[Post-irradiation neuromyotonia of the masseter muscle].
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.
