On the basis of a postulated schema of the pathophysiology of allergic fungal sinusitis (AFS), a variety of treatment plans addressing its multiple contributing factors has emerged. Medical control of the disease has made use of various combinations of antifungal medications, corticosteroids, and immunotherapy, with varying degrees of disease control. Attempts to control this disease by only partially addressing the underlying causes likely have contributed to a high rate of recidivism. Successful treatment of allergic fungal sinusitis (AFS) requires that the treatment plan account for each factor responsible for the propagation of the disease.

The allergic fungal sinusitis (AFS) cycle suggests that atopy, continuous antigenic exposure, and inflammation all have key roles in the perpetuation of the disease. In theory, individually accounting for each of these factors provides for the best chance of long-term disease control. This comprehensive approach to management depends on complete removal of all fungal mucin (usually requiring surgery) and long-term prevention of recurrence through either immunomodulation (immunotherapy and/or corticosteroids) or fungistatic antimicrobials.
