Palatopharyngeal dysfunction may take place when palatopharyngeal valve is unable to perform its own closing due to a lack of tissue (palatopharyngeal insufficiency) or lack of proper movement (palatopharyngeal incompetence). Palatopharyngeal insufficiency induces nasal regurgitation of liquids, hypernasal speech, nasal escape, disarticulations and impaired speech intelligibility. Prosthetic management of palatopharyngeal insufficiency requires a close co-operation between an otolaryngologist and a speech pathologist. As a result, the patient can be socially and physically rehabilitated with the improved speech quality as well as prevention of leakage of liquids.
当腭咽瓣因组织缺乏（腭咽功能不全）或缺乏正常运动（腭咽闭合不全）而无法自行关闭时，可能会发生腭咽功能障碍。腭咽功能不全会导致液体经鼻腔反流、鼻音过重、鼻腔漏气、发音不清和言语清晰度受损。腭咽功能不全的修复治疗需要耳鼻喉科医生和言语病理学家密切合作。这样一来，患者就能在言语质量得到改善以及防止液体泄漏的情况下实现社交和身体康复。
