Airway resistance of the voice button.
Airway resistance calculations were completed for Voice Button prostheses. Resistance of these devices ranged from about 285 to 440 cm H2O/L/s, revealing that the opposition these prostheses offer to airflow through them is substantial. In this circumstance, a reduction inthe efficiency with which tracheoesophageal voice is produced would be expected.
