For aesthetic reasons, the size and shape of the bite muscle can only be changed, and the main methods include botulinum toxin injection and surgical excision.1. Botulinum toxin injection: Botulinum toxin mainly acts at the nerve and muscle junction, and after botulinum toxin injection, the signal of the nerve cannot be transmitted to the bite muscle, and the bite muscle will be gradually paralyzed and slowly atrophied. Generally Botox injection 2 weeks after the start of the effect, 2-3 months when the best effect, but the duration will not be too long, Botox metabolism will end after about six months, if you want to continue to thin the bite muscle, you need repeated injections, generally every six months, a total of three injections, you can achieve a stable state; 2, surgical excision: mainly in the mouth to make incisions, according to the patient’s requirements for the elimination of the effect. The excised muscle tissue will not be regenerated, thus the purpose of reducing the bite muscle can be achieved, and the effect can be maintained for a long time. In short, the above methods have certain risks, it is recommended that you must choose to operate in a regular hospital.
