RESULTS
One hundred twenty chronic migraine patients who had undergone GON block
were included in the study. The mean age of these patients was
42.68±7.14 years. Of the patients, 102/120 (85%) were female, and
18/120 (15%) were male. The patients’ mean pain duration was 11.63±5.66
hours. 17/120 (14.2%) patients described pre-headache aura. The
demographic and clinical characteristics of the patients were presented
in Table 1. (Table2)
The number of days with pain, the number of analgesics used per month,
the VAS and MIDAS scores before and one and three months after the
treatment were recorded. With the GON block, the number of days with
pain regressed from its pre-treatment value of 8.5 [8-12] to 4
[3-4] at the 1st month and 3 [2-4] at the
3rd month. The number of analgesics used monthly by
the patients was 14 [10-16] before treatment, 5.5 [4-6.5] at the
1st month, and 6 [5-7] at the
3rd month. The VAS score regressed from its
pre-treatment value of 8 [7-9] to 4 [3-4] at the
1st and 3rd months. The MIDAS score
also regressed from its pre-treatment value of 4 [3-4] to 2
[1.5-2] at the 1st and 3rdmonths. Significant reductions were observed regarding the number of
days with pain, analgesic use, and the VAS and MIDAS scores when the
1st-month and 3rd-month values were
compared to the pre-treatment baseline values (p<0.001*).
There were no statistically significant differences between the
1st-month and 3rd-month values
(Table 2) (Figures 1, 2, and 3).
