Migrainous facial palsy (MFP): the introduction of a new concept of neurovascular conflict and its preliminary clinical evidence

ConclusionWe concluded that 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.SignificanceThis pathophysiological understanding of the disease mechanism could open new avenues as to the treatment of this condition. This proposition indicates in clearer light than before, a possible mechanism to explain the higher incidence and risk of facial palsy in migraineurs.
