Otoscopy is one of the most widely used tests, both in otorhinolaryngology and in a primary care consultation. It is used to examine the outermost portion of the ear, from the ear to the tympanic membrane.
This is very useful, because ear pathologies, such as infections, are very common in the general population. The same goes for wax plugs or even eardrum perforations.
The advantage of otoscopy is that it is a quick, simple, and safe test. Therefore, in this article we explain how it is done, what its types are and what it can be used for.
What is an otoscopy?
Otoscopy, as we have pointed out in the introduction, is a procedure that allows the external ear and tympanic membrane to be studied. This term derives from the Greek otos which means ‘ear’ and skopein which means ‘examine’.
According to an article in Comprehensive Pediatrics, otoscopy also helps to assess the middle ear. This is because, although it does not enter said cavity, it allows us to see if there are secretions inside. It also checks if the eardrum is perforated and, if so, how is the mucosa of the middle ear.
An instrument called an otoscope is used to perform an otoscopy . It is a device that has a thickness of 2 centimeters and a disposable hollow head. The heads can be of different diameters to better adapt them to each patient.
The otoscope head has a clear lens that allows you to view the inside of the ear. In addition, it has its own light to illuminate the ear canal. The truth is that, today, there are different ways.
However, all of them have that structure more or less similar. An otoscopy may also use a microscope or endoscope. They are devices with which a more defined image is obtained.
