Anterior ear fistulas are incised and drained without stitches to facilitate the placement of drainage strips to thoroughly drain the pus from the inside. Pre-auricular fistulas are a relatively common congenital malformation that can be asymptomatic, but when there is an increase in secretion from the fistula, a small amount of white, sticky secretion may overflow from the opening of the tube. When the fistula becomes infected and suppurates, an abscess may form if the infection is not controlled in time, and incision and drainage is needed. In general, incision and drainage is after local skin disinfection, the abscess is cut, the lower edge of the incision reaches the lowest point of the pus cavity, rinsed out and placed on the drainage strip, at this time do not need to be sutured. The incision is made after the skin is sterilized, and the lower edge of the incision reaches the lowest point of the abscess cavity. After the infection of the fistula in front of the ear, it is recommended that the patient consult a doctor in time, and actively cooperate with the doctor to carry out standardized treatment.
