EARS Flashcards
is a flashlight-type viewer used to visualize the eardrum and external ear canal
Otoscope
What is the equal bilateral size of the ears?
Normally 4-10 cm
Enlarged preauricular and postauricular
lymph nodes
Infection
Tophi (nontender, hard, cream-colored
nodules on the helix or antihelix, containing uric acid crystals)
Gout
Blocked sebaceous glands
postauricular cysts
Ulcerated, crusted nodules that bleed
Skin cancer (most often seen on the helix due to skin exposure)
Redness,swelling,scaling,or itching
Otitis externa
Pale blue ear color
Frostbite
which is a clinically insignificant projection, may be seen on the auricle
Darwins tubercle
A painful auricle or tragus is associated with
Otitis externa or postauricular cyst
Tenderness over the mastoid process suggests
Mastoiditis
Tenderness behind the ear may occur with
Otitis media
Colors of cerumen (earwax)
ROYBBG
Red, orange, yellow, brown,black, gray
Foul-smelling, sticky, yellow discharge
otitis externa or impacted foreign body
Bloody, purulent discharge
Otitis media with ruptured tympanic membrane
Blood or watery drainage (cerebrospinal
fluid)
Skull trauma
Impacted cerumen blocking the view
of the external ear canal
Conductive hearing loss
Abnormal findings in the ear canal may include:
• Reddened, swollen canals—otitis externa
•Exostoses(nonmalignant nodular swellings)
• Polyps may block the view of the ear drum
Red, bulging eardrum and distorted,
diminished, or absent light reflex
Acute otitis media
Yellowish, bulging membrane with
bubbles behind
Serous otitis media
Bluish or dark red color
Blood behind the eardrum from skull trauma
White spots
Scarring from infection
Perforations
Trauma from injection
Prominent landmarks
eardrum retraction from negative ear pressure resulting from an obstructed eustachian tube
