What does a positive Weber test indicate?

A positive Weber test indicates lateralization to one ear, which suggests that there may be an abnormality in hearing function. In a healthy individual, sound will be perceived equally in both ears. However, when the sound lateralizes to one ear during the Weber test, it typically points to either sensorineural hearing loss in the ear not receiving the sound or conductive hearing loss in the ear that receives the sound.

For instance, if the tuning fork is placed in the center of the forehead and the sound is perceived louder in one ear, it suggests that the opposite ear may have some form of hearing loss. This test is a useful tool in differential diagnosis and can help direct further assessment and intervention necessary for managing the patient’s hearing concerns. Technical understanding of auditory pathways and the distinction between conductive and sensorineural hearing conditions is essential for interpreting the results accurately.
