Area of Science:

  • Pediatrics
  • Otolaryngology
  • Genetics

Background:

  • Childhood deafness is a significant disability with diverse etiologies.
  • Identifying the cause of hearing loss is essential for appropriate management and intervention.
  • A substantial percentage of childhood deafness cases have unknown origins.

Purpose of the Study:

  • To investigate the aetiology of hearing disorder in a cohort of children with deafness.
  • To determine the proportion of deafness cases attributable to specific factors like meningitis and perinatal pathology.
  • To highlight the impact of early detection on reducing the percentage of unknown deafness causes.

Main Methods:

  • A prospective study examining 155 children with childhood deafness over 4 years.
  • Data collection included medical history, clinical examination, and diagnostic assessments.
  • Analysis focused on identifying the underlying causes of hearing loss.

Main Results:

  • Meningitis was identified as the cause in 13% (21/155) of cases.
  • Perinatal pathology accounted for 22% (34/155) of childhood deafness.
  • The aetiology remained unknown in 28.4% (44/155) of the children studied.
  • Only 19% (30/155) of children were diagnosed with hearing loss by age 2.

Conclusions:

  • Early detection of deafness, through high-risk infant screening and healthcare provider education, is vital.
  • Timely diagnosis can significantly reduce the proportion of unknown deafness aetiologies.
  • Implementing early screening programs is recommended to improve outcomes for children with hearing loss.
