The concepts regarding velopharyngeal function, the production of disordered nasalization, and the management of velopharyngeal dysfunction can be summarized as follows: 1. Although the function of the velopharyngeal mechanism is critical to the control of oral-nasal balance, the configuration and function of the speech articulatory system as a whole will determine the degree of nasalized speech that is produced. 2. Velopharyngeal dysfunction can be related to one or a combination of structural and motor limitations within the velopharyngeal mechanism. 3. There are two perceptual manifestations of velopharyngeal dysfunction. One is acoustic (nasality); the other is aerodynamic (nasal emission). For any given speaker, it is possible to hear both, and it is possible to hear one and not the other. 4. Velopharyngeal dysfunction can be treated in a variety of ways. The method of treatment should be determined by the structural characteristics of the velopharyngeal mechanism and the speech-motor abilities of the patient.
关于腭咽功能、异常鼻音产生以及腭咽功能障碍的处理等概念可总结如下：1. 尽管腭咽机制的功能对于控制口鼻腔平衡至关重要，但整个言语发音系统的结构和功能将决定所产生的鼻音程度。2. 腭咽功能障碍可能与腭咽机制内的一种或多种结构及运动限制有关。3. 腭咽功能障碍有两种可察觉的表现形式。一种是声学方面的（鼻音）；另一种是空气动力学方面的（鼻漏气）。对于任何给定的说话者，有可能同时听到这两种表现，也有可能只听到其中一种而听不到另一种。4. 腭咽功能障碍可用多种方法进行治疗。治疗方法应根据腭咽机制的结构特征和患者的言语运动能力来确定。
