In order to make such a diagnosis, the most important tool is an Otoscope

Otoscopes are also commonly used to examine patients' noses (without the use of a separate nasal speculum) and upper throats (with the speculum removed). Otitis media and otitis externa, infections of the middle and outside regions of the ear, are two diseases that can be detected with an otoscope. Monocular otoscopes are the most widely utilised in emergency rooms, paediatric offices, general practise, and by internists.

Depending on what is within the ear canal and its status, they only provide a two-dimensional picture of the ear canal, its contents, and usually at least a section of the eardrum. The use of a binocular microscope in conjunction with a larger plastic or metal ear speculum, with the patient supine and the head tilted, is another method of performing Otoscope (visualisation of the ear), which provides a much larger field of view and the added benefits of a stable head, far superior lighting, and, most importantly, depth perception. To assess depth, you'll need a binocular (two-eyed) perspective.
