Repetitive multiple cranial nerve blocks can be
used as a preventive treatment for chronic migraine. Moreover, it shows minor
post block complications.
As per a recent
single-centre prospective cohort study, the repetitive multiple cranial nerve
blocks (MCNBs) can effectively prevent chronic migraine. Greater occipital
nerve (GON) blocks have been used for the acute and transitional treatment of
migraine but its efficacy for prevention of migraine was not studied before.
In this study,
the demographic and outcome data on chronic migraine patients who had MCNBs in
the headache service between June 2017 and March 2019 was collected.
The measured
outcomes were Headache Impact Test 6 (HIT6), reduction in headache days and
patient-reported effectiveness MCNBs. At 4 weeks, out of 64 patients, 42
responded well to the MCNBs, their headache days reduced by at least 30% post
block. Out of 112 (8%) instances of minor post block 9 complications were
documented with a total of 501 injections.
With remarkable
efficacy, the MCNBs could be used as an alternative preventive treatment for
chronic migraine.
