HEALTH TALK :Baby Born With Ears Under Its Chin.

Birth defects are quite common around the world, some more than
others. Every once in a while we see one that just catches our
attention and makes us think back to whether or not we’ve seen it
before.
In this case, it appears to be a rare deformity that caused a baby
born with ears under its chin. The image, taken from the popular
photo site Imgur shows a newborn baby who was born with a few
cranial birth defects, such as a deformed mouth and jawline, but
more prominently the placement of the ears stands out.
The placement of the ears in this case is somewhat reminiscent of
where gills would be on an aquatic animal, or fish. Perhaps they
simply failed to migrate to the side of the head after they were
formed.
In the first trimester of pregnancy, the ears form along the jaw
line out of cartilage. At some point during the second trimester the
ears typically migrate to their correct place on the side of the
head.
This is the normal process that appears to have failed during the
second trimester, which resulted in the low placement of the ears as
well as the deformed jaw line. The Mayo Clinic states that by 18
weeks of gestation, a fetus should be able to hear, as well as have
fully formed ears.
