Answer 6

painless, slowly growing solid tumour that distorts the auricle and destroys the normal architecture (auricle disorder)

Question 7

Cauliflower ear

Answer 7

caused from repeated blows to the ear, fluid and blood fill the space and harden, causing permanent deformity (auricle disorder)

Question 8

Perichondritis of the auricle

Answer 8

complication of an ear-piercing, looks ready to burst, skin is red and warm

Question 9

Auricular hematomas

Answer 9

caused by direct trauma to the pinna, torn perichondria vessel bleed between the detached perichondrium and underlying cartilage

Question 10

Psoirasis of the external ear

Answer 10

itchy, flakey skin inside the ear (auricle disorder)

Question 11

Bifid earlobe

Answer 11

earlobe is divided into two small sections (auricle disorder)

Question 12

Supernumerary auricle

Answer 12

it does not affect hearing, just doesn’t look ecstatically

appealing (auricle disorder)

Question 13

Cerumen

Answer 13

causes a conductive hearing loss, affects localization of sound, loss of approximately 45dB for conductive hearing loss (EAC disorder)

Question 14

Stenosis

Answer 14

narrowing of the body Canal (EAC disorder)

Question 15

Atresia

Answer 15

complete blockage of the canal, loss of 60dB of hearing, this is when bone conduction picks up (EAC disorder)

Question 16

Otomycosis

Answer 16

fungal ear infection (EAC disorder)

Question 17

Osteomyelitis

Answer 17

infection of bone, the infection reaches the temple bone (thin wall) (EAC disorder)

Question 18

Otalgia

Answer 18

ear pain (EAC disorder)

Question 19

Furunculosis

Answer 19

infection of ear hair follicles (EAC disorder)

Question 20

Perforation from trauma or pressure

Answer 20

rupture of the tympanic membrane, can occur from physical damage to the ear (high impact) or change of pressure (TM disorder)

Question 21

Myringotomy

Answer 21

opening of the eardrum to drain fluid- surgeons use zigzag cigarette paper to repair the tympanic membrane

Question 22

Otitis media

Answer 22

occurs in the mucous lining of the middle ear space, Eustachian tube is not functioning properly, fluid builds up and becomes infected (ME disorders)

Question 23

Facial Palsy

Answer 23

muscles on one side of the face become weak or paralyzed - trauma to 7th cranial nerve (ME disorder)

Question 24

Barotrauma

Answer 24

caused by an increase in air or water pressure (airplane or sub diving) (ME disorder)

Question 25

Cholesteatoma

Answer 25

Onion like structure (tumble weed), interferes with the ossicles, must be surgically removed, but can come back (ME disorder)

Question 26

Otosclerosis

Answer 26

originates in the inner ear, but makes its way to the middle ear. Causes conductive hearing loss, it affects the stapes - spongey like growth, footplate becomes fixated on the oval window, and this limits the vibration transmitted to inner ear (ME disorder)

Question 27

Tympanoplasty

Answer 27

repair possibles or tympanic membrane, substitute metal or plastic prosthetic for damaged area

Question 28

Stapedotomies

Answer 28

small, fenestra strapedectomies

Question 29

Stapedectomoes

Answer 29

removal of the stapes, prosthetics replace it

Question 30

stapes mobilization

Answer 30

stapes is broke, for off sponginess to stiffen it

Question 31

Hemotympanum

Answer 31

bleeding in the middle ear from any cause (ME disorder)

Question 32

Tympanosclerosis

Answer 32

calcium deposits sometimes form on the tympanic membrane, results in this condition (ME disorder)

Question 33

Vertigo

Answer 33

results from damage to the vestibular system, it is a sensation of true "tuning", crystals rub hair cells the wrong way

Question 34

SNHL (Sensory Neural Hearing Loss)

Answer 34

damage to 8th CH, typically affect high frequencies - hard to discriminate /f/, /t/, /k/

Question 35

Dusplacusis bonmules

Answer 35

interpret the sound different (double hearing) - right ear hears one thing, left ear hears another

Question 36

Bilarlus monoralis

Answer 36

one ear is hearing some thing different

Question 37

Sudden Idiopathic Sensory/ Neural Hearing Loss

Answer 37

hearing loss- usually unilaterally, may develop over a couple days or even overnight

Question 38

Meniere's Disease

Answer 38

another cause of unilateral hearing loss

Question 39

Semicircular Canal Dehiscence Syndrome

Answer 39

symptoms : dizziness, vertigo, disequilibrium - often misdiagnosed

Question 40

Autoimmune Inner-Ear disease

Answer 40

specifically attacks its own tissues because it fails to distinguish them from bacteria, viruses, etc.

Answer 41

- temporary threshold shift | - permanent threshold shift

Answer 42

advancing age results in hearing loss
