One hundred Provox voice prostheses consecutively inserted in 37 patients and replaced only when phonation was impaired or complications noted were analyzed for in situ lifetime, causes for replacement, and complications. The mean in situ lifetime was 311 days. Actuarial analysis (Kaplan-Meier method) of the in situ lifetime revealed that 65.9%, 23.7%, and 16.4% of the voice prosthesis were still in situ by the 6th, 12th, and 18th postinsertion month. Cause for replacement was salivary leakage through the prosthesis valve, salivary leakage around the prosthesis, deterioration of the prosthesis, and excessive crusting resulting in increased airflow resistance in 33%, 27%, 24%, and 16% of cases, respectively. Complications included granulation tissue formation, cervical cellulitis, necrosis of the tracheoesophageal puncture, tracheostomal stenosis, and swallowing impairment in six, two, one, three, and one patient, respectively.
对连续植入37例患者体内的100个Provox语音假体进行分析，这些假体仅在发声功能受损或出现并发症时才进行更换，分析内容包括在位使用寿命、更换原因及并发症情况。在位平均使用寿命为311天。对在位使用寿命进行精算分析（Kaplan-Meier法）显示，在植入后的第6、12和18个月，分别有65.9%、23.7%和16.4%的语音假体仍在位。更换原因分别为唾液通过假体瓣膜漏出、假体周围唾液漏出、假体损坏以及结痂过多导致气流阻力增加，各占病例的33%、27%、24%和16%。并发症包括分别有6例、2例、1例、3例和1例患者出现肉芽组织形成、颈部蜂窝织炎、气管食管穿刺处坏死、气管造口狭窄和吞咽障碍。
