Randomized Controlled Trial Comparative StudyA randomized clinical trial of the effects of submucosal dexamethasone after surgery for mandibular fractures.
To evaluate the effects of immediate postoperative submucosal dexamethasone administration on postoperative pain, edema, trismus, and mandibular functions after open reduction and internal fixation (ORIF) for mandibular fractures. ⋯ The results of our study suggest that submucosal administration of dexamethasone after ORIF for mandibular fractures is effective in reducing postoperative pain and edema.

Management of comminuted but continuous mandible defects after gunshot injuries.
Firearm injuries continue as a major public health problem, contributing significant morbidity, mortality, and expense to our society. There are four main steps in the management of patients with gunshot wounds to the face: securing an airway, controlling haemorrhage, identifying other injuries and definitive repair of the traumatic facial deformities. The objective of this study was to determine late outcome of two treatment options by open reduction and internal fixation versus closed reduction and maxillomandibular fixation (MMF) in the treatment of gunshot injuries of the mandible. ⋯ Based on this study open reduction and internal fixation is the best available method for the treatment of gunshot mandible fractures without continuity defect.

Ropivacaine via trans-cricothyroid membrane injection inhibits the extubation response in patients undergoing surgery for maxillary and mandibular fractures.
Extubation response can lead to cardiovascular and respiratory complications. Here, we aimed to evaluate the effect of ropivacaine injected via the trans-cricothyroid membrane on the extubation response. This prospective, double-blind, randomized study included 70 patients classified as American Society of Anesthesiologists status I-II, who required general anesthesia with nasotracheal intubation for maxillary and mandibular fracture surgery; patients were divided into the ropivacaine (20 mg) and dicaine (20 mg) groups. ⋯ The number of patients with grade 1 or 2 cough was significantly higher in the dicaine group than that in the ropivacaine group (P < 0.05). There was no significant intergroup difference in the rate of postoperative complications (P > 0.05). These results suggest that the administration of ropivacaine via trans-cricothyroid membrane injection can effectively inhibit the extubation response.

Randomized Controlled Trial Comparative StudyComparative evaluation of 2.0-mm locking plate system vs 2.0-mm nonlocking plate system for mandibular fracture: a prospective randomized study.
This study evaluated the efficacy of a 2.0-mm locking plate/screw system compared with a 2.0-mm non-locking plate/screw system in mandibular fractures. A prospective randomized clinical trial was conducted. Patients were randomly assigned to receive 2.0-mm locking plates (group A) or 2.0-mm nonlocking plates (group B). ⋯ Two complications occurred in the locking group and five in the nonlocking group with complication rates equalling 6% and 13%, respectively. When comparing the overall complication rates according to plates used, the χ(2) test showed no statistically significant difference between the locking and nonlocking plates (p > 0.05). In conclusion, mandible fractures treated with 2.0-mm locking plates and 2.0-mm nonlocking plates present similar short-term complication rates.

Randomized Controlled Trial Multicenter StudyOpen reduction and internal fixation versus closed treatment and mandibulomaxillary fixation of fractures of the mandibular condylar process: a randomized, prospective, multicenter study with special evaluation of fracture level.
This randomized, clinical multicenter trial investigated the treatment outcomes of displaced condylar fractures, and whether radiographic fracture level was a prognostic factor in therapeutic decision-making between open reduction and internal fixation (ORIF) versus closed reduction and mandibulomaxillary fixation (CRMMF). ⋯ Fractures with a deviation of 10 degrees to 45 degrees, or a shortening of the ascending ramus >or=2 mm, should be treated with ORIF, irrespective of level of the fracture.
