Active clinical trials for "Trismus"

In dentistry, one of the most common surgical procedures is the removal of included third molars. This surgery generates great morbidity to patients for causing pain, edema and trismus due to surgical trauma. The use of photobiomodulation (PBM) (low-power laser or light emitting diode - LED) in the postoperative of these procedures has shown excellent results in the control of postoperative sequelae. The objective of the present study is to evaluate the effectiveness of PBM with LED in the control of pain, facial edema, trismus and quality of life resulting from the extraction of retained lower third molars. A randomized, double-blind, placebo-controlled clinical trial involving 34 adult patients, who search the Discipline of Buccomaxillofacial Surgery and Traumatology (CTBMF) II of FO-UFRGS for the removal of included lower third molars will be conducted. Before and after the surgeries, the facial and mouth opening measurements of all patients will be done. Immediately after the surgeries, the patients will be randomized by means of envelopes in two groups. In the LED group the patients will receive daily LED applications (intra oral with 660nm and extra oral with 850nm) from the immediate postoperative to 7 days after the surgical procedure. In the control group the patients will be treated in the same way as in the LED group, however, the person in charge of the application will simulate intraoral and extraoral irradiation with the LED kept off. Pain (EVA and NRS-101), postoperative edema, trismus, temperature, dysphagia and hematomas, as well as the impact of the surgical procedure on patients' quality of life will be evaluated after 1, 2, 5 and 7 days. For the analysis of the oral health impact profile (OHIP-14 Questionnaire) and anxiety analysis (Beck anxiety inventory -BAI) the questionnaires will be applied preoperatively and 7 days after treatment. Initial descriptive analyzes will be performed considering all variables measured in the study, both quantitative (mean and standard deviation) and qualitative (frequencies and percentages). Later, the appropriate statistical tests will be applied for each specific analysis. In all tests, the significance level of 5% probability or the corresponding p-value will be adopted. All analyzes will be performed using the statistical software SAS for Windows, version 9.1.3.

In this study; Among the patients randomized because of severe postoperative sequelae expected as a result of radiological and clinical examinations; nonsteroid antiinflammatory drug prescribed group compared with preoperative single dose intraoral submucosal corticosteroid administration and therapeutic elastic bandage application considering inflammatory symptoms' severity and health related quality of life following surgical removal of impacted third molars. The study hypothesis was formed stating that corticosteroid injection and elastic bandage application would reduce the inflammatory symptoms more than NSAID.

Trismus (limited jaw mobility), can occur in patients undergoing radiotherapy to specific areas of the head or neck. Trismus leads to difficulty in eating, swallowing, speech and general mouth hygiene, which all have negative effects on quality of life. Research in the area of trismus is limited; it is not known exactly when trismus develops, one study suggests that some patients have experienced a diminished opening at as low doses as 15 Gy. Literature suggests benefits of a training programme, but there is a lack of evidence to support the use of a training programme during radiotherapy. The purpose of this study is to investigate the effectiveness of a training programme during and after radiotherapy, and report the incidence of trismus in patients who receive radiotherapy to the jaw muscles. The study also investigates quality of life during radiotherapy and up to one year after completed treatment. Patients who meet the criteria and give their consensus to the study are divided into two groups: Group 1: Training with TheraBite Jaw Motion Rehabilitation System, which is a portable system utilizing repetitive passive motion and stretching to restore mobility and flexibility of the jaw musculature. Individuals train five times a day. Group 2: Conventional treatment (jaw measurements once a week). If the individuals jaw mobility decreases 15% from the original start measurement, the patient is automatically offered a trainings program (as in group 1). During radiation therapy a hospital specialist dentist measures the jaw mobility once a week, thereafter at 3,6,12 months after completed Radiation Therapy. On 5 different occasions the patients are requested to complete a Quality of life questionnaire. Patient's record their training frequency in a log book.

A monocentric Study to evaluate the french translation of Gothenburg Trismus Questionnaire (GTQ).

Trismus is an involuntary contracture of the masticatory muscles, blocking the opening of the jaw, first intermittent then permanent and irreducible. Trismus is the result of pain or spasm or even muscle fibrosis, due to infectious, inflammatory or tumoral involvement of the masticatory muscles. During any anesthesia, control of the patient's upper airways is a major issue. Orotracheal intubation is the gold standard. Trismus will therefore complicate this management of the airways. This trismus can prevent the realization of a classic intubation, by the inability to use a laryngoscope or video laryngoscope, in favor of awake fiberoptic intubation, a technique that causes discomfort during the procedure, then a state of post-traumatic stress. Mandibular block is increasingly used in the analgesia of mandibular surgeries thanks to the simplicity of the technique and its good efficiency. It has been described that the mandibular locoregional anesthesia made it possible to remove the trismus due to a dental infection, allowing the realization of a surgical gesture under good conditions. In addition, authors have described V3 block as a technique that could improve the safety of anesthesia in patients with acute trismus, by avoiding the need for awake nasofibroscopy intubation. One study showed that performing locoregional anesthesia of the mandibular nerve improved the mouth opening in patients with mandibular fracture. The investigators wondered if this locoregional anesthesia could also work on other types of trismus such as infectious, tumoral and osteoradionecrosis trismus. During preoperative consultation, anesthesists usually measure the mouth opening. In our study, anesthesists will also measure the mouth opening after performing locoregional anesthesia of the V3 nerve (mandibular block). In addition to the measurement made before the start of the anesthetic treatment, research provides for three other measurements of the mouth opening using a rule (millimeters), taken at different times : after sedation, after performing locoregional anesthesia and after curarization. The investigators will also collect the cause of the limited mouth opening, the duration of development. The investigators will study pain at rest and when opening the mouth, under sedation, when performing the block, then when opening the mouth after performing the block. The presence of edema next to the area of locoregional anesthesia, the type of product used for sedation and locoregional anesthesia, the intubation technique performed, as well as the difficulty experienced by the operator will be collected

If the patients's teeth are weak or the mouth dose not open well, the lightwand is a useful device when endotracheal intubation is necessary. Therefore, if the appropriate position of the light beam is determined and the distance of the light source suitable for intubation using the lightwand is obtained from anatomical structures such as thyroid cartilage and cricoid cartilage, it is clinically useful. Because it can prevent unnecessary deep insertion or shallow insertion that can cause damage to anatomical structures during intubation.

this study was planned to investigate the antiinflammatory activity of preemptive intravenous ibuprofen on inflammatory complications such as edema and trismus after third molar tooth surgery

Background: The aim of this study is to develop a prediction model for radiation-induced trismus (maximal interincisal distance equal to or less than 35 mm) based on a multivariable analysis of dosimetric and clinical factors.

This study aims at evaluating the prevalence of trismus among maxillary cancer patients in the Egyptian population and the effect of radiotherapy on the occurrence of trismus.
