Therefore, even if the injectable filler type of surgery should not be negligent, in the tertiary hospital to do these words will be much more secure. Then someone has to ask, can regular hospitals also do these minor medical procedures? Generally speaking, yes, for example, medical aesthetics is often referred to as a slimming injection, which is an alias for the botulinum toxin that we will use in the clinic, and botulinum toxin is widely used in the treatment of facial muscular spasm. Unlike the purpose of medical aesthetics, the injection of botulinum toxin is not for the purpose of slimming the face, but for the purpose of relieving the symptoms of facial muscle spasm. How does it work? When blood vessels and facial nerves are in close contact, the constant pulsation of the blood vessels causes the facial nerves to continuously send out impulses, causing the facial muscles to constantly twitch, and the sensory nerves of the facial muscles feed back the twitching phenomenon to the cerebral cortex, and the patient feels uncomfortable in the face. Botulinum toxin can act on the nerve and muscle contact, and to the site of the electrical signal of the nerve, attenuate the nerve like muscle transmission of impulses. Excessive injections can lead to facial paralysis: However, Botox requires an amount, not that the more the better, a small amount of Botox can have the function of beauty and slimming, too much can lead to facial paralysis. This is because the process of playing botulinum toxin is supposed to sacrifice the ability of facial muscles to prevent facial twitching, too much is possible to cause facial paralysis, botulinum toxin injection unit should be based on the patient’s situation quickly to determine the appropriate amount of the best, too little also has no therapeutic effect. This is a very test of the physician’s professional level and technical experience. But it is worth noting that even if the conditions are met, the recovery is also very good, the patient will appear with the passage of time, the prolongation of the condition, the efficacy of the drug gradually decline or even no efficacy of the situation, so this is not the best way to treat facial muscle spasm. The medical profession generally believes that facial muscle spasm is best treated with microvascular decompression surgery. Microvascular decompression surgery for facial muscle spasm Microvascular decompression surgery refers to the magnification of intracranial nerves and blood vessels through a high-powered microscope and then operation, the shims are placed between the nerves and blood vessels, so as to relieve the pressure of blood vessels on the root of the facial nerve, and restore the normal function of the facial nerve, so as to alleviate the symptoms of facial muscle twitching. This technology has the advantages of minimally invasive, high safety, remarkable effect and low recurrence rate, especially can completely retain the blood vessels, nerve function, has become the world’s most effective treatment of facial muscle spasm, which is also the only way to completely cure facial muscle spasm.
