Trismus is defined as painful restriction in opening the mouth due to a muscle spasm, [5] however it can also refer to limited mouth opening of any cause. [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]
Over time, the amount of mouth opening possible without pain can be gradually increased. A baseline record of the distance at the start of physical therapy (e.g. the number of fingers that can be placed vertically between the upper and lower incisors), can chart any improvement over time. [49]
Symptoms that may be associated with condylar resorption are both aesthetic and functional. These include: Occlusion; Anterior open bite; Receding chin; Loss of ramus height; Antegonial notching; Hyperplasia of the coronoid process of the mandible; Clicking or popping when opening or closing the jaw; Pain when opening or closing the jaw ...
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

Jaw pain Stress and grinding your teeth at night are both generally benign reasons behind why your jaw may be aching. But persistent jaw pain may also be a sign of an underlying health condition.
The inferior compartment allows for rotation of the condylar head around an instantaneous axis of rotation, [14] corresponding to the first 20mm or so of the opening of the mouth. After the mouth is open to this extent, the mouth can no longer open without the superior compartment of the temporomandibular joints becoming active.
Ask the patient to open and close whilst placing two fingers over the space of the TMJ. Opening of less than 35mm in the mandible is considered to be restricted and such restriction may be associated with intra-capsular changes within the joint. [28] Following this, ask the patient to move their jaw to the right and following this, to the left.
Trismus, a pathological condition in which the mouth is held shut by sustained spasm of the masseter (jaw) muscle, often observed in cases of tetanus; Tetanus, an infectious disease of the central nervous system; Temporomandibular joint dysfunction or TMD, often erroneously called TMJ
