Abstract
A speculum body is configured to attach to the otoscope. An array of radially situated microchannels is within the speculum body and extends to apertures in a distal end of the speculum body. A power electrode array is within the speculum body positioned with respect to the microchannels to excite plasma generation within the microchannels. An optically transparent central portion is in the body to permit viewing of an eardrum by a practitioner. A method of treatment of the middle ear and/or middle ear cavity incudes actuating plasma jets to extend into the ear canal from a speculum attached to the otoscope and continuing the plasma jet treatment for a period of time sufficient to inactivate or kill a bacterial biofilm in the middle ear and/or the middle ear cavity.
