Huntley C, et al. - Authors assessed a cohort of patients undergoing upper airway stimulation (UAS) for treatment of obstructive sleep apnea (OSA). They also evaluated the impact of body mass index (BMI) on surgical and quality of life outcomes. Findings suggested success of upper airway stimulation therapy in the treatment of patients with obstructive sleep apnea, unable to tolerate continuous positive airway pressure (CPAP), and with an elevated body mass index (BMI). No difference between raised and nonelevated BMI cohorts in postoperative apnea-hypopnea index (AHI), O₂ desaturation nadir, daytime sleepiness, rate of surgical success, or rate of cure was seen while defining an elevated BMI as greater than 32.
