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. |
Tympanosclerosis
|
|
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

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. |
preauricular |
|
This node rests in the area superficial to the mastoid process. |
posterior auricular |
|
This node is located at the base of the skull posteriorly |
Occipital |
|
This node is located at the angle of the mandible |
Tonsillar |
|
This node is midway between the angle and the tip of the mandible. |
Submandibular |
|
This node lies in the midline a few centimeters behind the tip of the mandible |
Submental |
|
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 |
Supraclavicular |
