Can recent PDO threads and Botox in forehead change the results of an upper bleph?

In reality, the effects of Botox and PDO threads on the position of the eyebrows is minimal. That is why the use of PDO threads in the U.S. by cosmetic practices is not widespread. Surgeons who routinely perform blepharoplasty surgery use multiple methods to determine the correct amount of skin removal taking into consideration multiple factors including recent Botox or threads. There is no reason to delay surgery. 

The lift of brows from Botox or threads can hamper the correct estimation of amount of skin to be removed from the upper eyelids. Make your surgeon aware of the procedures you have done and at the minimum wait for the Botox to wear off. During consultation your doctor might have you relax your brow by pushing on it and then assessing the exact amount of extra skin in the upper eyelids.RegardsDr. J

You are asking a good question!  For patients of mine who present for upper eyelid blepharoplasty and brow lift I routinely inject Botox preoperatively. The effects of PDO threads in the forehead are going to be short lived (probably around 9 months) but during the time that they are in place the eyebrow will be elevated and that may change the amount of skin available to remove during upper eyelid blepharoplasty.  I would recommend waiting until the PDO threads effects have diminished and then have upper eyelid surgery along with a brow lift for best results.

yes, any work on the forehead can change the results of a blepharoplasty procedure. Probably best to separate these procedures out approximately six months. It does not matter which procedures come first or last.
