LEAL FILHO, Manoel Baldoino et al. Hemifacial spasm in basilar impression and Arnold-Chiari malformation: Case report. Arq. Neuro-Psiquiatr. [online]. 1992, vol.50, n.3, pp. 387-390. ISSN 0004-282X. http://dx.doi.org/10.1590/S0004-282X1992000300022.
The authors report a case of symptomatic basilar impression and Arnold-Chiari malformation being presented as the first symptom of hemifacial spasm. The surgical treatment of the malformation resulted in inprovement of the clinical manifestation with reduction of the hemifacial spasm. The need for the aetiological therapy for the hemifacial spasm is emphasized, before symptomatic treatment with botulinum toxin is tried.
