Hearing Loss In Children

Common causes of hearing loss are genetic defects in newborns and ear infections and ear wax in children. Many cases are detected by screening, but hearing loss should be suspected when the children do not respond to noise or have a delayed language development. The diagnosis is usually done by electro-diagnostic tests (evoked otoacoustic emission testing and auditory brainstem response) in neonates and by clinical examination and tympanometry in children. The treatment of irreversible hearing loss may include a hearing aid or cochlear implant.

Common causes of hearing loss are genetic defects in newborns and ear infections and ear wax in children. Many cases are detected by screening, but hearing loss should be suspected when the children do not respond to noise or have a delayed language development. The diagnosis is usually done by electro-diagnostic tests (evoked otoacoustic emission testing and auditory brainstem response) in neonates and by clinical examination and tympanometry in children. The treatment of irreversible hearing loss may include a hearing aid or cochlear implant. (Hearing loss.) In the US, a permanent hearing loss in childhood at 1.1 / 1,000 infants screened is detected. On average, 1.9% of children reported “difficulty hearing.” Hearing loss is slightly more common in boys than in girls; the average ratio of male: female is 1.24: 1st Etiology The most common cause in newborns is a genetic defect. The most common causes in infants and children are Cerumenansammlungen and middle ear effusions, including otitis media with effusion. Other causes in older children include head injuries, noise loud (including loud music), the use of ototoxic drugs (eg. As aminoglycosides, thiazides), viral infections (eg. As mumps), tumors or injuries that affect the auditory nerve, foreign body rare in the ear canal and autoimmune diseases. Low birth weight (. For example, <1.5 kg) Apgar number <5 (1 min) or 7 (5 min) hypoxemia or seizures resulting from a heavy confinement Prenatal: Among the risk factors for hearing loss in newborns include the following infection with rubella, syphilis, herpes, cytomegalovirus or toxoplasmosis Craniofacial anomalies, particularly those affecting the pinna hyperbilirubinemia sepsis or meningitis ventilator dependency use of ototoxic medications family history of early hearing loss, the risk factors for hearing loss in children include those for newborns, plus the following: traumatic skull fracture or loss of consciousness cholesteatoma Neurodegenerative diseases, including neurofibromatosis L ärmexposition eardrum symptoms and complaints If the hearing loss is severe, the infant or child may not respond to noise or has a delayed language or a delayed speech understanding. If the hearing loss is less severe, the child may ignore sometimes people who talk to them. The children eventually developing well under certain circumstances, but have problems among others. Because the background noise can make in a classroom speech discrimination, for example, difficult, the child has possibly only in school hearing difficulties. Failure to recognize the limitation and treat can affect speech understanding and language usage severe. The restriction can lead to school failure, teasing, social isolation and emotional difficulties. Diagnosis Electrical Diagnostic tests (newborns) Clinical examination and tympanometry (children) The screening of all infants before the age of 3 months is often recommended and is required by law in most US states. The initial screening test is the evoked otoacoustic emission test, are produced at the gentle clicks with a hand-held device. If the results are abnormal or inconclusive, the auditory brainstem responses are tested, what can be done in sleep; abnormal results should be confirmed with repeat testing after 1 month. In children, other methods can be used. Language development and general development are assessed clinically. The ears are examined and the eardrum movement is tested in response to different frequencies to check for middle ear effusion. In children aged 6 months to 2 years, the response to noise is tested. Aged> 2 years, the ability to follow simple auditory commands, be assessed as well as the reactions to sounds with headphones. A central auditory processing evaluation (hearing loss: tests) can> 7 years but can not seem to understand that in children without neurocognitive deficits to hear, be used. Imaging is often indicated to identify the etiology and guide the prognosis. In most cases, including when the neurological examination abnormal, word recognition bad and / or hearing loss is asymmetric, a gadolinium MRI is performed. If bone abnormalities are suspected, a CT is performed. Therapy hearing aids or cochlear implants for hearing loss irreversible Sometimes teaching a non-auditory language Reversible causes are treated. If the hearing loss is irreversible, usually a hearing aid can be used (hearing loss: hearing aids). They are available for both infants and children. If the hearing loss is mild or moderate, or only one ear is concerned, a hearing aid or a headset can be used. In the classroom, an FM Heard Rainer can be used. With an FM Heard Rainer the teacher speaks into a microphone that sends signals to a hearing in the unaffected ear. If the hearing loss is severe enough that it can not be treated with hearing aids, Cochlear Implants is needed eventually. The children also may need a therapy to support their language development, such as learning a visually-based sign language (hearing loss: treatment of hearing loss in children). Key points Common causes of hearing loss are genetic defects (neonatal) and Cerumenakkumulation and middle ear infusions (in children). Hearing loss is suspected, if the reaction of a child to sounds or the development of speech and language is abnormal. Infants are screened for hearing loss, starting with the evoked otoacoustic emission testing. Children are diagnosed based on the results of clinical examination and tympanometry. Irreversible hearing loss is treated as needed with a hearing aid or cochlear implant, and with language support (z. B. learning sign language).
