Question
My child has swelling and inflammation around the ear canal on the left ear. Can an infection of the preauricular fistula lead to recurrent discharge of pus?
Answer
Infection of the preauricular fistula can indeed lead to recurrent discharge of pus. When an infection occurs, incision and drainage may be necessary to remove pus. After inflammation subsides, consideration can be given to fistula closure and excision surgery. It is generally recommended to perform surgery around the ages of 6 to 9, as children in this age range have better tolerance to surgery and anesthetics.
