How Will Botox Affect Blepharoplasty Result?

Botox should not interfere with upper eyelid surgery per se. However when judging eyelid position and brow position it is best not to have Botox on board.
Also, Botox can diminish orbicularis function and should be used with caution after lower eyelid surgery or cheeklift procedures.

Botox should not effect your blepharoplasty results. In fact, many surgeons prefer to treat their patients with Botox just prior to blepharoplasty. This, in theory, relaxes the obicularis muscle allowing for better skin healing.

It all depends on if the Botox was still active. If you have functioning Botox at the time of the belpharoplasty (which means that the orbicularis muscle was partially paralyzed leading to an elevation of the lateral brow) then when it wears off, you may get a little extra fullness laterally where the skin is no longer stretched from the elevation of the brow. However, in all likelihood, you are going to continue with the Botox for your crow's feet, so the concern is really a non-tissue. I hope this is helpful. Good luck.

Dear Canada,
Crows feet Botox can have some effect on brow position and this should be evident in lateral eyelid hooding. The small difference is not likely to have a big impact on the upper eyelid excision for the blepharoplasty. However, the Botox effect is maximal at 3 weeks and by 4 months there is almost no effect left. This should have a minimal effect on your surgery.
Regarding when you should evaluate the results of surgery, almost all surgeries take much longer to heal than we think. By 10 days most bruising is resolved. By 6 to 8 weeks, most swelling has settled down but it may be 6 to 12 months to achieve what most would consider a complete healing.

The short of it is that in 4 months the botox should have minimally affected your blepharoplasty results. It is almost completely worn off and shouldnt affect the outcome.
