Scoping Out The Mysteries Of The Ear

The otoscope provides illuminated magnification of the inside of a patient's ear canal.

Whether you're a healthcare professional or running a veterinary practice for Fido, you use diagnostic tools to find signs of potential problems inside your patients' bodies. For example, a doctor uses a stethoscope's hollow tubing and earpieces to listen to the high-frequency sounds produced by a patient's heartbeat. But what happens when the patient's ears are the topic of concern? In much the same way as the stethoscope is a standard diagnostic tool for annual checkups, so is the otoscope when used to look inside the human and canine ear to identify and treat medical issues.

The otoscope provides illuminated magnification of the inside of a patient's ear canal. Regardless of the type used, the device is equipped with several standard components. These include: the specula, specially shaped tools for gently probing and visualizing the ear canal; the head, which consists of an eyepiece and magnifying lens; a handle, containing an integrated power switch; an internal battery, responsible for supplying power to the device; and a light source. The light with which an otoscope is equipped can take the form of halogen, xenon, LED, or even fiber optic illumination.

Otoscopes fall into three main categories: pocket, full-size, and video. As its name suggests, the pocket otoscope easily slips into a lab coat pocket, making it an ideal tool for the doctor who's always on the go. The heads of most pocket otoscopes can be unscrewed to access their light sources when the time comes to replace them. Pocket otoscopes are powered by disposable AA alkaline batteries accessible through a cap on the bottom of their handles.

Setting the full-size otoscope apart from its smaller competition is the interchangeability of both its head and handle. The interlocking tool design from medical supply company Welch Allyn has made possible the attachment of different otoscope heads to the same handle. This means that a physician has the flexibility to attach a more advanced head to the same handle, upgrading certain components of the device without having to replace it entirely. Most full-size otoscopes are powered by rechargeable batteries, which means the user can plug the device into a standard wall outlet instead of relying on a reserve of disposable batteries.

The video otoscope is the most modern of all three types. Designed to interface with a computer monitor or television screen, this device captures both high-quality images and video inside the ear, projecting an enlarged view of the tympanic membrane that includes details of all its structures. Because it can be used to document the ear canal through images and video over time, the video otoscope is useful in determining the effectiveness of clinical procedures, such as the removal of cerumen.

Diagnosing Your Options

If your career path leads you to providing hearing care in the medical world, consider all available features and options.

Size and weight are critical features to consider when investing in an otoscope. If you have particularly large hands, then a full-size or video otoscope will work quite well for your needs. They are lightweight and easy to control, which simplifies the experience of performing an examination on a young child or fussy pooch.

For example, high-quality LED bulbs last for thousands of hours with an ability to distinguish a variety of colors observed within the ear canal.

Consider the source of power for your otoscope. Some offer wireless operation and run on rechargeable batteries, while others offer wired configurations with wall-mountable power transformers.

Look for a device capable of pneumatic otoscopy. A pneumatic otoscope is equipped with an integrated port for an insufflation bulb that applies positive and negative air pressure to the eardrum. This delivery of air pressure allows you to determine how rigid or flexible a patient's eardrum is and whether that result could indicate a problem in need of treatment.

You must decide on the appropriate light source for your needs. For example, high-quality LED bulbs last for thousands of hours with an ability to distinguish a variety of colors observed within the ear canal. These colors indicate the overall health of the area under examination. That said, it's in your best interest to spend a little extra for a reliable source of illumination to ensure a proper diagnosis.

Finally, you must choose the type of specula that work best. Some doctors prefer using disposable specula, as their otoscopes have built-in ejection systems that minimize direct contact with such contaminated components prior to their disposal.

A Brief History Of The Otoscope

The earliest concept of an otoscope dates back to the year 1363. French physician and surgeon Guy De Chauliac described his invention as a tong-shaped specula device used to examine both the nasal and aural passages of the human body.

It was at this point in time that ear speculum gained international acceptance as the standard means for examining the inside of a patient's ear.

By 1838, Vienna native Ignaz Gruber developed the first funnel-shaped specula made entirely from metal. Unlike Chauliac's invention, Gruber's device had a relatively simple, conical shape that wasn't separated by a pair of jaws. While Gruber's design was never officially published, its operation was demonstrated to W.R. Wilde from Dublin, who further refined the device in 1844. It was at this point in time that ear speculum gained international acceptance as the standard means for examining the inside of a patient's ear.

The first pneumatic otoscope was invented in 1864 by German native E. Siegle. Siegle's device allowed for the examination of the eardrum as well as its response to variations in air pressure. This time period saw the incorporation of modern otoscope characteristics, including interchangeable ear specula, illumination of the ear canal using a perforated mirror, and a magnifying lens. All of these components were engineered into a single diagnostic instrument that we still know and use today.

Modern otoscope designs include advanced video and image capturing functionality along with completely wireless operation for increased freedom of movement around a doctor's office.
