Five patients with long term recurrent vertigenous attacks subsequent to profound sudden hearing loss were observed neurotologically and the related pathology was investigated.Characteristic findings were as follows;1) subjective; positional vertigo2) objective; direction changing positional nystagmus and marked canal paresis in the bithermal caloric test3) no fluctuating tinnitus or hearing loss; the cerebellopontine angle cystic arachnitis and broad vascular disorder including those in the central nervous system were assumed to be the etiology. Concerning the arachnitis, physiomechanical, inflammatory, and/or a hydrodynamic influence on the labyrinth via the perilymphatic system were seemed likely to occur.
