Dalian Makeup -- Because the surgery mainly involves the removal of the masseter muscle, and the resection of the masseter muscle may cause trismus. Since the amount of muscle removed is not easy to control, it can lead to errors in symmetry and damage to branches of the facial nerve, among other issues. This has led some Western scholars to focus a large amount of research on drug treatment for "masseter hypertrophy." In 1994, Smyth et al. reported on their experience using botulinum toxin to treat bilateral masseter hypertrophy, considering this a revolutionary new method. Smyth suggested that this technique be used as a routine treatment for "masseter hypertrophy." Botulinum toxin injection works by causing atrophy and reduction of the masseter muscle through its neurotoxic effects, making the treatment more thorough and solving this difficulty. This has enhanced patient satisfaction and significantly increased the number of patients seeking treatment. The combination of botulinum toxin injection and mandibular angle surgery has achieved excellent results, with 1+1 being greater than 2. Combined with facial liposuction, zygomatic reduction, and narrowing methods, significant improvement can be made to a chubby face.
Generally, 1-2 injection points are chosen per side. The injection should be done as slowly as possible, and no local massage or other special treatments are required after the injection. Normal chewing activity will allow the medication to gradually diffuse within the muscle tissue.
1. What is botulinum toxin? Is it toxic?
Key reminder: Every girl dreams of having an attractive oval-shaped face. Although genetic factors are limited, with the development of modern cosmetic surgery, if you have the courage, you can own a charming small face. Today, we have collected eight common questions about botulinum toxin for facial slimming. Hopefully, this will provide useful reference.
5. When does type A botulinum toxin take effect? How long does the effect last?
As a muscle injection drug, botulinum toxin has no obvious side effects and has more advantages compared to traditional surgical methods. After injecting type A botulinum toxin, local adverse reactions mainly include excessive weakness of the masseter muscle and corresponding symptoms caused by the diffusion of botulinum toxin to nearby muscle tissues. These clinical manifestations are related to the injection site and the dose of injected botulinum toxin. Some patients may experience fever, discomfort, and fatigue after the injection. Normally, these clinical manifestations are transient and resolve on their own within a few weeks.
3. Why use botulinum toxin to treat masseter hypertrophy instead of directly removing the muscle?
Besides botulinum toxin injection and mandibular angle arc osteotomy, there are also facial liposuction, zygomatic reduction, and narrowing methods. Combined treatment can significantly improve a chubby face.
Women consider an oval face shape to be beautiful and often seek plastic surgery due to enlargement in the mandibular angle area. Tens of thousands of cases of mandibular angle arc osteotomy occur each year. More than 90% of patients have benign masseter hypertrophy and hope to reduce it simultaneously. Since it is difficult to control the amount and depth of muscle removed during surgery, the results are often less than ideal and can increase the risk of bleeding, hematoma, infection, asymmetry of both sides of the face, facial nerve paralysis, trismus, and prolonged muscle spasm, among other serious complications.
After botulinum toxin injection into the masseter muscle, the effect usually lasts around 6-8 months, and the masseter muscle will gradually recover after the drug's efficacy fades. However, after multiple injections, the duration of the effect will become longer, generally lasting about one year after 3-4 injections. In some cases, even without further injections, the masseter muscle effect can be maintained. Botulinum toxin can be repeatedly injected without accumulating toxins.
Only products that stand the test of time are good products. People have been using botulinum toxin for beauty purposes for over 20 years. In 1986, the Canadian Carruther couple discovered its excellent wrinkle-reducing effects while treating blepharospasm with botulinum toxin. Subsequently, they treated forehead wrinkles, glabellar lines, and crow's feet with botulinum toxin through a series of trials and reported their findings in 1992. Thus, the Carruther couple became pioneers and inventors of this technology.
8. What are other comprehensive treatments for chubby faces?
7. Will the treatment recur?
Two weeks after injecting type A botulinum toxin into the masseter muscle, patients can feel a decrease in chewing force when chewing hard, with no obvious bulging or fatigue of the masseter muscle. Local palpation of the masseter muscle also shows no significant contraction. Generally, one month after injecting type A botulinum toxin, shrinkage of the masseter muscle and changes in face shape can be observed. The effect usually lasts from six months to one year.

4. How is botulinum toxin used?
2. How long have people been using botulinum toxin?
Botulinum toxin is not as terrifying as its name suggests. Many beauty clinics call it biological wrinkle removal or gene-based wrinkle removal to alleviate people's fears. Botulinum toxin is a biological product that can be produced on a large scale through genetic engineering methods. Due to its neuroblocking action, it is commonly used in neurology, ophthalmology, plastic surgery, and cosmetic surgery. The current dosage is only a fraction of its maximum safe dosage, so it is very safe.
