A 40-year-old male presented with hemifacial spasm manifesting as paroxysmal spontaneous twitches in the left peribuccal region persisting for 3 months. The symptoms began 7 days after an accident, when a signboard hit his left mandibular angle. Physical examination showed no trauma-related change in his face, and no neurological abnormality except for the twitches. Magnetic resonance imaging also showed no abnormalities of the facial nerve and adjacent regions. Electrophysiological studies showed synkinesis, so hemifacial spasm caused by peripheral facial nerve injury was suspected. The symptoms subsided 4 months after the injury. Blunt injury to the facial nerve branches might cause hemifacial spasm.

“…Myoclonic jerking of the paraspinal muscles due to malignant tumours involving thoracic roots and focal myoclonus after lumbar laminectomy or lumbosacral radiculopathy, electric injury to the brachial plexus and other kind of peripheral nerve system damages are rare but well-known entities 1,3,4 . A more common condition, hemifacial spasms can also be triggered by a VII nerve injury, usually by a mass lesion in the cerebellopontine angle but even in other sites related to the extra-cranial branches in the face [1][2][3] .…”

Multiple pathophysiological mechanisms are probably involved, including abnormal branching after aberrant axonal regeneration and enhaced facial motoneural excitability 2 .…”

“…Brito e Silva 16 , em estudo de 164 casos dessas malformações, encontraram três casos de EH e propuseram a distensão do tronco encefálico e do nervo facial, com consequente diminuição do fluxo sanguíneo para essas estruturas, como mecanismo fisiopatológico adicional à compressão do próprio nervo facial. Outras causas de EH são: paralisia de Bell, doença de Paget, esclerose múltipla, meningoencefalite, aracnoidite 6,12,16,18,19 , infarto lacunar pontino 17 , aneurisma da fossa posterior 20 e lesões traumáticas dos ramos distais extracranianos do nervo facial 21 .…”

RESUMO -Os autores relatam os achados clínicos e angiográficos de dois casos de espasmo hemifacial familiar. Esta é a quinta descrição sobre esse tema na literatura e apresenta mãe e filha com idades de 76 e 51 anos respectivamente, nas quais o lado esquerdo foi o acometido. Exames de angiorressonância realizados nas pacientes revelaram dolicobasilar com origem lateralizada à esquerda para ambos os casos. Também demonstraram artéria cerebelar póstero-inferior muito desenvolvida e irregularidades murais nas artérias vertebrais e basilar sugestivas de arteriosclerose na mãe e vasos intracranianos levemente alongados na filha. Dados de revisão da literatura e sobre a etiologia do espasmo hemifacial são enfocados.PALAVRAS-CHAVE: espasmo hemifacial familiar, angiorressonância, nervo facial, compressão nervosa. Familial hemifacial spasm: report of two casesABSTRACT-The authors report the clinical and angiographical findings of two cases of familial hemifacial spasm. This is the fifth description in the literature and presents mother and daughter at the ages of 76 and 51 respectively, in whom the left side was affected. They underwent exams of angioresonance that showed dolichobasilar with left side origin in both patients. The exams also demonstrated postero-inferior cerebellar artery very developed and irregularities in the walls of the vertebral and basilar arteries suggestive of arteriosclerosis in the mother and slightly elongated intracranial vessels in the daughter. Literature review and etiology data of the hemifacial spasm are focused.KEY WORDS: familial hemifacial spasm, angioresonance, facial nerve, nerve compression.O espasmo hemifacial (EH) é um distúrbio do movimento caracterizado por contrações involuntárias paroxísticas dos músculos inervados pelo nervo facial. Em sua forma típica de apresentação surgem contrações involuntárias intermitentes da metade inferior do músculo orbicular dos olhos, em um dos lados da face, que gradualmente pioram em frequência e intensidade e, posteriormente, passam a acometer a porção superior do referido músculo. Após meses ou anos, os espasmos podem estender-se para outros músculos homolaterais inervados pelo facial. Os músculos platisma e frontal são acometidos somente em 15% dos casos 1,2 . Quando o músculo estapédio é acometido, os pacientes referem tinidos no ouvido homolateral ao EH, sincrônicos com as contrações musculares 3,2,4 . Nos casos mais graves, discreta paresia hemifacial ipsilateral pode ser observada [4][5][6][7][8] . O EH é unilateral na maioria dos casos e raramente são encontrados casos de EH bilateral 9,10 , os quais são sempre assimétricos e assincrônicos. Em relação à idade de instalação, o EH predomina na
