This produces pain which causes further anxiety which in turn causes prolonged muscular spasm at trigger points, vasoconstriction, ischemia and release of pain mediators. The pain discourages use of the masticatory system (a similar phenomenon in other chronic pain conditions is termed "fear avoidance" behavior), which leads to reduced muscle ...
Sometimes mandibular fractures in the region of the angle of the mandible may cause an infection of the submasseteric space. [1] The signs and symptoms of a submasseteric abscess may include marked trismus (i.e. difficulty opening the mouth, since the masseter elevates the mandible and it becomes restricted) and swelling in the region of the ...

[6] Another definition of trismus is simply a limitation of movement. [4] Historically and commonly, the term lockjaw was sometimes used as a synonym for both trismus [2] and tetanus. [7]
The pain may be felt over the angle of the jaw (masseter) or in the temple (temporalis), and may be described as a headache or an aching jaw. Most (but not all) bruxism includes clenching force provided by masseter and temporalis muscle groups; but some bruxers clench and grind front teeth only, which involves minimal action of the masseter and ...
These may include the thick muscle in the cheek that closes the jaw (masseter muscle) and the broad muscle that draws back the lower jaw and closes the mouth (temporalis muscle). Some patients may also experience involuntary contractions of the wide muscle at the side of the neck (platysmal muscle). This muscle draws down the corner of the ...
