Microtia w/Aural Atresia means the outer ear and often the middle ear (ear canal, the little bones that conduct sound) did not form properly during fetal development.
I went to an ENT dr. back in 2013 b/c I thought I had a severe sinus infection. Turns out, I had laryngopharyngeal reflux, colloquially, "silent" reflux, b/c it doesn't result in chest pains, but rather acid flows up into the voice box, which was affecting my singing. 3/
