Patient's question:
Congenital preauricular fistula is now inflamed with a bit of odor. Sometimes, there's a buzzing sensation in the head and ears, and I feel a bit lacking in energy. I have used topical medication and taken oral medication, but the condition sometimes improves and sometimes worsens. I have consulted a doctor and been told that surgery is necessary. So, I would like to ask how long does the surgery for congenital preauricular fistula usually take?Doctor's answer:
Congenital preauricular fistula is a common otological disease. It is caused by the poor fusion of the second and third branchial arches or incomplete separation of the second branchial groove during the embryonic period, forming small papillary nodules. The fistula can be branched and tortuous, with its external opening usually located in the anterior superior part of the helix. The lumen is lined with stratified squamous epithelium, and the squames inside the lumen can push against the fistula opening. Occasionally, some viscous sebaceous gland-like material may seep out from the fistula. Once infected, it may cause redness, swelling, and pain, and can recur repeatedly. This condition is an autosomal dominant genetic disease with incomplete penetrance. Those without symptoms do not require treatment. For infection, anti-infection treatment is needed. For abscess formation, incision and drainage are required. After healing, surgical excision of the fistula is necessary.
