Fungal causes of otitis externa and tympanostomy tube otorrhea

Otorrhea due to fungal organisms occurs in the setting of refractory infection and is often discovered after multiple oral and ototopical antibacterial medications. Due to the extended treatment period required to clear fungal organism, timely diagnosis with culture for bacteria and fungus is required in patients with persistent otorrhea. An increase in incidence of fungal infections of the ear was found in the period after widespread use of ofloxacin began.
