Patient's question:
Does congenital preauricular fistula interfere with hearing? Should congenital preauricular fistula be surgically treated? What are the hazards if it is not treated after inflammation? Including hearing loss or even hearing loss and other diseases. Are there other treatments besides surgery?Doctor's answer:
Some people have a small structure in front of their ears, medically known as a preauricular fistula. It is a common congenital malformation, also referred to as a congenital fistula. It is closely related to the developmental abnormalities of the mother during the embryonic stage. It can occur on one side or both sides. Approximately 90% of the fistula openings are located in front of the helix angle. Most fistulas have branches. The wall of the fistula is composed of a layer of squamous epithelium. The lumen of the fistula contains shed epithelial cells and keratin, which can discharge.
