In some cases, there is a total absence of the ear canal or a significantly narrow ear canal. Often the ethnic background contributes to microtia among newborns.

It is categorized into four stages according to their severity and challenges.

  1. The first-grade microtia demands minor changes in the form or shape of the outer ear. The ear appears smaller than normal. But the good part is that the other vital functions of a normal ear are there.
  2. The grade-two microtia also referred to as conchal type microtia highlight a narrow ear canal. This condition is called canal stenosis. An individual suffering from grade-two microtia suffers from missing out on some features of ears but the lower 2/3rd is intact.
  3. Grade three is the most common form of microtia that newborns suffer from. The only remaining portion is the peanut-shaped small portion of the ear lobe. It is in this stage that the ear canal is also missing completely. This stage is also referred to as lobular type microtia.
  4. In the last stage, the external ear is completely missing. Also referred to as anotia, this is the most severe case , and is rarely found among patients.
