Acceptance of a New Voice Prosthesis | 205 8 Figure 5. Kaplan Meier curve of the Device lifetime of the PVHP A: The whole group (n=15), B: Without periprosthetic leakage and lost VPs (n=9) Acceptance after ending study Two participants did not accept the PVHP due to early leakage. Of the remaining thirteen participants who continued in the long-term phase, six participants accepted the PVHP but one of them preferred the ActiValve Light because of the experienced longer device lifetime. The remaining seven did not accept the PVHP because of the relatively short device lifetime. In total six out of fifteen participants (40%) accepted the PVHP after ending the study (see table 2 and figure 6). Figure 6. Overview of acceptance of the PVHP at two time points
