Tongue cancer is one of the common malignant tumors of the oral and maxillofacial region, which seriously threatens the life and health of people. At present, free tissue flap (such as anterolateral femoral flap) is often used to repair the defective area while radical tongue cancer surgery is performed; however, because of the conformability of the flap and the presence of atrophy, the later repaired tongue may have limited movement, which affects the functions of chewing, swallowing and pronunciation. The tongue is a functional organ and has a great influence on the patient’s functions such as pronunciation, swallowing and chewing. Patients often have a pessimistic psychology after learning that they have a tumor, especially because they are reluctant to communicate after surgery and are often emotionally depressed. For these psychological states of patients, family members should actively give psychological guidance, guide patients to face the reality frankly, adjust their mentality, adapt to the change of post-operative lifestyle and establish confidence to overcome the disease. Therefore, tongue function rehabilitation training is also an important guarantee for postoperative quality of life of tongue cancer patients, but it also requires family members to continuously encourage and guide patients in the training step by step, persevere and build up confidence. Functional training after tongue cancer surgery is mainly to increase the mobility and flexibility of the tongue, to make the tongue stretch forward and left and right, and to play the role of extension, which can generally be carried out after the wound healing. In the early postoperative period of tongue cancer, it is generally necessary to appropriately restrict tongue movement to prevent secondary infection and bleeding due to poor healing of the incision. When patients gradually recover, if they still cannot extend the tongue by themselves, sterile gauze can be used to wrap the tongue, gently hold the patient’s tongue for up and down and left and right movements, then put the tongue back to its original place, and finally gently hold the lower jaw to assist in closing the mouth. If the patient can practice by himself, the number of times can be gradually increased from 3 times a day for 5 minutes to 4 times a day for 10 minutes each time. What else should patients pay attention to in order to promote recovery after tongue cancer surgery? 1.Rinsing mouth: Besides rinsing mouth in the morning and after meals, patients should often use warm water to suck and drum cheeks to let the liquid impact back and forth in the mouth to remove food residues between teeth and moisten the mouth. 2, often drink water: often make swallowing action. This can not only stimulate saliva secretion, moisten the throat to quench thirst, and can exercise the tongue and cheek muscles. 3.Knock: upper and lower teeth gently knock 3 times for 7 days, and finally lick the tongue around the teeth for 1 week to end. 4.Neck activity: alternately turn the neck to the left and to the right, the angle must reach 45°, and carry out forward bending and backward stretching, put turning and other movements, once a day, each time about four eight beats. 5. Shoulder lift: Sit backwards in a reclining chair and lift the left and right shoulder alternately to move the shoulder joint once a day for 10 minutes. Note that if the patient has a lot of blood and exudate from the incision, he or she should seek medical attention promptly; after the condition is stabilized, you can use saline diluted benzalkonium chloride solution to wipe around the mouth and other parts of the mouth, especially where the patient’s skin flap and normal tissues meet. If the patient is tracheotomized, then the usual attention should be paid to cleaning the tracheal sleeve with saline, but prior guidance from the specialist nurse is required.
