This study involved audiologic and otologic evaluations of 77 subjects with VPI not due to overt cleft palate, aged 4-16 years. Audiological findings revealed that: 49 per cent had a hearing loss (74 per cent conductive, 16 per cent sensori neural, 10 per cent mixed) and that 18 per cent of the subjects had inconsistent audiologic findings. Otologic evaluations revealed that 44 per cent had abnormalities of the tympanic membrane. It can be concluded that the VPI subjects differed appreciably from the normal and more closely resembled a cleft palate population.
本研究对77名年龄在4至16岁、非明显腭裂导致的腭咽闭合不全患者进行了听力学和耳科学评估。听力学检查结果显示：49%的患者有听力损失（74%为传导性听力损失，16%为感音神经性听力损失，10%为混合性听力损失），18%的患者听力学检查结果不一致。耳科学评估显示，44%的患者鼓膜有异常。可以得出结论，腭咽闭合不全患者与正常人群有明显差异，更类似于腭裂人群。
