Hearing Disorders Paper [Possible Topics]

20 Aug

You know how I like getting ahead.  I have this short paper due (hopefully individually written, and not presented) at the end of the semester.  Here are some aural pathologies I found, a short description (not my own), a couple of pics, and ones I may be interested in.  It would be SUPER helpful if any of there occur in people and cats–so I could use work to look at a case, get info, and maybe take a real-life pic.  We’ll see about that. . .

-acute otitis media

is characterized by a short-lived infection (< 3 mo) that may be initially viral and then bacterial in origin.[3] Patients generally experience pain and some hearing loss and often develop a fever. Discharge from the ear usually accompanies this infection in patients with acute suppurative otitis media [A]

***-Adhesive Otitis Media

glue ear” TM becomes wrapped upon ossicles; Results from serous otitis media

Asteatosis

Diminished or arrested action of the sebaceous glands; eczema, old age, cleaning of EAM [E]

–>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

Individual is actively faking a hearing loss. [E]

*-Mastoiditis

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

**-Meniere’s disease., {pics}

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

mumps

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

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.
