Topical treatments with enilconazole and miconazole have been used with success in some cases. The presence of a diptheritic membrane (necrotic material over the surface of the fungal plaque) may prevent penetration of systemic antifungals. Additionally, there is increased risk of fatal hemorrhage due to the longer course of medical treatment. The preferred method to treat severe guttural pouch mycosis is to surgically insert a coil or balloon into the affected blood vessel to quickly cut off the blood supply (Figure 2). Typically, once the blood supply has been removed, the fungus regresses.
