AbstractSphenopalatine blocks have been used to treat pain for more than 80 years. Anecdotal support for sphenopalatine ganglion blocks has been very strong in those who believe in the technique, but the research results have been inconclusive. Therefore, a double blind, placebo-controlled study was performed on 61 patients, 42 with fibromyalgia and 19 with myofascial pain syndrome. Pain was measured using visual analogue scales prior to treatment, during treatment, and 28 days after the treatment. Headaches were evaluated in frequency and location prior to and after treatment. Sphenopalatine ganglion blocks were performed under direct vision using 4% lidocaine and sterile water as a placebo. Analysis of the results showed no statistical differences between the lidocaine and the placebo groups.
