Swallowing disorder, which can be simply understood as difficulty in eating, is very unfamiliar to most people, but it is a common dysfunction in the daily treatment work of the rehabilitation department, mostly seen in various neurological diseases and craniofacial tumors, etc. It can cause patients to suffer from dehydration, malnutrition, aspiration, recurrent aspiration pneumonia, and even suffocation in the process of eating in some patients, which can endanger their lives. Therefore, it is especially important to diagnose and evaluate patients’ dysphagia early and timely, to carry out reasonable and scientific rehabilitation treatment, to reduce complications, and to improve patients’ own feeding function. 1. What is a normal swallowing process like? Normal swallowing is a smooth and dynamic continuous process that is accomplished by the coordinated action of relevant muscles and joints and nerves. It first requires chewing food to form an effective food mass, then through the back of the tongue, the food mass is transported to the pharynx, which initiates our swallowing reflex, the larynx closes to close the trachea, and the food mass passes through the esophagus into the stomach. These complex movements constitute the swallowing activities that we normal people perform every day. 2.What diseases can cause swallowing difficulties? (1) Stroke, traumatic brain injury; (2) Head and neck tumors: such as after surgery for oral cancer, oropharyngeal cancer and tongue cancer, after total laryngectomy, after partial laryngectomy, after anastomotic stenosis after esophageal cancer surgery, after radiotherapy for nasopharyngeal cancer, etc.; (3) Cerebral palsy, Parkinson’s disease, multiple sclerosis, etc.; (4) Elderly people, long-term bedridden people. 3.How to treat swallowing disorder? For patients who may have swallowing difficulties, they need to be evaluated early for swallowing function and receive individualized and targeted rehabilitation treatment to reduce choking and misaspiration and avoid serious complications. Due to the complex etiology of patients with dysphagia, there is a wide variation in treatment approaches. (1) Vocal cord laryngeal massage: massage the vocal cords of the larynx from left to right and lift the hyoid bone with slight force; (2) Ice stimulation: stimulate the tongue, palatal arch and posterior pharyngeal wall with ice swabs; (3) Mouth and face movement training: let the patient do lip pursing, lip gathering, cheek puffing, lip smacking and tooth showing; (4) Tongue function training: let the patient stick out the tongue forward, backward, left and right, and you can add some resistance with tongue depressor; (5) Breathing training (5) Breathing training: blowing whistle, blowing candle, blowing respirator; (6) Swallowing posture change: the patient can be asked to swallow with low head, tilted head, or turned head; (7) Swallowing electrical stimulation: subglottis and facial electrical stimulation is performed to stimulate the recovery of muscle function, while breath-hold swallowing is performed.
