MUST TAKE NOTICE.
Any individual should know that a child or adult would be labeled disable, if they suffered with severe deafness.
It don’t necessarily have to be loss of limb or some form of a mental condition that hinders one from functioning day-by-day in society.
This is why routine hearing exams are so important if you suspect something is not right as your child develops.
Because as you know, raising a hearing impaired child, could be a daunting task.
If your child is under age two, or is uncooperative during his or her examination, the child may be given one of two available screening test, which are the same test used for newborn disability screening.
They are painless, take just five to ten minutes. and can be performed while your child is sleeping or lying still. They are:
THE AUDITORY BRAIN-STEM:
This is a response test which measures how the brain responds to sound.
Clicks or tones are played into the baby’s ears through soft earphones, and electrodes placed on the baby’s head measure the brain’s response.
This allows the doctor to test your child without having to rely on his or her cooperation.
This test measure sound waves produced in your child’s middle ear. A tiny probe is placed just inside the baby’s ear canal, which then measures the response when clicks or tones are played into the baby’s ear.
These tests may not be available in your immediate area, but the consequences of an undiagnosed condition are so serious that your doctor may advise you to travel to where one of them can be done.
Certainly, if these tests indicate that your baby may have a problem, your doctor should recommend a more thorough sound evaluation as soon as possible to confirm whether your child’s hearing is impaired.
YOUR CHILD’S TREATMENT
Treating a deaf situation will depend on its cause. If it is a mild conductive issue due to fluid in the middle ear, the doctor may simply recommend that your child be retested in a few weeks to see whether the fluid has cleared by itself.
Medication such as antihistamines, decongestants, or antibiotics are ineffective in clearing up middle ear fluid.
If there is no improvement in the hearing over a three-month period, and there is still fluid behind the eardrum, the doctor may recommend referral to the ENT specialist.
If the fluid persists and there is sufficient (even though temporary) conductive hearing impairment from the fluid, the specialist may recommend draining the fluid through ventilating tubes.
These are surgically inserted through the eardrum.
This is a minor operation and takes only a few minutes, but your child must receive a general anesthetic for it to be done properly, so he usually will spend part of the day in a hospital or an outpatient surgery center.
Even with the tubes in place, future infections can occur, but the tubes help reduce the amount of fluid and decrease your child’s risk of repeated infection. They will also improve his or her hearing.
CONDUCTIVE HEARING LOSS
If a conductive hearing loss is due to a malformation of the outer or middle ear, an aid may restore hearing to normal or near-normal levels. However, an aid will work only when it’s being worn.
You must make sure it is on and functioning at all times, particularly in a very young child. Reconstructive surgery may be considered when the child is older.
SENSORINEURAL HEARING LOSS
Hearing aids will not restore hearing completely to those with sensorineural hearing loss (also called nerve deafness, which is caused by an abnormality of the inner ear or the nerves that carry sound messages from the inner ear to the brain).
The loss can be present at birth or occur shortly thereafter. If there is a family history of deafness, the cause is likely to be inherited (genetic).
If the mother has rubella (German Measles), cytomegalovirus (CMV), or another infectious illness that affects hearing during pregnancy, the fetus could have been infected and may lose their hearing as a result.
The problem also may be due to a malformation of the inner ear.
Most often the cause of severe sensorineural hearing loss is inherited.
Still, in most cases, no other family member on either side will have hearing loss because each parent is only a carrier for a hearing loss gene.
This is called an “autosomal recessive pattern,” rather than “dominant” where it would be expected that other family members on one side would have hearing loss.
Future brothers and sisters of the child have an increased risk of being hearing impaired, and the family should seek genetic counseling if the hearing loss is determined to be inherited.
Hearing loss must be diagnosed as soon as possible, so that your child isn’t delayed in learning language – a process that begins the day he or she is born.
The American Academy of Pediatrics recommends that before a newborn infant goes home from the hospital, she needs to undergo a hearing screening.
GENETIC DISEASES THAT CAUSE DEAFNESS
There are a number of diseases that can be passed down in families that will result in hearing loss. These include Paget’s disease. Alport’s disease, Cogan’s syndrome and Pendred’s synrome.
Alport’s Disease – This genetic disease causes kidney inflammation in childhood, followed by a sensorineural hearing impairment in young adulthood and eye problems later in life.
(It’s more common among men than women).
Cogan’s Syndrome – This inflammation of the cornea, which occurs for no known reason, can also damage new bone formation around the round window and destroy the organ of Corti and cochlear nerve cells.
It can lead to vertigo, tinnitus and severe sensorineural hearing loss.
Pendred Syndrome – An inherited condition that causes deafness (usually at birth) and development of goiter (enlarged thyroid) in childhood.
People with the syndrome have different degree or hearing loss, but it is severe for more than half of them.
The syndrome is probably the most common form of deafness that appears with another condition (in this case, goiter).
Scientist are not sure what causes the problem, but recent research suggests that Pendred’s syndrome may be related to a gene mutation that produces a defective form of the protein pendrin.
New research suggests that pendrin may be associated with the transportation of iodide in the thyroid.
For those with Pendred syndrome, a defect in iodide transport may cause the thyroid to enlarge, although the gland will usually continue to function normally.
