Will Botox injections before a temporal brow lift affect my results in a negative way?

I am scheduled for a temporal brow lift, in May. If I were to get Botox before and it lifted my lateral brow, would that affect the end results of my surgical brow lift by the surgeon not lifting as much as he would have (had the eyebrow been in its natural drooping state without the Botox). When the Botox wears off, the brow will droop back down and maybe,had the Botox not been in the brow when operated on, the surgeon would have pulled it up more... does this make sense as a concern?
