Can Botox That is Injected Between Eyebrows Go into Sinuses and Drain Down Throat ?

...you have a personal history of a facial fracture, frontal sinus fracture, or frontal sinus surgery. In any of these scenarios, you could theoretically have a dehiscence or absence of the bony wall of your frontal sinus. This could make it anatomically possible for a 30 guage needle to penetrate your frontal sinus, and allow Botox to drain into your throat.

I don't see a connection to the sinuses from botox injections, although theoretically if someone were to inject near the corner of the eyelids, deeply, so that the fluid would get in the tear duct (I have never heard of this!) then it could drain down the throat. I can't imagine the latter occurring, nor the possibility of drainage into the sinuses.

Unless you had a previous fracture or dehiscence of your frontal sinus bone, and unless your doctor injected the Botox through the fracture edges or fibrous union into the frontal sinus, Botox cannot get in your frontal sinuses.  This scenario would be so exceedingly unlikely that it should not concern you.  Botox, however, can affect swallowing if used in extremely high doses (overdose situations), which are not used in cosmetic situations.  To avoid unexpected results from Botox, make sure that your doctor is highly experienced in facial anatomy and in Botox administration and titration.
