Question
In July 1996, I had an infection and felt a headache on one side of my head. At that time, I underwent drainage, and later, following the doctor’s advice, I had a congenital preauricular fistula excision surgery at the Second People’s Hospital of Sichuan Province in winter 1997.
Answer
Congenital preauricular fistula is a remnant from the incomplete fusion of the first and second arches during the development of the auricle. Treatment primarily involves surgical excision, and for those without symptoms, no treatment may be necessary. Your current condition is the formation of periauricular abscess, which should be treated first with incision and drainage. After the inflammation is resolved, proceed with fistula excision surgery. Postoperative application of antibiotics is recommended to prevent infection. The complete excision of the fistula is considered the only effective treatment method.
