Dentomaxillofac Radiol 2024; 53:363-371. [PMID: 38652576 PMCID: PMC11358630 DOI: 10.1093/dmfr/twae018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 04/11/2024] [Accepted: 04/19/2024] [Indexed: 04/25/2024] Open
Abstract
OBJECTIVES This study evaluated the performance of the YOLOv5 deep learning model in detecting different mandibular fracture types in panoramic images. METHODS The dataset of panoramic radiographs with mandibular fractures was divided into training, validation, and testing sets, with 60%, 20%, and 20% of the images, respectively. An equal number of control images without fractures were also distributed among the datasets. The YOLOv5 algorithm was trained to detect six mandibular fracture types based on the anatomical location including symphysis, body, angle, ramus, condylar neck, and condylar head. Performance metrics of accuracy, precision, sensitivity (recall), specificity, dice coefficient (F1 score), and area under the curve (AUC) were calculated for each class. RESULTS A total of 498 panoramic images containing 673 fractures were collected. The accuracy was highest in detecting body (96.21%) and symphysis (95.87%), and was lowest in angle (90.51%) fractures. The highest and lowest precision values were observed in detecting symphysis (95.45%) and condylar head (63.16%) fractures, respectively. The sensitivity was highest in the body (96.67%) fractures and was lowest in the condylar head (80.00%) and condylar neck (81.25%) fractures. The highest specificity was noted in symphysis (98.96%), body (96.08%), and ramus (96.04%) fractures, respectively. The dice coefficient and AUC were highest in detecting body fractures (0.921 and 0.942, respectively), and were lowest in detecting condylar head fractures (0.706 and 0.812, respectively). CONCLUSION The trained algorithm achieved promising results in detecting most fracture types, particularly in body and symphysis regions indicating machine learning potential as a diagnostic aid for clinicians.

Abstract
Mandibular angle fractures have the greatest recorded rate of postoperative complications of any mandibular location and hence they present an especially difficult task for surgeons. Therefore, it is of interest to compare the conventional miniplates and three dimensional (3D) plates in management of mandibular angle fracture and body fractures.60 patients with isolated non-comminuted mandibular angle fractures and body fractures were randomly assigned into two groups by lottery. Utilizing Champy's osteosynthesis standards, group one (n = 30) received treatment with 2-mm standard miniplate and group two (n = 30) had treatment with open reduction and internal fixation utilizing 2-mm 3D locking stainless steel plates. The mean operative time was greater in conventional miniplate category as compared to three dimensional plates. Need for postoperative occlusion correction was lesser n 3 dimensional plate category. The incidence of postoperative infection was comparable in both categories. Incidental tooth damage was lesser in three-dimensional plate's category three-dimensional locking plates are an alternate strategy that has a comparable result profile to miniplates.

Abstract
A retrospective case-control study was performed to characterize the rate of missed follow-up appointments after facial trauma and identify associated risk factors.Follow-up appointments for facial trauma over a 3-month period at a single, safety net hospital were analyzed. Appointment-specific, sociodemographic, trauma, and management data were compared between cases (missed appointments) and controls (attended appointments). Univariate testing and multivariable logistic regression were employed.A total of 116 cases and 259 controls were identified, yielding a missed appointment rate of 30.9% (116/375). Missed appointments were significantly associated with initial clinic appointments compared to return visits (odds ratio [OR] 2.21 [1.38-3.54]), afternoon visits compared to morning (OR 3.14 [1.94-5.07]), lack of private health insurance (OR 2.91 [1.68-5.18]), and presence of midface fractures (OR 2.04 [1.28-3.27]). Missed appointments were negatively associated with mandible fractures (OR 0.56 [0.35-0.89]), surgical management (OR 0.48 [0.30-0.77]), and the presence of nonremovable hardware (OR 0.39 [0.23-0.64]). Upon multivariable logistic regression, missed appointments remained independently associated with afternoon visits (adjusted OR [aOR] 1.95 [1.12-3.4]), lack of private health insurance (aOR 2.73 [1.55-4.8]), and midface fractures (aOR 2.09 [1.21-3.59]).Nearly one-third of facial trauma patients missed follow-up appointments, with the greatest risk among those with afternoon appointments, lacking private health insurance, and with midface fractures.

Abstract
PURPOSE Currently, there are several methods of achieving maxillomandibular fixation (MMF), each with its unique operative considerations and subsequent patient outcomes and complications. In this study, we reviewed the literature to evaluate and compare all MMF methods. METHODS A systematic review of all MMF types was conducted and post-operative outcome data were analyzed and compared among the different types. Conventional Erich arch bars were compared to hybrid arch bars, MMF screws, and eyelet interdental wiring. A random-effects meta-analysis was used to determine the mean differences, and 95% confidence intervals (CIs) with a statistical significance of P < 0.05. RESULTS Among the 4234 articles identified, 24 were included, and 17 were meta-analyzed. Time to achieve MMF (-43.38 min; 95% CI, -58.20 to -28.56; P < 0.001), total operative time (-30.33 min; 95% CI, -61.05 to 0.39; P = 0.05), incidence of wire puncture injuries and glove perforations (0.11; 95% CI, 0.04 to 0.30; P < 0.001), and incidence of poor oral hygiene (0.08; 95% CI, 0.02 to 0.28; P < 0.001) were lower for alternative MMF interventions compared to those of the conventional Erich arch bars. CONCLUSIONS Alternative MMF methods required shorter operative time to achieve MMF and demonstrated other increased efficiencies of practice such as shorter total operative time and decreased glove perforations, when compared to conventional Erich arch bars. If a patient is a candidate for MMF, the presented alternative MMF techniques should be considered depending on the clinical context and availability of institutional resources.

Abstract
Successful surgical management of patients with facial fractures requires a detailed preoperative evaluation and postoperative management that differs from elective surgical patients. This review presents evidence-based recommendations from the surgical and anesthesiology literature that address many of the clinical questions that arise during the perioperative management of this group of patients. Surgeons and anesthesiologists must work together at numerous points and make joint decisions, especially where airway and pain management challenges may arise. The multidisciplinary nature of the decision-making process is emphasized.

Abstract
INTRODUCTION Complications following mandibular fractures occur in 9-23% of patients. Identifying those at risk is key to prevention. Previous studies highlighted smoking, age and time from injury to presentation as risk factors but rarely recorded other possible confounders. In this paper, we use a collaborative snapshot audit to document novel risk factors and confirm established risks for complications following the treatment of mandibular fractures. METHODS The audit was carried out by 122 OMFS trainees across the UK and Ireland (49 centres) over 6 months, coordinated by the Maxillofacial Surgery Trainees Research Collaborative. Variables recorded included basic demography, medical and social history, injury mechanism and type, management and 30-day outcome. RESULTS Nine hundred and forty-seven (947) patients with fractured mandibles were recorded. Surgical management was carried out in 76.3%. Complications at 30 days occurred 65 (9%) of those who were managed surgically. Risk factors for complications included male sex, increasing age, any medical history, increasing number of cigarettes smoked per week, increasing alcohol use per week, worse oral hygiene and increased time from injury to presentation. DISCUSSION We have used a large prospective snapshot audit to confirm established risk factors and identify novel risk factors. We demonstrate that time from injury to presentation is confounded by other indicators of poor health behaviour. These results are important in designing trial protocols for management of mandibular fractures and in targeting health interventions to patients at highest risk of complications.

Abstract
Postoperative complications following mandibular fracture treatment vary from local wound infections to severe conditions including osteomyelitis and impaired fracture healing. Several risk factors have been associated with the development healing disorders, including fracture localisation, treatment modality and substance abuse. However, limited research on the sex-specific influence of these complications exists. A total of about 300,000 female and male patients with mandibular fractures were examined in two cohorts. After matching for confounders (age, nicotine and alcohol dependence, malnutrition, overweight, anaemia, diabetes, osteoporosis and vitamin D deficiency), two cohorts were compared with propensity-score-matched patients according to outcomes (osteomyelitis, pseudoarthrosis and disruption of the wound) within 1 year after fracture. There were significant differences between female and male patients regarding the occurrence of osteomyelitis (odds ratio [OR] [95% confidence interval]: 0.621 [0.563; 0.686]) and disruption of the wound (OR [95% confidence interval]: 0.703 [0.632; 0.782]). Surprisingly, matching for the expected confounders did not change the results substantially. Sex plays a dominant role in determining the risk stratification for postoperative osteomyelitis and disruption of the wound, after accounting for other potential confounding factors. Additional research is needed to understand the underlying mechanisms and to develop sex-specific strategies to prevent these complications.

Abstract
OBJECTIVE To clarify the occurrence and causes of non-infection-related surgical wound dehiscence (SWD) in intraorally treated mandibular fractures. MATERIAL AND METHODS Patients with one or two fractures of the dentate part of the mandible treated surgically via an intraoral approach were included in this retrospective study. The primary outcome variable was SWD. Associations between patient-, fracture- and surgery-related variables and SWD were evaluated. RESULTS Altogether 232 patients with 270 mandibular angle, body, symphysis and/or parasymphysis fractures were included in the analysis. In all, 22 SWDs were detected. These occurred in 9.5% of patients and in 8.1% of fractures. Surgery performed at night-time showed a significantly higher SWD rate than daytime surgeries (p = .012). Additionally, a significantly greater SWD rate was found among smokers (p = .041). Other studied variables remained statistically non-significant for SWD. In a multivariate analysis, night-time was the only significant independent variable with an odds ratio of 3.297 (95% CI 1.238 - 8.780, p = .017) for SWD. CONCLUSION The approach or closure technique used and the fracture type had only a minor effect on non-infection-related SWD in patients with mandibular fractures. To avoid SWDs, mandibular fracture surgeries should be conducted during the daytime with adequate support from an experienced surgeon.

Abstract
OBJECTIVES Open repair of mandibular fractures are frequently performed surgical procedures. Increasing rates of such fractures are seen in older adults following falls. This study assesses the impact of older age on early complications following mandible fracture repair. STUDY DESIGN Retrospective analysis of national registry. METHODS The 2013-2018 National Surgical Quality Improvement Program database was queried for all cases of open mandible fracture repair and cases were categorized into younger (18-40), middle (41-65), and older (>65) age cohorts. Demographics and comorbidities were compared between the age groups. Rates of surgical, medical, and wound complications within 30-days of surgery were determined. Multivariable logistic analyses were performed to assess the relationship between age and complications. RESULTS Altogether, 1818 cases were included for analysis, of which 1269 (69.8%) were younger, 459 (25.2%) were middle, and 90 (5.0%) were older age. Increased rates of complications were seen in the older groups, including unplanned reoperation, unplanned readmission, wound disruption, and medical complications (p < 0.01). On unadjusted analysis, the older (>65) age group had an increased odds of experiencing a complication compared to the younger (18-40) group (OR: 4.19, p < 0.001). The older age group continued to have a significantly increased odds of medical complications after multivariable adjustment (adjusted OR: 8.64, p < 0.001). CONCLUSIONS On this analysis of a national database, advanced age was associated with an increased frequency of early postoperative complications following open mandibular fracture repair. Following multivariable adjustment, advanced age continued to be associated with increased odds of postoperative medical complications within 30 days of surgery.

Abstract
BACKGROUND/AIM Treatment delays in the management of mandible fractures are often unavoidable and, as a result, the timing of treatment of mandibular fractures has remained a contentious issue in clinical practice as the optimal treatment delay for minimizing complications remains unknown. The aim of this study was to determine the rate and types of complications between two cohorts of patients designated as early and late treatment groups and estimate an optimal time threshold for treatment delay after closed reduction and maxillomandibular fixation. MATERIAL AND METHODS Demographic and clinical data were collected retrospectively about patients who were treated for isolated, unilateral, favorable, and compound mandibular body fractures between 1999 and 2019 to answer the question of whether treatment delay is an independent variable impacting post-operative mandible body fracture complications. Descriptive and bivariate statistics were computed. RESULTS One hundred and seventy subjects were evaluated (n = 87 in the control/early group and n = 83 in the study/late group). The mean time lapses from injury to treatment were: early (5.8 ± 0.4 days) and late (10.3 ± 0.7 days). The overall complication rate was 14.1%. However, the complication rates of the early and late groups were 13.8% and 14.5%, respectively, with no significant difference (p = 0.89). CONCLUSIONS There was no difference between early and late treatment groups. Treatment delay was not an independent variable impacting post-operative mandible body fracture complications if treatment is done between 3 and 12 days after the injury.

Janaphan K, Hashem I, Smith C, Holmes S, Chatzopoulou D. Periodontal disease as a primary cause of surgical site infection in fractures of the mandible: is smoking a confounding variable? Br J Oral Maxillofac Surg 2022; 60:1424-1429. [PMID: 36400684 DOI: 10.1016/j.bjoms.2022.08.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 07/28/2022] [Accepted: 08/08/2022] [Indexed: 12/31/2022]
Abstract
Fractures of the mandible are common in contemporary oral and maxillofacial practice. Wound infection is the most common complication after open reduction and internal fixation, and the management of these is complex and costly in terms of morbidity to the patient, and in fiscal terms. Whilst numerous epidemiological studies implicate smoking, alcohol, drug use, and adverse behaviour, as well as fracture complexity and diabetes, as important risk factors, the role of periodontal disease is only occasionally mentioned and not formally investigated. The aim of this study therefore was to assess the presence of periodontal disease and its severity according to the 2018 EFP/AAP periodontitis case classification in patients with fractured mandibles who presented to a single level 1 trauma centre, and to look for a possible association with surgical site infection. A total of 305 patients were assessed retrospectively following open reduction and internal fixation via transoral incisions with load-sharing osteosynthesis. The postoperative infection rate was 22.95%. Multivariate and multiple logistic regression revealed that there was a strong association between periodontal staging and postoperative surgical site infection. Crucially, the study predicts that patients with severe periodontal disease (periodontal stage III and IV) are over seven times more likely to develop a wound infection than disease-negative individuals. This has implications for risk adjustment, prognostication, treatment planning, and postoperative care. Surprisingly in this study, cigarette smoking, an established risk factor in the pathogenesis of periodontal disease, did not achieve statistical significance, potentially conflicting with the established literature.

Abstract
OBJECTIVE The purpose of the study was to characterize patients who had failure of mandibular hardware (FMH). STUDY DESIGN This retrospective cohort study consisted of patients with mandible fractures (MFs) that required surgical intervention from 2012 to 2020. Patients were included when mandibular hardware failed. Descriptive variables were collected. RESULTS During the study period, 57 patients (47 male, average age 38.7 years) met the inclusion criteria. Incidence of FMH was 7.4%. Most patients were African American (n = 45, 78.9%) with American Society of Anesthesiologists classification II (n = 40, 70.2%). Tobacco use (n = 31, 54.4%) and/or alcohol (n = 33, 57.9%). The most common etiology was assault (n = 28, 49.1%). The most common location was the angle of the mandible. Most mandibles had fracture at 1 location (n = 31, 54.4%) and a tooth was involved in the fracture line (n = 44, 77.2%). More than half of patients were treated with transoral surgical approach (n = 35, 61.4%). The majority of patients received preoperative antibiotics (n = 51, 89.4%). Patients had varying levels of compliance with postoperative care, and most were not compliant. Infection (n = 45) was the most common presentation of FMH. CONCLUSION High American Society of Anesthesiologists score, smoking, excessive alcohol use, parafunctional habits, and compliance with postoperative instructions may affect surgical outcome.

Abstract
OBJECTIVE The aim is to establish the relationship between some clinical, physiological and morphological parameters in patients with the consequences of an acute injury considering the features of pathological and reparative changes in the bone fragments of the lower jaw formed during a fracture using clinical and morphological methods. PATIENTS AND METHODS Materials and methods: The material of the study was bone fragments of the lower jaw, removed during osteosynthesis operations in 20 patients with traumatic comminuted fractures. Also, the material of the study was the data obtained during the examination of the above patients. Morphological parameters characterizing the state of the fragments tissues removed during surgical treatment of fractures of the lower jaw and clinical parameters characterizing the patient's condition in cases of traumatic fractures of the lower jaw treatment were identified for frequency and correlation analysis. Different of frequency of individual indicators' gradations cases was determined by the χ-square test, correlations between parameters (correlations of pairs of parameters "clinic - morphology", "clinical and laboratory data - morphology") - by calculating the Pearson association coefficient. RESULTS Results: The main pathological and reparative changes are determined in the bone fragments of the lower jaw after a traumatic fracture: osteomedullary ischemic necrosis (traumatic bone infarction), nonspecific productive inflammation, endosteal and periosteal bone regenerates. The severity and frequency of pathological and reparative changes in the bone fragments of the lower jaw vary, leading to various correlations between clinical and morphological indicators of the fragment tissues conditions. Reliable correlations were established between individual clinical and morphological indicators of the state of bone fragments corresponding to the values of the association coefficient in the range of 0.3-0.7, in particular: in the pair "age of the patient" - "endosteal regenerates" - the dependence is negative, of medium strength, significant (p<0.05); in the pair "age of the patient" - "periosteal regenerates" - the dependence is negative, of medium strength, significant (p<0.05); in the pair "fragment surface area" - "osteonecrosis" - the relationship is negative, weak, significant with the probability of error in assessing the value |ra| p<0.1; in the pair "locus of a fracture in the lower jaw" - "type of inflammation in the bone marrow" - the dependence is positive, of medium strength, highly reliable (p<0.01). CONCLUSION Conclusions: A comprehensive clinical and morphological examination made it possible to calculate quantitative data that characterize the frequency parameters of the occur¬rence of certain pathological changes in the bone fragments of the lower jaw after a fracture and the features of individual clinical and morphological parameters conjugation in patients with the consequences of a mechanical jaw injury. The obtained data on the correlation dependences of the type "clinic - morphology" can be used to predict the severity of morphological parameters according to the known values of clinical parameters in patients with the consequences of mandibular fractures.

Abstract
Accurate evaluation, diagnosis, and management of mandibular fractures is essential to effectively restore an individual's facial esthetics and function. Understanding of surgical anatomy, fracture fixation principles, and the nuances of specific fractures with respect to various patient populations can aid in adequately avoiding complications such as malocclusion, non-union, paresthesia, and revision procedures. This article reviews comprehensive mandibular fracture assessment, mandibular surgical anatomy, fracture fixation principles, management considerations, and commonly encountered complications. In addition, this article reviews emerging literature examining 3-dimensional printing and intraoperative imaging.

Abstract
Importance: Time to surgical intervention is an oft-investigated potentially modifiable risk factor for complications after mandible fracture. Objective: To identify novel risk factors for malunion/nonunion after mandible fracture and determine the impact of treatment delay on malunion and nonunion after open reduction of mandible fractures. Design: Retrospective cohort. Setting and Participants: Encounter billing records from the New York State Inpatient Databases, State Emergency Department Databases, and State Ambulatory Surgery Databases. Patients aged 18 years and older with isolated mandible fracture in the emergency department or inpatient setting from January 1, 2006 to September 30, 2015. Main Outcomes and Measures: Mandibular Malunion/Nonunion. Results: A total of 19,152 adults were diagnosed with isolated mandible fracture. After fracture, 247 patients (1.3%) developed mandibular malunion or nonunion. In multivariable analysis, patients with open fractures (odds ratio [OR] 1.93, confidence interval [95% CI] 1.40-2.65), body fractures (OR 2.00, 1.50-2.65), alcohol abuse (OR 1.61, 1.22-2.11), diabetes mellitus (OR 1.57, 1.02-2.42), and Medicaid insurance (OR 1.46, 1.03-2.07) had increased risk, whereas patients with subcondylar fractures had reduced risk (OR 0.45, 0.28-0.72) of mandibular malunion/nonunion. The risk of mandibular malunion/nonunion after open reduction increased with treatment delay until 6-7 days after presentation (OR 1.84, 1.11-3.06). Conclusion and Relevance: Although treatment delay is often unavoidable, these findings suggest that physicians should consider early intervention in patients requiring open reduction of mandible fractures when able.

Abstract
The mandible is the most common bone to develop complications following treatment of facial fractures. This is due to a complex interaction of both fracture specific and patient factors. Our aim was to identify those patient factors, with a specific focus on those that may be potentially modifiable to reduce the incidence of complications. A systematic review of the literature was undertaken using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology to identify patient factors ascribed to an increased risk of complications following the treatment of mandibular fracture. These were divided into non- modifiable and potentially modifiable factors. A meta-analysis was performed to weight those factors for which statistical analysis had been performed. Twenty-two pertinent papers were identified, of which eight described non-modifiable and seven potentially modifiable factors. The most common potentially modifiable factor identified was smoking. Meta-analysis established that tobacco smoking demonstrated an increased risk of complications in three studies (Odds Ratio: 4.04 - 8.09). Division of patient factors into those that are potentially modifiable and those that are not will enable clinicians to focus on those in which change within the immediate postoperative period can be instigated. This includes smoking cessation assistance, education as to the need for a soft diet, and facilitating postoperative clinic attendance. It also enables stratification of risk in terms of consent, and choice of treatment. Further research should use standardised terminology, particularly in stopping the use of generalisable terms such as patient compliance and instead describing its individual components.

Abstract
The treatment of traumatic mandibular fractures constitutes a significant part of the oral and maxillofacial trauma service's workload. There are potential variations in how they are managed. Patients are often admitted and given intravenous antibiotics prior to their definitive treatment. The evidence behind this is inconclusive. We performed a systematic review as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance/ PROSPERO Registered (CRD:42020201398) on the use of antibiotics in the management of mandibular fractures. We identified studies using a search algorithm within the OVID Gateway (including MEDLINE, PubMed, and Cochrane Collaborative). Studies analysing the possible impact of prophylactic antibiotics on traumatic mandibular fractures were eligible. The primary outcome was surgical site infection requiring any treatment beyond the normal postoperative protocol. Secondary outcomes included any complication requiring further intervention. From the 16 studies identified (3,285 patients), seven were randomised controlled clinical trials (RCTs) and nine were retrospective observational studies. We have identified significant between-study variation in choice of antibiotic regimen (timing, dosage, duration) and in reporting both primary and secondary outcomes. There was significant between-study heterogeneity (p = 0.02, I2 = 69%) and none of the assessed interventions was found to be superior. The evidence behind the use of prophylactic antibiotics in mandibular fractures is weak. A properly designed and powered RCT is needed, in order to standardise practice for the benefit of patients and healthcare systems.

[PMID: 33773968 DOI: 10.1016/j.joms.2021.02.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Revised: 02/21/2021] [Accepted: 02/22/2021] [Indexed: 11/19/2022]
Abstract
PURPOSE Our level I trauma center provides care over a large geographic area including Alaska, Washington, Idaho, Montana, and Wyoming, with many patients traveling hundreds of miles to receive care. Distance to a treatment site is documented to be an independent risk factor for complications after multisystem trauma, but it is unclear if it is a risk factor for isolated mandibular fractures. The study purpose was to measure the association between distance to treatment site and risk for postoperative complications after treatment of isolated mandibular fractures. MATERIALS AND METHODS The investigators designed and implemented a retrospective cohort study and enrolled a sample derived from patients treated for isolated mandibular fractures at Harborview Medical Center by the oral and maxillofacial surgery service between June 2012 and December 2016. The primary predictor variable was distance (miles) between the patient's residence and site of treatment (Harborview Medical Center). The primary outcome variable was postoperative complication (yes or no), subcategorized as major and minor. Secondary outcome variables were time to treatment between injury and operative treatment (days) and length of hospital stay (LOS) (days). Descriptive, bivariate, and multiple logistic regression statistics were computed to measure the association between distance to treatment site and postoperative complications, time to treatment, and LOS. The level of statistical significance was set at P ≤ .05. RESULTS The study sample was composed of 403 subjects with a mean age of 32.6 ± 14.3 years and 80% were men. The average distance from the patient's residence to treatment site was 44.8 ± 128.6 miles (range, 0 to 1,440 miles; median, 20.4 miles). Major complications occurred in 11.6% of patients. The average distance between patients with and without postoperative complications was not significantly different (42.3 ± 55.8 miles vs 45.5 ± 141.7 miles; P = .8). Increasing distance was significantly associated with longer LOS (r = 0.16; P < .001) but not time to treatment (r = .04; P = .4). CONCLUSIONS In contrast to other studies regarding multisystem trauma, complications after treating isolated mandible fractures were not associated with increasing distance to treatment site. Increasing distance may be associated with longer LOS but not time to treatment.

Abstract
Objectives The objective was to compare the efficiency and assess postoperative complications of 2.00 mm unicortical locking plates and three-dimensional (3D) plates in surgical correction of uncomplicated mandibular fracture. Materials and Methods A prospective cohort study of twenty patients of uncomplicated mandibular fractures, who were operated either by noncompression unicortical 2-mm locking mini-plate or by noncompression unicortical 2-mm 3D mini-plate, were enrolled and followed up for the study outcomes such as operative time, postoperative infection, and postoperative occlusion. Results Majority of the patients (90%) were male who had road traffic accident. In 80% of cases, mandibular fracture site was parasymphysis. The mean operating time for 3D plates (43.20 min) was significantly lower than that for locking plates (54.82 min), P < 0.001. All cases operated by 3D plates compared to 60% by locking mini-plates did not need intermaxillary fixation, P = 0.025. The 80% of cases operated by 3D plates did not require postoperative occlusion correction compared to 30% in another group, P = 0.01. For other parameters such as postoperative sensory disturbance, postoperative infection, incidence tooth damage, vertical displacement of mandible, feeling of plate after platting, and chewing efficiency after 1 week, there were no statistical significant differences between the two groups. Conclusions The outcome of 2.0mm 3D mini-plate is better in terms of operating time required, post-operative need of intermaxillary fixation and occlusal correction. While the outcome is similar to the use of non-compression unicortical 2.00mm locking miniplate in parameters like infection rate and incidence of tooth damage etc.

Abstract
Regenerative paradigms exhibit nerve dependency, including regeneration of the mouse digit tip and salamander limb. Denervation impairs regeneration and produces morphological aberrancy in these contexts, but the direct effect of innervation on the stem and progenitor cells enacting these processes is unknown. We devised a model to examine nerve dependency of the mouse skeletal stem cell (mSSC), the progenitor responsible for skeletal development and repair. We show that after inferior alveolar denervation, mandibular bone repair is compromised because of functional defects in mSSCs. We present mSSC reliance on paracrine factors secreted by Schwann cells as the underlying mechanism, with partial rescue of the denervated phenotype by Schwann cell transplantation and by Schwann-derived growth factors. This work sheds light on the nerve dependency of mSSCs and has implications for clinical treatment of mandibular defects.
