Galle’s test is used for ?
a) Otosclerosis
b) Juvenile angiofibroma
c) Nasal polyp
d) None
Correct Answer - A
Ans. is ‘a’ i.e., Otosclerosis
Gelle’s test
It is a bone conduction test and examines the effect of increased air
pressure in ear canal on hearing.
Increased air pressure in ear canal (by Siegle’s speculum) pushes
the tympanic membrane and ossicles inwards which raises the
intralabyrinthine pressure and causes immobility of basilar
membrane and decreased hearing.
However, if ear ossicles are already fixed or disconnected, the
pressure cannot be transfered to inner ear
No change in hearing in this situation.
Base of vibrating tuning fork is placed on mastoid process and air
pressure in ear canal increased (by Siegle’s speculum).
Interpretation are : -
Positive Gelle’s (decreased hearing on increased pressure)→
Normal or sensorineural hearing loss. h)
Negative Gelle’s (No effect of pressure change in hearing) →
Disconnected or fixed ossicular chain.
