The impact of hearing impairment: a global health problem

The assessment of hearing organ of school children in Upper Silesia region

“…Changeable or asymmetric hearing loss in small children results in long-term consequences, manifested in difficulties to locate the sound (disturbances of binaural hearing), despite the fact that hearing returned to normal condition [26,27]. Bess presented similar conclusions in reference to children with MSHL, in which as many as 37% repeated a year at school, most of them had language problems, as well as emotional difficulties (the study group consisted of 1218 children) [18].…”

Detection of Epidermal Thickening inGJB2Carriers with Epidermal US

“…Congenital hearing loss represents an important public health issue because it implies either lifelong disability or expensive interventions and rehabilitation programs (11). Nonsyndromic hearing impairment is the most prevalent type worldwide, with most cases resulting from recessive mutations in the GJB2 gene, in which carriers are asymptomatic.…”

Cochlear Implants in Children: A Review

“…By the late 1990's, although language outcomes for children with cochlear implants had improved compared to those for children with similar degrees of loss using hearing aids, on average, children with cochlear implants were still demonstrating language growth rates of only 50-60% of the rate of children with normal hearing (Blamey et al, 2001a;Davis & Hind, 1999;Geers, 2002;Ramkalawan & Davis, 1992;Wake et al, 2004). Given the fact that these children were already delayed in their language development by the amount of time it had taken for diagnosis and implantation to occur, this slower rate of growth meant that by the t i m e t h e y w e r e o f s c h o o l a g e , m a n y c h i l d ren were delayed by at least 1 year, and approximately half had a severe language delay (ie.…”

“…Many children with severe-profound hearing loss, including those with cochlear implants, have 4 to 5 year delays in spoken language development by the time they enter secondary school (Blamey et al, 2001a;Dahl et al, 2003;Davis & Hind, 1999;Ramkalawan & Davis, 1992;Sarant et al, 2009). Generally, the greater the degree of hearing loss, the larger the language delay (Boothroyd et al, 1991).…”
