I do not think you tore her ear.. You surely would have seen blood.
Her hair should grow back..I have tape my babies ears that way two and it worked..Your babie might be cutting some teeth that is why one is up and one is down.I just retape them for a day and they stood right back up.
try some rolled up gauze in side the ear for support.
