Question
The right anterior auricular fistula of a two-year-old girl has been inflamed repeatedly for half a year without improvement. Antibiotics and penicillin injections have been ineffective, and there is continuous discharge of secretions. After treatment with Dalacin, granulation tissue has formed, and a solution is sought.
Answer
The anterior auricular fistula, also known as a congenital anterior auricular fistula, is commonly seen as a remnant of the first branchial cleft during embryogenesis. It usually presents without symptoms but can cause redness, swelling, pain, or formation of abscesses when infected. Treatment options include antibiotic therapy, incision and drainage, regional disinfection, and fistula excision surgery. Those without symptoms may not require treatment, while those with symptoms should seek professional medical assistance. Solution: The anterior auricular fistula, also known as congenital anterior auricular fistula, is a remnant from the first branchial cleft during embryogenesis. It often occurs unilaterally. The fistula opening is usually located in front of the earlobe, and the fistula can form branches or fork-like structures. The inner surface of the tube is lined with stratified squamous epithelium, with desquamated epithelial cells and keratinous material inside the lumen. Due to infection and decay, smelly curd-like secretions can be discharged. Generally, this condition often presents without symptoms; occasionally, there may be a small amount of mucus or purulent discharge when compressed. When infected, the area can become red, swollen, painful, or form abscesses. In cases of recurrent infection and abscess formation, scarring may occur. Generally speaking, those without symptoms do not require treatment. If there is infection and abscess formation, antibiotics or sulfonamide drugs can be administered.
