NCT00743262

Brief Summary

The purpose of this study is to investigate the performance of a new voice prosthesis in comparison with the Provox2 and the Provox ActiValve voice prosthesis in 15 laryngectomized patients. Factors taken into account are clinician and patient satisfaction with the insertion system, patient satisfaction with voice, speech, performance, and maintenance. Voice and speech will also be evaluated for the different prostheses by means of perceptual evaluations and acoustic analysis.

Outcome Measures

Primary Outcomes (1)

  • Short-term Feasibility Provox Vega 22.5 French

Limitations and Caveats

Provox ActiValve users have short device life with normal indwelling prostheses (and hence use the Provox ActiValve). Therefore, the device life measured in this patient group is very short and not representative of the normal Provox Vega user.
