What is Otoscope?

The ear otoscope is used by an ENT specialist for examining ear. The eardrum is a border, which separates the external ear from the middle ear and the characteristics of eardrum help in indicating the diseased condition.

For examining an ear, the examiner inserts the ear speculum side into the ear canal from the external ear. It is essential to hold the otoscope over the patient’s head for avoiding damage to the ear canal. It is vital to place your little finger over the head, and the examination can be done through the lens inside the ear canal.

Medical practitioners can get the otoscopes often with an ophthalmoscope that comes as a diagnostic set. An otoscope is widely used for examining diseases like otitis media, otitis externa, and infections in outer and middle parts of the ear. Few otoscopes are even applicable for examining nasal canal and upper parts of the throat which can avoid the use of separate instruments.

The most widely used otoscopes are monocular devices which can only give a two-dimensional view of the internal parts of the ear. Other otoscopes can be used along with a binocular microscope, connected to a metal ear speculum, which helps in providing a larger field of view. It has an additional advantage of better lighting, stability and depth perception. In most of the cases, the binocular view is preferred as it helps in judging the depth.

What is a difference between an otoscope and ophthalmoscope?

ophthalmoscope

Medical professionals use otoscope and ophthalmoscope for observing the body parts to some extent only. Both the instruments are non-invasive that can be used in combination with magnifying lenses and light for observing the same. The major difference between otoscope and opthalmoscope is:

The ophthalmoscope is the instrument limited for usage by ophthalmologists for checking eyes for any disease. The instrument shines the light through pupil that helps practitioner in examining the interior parts of eyes that are referred as fundus. It helps the doctor in examining the parts which form fundus that includes optic disc, retina, and macula. This is performed as a part of the routine check-up of the eye and physical examination.

Both instruments differ in appearance, as the head of the ophthalmoscope is flat on two sides which do not come in contact with eyes. Whereas, otoscopes has a cone-shaped tip that protrudes which helps in examining patient’s ear. The tips are usually covered with speculum covers that can be used during the examination. Though they both are almost similar in shape, most of the ophthalmoscope is designed which can be worn on the physician’s head.

Otoscope Parts

Otoscope consists of three major parts, where one is the handle that contains a power for emitting light, the head which has the light bulb and a magnifying lens. The last one is the cone that is inserted into the ear canal. Otoscopes sometimes come with a handle and head that contains magnifying lens and light source. The end of otoscope has plastic ear specula which can be used for insertion and can be removed for cleaning to prevent infections.
