How Does Head Trauma Cause Hearing Loss

The Head trauma hearing loss included in a traumatic brain injury (TBI) most usually affects the mechanical process. In the USA alone, surveys suggest that there are over one million cases of traumatic brain injury each year which require hospitalization, and as many as 3 million cases of any head injury, including mild injuries. TBI is usually classified at the time of injury based upon severity, and is categorized as mild, moderate, or severe.

Hearing loss problems can be very isolating and frustrating. if you are traveling with this problem than you must consult with your audiologist.Treatment may include medical management, hearing aids, or auditory processing therapy.

Symptoms of TBI-related ear damage

  • Difficulty understanding speech, especially when there is background noise
  • Difficulty locating sounds (knowing where they are coming from)
  • Tinnitus (a ringing in the ears with no external source)
  • Hyperacusis (extreme sensitivity to sounds)
  • Conductive or sensorineural hearing loss

 

TBI and the Ear

There have been many attempts to develop a system of classification defining all types of head injury, but such analysis attempts have possessed some limitations and lack of agreement because of the variety of ways in which the brain can be injured. Typically, most classification schemes attempt to establish the definition around some alteration in the level of consciousness.

  • Traumatic brain injury can cause a range of problems related to the ear, including hearing loss, vestibular effects, and central auditory problems.
  • Because of the sudden and violent nature of the injury, TBI may cause concurrent damage to the auditory pathway. Damage can occur at any point within auditory pathway, from the outer ear to the cortex, which can result in a variety of complex symptoms.
  • Impairment due to trauma can produce conductive and sensorineural hearing loss, central auditory processing deficits, vestibular impairments, and tinnitus
  • The tympanic membrane, middle ear, and cochlea are the most common sites of peripheral injury as they are often directly in the line of trauma.

 

Hearing loss with mild injuries:

According to the report, dangerous head injuries may suffer permanent, lifelong effects, and those whose injuries are milder may experience negative side effects that last days, weeks, or longer.
