Background: Migraine is a chronic headache manifested with attacks. Here we aimed to evaluate and compare the efficacy of 15-point Dysport injection with 31-point Xeomin injections. Materials and Methods: This is a randomized clinical trial performed in 2020–2021 in Isfahan on patients with refractory chronic migraine. A total number of 60 patients entered the study. The pain of patients was also determined using headache impact test (HIT) questionnaire. Patients were randomized into two groups: Group 1 underwent 31-point Xeomin injection and Group 2 underwent 1 vial of Dysport injection into 15 points of the scalp. Results: Our study revealed that the data regarding aura, nausea, vomit, photosensitivity, sensitivity to sounds and smells did not change significantly between two groups compared to the beginning of the study. Frequency, duration, intensity of headaches, and the mean HIT score of all patients improved significantly within 3 months after interventions. Comparing both groups showed no significant differences (P > 0.05). HIT score was decreased from 21.26 ± 3.58 before intervention to 15.51 ± 4.58 after 3 months in Group 1 and 22.23 ± 2.59–10.33 ± 2.26 in Group 2. In both groups, these changes were statistically significant (P < 0.001). Although we found more decrease of HIT score in Group 2 comparing with Group 1 (10.33 ± 2.26 vs. 15.51 ± 4.58), this difference was not statistically significant (P = 0.12). Conclusion: Although Xeomin and Dysport injections are both effective and reduced pain in patients with chronic migraine, our new technique is probably better than the standard technique. Because the injection points are halved, increase patients comfort and reduce overall cost.
