title: Injecction of trigger points in the temporal muscles of patients with miofascial syndrome.
abstract: OBJECTIVE
  The aim was to examine the effect of blocking trigger points in the temporal muscles of patients with masticatory myofascial pain syndrome, fibromyalgia and headache.
  
  
  METHODS
  Seventy patients with one trigger point were randomly divided into 3 groups: injection with saline or anesthetic and non-injected (control).
  
  
  RESULTS
  Pain was reduced in 87.71% patients injected with saline and 100% injected with anesthetic. Similar results were obtained for headache frequency. With regard to headache intensity, the injection groups differed from the control group, but not between themselves.
  
  
  CONCLUSIONS
  Treatment with injection at trigger points decreased facial pain and frequency and intensity of headache. Considering the injected substance there was no difference.
