Question
What's Weber test and Rinne test
Answers
GPT-4o mini
The Weber test and Rinne test are two common clinical procedures used to assess hearing and help differentiate types of hearing loss.
### Weber Test
- **Purpose**: The Weber test is used to determine whether hearing loss is conductive or sensorineural.
- **Procedure**: A tuning fork is struck and placed in the center of the forehead (or on the top of the head).
- **Interpretation**:
- If sound lateralizes to one ear, it may indicate conductive hearing loss in that ear or sensorineural hearing loss in the opposite ear.
- **Example**: If a patient hears the sound louder in the left ear, it may suggest conductive hearing loss in the left ear or sensorineural loss in the right ear.
- If the sound is heard equally in both ears, hearing is likely normal, or there may be symmetrical sensorineural hearing loss.
### Rinne Test
- **Purpose**: The Rinne test helps compare air conduction (AC) and bone conduction (BC) of sound.
- **Procedure**: A tuning fork is struck and placed on the mastoid bone (bone conduction) until the sound is no longer heard, then the fork is moved to the front of the ear (air conduction).
- **Interpretation**:
- In a normal individual or with sensorineural hearing loss, air conduction is heard longer than bone conduction (positive Rinne test, AC > BC).
- In conductive hearing loss, bone conduction is heard longer than air conduction (negative Rinne test, BC > AC).
These tests are quick, simple, and help provide valuable information regarding the nature of a patient's hearing loss. They are often performed during a clinical examination by an otolaryngologist or a primary care physician.
