The distal (front) end of the otoscope has an attachment for disposable plastic ear specula. These include, the otoscope, thermometer, stethoscope, penlight, sphygmomanometer, bladder scanner, speculum, and eye charts. An otoscope potentially gives a view of the ear canal and tympanic membrane or eardrum. The pneumatic otoscope is the standard tool used in diagnosing otitis media. Complete ear canal inspection requires the use of an otoscope by a veterinarian.
