[Sudden deafness and vestibular failure in the cervical syndrome (author's transl)].

Acute onset deafness with vestibular failure in the cervical syndrome could be due to embolism of the labyrinthine artery. Probably the symptomatology of the cervical syndrome developes independantly. Two patients with sudden deafness and vestibular failure are reported. Embolism of the labyrinthine artery in at least one of these patients appears to have occurred. The prognosis in respect of recovery of function is unfavourable.
