How low does the eyelid need to be for a brow lift? my facial nerve is paralysed and i have alight gold weight implant, but my lid droops to the pupil

Brow lift: It really depends on how low your brow is, how well you blink, if you have any corneal drying. If they raise your brow you may not have sufficient coverage of your cornea. Best determined by an oculoplastic specialist. That is an ophthalmologist who specializes in eye plastic surgery.

Contradictory goals: Your facial nerve a paralysis is the primary problem. Without the gold weight pushing down your eyelid to help, with closure, your cornea could be exposed and abraded leading to scarring. Performing a brow lift now may lead to more corneal exposure. It may be better to consider a lighter or less heavy gold weight but this cloud lead to further exposure problems. Springs may be used but problematic.

Browlift: Having a browlift may help restore symmetry due to the paralysis of cranial nerve VII. Your best option is to have your eyes evaluated by a board certified surgeon with expertise in treating patients with facial paralysis.
