Unilateral hearing loss refers to hearing loss in only one ear, with normal hearing in the opposite ear. Unilateral hearing loss can occur prior to or anytime after birth and can vary in degree from mild to profound. A type of unilateral hearing loss in which one ear is normal and the poor ear is “unusable” is called single-sided deafness.
What causes unilateral hearing loss?
What are the symptoms?
Symptoms of a unilateral hearing loss may include:
- Difficulty finding where sounds are coming from (localization)
- Difficulty hearing from the affected side or in noisy environments
- An “echo” quality to sounds in the case of a sudden unilateral hearing loss
- Tinnitus in the affected ear
How is it treated?
Treatment for unilateral hearing loss will depend on what the cause of the hearing loss is.
If no medical or surgical intervention options are appropriate, there are several rehabilitation options available to manage unilateral hearing loss. These options can be discussed with you by an Audiologist and may include a conventional hearing aid, CROS hearing aid, bone-anchored hearing aid, SoundBite hearing system, FM system, or a cochlear implant.
