Otosclerosis
A-Deafness is the predominant symptom it is usually bilateral in 80% and it is
conductive type involve low frequency at begening
B-leads to sensori neural hearing loss
C-Carhart notch can be found on tympanometry
D-patient will never presented with Tinnitus and vertigo
E-Schwartz's sign is diagnostic and seen in all cases of otosclerosis
Clear

Sensorineural deafness caused by
A-Mumps
B- Tympanosclerosis
C-last stage of otosclerosis
D-Congenital ear atresia
E-Incudo-stapedial joint fixation

One of the following test has no benefit in the diagnosis of sensorineural deafness
A-Tympanometry
B-Otoacaustic emission
C-РТА
D-Auditory brainstem response(ABR)
E-Tuning fork test

Otosclerosis
A-The disease never invade the cochlea
B-normal bone replaced by new spongy osteoid bone
C- the commonest site 80% is the anterior margin of round window
D-Movement of stapes not affected by the disease process
E-Pregnancy is a protective process

Degree of deafness

A-Moderate degree (sound detected from between 25 -39 dB).

B-Severe degreesound detected from between 40 -69dB)

C-Mild degree sound detected from between 40 - 69 dB

D-( Severe degree (sound detected above 90 dB)

E-Mild degree (sound detected from between 25 - 39 dB).

Presbycusis

A-Autosomal dominant
B-disease defect is usually in the cochlear hair cells
C- affects first the lower tones
D- is one form of mixed hearing
E-loss is usually reversible

Moderate sensorineural hearing loss

A-Hearing threshold is from 56 to 70
B-Weber test will lateralize to better side
C-Rinne test is negative
D- Surgical treatment usually solve the problem
E-Child may detect loud sounds in the environment, but will not hear normal conversational speech

Sudden sensorineural hearing loss

A-low-molecular-weight dextran is contraindicated
B- is always bilateral

C-treated as out-patient condition
D- rinne is usually negative
E- is a medical emergency

Tuning fork test referred to as a (Rinne’s positive)

A-Seen in conductive deafness
B-If bone conduction more than air conduction
C-It found in healthy person

D-Tap a 512Hz tuning fork and place in the midline of the forehead
E-To compare the bone conduction of the patient with that of the examiner

In physiology of hearing, in middle ear, these sound vibrations make their way through the ossicles by:

A-The tympanic membrane will vibrate.
B-Movement of the hair cells
C-Lever mechanism

D-The auditory nerve picks up any neural signals
E-It vibrates the perilymph
