A brow lift for only one side? (Photo)

It is certainly possible to do a brow lift on one side but there might be more to your asymmetry than the brow alone.  There may be orbital bone asymmetry and/or ptosis as well.

Eyebrows asymmetries can be treated with either an endoscopic brow lift or Botox.Unilateral Endoscopic Brow Lift, is a plastic surgery procedure that could permanently elevate the lower eyebrow to achieve symmetry. This result is usually permanent.Botox could lower the raised eyebrow or lower the high eyebrow in order to achieve symmetry. This treatment is temporary ( 3 to 4 months) and requires recurrent treatments to maintain the resultsPatients interested in achieving eyebrow symmetry with either Botox or brow browlift should make a consultation with a Board Certified Plastic Surgeon

Thank you for writing. Though it is not completely clear from the photographs, you might have an eyelid ptosis (drooping) on the right, in addition to a lower brow. Ptosis is a condition we occasionally see. You should have your surgeon examine this. It can be repaired, though not all plastic surgeons do this operation. 

In regards to the brow, it's possible that the unevenness is due to a more active forehead muscle (frontalis muscle) on the left side as opposed to a drooping of the right side. As Dr. Mesa below points out, Botox could be used to weaken the muscle above the left brow to lower it and improve symmetry. This may be a better choice for now than a "one-sided" browlift. 

Good luck on your rhinoplasty surgery. Very likely your surgeon has an expertise in eyelid and brow surgery as well as Botox treatments. He or she should be able to advise you.
