Prosthetic rehabilitation of voice after total laryngectomy has gained wide acceptance in the last 10 years. Several reliable voice prostheses have been developed and used successfully. Priorities for further development of the methods and instruments for prosthetic voice rehabilitation have led to the design of a low-resistance, self-retaining voice prosthesis (Provox) and an adapted replacement method. The results obtained in 79 patients are described. In vivo airflow resistance ranged from 1.0 to 3.8 kPa (mean = 1.9 kPa). Speech quality was good in 91% of the patients. The self-retaining properties of the prosthesis appeared to be satisfactory. The average device-life was more than 5 months. Replacement of the prosthesis with a new disposable guide wire was done quickly as an outpatient procedure. Maintenance of the prosthesis by the patient was simple. The new low-resistance, self-retaining Provox voice prosthesis and the modified replacement method appeared to further improve the results of prosthetic voice rehabilitation after total laryngectomy.
在过去10年中，全喉切除术后的语音假体康复已得到广泛认可。已经开发并成功使用了几种可靠的语音假体。进一步开发语音假体康复方法和器械的优先事项促使设计出一种低阻力、自固位语音假体（Provox）以及一种改良的更换方法。本文描述了79例患者所获得的结果。体内气流阻力范围为1.0至3.8千帕（平均 = 1.9千帕）。91%的患者语音质量良好。假体的自固位性能似乎令人满意。平均装置使用寿命超过5个月。作为门诊手术，使用新的一次性导丝快速更换假体。患者对假体的维护很简单。新型低阻力、自固位的Provox语音假体和改良的更换方法似乎进一步改善了全喉切除术后语音假体康复的效果。
