The auricular compartment is the preauricular fistula, which is a sinus or fistula that is not well developed in the embryonic development of the human body, and usually has a small fistula hole above the front of the ear, which is called the auricular compartment. If it is not inflamed, it can be left alone for the rest of your life, that is, without treatment. If the ear canal is red and swollen, you can use alcohol to disinfect it locally, clean the fistula, and crush the fistula to get rid of the secretions. If the infection is severe, an abscess may be formed and an incision and drainage may be required to remove the preauricular fistula after the entire infection is under control.
