From January 2000 to December 2008, we conducted voice rehabilitation using the Provox2 voice prosthesis total-laryngectomy subjects. Of these, 36 attained restoration of 90.0%. Mean maximum phonation time (MPT) was 14.5s, ranging from MPT was not influenced by age, radiotherapy use, primary tumor site, or reconstructive surgery use. Voice prosthesis replacement averaged 25 weeks (5.8 months), ranging from 9 to 74 weeks. Complications occurred in 16 caces (40.0%), mainly granulation tissue formation and prosthesis-site infection, also aspiration pneumonia, prosthesis-site salivary leakage, inability to replace the prosthesis, tracheomalacia, bodies in the trachea. Management rather than medical problems included cost, frequent hospital visits, and lack of motivation to use a prosthesis. The Provox2 voice prosthesis speech provides a higher rate of speech restoration, longer phonatory better intelligibility. Management problems, however, require that we work to understand subjects' living environments and family situations better for evaluating Provox2 voice prosthesis indication more effectively.
2000年1月至2008年12月，我们对全喉切除术患者使用Provox2语音假体进行了嗓音康复治疗。其中，36例患者实现了90.0%的恢复率。平均最大发声时间（MPT）为14.5秒，范围为……MPT不受年龄、放疗使用情况、原发肿瘤部位或重建手术使用情况的影响。语音假体更换平均为25周（5.8个月），范围为9至74周。16例（40.0%）出现并发症，主要是肉芽组织形成和假体部位感染，还有吸入性肺炎、假体部位唾液漏、无法更换假体、气管软化、气管内异物。管理方面而非医疗问题包括费用、频繁就医以及使用假体的积极性不足。Provox2语音假体的语音恢复率更高，发声时间更长，清晰度更好。然而，管理问题要求我们努力更好地了解患者的生活环境和家庭情况，以便更有效地评估Provox2语音假体的适应证。
