Gelles Test | Tuning Fork Test | ENT

Gelle test:

In this test, the air pressure in the external canal is varied using a Siegle’s speculum. The vibrating fork is held in contact with the mastoid process. In normal individuals and in those with sensorineural hearing loss, increased pressure in the external meatus causes a decrease in the loudness of the bone conducted sound. In stapes fixation no alteration in the hearing threshold is evident.
