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.
Twenty laryngectomees participated in this randomized, prospective, crossover trial.
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).
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%).
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.
目的/假设:大多数喉切除术患者无法每天使用免提阀,主要是由于粘合底座外壳的固定问题。为了在免提语音期间支撑粘合外壳,开发了一种新的外部颈部支撑(ENB 2.0)。通过定性评估、粘合寿命、最大发音时间和患者自我报告来评估支撑的效果。
20 名喉切除术患者参与了这项随机、前瞻性、交叉试验。
所有参与者都使用 Provox 免提 HME 阀和 Xtrabase 粘合剂使用 1 个月,使用 ENB 2.0 2 周,不使用 2 周。结果与之前的外部颈部支撑(ENB 1.0)模型进行了比较。
试验期间,非支撑组平均使用粘合基底板总数为 16.7 个,支撑组为 10.9 个(P=0.05)。非支撑组每天更换的次数为 1.4 次,支撑组为 1.1 次(P=0.025)。佩戴颈部支撑器时,免提阀每个基底板的平均佩戴时间为 9.5 小时,不佩戴支撑器时为 7.3 小时(P=0.09)。大多数(81%)患者认为颈部支撑器 2.0 是改善喉切除后免提语音的有用附加装置,如果开处方,他们会使用(88%)。
新型颈部支撑器可减少免提语音期间基底板更换的次数,81%的参与者认为它是一种有用的设备。
