In Vivo Aerodynamic Characteristics of the Nijdam Voice Prosthesis [PDF]
Acta Oto-Laryngologica, 1997 The Nijdam voice prosthesis is an indwelling valveless voice prosthesis for postlaryngectomy voice rehabilitation. The in vitro aerodynamic characteristics are reported to be comparable to that of the low-resistance Groningen voice prosthesis. Owing to the design of the prosthesis the airflow resistance depends on the shaft length of the voice ...
