[Clinical study of benign paroxysmal positional vertigo recurrence].
OBJECTIVE
To investigate the cause of recurrence and clinical significance in benign paroxysmal positional vertigo (BPPV).


METHODS
By retrospectively analyzing the clinical data and results of TCD, CT or MRI of head of 65 patients with non-recurred BPPV and 44 patients with recurred BPPV in 2 years after successful canalith repositioning maneuver.


RESULTS
The prognosis of BPPV shows significant correlated with age, family history, migraine history, intracranial arterial and carotid stenosis and stroke history.


CONCLUSIONS
Many causes play part in the recurrence of BPPV, but most of them correlate with blood disturbance of labyrinth. We can know the causes of recurred BPPV from the clinical data and results of TCD, CT or MRI of head and predict its recurrence, and do corresponding intervention eventually.
