Abstract
Spasmodic dysphonia (focal laryngeal dystonia) is a chronic neurologic disorder affecting normal speech production. There are two types of presentation: the adductor type producing ‘strain-strangled’ speech; and the abductor type producing breathy breaks or a ‘whispering speech pattern.’ Botulinum toxin injections are currently the best treatment for managing the disabling symptoms.
