Otoscopes are ear examination tools employed to look for any signs of infection or disease. These devices shine the light inside the ear canal and the magnifying lens helps see the tissues. Otoscopy is often considered a part of the primary physical examination. When it comes to using an otoscope, the first step is to learn about the otoscope parts and their respective functions.
Otoscopes are useful for ear, nose, and throat examination
In this article, let us go through the otoscope parts and learn how they play an important role in its working.
Otoscope Parts and Their Uses
An otoscope primarily has two components i.e. its head and handle. These two further have several parts that have been detailed as follows:
Otoscope Head
Otoscopes can have two types of heads. These include:
1. Diagnostic Head
A diagnostic head is employed to diagnose the problem within the ear. It can help see the ear tissues but does not allow the use of micro-instruments through the device. These diagnostic heads are fixed on the otoscopes and cannot be removed.
2. Working Head
The working head is the one that permits the healthcare provider to insert micro-instruments into the ear canal to remove small foreign objects.
In general, the head of an otoscope has 4 components of its own:
Speculum
Speculum (pl. specula) is the plastic-based tip that is attached in front of the head. It is inserted deep into the ear canal to help visualize the interior tissues. These specula can be either disposable or reusable. In the case of disposable products, these otoscope parts are for single use only and should be discarded immediately. However, the reusable specula should be wiped and cleaned after every use.
An otoscope with an attached speculum is ready for ear examination
Magnifying Lens
A magnifying lens is attached to the otoscope to increase the apparent size of the interior ear tissues. The lens can also facilitate seeing the eardrum (also known as the tympanic membrane) to find out if it is intact or has been ruptured. In general, otoscopes have a magnifying lens of 3X to 5X magnification. However, some products also come with as high as 35X magnifying power.
Light Source
Among different otoscope parts, the light source is of utmost importance. It delivers a high-intensity, bright light that illuminates the ear canal and helps see inside it. Different otoscopes have different kinds of light sources. For instance, the following are the commonly employed ones:
- Incandescent light bulbs
- Halogen bulbs
- LED bulbs
- Xenon light bulbs
Among these, the difference lies between the quality of the light source as well as the intensity it can provide. The incandescent light bulbs are cheaper in terms of cost but are short-lived as they dim over time. On the contrary, halogen light bulbs offer a brighter glow and they also last for longer.
As for the xenon bulbs, their illumination is also bright and they usually last longer than all other types of light bulbs. The LED light bulbs, on the other hand, are comparatively new and a bit expensive but have a bright whitish-blue glow. These also come with a longer lifespan.
Eyepiece/Viewing Piece
The eyepiece is one of the otoscope parts that allows viewing of the ear canal. It is through what the healthcare provider sees. The viewing piece has a funnel-like shape that is broader at one end and becomes narrower at the other. The narrow part is inserted into the ear canal for visualization.
Ear examination often gives away the cause of a health condition
Otoscope Handle
Apart from the head, the otoscope handles also have several components that are essential during an otoscopy. These are often made up of stainless steel and provide stability to the otoscope head. These include the following:
Batteries/Power Cord
Otoscopes are of two types when it comes to a power source. These can be hard-wired and are attached to the wall-mounted station with a cord. The other type i.e. the battery-powered otoscopes use AA batteries that can be charged whenever the light becomes dim. The handles of both of these otoscopes have different functions.
In the case of rechargeable battery-powered otoscopes, the handles are hollow from the inside and the space is used for fitting the batteries. As for the hard-wired otoscopes, the handle has a power cord that ensures the provision of electric current to the device.
On/Off Button
The on/off button is one of the otoscope parts that is affixed to the device handle. This is connected to the light source and helps control it.
Locking System
The locking port of an otoscope handle is the part that attaches to the head. In most cases, a single handle can receive multiple heads that can be mounted on its tip. This locking system ensures that the head does not fall or get detached from the handle.
The handles of most otoscopes are constructed using stainless steel
