Face-lifting needle, that is, botulinum toxin A injection, mainly acts on muscle tissue and is called face-lifting needle because it is often used to solve masseter hypertrophy. Face-lifting needle Face-lifting needle Face-lifting needle is essentially 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. Because it is difficult to grasp the amount and depth of muscle resection in mandibular angle surgery, the effect is not ideal, which is easy to increase the chances of bleeding, hematoma and infection, leading to serious complications such as asymmetry on both sides of the face, clenching 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 local adverse reactions after injection of face-lifting needle mainly include the excessive weakness of masseter muscle and the corresponding manifestations caused by the spread of face-lifting needle to adjacent muscle tissues, and these clinical manifestations are related to the injection site and the dose of face-lifting needle. Individual patients with thin face found fever, discomfort and fatigue after injection of botulinum toxin. Generally speaking, these clinical manifestations are short-lived and disappear naturally within a few weeks. After face-lifting needle injection, the general face-lifting effect can be maintained for about one year, and then there is the possibility of recurrence, but the face-lifting needle can be injected again. 1, myasthenia gravis patients 2, neuromuscular diseases patients 3, allergic constitution 4, pregnancy and lactation 5, drinking (including beer) within one week 6, taking aspirin or other antipyretic and analgesic drugs orally within two weeks 7, using aminoglycoside antibiotics (such as gentamicin and streptomycin) 8, mental disorders, poor self-control ability 9, unable to lose face. 1 1, patients with abnormal adrenal secretion; Face-lifting needle of Shanghai Ninth Hospital: 7 15 yuan/agent X 2 (medicine fee) +700 yuan/prescription (operation fee) X 2 = 2830 yuan+registration fee = (about) 3,000 yuan (domestic). Side effects: Baidu yourself and see how many real people have asked about their face-lifting needles. I'm afraid there are far more people hitting this than you think, but everyone is letting others think that they are born beautiful and keep silent. Almost all side effects are surgical problems or maintenance problems or their own physique is not suitable for botulinum toxin, but that is not a side effect. But as for the long-term side effects, it is not clear whether there will be side effects on future generations and our own people when we get old. Bottom line: There are no side effects for the time being, and it is unclear for a long time.
