The cost of congenital preauricular fistula surgery is approximately $8,000, which varies by region and varies by anesthesia. A fistula is a congenital condition caused by dysplasia of the 1st and 2nd parotid arches during embryonic life and can be found as a small hole at the ear screen. When there is no inflammatory infection, the hole is asymptomatic. Once local water is introduced or repeatedly squeezed, the skin at the ear screen becomes swollen and painful, and when squeezed, a white bean-like substance is seen to spill from the fistula. When an abscess forms, the pain increases and pus and blood-like secretions may ooze out. An incision and drainage, symptomatic anti-inflammatory treatment, and oral anti-inflammatory drugs such as cefixime or amoxicillin are required. When the inflammation has completely subsided, a preauricular fistulotomy is required to remove the fistula, the fistula opening, and the blind end to avoid recurrence.
