Can any surgeon do an endoscopic brow lift + canthopexy?

Great question!  The most important question is the experience of the surgeon.  However, surgeons who are board certified in plastic surgery or facial plastic surgery are trained to perform these procedures.  Best of luck and hope this information helps!

Like rhinoplasty and other procedures, some surgeons have mastered and specialize in these procedures. Endoscopic brow lifts and procedures to repair lower eyelid drooping are specialized procedures.  Ask your surgeon about his/her experience with these procedures. 

It depends on the surgeon's expertise and skills. The other important question is to determine if canthopexy is the correct procedure. Usually canthopexy alone doesn't lift droopy lower eyelids, if that is what you are trying to do. For best, long-lasting results, lower eyelids need to be raised using lower eyelid retraction surgery technique. See an expert oculoplastic surgeon.
