Cervical dystonia after ear surgery.
BACKGROUND
The pathophysiology of primary focal dystonia remains insufficiently understood, but may be explained by a 'double-lesion' model, in which a particular trigger on top of an intrinsic susceptibility due to a certain genetic predisposition can induce dystonia.


METHODS
Here, we describe a patient who developed cervical dystonia soon after ear surgery (revision stapedectomy), which had caused vestibular hypofunction.


CONCLUSIONS
We also discuss other cases of dystonia associated with vestibular lesions and with other reported triggers, and put these into the context of the possible pathophysiology.
