Guide to learn about hearing examination and otoscopes

January 23, 2023 equimed 87

Otoscopes are essential medical devices for auditory examination, that essential medical procedure to assess hearing function and detect pathologies in the ear.

It is a safe and non-invasive procedure used to determine a person’s hearing level and detect any problems in the ear.

In this sense, there are several tests and pathologies of the auditory examination, each one with a specific focus on the evaluation of the auditory function.

One of the most common tests is audiometry, which measures a person’s ability to hear sounds of different pitches and volumes.

Impedance testing is another test used to assess eardrum function and the ear’s ability to transmit sounds. Tympanometry is a procedure that uses a small device to measure the mobility of the eardrum.

And finally, otoscopy is a basic examination that uses the otoscope so that the doctor can examine the patient’s ear efficiently.

In this article we are going to learn more about what otoscopes are, as well as their features, the types that exist and which one to choose .

What is an otoscope

An otoscope is a light beam medical instrument used to examine the ear. That is to say: a device that helps to visualize and examine the condition of the ear canal and eardrum.

Through this examination, we can find out the cause of some symptoms such as pain, a feeling of fullness in the ear or hearing loss.

It is a device widely used by general practitioners and otolaryngologists.

There are different types of otoscopes, each with specific characteristics and used in different clinical situations.

Types of otoscopes and their characteristics

With this device, the different structures of the auditory system and in particular the external canal of the eardrum are analyzed. Now, there are different types of otoscopes:

1. Halogen otoscopes
They are the most common. In the halogen otoscope, the bulb is in the head and focuses the light directly into the canal. It features a variety of interchangeable inspection tips. The otoscope’s lens allows the inside of the ear to be seen, while the light illuminates the area so the doctor can see any problems.

2. Fiber optic otoscopes
These are similar to halogen otoscopes, but have a mechanism that automatically adjusts the illumination according to the darkness of the ear canal. This helps minimize eye strain and improve exam accuracy. Also, your field of vision is completely clear and the lighting is excellent, with no shadows or reflections. The light source is located in the handle and not in the head.

3. Video otoscopes
These are the most advanced and are used to provide a real-time image of the ear with great efficiency. These instruments include a camera and monitor to allow better visualization of the ear canal. This is especially useful in cases where a detailed evaluation of the ear is required, such as when there are infections or injuries. By having a large HD screen, the field of vision is increased in addition to offering additional comfort at the visual level. Some even allow you to record the viewing.

4. LED Otoscope
In them the power of the light is much higher since it is of the LED type. They also guarantee low consumption, great autonomy, and it is not necessary to charge the battery frequently.

Medical advances in otoscopes

As for medical advances in otoscopes, the development of video and LED lighting technologies have enabled otoscopes to provide sharper and more detailed images of the ear.

In addition, wireless and smartphone-connected otoscopes have entered the healthcare sector with great force, allowing physicians to share images with other healthcare professionals and track patient visits. This helps improve collaboration between clinicians and increases diagnostic accuracy.

Technological advances have also enabled the development of digital otoscopes, which use image sensors to capture images of the ear and store them in a database for later review. This is especially useful for following a patient’s progress over time and detecting any changes in ear health.

Finally, the introduction of fiberoptic otoscopes, which use a fiberoptic light beam to illuminate the ear, allow for a safer and more efficient procedure than traditional otoscopes, since they do not emit heat and do not require an external power source.

Equimed otoscopes

At Equimed we distribute medical equipment and its consumables, betting on cutting-edge technology from the leading brands in the medical, clinical and surgical sector. And otoscopes are no exception.

As we said, examining the structure of the ears is a temporary but critical part of the physical examination. That’s why we’ve listened to countless providers and redesigned our otoscopes to improve examinations.

In this way, we have two of the most advanced otoscopes on the market: the MacroView Plus otoscope and the 3.5V diagnostic otoscope.

MacroView Plus Otoscope

The new MacroView Plus otoscope features bright, long-lasting white LED technology , maintaining illumination for the duration of one battery charge without changing color when dimmed.

Redesigned with a familiar shape and feel, with a viewing area 3 times larger compared to the view of a standard otoscope, its features include:

LumiView Clear: With our new Welch Allyn LumiView Clear single use clear optical specula, we can enjoy views up to 8 times brighter than those seen through a black ear specula.

Switch from optical to digital: By adding the Welch Allyn Examiner SmartBracket we can transform an optical examination to digital, thanks to the possibility of capturing photos and videos.

3.5V diagnostic otoscope

This high-quality traditional otoscope , with a variety of illumination options, features HPX halogen illumination and fiber optics at the distal end for easy examination. Of its characteristics we highlight:

Fiber Optic: Projects cool light to the distal tip, without reflections or obstructions, for optimal visualization of the tympanic membrane.
Wide angle lens: Allows instrumentation under optical magnification. It is available with a SureColor LED or HPX halogen (high pressure xenon) bulb.
Sealed system: For pneumatic otoscopy and the diagnosis of otitis media.

Hearing examination is an essential medical procedure to assess hearing function and detect pathologies in the ear. To carry it out successfully, otoscopes are crucial and have undergone significant advances in terms of technology and connectivity . These advances have allowed for better precision in the diagnosis and treatment of ear pathologies and greater efficiency in medical practice.
