What is the Rinne test used for?

The Rinne test differentiates sound transmission via air conduction from sound transmission via bone conduction. It can serve as a quick screen for conductive hearing lossconductive hearing lossConductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles). If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss.

Why is the Rinne test performed?

The Rinne test (/ˈrɪnə/ RIN-ə) is used primarily to evaluate loss of hearing in one ear. It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid. Thus, one can quickly screen for the presence of conductive hearing loss.

Where is Rinne test performed?

Rinne test: Place the base of a struck tuning fork on the mastoid bone behind the ear. Have the patient indicate when sound is no longer heard. Move fork (held at base) beside ear and ask if now audible. In a normal test, AC > BC; patient can hear fork at ear.

What is the difference between Weber and Rinne test?

Quote from video:
The rené test enables unilateral comparison of bone to air conduction. And takes advantage of the fact that physiologically. Sound conduction is more efficient via air than via bone.

Is Rinne test normal in sensorineural hearing loss?

AC > BC: Air conduction better than bone conduction (normal Rinne).

What test is used for sensorineural hearing loss?

The Weber test is a useful, quick, and simple screening test for evaluating hearing loss. The test can detect unilateral conductive and sensorineural hearing loss. The outer and middle ear mediate conductive hearing. The inner ear mediates sensorineural hearing.

What does it mean if bone conduction is greater than air conduction?

If the bone conduction is the same or greater than the air conduction, there is a conductive hearing impairment on that side. If there is a sensorineural hearing loss, then the vibration is heard substantially longer than usual in the air.

What is the Rinne test quizlet?

STUDY. Test. Hearing test that compares bone conduction with air conduction to assess whether hearing loss is sensorineural or conductive.

How can you distinguish between sensorineural and conductive hearing loss?

If the hearing loss is conductive, the sound will be heard best in the affected ear. If the loss is sensorineural, the sound will be heard best in the normal ear. The sound remains midline in patients with normal hearing. The Rinne test compares air conduction with bone conduction.

Why is Rinne positive in sensorineural deafness?

Rinne Positive: The patient is positive on that side (the ossicular chain is doing what it should be doing, acting as an amplifier). If the bone conduction through the mastoid process is heard louder than through the air, the patient is Rinne negative. This is always abnormal.

How do you remember Rinne and Weber?

Quote from video:
But our mnemonic to remember the rainy test is Rini under the penny.

How do you read Rinne and Weber test?

AC > BC: Air conduction better than bone conduction (normal Rinne). BC > AC: Bone conduction better than air conduction (abnormal Rinne).

Weber lateralizes Rinne test
Good ear AC > BC
Bad ear To bad ear BC > AC
Sensorineural loss
Good ear To good ear AC > BC

What does a positive Weber test indicate?

Weber test performance

A normal Weber test has a patient reporting the sound heard equally in both sides. In an affected patient, if the defective ear hears the Weber tuning fork louder, the finding indicates a conductive hearing loss in the defective ear.
