According to what you said, it should not be the position of the helix foot. Maybe the location in the anatomical description is not clear. It is estimated that your disease should be that the preauricular fistula is washed with normal saline, then with hydrogen peroxide, and finally with normal saline, and gauze is packed once a day, which requires infusion treatment.

When infected, the fistula is red, swollen, painful or abscess dissolved. After inflammation, the fistula will repeatedly become inflamed, fester and fester. The lumen will also develop deeply, and a few infections can extend to the external auditory canal or mastoid process, which is easily misdiagnosed as mastoiditis. People with repeated infections may have local long-term unhealed fistulas or scars, and the patients are very painful. Don't squeeze the secretion in the fistula at ordinary times to avoid infection.
