What type of hearing loss is suggested if sound lateralizes to one ear in the Weber test?

In the Weber test, sound lateralization to one ear indicates differences in hearing sensitivity between the two ears. When sound is perceived to lateralize to a specific ear, it suggests that there is some form of hearing loss in the opposite ear.

If the sound lateralizes to one ear, this could indicate either conductive hearing loss in the ear receiving the sound or sensorineural hearing loss in the ear opposite to the sound. In the case of conductive hearing loss, the affected ear would not conduct sound as effectively, making it perceived louder in the ear that is functioning normally. Conversely, sensorineural hearing loss in the opposite ear would result in reduced sound perception on that side, which would also cause the sound to lateralize to the ear with better hearing acuity.

Understanding this distinction is crucial for interpreting the results of the Weber test accurately. It highlights the importance of further testing and evaluation to determine the exact nature of the hearing loss, leading to appropriate diagnosis and management.
