Minimum age (years): 18
Maximum age (years): 50

Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Injection into the sphenopalatine ganglion of the patients in both groups will be made by entering the arcus zygomaticum and oriented at a 45 degree angle towards the opposite tooth. Injections will be made with a dental injector. The first group will be injected with 4ml of 1% lidocaine, and the second group will be injected with 4ml of 0.9% saline. Injections will be repeated weekly for the first 4 weeks, then monthly. At the end of the 1st and 3rd months of the treatment, the patients will be evaluated in the routine outpatient clinic control, and the two groups will be compared statistically by questioning the frequency of pain, the number of attacks, the severity of pain (VAS), and the duration of pain.
Primary purpose: TREATMENT

Brief summary: Migraine is a fairly common disease that is a leading cause of disability worldwide. 15% of the general population suffer from migraine headaches. Although there are currently many options for the treatment of acute migraine, these treatment options, such as acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDS), triptans, combinations analgesics and antiemetics, have insufficient efficacy and significant side effects. Therefore, there is a need for new treatment modalities in migraine. Sphenopalatine ganglion (SPG) block is gaining interest as an effective treatment for migraine, other headaches and facial pain syndromes.

In our study, we aimed to block the Sphenopalatine ganglion with a local anesthetic drug and compare it with the placebo control group.

Detailed description: Between 1 May and 1 December 2021, 50 patients aged 18-50 years, who were diagnosed with episodic migraine according to ICD III criteria, who applied to the headache outpatient clinic of Afyonkarahisar Health Sciences University Medical Faculty Hospital, are planned to be included in the study. Patients with similar age, gender and disease duration will be randomly divided into 2 groups using the closed envelope method. Demographic information of the patients, chronic disease history, medications used, and duration of disease will be questioned. Before the treatment, the frequency of pain, the number of attacks, the severity of pain (VAS), and the duration of pain will be questioned. VAS (visual analog scale) is a scale that evaluates the severity of pain. This scale consists of numerical values between 0 and 10. 0 is considered no pain, and 10 is considered the most severe pain. Routine attack treatment of the patients will continue. Injection into the sphenopalatine ganglion of the patients in both groups will be made by entering the arcus zygomaticum and oriented at a 45 degree angle towards the opposite tooth. Injections will be made with a dental injector. The first group will be injected with 4ml of 1% lidocaine, and the second group will be injected with 4ml of 0.9% saline. Injections will be repeated weekly for the first 4 weeks, then monthly. At the end of the 1st and 3rd months of the treatment, the patients will be evaluated in the routine outpatient clinic control, and the two groups will be compared statistically by questioning the frequency of pain, the number of attacks, the severity of pain (VAS), and the duration of pain.
