Permanent solution to uneven eyebrows? Does this surgery require general anesthetic?

Yes surgery can help asymmetric brow heights.  However your asymmetry can be dues no many factors (differences in bone support below, differences in volume of brow tissue, etc).  If these are not addressed the result will most likely regress over time.  Please see a specialist before proceeding and get all your questions answered.BestDr. Massry

A browlift can be performed under either IV sedation or general anesthesia. For a complete unilateral browlift, I would not recommend local anesthesia but either IV sedation or general can provide a comfortable experience for the vast majority of patients. With regard to whether a one sided browlift would create the results that you seek permanently, you will need to seek an in person consultation.Stephen Weber MD, FACS Denver Facial Plastic Surgeon

Thank you for your
question. Pictures would be helpful to make sure that it is not a skeletal problem with the position of your orbits.Yes, a brow lift on one side can be easily performed and is often performed in individuals recovering from Bell's Palsy.

To be sure what is best for you, see
two or more board-certified plastic surgeons in your area for a full and
complete evaluation to make sure you are a good candidate and that it is safe
for you to have surgery.

I hope this helps.
