title: [Post-irradiation neuromyotonia of the masseter muscle].
abstract: BACKGROUND
  Neuromyotonia is a late and rare complication of radiation therapy, consisting of involuntary sustained muscle contractions with a delay in relaxation.
  
  
  METHODS
  We report the case of a 68-year-old man who developed neuromyotonia of the masseter muscle 6 years after irradiation for tonsil carcinoma.
  
  
  CONCLUSIONS
  This observation underlines the importance of a correct diagnosis that can lead to an efficient treatment by carbamazepine.
