Abstract
A new method of treatment of vascular headaches (migraine, cluster) as well as atypical pain is presented, comprising the application of bursts of low power laser light to the area of intra-oral tenderness associated with the above conditions. This zone of tenderness is in the area of the plexus formed by the posterior and middle superior alveolar branches of the ipsilateral maxillary nerve. The intra-oral tenderness associated with vascular headaches and facial pain disappears almost immediately, returning in approximately three hours to a few days. With repeated applications, a marked decrease/elimination of the intra-oral tenderness and similar elimination of vascular headache and facial pain frequency and intensity has been observed. The treatment comprises the brief application of bursts of low power laser light (non-cutting 2 mW) from a low-power helium-neon laser, having a maximum output of 5 mW, utilizing an application time of 20 to 30 seconds.
