The performance of the ULR Groningen prosthesis was assessed in 21 laryngectomees. The intratracheal phonatory pressures (PITP), voice parameters (speech rate, maximal phonation time, maximal vocal intensity, dynamic vocal intensity range), device lifetime and patient's subjective acceptances were recorded and compared to identical parameters for other prostheses reported in the literature and to data obtained from an age-matched group of normal laryngeal speakers. The low airflow resistance of the ULR Groningen voice prosthesis objectively (PITP = 2.7 kPa) and subjectively leads to a low effort to phonate. Compared to "normals" maximal phonation time shows no significant difference, but speech rate, maximal vocal intensity and dynamic vocal intensity range show a significant worse outcome. The mean device lifetime of the ULR Groningen prosthesis is more than 13.6 weeks, which is comparable to other indwelling voice prostheses. In conclusion, the ULR Groningen voice prothesis enables easier tracheoesophageal phonation than the low-resistance Groningen type.
对21例喉切除患者的格罗宁根ULR假体性能进行了评估。记录了气管内发声压力（PITP）、嗓音参数（语速、最大发声时间、最大发声强度、动态发声强度范围）、装置使用寿命和患者主观接受度，并与文献中报道的其他假体的相同参数以及从年龄匹配的正常喉发声者组获得的数据进行比较。格罗宁根ULR语音假体的低气流阻力在客观上（PITP = 2.7 kPa）和主观上导致发声时用力较小。与“正常人”相比，最大发声时间无显著差异，但语速、最大发声强度和动态发声强度范围的结果明显较差。格罗宁根ULR假体的平均装置使用寿命超过13.6周，这与其他留置式语音假体相当。总之，与低阻力格罗宁根型相比，格罗宁根ULR语音假体使气管食管发声更容易。
