What Is Post-Traumatic Tinnitus?

Tinnitus — often described as ringing, buzzing, clicking, or hissing in the ears — affects a significant number of individuals following a concussion or mild traumatic brain injury. While it’s commonly associated with direct ear trauma or loud noise exposure, many patients report tinnitus after head injuries without any obvious damage to the ear itself.

This can make the symptom incredibly frustrating and difficult to understand — especially when it becomes chronic.

Why Does Tinnitus Occur After a Concussion?

The exact mechanisms remain complex, but several theories have strong support:

1. Vestibular and Auditory System Disruption

The inner ear (which houses both the cochlea and vestibular system) may be affected by concussion, leading to dysregulation of sound and balance processing. Even without direct trauma, sudden shifts in cerebrospinal fluid pressure and inflammation may impair auditory nerve function.

2. Cervicogenic Contribution

Neck injuries often co-occur with concussions and can contribute to tinnitus. This is thought to occur due to somatosensory dysfunction and altered cervical input to brainstem centers involved in auditory processing(1).

3. Autonomic Nervous System Dysregulation

Heightened sympathetic activity (fight-or-flight) following concussion may exacerbate tinnitus. Increased nervous system arousal is often seen in patients with persistent symptoms, including ringing in the ears(2).

4. Emotional and Cognitive Factors

Anxiety, stress, and hypervigilance — all common post-injury — can heighten awareness of tinnitus and increase its perceived intensity. Sleep disruption and fatigue can worsen this cycle.

5. Inflammation and Neurochemical Imbalance

Neuroinflammatory changes following concussion may affect auditory pathways. Research suggests altered neurotransmitter levels (e.g., glutamate, GABA) may contribute to the perception of phantom sounds(3).

How to Treat Post-Traumatic Tinnitus

1. Address Neck Dysfunction

If tinnitus is worsened by head or neck movement, or accompanied by neck pain or dizziness, a cervical spine evaluation is essential. Treatment may include:

  • Manual therapy
  • Cervical proprioceptive training
  • Postural correction
  • Vestibular rehabilitation

2. Manage Stress and Hyperarousal

Breathing exercises, mindfulness, and nervous system regulation strategies (such as vagus nerve stimulation and graded exercise) can help down-regulate sympathetic tone and improve tolerance to tinnitus.

3. Treat Underlying Vestibular Dysfunction

Patients with tinnitus and dizziness or motion sensitivity should undergo vestibular testing. Vestibular therapy can help regulate sensory processing and reduce tinnitus severity in select patients.

4. Hearing Assessment

Although tinnitus may be neurological in origin, patients should be screened for hearing loss or auditory damage. Audiological testing ensures no peripheral deficit is missed.

5. Sleep and Environmental Modifications

Background noise (white noise machines), reducing screen exposure before bed, and sleep hygiene practices can all reduce tinnitus severity at night.

When to Seek Help

Tinnitus should not be ignored — especially if:

  • It worsens over time
  • It’s accompanied by balance issues or dizziness
  • It disrupts sleep or daily functioning
  • It’s linked to anxiety or emotional distress
