The oropharyngeal swallow mechanism is comprised of several behaviours that change systematically or occur randomly. The systematic changes are dependent on the bolus characteristics (i.e. volume and viscosity) and voluntary control. An oropharyngeal swallow is rapid (less than 2 s), and videofluoroscopy is required to determine which muscles or nerves are damaged in dysphagic patients. Once the specific problem has been identified, a treatment plan can be designed. Various categories of treatment are available, including behavioural procedures such as changes in head postures, heightening sensory input prior to the swallow, voluntary manoeuvres, exercise programmes, medications and surgical procedures. A swallowing specialist, usually a speech-language pathologist, identifies and assesses optimal treatments and works with the patient to improve swallowing patterns in order to return the patient to safe and efficient oral intake. This chapter describes these approaches.

口咽吞咽机制由几种系统变化或随机发生的行为组成。系统的变化取决于推注特性 (即体积和粘度) 和自愿控制。口咽吞咽迅速 (少于2 s),需要进行视频透视以确定吞咽困难患者的肌肉或神经受损。一旦确定了具体问题,就可以设计治疗方案。可以使用各种类型的治疗方法,包括行为程序,例如头部姿势的变化,吞咽前提高感觉输入,自愿演习,锻炼计划,药物和外科手术。吞咽专家 (通常是言语病理学家) 识别并评估最佳治疗方法,并与患者一起改善吞咽方式,以使患者恢复安全有效的口服摄入。本章介绍了这些方法。
