Tongue cancer has a high incidence, fast development and lymph node metastasis easily in the late stage of development, so patients often have a poor prognosis, while early detection and treatment are more ideal. Surgery or surgery combined with radiotherapy is the main means of tongue cancer treatment, but in the process of surgery, dysphagia is a common complication after surgery due to the special nature of the surgical site and the change of oral structure. Dysphagia can also be secondary to lung infection and malnutrition, leading to the decrease of life quality. Therefore, the recovery of swallowing function is indispensable to the postoperative rehabilitation of cancer patients. Generally, patients are instructed to practice swallowing as soon as 2 weeks after surgery, and there are generally electrical stimulation, direct dysphagia treatment and compensatory training. So what should we do to improve swallowing ability in general? Cold stimulation of the soft palate, tongue root and posterior wall with an ice stick, followed by empty mouth swallowing action, 3-5 times a day for 5 minutes each time. With the head of the bed elevated at 45° in a semi-sitting position, use a spoon to deliver food into the deep part of the mouth, and the patient’s head is tilted back to deliver food to the pharynx to avoid food leakage. The amount of food should be small and slow at each feeding to avoid choking. So, how to train the tongue body function on the basis of gradual recovery? Food can be placed on the healthy side of the tongue and slowly stirred with the residual tongue body to exercise the swallowing action in steps. First use the tongue to deliver the food to the pharynx, then swallow slowly into the esophagus. Food should be gradually transitioned from liquid to regular food, avoiding dry and hard food. To reduce choking and coughing, it should be done in small amount and slowly to gradually form a habit. For patients with tongue root cancer, the start of chewing training can be delayed to avoid tongue root incision pulling and infection. Chewing function training is also very important. Usually, you should choose fine, soft, not easy to loose and easy to chew food, such as tofu, banana, meat cake, lotus root powder, etc. Avoid foods such as dried salt fish, fibrous potatoes, onions, etc. Avoid overheated food and gradually adapt to residual and skin flap tongue tissue activities, and train the amount of food from little to much, 3 to 5 times a day, and gradually increase the number of times until the chewing function is fully recovered. The usual massage of the tongue body is also very important and requires active cooperation from the family. 1, use the thumb to massage the tongue body from the inside out in a circular motion, with the strength of the normal tongue body to feel the pain of touch pressure is moderate, so that the scar softens, 8-10 times a day, 10 minutes each time. 2, 2 weeks after the removal of the graft suture and incision healing, i.e. 1 month after surgery, let the patient do the training of tongue forward extension, upward, lateral extension and downward resistance, 3-5 times a day, 5-10 minutes each time. 3, often talk with the patient to increase the tongue body activity, as soon as possible to restore function. If you cannot extend the tongue on your own, use a clean tissue or cloth to gently hold the tongue and perform upward and downward movements. Note: When massaging the tongue body of softened flap, the action should not be rough to avoid obstruction of blood supply to the flap; when chewing and swallowing training, especially for patients with cancerous tongue root, the position of flap tissue is deep, chewing should avoid food with many fibers and swallowing should not be too early to avoid excessive stretching of the trauma and infection.
