4. Folded ears
Anencephaly is closely tied with several other birth defects, including anotia and microtia. Both symptoms are visually noticeable in ultrasound and at birth. Anotia is the folding or defect that causes the visible exterior part of the ear to not develop or to underdevelop. Microtia is a type of folding defect that makes the visible ear from extra small and in a distorted fashion. Just like with Anencephaly, this symptom develops in the early weeks of gestation.
Not all forms of folded ears are easily noticeable, but in some cases, it is extremely apparent. The look of the ear is always affected, but in some cases, the actual hearing will remain intact.
Some patients who suffer from folded ears may be born with a narrow ear canal or will be messing the ear canal completely. There are 4 forms of microtia starting from 1 which is the mildest form ranging to type four which is the most severe.
