tympanic membran and external auditory meatus
|
|
|
What is Immittance Audiometry?
|

|
|
|
What does Type A tympanogram indicate?
|
Normal middle ear pressure and compliance
|
|
|
What does Type As tympanogram indicate?
|
Normal middle ear pressure but increased stiffness (otosclerosis)

Negative middle ear pressure (pure Eustachian tube function) is what type of tympnogram?
|
Type C
|
|
|
Type B Tympanogram
|
Increased mass (no eardrum movement) with normal canal volume (fluid within the middle ear cavity
|
|
|
the outer hair cells have an active function. The outer hair cells actually generate low intensity sounds which travel out from the cochlea into the middle and outer ear.
|
OEA's
|
|
|
What are Spontaneous OAE’s
|
Signals that occur in the ear canal without the introduction of any eliciting signal.
|
|
|
What are Evoked OAE’s ?

|
What does Electronystagmography (ENG) measure?
|
Measure eye motion using electrodes (or specialized virtual image glasses) to measure the presence of dizziness.
|
|
|
What does a Posturography assess?
|
Balance.
|
|
|
What is the purpose of the hearing handicapp scale?
|
obtain information about how the person views his/her hearing loss and to gain information useful in the aural rehabilitation process.
|
|
|
Disorders of the outer ear often result from what?
|
from structural defects during embryonic development.
|
|
|
What type of ear disoders consist of pathologies of the eardrum and in the middle ear cavity?
|
Middle Ear Disorders
|
|
|
What hearing disease is a disease of the cochlea resulting from excessive or overproduction of endolymph fluid. It is characterized by hearing loss, dizziness, tinnitus and a feeling of fullness in the ear. Usually unilateral, fluctuating and progressive (each episode increases the extent of the hearing loss
