Summary

Benign paroxysmal positional vertigo (BPPV) and its subtypes are caused by dislocation of otoliths or clotted otolith fragments, which can be deposed within the three semicircular canals. Primary and secondary forms are differentiated. Non-responders of treatment by means of different positional head manoevers have to be examined in detail to exclude central nervous diseases or the involvement of more semicircular canals ipsi- and contralaterally. The observation of the nystagmus direction and the angular point of torsional nystagmus in Dix-Hallpike or is crucial. According to the results of diagnostic positional tests and barbecue rotation manoevers different subtypes of BPPV have to be differentiated and must be treated by different treatment strategies. In rare cases only posterior semicircular canal occlusion is indicated.
