From the Guidelines
Treatment for fungal sinusitis typically involves a combination of antifungal medications, surgery, and management of underlying conditions, with the goal of reducing morbidity, mortality, and improving quality of life. For invasive fungal sinusitis, urgent surgical debridement is necessary to remove infected tissue, followed by systemic antifungal therapy such as amphotericin B or voriconazole 1. The most recent and highest quality study, the european position paper on rhinosinusitis and nasal polyps 2020, recommends that treatment for invasive fungal rhinosinusitis should follow three principles: systemic antifungal therapy, surgical debridement of necrotic tissue, and reduction of immune suppression when feasible 1.
Some key points to consider in the treatment of fungal sinusitis include:
- For invasive fungal sinusitis, treatment duration is typically 3-6 months, depending on clinical response 1
- For allergic fungal sinusitis, endoscopic sinus surgery to remove fungal debris and polyps is the primary treatment, often followed by topical corticosteroids like fluticasone to reduce inflammation 1
- Fungal balls (mycetomas) usually require surgical removal without antifungal medications 1
- Controlling underlying conditions such as diabetes or immunosuppression is crucial for successful treatment 1
- Antifungal therapy targets the fungal cell membrane or inhibits ergosterol synthesis, which is essential for fungal cell wall integrity, while surgery physically removes the fungal burden that medications alone cannot effectively address 1
It's worth noting that the 2016 guidelines for the use of antifungal agents in patients with invasive fungal diseases in Taiwan recommend AmB and posaconazole as the only active agents for infections, with L-AmB often preferred over AmB-d due to its lower nephrotoxicity 1. However, the most recent and highest quality study, the european position paper on rhinosinusitis and nasal polyps 2020, provides the most up-to-date guidance on the treatment of fungal sinusitis 1.
In terms of specific treatment regimens, the use of amphotericin B (starting at 0.5-1.0 mg/kg/day IV) or voriconazole (loading dose of 6 mg/kg IV twice daily for 1 day, then 4 mg/kg IV twice daily) is recommended for invasive fungal sinusitis 1. Additionally, saline nasal irrigation (240-480 mL twice daily) can help clear residual fungi and debris. Overall, the treatment of fungal sinusitis requires a comprehensive approach that takes into account the specific type of fungal infection, the patient's underlying health status, and the need for prompt and effective treatment to reduce morbidity, mortality, and improve quality of life.

Treatment Options for Fungal Sinusitis
The treatment for fungal sinusitis varies depending on the type and severity of the disease. The main categories of fungal sinusitis include:
- Acute invasive fungal sinusitis
- Chronic invasive fungal sinusitis
- Mycetoma
- Allergic fungal sinusitis
Treatment Approaches
The following treatment approaches are used for different types of fungal sinusitis:
- Acute Invasive Fungal Sinusitis: Requires prompt antifungal therapy and extensive surgical debridement 2, 3, 4
- Chronic Invasive Fungal Sinusitis: Treated with a combination of surgical debridement and antifungal agents 2
- Mycetoma: Can usually be extirpated surgically and does not require antifungal agents 2
- Allergic Fungal Sinusitis: Treated with surgical debridement combined with corticosteroid therapy, rather than antifungal agents 2, 5
Antifungal Therapy
Antifungal therapy is an essential part of the treatment for invasive fungal sinusitis. Liposomal amphotericin B has been shown to be an effective alternative to conventional amphotericin B, with less nephrotoxicity and infusion-related acute toxicity 3. Systemic administration of antifungal agents is often used in combination with surgical debridement 6.
Surgical Debridement
Surgical debridement is a crucial part of the treatment for invasive fungal sinusitis, and is often performed in combination with antifungal therapy 2, 3, 6, 4. The goal of surgical debridement is to remove infected tissue and prevent the spread of the disease.
