7 Things That Can Go Wrong With Vestibular Information From One Ear

What Happens When the Brain Gets Abnormal Information Coming From One Ear?

It can be confusing for the brain when one inner ear is telling a different story that the other inner ear is telling

When the brain receives information about movement or position from one ear that doesn't match the other ear, error signals alert you that something is wrong. Many different things can affect the vestibular information from one side, such as:

1. Ear infections
2. Vascular changes
3. Tumors
4. Perilymphatic Fistula (a small hole that can occur in the labyrinth)
5. A concussion or other trauma affecting only one labyrinth
6. Mechanical problems like BPPV. Benign Paroxysmal Positional Vertigo, which is common especially among older adults, is the most common cause of a false sensation of spinning (vertigo).
7. Alterations in fluid pressure in one labyrinth like Endolymphatic Hydrops/Meniere's disease

What Happens When Fluid Pressure Shifts in the Inner Ear?

With conditions such as Meniere's disease or Endolymphatic Hydrops, fluid pressure can shift periodically in the inner ear. When the fluid balance is disturbed, the pressure in one ear can suddenly go awry. In this case you have a large mismatch of information coming to the brain that can be quite incapacitating.

Does Vestibular Rehab Help Ringing in the Ears?

What Causes Ringing in the Ears?

Ringing in the ears is referred to as "tinnitus" and is usually assessed by an ENT doctor and an audiologist

Ringing or buzzing in the ears is referred to as “tinnitus” and is usually assessed by an Ear, Nose, Throat doctor and an Audiologist.  Tinnitus is typically a symptom of a related problem with hearing nerves, different parts of the ear, or the part of the brain that interprets information.  According to the Tinnitus Association of Canada, “150,000 Canadians experience a degree of tinnitus that significantly affects their quality of life”.

The Canadian Academy of Audiology reports that the exact mechanism underlying tinnitus is not known, but that some of the causes can include:

• Outer ear disorders such as excessive ear wax, a hair touching the eardrum or a perforated eardrum
• Middle ear disorders such as an ear infection
• Inner ear disorders like damage due to noise exposure, hearing loss related to aging, or Meniere's Disease

How Does Vestibular Rehabilitation Differ from Tinnitus Treatment?

It is important to understand that Vestibular Rehabilitation DOES NOT address tinnitus.  If you have dizziness, unsteadiness and sensitivity to motion in addition to your hearing-related issues, then Vestibular Rehabilitation can be helpful with those symptoms, but you should not expect your tinnitus to change.  

Having said that, research is finding that some peoples’ tinnitus has an element of mechanical contribution to it that can come from the jaw-joint (TMJ) or neck.  If you seem to be able to alter your tinnitus with certain head, neck or jaw movements, posture, or trigger points, then it’s possible that therapy focused on these areas may help reduce tinnitus.  This is referred to as ‘somatically related tinnitus’ and research is showing positive outcomes with treatments such as TENS, therapeutic exercise, manual therapy, biofeedback/stress reduction and education.
