    Results show a significant change in intraorbital volumes and a reduction of clinical symptoms after secondary reconstruction.

    Outcomes of this study suggest that secondary orbital reconstruction can be performed routinely using selective laser-melted PSIs and titanium spacers.

    Literature discussing palate fractures in the pediatric population is limited. We performed a retrospective review of pediatric palatal fractures at our institution to better understand the impact of this fracture pattern in the pediatric patient.

    The goal of our study is to analyze our institutional experience with pediatric palate fractures, focusing on epidemiology, concomitant injuries, and fracture management.

    Records were collected for all palatal fractures in pediatric patients diagnosed between 2000 and 2016 at an urban Level I trauma center. Patient imaging was reviewed. Demographic characteristics and inpatient clinical data were recorded.

    Nine pediatric patients were diagnosed with fracture of the bony palate. Average age was twelve with male predominance (66%). Pedestrian struck injuries (33%) and motor vehicle accidents (33%) were the most common etiologies. Five patients sustained skull fractures. Three patients were found to have intracranial hemorrhage, two required emergent bolt placement. Two patients sustained cervical spine injury. One patient had severe facial hemorrhage requiring embolization. According to the Hendrickson classification, there were three type I fractures, two type II fractures, one type III fracture, one type IV fracture, and one type V fracture. Lefort I and/or alveolar fracture was present in every patient. Four patients underwent surgical treatment with open reduction and restoration of facial height with maxillomandibular fixation. Three patients underwent concomitant mandible fracture repair.

    Pediatric palatal fractures are rare and are usually accompanied by devastating concomitant injuries. Surgical repair of the palate in the pediatric patient is often necessary to restore facial height.

    Prospective cohort study.

    Reconstruction with microvascular free flaps is quite predictable but excessive fluids intraoperatively and excessive use of vasopressors have been implicated in postoperative complications. However, vasopressors assist in limiting fluid administration and counteract vasodilatory effects of general anesthetics, while maintaining proper intravascular volume. This is of paramount importance during surgery to ensure adequate tissue and organ perfusion. The purpose of this study is to quantify perfusion changes in free flaps at specific time points during peri- and postoperative periods, incorporating SPY technology.

    A prospective study of patients who underwent free flap reconstruction was conducted (n = 9), using SPY laser angiography with indocyanine green to assess effects of general anesthetics and vasopressors on flap perfusion. Free flaps were evaluated prior to pedicle division, after inset and anastomosis, and in the immediate postoperative setting. Mean perfusion, mean arterial pressure, total operative time, fluid shifts, and vasopressor use were recorded. Data were analyzed with univariate and multivariable analyses.

    Those with major complications in this cohort, on average received less vasopressors, had shorter operation times and less blood loss, however, they received more fluids intraoperatively.

    Changes in mean perfusion to the free flap during the intraoperative and immediate postoperative period are nominal.

    There are potential substantive linkages between illicit drug use and the occurrence of injury.

    The purpose of our study was to determine the prevalence, class of illicit drugs abused, and demographics in relation to a cohort of patients who sustained facial injury.

    The authors undertook a retrospective observational study of a prospectively accessioned cohort of patients who had sustained a facial injury and presented to the John Hunter Hospital (Newcastle, NSW, Australia). The primary predictor variable was the presentation of a facial injury and the secondary outcome variables included illicit drug use, alcohol use, and socioeconomic factors. The study was carried out over a 12-month period. A descriptive analysis was undertaken on the assembled data.

    Of the 465 patient medical records that were accessed for the study, 348 were male and 117 were female. Their average age was 42.6 years 5.8% (

    = 27) were under the influence of illicit drugs at the time of their presentation and 13.1% (

    = 61) admitted to an intercurrent illicit drug habit. Those who were under the combined influence of alcohol and drugs comprised of 2.8% (

    = 13).

    Our study found that illicit drug use plays a small, but nonetheless, demonstrable role in the presentation of maxillofacial trauma patients to an urban level I trauma center. Illicit drug users are an emergent sociodemographic group of patients who can sustain facial trauma and their presentation needs to be appropriately considered, assessed, and managed collectively.

    Self-tapping and self-drilling screws are two modalities available for plate fixation. PF-04620110 manufacturer When compared to self-drilling, self-tapping screws have a few drawbacks like screw loosening, thermal osteolysis, equipment dependent, and time-consuming.

    The aim of this study was to compare the efficacy of self-tapping and self-drilling screws with relation to plate retention and stability in internal fixation of mandibular fractures using 3D finite element analysis (FEA).

    The objective of this study was to determine the influence of screw placement technique on stress concentration and deformation occurring at the screw-bone interface in self-drilling and self-tapping screws.

    A 3D computer-aided design modeling system was used to build a trilaminate mandibular bone, self-tapping screw and self-drilling screw, and a 2-holed miniplate with gap that were converted into finite element models using Hypermesh 13.0 software. Material properties and boundary conditions were assigned to these models. Pullout, torque, and torsional forces were applied to evaluate the stress concentration and deformation at the screw-bone interface.
