TEIVE, Hélio A.G. et al. Jaw-opening oromandibular dystonia secondary to Wilson's Disease treated with botulinum toxin type A. Arq. Neuro-Psiquiatr. [online]. 2012, vol.70, n.6, pp.407-409. ISSN 0004-282X. http://dx.doi.org/10.1590/S0004-282X2012000600005.
We have reported a case series of five patients with jaw-opening oromandibular dystonia secondary to Wilson's disease (WD), in which the patients were treated with botulinum toxin type A (BTX-A). In all cases, dystonia score was partially reduced three weeks after injections. The most common side effect was transient mild dysphagia. This preliminary study showed that jaw-opening oromandibular dystonia in WD may be partially responsive to the use of BTX-A.
