Acceptance of a New Voice Prosthesis | 203 8 intervention, except for a replacement. The median device lifetime of the whole group was 64 days (mean 120 days, range 14-370). Upon exclusion of the VPs with periprosthetic leakage and the VPs that were brushed out, the median device lifetime was 101 days for this subgroup (mean 167, range 26-370). See figure 5. Figure 4. Overview of subjective and objective voice outcomes A: VHI10 scores, range 0-40. A score above 11 points (red line) is considered as having an abnormal voice, which is subjective limiting in daily life. B: AVQI scores, range 0-10. The lower the score, the better the voice. A score < 2.95 (red line) is considered as having a healthy voice. C: Voice quality as rated by SLPs, range 0-10. A score <5.5 is rated as poor/pathologic. D: Effort to speak as rated by SLPs, range 0-10. A score <5.5 is rated as too much. The trade-off question showed that the minimum desired device life of the PVHP, to outweigh disadvantages, was median six months (range three to twelve months). During the long-term study period there were no new adverse events reported.
