  • Microtia

    Microtia is usually accompanied by aural atresia or ear canal stenosis (narrowed ear canal, no hearing change).[successforkidswithhearingloss.com] Other cases of atresia may demonstrate a small, undeveloped external ear canal which is narrower and much thinner than normal.[hear-it.org] There are four grades of microtia: Grade 1 -- smaller version of a typical ear with a smaller ear canal Grade 2 -- partially formed ear with a narrow ear canal Grade 3 --[healthyhearing.com]
