Velopharyngeal insufficiency (VPI) is a disorder in which air leaks out through the nose, reducing performance quality and capacity in wind and brass players. There have been limited studies on the prevalence of this potentially career-threatening disorder.
To identify the prevalence of VPI in a sample of conservatorium level woodwind and brass student instrumentalists in Australia.
Wind and brass students from four music institutions were recruited by email invitation to complete an online survey. Results from 77 musicians were analysed for their knowledge and experience of VPI. Musicians who had experienced VPI provided information on the characteristics, symptoms and treatment or advice sought for the disorder.
Of the 77 musicians included in the analysis, 44% had heard of VPI, 30% were aware of other musicians who had experienced VPI and 39% had personally experienced VPI.
The results suggest that VPI may be a common occurrence in wind and brass players. Informal discussions with colleagues and music teachers also suggest that VPI is a frequent phenomenon. This group of musicians represents the largest sample surveyed about VPI to date.
咽腔功能不全（VPI）是一种空气从鼻腔漏出的疾病，会降低管乐器和铜管乐器演奏者的演奏质量和能力。目前针对这种可能威胁职业生涯的疾病的研究还很有限。
在澳大利亚音乐学院水平的木管乐器和铜管乐器学生演奏家中确定咽腔功能不全的患病率。
通过电子邮件邀请，从四所音乐机构招募管乐器和铜管乐器学生参加在线调查。对 77 名音乐家的知识和咽腔功能不全经验进行了分析。曾经历过咽腔功能不全的音乐家提供了有关该疾病的特征、症状以及治疗或寻求建议的信息。
在纳入分析的 77 名音乐家，44%听说过咽腔功能不全，30%知道其他有过咽腔功能不全经历的音乐家，39%曾亲自经历过咽腔功能不全。
研究结果表明，咽腔功能不全可能在管乐器和铜管乐器演奏者中很常见。与同事和音乐老师的非正式讨论也表明，咽腔功能不全是一种常见现象。这组音乐家是目前调查咽腔功能不全的最大样本。
