Trismus Treatment
Trismus is defined as painful restriction in
opening the mouth due to a muscle spasm, however it can also refer to limited
mouth opening of any cause.Another definition of trismus is simply a limitation
of movement.Historically and commonly, the term lock jaw was sometimes used as
a synonym for both trismus and tetanus.
Trismus describes restricted range of motion of the jaw. Trismus is commonly caused by tightening or scar formation of the muscles that open and close the jaw, which prevent the mouth from opening fully. For most patients that experience Trismus Treatment either temporarily or permanently, this condition causes an inability to open their mouth greater than roughly the width of three fingers. However, some patients may develop severe trismus that can limit their opening to a finger breath or less between their upper and lower teeth.
Trismus can present as a side effect for patients who undergo surgery and/or radiation therapy in the head and neck region. The risk of developing trismus is particularly relevant for patients whose treatment area includes structures involved in or near the muscles that open and close the jaw.
Trismus, commonly called lockjaw, is reduced
opening of the jaws (limited jaw range of motion). It may be caused by spasm of
the muscles of mastication or a variety of other causes. Temporary trismus
occurs much more frequently than permanent trismus. It is known to interfere
with eating, speaking, and maintaining proper oral hygiene. This interference,
specifically with the patient's ability 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 for the
patient. 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.
Trismus is more commonly temporary than
permanent. But the earlier you start treatment, the better the chance for a
greater recovery. Use of a jaw-stretching device. These devices fit between the upper and
lower jaw. A physical therapist will tell you which stretches to perform and
how often. Studies indicate the devices may help increase the mouth opening by
5 to 10 mmTrusted Source
