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

14 years old female presented with hearing loss for the last 2 weeks preceded by upper respiratory tract infection, ears examinations showed retracted, dull looking tympanic membranes with shuttering of the cone of light No history of hearing problem was reported before the recent complaint All of the below are true regarding the pre mentioned case except

A-Webber reports no lateralization
B- Surgery by myringotomy and insertion of ventilation tube may be indicated
C-Sensori neural hearing loss
D-Rinne negative
E-air bone gap by pure tone audiogram
