Observations of prepharyngeal and postpharyngeal flap degrees of lateral pharyngeal wall movement seem to indicate that some individuals have the ability to alter patterns of lateral pharyngeal wall motion. However, most of the subjects did not show changes in lateral pharyngeal wall motion, and in those who did show changes, the effects of speech therapy could not be excluded. Therefore, the suggestion that pharyngeal flaps should be "tailored" to the size of the gap in the velopharyngeal sphincter seems valid. Or, to put it differently, it seems likely that in many individuals, if the pharyngeal flap constructed is not as broad as the velopharyngeal gap, velopharyngeal insufficiency and hypernasality are likely to persist because most often the lateral pharyngeal wall movement will not adapt to the presence of a new structure in the pharynx.
对咽前和咽后瓣水平咽侧壁运动程度的观察似乎表明，一些个体有能力改变咽侧壁运动模式。然而，大多数受试者并未表现出咽侧壁运动的变化，而在那些确实出现变化的受试者中，言语治疗的影响无法排除。因此，关于咽瓣应根据腭咽括约肌间隙大小进行“定制”的建议似乎是合理的。或者，换一种说法，在许多个体中，如果所构建的咽瓣不如腭咽间隙宽，腭咽功能不全和高鼻音可能会持续存在，因为大多数情况下，咽侧壁运动不会适应咽部新结构的存在。
