ABSTRACT:
A method of placing an esophageal voice prosthesis in a patient who has undergone a laryngectomy to be performed by a surgeon to permit the patient to restore speech patterns. The method comprises the steps of sedating the patient under local anesthesia, introducing a flexible endoscope into the patient's mouth so that it reaches the patient's esophagus, introducing a Seldinger needle into the patient to puncture the tracheostoma and enter the esophagus and create a passageway therethrough. The surgeon measures the tracheostoma length to determine the proper sized prosthesis to use by threading a measuring catheter and length of gastrostomy tubing about a guide wire to the prosthesis implantment site. The measuring catheter is removed with the guide wire in place, and a voice prosthesis is attached to the gastronomy tubing and threaded over the guide wire so that the prosthesis is in place at the implantment site. The gastronomy tubing is then removed and the prosthesis is ready for use.
