Hearing Loss in Children

Hearing Loss in children

Hearing is important for children to develop speech and language skills as they grow. In previous time hearing loss in  children undetected until the child was around two years old, when it became obvious that the child wasn’t talking yet.

Children learn communication by copying the sounds they hear. If a child has a hearing loss that is undetected and untreated, they can miss much of the speech and language around them. This results in delayed speech development, social problems and academic difficulties.

Hearing loss, in varying degrees, affects two children in every 100 children under the age of Eighteen. Unfortunately, there are very few hearing losses that cannot be helped with modern technology.

Types of Children Hearing Loss

Hearing loss in children can be present at birth (congenital) or acquired after birth. The two primary types of hearing loss are:

  • Sensorineural hearing loss – This type of hearing loss is related to damage or a defect in the inner ear or in the neural connection to the brain. Sensorineural hearing loss can be caused by congenital factors or can occur after birth.
  • Conductive hearing loss – A reduction of sound being sent to the inner ear caused by a problem in the outer or middle ear. Conductive is the most common type of hearing loss in children and is usually acquired. In a minority of cases, this type of hearing loss is congenital.

Hearing loss can also be a mix of both of these types, affecting both the inner ear and outer/middle ear.

Congenital hearing loss

This hearing loss occurs at birth. There are many causes of congenital hearing loss though they are not always easily identified. There are both non-genetic and genetic factors that might cause hearing loss.

  • Birth complications
  • Premature birth.
  • A nervous system or brain disorder.
  • The mother had an infection during pregnancy.
  • Maternal diabetes.
  • Drug or alcohol abuse by the mother or smoking during pregnancy.

Acquired hearing loss

Children also are affected by the acquired hearing loss, meaning it occurs after birth. There are various causes of acquired hearing loss, including:

  • A serious head injury
  • Infections like meningitis, measles, mumps or a whooping cough
  • Taking ototoxic medications
  • A perforated eardrum
  • Exposure to loud noise, causing noise-induced hearing loss
  • Untreated or frequent otitis media (ear infections)
  • Exposure to secondhand smoke
