View clinical trials related to Mandibular Fractures.
Filter by:Mandible fractures are a common cause of facial injury in adults. The autologous mesenchymal stem cell (AMSC) transplantation, is proposed as an alternative to the conventional graft treatment, improving bone neoformation.The objective was to evaluate the effectiveness of AMSCs application in mandibular fractures to reduce regeneration time and increase bone quality.
The sensory innervation of the face depends on the trigeminal (fifth cranial) which is divided into three branches, the mandibular nerve (V3) having motor fibers to the temporal and masseter muscle. The regional anesthesia of the face has grown in recent years for performing certain actions under light general anesthesia or sedation. The mandibular block is a simple and reliable technique but little used. Yet it reduces postoperative pain sagittal osteotomy of the mandibular branch by reducing consumption of opioids and in the oropharynx cancer surgery. Made with ropivacaine, known for its vasoconstrictive action, it also improves the visibility of the operative field during mandibular osteotomies reducing bleeding. Despite a real clinical benefit (ease of implementation, latency and duration of action of the local anesthetic), the V3 block ropivacaine is not evaluated in the maxillofacial surgery.
A new surgical approach, denoted as the supratemporalis approach, was designed to treat diacapitular condylar fractures of the mandibular condyle.This approach prevented facial nerve injury and did not increase the frequency of other complications. Therefore, the investigators suggest this surgical procedure as a routine and safe approach to diacapitular condylar fractures, which can also be applied to temporomandibular joint（TMJ）and to the zygomatic arch.
Mandibular fractures represent approximately 50% of the total facial fractures and are commonly (more than half) presented in more than one location. A few simple fractures can be treated using a conservative approach. More often, however, mandibular fractures require stabilization using open reduction and internal fixation. Simple mandibular fractures can be treated using non-rigid fixation techniques that rely on the load-sharing principle, by which stabilization is accomplished with both fixation devices and bone surfaces. On the other hand, more complex fractures with continuity defects or comminuted need to be handle using rigid fixation where the device assumes all the forces (load-bearing principle). These approaches are well established, whereas the level of evidence for the treatment of bilateral double mandibular fractures (DMF) is still scarce. In fact, which surgical treatment, or combination of treatments, leads to the best outcome and the lowest rate of complications in bilateral DMFs is an open question. The purpose of this study is to assess the complication rate in patients suffering from bilateral DMF treated either using non-rigid fixation on both fracture sides or a combination of rigid fixation on one side and non-rigid fixation on the other side.
Patients who sustain a fracture of the lower jaw are typically treated by wiring the teeth together or using small titanium plates and screws to fix the fracture. With either technique the upper and lower teeth are held together to ensure that the fracture is held in the correct position during healing (for closed reduction) or while the plate and screws are applied (for open reduction). The teeth can be held together using Erich arch bars which are a type of braces that are temporarily wired to the existing teeth. These stay in place for 6 weeks until the fracture has healed even though the patient is able to open his mouth immediately after the surgery is complete. The alternative to the traditional Erich arch bars is a relatively new type of arch bar (Stryker Hybrid) that is screwed to the jaw bone rather than wired to the teeth. The purpose of this study is to compare the two types of arch bars in terms of the speed with which they can be applied as well as any difference in fracture healing
The mandible bears a wide range of mechanical load from the contraction of masticatory muscles, and has a significant function in normal chewing movements. Mandibular fractures are the most common maxillofacial fractures, accounting for 40%-71% of all maxillofacial fracture cases with an average of 62%. The etiology of mandibular fractures mainly includes assaults, road traffic accidents (RTAs), falls, and sports injuries. Although a wide variance exists in the reported percentage of anterior mandible fractures, aggregate analysis approximates these fractures at 17% of all mandibular fractures. The rigid internal fixation (RIF) technique has become a common treatment for mandibular fractures, in which titanium plates are used in the operation. Some patients have to remove the titanium plates in a second operation following bone healing because of sequelae, such as stress shielding. Biodegradable plates and screws have been developed to eliminate the problems associated with titanium fixtures. In this study, we aim to compare the clinical performance between biodegradable and titanium fixation systems after 12 months of follow-up in fixation of mandibular symphysis and parasymphysis solitary fractures. We also investigate the stress distributions of biodegradable and titanium fixation systems at mandibular symphysis solitary fracture on the conditions of intercuspal position, labial teeth occlusion, and premolar and molar occlusion using finite element analysis.
Introduction After a mandibular fracture where bone has been lost, a number of complications and challenges are presented in trying to solve them. These defects are mainly classified into two groups: functional and cosmetic. The functional defects are incompetence of the lower lip, salivary incontinence, severe difficulty chewing and swallowing, temporomandibular joint disorders and difficulty in pronouncing words. Esthetically facial asymmetry is produced with collapse of the affected side. Unreconstructed jaw retrusion and tends to offset the affected side, there is a change in mandibular movements, which, previous vertical movements are replaced by oblique or diagonal movements controlled by a single temporomandibular joint. It also presents a limitation in motility and lingual force, besides proprioception disorder left by the inferior alveolar nerve The loss of bone in mandibular fractures, is one of the great challenges facing maxillofacial surgery and unfortunately increasingly common. That's why they have done and are still doing research for the development of biomaterials, all with the purpose of trying to solve this problem by offering the patient better results than those obtained in the past, restoring both function and facial aesthetics according to each case
Determining the cost effectiveness of two methods of wiring the jaws together during surgery to repair mandible fractures. One technique is more expensive but faster in application, while the other is less expensive and takes more time to apply.
Facial fractures make up a significant proportion of injuries in trauma patients. Treatment of these fractures often results in standard surgical interventions. While up to the early 1980's perioperative antibiotic prophylaxis in maxillofacial surgery was controversial, its efficacy is well accepted today. Chole and his team could show that the administration of antibiotics one hour preoperatively and eight hours after the intervention reduces the incidence of infectious complications in facial fractures from 42,2% to 8.9%. However there is still no consensus about the duration of the postoperative administration. In literature postoperative prophylaxis in facial fractures varies from single-shot 6-7 up to a duration of 7 and even ten days postoperatively 8-10. The use of antibiotics can be associated with allergic or toxic reactions, adverse effects, drug interactions and increasing bacterial resistance. In addition some authors assume that a prolonged administration of antibiotics might increase the risk of infectious complications via superinfection. On the other hand a short term or single shot administration might not be enough to prevent the onset of an postoperative infection. Up to date there is no standard to support the administration of antibiotics after surgical repair of a facial fracture. The purpose of this prospective, randomized double-blinded trial is to investigate the utility of antibiotics administered in the postoperative period after surgical revision of facial fractures. Hypothesis: a short-term antibiotic prophylaxis of 1 day postoperatively is equally effective as a long-term administration of 5 days in facial fractures.
