A severe Stahl’s ear malformation has a much more severe bend to the superior antihelical crus. Your bend looks pretty gentle and would probably be amenable to traditional otoplasty suture techniques. You would benefit from “scapha” reduction to reduce the height of the ear, which also may improve the “roll” of the helix. Sorry for a lot of technical terms. Talk with an experienced otoplasty surgeon.
The quest for perfect symmetry is sometimes frustrating. I do see the differences that you note. There appears to be more fullness and skin over the right (your right, the eye on the left hand side of the photo) upper eyelid region. Asymmetrical incisions may have been made initially to compensate for any pre-existing asymmetry. To further provide balance to your results, further skin excision from the right upper eyelid, with a little bit more fat resection, might help provide symmetry in comparison with the left eye. Best wishes.
I'm really sorry to hear about your accident. It sounds and looks pretty bad. You do have both a jaw fracture as well as a cheek bone fracture. I would consider getting perhaps a second opinion. The jaw fracture at the very least should be repaired.
It is called a pre auricular pit. These pits are a congenital remnant from the process that was involved in the creation of your ear while you were a fetus. The pit itself likely leads into a little dead-end tunnel that is lined with the same type of cells that make up the outer skin. The lining sloughs and the material becomes periodically infected, resulting in drainage, swelling, and discomfort. Excision is what is required to try to remove the pit and tunnel. If the entirety of the tunnel is not excised, you can develop recurrent infections from any element of the tunnel still entrapped inside. The procedure is not technically difficult, but assurance that the entire tract is removed is not easy to guarantee.
You do have a slight anti helical fold in both ears. Accentuating the fold (as is typically done in a regular otoplasty) would not improve the "long" appearance of the ear. There is a lot of distance between your anti helical fold and the helical rim of the ear. The area between the anti helical fold and the rim is called the scapha. A scapha reduction would help decrease the size (surface area) of your ears to make them proportionally smaller. Slightly more reduction of the scapula could be done on the left side where the rim is more ponted to create a more rounded contour to the rim.
