Question
How can one distinguish between different types of congenital preauricular fistulas?
Answer
According to your description, a preauricular fistula is a common developmental abnormality of the ear, generally with an opening above the tragus. The fistula often secretes cheesy material and may be accompanied by itching, but it should not cause pain again. If pain recurs or there is significant swelling, it may indicate an infection, and early anti-inflammatory treatment should be sought, avoiding the temptation to squeeze it. If there is regional control weakness, significant swelling, and a palpable vibration upon pressure, surgical drainage may be necessary. For congenital preauricular fistulas, it is recommended that patients seek medical treatment early and follow the corresponding treatment as advised by the doctor. At the same time, pay attention to diet, avoiding spicy and stimulating foods to prevent exacerbation of the condition. Thank you.
