Children with dysarthria are often seriously handicapped by their inability to communicate. Velopharyngeal incompetence may contribute to their speech difficulties but the indications for pharyngoplasty are poorly defined. The speech of 41 children, thought to have a defect of neurological origin and referred for possible pharyngoplasty, was assessed by a speech therapist, by nasopharyngoscopy and by multiview videofluoroscopy. These investigations revealed that 16 had velopharyngeal incompetence, with a neurological aetiology, and might be expected to benefit from pharyngoplasty. Independent assessment of the intelligibility of these 16 children before and after pharyngoplasty has been related to their preoperative oropharyngeal function. The majority benefited from surgery, some substantially. In particular, good lip and tongue function are shown to be necessary to achieve improved intelligibility. The roles of age, intelligence and aetiology in the success of pharyngoplasty are discussed.
构音障碍儿童常常因无法交流而严重致残。腭咽功能不全可能导致他们的言语困难，但咽成形术的适应症尚不明确。41名被认为有神经源性缺陷并被转诊以考虑进行咽成形术的儿童，其言语由言语治疗师、鼻咽镜检查和多视角电视荧光镜检查进行评估。这些检查发现，16名儿童存在神经病因导致的腭咽功能不全，可能会从咽成形术中获益。对这16名儿童咽成形术前后可懂度的独立评估与他们术前的口咽功能有关。大多数儿童从手术中获益，有些获益显著。特别是，良好的唇和舌功能被证明是提高可懂度所必需的。本文还讨论了年龄、智力和病因在咽成形术成功中的作用。
