Tinnitus of cortical cerebral origin

Abstract

Amongst our neurootological patients we frequently find multisensorial syndromes, for instance with combinations between tinnitus, hearing impairment, vertigo and nausea.

The statistical results are exhibiting that tinnitus is bound to a multifactorial disease background. The topodiagnostic analysis of the stato-acoustic data shows that there exists significantly more central than peripheral pathology.

With electro-cochleography, brainstem audiometry and cortical response audiometry it was possible to record potentials from the inner ear, the brainstem and the auditory cortex. This has significantly improved the analysis of auditory symptoms like tinnitus and assisted in the differential diagnosis of hearing disorders.

Since now, cortical projections of the vestibular system are known and as it has been proved since more than 20 years, that there exist the possibility of vestibular evoked potentials, which then leads to detect that the dwelling point of the tinnitus in the area 41 of the temporal lobe of human cortex.

The typical caloric butterfly patterns of «2002» or «0220» are pointing to the same area.  Thus the acoustic and the vestibular approaches towards tinnitus of the cortical type are clinically investigated by cases of the Bad Kissingen databanks NODEC.

The findings are presented with respect to case reports as well as with statistics.
