It is persistent (or at least has persisted for about 20 years), is just the one ear (because that was what was exposed), and could perhaps be differentiated from blunt trauma cases in that the swelling only affects the helix and the directionality is different. How to explain the last part? If you imagine an axis going down your ear canal, with blunt trauma the swelling is generally parallel to that axis (the ear is made thicker) while with my ear it’s along a radius perpendicular to that axis (the ear is made taller).

Thanks! Good to know.
