Laryngeal reinnervation

Laryngeal reinnervation

Normally, the brain sends signals to the laryngeal muscles which control the movement of vocal cords, which open to allow air to pass, or close and vibrate to create sound waves and speech.

Surgery and accidents take the voices of thousands of people every year. When one or both of the recurrent laryngeal nerves are severed, injured or diseased, control of the voice may be lost.

In laryngeal reinnervation, a nerve from another part of the body, such as the strap muscle of the neck, is grafted around the affected nerve to restore the natural voice.
