What is Botox jaw reduction?

Botox jaw reduction in Singapore is a relatively common procedure. Masseter muscle hypertrophy presents as tissue enlargement at the angle of the jawline. Hypertrophy describes an increase and growth of muscle cells as the result overactivity. While masseter hypertrophy is more common in certain ethnic groups, it can result in facial pain, headaches and appear cosmetically unsightly.

Masseter hypertrophy can also result from bruxism.

Bruxism is a medical condition where an individual would unconsciously clench and grind their teeth. This can happen during daytime and while asleep. In addition to masseter hypertrophy, individuals may suffer from facial pain, worn out teeth, jaw dislocation and other dental problems down the road.


Botox jaw reduction

Botox masseter reduction, a specialized non-surgical procedure, has gained recognition for its dual benefits in aesthetic enhancement and functional relief. This technique involves the precise injection of Botulinum Toxin Type A into the masseter muscles, which are responsible for jaw clenching and chewing. A skillful and experienced injector of more than 15 years, Dr Ng. believes in creating a customized treatment plan that meets your unique situation to give you the best results.

What Causes Masseter Hypertrophy?

The underlying causes of masseter hypertrophy are numerous, and factors affecting an individual may differ from another. From dietary habits such as the propensity at chewing nuts or hard foodstuff, masseter hypertrophy may also result from genetic factors. 

While the causes of chronic bruxism remain unknown, stress, and abnormal masseter muscle function may play a role. Some studies postulate that the enlargement may be due to a compensatory lack of certain muscle fibers.

Benefits of masseter reduction

Aesthetic Benefits: The masseter muscles can become hypertrophic due to excessive clenching or grinding of teeth, leading to a more square-shaped jawline. By carefully administering Botox to these muscles, their activity is reduced, resulting in muscle relaxation and a subsequent slimming effect on the lower face. This can create a more balanced and harmonious facial appearance, particularly desirable for individuals seeking a softer, more oval-shaped face.

Functional Benefits: Beyond aesthetics, Botox masseter reduction can significantly alleviate discomfort associated with conditions such as bruxism (teeth grinding) and temporomandibular joint disorder (TMD). Patients often report a reduction in jaw pain, headaches, and overall tension in the jaw area following the procedure. This therapeutic aspect underscores the procedure’s value in improving the quality of life for individuals suffering from these chronic conditions.

How is Masseter Hypertrophy diagnosed?

While most cases of masseter hypertrophy can be made on clinical grounds, some cases do require further evaluation. Imaging such as MRI or CT scans may be used in some cases to confirm clinical suspicion. In addition, studying the muscle activity and muscle thickness using electromyographic and ultrasonographic studies respectively may be utilized. A muscle biopsy is rarely needed except in unusual circumstances.

Masseter Reduction Treatment Options:

There are variable masseter reduction treatment options, each with its benefits and potential side effects. When considering the most appropriate treatment, you would need to determine if the treatment fits with your lifestyle choice, tolerance and budget. Treatment options include:

  • Drugs: muscle relaxants, anxiolytics and anti-depressants etc.
  • Dental intervention for correction and prevention.
  • Botulinum Toxin A injections to the masseter muscles.
  • Radiofrequency volumetric reduction.
  • Surgery

How does Botox Jaw Treatment work?

The main action of botulinum toxin treatment is to inhibit activation of the masseter muscles. A period of muscle inactivity will lead to muscle atrophy (smaller muscle mass). This reduces the facial angle and gives rise to a slimmer and more contoured lower face over time. There are some studies to suggest that the weakened masseter muscles will lead to changes in the mandibular bone. This means that the dramatic effects from this treatment are not only due to a reduction in muscle bulk, but also changes in the jaw bone structure. 

How Is The Procedure Done?

After a consultation, a clinical examination will be carried out to determine suitability for the procedure. You will be asked to clench your teeth to accentuate the masseter muscles on both sides. After cleansing the area, and applying numbing cream, 3-5 injections are placed into the bulkiest portion of the masseter muscles. You are advised not to lie down for 4 hours post-procedure, avoid alcohol for 72 hours, and repeatedly clench your teeth for 20 minutes after the procedure to maximise the treatment effects.

How long do the results lasts?

Most individuals will be able to notice modest results by 6 weeks. The results lasts for 4- 6 months, but varies among individuals. It is important to reduce excessive and habitual chewing so that you get longer lasting results. Repeated treatments will bring about longer results as the muscles are already weakened.

Who Is Not A Good Candidate For Botox Jaw Reduction?

  • Pre-existing medical conditions causing muscle weakness e.g. multiple sclerosis, myathenia gravis
  • Infection at injection site
  • Previous allergy or hypersensitivity to Botulinum Toxin treatments
  • Pregnancy or breastfeeding

What's the Difference Between Botox and Dysport?

They are both Botulinum toxin Type A products which function to reduce neurotransmitter to the target muscle. There is not much clinical difference between them except:

  • Different units: 1 Unit of Botox is about 2.5 units of Dysport
  • Pricing: Dysport tends to have a more favourable price.
  • Diffusion: Dysport may be able to diffuse along a wider area which is advantageous to the bulky masseter muscle.

Besides these differences, the onset of action, longevity of effects and even side effect profiles are similar.

How many units do i need?

We have a variety of botulinum toxins that can be used effectively for masseter reduction facial contouring. There is very little clinical difference between the major brands in terms of treatment results, and longevity of effect.  The amount of units injected will depend on your masseter muscle bulk. For individuals starting the procedure for the first time, we advise starting with a moderate amount. This will achieve good results in the majority of cases.

To get an idea of how much botulinum toxin we use, here is a rough guide.

  • Botox: 24-30 units per side.
  • Dysport: 60-75 units per side.

The amount varies from person to person. Generally, men and individuals with moderately-severe masseter hypertrophy would require more units. Please contact us for more details on the pricing.

Frequently Asked Questions or Botox Jaw Reduction

Good candidates for Botox masseter reduction are individuals who have enlarged or overdeveloped masseter muscles, often resulting in a square or overly prominent jawline. Candidates should be in good overall health and have realistic expectations about the results of the procedure.

The benefits of Botox masseter reduction include:

  • Slimming and contouring of the jawline
  • Reduction in the size and prominence of the masseter muscles
  • Improvement in facial symmetry
  • Relief from symptoms of bruxism (teeth grinding) and temporomandibular joint (TMJ) disorders
  • Non-surgical and minimally invasive procedure with little to no downtime

Botox masseter reduction is typically well-tolerated by most patients and is associated with minimal discomfort. The injections may cause a slight pinching or stinging sensation, but this is usually brief and mild. Topical anesthetic cream or ice packs may be applied to the treatment area beforehand to minimize discomfort.

The effects of Botox masseter reduction typically last for about 4 to 6 months, although individual results may vary. Over time, the masseter muscles gradually regain their strength and size, requiring repeat treatments to maintain the desired results.

Side effects of Botox masseter reduction are usually mild and temporary, including redness, swelling, bruising, and tenderness at the injection sites. Uncommonly, there may be compensatory temporal muscle hyperactivity after the procedure. In rare cases, more serious complications such as asymmetry, muscle weakness, or difficulty chewing or speaking may occur.

Some patients may begin to notice improvement in jawline contouring within a few days to a week after the procedure, with optimal results typically visible within 2 to 4 weeks.

Yes, Botox masseter reduction can be combined with other cosmetic procedures such as dermal fillers, chin augmentation, or facial contouring to achieve more comprehensive facial rejuvenation or enhancement.
