"The less you have to gain, the more you have to lose". Leave it alone. You have a very acceptable result and are more likely to "lose" with each subsequent revision.
Problems with ear correction
I am sorry to hear of the trouble you have had with your ears, and the requirement to have revision surgery.Generally in plastic surgery, there is a law of diminishing returns when going back for more surgery - i.e. further surgery is less predictable, less straight forward and more risky with regards to outcome.
From what I can see in the photograph, I would suggest leaving things now, as I think the ear has a normal appearance and I would question how much improvement further surgery could make.
