Abstract
Introduction The management of maxillofacial trauma can be challenging in different unique clinical presentations. While maxillofacial fractures vary in location based on the mechanism of injury, the mandibular fracture is noted to be one of the most common facial fractures. The objective of this study was to explore the differences in injury patterns, outcomes, and demographics of isolated traumatic mandibular fractures between incarcerated and general populations. Methods This retrospective study analyzed consecutive patients presenting for trauma care from January 1, 2010, to December 31, 2020, at the Arrowhead Regional Medical Center (ARMC). Patients 18 years and older were included in this study. Patients diagnosed with mandibular fracture as the primary diagnosis at admission and discharge were identified using the International Classification of Disease, Ninth and Tenth Revision (ICD-9, ICD-10) Code. Patient demographics were extracted from their electronic medical records and included race, marital status, and insurance status. Results A total of 1080 patients with confirmed mandibular fractures were included in the final analysis. Among these patients, 87.5% (n=945) were males, 40% (n=432) of the patients were Hispanic, and the average age was 31.55 years old. The most common mechanism of injury was blunt trauma secondary to assault. Compared to the general population with mandibular fracture, the incarcerated patients with mandibular fracture were more likely to be males (96.1% vs 86.1% for incarcerated population vs. general population respectively, p=0.0005). No other variables were statistically different between these two groups. Conclusion The evidence from this study suggests that the patterns, outcomes, and demographics of mandibular fracture in both incarcerated and general populations are similar.

J Maxillofac Oral Surg 2024; 23:107-113. [PMID: 38312972 PMCID: PMC10830940 DOI: 10.1007/s12663-022-01817-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Accepted: 10/31/2022] [Indexed: 11/18/2022] Open
Abstract
The aim of this study was to compare the stability and clinical outcomes between the two miniplates and sagittal split plate (SSOP) in angle fracture fixation. Thirty-eight patients with a mandibular angle fracture were selected and divided randomly into two groups. Intervention was treated with SSOP, and the control group was treated with conventional two miniplates. Clinical evaluation included occlusion, edema, nerve affection, wound dehiscence and mouth opening. Radiographic parameters included the measurement of inter-ramus distance, inter-mental distance and bone density. All clinical parameters were evaluated at one week, one month and three months intervals. Radiographic parameters were evaluated immediately postoperative, and after three months. Results showed that SSOP had less postoperative complications (10.50%) than the two miniplates (31.60%). It can be concluded that both methods offered high performance in management of mandibular angle fractures. However, SSOP group had a significantly shorter operating time, increased bone density and less edema. Clinical trial registration number: NCT03839368.

Abstract
Background The primary objectives of mandibular surgery are to achieve optimal occlusion, low sensory disturbance, and adequate fixation with early movement. In-depth knowledge of the mandibular structure is required to achieve these goals. This study used computed tomography (CT) to evaluate the mandibular cortical thickness and cancellous space according to age and sex. Methods We enrolled 230 consecutive patients, aged 20 to 50 years, who underwent CT scanning. The cortex and cancellous space centered around the inferior alveolar nerve (IAN) canal were measured at two specific locations: the lingula and second molar region. Statistical analysis of differences according to increasing age and sex was performed. Results The t-test revealed that the cancellous space and cortical thickness differed significantly with respect to the threshold of 35 years of age. Both cortical thickness and cancellous space in the molar region were negatively correlated with age. Meanwhile, both cortical thickness and cancellous space in the lingula region showed a positive correlation with age. With respect to sex, significant differences in the cancellous space at the molar region and the cortical thickness at the lingula were observed. However, no further statistically significant differences were observed in other variables with respect to sex. The sum of each measurement on the mandibular body reflected the safe distance from the surface of the outer cortex to the IAN canal. The safe distances also showed statistically significant differences between those above and below 35 years of age. Conclusion Knowledge of the anatomical structure of the mandible and of changes in bone structure is crucial to ensure optimal surgical outcomes and avoid damage to the IAN. CT examination is useful to identify changes in the bone structure, and these should be taken into account in the planning of surgery for older patients.

Abstract
INTRODUCTION Mandibular angle fractures are very common and are associated with the highest risk of complications. The aim of this study is to evaluate the correlation between impacted lower third molar and mandibular angle fracture complications. MATERIAL AND METHODS All patients presenting with a mandibular angle fracture and at least 2 months follow up were retrospectively included. The following complications were recorded: post-traumatic malocclusion, mouth opening limitation, inferior alveolar nerve hypoesthesia, infection, delayed union, hardware loosening. The patients were divided in two groups: impacted lower third molar or erupted/absent lower third molar. RESULTS A total of 68 patients were included, lower third molar was impacted in 36 cases and erupted/absent in 32 cases. 40 complications were recorded in 27 patients at 2 months. No statistically significant difference could be found about malocclusion, mouth opening limitation and inferior alveolar nerve hypoesthesia. A lower rate of persistent inferior alveolar nerve hypoesthesia (p = 0.0557) in patients with impacted lower third molar (19.4%) was observed compared to patients without impacted lower third molar (40.6%). There was no occurrence of delayed union and hardware loosening in impacted lower third molar group, whereas 5 delayed unions and 4 hardware loosening were recorded in erupted/absent lower third molar group. Finally, the rate of patients with at least one of the 6 complications is significantly higher in the erupted/absent lower third molar group (17/32, 53.1%) than in the impacted lower third molar group (10/36, 27.8%), p = 0.033. DISCUSSION The risk of overall complication is decreased when lower third molar is impacted in mandibular angle fracture. This supports the idea of a role of the impacted lower third molar in fracture reduction and stability.

Abstract
OBJECTIVES To provide evidence based guidance on the optimum prophylactic antibiotic prescribing regimens in the treatment of fractured mandibles to protect against surgical site infections. MATERIAL AND METHODS OVID and Pubmed databases were searched for articles published between 1946 and 2020. Inclusion criteria was for articles to be in English, involve adult patients aged 14 and over, and involve patients treated with oral or IV antibiotics preoperatively, perioperatively or postoperatively during treatment of open or closed fractures of the mandible. Exclusion criteria included infected fractures on presentation, immunocompromised patients, fractures resulting from gunshot and pathological fractures. RESULTS A number of retrospective and prospective, randomised, double blind placebo-controlled trials were identified as suitable for inclusion. The age range within these trials was 14-77 years old. The numbers of patients contained within each trial ranged from 30 to 642. The most commonly prescribed antibiotics were penicillin, administered orally or intravenously. Duration of administration ranged from hospital admission to five days postoperatively. Analysis of these studies failed to demonstrate a statistical difference on the number of surgical site infections and the duration of antibiotic course. CONCLUSIONS The available evidence reveals no statistical difference in infection rates whether antibiotics are prescribed pre, peri, or postoperatively. The duration of antibiotics therapy also appears not to be important. Current evidence does not support the recommendation of an optimum antibiotic prescribing regimen. Additional prospective studies looking at the duration and timing of antibiotics during the management of fractured mandibles are required to identify the optimum prescribing regimen.

Abstract
In recent years in the field of biomechanics, the intensive development of various experimental methods has been observed. The implementation of virtual studies that for a long time have been successfully used in technical sciences also represents a new trend in dental engineering. Among these methods, finite element analysis (FEA) deserves special attention. FEA is a method used to analyze stresses and strains in complex mechanical systems. It enables the mathematical conversion and analysis of mechanical properties of a geometric object. Since the mechanical properties of the human skeleton cannot be examined in vivo, a discipline in which FEA has found particular application is oral and maxillofacial surgery. In this review we summarize the application of FEA in particular oral and maxillofacial fields such as traumatology, orthognathic surgery, reconstructive surgery and implantology presented in the current literature. Based on the available literature, we discuss the methodology and results of research where FEA has been used to understand the pathomechanism of fractures, identify optimal osteosynthesis methods, plan reconstructive operations and design intraosseous implants or osteosynthesis elements. As well as indicating the benefits of FEA in mechanical parameter analysis, we also point out the assumptions and simplifications that are commonly used. The understanding of FEA's opportunities and advantages as well as its limitations and main flaws is crucial to fully exploit its potential.

Abstract
The aim of the present study is to assess the reliability and accuracy of different 3-dimensional (3D) reconstruction algorithms in detecting undisplaced condylar, zygomatic arc, and orbital rim fractures based on cone-beam computed tomography data set. Twenty sheep heads were used in the present study. Sixty fractured and 60 nonfractured (control) zones were randomly allocated. Three groups consisting of nondisplaced fractures of condyle (CF, n = 20), orbital (OF, n = 20), and zygomatic arc (ZF, n = 20) were created by using a diamond cutting disc. Soft tissues were only dissected and no fractures were generated in the control group (n = 60). The 3D reconstructions were created by using multiplanar reconstruction (MPR), surface rendering (SR), volume rendering (VR), and maximum intensity projection (MIP) algorithms. Final 3D models were examined in Osirix software (Pixmeo SARL, Bernex, Switzerland) by 6 observers. Diagnostic accuracies of each algorithm were statistically compared by receiver operating characteristics (ROC) and area under the ROC curves (AUCs). For the detection of CF, AUC for VR algorithm was found to be statistically larger than that of MIP while AUCs for VR and MIP were larger than those of MPR and SR for OF detection. For the detection of ZF, AUCs for MPR and VR were significantly larger than those of MIP and SR (P < 0.05 for each). Within the limitations of this experimental study, it can be concluded that for maxillofacial surgeons, it is more likely to detect condylar, orbital, and zygomatic fractures by using VR algorithm in 3D reconstruction.

Abstract
Biodegradable magnesium alloys are suitable osteosynthesis materials. Despite the alloy composition, surface modifications appear to have an influence on the degradation process and biocompatibility. The aim of this study was to investigate the impact of hydrogenation and fluoridation of the surface in a mandibular osteotomy model. Standard-sized plates and screws were implanted in an osteotomy at the mandibular angle in nine miniature pigs. The plates and screws were harvested together with the adjacent tissues at 8 weeks after surgery and were investigated by micro-computed tomography and histological analysis. The bone healing of the osteotomy was undisturbed, independent of the surface properties. The adjacent bone tissue showed new bone formation at the implant surface; however, formation of some lacunae could be observed. The corrosion was between 9.8% and 11.6% (fluoridated<hydrogenated<non-modified) in histological specimens, while radiologically neither the volume nor the density of the osteosynthesis material was reduced in any treatment group. The soft tissues exhibited full biocompatibility with every surface property. In summary, surface modification by hydrogenation and fluoridation did not significantly influence bone healing, biocompatibility, or corrosion kinetics of the magnesium osteosynthesis at the mandibular angle.
