“…The most common reason for replacement of an indwelling device is leakage through the device. Other reasons for replacement are for example the need for size changes, increased speaking effort, granulation tissue and inflammation/infection (‘device-related’ reasons) [ 12 , 22 ]. Reasons for diversity in device life duration such as patient- and treatment characteristics as well as socioeconomic and reimbursement aspects are also focus of research [ 19 ].…”

The aim of the study was to compare device life of more recent indwelling voice prostheses Provox Vega and Blom-Singer Dual Valve to device life of well-known standard devices (Provox 2, Blom-Singer Classic). In a prospective, non-randomised study, device life of Blom-Singer Classic, Blom-Singer Dual Valve, Provox2, Provox Vega and Provox ActiValve voice prostheses was recorded in a group of 102 laryngectomised patients. In total 749 voice prosthesis were included. Average overall life time was 108 days, median 74 days. The prosthesis with the longest dwell time was the Provox ActiValve (median 291 days). Provox Vega had longer device life compared with Provox2 (median 92 days vs 66 days; p = 0.006) and compared with Blom-Singer Classic (median 92 days vs 69 days; p = 0.004). In conclusion, device lifetimes of Provox Vega and ActiValve were better than those of Provox2 and the Blom-Singer Classic. New voice prostheses, with a defined valve opening pressure (Provox Vega, Provox ActiValve, Blom-Singer Dual Valve) had longer lifetimes than prostheses without a defined opening pressure (Blom-Singer Classic and Provox 2).

“…dietary patterns, use of antifungal treatment, cleaning, controlled supraesophageal reflux), treatment characteristics (e.g. prior radiotherapy, follow-up support), as well as socioeconomic and reimbursement factors [11–13, 17, 20–23]. Another potential factor is device design.…”

Device life of the Provox Vega Indwelling voice prosthesis is as yet untested outside Europe. The current study examined device life and reasons for replacement within an Australian clinical setting. Twenty-three participants were monitored for device life and reasons for replacement. Main outcome measure was days to failure of initial device. Average device life and reasons for replacement were secondary measures. Initial device life data revealed 67 % had functioning devices at 3 months, 52 % at 6 months and 29 % at 12 months. Average device life was 207 days (median of 222). The majority of devices (97 %) failed due to leakage through the prosthesis. The Provox Vega Indwelling voice prosthesis had favourable device life in this cohort of patients and in comparison to European data. Reasons for replacement were consistent with international literature.
