What is the minimum amount of skin that can be removed in an upper eyelid surgey?

I have removed as little as a few millimeters that was causing an extra fold that was aesthetically bothersome.  The amount removed varies at different parts of the upper eyelid (e.g., inner vs middle vs outer eyelid).  It is very crucial how much is left as in many patients having less than 20-25 mm between the eyelid margin and the brow can lead to trouble with eye closure and dry eyes.  Too much removal can also cause significant brow descent that may not look good after surgery.  You need to be more concerned with finding a surgeon with good qualifications, word of mouth, and reviews.

A small slither of skin such as 4 to 6 mm can help reduce an excessive upper eyelid skin fold and look very natural. Usually the underlying muscle need not be removed if the amount is tiny. However, all surgery is risky and even removing an minimal amount of skin carries the risk of bruise, swelling, infection, redness and scar. The most common indication for a minimal skin removal is to alter the lid crease height and improve symmetry between the two eyes.Usually the question is "what is the maximum that can be removed" rather than minimum. If you are worried about a small excess upper eyelid skin fold, it may be due to relative eyebrow descent, and you should consider selective Botox to lift he eyebrows up a little and open up the eyes..
