The use of resorbable plates in association with dental arch stabilization in the treatment of mandibular fractures in children.
The purpose of this study was to investigate the effect of resorbable plate fixation in association with dental arch stabilization in the treatment of displaced mandibular fractures in children. ⋯ Resorbable plates use in association with dental arch stabilization can provide good stabilization for mandibular fractures and is a promising approach for the treatment of displaced mandibular fractures in children.

The osteogenic activity of human mandibular fracture haematoma-derived cells is stimulated by low-intensity pulsed ultrasound in vitro.
Low intensity pulsed ultrasound (LIPUS) stimulation is a clinically established treatment method used to accelerate long bone fracture healing; however, this method is currently not applied to mandibular fractures. In this study, we investigated the effects of LIPUS on human mandibular fracture haematoma-derived cells (MHCs) in order to explore the possibility of applying LIPUS treatment to mandibular fractures. MHCs were isolated from five patients. ⋯ There were no significant differences in cell proliferation between the two groups. These findings demonstrate the significant effects of LIPUS on the osteogenic differentiation of MHCs. This study provides significant evidence for the potential usefulness of the clinical application of LIPUS to accelerate mandibular fracture healing.

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.
