SLHS 340 EXAM 3

what is tinnitus? - Correct Ans-ringing in the ears what is a genetic hearing loss? - Correct Ans-due to differences in the genes that are passed on through a hereditary source what is aural fullness? - Correct Ans-a sense of pressure in the ear and can be a sign of fluid in the middle ear or some types of sensorineural HL what is considered an early onset genetic hearing loss? - Correct Ans-during infant toddler stage what is considered a late onset genetic hearing loss? - Correct Ans-during childhood or adult stages what is a congenital hearing loss? - Correct Ans-one that is present at birth can be prenatal (prior to birth) can be perinatal (during birth) what is an acquired hearing loss? - Correct Ans-a hearing loss that is not of genetic or congenital origin occurs after birth and is usually caused by disease, trauma, drugs, or aging what is an acute disorder? - Correct Ans-a condition that is in its initial phase and lasts and relatively short duration what is a chronic disorder? - Correct Ans-a condition that is persistent over a relatively long period of time what is is an intermittent disorder? - Correct Ans-a condition that comes and goes or reoccurs often what is otorrhea? - Correct Ans-fluid (usually infected) that is draining into the external auditory canal from the middle ear what does idiopathic mean? - Correct Ans-the cause is unknown what are 3 auricular malfunctions? - Correct Ans-microtia anotia atresia what is anotia? - Correct Ans-absent pinna only an issue if it causes closure of ear canal SLHS340 SLHS340 how can anotia be managed? - Correct Ans-usually fixed surgically with pinna reconstruction issue is more cosmetic, especially if necessary for glasses or hearing aids what is microtia? - Correct Ans-an abnormally small and malformed auricle only an issue if ear canal is impeded *be careful with supraurals what is atresia? - Correct Ans-absence of an external auditory canal due to embryologic events (may be uni or bilateral) causes a max. conductive HL of 50-60dB HL how can atresia be managed? - Correct Ans-surgery is a possibility or hearing aids do auricular pathologies typically cause hearing loss? - Correct Ans-no what is an auricular hemotoma? - Correct Ans-internal bleeding within the auricle that may lead to damage to the cartilage what is excessive cerumen? - Correct Ans-an acquired disorder of the external auditory canal that occurs when there is an over-accumulation of cerumen that becomes impacted somewhere along the length of the canal if excessive cerumen is impacted, what type of results will it show? - Correct Ans-flat conductive loss, flat tymp, and no acoustic reflex what are some examples of foreign objects children get stuck in their ears? - Correct Ans-cotton swabs, sand, insects, earrings, clay, food, beads, pen caps, small batteries, and pieces of glass what is stenosis? - Correct Ans-an abnormal narrowing of the external auditory canal, usually due to developmental anomalies common in people with Down syndrome *does not cause HL what is a collapsing canal? - Correct Ans-when the ear canal collapses due to pressure on the pinna prevalent in older adults can be uni or bi lateral *can cause artificial hi freq conductive loss when using supra-aurals what is exostosis? - Correct Ans-"surfer's ear" a condition of bony outgrowths, covered with skin, that occur in the external ear canal result from irritation of the ear canal due to repeated and prolonged exposure to cold water precise cause = unknown SLHS340 SLHS340 usually bilateral *only causes HL when they are 'kissing' what is otitis externa? - Correct Ans-"swimmer's ear" an infection of the tissues lining the external ear canal usually caused by bacteria or fungus symptoms include redness, itching, and pain does not cause HL unless canal swells shut treatment: antibiotics and cleaning do middle ear disorders commonly cause hearing loss? - Correct Ans-yes, conductive what is otitis media? - Correct Ans-an accumulation of fluid called effusion which occurs in the middle ear can be uni or bi lateral most common in children (2yo) what is serous otitis media? - Correct Ans-when the fluid in the middle ear is clear and non-infected what is secretory otitis media? - Correct Ans-similar to serous, non-infected but much thicker what is purulent/suppurative otitis media? - Correct Ans-when the fluid of the middle ear is infected and is now in contact with ME bones what type of results will otitis media show? - Correct Ans-may cause mild conductive if severe enough tymps will be flat no acoustic reflex normal ear canal volume (1) what is the treatment for otitis media? - Correct Ans-antibiotics PE tubes, if chronic tonsillectomy and adenoidectomy (can cause ET blockage) what is eustachian tube dysfunction? - Correct Ans-the underlying occurrence of otitis media when the ET is unable to equalize the air pressure in the middle ear, creating a negative pressure in the middle ear as the remaining air becomes absorbed by tissues of the middle ear negative middle ear pressure may also result from a relatively sudden change in external air pressure called what? - Correct Ans-barotrauma SLHS340 SLHS340 what is a pressure equalization tube and when is it used? - Correct Ans-used for patients with consistently reoccurring otitis media a small grommet-like tube inserted into the TM to allow the fluid to drain, provides a mechanism to equalize air pressure in the middle ear how does fluid in the middle ear cause heari
