Sources for Ear Pathologies

13 Nov

I think we have a paper due this next Friday?!  But it hasn’t been mention IN class (annoying) so I haven’t worked on it at all.  But here’s what I did at the beginning of the semester.  I need to pick something and get going!

ear art 3

-acute otitis media *I don’t think I’ll be able to use this–we’ll probably cover it exstensively in class*

is characterized by a short-lived infection (aural hematoma (feline)???

*-barotrauma

an injury to your ear because of changes in barometric (air) or water pressure. [D]

-bullous myringitis,

-Carhart notch

sensorineural component at 2000 Hz due to stapedial fixation; occurs with otosclerosis [C]

-Cholesteatoma

Invasion of Epithelium Cells of the EAM into the middle ear. Causes damage to ossicles, facial nerve, ad can be life threatening; Results from Chronic otitis media, marginal perforation of the TM, long periods of negative pressure with infection or PE tubes insertion [E]

-eosinophilic otitis media

Eosinophilic otitis media is an intractable middle ear disease associated with bronchial asthma and nasal allergy that sometimes induces deterioration of sensorineural hearing loss. How eosinophils accumulate in the middle ear has yet to be determined; active eosinophilic inflammation may occur in the entire respiratory tract, including the middle ear, in patients with this disease. EOM often produces a yellow and highly viscous middle ear effusion and can cause symptoms that range from prolonged hearing loss and otorrhea to sudden deafness. The middle ear symptoms are unresponsive to conventional treatments for otitis media and are instead treated with steroids [A]

***-Glomus Jugulare

Dilation of the internal jugular vein impairing ossicular movement. Can hear heart beat.

-Goldenhar Syndrome

-granular myringitis,

*-Malingering *we talked about this in class a little, plus it’s not really a hearing/anatomical problem*

Individual is actively faking a hearing loss. [E]

*-Mastoiditis

Mastoid air cells become infected. Life threatening Meningitis [E]

**-Meniere’s disease., {pics} *I’m sure we’ll cover this in detail*

could be progressive, Sx: fullness,dizziness [B]

Meniere Episodes = Rotary vertigo, tinnitus, ear fullness or pressure, nausea, and hearing loss. Can last minutes to hours. [E]

-meningitis *I wrote my Aural Rehab paper on this, so I have a framework to start.  It’s such a huge cause of hearing loss that we might discuss it in class though*

-mumps *part of meningitis–the agent that gets it started?  Along with chicken pox?*

-Otosclerosis.

Fixation of stapes (calcified), so increase in mass of ossicles. Conductive HL, seen in audiogram at 2000 Hz called “Carhart Notch”. Tx: stapedectomy [B]

Fixation of the foot plate of the stapes in the oval window; Autoimmune disease. Higher occuring in caucasians and women.

–>parasites (feline)???

*-Perilymphatic Fistula

Rupture of the oval or round window causing a loss in perilymph. This causes hearing and balance problems. [E]

*-Psychogenic  *Nope, psychological*

Individual does not have a hearing loss but they truely believe they do. Usually result of emotional trauma [E]

-stenosis

acquired– abnormal narrowing of ear canal [C]

**–>Suppurative otitis: (feline)???

The ears of kittens and cats are liable to infection from pus producing organisms

-Swimmer’s Ear {pics}

*-Tinnitus,

a roaring in your ears, can be the result of loud noises, medicines or a variety of other causes. [D]

**-Toxoplasmosis

-Usher Syndrome

-vestibular schwannoma

An acoustic neuroma is a slow-growing tumor of the nerve that connects the ear to the brain. This nerve is called the vestibular cochlear nerve. It is behind the ear right under the brain. An acoustic neuroma is not cancerous (benign), which means it does not spread to other parts of the body.

-Waardenburg Syndrome
