Abstract

Efficacy of Trans Nasal Sphenopalatine Ganglion Block In Migraine

he Sphenopalatine ganglion (SPG), a parasympathetic ganglion in the pterygopalatine fossa, is involved in the activation of trigemino autonomic reflex, a pathway responsible for the symptoms of migraine and other primary headaches. Hypersensitivity of the SPG may be responsible for the escalating pain and repeated attacks in migraine. Blocking the Sphenopalatine ganglion may result in aborting of an acute migraine attack as well as decrease the frequency of subsequent attacks by decreasing hypersensitivity of the SPG.
