Otoscope
Modern Otoscopes for the medical examination of the ear drums and ear canals. Otoscopes like the LED otoscope are available in different colours and variations. Additional accessories, e.g. ear specula or funnels are also available in different versions.Read on here at the end of this page.
Using an Otoscope: Examining the Hearing Aid
The otoscope is used as a diagnostic instrument for examining the ear canal. A built-in light source in the otoscope, typically a halogen or LED lamp, illuminates the ear canal up to the eardrum. Through a viewing window with a magnifying function, ENT specialists or otolaryngologists can make precise observations and obtain reliable examination results and diagnoses.
This diagnostic technique, also known as otoscopy, is used to detect conditions such as inflammation, injuries, foreign bodies, or parasites. In addition to ENT specialists, pediatricians, and general practitioners, veterinarians also frequently use the convenient otoscope.
The light source is powered by batteries (battery handle) or rechargeable batteries (charging handle) located in the otoscope's handle. Modern otoscopes usually have interchangeable heads, allowing various light sources or different-sized ear funnels to be used with the same charged handle. This avoids the need to charge multiple otoscopes simultaneously, making them more cost-effective for practices.
To illuminate the ear gently and deeply, otoscopes are equipped with specialized ear funnels. These funnels adapt to the shape of the slightly curved ear canal and even straighten it slightly to obtain better examination results. You can order single-use ear funnels for your otoscope in various sizes here in the online shop.
Note: When purchasing ear funnels, make sure they are compatible with your otoscope. Pay attention to the respective millimeter measurements of the disposable ear funnels.
Otoscopes are optotechnical diagnostic instruments that combine high-quality optics with advanced lighting technology and can be used in various fields, from general medicine to ENT diagnostics. The examination method using an ear mirror is known as otoscopy.
Before purchasing an otoscope here in the online shop, you should choose one of the two common variants with different lighting methods.
- Otoscope with direct illumination: Built-in LEDs or bulbs serve as the light source in the headpiece. The lamps can be replaced, but they may slightly restrict the view during illumination.
- Otoscope with indirect illumination: In this variant, the light source is replaced by a fiber optic cable with bright light sources (LED or halogen). This allows the hearing aid to be inspected with the ear mirror without any restriction of the view.
Otoscopes are also available in a compact format as pocket otoscopes. These small ear mirrors fit comfortably in a jacket pocket or can be carried in a doctor's bag for house calls.

Modern Otoscopy with Video Otoscope
Medical optotechnology is constantly advancing. Nowadays, ENT specialists have access to modern video otoscopes equipped with CCD cameras and cold light sources. The camera in the video otoscope allows direct transmission of examination results to a monitor. The image can be magnified for more precise diagnostics. Recorded video footage can be saved and archived on a computer.
The video otoscope also facilitates the process of otoscopy for doctors, as they no longer need to lean over the diagnostic instrument to look through the otoscope's viewing window. As users, they can stand upright next to the patients and view the ear canal up to the eardrum on the screen.
Pneumatic Testing with the Otoscope
Luxamed Otoscope Blower including Hose
The so-called pneumatic testing can be used to apply otoscopy to test the movement level of the eardrum. For this purpose, the otoscope is equipped with a blower that is connected to a pump ball via a hose. ENT specialists can deliver precise air bursts into the ear canal, which in turn cause a pressure change on the eardrum and set it in motion.
Pneumatic otoscopy can, for example, indicate fluid accumulation behind the eardrum or inflammation in the middle ear. You can order otoscopes equipped with headpieces with hose and blower for pneumatic testing at affordable prices directly here in the shop.
The History of the Otoscope
Otoscopes were already used in the 19th century to examine the ear canal and the eardrum. They were invented by the French physician Jean-Pierre Bonnafont. Prior to that, the examination of the ear canal could only be done with a concave mirror. This mirror had to be illuminated by an external light source to direct the light onto the desired area. While this made examination possible, the diagnostics were generally insufficient.
Bonnafont's invention was widely popularized as an otoscope by the ENT specialist Anton Friedrich von Tröltsch and largely replaced the concave mirror. However, the modern devices have only inherited the ear funnels, also known as tips, from their predecessors. For hygiene reasons, these are often disposable plastic funnels. However, reusable tips made of plastic or metal, intended for sterilization, are also common.
In addition to otoscopes in various variations, with different interchangeable headpieces or including a carrying case, you can also purchase a wide range of other diagnostic instruments at affordable prices here in the online shop.
