[Trocar for forming an esophagotracheal fistula in secondary implantation of a voice prosthesis].
In patients after laryngectomy it is sometimes difficult to form an esophagotracheal shunt for secondary implantation of an artificial larynx. We have developed a special trocar for this purpose. This new instrument allows the surgeon to form an esophagotracheal shunt in varying anatomic pharynx funnels. A special modified point helps avoid granulation and stenoses surrounding the fistula.
