PE tube: Pressure Equalizing Tube

A common surgical procedure performed in the U.S.

A small plastic or metal tube is placed in the tympanic membrane to equalize the pressure behind the eardrum and to allow for adequate drainage of any fluid within the middle ear space.

PE tubes have been shown to decrease frequency of ear infections without compromising the hearing function.


EENT: Eye, Ear, Nose and Throat

Eye: Complex organ that captures light and transforms it into impulses that the brain can interpret as images.

Ear: Consisting of three parts; the outer, middle, and inner ear. Hearing begins when sound waves interact with the middle ear, causing the ear drum to vibrate.

Nose and Throat: Nose is a dual functioning organ for the sense of smell and entry for the respiratory tract. Throat is a passageway connecting the back of the mouth to the nose and the esophagus to the trachea.


BC: Bone Conduction

Sound is heard in two different ways - air conduction and bone conduction. Air conduction are sound waves traveling from the outer ear, through the middle ear to the inner ear. Bone conduction are sound waves traveling directly through the skull to the inner ear.

The skull conducts lower frequency better than air, so a voice sounds much lower and fuller than when recorded.


AU: Both Ears OS: Left Eye

When you see an O, think of an eye since it is round.

For the A, remember “audio” which is heard through the ears.

For S, think of “south” and Left-handed boxers being dubbed southpaw.

When you see U, imagine it as a face, needing both eyes or ears.

Abbreviation hints


OM: Otitis Media

Otitis Media is any inflammation to the middle ear without reference to cause or development of a disease.

It is most common in children.

There are three main classifications of OM; Acute Otitis Media (AOM), Otitis Media with Effusion (OME), and Otitis Externa (swimmer’s ear).


EM: Emmetropia

The normal condition of perfect vision.

Parallel rays of light are all brought accurately to focus upon the retina.


XT: Exotropia

A form of eye mis-alignment which refers to eyes that turn outward. The opposite of cross-eyed.

Exotropia can occur intermittently or may be constant and identified in all age groups.

There are several different forms of exotropia; congenital, intermittent, sensory, and consecutive exotropia which can result after treatment for esotropia (cross-eyed).


EOM: Extraocular Movement

Normally the eyes move together in concert. When the left eye moves, the right eye moves in the same direction.

This coordinated movement depends on the innervation 3 cranial nerves that connect to 6 extraocular muscles around each eyeball, allowing movement in all directions.

A test evaluating the movements can indicate disorders of the eye organ system, nerve palsies, myopathies, or orbital bone fractures.


VA: Visual Acuity

Visual acuity is the sharpness, or clearness of vision.

It is a quantitive measure to identify black symbols on a white board at a standardized distance as the size of the symbols is varied. It is the most common clinical measurement for visual function.

VA of 20/20 is a person who can see detail from 20 feet away the same as a person with normal eyesight at 20 feet away.

VA of 20/40 is a person who can see detail from 20 feet away the same as a person with normal eyesight at 40 feet away.

It is possible to have 20/10 VA (the maximum acuity for the human eye). In comparison, hawks have a VA of 20/2.
