Patient's question:
I have had two children, both of whom have congenital preauricular fistulas. If I have more children, can congenital preauricular fistulas be prevented in advance? How can it be prevented?Doctor's answer:
A preauricular fistula is caused by incomplete fusion of the branchial clefts during embryonic development. It is generally not directly related to genetics, although hereditary cases are rare. If a fistula is present, it needs to be surgically treated to be completely cured. The surgery should be performed under the condition of no inflammation or infection.
