Ears Flashcards
Ask the patient to_______ from the ear being assessed.
Tip the head away
If hair obstructs visualization,_____ the speculum with water.
Moisten
Ask the patient to tip the head away from the ear being assessed.
Select a speculum that would fit comfortably the patient.
Hold the otoscope securely in the dominant hand, with the handle held like a pencil between the thumb and the forefinger.
Rest the back of the dominant hand on the right side of the patient’s head.
Use the free hand to pull the right ear in a manner that will straighten the canal.
If hair obstructs visualization, moisten the speculum with water.
Slowly insert the speculum into the canal, looking as the speculum passes.
Assess the canal for inflammation, exudates, lesions and foreign bodies.
Procedure of assessing the ears
Visualize the tympanic membrane
COLOR
PERFORATIONS
LESIONS
BULGING OR RETRACTION
DILATION OF BLOOD VESSELS
BUBBLES
FLUIDS
Note the_____ of the TM while asking the patient to pinch the nose closed and blow gently.
Movement
Normal findings of ear canal
no redness, swelling, tenderness, lesions, drainage, foreign bodies or scaly surface areas.
varies in amount, consistency and color. Cerumen is white, dry, and flaky in patients of Asian and Native American descent and honeycolored and sticky in whites and African Americans.
Normal findings of cerumen
Normal findings of Tympanic membrane
Is pearly gray with clearly defined landmarks and a distinct cone-shaped light reflex. Should move when the patient blows against resistance.
Normal findings of blood vessels
seen only in the periphery, and the membrane does not bulged, retracted or have any evidence fluid behind it.

PERFORATED TM
BLACK OR BROWN SPORES
AIR BUBBLES IN THE TYMPANIC MEMBRANE
Redness, swelling, scaling, or itching
of ear canal
OTITIS EXTERNA
deep infection of the hair follicle leading to abscess formation with accumulation of pus and necrotic tissue.
FURUNCULOSIS
“surfers ear”
EXOSTOSIS
yellowish membrane with fluid and air bubbles visible behind TM
Serous otitis
reddish TM with absent or distorted light reflex
OTITIS MEDIA
Note the red, bulging membrane; decreased or absent light reflex.
ACUTE OTITIS MEDI
blue to black TM from bleeding
HEMOTYMPANUM
round/oval dark area
Perforated TM
Greet the patient and explain the assessment.
Use a quiet room that will be free from interruptions.
Ensure adequate lighting
Place the patient in an upright sitting position.
Always compare the right and left sides of ears, nose, mouth and throat.
General approaches of hearing and equilibrium test
mainly used to establish a diagnosis in patients with unilateral hearing loss to distinguish between conductive and sensorineural hearing loss.
Test for lateralization
Weber test
a. Hold the handle of a 512 Hz tuning fork and strike the tine on the ulnar border of the palm to activate it.
b. Place the stem of the fork firmly against the middle of the patient’s forehead, on the top of the head at the midline, or on the front of the teeth.
c. Ask the patient if the sound is heard centrally or toward one side.
Weber test
Normal findings in weber test
The patient should perceive the sound equally in both ears or in the middle and there is no lateralization of sound.
The patient reports lateralization of sound to the poor ear-the client “hears” the sound in the poor ear.
The good ear is distracted by background noise, conducted air, which the poor ear has trouble hearing.
IN CONDUCTIVE HEARING LOSS
In conductive hearing loss, the poor ear receives most of the sound conducted by
Bone vibration
The client reports lateralization of sound to the good ear.
This is due to limited perception of sound due to nerve damage in the bad ear, making sound seem louder in the unaffected ear.
IN SENSORINEURAL HEARING LOSS
used to evaluate hearing loss in one ear.
differentiates sound transmitted through air conduction from those transmitted through bone conduction via the mastoid bone.
Rinne test
a. Stand behind or to the side of the patient the patient and strike the tuning fork.
b. Place the stem of the tuning fork against the patient’s right mastoid process to test bone conduction.
c. Instruct the patient to indicate if the sound is heard.
d. Ask the patient to tell you when the sound stops.
e. When the patient says the sound has stopped, move the tuning fork, with the tines facing forward, in front of the right auditory meatus, and ask the patient if the sound is still heard. Note the length of time the patient hears the sound (AIR CONDUCTION).
f. Repeat the test on the left ear.
Rinne test
Normal findings of rinne test
Air conduction is heard twice as long as bone conduction. This is noted as AC>BC or + Rinne
Bone conduction sound is heard longer than or equally as long as air conduction sound BC > AC
IN CONDUCTIVE HEARING LOSS
Air conduction sound is heard longer than bone conduction
IN SENSORINEURAL HEARING LOSS
Abnormal findings of rinne test
BC > AC = - RINNE
Occurs in conductive hearing loss, resulting from disease, obstruction or damage to the outer or middle ear.
BC> but with normal TM, patent Eustachian tube and middle ear
Most common cause of middle ear hearing loss in young adults (more common in women than in men)
Otosclerosis
HELPS TO DETERMINE WHETHER THE TYPE OF HEARING LOSS IS CONDUCTIVE OR SENSORINEURAL

IF THE SOUND LATERALIZES IN THE AFFECTED EAR
CONDUCTIVE HEARING LOSS
This is the term which is used when there are problems which the flow of ear pressure waves down the ear canal, across the ear drum or through the ossicles.
IMPACTED CERUMEN
PERFORATED CERUMEN

IF THE SOUND LATERALIZES IN THE UNAFFECTED EAR
SENSORINEURAL HEARING LOSS
