title: Efficacy of regional nerve block in management of myofascial pain of masseteric origin.
abstract: OBJECTIVE
  To compare the efficacy of a regional masseteric nerve block (MNB) in the management of myofascial pain of masseteric origin, relative to trigger point injection (TrP-Inj) and intra-oral stabilization appliance (IOA).
  
  
  METHODS
  A retrospective chart review of 200 patients treated for myofascial pain of masseteric origin was performed. Sixty patients met the eligibility criteria and were grouped based on their treatment regimen; IOA, TrP-Inj or MNB. Pain scores recorded at pre-treatment (baseline), 30 minutes post-treatment, and 2 weeks post-treatment were analyzed.
  
  
  RESULTS
  Treatment with MNB resulted in significant reduction in pain at 30 minutes and two weeks post-treatment compared to TrP-Inj and IOA.
  
  
  CONCLUSIONS
  MNB provided an immediate and sustained therapeutic effect for the management of myofascial pain for at least up to two weeks. MNB is a simple and valuable tool in the management of myogenous pain, especially for the non-orofacial pain practitioner.
