TUNING FORK TESTS

Tuning fork tests are an integral part of ear examination which help us assess the FUNCTION of the ear....HEARING.
There are many Tuning fork tests but the commonly performed are 3
1) Rinne's Test
2) Weber's Test
3) Absolute Bone Conduction Test
The tests essentially tell us whether the hearing loss is....
a) CONDUCTIVE...the pathology is in the EXTERNAL EAR +/- MIDDLE EAR.....Treatment is Medical +/- Surgical.
b) SENSORI NEURAL...the pathology is in the INNER EAR or beyond....Providing a commensurate hearing aid is the only treatment.
c) MIXED
So the competence to perform these tests properly is mandatory .
The tests need to be discussed under the following headings
Principle
