How Botox can knock a migraine on the head

Research shows wrinkle drug can reveal muscles in the face and neck
that trigger headaches
MIGRAINE can be treated successfully by using Botox to identify the
muscles triggering the headaches and then removing them surgically,
an American study indicates.
A very common and disabling condition, migraine is suffered by as
many as six million people in Britain, 10 per cent of the population.
It is by far the most common neurological condition, more common than
diabetes, epilepsy and asthma combined.
Most people treat their migraine attacks with painkillers but the
group of patients taking part in a small British trial had a much more
radical treatment.
For several years Bahman Guyuron, a plastic surgeon
at Case Western Reserve University in Cleveland, Ohio, has argued
that migraines are
triggered by muscles in the face and neck. He came up with the idea
after finding that patients who had had a “forehead lift” to
remove furrows subsequently suffered less from migraine.
The idea is controversial because most experts believe
that migraines are neurological, caused by changes in the brain and
not by muscle
tension. So Dr Guyuron set out to do a proper trial. He used Botox
injections, which paralyse the muscles, to identify which were responsible
in each patient and found four distinct areas — the forehead,
temple, back of neck and around the nose.
The 89 patients then underwent surgery to remove the muscles. In Plastic
and Reconstructive Surgery, he reports that the frequency, intensity
and duration of the migraine attacks were reduced for 92 per cent of
the patients studied and eliminated for 35 per cent.
Patients were able to lead much more normal lives
after surgery. Beforehand they missed on average 4.4 days of work
each month. Afterwards they
missed just 1.2 days. The treatment also reduced the annual cost of
migraine care for the patients from around £3,900 to £480.
Dr Guyuron said: “The economic impact of migraine
headaches on businesses is staggering due to the loss of employee
time and
productivity. By identifying the trigger areas for migraines and performing
targeted
surgical procedures, we significantly reduced or eliminated their
migraines and the amount of time missed from work.
“Before surgery my patients expressed extreme
frustration at not being able to gain control of their lives. They
wanted to work
or spend time with their family. Through our new surgical discoveries
we are able to help patients escape the awful effects of migraines
and start living their lives again.”
Dr Guyuron’s work has proved controversial in
the US where some neurologists have claimed that muscles are simply
not involved in
migraines. But he says that the results speak for themselves.
Alan Bartle, chief executive of the Migraine Trust,
said new approaches were welcomed. “This study would seem to indicate that for a
defined subgroup of patients with migraine this may be an approach
worth considering following proper diagnosis and after other treatment
options have been tried,” he said.
But Mr Bartle said other studies into the use of Botox injections
alone had so far proved inconclusive.
“This latest study is a further procedure, which is invasive
and does show some sideeffects. I would wish to see further studies
with fully randomised, double-blinded, placebo-controlled trials among
significant numbers with long-term follow up before being able to comment,” he
added.
