The bite muscle is the main executive muscle of the biting action and is an important chewing muscle in the body. If the usual chewing time is too long, too many times, or chewing with greater force, will lead to muscle production. The bite muscle is too large and its thin face methods include the following: 1, change bad habits: try to reduce the number of chewing, eat less hard, difficult to chew food, such as chewing gum, beef jerky, betel nut, nuts, etc.; 2, injection face slimming needle: that is, Botox, known as the “thin face artifact”, for the bite muscle to play a role. In the bite muscle injection of thinning needle, can block the nerve and muscle conduction, so that the contraction force of the bite muscle is weakened, so that part of the muscle gradually atrophy, so as to achieve the purpose of thinning the face. Usually the effect begins to be obvious after 1-2 weeks of injection and can be maintained for about 4-6 months, if you want to achieve long-term results, you need to repeatedly inject 5-6 times; 3, bite muscle resection: the procedure is to make an incision in the mouth and remove the excess bite muscle after suturing. Before the surgery, an MRI and other tests are needed to understand the condition of the bite muscle hypertrophy, and then the bite muscle removal plan is formulated according to the test results and the patient’s face shape. Because it is an invasive procedure, it requires a longer recovery time, so it is now used by fewer people.
