Can Temporalis Muscle Wasting from Botox Be Reversed? (photo)

So sorry to hear about your frustration and difficulty with Migranes. It can be such an awfull disease. 

With regards to the temporalis wasting, think of it like any muscle in your body....Use it or loose it! BUT. Its not permanent. Botulinum toxin basically prevents your muscle from working so it "atrophies" which basically means, it gets smaller. Its the same as if you put a cast on your leg for 4 months. When you take it off, your muscles are tiny. But after walking around and some physiotherapy, you get back to normal. The same is true in this case. Once the medication wears off, its like taking the cast off. 

I would highly recommend seeing a physiotherapist as well as talking to your dentist as you want to ensure that as you rebuild your muscle you do this in a gentle, symmetrical way.

I would be surprised if after a few months you'll notice the muscle come back quickly. the temporalis is a very powerfull muscle and your body basically needs to learn how to use it again and then start to build up its bulk. 

Try to stay positive. 

As
Botox is only temporary, your situation should return to normal with time! You need to follow with your doctor. If you don't have TMJ (temporomandibular Joint) issues, I would consider chewing gum to exercise the temporalis to build it back up You should see a return to normality within 6-9 months. Do this only under the direction of your doctor to evaluate whether or not there are any other neurologic deficits, though it seems to be most related to the botoxGood
luck!

If the muscle was weakened too much, when the Botox wears off, it should go back to normal. If not, fillers like Sculptra, Radiesse, or Juvederm can replace lost volume in the temples nicely.
