Abstract
Definitive causes of sensorineural deafness can now be found in many children. Most cases are due to cochlear dysfunction.
Key Points
- It is now possible to find the cause of sensorineural deafness in many children.
- History, examination, family hearing studies and interview enable the exclusion, or establishment, of autosomal dominant and syndromic deafness.
- High resolution CT scanning, MRI, ECG and laboratory tests (blood and genetic screening) may determine environmental, nonsyndromic autosomal recessive and mitochondrial causes of deafness.
- A very small group of deaf children will have a nonobvious environmental determinant.
