Prolapsed canal,

Back 17

Prolapsed canal, associated with the aging process, is a breakdown or sag of tissue around the canal. It causes the walls of the canal to collapse. A flap of tissue can partially or completely block the external canal. The canal will open up by lifting the pinna upward and backward.

Otosclerosis

Back 30

disease of spongy changes surrounding inner ear. when hardened they become sclerotic. stapes becomes fixed causing HL of 60 to 65 dB, often with tinnitus. most oten in caucasian women who inherited, can be triggered by pregnancy

Front 31

Otitis media

Back 31

fluid in the middle ear. Suppurative otitis media = bacterial infection. Chronic suppurative otitis media, or 'running ear.' The perforation in the pars tensa portion of the eardrum will not heal and gradually enlarges. Infection erodes some parts of the ossicular chain, corrected by mastoidectomy with tympanoplasty. Non-Suppurative otitis media is also called areo-otitis media, serous otitis media, middle ear effusion, mucoid otitis media, or 'glue ear' = non-bacterial (often sterilized by antibiotics), a BAHA may be a good fit

Front 32

tympanoplasty

Back 32

repairs the ossicular chain, or replaces diseased bones with a prosthesis

Front 33

mastoidectomy

Back 33

removing diseased mastoid cells often prior to a tympanoplasty. Removal of the ossicular chain and mastoid air cells, = radical mastoidectomy

Front 34

barotrauma

Back 34

when the Eustachian tube does not open properly allowing for PE, serum collects in the middle ear. The drum appears normal, but with a bluish or yellowish light reflex. Often, a fluid line or bubbles show behind the drum. Tymp = A neg

Place Theory

Back 42

says there are specific places in the cochlea, the pathways to the brain and the temporal lobe, itself, for specific frequencies

Front 43

Volley Theory

Back 43

says that there are sequences of firing which allow for the transmission of neural energy from the inner ear to the brain at rates faster than any single nerve fibers could fire.

Front 44

Temporal Theory

Back 44

holds that at or below 1000 Hz, the place theory is correct. Above 1000 Hz, nerve fibers fire in volleys.

Tinnitus Types

Back 46

Cochlear (sensoinurial) - if bilateral hear in center, if monaural - the sensation manifests from the worse ear but switches to the better ear once fited monaurally - often aleviated with HI, Central - fm head trauma, not alleviated by HA, Objective = conductive - often can be heard through listener, not reduced by amplification but might be through chiro, PT, etc.

Front 47

Vertigo

Back 47

hallucination of movement, arising from problems within the vestibular portion of the inner ear. The world spins about the client, or, the client feels that there is moving in space. Dizziness is a giddy or swimming sensation, and is not vertigo.

Front 48

Organ of Corti

Back 48

rests on basilar membrane, overhanging portion = tectoral membrane, consists of columns of inner (one row) and outer rods with hair cells (three rows) (cilia) at the top of the rods. Supporting cells hold these rods and hair cells in place.
