Intramuscular injection of botulinum toxin type A is the treatment of choice for most cases of oromandibular dystonia. We report on five patients with oromandibular dystonia that developed secondary nonresponsiveness to botulinum toxin type A following multiple injections over a 6‐year period. © 2002 Movement Disorder Society.
