The Artificial Larynx
• An individual who has had a laryngectomy
is a likely candidate for an artificial larynx,
also called an electrolarynx.
What is a laryngectomy?
• Laryngectomy: Surgery to remove part or all of
the larynx is a partial or total laryngectomy. In
either operation, the surgeon performs a
tracheostomy, creating an opening called a stoma
in the front of the neck (may be temporary or
permanent). Air enters and leaves the trachea and
lungs through this opening. A tracheostomy tube,
also called a trache tube, keeps the new airway
• A partial laryngectomy preserves the voice.
The surgeon removes only part of the voice
box, just one vocal cord, part of a cord, or
just the epiglottis, and the stoma is
temporary. After a brief recovery period ,
the trache tube is removed, and the stoma
closes up. The patient can then breathe and

however, the voice may be hoarse or weak.
• In a total laryngectomy, the whole voice
box is removed, and the stoma is
permanent. The patient called a
laryngectomee, breathes through the stoma.
A laryngectomee must learn to talk in a new
• There are several such devices on the market-of
basically two types. They are all battery powered,
but with one type of unit, you place it against your
throat, push a button, and the machine transmits a
vibration noise to your throat which you then form
into words and sounds with your lips, teeth, and
tongue. With the second type, the vibration sound
is transmitted directly into your mouth via a small
tube- words and sounds are made in a similar
