Tinnitus is the perception of an insistent, unpleasant ringing, buzzing or other consistent noise, located in or near the skull but without a definable external source. Tinnitus is often perceived as a ringing or persistent high tone very close to or within the ear. Tinnitus is often regarded as a symptom of auditory conditions, such as damage to the tissues in the ear that control the perception of tones and frequencies. An increasing number of researchers argue that tinnitus is a disorder of the connections between the inner ear and certain areas of the brain. Some scientists had developed a theory that tinnitus was associated with deficiencies in vitamin B12. Chronic inflammation of the middle ear (otitis media) may also be associated with some cases of tinnitus.
Tinnitus related to otitis media may be improved by surgery to correct damage caused by this inflammation. When a fistula forms, blood from an artery under high pressure and flow goes directly into a vein, which is a low pressure and low flow structure.  Even though the fistula is not directly on or within the brain, it can nevertheless lead to brain dysfunction by congesting the brain venous system, as will be explained below. Finally, many patients who have dural fistulas of all sizes and locations can have a myriad of symptoms such as different kinds of headache, tiredness, loss of concentration, memory problems, even hallucinations, psychosis or other psychiatric problems.  Unfortunately, in these patients the diagnosis of dural fistula can be significantly delayed because dural fistulas are relatively rare, while the above symptoms are very common and usually not due to a fistula. For an in-depth presentation on treatment of Brain Dural AV Fistulas, primarily geared towards neurointerventional professionals, you can visit Techniques: Brain Dural AV Fistula Embolization page. Below are pictorial diagrams of what a fistula is like and how it can be treated.  The actual anatomy is much more complicated, but the pictures provide a frame of reference.
Finally, post-embolization views, showing the coils in the cavernous sinus (white arrows) and no evidence of fistula on injections of the external carotid artery (brown arrows).  This approach, though technically challenging, can be quite successful when other venues prove unfeasible.
This patient developed a fistula on the dural covering that separates the back part of the brain, called cerebellum, from the overlying occipital lobe.

The microcatheter has been positioned into another branch of the middle meningeal artery, showing residual fistula and aneurysm.  More glue is injected from this position.

It is not considered to be a condition in its own right, but a syndrome or symptom related to many forms of auditory damage or disorder. Age-related hearing impairments, or disorders of the circulatory system around the ear, may also be related to this complaint.
Some scientists conclude that tinnitus is in fact related to damage of the nervous tissue in or around the auditory cortex of the brain.
A recent study including 100 patients with tinnitus found that 63 of these had low vitamin B12 levels.
As the natural molecule histamine is associated with the regulation of both inflammation and some auditory nervous tissue, drugs that block its receptors in the brain are currently proposed as treatments for tinnitus. Darius Kohan is renowned for his otology expertise and has been highlighted on several outlets such as a CBS spotlight on tinnitus and is often cited in WEB MD and other medical outlets. Our group at the NYU Langone Medical Center is one of the premier neurointerventional centers in the world. When a fistula forms between an artery and a vein within the dura, it is called Brain Dural Fistula, or Brain Dural Arteriovenous Fistula, or BDAVF, etc.
The total amount of radiation delivered to the patient at conclusion of a dynamic CT scan, however, can be VERY high — in some cases resulting in (usually temporary) hair loss. The bottom picture is venogram obtained by directly injecting the cavernous sinus to demonstrate the basal vein (dark blue) and ophthalmic vein (light blue arrows).  Some coils have already been placed into the sinus.


Other cases may be related to exposure to very loud or destructive levels of noise, such as from an explosion, industrial equipment or farming equipment.
Others have found associations between increased activity in further brain regions, age of tinnitus onset and distress caused by the syndrome. However, treating this deficiency had no significant effects on the complaint in these patients. Other new and emerging treatments for tinnitus focus on the potential indicated by the studies into its links with abnormal brain activity, as mentioned earlier. The details of any treatment are best discussed with the specialist performing the procedure. Tinnitus may have a significant negative impact on the life quality of those affected by it.
Different research groups have concluded that chronic tinnitus may be associated with an impaired connection between the cerebral cortex, which controls advanced functions such as memory, perception of the environment and cognition, and the thalamus, which supplies the cortex with sensory information. A recent study, including 974 patients, indicated that hearing aids were preferable and more effective in treating blast-related tinnitus compared to noise generators. Presuming further research confirms the findings of these studies, deep brain stimulation (a form of implant placed in the brain to correct this activity) may be a viable option for severe treatment-resistant tinnitus. This syndrome may also have deleterious effects on the emotional, psychological and functional status of the patient.
