An otoscope is a medical device which is utilized to examine medical conditions of ears. Health care suppliers employ otoscopes to diagnose illness during routine medical examination and also to identify ear symptoms. An otoscope likely offers an insight vision of the ear canal and eardrum which is also known as tympanic membrane.
Since the eardrum is the perimeter parting the middle ear from the external ear canal, its attributes can be used as indicators leading to the identification of middle ear diseases.
Why is Otoscope known as Auriscope?
“Oto” means related to ears. while the scope is the study of a subject matter. When “Oto” and “scope” combines, it forms “Otoscope” which means a tool to be used in the study of examination of the ears.
Similarly, “auriform” means shape like ears, when we remove the “form” from “auriform” it will just be “Auri-” which means related to ears. Thus the combination of “Auri” and “scope” results in “Auriscope” which again means the tool or medical instrument used to study or examine the conditions of ears. Therefore both the terminologies auriscope and otoscope are used transitively as both have the same.
Doctor or nurses in healthcare facilities usually examine ears as part of their routine examination. They typically do such kind of examination when they suspect ear infection or any other problem in the ear. An otoscope empowers the doctor or nurses to examine the ear canal to view the eardrum.
An otoscope is used in otoscopy. It is an examination that involves the medical examination of the ear with an instrument. This is done so as to look into the external auditory canal. This canal is the tunnel that goes from the pinna which is the outer ear to the eardrum.
Looking through an otoscope into the ear can reveal the root cause of symptoms like hearing loss, the heavy ear feeling, and ear pain.
Sometimes hindrances can block the view of the eardrum, these hindrances can include ear wax, pus, skin fluid accumulation, particles of shed skin, the presence of the foreign body, and numerous ear illnesses. Therefore it is important that healthcare provider uses an otoscope with a superior quality and advanced features to deal with such issues.

Head: This part comprises of the magnifying lens and light bulb
