Cannot Smile After Botox for Migraines

Cheek is not the location to inject Botox for Migraine Headache.Best,Ali Totonchi MD

There are seven key migraine trigger points that are amenable to injection with Botox. The first task for your surgeon is to determine if you indeed meet the International Headache Society criteria for chronic migraine headaches, and then to determine your migraine trigger point(s). The anatomic areas amenable (and FDA approved) for the injection of botulinum toxin are:CorrugatorProcerusFrontalisTemporalisOccipitalisParaspinal, andTrapeziusThese correspond closely to the Frontal, Temporal and Occipital trigger areas that are associated with migraine headaches. Injection into other areas are not indicated for the treatment of migraines. Nonetheless, the treatment effect is limited and should return normal muscle function within 3-4 months.

As stated earlier, you shouldn't inject Botox in the cheeks because it will affect the movement of the zygomaticus muscle which raises the corners and the upper lip.  There is nothing which can be done except let the Botox wear off over the next 3-4 months.
