Hearing Test (Rinne and Weber Examinations) - ENT

Summary

This video demonstrates how to perform the Rinne and Weber tests using a 512 Hz tuning fork to assess hearing loss. It guides viewers through activating the tuning fork, positioning it correctly for air and bone conduction tests, and clearly explaining the procedure to patients. The Rinne test involves holding the vibrating tuning fork perpendicular to the external auditory canal for air conduction, while bone conduction is assessed by placing the fork’s base on a bony area. The Weber test is performed by placing the base of the fork on the midline of the head to determine which ear perceives the sound most strongly, aiding in identifying hearing impairments.

Takeaways

• 🔊 The tuning fork tests are useful for assessing hearing loss.
• 🎵 The Renee and VOR tests are commonly performed using a 512 Hz tuning fork.
• ✋ The tuning fork can be activated by flicking it between fingers or tapping it on the knee.
• 🗣️ It is important to clearly explain the test to the patient before starting.
• 👂 Patients are asked to indicate in which position (A or B) the sound is louder.
• 💨 Position A tests air conduction of sound.
• 🦴 Position B tests bone conduction by placing the base of the tuning fork on a bony area.
• 📏 When testing air conduction, the tuning fork should be held perpendicular to the external auditory canal, about 1 cm away.
• -
• 🔄 During testing, ensure the patient understands to report which ear hears the sound loudest or if it is heard in the middle.
• -
• 🎯 The base of the tuning fork can be placed in the midline for certain assessments.

Q & A

What is the primary purpose of the Tuning Fork tests described in the video?

The primary purpose of the Tuning Fork tests is to assess hearing loss by evaluating air conduction and bone conduction of sound.

Which tuning fork frequency is used for the Renee and VOR tests in the video?

A 512 Hz tuning fork is used for performing the Renee and VOR tests.

How can the tuning fork be activated before performing the test?

The tuning fork can be activated by flicking it between the fingers or by tapping it on the knee.

Why is it important to explain the test clearly to the patient?

Explaining the test clearly ensures that the patient understands what they need to do, which improves the accuracy of their responses.

What does Position A of the test assess?

Position A assesses air conduction by holding the vibrating tuning fork near the external auditory canal.

What does Position B of the test assess?

Position B assesses bone conduction by placing the base of the tuning fork on a bony area near the ear.

How should the tuning fork be positioned for air conduction testing?

For air conduction testing, the tuning fork should be held perpendicular to the external auditory canal, about 1 cm away, not parallel.

What instruction should be given to the patient regarding the sound during the test?

The patient should be asked to indicate whether they hear the sound louder in the left ear, right ear, or in the middle.

Where should the tuning fork be placed to test sound perception in the midline?

The base of the tuning fork should be placed on the midline of the head to test whether the sound is perceived equally by both ears.

Why is bone conduction testing important in hearing assessments?

Bone conduction testing helps distinguish whether hearing loss is due to problems in the outer/middle ear (conductive) or in the inner ear/auditory nerve (sensorineural).

What is the main difference in patient perception between air conduction and bone conduction tests?

In air conduction tests, the sound travels through the ear canal and middle ear, while in bone conduction tests, the sound bypasses the outer and middle ear, directly stimulating the cochlea.
