How Traumatic Brain Injury Affects Hearing

Hearing problems are quite common after a traumatic brain injury (Tbi) because the inner ear is directly associated to the central nervous system. Ringing in the ear (tinnitus) and hearing loss are two of the most widely reported side effects of a traumatic brain injury. Some other hearing problems that may occur following a brain injury comprise hyperacusis (normal situations seem very loud); mystery filtering one set of sounds from background noise; and auditory agnosia (also called pure word deafness). Auditory agnosia is a health in which the man is unable to recognize the meanings of inevitable sounds.

Following a Tbi, hearing problems can occur for a estimate of reasons, both mechanical and neurological, particularly when the inner ear and/or temporal lobes have been damaged. External bleeding in the ear canal, middle ear damage, cochlear injury and/or temporal lobe lesions can all cause auditory dysfunction.

Children who suffer Tbi typically face further problems in the areas of communication, acquiring new information, spatial orientation, task completion, impulse control, and collective conversation.

How Traumatic Brain Injury Affects Hearing

The inner ear is made up of a series of delicate membranes, which can literally rupture during a head trauma. The cochlea, which is the prominent spiral-shaped bone in the ear, can be damaged by a strong blow to the head causing hearing damage. Other types of membrane damage may cause hearing loss as well as dizziness (vertigo) and nausea. Sometimes, surgical operation can accurate damage to the inner ear.

Because hearing loss limits or takes away one of the traditional means we use to communicate, hearing loss has the potential to complicate many of the other side effects of brain damage, generally cognitive and collective problems. Many Tbi victims already suffer cognitive issues such as problem finding words, and these problems are only exacerbated if the sick person cannot hear what is going on around him.

Fortunately, for some Tbi victims, hearing problems disappear a few weeks after the crisis that led to the patient’s brain damage, but other hearing problems will last indefinitely. Since many hearing problems cannot even be detected by the sick person himself after the Tbi, it is recommended that anything suffering a traumatic brain injury be evaluated by an audiologist, even if nothing appears to be wrong with the victim’s hearing.
