[Trismus, trigeminal motor dyssynergy with brain stem lesions (author's transl)].

Paradox activity of masticatory muscles was observed clinically and electromyographically in 4 patients with brain steem lesions who had trismus. There was no activity in the elevators of the jaw on the side affected during voluntary biting, as if the muscles were paralyzed. There was strong activity of the elevators on the side of the trismus on opening the mouth, inactivity on the unaffected side, or inverse activity appeared on both sides. In view of the trigeminal anesthesia on the side of paradox activation, and the absence of pyramidal signs, a stretch reflex mechanism and abolition of inhibition can not be the only basis for these phenomena; so, a disturbance of bilateral synergism, in the sense of an internuclear lesion, is postulated. In one case of motor and sensory paralysis after the extirpation of a meningioma of the cerebellopontine angle, intensive paradox activity was observed, without trismus.

Postoperative swelling and trismus after mandibular third molar removal with the lingual split bone technique.

Several factors have been suggested as possible causes for the development of the swelling and trismus which occur after the surgical removal of impacted third molar teeth. In this investigation, measurements of swelling and trismus were made before and after lower third molar removal by the lingual split technique, in a series of 53 patients. No single cause of these surgical sequelae was identified and the duration and pattern of both swelling and trismus were recorded.

Trismus after injection of local anesthetic.

Persistent pain at the site of injection is the most common complication of local anesthesia in the oral cavity. The complication of trismus after local anesthetic injection is rare and may be prevented by the use of short needles for maxillary posterior injections, and by the avoidance of multiple injections in a short period time. Once trismus develops, its progression to chronic hypomobility and fibrous ankylosis may be prevented by the early institution of treatment consisting of heat, analgesics, muscle relaxants, and exercises.

An unusual case of trismus.

Described is a case in which a patient suffered multiple facial injuries resulting in significant trismuss. Many extracapsular factors have been reported to results in trismus. Most common are those involving the coronoid process and fibrous tissue adhesions of associated structures. This case involves a situation in which multiple foreign-body fragments led to this patient's being unable to open his mouth adequately.

Effectiveness of kinesiologic tape in the management of postoperative trismus, discomfort, and edema in mandibular fractures: a randomized controlled trial.

OBJECTIVE: This study compared kinesiologic taping (KT) with conventional elastic adhesive bandaging in managing postoperative morbidity following open reduction and internal fixation. STUDY DESIGN: In this prospective, randomized controlled trial conducted at KLE Dr Prabhakar Kore Hospital, 26 patients with unilateral mandibular fractures were allocated into two groups: Group 1 received an elastic adhesive bandage (n = 13) and Group 2 used KT (n = 13). Pain (Visual Analog Scale), facial swelling (standardized linear measurements), and maximum interincisal distance were recorded at baseline and on postoperative Days 2 and 5. Data were analyzed using repeated measures ANOVA and independent t tests (p < .05). RESULTS: The KT group showed significantly lower pain scores and reduced facial edema at Days 2 and 5 compared with controls (P < .05). Trismus improved in both groups without significant intergroup differences. No adverse effects were observed. CONCLUSIONS: KT is a safe and effective adjunct for reducing early postoperative pain and edema after mandibular fracture fixation.

Inverse activity of masticatory muscles with and without trismus: a brainstem syndrome.

Clinical and EMG findings in 10 cases of intrinsic brainstem lesions are reported with paradoxical activity of jaw closing muscles during jaw opening, with and without trismus. In five cases with trigeminal anaesthesia, the inverse activity of jaw closers is interpreted as a manifestation of disturbance in the central programming of mastication in the motor trigeminal area of the brainstem. Stretch reflex mechanisms and disinhibition of the trigeminal motor neurones play no part in the origin of inverse activity. The distinct brainstem syndrome can only be detected by EMG and the special clinical features.

Bilateral surgical removal of impacted lower third molar teeth as a model for drug evaluation: a test with ibuprofen.

It was considered that double-blind crossover studies of therapeutic efficacy after acute injury could well be done in patients who required surgical removal of impacted wisdom teeth from both sides of the lower jaw. In the present trial 24 healthy patients received either placebo or ibuprofen (Brufen: 400 mg three times daily), a non-steroidal anti-inflammatory agent, for 5 days commencing the day before surgery. Treatments were given on the two occasions when impacted wisdom teeth were to be removed from one side or other of the lower jaw. A number of objective and subjective parameters were recorded for paired comparison of the post-operative courses, including swelling, trismus and pain. A mechanical device which allows simple and accurate measurement of cheek swelling is described. On the 1st, 3rd and 5th post-operative days in the ibuprofen group the measured swelling averaged 93, 89 and 82%, respectively, of that in the placebo group; the corresponding alpha-values were 0.35, 0.06 and 0.07. Patients with less swelling after ibuprofen were not always those with a high serum concentration of the drug. Ibuprofen significantly reduced pain on the day of the operation. This may at least partly account for less trismus and the preference of the patients for their post-operative courses with ibuprofen. Examination of various haematological parameters did not reveal any significant difference between the two operations. Subjective scores indicated that neither wound-healing nor bleeding was affected by ibuprofen, nor were any side effects detected.

The interrelation of postoperative complaints after removal of the mandibular third molar.

Quantitative data on pain, trismus, and swelling after removal of a mandibular third molar are presented. The population of 932 patients included both extractions and surgical removals. Frequency distributions of trismus and pain are given. For all complaints the behavior of the average value as a function of time is presented and these functions are compared with each other. For all values measured on the 3rd and 4th posttreatment days, correlation and regression coefficients for the effects were calculated. It is concluded that there exists a rather strong, but time-dependent, interrelationship between the complaints.
