Gelle's Test

This test was earlier done to confirm the presence of otospongiosis.ln this test, BC (bone conduction) is tested and at the same time Siegle's speculum compresses the air in the meatus. In normal individuals hearing is reduced after this; . Gelles test is positive; but in stapes fixation, sound is not affecteD. Gelles test is negative.

Basis of the Test

In normal individuals

In case of otosclerosis

t in air pressure in ear canal by siegel's speculum

Push the tympanic membrane and ossicles inward

t Intra labyrinthine pressure

Immobility of basilar membrane

↓ hearing

( test is positive)

t air pressure in ear canal by seigels speculum

Push the tympanic membrane

But ossicles are fixed

Hence this t ed pressure is not transmitted further

Hence no ..l- in hearing (. test is negative)

Note

Gelles test will also be negative in case of ossicular discontinuity
