Q

The ankylosis of the bones of the middle ear, resulting in a conductive hearing loss. This condition is treated with a stapedectomy.

A

otosclerosis [Ankylosis means fused together.]

23
Q

Inflammation of the labyrinth that can result in vertigo and deafness.

A

labyrinthitis

24
Q

A sense of whirling , dizziness, and loss of balance that are often combined with nausea and vomiting. Although it is a symptom of many disorders, recurrent vertigo is sometimes associated with inner ear problems such as Meniere’s disease.

A

vertigo

25
Q

A rare chronic disorder in which the amount of fluid in the inner ear increases intermittently, producing attacks of vertigo, a fluctuating hearing loss (usually in one ear), and tinnitus.

A

Meniere’s disease

26
Q

A condition of a ringing, buzzing, or roaring sound in one or both ears. It is often associated with hearing loss and is more likely to occur when there has been prolonged exposure to loud noises.

A

tinnitus

27
Q

A brain tumor that develops adjacent to the cranial nerve running from the brain to the inner ear. This is one of the most common types of brain tumors and can cause hearing loss, vertigo, and tinnitus.

A

acoustic neuroma

28
Q

The complete of partial loss of the ability to hear. It can range from the inability to hear sounds of a certain pitch or intensity, to a complete loss of hearing.

A

deafness

29
Q

A gradual loss of sensorineural hearing that occurs as the body ages.

A

presbycusis

30
Q

Occurs when sound waves are prevented from passing from the air to the fluid-filled inner ear. Caused of this hearing loss include a buildup of earwax, infection, fluid in the middle ear, a punctured eardrum, otosclerosis, and scarring. This type of hearing loss can often be treated.

A

conductive hearing loss

31
Q

Develops when the auditory nerve or hair cells in the inner ear are damaged. This is usually due to age, noise exposure, or an acoustic neuroma. The source of this hearing loss can be located in the inner ear, in the nerve from the inner ear to the brain, or in the brain.

A

sensorineural hearing loss, aka nerve deafness

32
Q

A type of nerve deafness caused by repeated exposure to extremely loud noises such as a gunshot, or to moderately loud noises that continue for long periods of time.

A

noise-induced hearing loss [Any sound above 85 decibels (dB) can cause some hearing loss if the exposure is prolonged.]

33
Q

(1) Commonly used as the measurement of the loudness of sound.
(2) Sound is measure in two ways - this is a measure of sound frequency that determines how high or low a pitch is.

A

decibel (dB)

hertz (Hz)

34
Q

The measurement of the ability to hear and understand speech sounds based on their pitch and loudness. This testing is best achieved in a sound-treated room with earphones.

A

audiological evaluation, aka speech audiometry [The resulting graph is an audiogram that represents the ability to hear a variety of sounds at various loudness levels.]

35
Q

The use of an audiometer to measure hearing acuity. An audiometer is an electronic device that produces acoustic stimuli of a set frequency and intensity.

A

audiometry

36
Q

An instrument used to examine the external ear canal.

A

otoscope

37
Q

A type of test that involves one ear.

A type of test that involves both ears.

A

monaural testing

binaural testing

38
Q

The use of air pressure in the ear canal to test for disorders of the middle ear. This is used to test for middle ear fluid buildup or eustachian tube obstruction, or to evaluate a conductive hearing loss.

A

tympanometry [The resulting record is a tympa-nogram.]

39
Q

Use of a tuning for to distinguish btw conductive and sensorineural hearing losses. The patient’s perception of the tuning fork’s vibrations help evaluate his or her hearing ability by air conduction compared to that of bone conduction.

A

Weber and Rinne tests

40
Q

The surgical repair, restoration, or alteration of the pinna of the ear. This is sometimes done as a cosmetic surgery called ear pinning to bring the ears closer to the head.

A

otoplasty

41
Q

Tiny ventilating tubes placed through the eardrum to provide ongoing drainage for fluids and to relieve pressure that can build up after childhood ear infections.

A

ear tubes, fka tympanostomy tubes

42
Q

The surgical removal of the mastoid cells. This procedure is used to treat mastoiditis that cannot be controlled with antibiotics or in preparation for the placement of a cochlear implant.

A

mastoidectomy

43
Q

A small surgical incision in the eardrum to relieve pressure from excess pus or fluid, or to create an opening for the placement of ear tubes.

A

myringotomy

44
Q

The surgical removal of the top portion of the stapes bone and the insertion of a small prosthetic device known as a piston that conducts sound vibrations to the inner ear.

A

stapedectomy

45
Q

The surgical correction of a damage middle ear, either to cure chronic inflammation or to restore function.

A

tympanoplasty

46
Q

The surgical removal of all or a portion of the labyrinth. This procedure is performed to relieve uncontrolled vertigo; however, it causes complete hearing loss in the affected ear.

A

labyrinthectomy

47
Q

A form of physical therapy designed to treat a wide variety of balance disorders, the majority of which are caused by problems in the inner ear and vestibular nerve.

A

vestibular rehabilitation therapy

48
Q

Transmits, processes, or amplifies sound, and can be used with or withou a hearing aid.

A

Assistive listening devices (ALD) [An ALD can be helpful in eliminating distracting background noises. The American with Disabilities Act (ADA) requires that many public places provide assisted listening devices.

49
Q

An electronic device that bypasses the damaged portion of the ear and directly stimulates the auditory nerve. The external speech processor captures sound & converts them into digital signals. Electrodes that are implanted in the cochlea receive the signals and stimulate the auditory nerve. The brain receives these signals & perceives them as sound.

A

cochlear implant

50
Q

A surgical procedure in which a new opening is created in the labyrinth to restore lost hearing.

A

fenestration [fenestr/a = window]

51
Q

An electronic device that is worn to correct a hearing loss. Sometimes a sensorineural hearing loss can be corrected with this device.

A

hearing aid

52
Q

An external electronic device that uses a microphone to detect and amplify sounds.

A

analog hearing aid

53
Q

Uses a computer chip to convert the incoming sound into a code that can be filtered before being amplified. This is designed to best compensate for a specific type of hearing loss.

A

digital hearing aid
