An artificial larynx of the pneumatic type is presented with preliminary data from dog experimentation. A controlled communication can be made between the trachea and esophagus utilizing this apparatus. The device is well tolerated when placed below the level of cricopharyngeus muscle in the dog. An esophageal valve functions well to prevent aspiration. Air flow through the apparatus is sufficient so that utilization in the human laryngectomy patient may be feasible.
