Pre-Auricular Sinus

A pre-auricular sinus is a small, congenital (present at birth) indentation or hole located near the front of the ear, usually just above the ear canal. This condition occurs when the tissues around the ear fail to fuse properly during fetal development, leading to a small pit or tract. Pre-auricular sinuses are generally harmless but can sometimes become infected, leading to pain, swelling, or drainage of pus. In rare cases, they can develop into an abscess or cause recurrent infections. Treatment for an infected pre-auricular sinus typically involves antibiotics, and in some cases, surgical removal of the sinus may be recommended to prevent future infections.

What is a pre-auricular sinus?

A pre-auricular sinus is a small hole or indentation located just in front of the ear, often near the ear canal. It is a congenital condition, meaning it is present at birth and results from incomplete fusion of the tissues during fetal development.

What causes a pre-auricular sinus?

A pre-auricular sinus is caused by the incomplete development of the ear during fetal growth. It occurs when the structures of the ear, particularly the folds near the ear canal, do not fully merge during development, resulting in a small pit or sinus.

Are pre-auricular sinuses common?

Yes, pre-auricular sinuses are relatively common, occurring in about 1-2% of the general population. They are more prevalent in some regions, such as in Asia, and may be inherited in families.

Can a pre-auricular sinus cause problems?

In many cases, pre-auricular sinuses don’t cause any issues. However, they can become infected, leading to pain, swelling, redness, or discharge of pus. If infected, they may require treatment with antibiotics or, in some cases, surgical removal.
