Trismus (or Lockjaw): Pathophysiology, Etiology & Management

Trismus refers to restriction of the range of motion of the jaws. Commonly known as “lockjaw,” trismus typically originates from a sustained, tetanic spasm involving the muscles of mastication. Earlier it was primarily related to tetanus but currently it refers to restricted mouth opening due to any etiology. Mostly trismus is a bilateral process that stems from increased tone mediated by the efferent portion of the reflex arch of the trigeminal nerve. Generally temporary, it typically resolves in less than 2 weeks time, yet permanent cases may occur. Trismus may interfere with normal speech and eating, including the ability to swallow normally.
