ABSTRACT:
A voice prosthesis formed as a small diametered, flexible walled, generally linear tube having an air valve at its inner end, a flexible retention collar intermediate its ends and a mounting tab at its outer end is adapted for insertion into a surgically placed tracheoespohageal fistula following laryngectomy for restoring the power of speech to the user. A larger diametered, relatively short, curved tracheal tube or cannula provided with a retention collar at its outer end is insertable into the tracheal stoma to prevent closure thereof; the cannula partially surrounding and guarding the mounted prosthesis which transects the tracheal cannula, by passing through an elongated channel opening, which is open at one end and extends along the outer wall of the tracheal tube. The arrangement of the two tubes is such that the larger tracheal cannula is readily inserted and withdrawn from the tracheal stoma without disturbing the mounted voice prosthesis.
