The essence of face-lifting needle face-lifting is to treat masseter hypertrophy with botulinum toxin injection. It is found that it is difficult to grasp the amount and depth of muscle resection in mandibular angle surgery, which not only leads to unsatisfactory results, but also increases the chances of bleeding, hematoma and infection, leading to serious complications such as asymmetry on both sides of the face, clenched teeth and long-term muscle spasm. 1994, Smyth et al reported the experience of treating bilateral masseter hypertrophy with botulinum toxin A, which was considered as a revolutionary new method. Botulinum toxin injection can reduce occlusal atrophy by denervation and make the treatment more thorough.

The effect of face-lifting needle is not 100%. After several injections, a few people will produce antibodies to botulinum toxin, making future injections ineffective. Because of chewing habits, there will still be slight asymmetry on both sides after injection. A few people may not be sensitive to drugs, so the effect is not obvious, and they need to return to the clinic after 2 weeks. Botulinum toxin can be recovered after injection, that is to say, after 3 to 6 months, it needs to be injected again to maintain the effect.
According to the three reasons for big face, there are also three methods for thin face, as follows:
1, facial bones are widely developed, and this thin face should be achieved by osteotomy.
2. The facial masseter muscle is developed and hypertrophy. This face-lifting is achieved by removing the masseter muscle or injecting a face-lifting needle to make the fibers of the masseter muscle thinner.
3, facial fat accumulation, this face-lifting needs to be achieved by facial liposuction.
Therefore, for the symptoms of big face, the face-lifting needle is not omnipotent. Face-lifting acupuncture can only be aimed at the second kind of "big face" in the original country, that is, people with Chinese character face and masseter muscle hypertrophy, and cannot be aimed at people with simple mandibular hypertrophy.
Comparison between masseter muscle resection and face-lifting needle;
Partial excision of masseter muscle has certain surgical trauma, which needs some time to recover, but the maintenance effect is long. The operation was performed in the mouth. First of all, the bacteria in the oral cavity should be thoroughly disinfected to reduce the postoperative infection rate. When the masseter muscle is removed, the medial surface of the masseter muscle should be removed to avoid damaging the mandibular marginal branch of the facial nerve. The amount of masseter muscle resection depends on preoperative examination, and the amount of masseter muscle resection generally does not exceed one-third of the thickness of masseter muscle.
Face-lifting needles are usually injected at 1 ~ 2 injection points on each side, and the injection process takes about 20 minutes, so there is no need for anesthesia, and the injection trauma is small and the recovery is fast. 2 ~ 3 weeks after injection, the masseter muscle began to contract, and the face-lifting effect appeared. The effect can last for about a year, and then gradually recover. After several injections, the muscles gradually contracted and formed.
