Ear is divided by 3 parts

external ear, middle ear, internal ear

The external ear is divided into

auricle, external auditory canal, tympanic membrane

separates the external ear from the middle ear

tympanic membrane

collect sound waves and directs them toward the auditory meatus

auricle

Direct sound waves to the tympanic membrane

external auditory meatus

protects the middle ear and conduct sound vibrations from the external ear to the ossicles

tympanic membrane

Middle ear

ossicles, oval and round window, eustachian tube

what are the three small bones of the ossicles

malleus, incus, stapes

mechanically transmit sound waves from the tympanic membrane through the oval window to the inner ear

ossicles

opening in the inner ear from which sound vibration exit

round window

opening in the inner ear into which sound vibrations enter

oval window

in lined with mucous membrane that provides air passage from the nasopharynx to the middle ear

eustachian tube

air-filled spaces that aid the middle ear in adjusting to changes in pressure

mastoid bone

contains the sense organs for hearing and balance which form the eight cranial nerves (acoustic and vestibulocochlear nerve)

inner ear or labyrinth

rigid capsule which surrounds and protects the membranous labyrinth

bony labyrinth

connects the cochlea to the 3 semicircular canals, function in the sense of balance

vestibule

contains auditory receptors which functions in hearing

cochlea

function in the sense of balance

semicircular canal

contains receptor cells for hearing

membranous labyrinth

membranous labyrinth is composed of blank

utricle and saccule, organ of corti, semicircular canal

organ of static equilibrium

utricle and saccule

the end organ of hearing

organ of corti

function in dynamic equilibrium

semicircular canal

a gradual sensorineural loss caused by nerve degeneration in the inner ear or auditory nerve, a type of hearing loss that is associated with aging

presbycusis

accumulates in the external ear contributes to hearing loss especially in low frequency range

cerumen

what are the most common chief complaints of the ear

HPTELVDN

May occur suddenly or gradually, it may be sensorineural, or CNS disorders

hearing loss

maybe perceived as feeling of fullness in the ear, as a result of related problems of the nose, sinuses, oral cavity, or pharynx

pain

can be bloody(sanguineous),clear(serous), mixed(serosanguinous) or contain pus(purulent), may also be accompanied by an odor

ear drainage

maybe reported as high pitch or low pitch, loud, and persistent

tinnitus

maybe accompanied by vertigo or dizziness

loss of balance

what are the classifications of hearing loss

CSM

it involves interference with the conduction of sound impulses through the external auditory canal, the eardrum of the middle ear

conductive hearing loss

it is validated by rinne test

conductive hearing loss

results from disease or trauma to the inner ear or acoustic nerve

sensorineural hearing loss

it is validated by weber's test

sensorineural hearing loss

involves both conduction and sensorineural hearing loss

mixed hearing loss

give me five assessment in a client with hearing loss

DECAL

is a sensation of motion while the person is not moving or the client may feel he or she or the room is moving

vertigo

it's a sensation of unsteadiness and a feeling of movement within the head or lightheadedness

dizziness

it is used to assess the conduction of sound through the bone

weber's test

The sound is heard equally in both ears by bone conduction

normal

in one ear the sound is heard in the unaffected ear

sensorineural hearing loss

The sound is heard better in the affected ear

conductive hearing loss

compares air conduction to bone conduction and helps to differentiate conductive from sensorineural hearing loss

rinne test

air conduction is greater than bone conduction

normal, positive rinne test

The client hears better by air conduction

sensorineural hearing loss

bone conduction sounds louder

conductive hearing loss, negative rinne test

The examiner covers one ear with the palm of the hand then whispers softly two syllables from a distance of 1 to 2 ft

whisper voice test

a person can correctly repeat what was whispered

normal hearing acuity

test for vestibular ache

romberg test

assess the inner ear for balance

romberg test

if the patient loses balance this is a blank

positive romberg sign

it is the single most important diagnostic tool in detecting hearing loss

audiometry

it is performed to measure hearing comprehension

audiometry

an electronic instrument used to test hearing by producing sounds of varying pure tone frequencies and loudness

audiometer

the responses are plotted on a graph called

audiogram

ranges from minor difficulty in understanding the words or hearing certain sounds to total deafness

hearing impairment

results from the interference of sound transmission through the external ear and middle ear

conductive hearing loss

caused by impairment of the function of the inner ear, eight cranial nerve, or the brain

sensorineural hearing loss

a device designed to improve hearing which provides amplification to gather sound energy and directed to the air canal

hearing aid

a group of inflammatory diseases of the middle ear, most common in children

otitis media

what are the two main types of otitis media

acute otitis media and otitis media with effusion

an ear infection of abrupt onset that usually present with ear pain lasting for less than 6 weeks

acute otitis media

a feeling of fullness and define ass the presence of non-infectious fluid in the middle ear for more than 3 months

otitis media with effusion

fluid in the middle ear frequently causes conductive hearing impairment

otitis media with effusion

middle ear inflammation greater than 2 weeks that results in episodes of discharge of the ear "purulent otorrhea"

chronic suppurative otitis media

ear pain

otalgia

an incision into the tympanic membrane which fluid is removed by suction to relieve pressure and pus

myringotomy

swimmer's ear

otitis externa

an inflammation of the ear canal

otitis externa

characterized by accumulation of the endolymph in the inner ear

meniere's disease

endolymph burst from its normal channels in the year and flows into areas, causing damage

meniere's disease

reduce vertigo, nausea and vomiting, during an episode by suppressing vestibular activity

antihistamine

prescribe to increase sodium excretion through urine

diuretics

relieve nausea and vomiting by inhibiting medullary chemoreceptor triggers

antiemetics

to control vertigo

sedatives

an abnormal growth of the bone near the middle ear which can result in hearing loss

otosclerosis

a procedure where the mobile part of the stapes is removed and the hole is made in the fixed foot plate

stapedectomy

it is placed in the hole and cook around the incus to restablish a sound transmission

piston

a normal substance produced in the external ear

cerumen

can block sound from reaching the tympanic membrane

impacted cerumen
