Hgns: Metabolic Endpoints For Obstructive Sleep Apnea Following Twelfth Cranial Nerve Stimulation
The purpose of this study is to determine if the treatment of Obstructive sleep apnea (OSA) by hypoglossal nerve stimulation (HGNS) will alter glucose metabolism. The study team will also determine if the treatment of Obstructive sleep apnea (OSA) by (hypoglossal nerve stimulation) HGNS will alter predictors of cardiovascular outcomes.
• Overweight or obese males and females BMI 25 kg/m2 to 40 kg/m2
• Age 18 years and older
• Diagnosed with obstructive sleep apnea by Apnea-Hypopnea Index \>15 events/hr using 4% oxygen desaturation criteria and \< 25% central events/hr on prior sleep testing Data can be derived from home sleep testing or in-lab polysomnogram
• Absent circumferential collapse on Drug-Induced Sleep Endoscopy (DISE)
• Not able to use positive airway pressure \>4 hours for 5 nights/week or unwilling to use positive airway pressure
