Genetic or Hereditary Disorders Definitions External Ear Ear Canal Disorders TM/ME Disorders
100
What is an aquired hearing loss?
This term refers to HL that occurs after birth and is usually caused by trauma, diseases, drugs, or aging
100
What is an acute disorder?
This term refers to a disorder that is in its initial phase and lasts for a relatively short duration
100
What are preauricular skin tags or pits?
This is a small dimple anterior to the tragus or the small skin growth anterior to the tragus.
100
What are exostoses?
This disorder, also known as "surfer's ear", causes bony outgrowths covered with skin that occurs in the external ear canal from repeated and prolonged exposure to cold water. It is usually bilateral, painless, non-problematic, and does not lead to HL unless it leads to a secondary problem
100
What is a monomere?
An area in the TM without the fibrous tissue layer
200
What is Connexin-26?
This is the most common genetic cause of HL and may be expressed at birth or at a later prelinguistic stage
200
What is a chronic disorder?
This is a condition that is persistent over a relatively long period of time
200
What is auricular hematoma?
This is internal bleeding within the auricle that may lead to damage to the cartilage.
200
What is an osteoma?
These are rounded pearl-shaped bony growths in the ear canal that occur spontaneously and are benign tumors. They are typically unilateral and HL does not occur.
200
What is "patent"?
This term means open and allows us to know if the PE tube is open and functioning properly.
300
What is the outer/middle ear?
Treacher Collins, DeGeorge, Goldenhar, Paget, Alport genetic disorders that affect which portions of the auditory system?
300
What is an intermittent disorder?
This is a condition that comes and goes or reoccurs often
300
What is atresia?
The absence of an external auditory canal due to embryological events that may be unilateral, or bilateral, in which surgical correction is more likely.
300
What is pseudomonas?
This is is the most common bacteria that cause otitis externa
300
What is a cholesteatoma?
A benign mass that develops in the ME space and is secondary to a perforation or otitis media. It is typically unilateral in nature, causes foul-smelling otorrhea, and causes a CHL or mixed HL depending on the extent of the damage. It occurs when dead skin tissue and keratin are trapped in a surrounding area of healthy skin and the growth can destroy surrounding structures and bony shelf.

-medically corrected/removed
400
What is the cochlea?
Usher, Jervell and Lange-Nielsen, Herrmann, Alport, Klippel-Feil, Waardenburg are genetic disorders that affect which specific structure of the auditory system
400
What is a physician?
A medical diagnosis can only be made by this person
400
What is stenosis?
An abnormal narrowing of the external auditory canal is usually due to developmental abnormalities. The ear canal is less than 4 mm in diameter which prevents accurate pure tone thresholds if supra-aural headphones are used. Patients with this are often more prone to ear infections or HL.
400
What is otitis media?
This is an accumulation of fluid called effusion which occurs in the middle ear. Young children are most affected due to anatomical differences in ET orientation. It is unilateral or bilateral and can cause a mild to moderate CHL.
400
What is a retraction pocket?
the most common origin of an acquired cholesteatoma is from this area of the Pars Flaccida region of the TM
500
What is congenital hearing loss?
This term refers to hearing loss that is present at birth and may be prenatal when it occurs prior to birth or perinatal in which it occurs during birth.
500
What is idiopathic?
A disorder that occurs in which there is no known cause is referred to as this.
500
What is impacted cerumen
This disorder causes a mild conductive loss that is usually unilateral but can be bilateral and it is treated with curettes, suction, or irrigation.
500
What is a myringotomy?
This procedure is a removal of the ME fluid with a needle-type syringe performed by a physician
500
What is otosclerosis?
This is a spongy bony outgrowth on the stapes footplate that becomes hardened or sclerotic. It is more prevalent in females 20-40 years, hormonal changes, and is a late-onset genetic disorder. It causes CHL from the stapes fixation and is unilateral to progressive bilateral. Audiograms will show 2000 Hz Carhart's notch which relates to the inertial mode of BC, and a normal type A tympanogram, with no ARTs. It can be surgically treated, with a stapedotomy or stapedectomy.
