What are the causes of external auditory canal mycosis?

summary

External auditory canal mycosis is a kind of opportunistic pathogenic fungus that invades the external auditory canal or in the external auditory canal. It propagates under suitable conditions and causes subacute or chronic inflammatory lesions of the external auditory canal, often accompanied by bacterial infection. Fungal infection of external auditory canal can be asymptomatic sometimes. The common symptoms are discomfort of external auditory canal, distending pain or itching, obstruction of external auditory canal, etc. Secretion smear and fungal culture can help to determine the type of pathogenic bacteria. If necessary, biopsies should be performed to help differential diagnosis and treatment. So, what are the causes of external auditory canal mycosis? Now let's talk about it.

What are the causes of external auditory canal mycosis?

External auditory canal fungi like to grow and reproduce in a warm and humid environment. When the external auditory canal is flooded or secretions are actively stored, and antibiotics are often used, they are more susceptible to fungal infection, such as penicillin, Aspergillus and Candida albicans.

Otitis externa is acute or chronic inflammation of external auditory canal skin; Fungal infection is called external auditory canal mycosis. Patients with fungal otitis externa feel itching and burning in the ear. They feel pain in the ear when they move in the temporomandibular joint. At first, the secretion is thin serous secretion, and then gradually sticky. The external auditory canal of patients with fungal otitis externa has cyan, black or yellow white moldy moss.

In the treatment of external auditory canal fungi, the first step is to remove all crusts and secretions in the external auditory canal, and apply 1-2% salicin alcohol or 1-2% thymol alcohol and 1:1000 Bromogeramine alcohol to the ear. Nystatin can also be sprayed on the external auditory canal or coated with dakining cream. Try to keep the external auditory canal dry.
