Velopharyngeal insufficiency was assessed using multiview videofluoroscopy on eight patients with hypernasality, 10 patients with hypernasality and audible nasal emission, and 10 patients with nasal turbulence (rustle). Patients demonstrating hypernasality, with or without audible nasal emission, were found to have a significantly larger velopharyngeal gap than those with nasal rustle. This finding suggests that the degree of the velopharyngeal insufficiency can be predicted to some extent based on perceptual assessment. If the presence of a nasal rustle suggests a small velopharyngeal gap, despite the severe distortion of speech, then speech therapy should be considered prior to surgery in those cases.
对8名鼻音过重患者、10名鼻音过重且伴有可闻鼻漏气的患者以及10名有鼻湍流（沙沙声）的患者，使用多视角电视荧光透视法评估腭咽闭合不全情况。发现有鼻音过重的患者，无论有无可闻鼻漏气，其腭咽间隙都比有鼻沙沙声的患者明显更大。这一发现表明，腭咽闭合不全的程度在一定程度上可以根据感知评估来预测。如果存在鼻沙沙声表明腭咽间隙较小，尽管语音严重失真，那么在这些情况下，手术前应考虑进行言语治疗。
