Q

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.

25
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
26
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
27
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
28
Normal findings of rinne test
Air conduction is heard twice as long as bone conduction. This is noted as AC>BC or + Rinne
29
Bone conduction sound is heard longer than or equally as long as air conduction sound BC > AC
IN CONDUCTIVE HEARING LOSS
30
Air conduction sound is heard longer than bone conduction
IN SENSORINEURAL HEARING LOSS
31
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

49
Normal findings of ROMBERG'S TEST
Client maintains position without swaying or with minimal swaying.
50
Abnormal findings of ROMBERG'S TEST
If the client moves feet apart to prevent fall or starts to fall from loss of balance may indicate a VESTIBULAR disorder.
51
External Ear Structures ( INSPECTION &PALPATION)
Inspect the auricle, tragus, and lobule. Note size, shape and position.
52
Normal findings of size, shape and position of auricle, tragus, lobule
Ears are equal in size bilaterally (normally 4 to 10 cm). The auricle aligns with the corner of each eye and within a 10-degree angle of the vertical position. Earlobes may be free, attached, or soldered (tightly attached to adjacent skin with no apparent lobe).
53
Abnormal findings of size, shape and position of auricle, tragus, lobule
Ears are smaller than 4 cm or larger than 10 cm. Mal aligned or low-set ears may be seen with genitourinary disorders or chromosomal defects. Microtia Perichondritis Darwinian tubercle
54

Microtia
55
Cauliflower ear
Perichondritis
56
a benign protrusion on upper part of helix
Darwinian tubercle
57
Normal findings for inspecting the auricle, tragus& lobule for lesions, discolorations, and discharge
The skin is smooth with no lesions, lumps, or nodules. Color is consistent with facial color. Darwin’s tubercle, which is a clinically insignificant projection, may be seen on the auricle. No foreign bodies, redness, drainage, deformities, nodules, and lesions. COLOR-ear should match the flesh color of the rest of the patient's POSITION-located centrally and in proportion to the head top of the ear should pass the imaginary line from the outer canthus of the eye to the occiput. CERUMEN-moist and does not obscure the TM
58
Abnormal findings for inspecting the auricle, tragus& lobule for lesions, discolorations, and discharge
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
59
Parotitis
Inflammation of parotid glands
60
Bruising over the mastoid process
Battle's sign
61
Inflammation of mastoid process
Mastoiditis
62
Normal findings of palpating the auricle and mastoid process
Normally the auricle, tragus, and mastoid process are not tender.
63
Abnormal findings of palpating the auricle and mastoid process
A painful auricle or tragus is associated with otitis externa or a postauricular cyst. Tenderness over the mastoid process suggests mastoiditis. Tenderness behind the ear may occur with otitis media. OTITIS EXTERNA MASTOIDITIS ■ Missing or malformed landmarks: Associated with hearing deficit. ■ Creased earlobe: Associated with heart conditions. ■ Ear pits or sinuses usually located anterior to the tragus: Associated with internal ear anomalies. ■ Low-set ears or ears rotated posteriorly more than 15 degrees: Associated with mental retardation. ■ Drainage: Bloody drainage can result from trauma and purulent drainage from an infection. Clear drainage may be spinal fluid from a head injury. ■ Impacted cerumen. ■ Redness: Inflammation may indicate infection, fever. ■ Lesions: E.g., skin cancer from sun exposure.
64
Inspecting the external auditory canal
Note any discharge along with the color and consistency of cerumen (ear wax).
65
Normal findings in inspecting the external auditory canal
A small amount of odorless cerumen (ear wax) is the only discharge normally present. Cerumen may be yellow, orange, red, brown, gray, or black and soft, moist, dry, flaky, or even hard.
66
Abnormal findings in in inspecting the external auditory canal
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 (refer client to physician immediately) Impacted cerumen blocking the view of the external ear canal—conductive hearing loss
67
Normal findings in observing the color and consistency of the ear canal walls and inspect the character of any nodules.
The canal walls should be pink and smooth and without nodules.
68
Abormal findings in observing the color and consistency of the ear canal walls and inspect the character of any nodules.
Reddened, swollen canals—otitis externa Exostoses (nonmalignant nodular swellings) Polyps may block the view of the eardrum

The tympanic membrane should be pearly, gray, shiny, and translucent with no bulging or retraction. It is slightly concave, smooth and intact. A cone-shaped reflection of the otoscope light is normally seen at 5 o’clock in the right ear and at 7 o’clock in the left ear. The short process and handle of the malleus and the umbo are clearly visible.
70
Inspect the tympanic membrane (eardrum). Note color, shape, consistency, and landmarks. ABNORMAL FINDINGS
