While I was informed to proceed with the treatment of a patient, I noticed a small hole near his right ear. At first, I became curious and asked him, “What happened? Did you get your ear pierced recently?”
He smiled and said, “No, it has been there since birth, and it never caused any infection.”
That moment made me curious to learn more. Later, I understood that it was a Preauricular Pit—a small congenital opening present near the front of the ear.
It is also popularly known as a “wisdom hole” or “angel hole,” often believed to symbolize rare and unique qualities. Some people even describe it as a “third ear” associated with inner wisdom. But medically, it has a developmental explanation.
What is a Preauricular Pit?
A preauricular pit is a congenital malformation of the preauricular soft tissues that develops during fetal growth due to incomplete fusion of the ear structures.
• It is commonly seen on one side (unilateral), more often on the right side, though in some individuals it may be present on both sides (bilateral).
• Most people remain unaware of it unless it is noticed during routine examination or when it becomes infected.
Clinical Importance
Usually, it appears normal and does not cause any symptoms. However, when infected, it may present with:
• Redness
• Swelling
• Pain
• Discharge or pus
Common microorganisms include:
• Staphylococcus species
• Less commonly Proteus, Streptococcus, and Peptococcus species
• In some cases, preauricular pits may also be associated with inner ear or renal anomalies and can be seen in certain syndromes.
Management
• No treatment is required if it is asymptomatic.
• If infection develops, antibiotics may be advised by the doctor.
• In case of abscess formation, drainage may be required.
• In recurrent or persistent cases, surgical excision of the sinus tract (sinectomy) may be recommended.
Have you ever noticed a small clinical finding during patient examination that made you stop, observe, and learn something new?
