[Vertigo of traumatic origin].

Patient referrals very frequently occur for ill-defined vertigo that appeared some months or even years after a trauma. These should not, however, be considered as cases of functional vertigo. The vertigo is very real, may last several years and constitute a genuine disorder. Such cases are amply described in the literature. Although we cannot perfectly explain the physiopathology, we should not conclude that these patients are not ill. In 50% of cases, we can evidence the signs with radiology and electro-nystagmography provided a properly established protocol is followed. The success of the treatment proposed can be evidenced by cervical electronystagmography.
