The Masticatory Myofascial Pain Syndrome (MMPS) is a clinical entity characterized by the presence of trigger points in the masticatory muscles. It is due to local muscle injury caused by overloading an excessive discharge of acetylcholine at the neuromuscular junction. The application of botulinum toxin type A (TBA) in myofascial trigger point works by inhibiting the release of acetylcholine triggering a flaccid paralysis and muscle relaxation. The aim of this study was to determine the therapeutic effect of BTA in the treatment of MMPS using Visual Analog Scale of Pain. (Scale that measures pain from 0 to 10). The type of study was controlled clinical trial, prospective, longitudinal and random. Twenty-eight patients of the Service of Oral and Maxillofacial Surgery at the Hospital Nacional Hipólito Unánue met the inclusion criteria. Fourteen of them was applied to TBA and the other, placebo (saline 0.9%) and monitored for 4 weeks. TBA was found that pain decreased dramatically, from 6.36 to 0.57. In contrast to the control group dropped from 5.36 to 4.36. We conclude that the TBA applied intramuscularly in masticatory trigger points was more effective than placebo for the treatment of MMPS.
