The Importance of Early Detection of Hearing Loss

The ability to hear is very important for children to develop language and speech skills as they grow. In the past, loss of hearing was not detected until the child was around two years old. Research and studies have shown that detection of loss of hearing before a child is six months old generally results in better outcomes than when done after six months of age. Because of this, screening of newborn hearing has become popular in hospitals across Canada, and children with hearing loss are being identified at much younger ages and treated.

Treatments for Childhood Hearing Loss

Hearing aids, cochlear implants and a combination of assistive listening or speech therapy devices are recommended forms of treatments. If your child shows any of the above signs, take him or her to a pediatric audiologist to have his or her hearing tested. Also, the child may have wax buildup, an ear infection or any other problem causing the loss of hearing, the audiologist or otolaryngologist (Ear, Nose and Throat also known as ENT Physician) will have the obstruction removed.

Thanks to technological advancement in the medical space, children with hearing loss now have the hope of regaining their hearing ability.
