An ear, nose, and throat doctor, or ENT, is not the only one who can benefit from possessing a diagnostic otoscope. With an otoscope in your safety equipment you can make an important impact on your family's health. If your loved one tends to develop auricle pain on a regular basis, having an auriscope in your medicine cabinet will help you to determine if a physician visit is required.

What kind of otoscope should you buy?

If you're an actual ENT doctor, you will likely want to purchase a diagnostic otoscope kit with an ophthalmoscope and an insufflator for pneumatic otoscopy. If you're a parent trying to gauge the seriousness of a pre-verbal child's ear pain, then less expensive options are available to meet your unique needs. Here are some shopping features to consider:

  • Optics - Look for a unit that uses halogen lighting and fiber-optic technology for unhindered diagnostic observation of the ear canal.
  • Specula - You can buy ones with either disposable specula or reusable specula. If you don't mind sterilizing it yourself, the latter could be a better choice.
  • Batteries - You can find this equipment in styles that use disposable batteries and styles that are rechargeable. In addition to your preference on type of battery, be aware that a pocket otoscope will need less battery power than a larger one carried in a case.
  • Magnification - Standard magnification is 2.5x to 3x. Some models, like the Welch Allyn MacroView, have been developed to provide even easier viewing.
  • Case - Decide if you can get by with a zippered leatherette shell case or would need the added protection of a hard case.
What options do different brands offer?

Is an auriscope easy to use?

Practice using the instrument on healthy auricles first in order to gain experience viewing normal colors, textures, and shapes. Then, when using it for diagnostics, you'll be able to notice when cerumen or fluid builds up in the auricle or when tissues become inflamed. Product details should include positioning descriptions and instructions.
