Eardrum is pinkish gray; see the malleus lying behind upper drum; from umbo, bright cone of light fans anteriorly and downward. Small blood vessels along handle of the malleus are normal.
Normal Eardrum
Holes in the eardrum; usually from purulent infections. Eardrum scarred; no landmarks are visible.
Perforation of the Drum

Q: What is the difference between central and marginal perforation?

Large, chalky white patch with irregular margins; deposition of hyaline material within the layers of the tympanic membrane that sometimes follows severe episodes of otitis media.

Does not usually impair hearing and is rarely clinically significant.

Air is absorbed from middle ear into the bloodstream and causes serous fluid accumulation.

Usually caused by viral upper respiratory infections.

Serous Effusion
The eustachian tube cannot equalize the air pressure in the middle ear and outside air.

S/S: Fullness and popping sensations in the ear, mild conduction hearing loss and sometimes pain.

Serous Effusion
Commonly caused by bacterial infection from S. pneumoniae or H. influenzae.

S/S: Earache, fever and hearing loss

Acute Otitis Media with Purulent Effusion
painful hemorrhagic vesicles appear on the tympanic membrane, the ear canal, or both.

S/S: Earache, blood-tinged discharge, conductive hearing loss.

Bullous Myringitits
Normal Eardrum (PIC)
Perforated Eardrum (PIC)
Tympanosclerosis (PIC)
Serous Effusion (PIC)
Acute Otitis Media with Purulent Effusion (PIC)
Bullous Myringitis (PIC)

What is the otoscope used for?

to visualize the ear canal and drum. note discharge, foreign bodies, redness.

What is the Weber test? What results do you look for?

Test for lateralization (hearing out of one ear only or better than the other)

What is the Rinne test? What results do you look for?

air conduction vs. bone conduction of sound ( can they still hear the sound waves after they stop feeling the movement of the fork?)

What is the difference between the Weber and the Rinne tests?

Weber: tuning fork is placed on top of head; do they hear equally on both sides?

Rinne: tuning fork placed on mastoid bone until they stop feeling it, then placed near ear ( cant hey still hear the fork movements?/ AC>BC)

What is a PE tube?

A PE tube (AKA tympanostomy tube) is a pressure equalization tube used to allow air into the middle ear and to drain fluid from the ear; used to decrease infections.

Name the Lymph nodes (10).

Preauricular, Posterior auricular, occipital, tonsillar, submandibular, submental, superficial cervical, posterior cervical, deep cervical chain, supraclavicular.

This node is located in front of the ear.


This node rests in the area superficial to the mastoid process.

posterior auricular

This node is located at the base of the skull posteriorly


This node is located at the angle of the mandible


This node is midway between the angle and the tip of the mandible.


This node lies in the midline a few centimeters behind the tip of the mandible


This node is superficial to the sternomastoid

Superficial cervical

This node lies along the anterior edge of the trapezius

Posterior cervical

This node is located in deep to the sternomastoid; often unpalpable

Deep Cervical Chain

This node is located deep in the angle formed by the clavicle and the sternomastoid
