Abstract：
Background: this prospective study investigated the correlation between the oral bacterial microflora and the microflora found in voice prostheses (VPs) among 20 patients who had undergone laryngectomy. The aim was to explore the associations between the microflora\'s presence and the malfunction of VPs, along with the association between the predominant microorganism and the longevity of VPs. Methods: the research process included gathering medical histories, conducting ENT examinations, replacing VPs, and performing check-ups every four months for a period of 15.5 months. Additionally, microbiological examinations, blood tests, and voice change surveys were conducted. Results: a correlation between the microflora isolated from VPs and that from oral rinses was demonstrated in a large percentage of patients who experienced a loss of prosthetic functional efficiency. The correlation analysis between the type of microorganism and the lifespan of VPs showed a non-significant Pearson correlation coefficient (r = 0.043, p = 0.678). Conclusions: there is no significant linear correlation between the predominant microorganism and the average lifespan of VPs.
摘要：
背景：这项前瞻性研究调查了20例接受喉切除术的患者的口腔细菌菌群与语音假体（VP）中发现的菌群之间的相关性。目的是探索微生物群的存在与VPs故障之间的关联，以及优势微生物与VPs寿命之间的联系。方法：研究过程包括收集病史，进行耳鼻喉科检查，替换VPs,每四个月进行一次检查，为期15.5个月。此外,微生物检验,验血,并进行了语音变化调查。结果：在很大一部分经历假体功能效率丧失的患者中，证明了从VP中分离出的微生物区系与从口腔冲洗中分离出的微生物区系之间的相关性。微生物类型与VPs寿命的相关性分析显示，Pearson相关系数不显著（r=0.043，p=0.678）。结论：优势微生物与VPs的平均寿命之间没有显着的线性相关性。
