About

Evaluation of upper airway with Magnetic Resonance and polysomnographic at the pre and post operative of 23 women having undergone bariatric surgery (with the Y-Roux technique) for treatment of obesity.

Full description

The the present study aims at describing the modifications occurring in the upper airway (UA) and the impact of such modifications on the severity of obstructive sleep apnea after bariatric surgery in women who have obstructive sleep apnea (OSA). The hypothesis is that the massive weight loss after bariatric surgery on OSA women could modify the UA more intensely than previously reported by other therapies for weight loss and that the menopause status may influence the likely reshaping of UA after bariatric surgery.
