Otomycosis, also known as fungal otitis externa, is a fungal infection of the outer ear canal. It is typically caused by fungi such as Aspergillus and Candida species. The condition often occurs in warm, humid environments and can be triggered by several factors, including: 1. Excessive Moisture Frequent exposure to water, such as swimming or living in humid climates, can create an environment conducive to fungal growth. 2. Trauma or Irritation _Injury to the ear canal, often from cleaning with cotton swabs or other objects, can make the skin more susceptible to fungal infection. 3. Pre-existing Ear Conditions Conditions like eczema or chronic otitis externa can increase the risk of otomycosis. 4. Immunosuppression -Individuals with weakened immune systems, such as those with diabetes or HIV, are more prone to fungal infections, including otomycosis. 5. Use of Hearing Aids or Earplugs_ Prolonged use of these devices can trap moisture and create an environment that promotes fungal growth. Symptoms of otomycosis include itching, pain, ear discharge, and a feeling of fullness in the ear. Treatment typically involves antifungal ear drops and keeping the ear dry.
