What causes ear fungus?

Otomycosis is caused by direct fungal infection in most cases, which may be related to environmental factors, cerumen deficiency, long-term use of broad-spectrum antibiotics, etc.

1. Environmental factors,

environmental temperature and humidity increase, leading to changes in PH value of the external ear canal, a large number of fungi in the ear canal, invasion of the outer ear, middle ear, and then cause otomycosis.

2. Cerumen deficiency

If the external ear canal lacks cerumen protection, fungi are easy to directly invade the external ear canal, causing otomycosis.

3. Long-term use of broad-spectrum antibiotics

patients Local or systemic long-term application of broad-spectrum antibiotics will lead to imbalance of flora in the ear canal, excessive fungal reproduction will also cause otomycosis.
