The otoscope is a standard part of many doctor’s visits. Used to examine the ears, nose, eyes, and throat, otoscopes are simple but highly versatile, diagnostic tools. Like many medical instruments, otoscopes rely on precision optical technology to function. Without custom lenses in combination with adjustable light sources, it would be nearly impossible for doctors to accurately assess problems with the ear canal or inner ear, let alone more sensitive regions like the eye.

What Is an Otoscope?

Otoscopes are medical instruments that provide light and magnification through a speculum. They are most easily recognized as the tool used to look into an ear, but they are also used during a physician’s examination of the eye and throat.

There are only two main components to an otoscope: a head and a handle. The head projects into a speculum, which is inserted gently into the canal being examined. The back of the head contains the functional optical components—namely, a magnifying lens and light—allowing the provider to get a clear view of the patient’s problem areas. The handle is used to grip and stabilize the instrument, so the provider gets a close view without damaging sensitive tissues.

The components of the otoscope’s head can be customized for specific applications aside from those seen in a generic office setting. However, a standard otoscope is designed to be convenient and cost-effective for routine visits; the lens is simple but magnifies the ear canal, tympanic membrane, and middle ear for ease of examination, and the light is bright enough to illuminate an otherwise dark region of the body. Often, the light level is adjustable to support different views. In other more specific cases, a camera extends the functionality of the device, providing a clearer view for procedures or diagnostics.

Video Otoscopes

Adding a miniature camera lens and fiber optics to the otoscope allows for a vivid, magnified view of the internal anatomy, which increases diagnostic accuracy in tricky cases. Video otoscopes also make it possible to record the exam or procedure. They are most commonly used in primary care, pediatric, and audiological settings. Specific camera types include:

  • Video Otoscopes
  • Endoscopic Cameras
  • Endocamera Systems
  • Dermatoscopes
