What is unilateral hearing loss?
When hearing is impaired in only one ear, it is called a unilateral hearing loss. The following are some reasons a person may have a unilateral hearing loss:
- Ear infections
- Cranial radiation
- A tumor pressing on or near the auditory (hearing) nerve
- Surgery or swelling close to the auditory nerve
- Being hit on the head
- A hole in the ear drum
- Some children are born with a hearing loss for unknown reasons
Are all unilateral hearing losses permanent?
Three general types of hearing loss exist. A hearing loss can be conductive. This type of hearing loss involves the outer or middle ear. It does not involve the inner ear or auditory nerve. It is usually not permanent. A hearing loss can also be sensorineural. This means that it does involve the inner ear and/or the auditory nerve.
This type of hearing loss is usually permanent. It may be reversible if the hearing loss is caused by a tumor or swelling in the head or brain. A hearing loss can also be mixed—both conductive and sensorineural.
What can be done to help?
Most children with unilateral hearing loss do not have problems with their speech or language. Most of the time they do not have problems understanding others, but sometimes understanding is more difficult. One situation where it would be harder to understand is when the child is in a noisy area, such as a cafeteria. Parents and teachers can help by following the suggestions below.
Suggestions for Home and School
- Get the child’s attention before speaking.
- Use words the child knows and use simple sentences.
- If you say something the child does not understand, do not repeat the same thing. Try saying it in a different way.
- Use facial expressions and gestures to add meaning to the words you are saying.
- At school, the child should sit in the front of the class. The “good” ear should be close to the teacher and away from distracting noises such as a hallway or air conditioner.
- Minimize distracting noise inside and outside the classroom.
- Routinely check the child’s speech, language and academic progress.
- Consider using a personal FM system in school to help the child hear the teacher's voice over other noises.
- The child may have trouble localizing sounds. This means that the child may not be able to quickly determine where a sound is coming from.
- Learning bicycle and traffic safety rules is very important because it may be harder for the child to hear warning sounds.
- Protect the hearing in the “good” ear:
- Avoid loud noises. If the child is going to be in loud noise, earplugs or ear muffs should be worn.
- See a doctor if you think your child has an ear infection.
- Do not put anything in the ear unless your doctor tells you to do so.
- Be aware that some prescription and over the counter medicines may affect hearing. These are called ototoxic medicines. Children with unilateral hearing loss should have their hearing checked often if they are on an ototoxic medicine. Ask your doctor or pharmacist if you are not sure if a medicine your child is taking is ototoxic.
- The doctors your child sees in the future should be told about the hearing loss.
- Have a hearing test once a year by a certified audiologist. If you think that there has been a change in hearing (better or worse), the child’s hearing should be tested as soon as possible.
