ABSTRACT
OBJECTIVES/HYPOTHESIS: The majority of laryngectomy patients fail to use a hands-free valve on a daily basis, mainly due to fixation problems of the adhesive baseplate housing. To support adhesive housings during hands-free speech a new external neck brace (ENB 2.0) was developed. The effect of the brace was assessed in terms of a qualitative assessment, adhesive lifetime, maximum phonation time and patient self-reports. STUDY DESIGN: Twenty laryngectomees participated in this randomized, prospective, crossover trial. METHODS: All participants used the Provox hands-free HME valve with an Xtrabase adhesive for 1 month, 2 weeks with an ENB 2.0, and 2 weeks without. Outcomes were compared with the previous model of the external neck brace (ENB 1.0). RESULTS: The average total number of adhesive baseplates used during the trial was 16.7 in the non-brace group versus 10.9 in the brace group (P = 0.05). The number of daily replacements was 1.4 in the non-brace group and 1.1 in the brace group (P = 0.025). The average time a hands-free valve was worn per baseplate was 9.5 hours when wearing a neck brace versus 7.3 hours without brace (P = 0.09).The majority (81%) of the patients considered the neck brace 2.0 as a welcome addition to improve hands-free speech after laryngectomy and would use it if prescribed (88%). CONCLUSION: The new model of the neck brace reduces the number of baseplate replacements during hands-free speech and is considered as a helpful device by 81% of the participants.
