What Are the Risks of Temporal Lift?

As illustrated in many of the other answers already given, the risks of a temporal lift are damage to a branch of the facial nerve resulting weakness or paralysis of the upper face/forehead, numbness, loss of hair along the incision line, poor scarring, infection, asymmetry, and bleeding complications. 

Indications for this type of lift are usually related to sagging of the lateral brow and/or upper cheek area of the face. If there is any associated sagging of other portions of the face, different or additional procedures should be considered. 

In your particular case I would have some real concerns about performing any surgery at all, but this is purely based on your own written assessment of your own features. I would have some real concerns about your self esteem and whether or not your expectations could be realistic. Make sure you consult with an experienced board certified plastic surgeon. 

   If you have heavy cheeks, these may need to be resuspended with a midface lift.  The temporal lift will do nothing for the cheeks.  Pictures would help.

You didn't post any pictures, but I'm pretty sure you don't look like a bulldog.  If you are referring to temporal browlift, the main risk is the risk of hairloss along the incision line, numbness or sensation changes, and injury to the frontal branch of the facial nerve.  Other procedures that could "lift" your eyes include endoscopic midface lift, blepharoplasty and canthoplasty.
