ABSTRACT:
An artificial larynx prosthesis (C) is object of the present invention, comprising: a first substantially ring-shaped element (A), taller in the back than in the front; a second pyramid-shaped element (B) placed, along its ridge, on the uppermost part of the first element, (A) so as to form what is substantially a single body. The prosthesis is a static crico-arytenoid unit that can be implanted in the forward region of the neck of a patient, who is subjected to total laryngectomy, between the patient's hypopharynx, trachea and esophagus.
