About this study

This is a double blind placebo-controlled study which will evaluate the efficacy of bupivacaine compared to saline, delivered by the Tx360® device to the sphenopalatine ganglion (SPG), to treat chronic migraine headache. The Tx360® is a nasal applicator which is cleared through the FDA for transnasal medication delivery, including delivery to the SPG. The SPG has been implicated in a variety of cephalalgias. It is critical to the success of this intervention that the blocking agent be accurately delivered to this area as it is the only non-bony access to the pterygopalatine fossa (PPF). Subjects meeting inclusion/exclusion criteria will receive 12 intranasal treatments to the SPG over a period of 4 weeks with follow-up monthly for an additional 3 months post-treatment.
