Will Botox help to shrink my temporalis muscles? (Photo)

Great question. The answer is yes probably. Whilst it's not the main reason for injecting this site (usually one of the areas injected in migraine sufferers), it does tend to occur. 
I would also rate you that none of my patients have noted loss of strength of bite. The muscle is one used in eating. 

Good luck. 

Yes Botox can temporally decrease the prominence of your temporalis muscles. However it would require repeated injections. Botox is not designed to permenantly fix the sides of your head however there are some procedures that could possibly address your concerns. There is a possibility to get what you are looking done. Every patient has different results.

Good afternoon, 
A neuromodulator works by interrupting the pathway from the nerve to the muscle, this will then decrease the size of the muscle. You would require a face to face review to ensure that this is a appropriate treatment for you. The temporalis muscle is responsible for chewing so you should see an expert injector to ensure you have a thorough assessment as to the dose required. Good luck.

Botox can be used to slim the masseter. It will take 1-2 weeks for final results with Botox. Hope this helps.

Botox can be injected into these areas to create a softer look. The botox will essentially relax the muscles creating the appearance of atrophic muscles. The results will last up to 3-4 months hence you will have to re-inject roughly 3x per year. When administered by an expert injector you shouldn't have an issue with too much laxity. The biggest issue will be muscle weakness if you inject too large doses, which will be required in larger muscles (as compared to cosmetic forehead/face injections) See an expert. Best, Dr. Emer. 

Thank you for your question. Botox is a purified protein used to address wrinkles associated with facial expression. When injected into the skin Botox will relax the muscles and smoothen out the overlying wrinkles. The most common areas of treatment are in the upper face. These include the horizontal lines seen on the upper forehead when one raises the brows, the vertical lines seen between the brows when one frowns (frown lines), and the crow's feet seen around the eyes when one smiles. It is difficult to make an assessment without a formal exam in the office where I can view the skin in multiple angles and observe wrinkles formed with facial expression. However, I hope the information provided here is useful.

Yes, the temporalis muscle will atrophy with regular treatment using a neuromodulator like Botox or Dysport.

However, I hope the information provided here is useful.The temporalis is a muscle on the sides of the upper head in the temple area which is used for biting and chewing. It is commonly treated when performing Botox treatments for migraine headaches and sometimes in the case of TMJ pain. Any muscle that is treated with Botox will likely get smaller. In the photograph shown here, it is difficult to tell if the bulge is from the muscle or the bone(s) in the skull. Therefore, if I had a patient who looked like the person in this photograph, I would examine the bulge with and without biting. This will tell where the muscle is. It can also be felt. If the bulge is from the muscle, the I would say Botox treatment would be appropriate here.With any injection, there are risks such as pain, bleeding, bruising, redness, swelling, tenderness, and infection. We take special precautions to minimize these risks such as using a painless technique. We also treat bruises with a laser as early as the next day. Bruises usually resolve within two weeks if untreated. After a laser treatment bruises usually resolve in 1-3 days, but may still take two weeks for full resolution. In addition to these risks, with Botox there is also a risk that the product spreads or diffuses to nearby structures. Spread to nearby muscles can lead to side effects such as the temporary appearance of droopy eyelids or a temporary asymmetric smile.

After a Botox treatment, I recommend that my patients avoid heat exposure, alcohol consumption, and strenuous exercise for 24 hours and not lie down flat for four hours. This is because all of these activities may possibly lead to the movement of the product and consequent side effects such as droopy eyelids. Although there have been no definitive studies shown that these actually occur and some physicians do not provide such aftercare instructions, in the absence of data I err on the side of caution and recommend that my patients avoid such activities.

Please consult with a doctor for specific recommendations. Good luck!

Any muscle group that gets regular Botox injections will atrophy in size over time. Good luck from New York City

Thank you for your question.You are correct in your thoughts about Botox being injected into the temporalis muscle to produce some atrophy or retraining of the muscle overtime and lead to a decrease of its size.  If you chew gum consider decreasing doing so as the temporalis is a muscle used in chewing.Andre Levesque M.D.
