[Valve-neoglottis after laryngectomy by cartilage implantation into the trachea (author's transl)].

After laryngectomy the opening of the upper trachea is closed up to 3/4--4/5 by implantation of a cartilage plate (if possible from the epiglottis). The anterior part is left open. During exspiration the oesophago-pharyngeal flap is pressed upwards, whereas the position of the cartilage plate does not change much. The air can be expired by a 90 degrees turned 6--8 mm fistula (Staffieri) in the flap opposite of the cartilage plate (valve opened). As well as by its own weight as by flow of saliva, eating, drinking and vomiting the fistula is pressed on the cartilage plate (valve closed). By aid of this valve mechanism the patient can drink 1 week postoperatively without suffering from flow of saliva into the trachea. The patient's ability to speak developes well 10--14 days postoperatively.
