Trismus caused due to muscle rigidity. Diagram of jaw muscles are shown here.
Trismus is a condition of restricted opening of the mouth.[1][2] The term was initially used in the setting of tetanus.[2] Trismus may be caused by spasm of the muscles of mastication or a variety of other causes.[3] Temporary trismus occurs much more frequently than permanent trismus.[4] It is known to interfere with eating, speaking, and maintaining proper oral hygiene. This interference, specifically with an inability to swallow properly, results in an increased risk of aspiration. In some instances, trismus presents with altered facial appearance. The condition may be distressing and painful. Examination and treatments requiring access to the oral cavity can be limited, or in some cases impossible, due to the nature of the condition itself.
