I had an arab gelding, when I was younger, who was born with sarcoids in his ears that the previous owners had tried to remove with a blow tourch. (No I'm not joking). For years I had to bridle him around his ears and work around his touchiness. He was a great youth horse, went swimming, packed trails, won ribbons, but wouldn't let you get near his ears. I figured after such a horrible experience for him it wasn't worth it for me to push him. (you should have seen me taking the cavason apart and buckleing it around his head for english classes) Quite amusing, but it kept him sane and happy.
Yes, try the regular desensitizing techniques, but your mare may have a tramatizing experience at one time, so keep in mind, if you can work around it, it might not be so bad for her to have one quirk. She seems, from your desciription, to be great otherwise. Try bridles that snap or buckle around so you don't have to put them over her head.
