[Botulin in the treatment of local dystonia].

Botulin A has been introduced for the treatment of local dystonia especially blepharospasm and torticollis. Three cases of blepharospasm and 5 cases of torticollis were treated with botulin injections directly into the muscles by a method presented in detail. Good effects were obtained in blepharospasm but very poor in torticollis, which may have been due to too low doses of the toxin and inadequate choice of injection points. The method is safe and in only 1 case transient weakness of the masseters was noted.
