Voice button prosthesis

特許 権利維持 A voice prosthesis (plural prostheses) is an artificial device, usually made of silicone that is used to help laryngectomized patients to speak. During a total laryngectomy, the entire voice box (larynx) is removed and the windpipe (trachea) and food pipe (esophagus) are separated from each other. During this operation an opening between the food pipe and the windpipe can be created (primary puncture). This opening can also be created at a later time (secondary puncture). This opening is called a tracheo-esophageal puncture (TE puncture). The voice prosthesis is placed in this opening.
