About 3 in every 1000 children are born with less severe hearing loss. One in 10 chance of birth with less severe hearing deficiency, and more who have normal hearing at birth develop less experienced hearing before adulthood. Failure to recognize and treat hearing deficiency can affect the ability to speak and understand language seriously. Such damage can lead to failure at school, ridiculed by peers, ostracized, and emotional difficulties.
CAUSE
Genetic damage is the most common cause of hearing loss in newborns. Ear infections, including otitis media, is the most common cause of hearing loss in older children, during the buildup of earwax. Other cases in older children is head trauma, noise (including loud music), the use of aminoglycosides antibiotics (such as gentamicin), or thiazide diuretics, certain viral infections (eg, thyroid disease), tumors or trauma that damages nerves associated with auditory, injuries due to pencil or other foreign objects that enter in the ear, and its rare, autoimmune disease.
Risk Factors
Risk factors for hearing loss in children:
- Newborns
- low birth weight (especially less from 3.3 pounds).
- low Apgar rate (lower than 5 at 1 minute or lower than 7 at 5 minutes).
- low blood oxygen or seizures caused by obstructed labor.
- rubella infection, syphilis, herpes, cytomegalovirus, or Toxoplasma before birth.
- Abnormalities of the skull or face, especially those associated with the outer ear and ear canal.
- High levels of bilirubin in the blood.
Bacterial meningitis - .
Infection - blood vessels (sepsis)
- Using a ventilator with time is too long.
- Drugs (aminoglycosides antibiotics, some diuretics)
History - health hearing loss at an early age in the parents or relatives.
Older children
Same with all the points above, plus:- severe wounds on the head with a skull fracture or loss of consciousness.
- chronic otitis media with cholesteatoma.
- Several neurological disorders, such as neurofibromatosis and neurodegenerative disorders.
Affected - noise
- hole in the eardrum due to infection or serious injury.
- severe wounds on the head with a skull fracture or loss of consciousness.
- low birth weight (especially less from 3.3 pounds).
SYMPTOMS
Parents can expect less severe hearing loss if the child does not react to sound or if the child has difficulty speaking or replying to chat. Hearing loss are not severe can be subtle and cause symptoms that are misinterpreted by parents or doctors. Children who ignore their parents or others who speak with them awhile, but not every time, probably do so because of lack of hearing is.
Children who speak and hear well at home but not in school may experience mild or moderate hearing less of where the problem is only in the middle of the noise in the classroom. In general, children are developing well dlam one situation but have social difficulties, behavioral, language and learning significantly in different situations should dilkukan screening for hearing deficiency.
Diagnosis
Because hearing plays an important role in the development of a child, most doctors recommend that all newborns be tested for hearing less at age 3 months. These tests are regulated by governments in many countries.
Screening is usually done in two parts. First, the child is tested for the echoes produced by healthy ears in response to a soft clicking sound produced by handheld devices (evoked otoacoustic emissions testing). If the test is the increased responsiveness of the hearing of a child, a second test measures the electrical signals from the brain in response to sound (brain stem response test associated with hearing)). ABR is not painful and is usually done when the child is sleeping; it can be performed on children at any age. If the results of the ABR is abnormal, the test is repeated in 1 month. If hearing loss is detected, the child is likely adapted to hearing aids and could benefit from placement on the education of children who are less devoted hearing.
Several different tools are used to diagnose hearing less on older children. One of them involves asking a series of questions to detect developmental delays in children, or to suspect the child's attention on the development of language and speech. the child's ear can also be examined for abnormalities. Children aged between 6 months and 2 years studied the possibility for their reaction to various sounds. In addition, the reaction of the eardrum to the sound frequency range (tympanometry) can indicate if there is fluid in the middle ear. After age 2, children usually can show that they hear and understand how to talk with a few simple commands, and they can be tested for reaction to sounds using hearing aids.
TREATMENT
Some causes of hearing loss can be treated so that the child could get hearing back. For example, ear infections can be treated with antibiotics or surgery, ear wax can be manually removed or destroyed with ear drops, and cholesteatoma can be removed with surgery. Very often, however, causes of hearing loss in children can not be restored, and the treatment involves the use of hearing aids to replace the shortage as much as possible.
Hearing aids are available for children aged 2 months. Children with mild or simple lack of hearing that occurs only in the classroom can also respond well to a radio system that leads the teacher's voice directly into a set of loudspeakers, hearing aids, or ear loudspeakers. Planting cochlear (a tool that is placed on the inner ear to stimulate auditory nerves associated with the electric current that responds to sound) is used for children with severe acute hearing.
Feeling proud to have grown in recent years among the deaf community about the richness of their culture and alternative forms of the communication. Most people opposed to the aggressive treatment of hearing loss as a reason to reject the children get an opportunity in their communities. Families who wish to consider this approach should discuss this with their doctor.
