Objective: Migraine headaches are one of the most common and debilitating diseases. Chronic migraine (CM) is a type of migraine that reduces quality of life and causes disability. Botulinum toxin A (BT-A) was approved in 2010 by the Food and Drug Administration for CM as one of the treatment options. In BT-A treatment, follow the pain (FTP), fixed-site fixed-dose (FSFD) methods, and combined injections are prevalent. This clinical trial aimed to compare the effects of two methods of BT-A injections in patients with CM to determine the method with the fewest complications, the strongest therapeutic effects, and the lowest costs in improving quality of life. Materials and Methods: In this preliminary clinical trial, 40 patients with CM were screened, and after examining the inclusion criteria, 18 patients completed the trial. After a baseline examination and experiencing a 28-day baseline period, they were randomly divided into FSFD and FTP groups. In our study, we used the Quality of Life Questionnaire, the Migraine Daily Note, and Headache Impact Test-6. Results: A total of 17 women and 1 man completed the trial. Severity and rate of headaches and quality of life scores had better changes in the following months with similar trends in both groups without a significant difference. Conclusion: The comparison of the scores showed an improvement in most patients, but there was no significant difference between the FSFD and FTP groups. However, the results indicated a greater response to the treatment and a higher rate of drug use in the FSFD group.
