Airway resistances were calculated for two newly commercialized tracheoesophageal (TE) puncture prostheses: the PanjeTM Low Pressure Voice Button and the Blom-Singer® Low Pressure device. The airway resistances of newly commercialized PanjeTM Low Pressure devices could not be distinguished from those calculated for previously commercialized, Regular Pressure Voice Button devices. Airway resistances of Blom-Singer® Low Pressure devices increased systematically as a function of flow rate. Findings are compared with existing data to provide readers with an opportunity to evaluate the relative efficiency of air shunting among contemporary TE puncture prostheses. Results are interpreted in relation to their implications for selecting surgical-prosthetic options for laryngectomized patients.
