[New therapy for sleep apnea at CHUV: hypoglossal nerve stimulation]

Neurostimulation of the hypoglossal nerve is a new alternative treatment to CPAP (Continuous Positive Airway Pressure) for patients with moderate-to-severe OSAS (Obstructive Sleep Apnea Syndrome) with anteroposterior pharyngeal obstruction visualized during a Drug Induced Sleep Endoscopy (DISE). Implantation and follow-up are performed at the CHUV with the collaboration between the SAOS-ronchopathie unit, the maxillofacial and dental surgery division and the center for investigation and research on sleep (CIRS). In this article, we present the technique, its indication and the outcomes through a recent review of the literature. This new device has been used for five years, mainly in the United States and Europe.
