objectives: In obese patients, obstructive sleep apnea syndrome (OSAS) is attributed to a reduction in pharyngeal cross-sectional area due to peripharyngeal fat deposition. The effect of weight loss on the size of the upper airways of obese subjects is still unknown. We analyzed the pharyngeal cross-sectional area before and after weight loss in morbidly obese patients with OSAS.
