Synonyms for trismus or Related words with trismus


Examples of "trismus"
Succinyl choline, phenothiazines and tricyclic antidepressants causes trismus as a secondary effect. Trismus can be seen as an extra-pyramidal side-effect of metoclopromide, phenothiazines and other medications.
Trismus is defined as difficulty in opening the mouth due to a muscle spasm resulting from a disturbance in the trigeminal nerve, 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 is derived from the Greek word "trismos" meaning "a scream; a grinding, rasping or gnashing"
Symptoms include flattening of the face, trismus (reduced opening of the jaw) and lateral subconjunctival hemorrhage.
Khanna and Andrade in 1995 developed a group classification system for the surgical management of trismus:
Historically, the term trismus was used to describe the early effects of tetany, also called "lock jaw".

Trismus may be defined as inability to open the mouth due to muscle spasm, but the term is frequently used for limited movement of the jaw from any cause and usually refers to temporary limitation of movement. Trismus can occur as a result of temporomandibular joint disorder, infection, cancer therapy, complicated extraction, arthritis, complication from a mandibular block and fractures.
Trismus, also 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.
Traditionally causes of trismus are divided into intra-articular (factors within the temporomandibular joint [TMJ]) and extra-articular (factors outside the joint, see table).
Anterior space abscess can cause trismus (spasm of jaw muscle) and hard mass formation along the angle of the mandible, with medial bulging of the tonsil and lateral pharyngeal wall. Posterior space abscess causes swelling in posterior pharyngeal wall. Trismus (spasm of jaw muscle) is minimal. Posterior abscess may involve structures within the carotid sheath, causing rigors, high fever, bacteremia, neurologic deficit, massive haemorrhage caused by carotid artery rupture.
The tumor may spread locally to soft palate and pillars, base of tongue, pharyngeal wall and hypopharynx. It may invade pterygoid muscles and mandible, resulting in pain and trismus. Parapharyngeal space may also get invaded.
Rarely, trismus is a symptom of nasopharyngeal or infratemporal tumors/ fibrosis of temporalis tendon, when patient has limited mouth opening, always premalignant conditions like oral submucous fibrosis (OSMF) should also be considered in differential diagnosis.
Signs and symptoms of a submandibular space infection might include trismus (difficulty opening the mouth), inability to palpate (feel) the inferior border of the mandible and swelling of the face over the submandibular region.
The additional symptoms include a painful throat, dysphagia, otalgia (due to cranial nerve involvement), foreign body sensation, bleeding, fixation of tongue (infiltration of deep muscles) and trismus (if the pterygoid muscle is involved in the parapharyngeal space).
Late stage symptoms can include an indurated area, paresthesia or dysesthesia of the tongue or lips, airway obstruction, chronic serous otitis media, otalgia, trismus, dysphagia, cervical lymphadenopathy, persistent pain or referred pain and altered vision.
Sims has continued to be cited for his groundbreaking work in medical textbooks, but, since the late 20th century, historians and ethicists have questioned his practices. His experimental surgeries without anesthesia on enslaved African-American women who could not consent are considered by many to be unethical. This sheds a light on the historically violent oppression of blacks and vulnerable populations in the United States. Both patients of Sims' fistula and trismus nascentium operations were not given available anesthetics, and the trismus nascentium infants whom Sims operated on perished as a result of his surgeries. In regards to Sims' discoveries, Durrenda Ojenunga wrote in 1993:
Methamphetamine users sometimes experience soreness in the joint of the jaw and dental attrition (tooth wear), owing to bruxism (grinding of the teeth) caused by the drug. This bruxism can occur continuously. Chronic use of the drug might also cause trismus, the inability to open the jaw. Long-term users often experience xerostomia (dry mouth).
Clinical signs of PEM are variable depending on the area of the cerebral cortex affected and may include head pressing, dullness, opisthotonos, central blindness, anorexia, muscle tremors, teeth grinding, trismus, salivation, drooling, convulsions, nystagmus, clonic convulsions, and recumbency. Early administration of thiamine may be curative, but if the lesion is more advanced, then surviving animals may remain partially blind and mentally dull.
Tetanus often begins with mild spasms in the jaw muscles—also known as lockjaw or trismus. The spasms can also affect the facial muscles resulting in an appearance called risus sardonicus. Chest, neck, back, abdominal muscles, and buttocks may be affected. Back muscle spasms often cause arching, called opisthotonos. Sometimes the spasms affect muscles that help with breathing, which can lead to breathing problems.
