OTOLARYNGOLOGY

ORL - 1
About the function of the outer hair cells we can get
objective information on
A) tympanometry
B) BERA
C) otoacoustic emission
D) investigation of stapedial reflex
C) otoacoustic emission
The otoacoustic emission objectively registers the low intensity
sounds at the external ear canal,that have been produced by
the outer hair cells.

ORL - 2
The term "acoustic impedance" refers to the
A) pressure in the middle ear.
B) resonancy of the external ear.
C) hearing loss of inner ear origin.
,D) acoustic resistance.
E) spatial hearing.
D) acoustic resistance.
The part of the middle ear (tympanic membrane and ossicular
chain) create an acoustic resistance against the sound wave
pressure.

ORL - 4
The patients has no ear pain in:
A) perichondritis of the ear
B) herpes zoster oticus
C) angina
D) otosclerosis
E) lymphadenitis of the neck
D) otosclerosis
In the case of otosclerosis, there is no pain but only hearing
loss.

ORL - 5
Rinne's test is informative in:
A) conductive hearing loss
B) sensorineural hearing loss
,C) perforation of the tympanic membrane
D) sudden hearing loss
A) conductive hearing loss
In Rinne test the patient hears the transmitted sound better on
the bone due to bone conductivity, rather than in the air. This
indicates a conductive hearing loss.

ORL - 7
Tenderness with pressure on the tragus or traction on the
auricle is typical in:
A) othematoma
B) external otitis
C) mastoiditis
D) otosclerosis
B) external otitis
Tenderness with pressure on the tragus or traction on the
auricle is characteristic in cases of external ear infections.

ORL - 9
The patient suffers from vertigo and unilateral hearing loss
and tinnitus for 1 hour. The probable diagnosis is:
A) acoustic neurinoma
, B) neuronitis vestibularis
C) vertebrobasilar insufficiency
D) Ménière's disease
D) Ménière's disease
The Ménière disease is characterized by a continues spinning
vertigo, lasting for at least 1-2 hours, accompanied by tinnitus
and unilateral hearing loss. In later phase the tinnitus and
hearing loss can be permanent.

ORL - 10
The patient suffers from hearing loss on the right side.
Weber test is lateralized to the right side. Probable cause of
the hearing loss is:
A) otosclerosis on the left side
B) cerumen on the right side
C) Ménière's disease on the right side
D) sensorineural hearing loss on the right side
B) cerumen on the right side
Weber test is heard louder to the affected side due to
conductive hearing loss in the defective ear. The reason of
conductive hearing loss most of the times is the existence of
earwax.
