Abstract

Background: Voice restoration with a voice prosthesis has recently become popular among laryngectomized patients due to good voice quality and functional outcomes. An important limitation, however, is the need to periodically replace these devices. Factors affecting prosthesis lifespan differ between countries and regions. We assessed determinants of replacement frequency in Japan.

Methods: This retrospective, observational study included 45 patients who opted to receive a voice prosthesis after total laryngectomy. Twenty-one patients were excluded, and thus 24 were analyzed. We defined 3 types of factors affecting voice prosthesis replacement: tracheal site factors, esophageal site factors, and types of prostheses. The association of each factor with device lifespan was examined using the Mann-Whitney U test and Kruskal-Wallis test.

Results: Twenty-four patients consented to this study and were surveyed about device lifespan. Twenty-one male patients and three female patients underwent voice prosthesis insertion for secondary voice restoration after total laryngectomy. The mean duration before replacement was 85 ± 36 (range 14-434) days. Total follow-up duration and tracheal dryness were both significantly associated with device lifespan.

Conclusion: Learning to properly manage the VP over time and preventing tracheal dryness are required to prolong voice prosthesis lifespan in Japan.

影响喉切除术患者假声装置使用寿命的因素。

背景：由于良好的语音质量和功能效果，在喉切除术患者中使用假体进行语音修复已成为一种流行的方法。然而，一个重要的限制是需要定期更换这些设备。影响假肢寿命的因素因国家和地区而异。我们评估了日本更换频率的决定因素。方法：本回顾性观察性研究包括45例在全喉切除术后选择接受假声的患者。排除21例，共分析24例。我们定义了3种影响假体置换术的因素：气管部位因素、食管部位因素和假体类型。使用Mann-Whitney U检验和Kruskal-Wallis检验检验每个因素与设备寿命的关系。结果：24名患者同意这项研究，并对设备寿命进行了调查。21例男性患者和3例女性患者在全喉切除术后接受了人工植入术进行二次语音修复。更换前的平均持续时间为85±36（范围14-434）天。总随访时间和气管干燥度均与器械使用寿命显著相关。结论：在日本，要延长假声假体的使用寿命，必须学会正确管理假声，防止气管干燥。

期刊介绍： Yonago Acta Medica (YAM) is an electronic journal specializing in medical sciences, published by Tottori University Medical Press, 86 Nishi-cho, Yonago 683-8503, Japan. The subject areas cover the following: molecular/cell biology; biochemistry; basic medicine; clinical medicine; veterinary medicine; clinical nutrition and food sciences; medical engineering; nursing sciences; laboratory medicine; clinical psychology; medical education. Basically, contributors are limited to members of Tottori University and Tottori University Hospital. Researchers outside the above-mentioned university community may also submit papers on the recommendation of a professor, an associate professor, or a junior associate professor at this university community. Articles are classified into four categories: review articles, original articles, patient reports, and short communications.
