Evolution of sleep architecture and level of alertness measured by MWT in apneic patients treated by genioglossus stimulation (inspire ® therapy)

Introduction: Genioglossus stimulation (Inspire ® therapy) is a novel therapy for patients suffering of obstructive sleep apnea syndrome (OSAS). It has proven its efficacy in reducing apnea-hypopnea index (IAH) but the impact on sleep architecture and level of alertness has been poorly investigated. Thus the aims of this study were: i) to compare sleep architecture and level of alertness before therapy and 6 months after implantation and ii) to explore the relationship between changes in sleep architecture and in level of alertness, in patients with sever OSAS.
