An experimental study was designed to explore the possibility of utilizing solely the dorsum of tongue to create a pseudoepiglottis. This was not possible in our particular experimental model. In combination with a "stabilizing and reinforcing" esophageal flap, an intact, functioning pseudoepiglottis was successfully achieved in six dogs, four of which were long-term survivals. This experiment was done primarily to determine the possibility of adding an important facet to the prevention aspiration in the ultimate goal of reconstructing the hypopharynx after total laryngectomy.
