Hearing loss is a decrease or loss of hearing. The fact that this problem appears early in life is something we should take into account the subsequent complications that can bring. Today we will see the hearing loss in infants.
The appearance of a bilateral hearing loss during early childhood will lead to a lowering of information that negatively impact on various areas of learning and further development. These changes will be much more serious when deafness put in place at an earlier age.
The causes of deafness can be varied, for example during childhood hearing loss is usually temporary, sometimes appears after colds or due to a buildup of fluid behind the tympanic membrane , non-suppurative chronic otitis media, or otitis media with effusion.
The aparicción of hearing loss in infants may also have to do with the presence of damage in the outer or inner ear, middle or the auditory nerve. You also can not forget the prenatal causes, such as infection during pregnancy, Down syndrome or a genetic defect.
Hearing problems during early childhood can also be produced by the occurrence of problems during delivery, these problems are mainly due to lack of oxygen at birth. Which are also children born preterm may lead to hearing problems.
Among the post-natal causes that can lead to hearing loss problems, we must contemplate diseases such as meningitis , viral infections, head trauma, and the intake of certain medications that can lead to the occurrence of these problems.
Based on the location and functional mechanism of hearing loss in infants, we can classify in conductive hearing loss, also known as driving perception hearing loss , also known as sensorineural, and mixed hearing loss.
Among the risk factors that we must consider in this disease, with respect to the newborn is necessary to look at things like family history of deafness or intrauterine infections such as cytomegalovirus, rubella, syphilis, toxoplasmosis or herpes.
Also make risk factors for the onset of hearing loss the malformations of the head and neck , severe hyperbilirubinemia, prematurity and weight below 1500 g, neonatal meningitis or taking ototoxic drugs during pregnancy.
To complete all the risk factors that must be considered in relation to the onset of hearing loss in infants, taking over the newborn, we should note the APGAR score low birth , admission to neonatal ICU and genetic syndromes associated with deafness.
Although we are focusing on the appearance of this hearing problem in babies , do not want to leave out the potential risk factors to consider with respect to the older child. Among them or recurrent otitis media with effusion for more than three months.
Other risk factors that could cause the onset of hearing loss in older children are severe traumatic brain injuries, delayed language acquisition, meningitis and the use of ototoxic drugs .
