Abstract

Hearing loss in children has multiple aetiologies, making diagnosis based on clinical signs and symptoms challenging. Hearing loss at a young age will affect a child’s cognitive and linguistic development, resulting in loss of quality of life and possible behavioural and social problems. It is important to screen before the end of the neonatal period, 1 month of age, as well as a follow up at 3 months, due to multiple progressive hearing loss causes. Congenital, delayed onset or acquired hearing loss in children is classified into timing of onset of symptoms. Genetic, non-syndromic, syndromic, and infectious causes are the most common aetiologies. Further characterization of hearing loss based on the mechanism of the auditory system involved yields conductive, sensorineural, and mixed hearing loss. The organisation of different sound frequencies in the auditory cortex ends at 2 years of age and indicates an important window period for intervention. The evidence of benefit from early application of hearing aids and cochlear implants supports the argument to treat and rehabilitate children early.

Abstract (croatian)

Gubitak sluha kod djece ima višestruku etiologiju, što otežava dijagnosticiranje na temelju kliničkih znakova i simptoma. Gubitak sluha u mlađoj dobi utjecat će na djetetov kognitivni i jezični razvoj, što će rezultirati gubitkom kvalitete života i mogućim socijalnim problemima te problemima ponašanja. Važno je pregledati dijete prije kraja neonatalnog perioda, mjesec dana starosti djeteta, te ponoviti pregled sa tri mjeseca života, zbog višestrukih progresivnih uzroka gubitka sluha. Kongenitalni, postepeni ili stečeni gubitak sluha u djece klasificira se obzirom na početak simptoma. Genetski, nesindromski, sindromski i zarazni uzroci najčešće su etiologije. Daljnja karakterizacija gubitka sluha temeljena na organizaciji slušnog sustava otkriva provodni, senzorineuralni i mješoviti gubitak sluha. Sazrijevanje različitih zvučnih frekvencija u slušnom korteksu završava u dobi od 2 godine i ukazuje na važno vremensko razdoblje za intervenciju. Dokazi o koristi rane primjene slušnih pomagala i umjetnih pužnica jasno pokazuju da je liječenje i rehabilitacija potrebna prije nego što bude prekasno.
