"Follow the Sutures". A New Procedure for Injection of Botulinum Toxin for Chronic Migraine

There is no doubt that chronic migraine is a large public health problem, which is both disabling and costly. Many patients and headache doctors see Botulinum toxin (Botox) treatment as a big stride forward, but it is a problem that the effect has been shown in only one study, with a low therapeutic gain. For this reason, before this costly treatment is expanded to potentially several thousand patients in Norway, it would be highly desirable that 1) there is additional good scientific evidence for use of Botox , 2) a more effective treatment procedure is developed, 3) the potential for unblinding is reduced, and 4) the dose, number of injection sites and cost can be halved, and 5) the adverse effects are minimized. These may be the results of this pilot project where injections are given along the sutures, which can open up for a later randomized, blinded and controlled study.
