Preauricular sinus abscess, also known as preauricular sinus infection or preauricular pit infection, is a condition characterized by the inflammation and infection of a small pit or sinus located in front of the ear, near the external ear canal. This congenital condition occurs due to incomplete fusion of the embryonic hillocks during fetal development.
When a preauricular sinus becomes infected, it can lead to the formation of an abscess. An abscess is a localized collection of pus that results from the body's immune response to an infection. The infection usually occurs when bacteria enter the sinus through the opening, leading to inflammation and subsequent abscess formation.
Symptoms of a preauricular sinus abscess may include:
Pain and tenderness: The affected area may be painful and tender to touch.
Swelling: There may be swelling around the preauricular sinus, which can extend to the surrounding tissues.
Redness: The skin over the abscess may appear red and inflamed.
Discharge: Pus or fluid may drain from the sinus opening.
Fever: In some cases, individuals may develop a fever as a result of the infection.
Treatment for a preauricular sinus abscess typically involves antibiotics to control the infection. In some cases, incision and drainage of the abscess may be necessary to remove the accumulated pus. Surgical removal of the entire sinus tract may be recommended in recurrent or severe cases to prevent future infections.
It's important to consult a healthcare professional for an accurate diagnosis and appropriate treatment if you suspect a preauricular sinus abscess or any other medical condition.
