Hearing loss in neonates and infants

Area of Science:

• Pediatrics
• Audiology
• Genetics

Background:

• Congenital hearing loss is the most common sensory deficit in newborns, affecting 1.5 per 1,000 live births.
• Genetic factors account for up to 80% of cases, with congenital cytomegalovirus being a key environmental cause.
• Untreated hearing loss significantly impacts infant development and incurs socioeconomic burdens.

Purpose of the Study:

• To highlight the critical importance of early hearing detection and intervention in neonates and infants.
• To review current and emerging diagnostic and therapeutic strategies for congenital hearing loss.
• To emphasize the role of advanced technologies in managing hearing impairments.

Main Methods:

• Utilized automated auditory brainstem response and automated otoacoustic emission for newborn hearing screening.
• Reviewed current auditory rehabilitation technologies, including advanced cochlear implantation.
• Examined the progress in genetic diagnostic technologies and potential gene therapies.

Main Results:

• Newborn hearing screening programs facilitate early detection and management of hearing loss.
• Modern cochlear implantation effectively treats a wide range of hearing loss severities.
• Genetic diagnostics and gene therapy represent promising future avenues for treatment.

Conclusions:

• Early identification and intervention are crucial for optimal language and communication development in infants with hearing loss.
• Technological advancements in diagnostics and treatment, particularly gene therapy, offer hope for improved outcomes.
• A multidisciplinary approach combining screening, rehabilitation, and genetic insights is essential for managing congenital hearing loss.
