Functional training after tongue cancer surgery is mainly to increase the mobility and flexibility of the tongue, make the tongue stretch forward as much as possible to play the role of extension, and allow the tongue to move left and right, which can have a certain compensatory effect on the function when the patient speaks, eats and swallows. Pronunciation is mainly to do tongue-palate, curl tongue and other training to improve the clarity of the patient’s speech after surgery. The tongue is a functional organ and has a greater impact on the patient’s pronunciation, swallowing, chewing and other functions. The training of tongue function after surgery is also more important, and functional training is usually done after the wound heals.
