The fistula is also known as a congenital preauricular fistula, and if there is a local discharge from the fistula, it is not clinically advisable to squeeze it because squeezing will lead to increased local infection and increased discharge. If you have an ear fistula with secretions, it is recommended that the patient can do the following treatment: 1. If there is not much secretion and there is no local redness or swelling, local disinfection can be done in this case and there is no need to deliberately apply antibiotics clinically; 2. In this case, anti-inflammatory and symptomatic treatment is needed. If there is local fluctuation, it means that an abscess has formed, and in this case it is necessary to make an incision and drainage of the abscess. If there is an infection, active anti-infection treatment is required and the formation of an abscess requires incision and treatment. For the treatment of ear fistula, surgery is clinically recommended if you want to cure it.
