If your baby has been diagnosed with or you suspect has a small hole near their ear, here is what the evidence says.

The short answer

A preauricular pit (also called preauricular sinus) is a small hole or dimple in front of the ear, present from birth. It's a common, usually harmless birth variation affecting about 1 in 100 babies. Most never cause problems, but occasionally they can become infected, requiring antibiotics or rarely surgery. No treatment is needed unless infection occurs.

Key takeaways

  • Usually normal when: Your baby has a small hole or dimple in front of the ear that has been present since birth
  • Call your doctor if: The area around the pit becomes red, swollen, warm, or painful
  • Varies by age — see the age-by-age breakdown below
Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.

Parents everywhere have the same worry. You are doing the right thing by looking into it.

What Parents Should Know

According to AAP guidelines, a preauricular pit (also called preauricular sinus) is a small hole or dimple in front of the ear, present from birth. It's a common, usually harmless birth variation affecting about 1 in 100 babies. Most never cause problems, but occasionally they can become infected, requiring antibiotics or rarely surgery. No treatment is needed unless infection occurs. At 0-3 months, preauricular pits are noticed at birth or shortly after. They appear as a tiny opening in the skin just in front of the ear, usually near where the ear meets the face. Most are small and barely noticeable. Your pediatrician will document it during well visits. Keep the area clean during baths, but no special care is needed unless it becomes red, swollen, or drains fluid. It is generally considered normal when your baby has a small hole or dimple in front of the ear that has been present since birth. However, you should contact your pediatrician promptly if the area around the pit becomes red, swollen, warm, or painful.

Normal vs. Concerning

Usually Normal
Worth Discussing
Your baby has a small hole or dimple in front of the ear that has been present since birth
The area around the pit becomes red, swollen, warm, or painful
The area looks normal - same color as surrounding skin, not red or swollen
There is increasing drainage or pus coming from the pit
Your baby has no pain, drainage, or signs of infection
Your baby has a fever along with redness or swelling near the ear
The pit was noted by your pediatrician and documented as a benign finding
A lump or cyst appears near the preauricular pit

When to Seek Immediate Care

  • The area around the pit becomes red, swollen, warm, or painful
  • There is increasing drainage or pus coming from the pit
  • Your baby has a fever along with redness or swelling near the ear
  • A lump or cyst appears near the preauricular pit

By Age

What to expect by age

0-3 months

Preauricular pits are noticed at birth or shortly after. They appear as a tiny opening in the skin just in front of the ear, usually near where the ear meets the face. Most are small and barely noticeable. Your pediatrician will document it during well visits. Keep the area clean during baths, but no special care is needed unless it becomes red, swollen, or drains fluid.

3-12 months

Most preauricular pits remain asymptomatic throughout infancy. Occasionally, you might notice a tiny bit of white or yellowish discharge, which can be normal. However, if the area becomes red, swollen, warm, or painful, or if there's increasing drainage, this may indicate infection. Contact your pediatrician if you notice these signs - infection requires antibiotic treatment.

1-3 years

Preauricular pits that have never been problematic are unlikely to cause issues. Continue with normal hygiene. If your child develops their first infection (redness, swelling, pain, discharge), your pediatrician will prescribe antibiotics. Recurrent infections may require referral to an ENT specialist to discuss possible surgical removal of the pit and underlying tract.

3 years+

Most children with preauricular pits never have problems. If infections have occurred more than once, your doctor may recommend seeing an ENT specialist to consider surgical removal. The procedure is typically elective and done to prevent future infections. If the pit has never been infected, no treatment is needed - it's simply a harmless variation.

What to Tell Your Pediatrician

  • Describe when you first noticed has a small hole near their ear and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if you've noticed the preauricular pit for the first time and want confirmation of what it is.
  • Mention if the pit occasionally has a tiny bit of discharge but no other symptoms.
  • Bring a list of any questions or observations you want to discuss at the appointment.

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.

Adenoid Hypertrophy and Breathing

Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.

Adrenoleukodystrophy (ALD) in Babies

X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.

How to Advocate for Your Child's Needs

You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.

Agenesis of the Corpus Callosum (ACC)

Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
