The masseter muscle located in front of parotid gland is covered by parotid gland. The most common reason why masseter factors affect the appearance of dynamic face is benign hypertrophy of masseter (often accompanied by hypertrophy of mandibular angle). Masticator hypertrophy of mandibular angle may be congenital or acquired. Usually only one tooth is used to chew food, which leads to benign hypertrophy of masseter muscle. Masticator hypertrophy can be on one side or both sides, resulting in hypertrophy of mandibular angle. Adult is a square face.

Some people's bad face is not caused by mandibular angle, but by the overgrowth of masseter muscles protruding from both cheeks.

Suitable for people:

Masseter hypertrophy

Methods 1: part of the masseter muscle was surgically removed.

Generally speaking, from the appearance, the face of patients with masseter hypertrophy is mostly square, so it is also called "square face". Patients were asked to close their teeth and touch the bilateral masseter muscles at the mandibular angle to feel the contraction amplitude and thickness of the masseter muscles. The masseter muscle of patients with masseter hypertrophy can obviously feel the masseter muscle amplitude is larger and the masseter muscle is obviously thickened during contraction. When examining the masseter muscle, we should pay attention to the hypertrophy of the mandibular angle and whether the mandibular angle is everted. Because of the operation, the patient fasted from the mouth 2 days after operation, and the physiological needs were supplemented by infusion.

The reason why surgery routinely avoids "menstrual period" is because the coagulation mechanism in the menstrual period is poor and it is easy to bleed after surgery. Postoperative hematoma infection is easy to cause swelling, and the swelling period is obviously prolonged.

Postoperative care and precautions: Generally speaking, after fasting for 2 days, use antibiotics, hemostatic drugs and enough physiological fluids. There are obvious differences among individuals. Generally, the swelling is most obvious at 3 days after operation, and then it gradually subsides at about 65,438+00 days after operation. The obvious swelling basically subsided within one month after operation. Try to avoid irritating diet and hard diet, and there will be temporary difficulties in opening your mouth after operation. Generally, don't practice opening your mouth deliberately.

Method 2: Botulinum botulinum type A injection.

This method can treat bilateral masseter muscle hypertrophy and reduce masseter atrophy through neurotrophic effect. Generally, 1-2 injection points are selected for injection on each side. Advantages: Masseter muscle injection 1 month, observation of masseter muscle atrophy and face changes, simple and easy to operate. Disadvantages: If the dosage and injection site are not well controlled, there will be local adverse reactions, mainly including excessive weakness of masseter muscle and stiff facial expression, which are caused by the spread of carnosine 0 to adjacent muscle tissues. Of course, choosing a regular plastic surgery hospital can be completely avoided in this respect; The effect of each injection only lasts about half a year. Running time: 10 minute.

Precautions for operation:

1. Women during pregnancy should not be injected.

2. Pay attention to avoid frequent chewing exercises (such as chewing gum and cracking melon seeds). ), and the face-lifting effect can be maintained for a long time.
