  There are many kinds of pathogenic fungi, such as Aspergillus, Penicillium and Candida. Swimming, shower, middle ear purulent discharge, ear digging injury and so on are all induced influencing factors.

  Fungal diseases of the external auditory canal are characterized by early ear itching, suffocation, and a small amount of water secretion.

  It has been a long time since the epidermal cells of the external auditory canal fell off, forming a scab with the mycelium. When the external auditory canal is blocked or covered on the surface of the eardrum, the hearing ability of students may decline and tinnitus may occur.

  If accompanied by different bacterial infections, it can cause swelling and pain in the external auditory canal.

  We check the external auditory canal of the patient. The deep part of the external auditory canal is usually white, gray and yellow or smoke black musty moss, such as film, sometimes tubular or blocky.

  Put the sample on a glass sheet, add a little 10% potassium hydroxide solution and heat it properly. Put it under a microscope to see mycelia or spores, and then the diagnosis is clear.

  Generally, the external auditory canal can be treated by dropping a little 3% salicylic acid alcohol solution into the external auditory canal, or smearing the external auditory canal with a cotton swab dipped in a little dactyline cream or clotrimazole ointment.

  Prevention of fungal disease of external auditory canal

  The following measures can be taken

  1. Don't be sarcastic

  Frequent ear digging may artificially bring fungi into the external auditory canal, and earwax has a certain antibacterial effect. It is often cleaned up, which also makes the ear canal lose a safety barrier.

  2. Keep the inner ear dry and the external ear canal dry

  It can not provide soil for the growth of moist fungi.

  If there is clear water in the external auditory canal when swimming, you can lean your head towards the water entering ear and face the ground, and jump with one foot on the same side to make the water in the ear flow out in the vibration.

  3. Do not abuse antibiotics

  Long term use of antibiotics in the external auditory canal is also prone to fungal infection.

  Both bacteria and fungi have antagonistic effects. If more antibiotics are used, bacteria will be inhibited and fungi will multiply.

  Therefore, no obvious signs of bacterial infection, no doctor's guidance, do not abuse antibiotics.
