Substantial differences have been established among in-vitro airway resistance properties of tracheoesophageal (TE) puncture prostheses (Weinberg & Moon, 1984). In this report, the impact of these in-vitro differences on the actual, in-vivo process of TE voice production is made explicit. Variation in in-vitro airway resistance among TE puncture prostheses is shown to exert substantial effects upon in-vivo phonatory mechanism opposition to flow, aerodynamic power required to initiate and sustain TE voice production, and TE phonatory efficiency. Individuals responsible for defining TE puncture options for laryngectomized patients are encouraged to consider these effects in clinical practice.
气管食管（TE）穿刺假体的体外气道阻力特性之间已确定存在显著差异（温伯格和穆恩，1984年）。在本报告中，这些体外差异对TE发声的实际体内过程的影响得到了明确阐述。结果表明，TE穿刺假体之间的体外气道阻力变化对体内发声机制的气流阻力、启动和维持TE发声所需的气动功率以及TE发声效率有重大影响。鼓励负责为喉切除患者确定TE穿刺方案的人员在临床实践中考虑这些影响。
