title: Dystonic frowning without blepharospasm.
abstract: We report on two cases who presented with involuntary facial grimacing and frowning. Blepharospasm has never been documented in one, and the other case showed difficulty in lid opening only in the early phase of the disease. Botulinum toxin was effective for both. This is a hitherto unreported presentation of upper facial dystonia without interference of eyelid motor control.
