A photosensitizing composition for use in the treatment of otitis externa is described. The photosensitizing contains methylene blue and/or toluidine blue and is used by applying the composition to a treatment site located within the ear cavity where microbes causing otitis externa are located, inserting at least a portion of a light delivery device into the nasal cavity and applying light to the treatment site at a wavelength range from 600 nm to 680 nm to inhibit or eliminate the microbes without causing physiological damage to the host tissue within the ear cavity. The light delivery device is in light communication with a light source via a waveguide. |
