Endotracheal artificial larynx -- preliminary report.

Journal Article (Journal Article)

In experimental animals a one stage surgical procedure has been developed which at laryngectomy allows for the creation of a wide and patent tracheopharyngeal fistula. An endotracheal artificial larynx has been developed which has been found effective in prevention of aspiration in experimental animals. Bench studies indicate that an adequate voice probably can be obtained with this device.
