Universal neonatal hearing screening (UNHS), which is part of early hearing detection and intervention (EHDI) programmes, refer to those services aimed at screening hearing of all newborns, regardless of the presence of a risk factor for hearing loss. UNHS is the first step in the EHDI program which indicates whether a newborn requires further ...
Congenital hearing loss is a hearing loss present at birth. It can include hereditary hearing loss or hearing loss due to other factors present either in-utero (prenatal) or at the time of birth. It can include hereditary hearing loss or hearing loss due to other factors present either in-utero (prenatal) or at the time of birth.
Risk factors for hearing loss are provided below in the table titled, "Risk Factors For Hearing Loss in Newborns (JCIH, 2000 [14])." Targeted screening has been shown to identify approximately 50% of babies with moderate to profound hearing loss (Vohr et al., 2000; [24] Watkin et al., 1991 [25]).
Story at a glance More than 1 billion young people around the world could be at risk of hearing loss. Researchers note limiting exposure to loud noise is one way young adults can lower their risk.
Hearing loss due to chemicals starts in the high-frequency range and is irreversible. It damages the cochlea with lesions and degrades central portions of the auditory system. [45] For some ototoxic chemical exposures, particularly styrene, [46] the risk of hearing loss can be higher than being exposed to noise alone.
Prelingual hearing loss can be considered congenital, present at birth, or acquired, occurring after birth before the age of one. Congenital hearing loss can be a result of maternal factors (rubella, cytomegalovirus, or herpes simplex virus, syphilis, diabetes), infections, toxicity (pharmaceutical drugs, alcohol, other drugs), asphyxia, trauma, low birth weight, prematurity, jaundice, and ...
Prevalence in the population is relatively unknown. Neonates with high risk factors for hearing loss have a prevalence of up to 40% (Vignesh, Jaya, & Muraleedharan 2016). These high-risk factors are: hypoxia, low birth weight, premature birth, hyperbilirubinemia, jaundice, and aminoglycoside antibiotic treatments (NIDCD, 2018).
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
