When patients need to visit doctors due to illness or for a checkup, it is quite often that an otoscope will be used. These are the devices which examine the ear for signs of any health problems, and also to help diagnose current illnesses. Otoscopes are also commonly used when patients are suspected of having an ear infection, a fever, or be suffering from hearing loss. Should there be an infection, usually the tell tale sign is the eardrum being red and swollen, or on some occasions evidence of fluids.

Otoscopes themselves are very standard in their design, consisting of a handle and also a head. The head of the otoscope holds the light source used to illuminate the inner area of the ear, and also a low power magnifying lens which allows the examiner to see into the ear and make a diagnosis.

Attached to the otoscope are speculars which are used to examine the inner area of the ear, and these are disposable after use on each patient, to ensure hygiene standards are maintained and diseases or germs are not spread. These speculars are also available in a variety of sizes, to suit the age of the patient being treated. Smaller speculars for example will be used to examine children.

There are various types of otoscopes, and these are:

- Battery Operated Otoscopes
Otoscopes which are powered by batteries are great for mobility, and doctors which visit patients away from their surgery or place of practice.

- Wall Mounted Otoscopes
Ideal for surgeries and hospitals are wall mounted otoscopes. These can be used for hours without worry on battery charge, as they are powered by an AC adaptor. Although these can be used without charging, they do not offer the level of mobility a battery operated version does.

- Video Otoscopes
As the name suggests, video otoscopes are designed to provide a recording of the inner ear area, and also to accurately monitor the eardrum. The video is displayed on an output screen which can equally be viewed by both patient and doctor. Images from the video can also be printed off for further analysis should this be required.

If you are purchasing any otoscope for home use, it is a good idea you read up on how to use one correctly, and ensure you fully understand what you are examining for too. Incorrect use of an otoscope can cause discomfort and pain to those being examined, and you could potentially risk damaging the ear drum should you push it too far. When you have your otoscopy kit, make sure you read the manufacturers guidelines and follow them during your first use. Do not push the otoscope all the way into the ear, instead slowly view the magnifying lens to see the contents and determine whether the device has been inserted far enough.

If you are unsure on how to use an otoscope, it is usually a good idea to leave this to a certified doctor or nurse, as they will have the necessary experience to help.
