Forward the video to: the effect of face-lifting needle must have been heard by everyone. Face-lifting needle has a good effect and is popular all over the world. However, some people still don't believe it. They are afraid that their faces will swell after the face-lifting needle. As we all know, it is a cosmetic method in maxillofacial plastic surgery, and it can be simply thinned without surgery. So let's take a look at the effect of face-lifting needle. Will the face swell after the operation? How is the effect of face-lifting needle? The essence of face-lifting needle face-lifting is to treat masseter hypertrophy with botulinum toxin injection. Women are beautiful in oval shape, and often need plastic surgery because of the hypertrophy of mandibular angle. More than 90% patients are accompanied by benign masseter hypertrophy, hoping to shrink at the same time. 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. Experts say that if the operation is careless, the face will swell, and of course, poor postoperative care will also cause the face-lifting needle to swell. Accompanied by facial swelling, there may be slight cyanosis locally, which usually disappears by itself in about 7 days; It doesn't feel anything, and it is not necessarily invalid. Some people just don't respond at all, and their faces gradually lose weight in a month or so.
