Patient's question:
My ear canal is inflamed, and it is said that I have preauricular fistula. I plan to have surgery for it. How long does the surgery for preauricular fistula take?Doctor's answer:
Congenital preauricular fistula is a common otological disease. Those without symptoms do not require treatment. If infection and suppuration occur, anti-infective treatment such as antibiotics should be administered, or abscess incision and drainage, local dressing changes, and other treatments should be performed. After the infection is controlled and the local area has healed, the fistula resection can be performed. A small amount of methylene blue is injected into the fistula before surgery, and a probe is inserted into the lumen as a guide. The fistula and its branches are then completely removed. If residual fistula tissue remains and infection recurs, further surgery should be performed for complete treatment.
