If you’ve noticed a tiny hole, dimple, or pinpoint opening in the skin just in front of your ear, it may be a preauricular pit. This is a small congenital opening that forms during development before birth. Many preauricular pits never cause symptoms and may go unnoticed for years.
The appearance alone isn’t enough to confirm what a spot near the ear represents, however. A dermatologist or other qualified clinician can examine the area, especially if the opening is new to you, becomes painful, swells, or starts draining.
Quick answer
- A preauricular pit is a small opening in the skin near the front of the ear that is typically present from birth.
- The opening may connect to a narrow sinus tract beneath the skin.
- Many pits remain quiet and don’t require treatment.
- Redness, tenderness, swelling, or drainage can be signs that the area needs medical evaluation.
- Repeated problems may lead a clinician to discuss additional treatment options.
What is a preauricular pit?
A preauricular pit, sometimes called a preauricular sinus or ear pit, is a tiny opening that usually appears near the point where the upper ear meets the face. It develops before birth as the structures that eventually form the external ear come together.
The visible pit can be only the entrance to a narrow tract underneath the skin. The depth and direction of that tract can vary from person to person. In many people, it causes no discomfort or other noticeable problems.
Why does the small hole form?
Preauricular pits are developmental rather than something caused by skincare habits, ear cleaning, acne, or wearing earrings. Some people may have a family tendency toward them. A pit can occur on one side or both sides.
Most isolated pits are simply an anatomical variation. Less commonly, preauricular pits can occur along with other congenital findings, which is one reason clinicians may ask about hearing, family history, or other symptoms when evaluating them.
Can a preauricular pit become irritated or infected?
Because a preauricular pit can connect to a tract beneath the skin, material may occasionally collect inside it. If inflammation or infection develops, the area may become red, sore, swollen, or warm. Drainage can also occur.
If you develop these changes, it’s worth getting checked rather than trying to squeeze, probe, or drain the opening yourself. A clinician can determine whether infection or another condition is responsible and discuss appropriate care.
What can you do at home?
If the pit is comfortable and unchanged, aggressive care is generally unnecessary. Simple measures can help avoid unnecessary irritation:
- Keep the surrounding skin gently clean during your normal washing routine.
- Avoid inserting cotton swabs, pins, tweezers, or other objects into the opening.
- Don’t repeatedly squeeze the pit in an attempt to remove material.
- Pay attention to new redness, tenderness, swelling, bleeding, or drainage.
If the area is actively painful, swollen, or draining, home care isn’t a substitute for an examination.
What professional options are available?
A clinician will usually begin by examining the location and appearance of the opening and asking whether you’ve had pain, swelling, drainage, or previous episodes in the same area. If infection is suspected, treatment depends on the findings and may involve medications or drainage performed by an appropriate medical professional.
For pits that repeatedly become inflamed or infected, a clinician may discuss referral for removal of the underlying sinus tract. This is generally considered based on the individual’s history rather than simply because a painless pit is present.
When should you see a dermatologist?
Consider scheduling an evaluation if you’re unsure whether the opening is truly a preauricular pit or if you notice a meaningful change. Seek medical attention for symptoms such as:
- Increasing redness or swelling
- Pain or significant tenderness
- Pus-like or persistent drainage
- Bleeding from the area
- A growing lump near the pit
- Repeated episodes of inflammation in the same location
- Fever or feeling unwell along with worsening local symptoms
A dermatologist can evaluate the skin around the opening and help determine whether additional assessment, treatment, or referral is appropriate.
Frequently asked questions
Is a preauricular pit the same thing as a piercing hole?
No. A preauricular pit typically develops before birth, while a piercing creates an opening through the skin later in life. Their locations and underlying structures can also differ.
Can a preauricular pit suddenly appear in adulthood?
A true congenital preauricular pit is present from birth, but some people don’t notice it until much later. If you believe an opening has genuinely developed recently, a clinician can examine it to rule out other causes.
Should I squeeze material out of an ear pit?
It’s better not to repeatedly squeeze or probe the opening. Manipulation can irritate the area, and swelling or drainage should be evaluated if it persists or is accompanied by pain or redness.
Does every preauricular pit need to be removed?
No. Many remain asymptomatic and don’t require intervention. Recurrent inflammation or infection is one reason a clinician might discuss further treatment or referral.
Who should evaluate an irritated preauricular pit?
A dermatologist can assess skin changes around the pit and determine whether additional care is needed. Depending on the findings and whether there have been recurrent problems, another specialist such as an ear, nose, and throat physician may also become involved.
