Voice prosthesis

Speaking with a voice prosthesis is the most common method used today following total laryngectomy. It is also considered to be the most successful of the three methods for voice rehabilitation – creating the most natural sounding and fluent voice.

How it works

A voice prosthesis is a plastic device, usually made of medical grade silicone. It will be placed between the food pipe (your esophagus) and windpipe (your trachea) during the total laryngectomy, or in a secondary puncture.

The voice prosthesis has two flanges to keep it in place – one at the side of the food pipe and one at the side of the windpipe. Between these flanges there is a smaller tube which contains a one-way valve. This valve will open when speaking, and close while breathing and eating to prevent any foreign bodies entering your windpipe (e.g. saliva, food or drink).

By occluding your stoma, the exhaled air will be redirected through the voice prosthesis into your food pipe. As this air travels through your food pipe, the tissue will vibrate and create a sound. This is called tracheaesophageal speech (TE speech).

These days tracheaesophageal speech has proven to be the most successful method to be able to speak again after a total laryngectomy.
