Medical research believes that the cause of tinnitus can be found in the inner ear. Medical research believes that the overstrained hearing cells doe not have the energy needed for polarisation. The cells remain in a permanent agitation which is felt as a permanent noise. The later felt perception of permanent tinnitus should recede by means of signal processing within the hearing parts of our brain. The fixation of the disturbance signal in the hear paths of our brain make it permanently audible.

Other hypothesis assume a circulatory disorder of the inner ear and try to control it by infusions. Chances of success are unfortunately minimal and are in the range of placebo cure.

We could prove that both pathophysiological theories are not correct. They are a little geared: the first theory as it cannot describe the scope of power of tinnitus. The second hypothesis does not seem reliable if you take the vast number of younger patients mostly being under permanent stress. Circulatory disorder at an age of approximately 30 years are quite unlikely.

Tinnitus more likely is caused by a feedback phenomena in the reaction coupling of the eardrum. Cause is an infection of the complete hearing system , damaging respective filter functions, averting normal feedback.

We could identify micro-organisms responsible and achieve with specific therapies a cure of significantly more than 80 % when tinnitus is lasting for less  than 6 months.

But it is as in normal life. The longer the situation exists, the harder it is to change. This means that patients with chronic tinnitus can only be cured by a prolonged therapy concept on the basis of  the CITERA™ technology.
