My son has tiny holes on outside of both ears, when he was born, the Dr got an x-ray to make sure his kidneys were fine. Since then no one has said anything about the holes. I asked our pediatrician and she said as long as they don t get infected. Should I be worried, sometimes a substance does come out, but it s not frequent.
Preauricular ear pits, or holes are defects in the outer ear during fetal development, most of them are about 1 inch depth, and sometimes they are connected to sinuses.  It's important to exclude any other anomalies that the child may have, whicChatDoctormonly is abnormality of the kidneys, that's why a renal ultrasound is done in the newborn period. If these pits have discharge it may indicate an infection, so the use of topical antibiotics is warranted, if there is fever then your child must be checked at his pediatrician. I hope this answers your question
