An otoscope is a medical device that is used to examine the inside of an ear. Doctors use otoscopes to check for illnesses or ear symptoms during regular exams. An otoscope provides a view of the ear canal and eardrum. Since the eardrum is the boundary between the external auditory canal and the middle ear, its properties can indicate various diseases of the middle ear space. The occurrence of wax, flaky skin, pus, skin edema in the canal, foreign bodies and various ear diseases can impair the view of the eardrum and thus significantly impair the value of otoscopy performed with a conventional otoscope.
