Audiometry and the new-born
Insights
Early detection of hearing defects presents both benefits and drawbacks. Optimal timing for hearing examinations is between 6-9 months, with newborn screening generally discouraged despite new technologies.
Area of Science:
- Pediatrics
- Audiology
- Developmental Pediatrics
Background:
- Early detection of hearing loss is crucial for child development.
- Current practices and emerging technologies influence newborn hearing screening.
- The balance between benefits and drawbacks of early hearing defect detection is a key consideration.
Purpose of the Study:
- To evaluate the advantages and disadvantages of early hearing defect detection in infants.
- To determine the optimal age for hearing defect examinations.
- To provide recommendations on newborn hearing screening practices.
Main Methods:
- Review of existing literature on infant hearing screening.
- Analysis of the developmental timeline for hearing defect manifestation.
- Consideration of factors influencing the efficacy and practicality of screening methods.
Main Results:
- The benefits and drawbacks of early hearing defect detection are not balanced until 6-9 months of age.
- Compelling reasons, such as parental anxiety, may justify earlier examinations.
- Newborn screening, despite technological advancements and hospital birth rates, is advised against.
Conclusions:
- Routine newborn hearing screening should be strongly discouraged.
- Hearing examinations are best conducted between 6-9 months of age.
- Selective early screening is recommended only under specific circumstances like parental concern.
Abstract:
The early detection of hearing defects has not only advantages but also disadvantages. It is not until the child is 6-9 months old that these begin to balance out. Early examination should be done only when there are compelling reasons, e.g. parental anxiety. The screening of the new-born baby, however attractive it may be as a result of new techniques and the fact that, in some countries many children are born in hospital, must be strongly discouraged.
