Hearing loss in one ear

What is unilateral hearing loss?

Unilateral hearing loss (UHL) means that you experience a loss of hearing in the right ear, or the left ear, but not both. In contrast, bilateral hearing loss is when hearing loss affects both ears.

Unilateral hearing loss, sometimes called single-sided deafness (SSD) or deafness in one ear, affects millions of people all around the world.

Should you have a hearing test?

Conductive vs. sensorineural unilateral hearing loss

Unilateral conductive hearing loss

Conductive hearing loss occurs when sounds can't pass freely through the eardrum or past the tiny bones, known as ossicles, in the middle ear. This is due to a breakdown in the effectiveness of sound waves being sent from the outer ear.
Conductive hearing loss


Unilateral sensorineural hearing loss

Sensorineural hearing loss, on the other hand, occurs when there is damage to the hair cells in the cochlea (found in the inner ear) or to the nerve pathways which lead from the inner ear to the brain. A person may also suffer from mixed hearing loss, which is a combination of both conductive and sensorineural hearing loss.
