Cheek Frozen After Botox to the Eyes

Botox typically influences about a square centimeter around it's injection point, but that varies depending on concentration and technique.  The obicularis oculi muscle is most responsible for the formation of crows feet, which is a thin superficial ring-like muscle.  Most of the time that muscle is effectively treated with botox to selectively soften crows feet.

The zygomaticus muscles are deeper, and a bit lower on the face than the usual injection sites for botox.  It sounds like somehow these zygomatic muscle(s) were affected by the botox as well.  There are times when a very weak peripheral effect from botox causes things like this,  and the body compensates to improve things within 2-3 weeks.  If it does not seem to be softening by then, you might have to wait out the full botox duration of 3-6 mos. 

What you are experiencing is very rare, so I would not give up on trying it one more time in the future for crows feet once you are comfortable again.  The injection sites just need to be higher, and more superficial.

Botox will do what you tell it to do.

If it is placed in the orbicularis muscle near the cheek, it will deactivate that muscle.  One of the functions of the orbicularis muscle in this region is to elevate the cheeks.

If that patient has any underlying differences in muscle strength, or if the Botox was unevenly injected, a very significant asymmetry can result.

Botox does not "get rid of wrinkles" by relaxing muscles; it relaxes functional muscles.  A thorough understanding of the interrelational functionoing of muscles is important.

If the errant Botox was a direct hit, it will probably take 3 months to improve.  If it resulted from inadvertent Botox in a watershed area, improvement should be quicker.

The BOTOX will wear off.  It could take several months.  There is honestly no treatment other than waiting.  This type of abnormal weakening with BOTOX is interpreted by the emotion centers in the brain that rely on feedback from the brain as a bad feeling.  In other words, it makes you feel bad even if the change in appearance is minimal.  Probably a good idea to find a new BOTOX injector.
