A rare case of migrainous left bell抯 palsy after migrainous right external ophthalmoplegia - A case report

ABSTRACT

Migraine increased the risk of Bell palsy in the total population. Among migraine patients, between ?30 and <60 years old are at an increased risk of Bell palsy. A migraine is a primary headache characterized by recurrent headache attacks triggered by various factors. As much as 10% of the global population is thought to experience migraine headaches. It was earlier considered that migraine headaches were triggered by the dilation of cerebral vessels, and the recent evidence supports that migraine attacks can also occur in the absence of vasodilation. According to the researchers, the direct neural effects from the trigeminal nerve to the facial nerve could contribute to the risk of facial palsy among patients with migraine. An alteration of the trigeminovascular function has been suggested to trigger migraines. The neurogenic inflammation of the facial nerve trunk caused by its proximity to the dilated posterior auricular/ stylomastoid/ occipital and superficial temporal arteries during a migraine attack leads to a temporary lower motor neuron type of paresis of the muscles supplied by the facial nerve. We herewith report a rare case of migrainous left Bell抯 palsy after migrainous right external ophthalmoplegia, treated with Sumatriptan.
