My left ear is smaller (a little bit flat on the top) than my right one. I was wondering if it could be corrected (Photo)

The difference between both sides is due to the fact that the top of the helix of your left ear is bent a little forwards. This can only be corrected by surgery – either with a traditional method or with the minimally invasive stitch method.

You have excessive folding of the superior aspect of the external part of your ear which make your ears appear shortened. This can be corrected with surgery and I use a soft mold and head band for several weeks after surgery to insure the corrected segment remains in place. As this is an uncommon problem and recommend finding a surgeon who has treated such situation.

I can only see slight asymetry of the ears, size appears normal, left helix slightly more prominent which can be addressed surgically!bwJawed TaheryENT/Facial Pkadtic SurgeonChester,UK

Difficult to answer this question since it is not clear from the photos you have posted what your specific area of concern relates to.  If you could perhaps mark your photo with an arrow or show how you think you would like the ear to look then it might be possible to come up with a solution.
