Myofunctional therapy is a set of tongue and throat exercises that aims to increase the tone and strength of your tongue and throat muscles. We recommend it for patients with obstructive sleep apnoea (OSA) as the muscles in their throat and tongue are more relaxed during sleep, resulting in a collapse of their airway. MFT exercises can help to increase the tone and strength of these upper airway muscles, thereby reducing the collapse of the upper airway during sleep.
