Can Botox injected under the eyes cause flatness/push down/immobility of movement in the upper mid-cheek area?

Yes cheeks can be affected if botox is injected inappropriately in this area.  Please speak to your physician.  This will improve after 2-3 months. Best, Dr. Emer.

Botox is a medication that temporarily weakens muscles. It is injected to the side of the eye to weaken the muscle (orbicularis muscle) that makes crow's feet. When injected too far below the eye, the medication can be absorbed by other muscles, including the one that lifts your cheeks (zygomaticus muscle). This can produce an odd smile or flat face. The good news is that this is temporary. The bad news is that you will have to wait 3 months to start seeing the motion come back to your cheeks. Filler may be a safer option in your cheeks. 

The zygomaticus minor and major as well as the levator labii superioris muscles could  be affected impacting your cheek and smile.  The puffiness in the eye is seen with decreased tone of the pre-septal orbicularis oculi muscle.  The good thing is it will wear off eventually.   Regards.

This is caused by the Botox affecting the Zygomaticus muscle. If not done close enough to the orbital rim, the Botox can migrate to this muscle and affect the pulling up during smiling of the upper lip. There is nothing that can be done, you just have to let the Botox wear off in about 2-3 months.

Hello Rmjgc5,The answer to your question is yes, Botox can cause the result you are seeing.  It is not commonly  injected below the eye, but it can be to help soften some of the wrinkles.  If injected too low then you can start affecting the muscles that help to raise the mouth (which is why it looks particularly strange when you smile).  It can also over weaken the muscle that encircles the eye to help it close but this muscle also helps to hold back the fat that is around the eye.  If it is weakened it can cause the fat to push forward and give a puffy look.  The good news is these results are only temporary.  The bad news is they can last for a few months.  I'd recommend in the future that you consider consulting with a facial plastic surgeon who performs his or her own injections.  Although never having an unwanted result can never be guaranteed, there is usually a better appreciation for the anatomy when you have a physician injector which does minimize the risk of a less than ideal outcome.  I hope this helps and good luck.  

it may be the injection was too low onto the cheek and weakened the Zygomaticus major muscle. this should wear off in a couple of weeks but be sure you tell your doctor about it if you have it done again
