What is a Voice Prosthesis Device?

 A voice prosthesis device is an artificial device which is used in voice therapy to help the laryngectomized individuals and is made up of silicon. Laryngectomy is a procedure in which the entire voice box (larynx) is removed and the trachea and oesophagus are separated from each other. During this operation, an opening is done between trachea and oesophagus and is called as a tracheo-oesophageal puncture.

Even though there are unique characteristics the voice prosthesis is quite consistent. At the end of the voice prosthesis, there are retaining flanges, tracheal flange, and oesophageal flange. They vary in size and rigidity. This device has a single-way valve which enables pulmonary air to pass into the oesophagus and pharynx to produce the sound and it helps to prevent the contents like saliva or liquids from the oesophagus, from entering the trachea.

The neoglottis is responsible for the favourable airflow characteristics and the voice prosthesis is responsible for the total resistance are expected to enable the patient to speak with less effort. The voice sounds rather clear but not very loud. The quality of voice is improved by airflow resistance of the voice prosthesis, pulmonary support and airflow resistance of the new source.
