Laryngeal dystonia--personal experience with botulin toxin treatment

Laryngeal dystonia is a focal dystonia occurring more often than it is diagnosed. Adductor type dystonia was described in 5 patients. In 3 cases it manifested itself as blepharospasm, which later developed into Meige's syndrome. The patients were treated with botulinum toxin A injections under EMG control administering 10 i.m. into laryngeal muscles on both sides with good and very good results. There were no serious side effects.
