Posterior Helical ear pits

How common is it to have posterior helical ear pits?  My daughter has them bilateral, she is also over 99% for height(parents 5'7"& 5'11), and was hypoglycemic at birth.  Her pediatrician assures me that they are very common.  I understand that peri-auricular pits are common but the literature I have read actually states that PHeP are not common at all and can sometimes serve as a tool in recognizing certain syndromes.

We recommend that your daughter be evaluated by a medical geneticist, who is a physician that specializes in the diagnosis, treatment and prognosis of genetic disorders. A medical geneticist will perform a physical exam on your daughter as well as review the personal and family history in order to help determine if the hypoglycemia, growth, and posterior helical ear pits are suggestive of a genetic condition. As you mentioned, in some cases, posterior helical ear pits a good tool to help identify additional problems. You can find a medical geneticist at the American College of Medical Genetics website.
