Insights
Preventing congenital hearing loss in children is possible by addressing risk factors during pregnancy and childbirth. Early identification and intervention, alongside genetic counseling, are crucial for reducing the incidence of severe congenital deafness.
Area of Science:
- Pediatric Audiology
- Genetics
- Public Health
Context:
- Investigates the multifactorial etiology of severe congenital bilateral profound deafness in children.
- Analyzes a cohort of 177 deaf children, 135 normal-hearing siblings, and 70 deaf relatives.
Purpose:
- To identify key etiological factors contributing to congenital hearing loss.
- To explore the potential for prevention through risk factor mitigation and genetic consultation.
Summary:
- Identified pathological factors during pregnancy (20 cases) and perinatal/neonatal issues (32 cases) as significant contributors to congenital deafness.
- Highlights that eliminating identified risk factors could theoretically prevent a substantial proportion of congenital hearing deficits.
Impact:
- Emphasizes the critical role of geneticist collaboration in preventing hereditary deafness.
- Suggests that targeted interventions can significantly reduce the prevalence of childhood hearing impairment.
Abstract:
The author analyzes factors which may play a part in the aetiology of severe congenital bilateral perception deafness--practically complete deafness--in children. The group of patients comprises 177 deaf children, 135 siblings with normal hearing and 70 deaf parents and other relatives. Pathological factors during pregnancy were detected in 20, perinatal and neonatal pathology in 32 instances. If the anamnestically detected risk factors in the aetiology of the hearing deficit played a part, theoretically by their elimination a considerable proportion of the congenital hearing affections in children could be prevented. The author emphasizes the necessity of collaboration with a geneticist in the prevention of inborn hereditary deafness.
