Treatment for Fungal Otitis Externa
Fungal otitis externa should be treated with topical antifungal therapy as the first line of treatment 1.
- The treatment may include debridement to remove debris and fungal elements from the ear canal, followed by the application of topical antifungal agents 1.
- Topical antifungal medications such as clotrimazole 1% solution or cream can be applied 2-3 times a day for 2-4 weeks 1.
- Alternatively, miconazole 2% solution or cream can be used with the same frequency and duration 1.
- In severe cases, or in immunocompromised patients, systemic antifungal therapy may be necessary, such as fluconazole 150-200 mg once daily for 1-2 weeks 1.
- It is essential to clean and dry the ear canal before applying any medication, and to avoid water exposure to prevent further fungal growth 1.
- Using ear drops that help dry the ear canal, such as aluminum acetate 5% solution, can aid in the treatment 1.
- If symptoms persist or worsen, it is crucial to consult a healthcare professional for further evaluation and guidance 1.

From the Research
Treatment Options for Fungal Otitis Externa
- The treatment for fungal otitis externa typically involves intense débridement and cleansing, and topical antifungals 2.
- Topical antifungals, such as clotrimazole, miconazole, bifonazole, ciclopiroxolamine, and tolnaftate, are potentially safe choices for the treatment of otomycosis, especially in patients with a perforated eardrum 2.
- Oral triazole drugs, such as itraconazole, voriconazole, and posaconazole, are effective against Candida and Aspergillus, with good penetration of bone and the central nervous system, and are essential in the treatment of patients with malignant fungal otitis externa complicated by mastoiditis and meningitis 2.
Comparison of Topical Antifungals
- Clotrimazole 1% solution has been shown to be more effective than Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream in the treatment of uncomplicated otomycosis, with a higher resolution rate (88.23% vs. 80.39%) and lower treatment failure rate (11.76% vs. 19.60%) 3.
- Sertaconazole 2% cream has been found to have comparable results with miconazole and clotrimazole in the treatment of otomycosis, with a high response rate (96.43%) and no adverse reactions observed 4.
Additional Treatment Considerations
- Thorough cleansing of the canal is essential for diagnosis and treatment, but flushing should be avoided 5.
- Acidification with a topical solution of 2 percent acetic acid combined with hydrocortisone for inflammation is effective treatment in most cases and, when used after exposure to moisture, is an excellent prophylactic 5.
- High local drug levels without systemic adverse effects can be achieved with ear drops, making them a effective treatment option for fungal otitis externa 6.
