Ptosis correction technique most likely to drop the eyebrows?

The degree of brow retraction reflects the degree of ptosis - the worse the ptosis, the higher the brow is likely to be to compensate for the low lid position. The technique itself won't make a difference in the post op brow position, but there will be a difference indirectly, in that a muellerectomy, levator advancement and frontalis sling are used for progressively more severe degrees of ptosis.

The technique of ptosis surgery is dependent on degree of eyelid ptosis and strength of the levator muscle responsible for lifting the eyelid. Usually, the worse ptosis, the more brow compensation.  The degree of brow compensation depends on mainly the amount of ptosis but others factors are present too.

It sounds like your brows are currently elevated to compensate for your ptosis. In that case, if the ptosis is corrected appropriately, your brows should lower to the level that they normally appear at rest such as when you are sleeping and relaxed. Some patients have had brow elevation for so long that they have an involuntarily habit of lifting their brows with facial expressions or when speaking. These patients may also need botox after the procedure to help relax the brows after their ptosis repair.

Oftentimes they will drop, but not always.  This can happen with any approach.  Compensatory pulling upward of the eyebrows occurs from droopy eyelids from too much skin or blepharoptosis.  Rarely, patients benefit from botulinum neuromodulators to help drop the brows following lid surgery when some patients have pulled upward on them for so long that they don't relax this compensation following surgery.  Hope this helps.
