Congenital deafness (hearing loss): causes of hearing loss in children
What causes congenital hearing loss?
Hearing loss gradual hearing loss, at which there is a violation of the sensations of sound waves and noise as well as dysfunction of speech communication. There are several types of hearing loss in which the degree of disease is characterized as from the smallest, almost imperceptible change of hearing acuity, and the severe damage the hearing aid, up to deafness.
For diagnosing inflammation and comprehensive examination, you must visit a doctor-otolaryngologist and an otoneurology. Only with their help it is possible to establish a classification and the type of inflammation and treatment.
About hearing loss
Congenital hearing loss occurs infrequently. For its diagnosis it is necessary to pass a comprehensive examination, including otoscopy, audiometry and other tests to help determine the classification and stage of the disease.
Depending on the nature of the disease, the patient assigned to medical therapy and special exercises, including massage or hearing and individual hearing aid.
However, in some cases, the patient can help tympanoplasty or the introduction of implants.
But first let us examine the causes of congenital deafness. According to Russian sources, only one infant of the thousands of suffers from a congenital hearing loss.
Inflammation and persistent hearing loss occurs due to abnormalities in the development inside of the mother or due to pathological changes of the structure of the middle ear. Another cause be a neurological disorder.
Although there is another opinion, why formed congenital deafness in children — many experts believe that half of the children have hearing problems, have a genetic predisposition. There is even some scheme by which the inheritance is divided into shape.
Genetic forms of hearing loss are significantly different from acquired diseases and hearing loss. Therefore, to recognize the congenital form is required even when planning the baby. So, there is otologic, audiological and physical study of the health of future parents that investigates human DNA and conducted testing for hearing loss.
When mutations in the genes responsible for hearing the baby with a probability of 99 percent is formed of congenital hearing loss or even deafness.
Causes of congenital deafness in the newborn
Congenital hearing loss and persistent reduction of hearing in babies is often transmitted in an autosomal recessive manner, and slightly less dominant type.
When diagnosing these data, the baby is formed by progressive deafness and pathological changes in the structure of the ear organ.
In this case, violation of perception of sound waves can be noticed at the first months of baby’s life. Often a child is diagnosed not unilateral, but bilateral inflammation and hearing loss.
70 percent of children this form of hearing loss occurs in isolation, but in other situations diagnosing problems with the perception of sounds is due to genetic predisposition.
Inflammation and education of hearing loss in babies occurs because of several reasons. Most often hearing problems arise during fetal development. If during pregnancy expectant mother suffered rubella, measles, flu or colds, tuberculosis, syphilis and other dangerous inflammation, the baby will be a gathering in formation.
These diseases always lead to a violation of the hearing aid and the problems in the middle ear that causes congenital hearing loss. In this case, children may be a mild form of inflammation, and to develop the complete lack of audibility of sound waves.
Inflammation in pregnancy
Furthermore, causes of congenital hearing loss can occur due to chronic inflammation in the mother. Such diseases include:
- diabetes mellitus;
- pathological inflammation that produces excessive secretion of hormones – hyperthyroidism;
- reduced hemoglobin in the blood;
In addition, if a pregnant woman during pregnancy, taking antibiotics or other ototoxic drugs on the basis of neomycin or streptomycin, the fetus can develop abnormalities.
Another common reason to become a work in dangerous places, addiction to alcohol and cigarettes, and drugs.
Rare, but still common reason is premature birth of the baby. In this case, hearing problems are diagnosed at twenty-five percent of kids.
Hearing loss can be not only innate, but acquired in childhood. At this time, it is important to monitor the hygiene of a baby’s ears and explore ear canal on the subject of cerumen and the presence of foreign objects every day.
Also, don’t forget to undergo routine checkups at the ENT, as the inflammatory processes in the ears and the first signs of the formation of otitis media or other diseases, an experienced doctor can notice the outside of the vehicle.
In running condition and the inflammation of the large the likelihood of hearing loss.
Prevention and forecasts
To see the first signs of hearing loss the baby yourself. If the child does not respond to name, does not react to loud sounds and does not turn his head on the sharp screams back the baby obvious hearing problems.
Early identification of deafness and hearing loss will help in treatment and favorable outcome. Otherwise, there may be serious problems with verbal communication, overall development, and socialization in society.
With early treatment, almost eighty percent, the Outlook is positive. Treatment of congenital hearing loss in the clinic, and for the prevention of hearing problems, during pregnancy it is necessary to fence themselves from viral inflammation, not to be in crowded places during the development of respiratory disease, eat more vegetables and fruits.
And you need time to get vaccinated, which will ensure the safety of the ENT diseases. In addition, avoid taking antibiotics and other harmful drugs, strongly reduce the immune system.
