Hypoglossal nerve stimulation (HGNS) is a treatment which can help patients with obstructive sleep apnoea (OSA) breathe better while sleeping in comfort. This treatment involves implanting a small device in the neck and chest of the patient via a surgical procedure. The device monitors the patient's breathing during sleep, and delivers a mild electrical stimulation to move the tongue forward with each breath. This
prevents the tongue from blocking the back of the throat, keeping the patient's
upper airway open and maintaining smooth airflow. Compared to continuous positive airway
pressure (CPAP) therapy, the most commonly recommended treatment for OSA, patients
do not need to put on an external device which may cause discomfort and
inconvenience. You may also read this article to find out more.
