Abstract
The objective of this retrospective study was to assess the bone quality of healing mandibular fracture sites by measuring the Hounsfield units (HU) on computed tomographic (CT) images obtained presurgery and postsurgery in patients treated with rigid internal fixation (RIF). The HU values of healing fracture sites were compared to those of corresponding nonfractured (control) sites on the opposing side and cervical vertebrae sites in the same patients. In total, 31 patients with 45 mandibular fractures treated with RIF underwent presurgical and postsurgical CT examinations. The scans performed after surgery (1, 3, 6, 12, or 18 months) were taken only when there was a need for radiographic evaluation due to a complaint of discomfort from the patient or when the surgeon needed to verify the postsurgical outcome, and each patient underwent only a single postsurgical CT. At the presurgical CT examination, the HU values were lower in the fracture sites than in the control sites. At 3 months postsurgery, the HU values in the fracture sites had increased as the mandibular bone healed. At 6 months postsurgery, the HU values in the fracture sites were higher than those of the control sites. At 12 and 18 months postsurgery, the HU values of both sites were similar. The HU values of the cervical vertebrae remained constant with time. These results suggest that, in patients who have been treated with RIF for mandibular bone fracture, HU values measured by CT vary across time, expressing the physiologic bone healing process.

Abstract
BACKGROUND Mandibular fractures are common facial fractures, and contemporary management of mandibular condylar fractures is controversial. The purpose of this study was to compare the outcomes of patients who sustained a mandibular condylar fracture between 2016 and 2020, who were managed by either open or closed techniques. The outcomes of this study were: post-operative facial nerve function, occlusion, and maximal mouth opening. METHODS This study is a retrospective multicentre cohort study which assessed clinical records for 246 patients with mandibular condyle fractures in three hospitals in Perth, Western Australia. The primary outcome measure was changes in post-operative facial nerve function. RESULTS One hundred and thirty-two patients underwent open reduction and internal fixation (ORIF), and 114 patients had closed management. The overall rate of temporary facial nerve injury following ORIF was 3.28%. The overall rate of permanent facial nerve injury was 0.82%. Sialocoele occurred in 2.46% of all patients who underwent ORIF. 6.14% of patients had persisting malocclusion across both groups. There was a statistically significant association between the degree of fragment shortening and facial nerve injury (P = 0.0063), with more facial nerve changes in the group with 5 mm or greater of fragment shortening. CONCLUSIONS There is still significant debate over the management of mandibular condylar injuries. This study demonstrates a similar rate of temporary and permanent facial nerve injury as previously described, as well as a similar rate of sialocoele occurrence. Further prospective studies may provide clarity about important characteristics that will help guide decision making for mandibular condylar fractures.

Abstract
PURPOSE This study investigates whether the intraoral approach to mandibular open reduction and internal fixation, through exposure to the oral cavity's microbiome, results in higher infection rates compared to the extraoral approach, thus addressing a critical public health concern, potentially offering an opportunity to reduce health-care costs, and aiming to guide effective clinical practice. METHODS In this systematic review with meta-analyses, a review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. A comprehensive literature search was conducted using Embase and PubMed for articles published between 1989 and 2023. Inclusion criteria targeted studies on open reduction and internal fixation mandibular fractures comparing intraoral and extraoral approaches and reporting infection rates. Exclusion criteria eliminated non-English articles, case reports, and studies with insufficient approach-specific data. The primary outcome was the postoperative infection rate, with surgical approach as the predictor. Covariates such as age, sex, diabetes, and smoking status were included when reported. Data were analyzed using R software, employing random-effects models due to anticipated heterogeneity (I2 statistics). RESULTS From 61 studies, 11 provided direct comparisons involving 1,317 patients-937 intraoral and 380 extraoral. Infection rates were 5.9% for intraoral and 10% for extraoral approaches. Pooled relative risk was 0.94 [95% confidence interval, 0.63, 1.39], suggesting no significant risk difference. Prevalence of infections was estimated at 9% for intraoral and 6.1% for extraoral procedures, with significant heterogeneity (I2 = 84% for intraoral and 56% for extraoral). CONCLUSION Our meta-analysis found no significant difference in infection rates between the two approaches. There is opportunity to expand on reporting complication rates comparing the various approaches to mandibular fixation. Until these data are presented, surgeon preference may dictate the operative approach to expose the mandible for reduction and fixation.

Abstract
This study aimed to evaluate the feasibility and accuracy of a combined virtual surgical planning (VPS) and short-segment drilling guides (SSDGs) workflow for the treatment of complex mandibular fractures. Consecutive patients with complex mandibular fractures underwent treatment using the VPS and SSDGs workflow from August 2020 to April 2022. Various mandibular landmarks were compared between the preoperative virtual surgical plan and postoperative data, including condylar distance (CoD), mandibular angle width (GoL-GoR), GoMeGo angle (∠GoL-Me-GoR), the difference in mandibular angles between the left and right sides (Δ∠Co-Go-Me), and the difference in length between the left and right mandibular body (ΔGo-Me). Additionally, preoperative preparation time and surgical duration were retrospectively analyzed and compared to conventional surgery. All 14 consecutive patients with complex mandibular fractures achieved successful reduction using the VPS and SSDGs workflow. Three-dimensional comparison revealed a mean deviation distance of 0.91 ± 0.50 mm and a root-mean-square deviation of 1.75 ± 0.47 mm between the preoperative designed mandible model and the postoperative mandible model. The percentage of points with deviation distances less than 2 mm, 1 mm, and 0.5 mm between preoperative and postoperative models were 78.47 ± 8.87 %, 60.02 ± 14.28 %, and 38.64 ± 15.48 %, respectively. There were no significant differences observed in CoD, GoL-GoR, ∠GoL-Me-GoR, Δ∠Co-Go-Me, and ΔGo-Me between preoperative virtual surgical planning and postoperative measurements. Furthermore, no significant differences were found in the injury-to-surgery interval, admission-to-surgery interval, and surgical duration between the workflow and conventional surgery. The combined VPS and SSDGs workflow proved to be an accurate and feasible method for treating complex mandibular fractures. It offers advantages such as minimal preoperative preparation time and the ability to precise transfer screw positions of the pre-bent reconstruction plate during surgery. This approach is particularly suitable for managing complex mandibular fractures.

Abstract
PURPOSE A randomized controlled trial was performed to evaluate the effects of light-emitting diode (LED) therapy on sensory changes in the inferior alveolar nerve after surgical treatment of mandibular fractures. METHODS Patients admitted with surgically treated mandibular fractures between January 2018 and December 2019 were evaluated. Personal data, fracture location, fracture type, and dislocation degree were obtained. The cases were randomly allocated into two groups: LED therapy (LEDT) (57 points of 660 nm and 74 points of 850 nm, 6.4 mV/cm2, and 7.64 J) with the use of a prototype device and control (CTRL). For 6 months, tactile and thermal tests were used in the mental region. Data were analyzed using the Mann─Whitney U test and likelihood ratio test (p ≤ 0.050). RESULTS The study included 42 patients, 25 of whom had bilateral fractures and 17 had unilateral fractures, totaling 67 fractures. The mean values of the tactile and thermal sensitivity tests were lower in the LEDT group in all evaluation periods. There was a significant difference between the groups in the parasymphysis location, displacement < 5 mm, and intraoral access. Sensory changes were observed in 68.7% of all fractures upon admission, with 91.2% in the LEDT group and 78.8% in the CTRL group demonstrating complete remission during the final period of the study. CONCLUSION LED photobiomodulation accelerated the process of sensory change remission. There was an influence of the fracture location, degree of displacement, and surgical access, with a better response in the LEDT group.

Abstract
This retrospective analysis aimed to investigate the necessity of removing the wisdom tooth in cases of angle fractures of the mandible. The study retrieved 595 mandible fractures from January 2006 to December 2021 through the Hospital Inpatient Enquiry System, of which 303 involved a fracture through the angle of the mandible, including the wisdom tooth socket. Of these, 203 (66.9%) underwent open reduction and internal fixation with retention of the third molar. The authors found that only four (2%) patients returned for the removal of plates and the retained third molar during the follow-up period. Therefore, the authors concluded that wisdom teeth removal should remain an exception during open reduction and internal fixation of mandibular angle fractures unless they hinder fracture reduction, pose a potential infection risk, or interfere with occlusal stability.

Abstract
OBJECTIVE This study was conducted with the aim to establish standard technique of closed reduction (CR) and compare functional outcomes in patients of moderately displaced unilateral extracapsular condylar fractures. MATERIAL AND METHODS This study is a retrospective randomized controlled trial, conducted at a tertiary care hospital setting from August, 2013 to November, 2018. Patients of unilateral extracapsular condylar fractures with ramus shortening < 7mm and deviation < 35° were divided in two groups by drawing lots and were treated by dynamic elastic therapy and maxillomandibular fixation (MMF). Mean and standard deviation were calculated for quantitative variables, and one way analysis of variance (ANOVA) and Pearson's Chi-square test were used to determine significance of outcomes between two modalities of CR. P value < 0.05 was taken as significant. RESULTS The numbers of patients treated by dynamic elastic therapy and MMF were 76 (38 in each group). Out of which 48 (63.15%) were male and 28 (36.84%) were female. The ratio of male to female was 1.7:1. The mean ± standard deviation (SD) of age was 32 ± 9.57 years. In patients treated by dynamic elastic therapy, the mean ± SD (at 6-month follow-up) of loss of ramus height (LRH), maximum incisal opening (MIO) and opening deviation were 4.6mm ± 1.08mm, 40.4mm ± 1.57mm and 1.1mm ± 0.87mm respectively. Whereas, LRH, MIO and opening deviation were 4.6mm ± 0.85mm, 40.4mm ± 2.37mm and 0.8mm ± 0.63mm respectively by MMF therapy. One-way ANOVA was statistically insignificant (P value > 0.05) for above mentioned outcomes. Pre-traumatic occlusion was achieved in 89.47% of patients by MMF and in 86.84% patients by dynamic elastic therapy. Pearson's Chi-square test was statistically insignificant (p value < 0.05) for occlusion. CONCLUSION Parallel results were obtained for both modalities; thus, the technique as dynamic elastic therapy, which promotes early mobilization and functional rehabilitation, can be favored as standard technique of closed reduction for moderately displaced extracapsular condylar fractures. This technique eases patients' stress associated with MMF and prevents ankylosis.

Abstract
BACKGROUND Mandible fracture management requires postoperative dietary modifications to promote healing. Over 20 million Americans live in food deserts, low-income neighborhoods over one mile from a grocery store. The relationship between food desert residence (FDR) and adherence to postoperative dietary instructions remains unexplored. PURPOSE This study's purpose is to evaluate the relationships between FDR, known risk factors, dietary adherence, and complications among patients with isolated mandible fractures. STUDY DESIGN, SETTING, SAMPLE This retrospective cohort study was conducted at a level 1 trauma center and analyzed patients with mandible fractures between January 2015 and December 2020. Inclusion criteria included operative treatment of adult patients for mandible fractures; pregnant, incarcerated, and patients with incomplete data were excluded. PREDICTOR VARIABLE FDR was the predictor variable of interest. FDR (coded yes or no) was generated by converting patient addresses to census tract GeoIDs and comparing them to the US Department of Agriculture Food Access Research Atlas. MAIN OUTCOME VARIABLES The study examined two outcome variables: dietary adherence and postoperative complications. Dietary adherence was coded as adherent or nonadherent, indicating documented compliance with postoperative dietary modifications. Postoperative complications were coded as present or absent, reflecting infection, hardware failure, and mandible malunion or nonunion. COVARIATES The covariates analyzed included age, sex, ethnicity, mechanism of injury, medical and psychiatric comorbidities (including diagnoses such as diabetes, hypertension, and schizophrenia), and tobacco use. ANALYSES Relative risks (RRs) and multivariate logistic regression models were generated for both outcome variables. Two-tailed P values < 0.05 were considered statistically significant. RESULTS During the study period, 143 patients had complete data allowing for FDR and dietary adherence determination, 124 of whom (86.7%) had complication data recorded. Of the cohort, 51/143 (35.7%) resided within a food desert, 30/143 (21.0%) exhibited dietary nonadherence, and 46/124 (37.1%) experienced complications. FDR was not associated with increased risk of dietary nonadherence (RR 0.92, 95% confidence interval [CI] 0.52 to 1.61, P = .76) or complications (RR 1.19, 95% CI 0.75 to 1.89; P = .46). On multivariate regression, dietary nonadherence was associated with increased complications (odds ratio 2.85, 95% CI 1.01 to 8.09, P = .049). CONCLUSION AND RELEVANCE There was no association between FDR and dietary nonadherence or complications in mandible fracture patients. However, dietary nonadherence was associated with complications, highlighting the need for further research and intervention.

Abstract
BACKGROUND Mandibular angle fractures (MAF) have a recognized complexity of treatment and an increased risk of incurring complications. METHODS This retrospective study included 45 consecutive patients who were diagnosed with an isolated MAF and no other facial fractures. The average age was 27.3 (SD = 7.7). RESULTS A comparatively low rate of complications (11.1%) and a low rate of reoperation (1.8%) are reported, along with a significant role of smoking in complications (p = 0.022). A non-significant association was noted between complications, male gender and assault as an aetiological factor. CONCLUSIONS Review of the data from this study confirms that complication rates for patients attending the National Maxillofacial Unit are similar to or better than that of international studies. An overview of the aetiology of fracture complications is included.

Abstract
BACKGROUND Scientific evidence of nonsurgical site-related complications in mandibular fracture patients is limited. PURPOSE The purpose was to measure the frequency of nonsurgical site complications in patients with mandible fractures, describe the types of complications, and identify the risk factors associated with these complications. STUDY DESIGN, SETTING, SAMPLE A retrospective cohort study was conducted at the Helsinki University hospital between 2018 and 2021. Patients undergoing surgery with open reduction and internal fixation of mandibular fracture(s) were evaluated. Patients under 16 years of age were excluded. PREDICTOR VARIABLE Primary predictor variable was age. Patient-related predictor variables were sex, long-term disease(s), smoking, and alcohol and/or drug abuse. Injury and fracture-related variables were injury mechanism, type and site of facture, combined craniofacial fracture(s), and associated injury(s). MAIN OUTCOME VARIABLE(S) The primary outcome variable was nonsurgical site-related postoperative complication. The secondary outcome variable was type of complication. COVARIATES Not applicable. ANALYSES The main outcome variable was cross tabulated for pairwise comparisons with predictor variables. Multivariate logistic regression was performed for statistically significant (P < .05) variables. RESULTS The data included 314 patients (age range: 16 to 89 years; mean age: 38 years old; median age: 33 years old); most (78.3%) were men. Nonsurgical site-related postoperative complications occurred in 6.7% of patients. The most common complication type was pulmonary complication (36.0%), followed by urinary complication (20.0%) and general infection (16.0%). Nonsurgical site-related postoperative complications were most likely to occur in patients who were elderly (adjusted odds ratio [aOR] 5.55; 95% CI 1.92 to 16.21; P = .002), had combined craniofacial fractures (aOR 2.92; 95% CI 1.06 to 8.03; P = .038), and abused alcohol or drugs (aOR 4.51; 95% CI 1.70 to 11.96; P = .003). Pulmonary complications occurred more often in elderly patients, whereas urinary complications were more common in younger patients. CONCLUSIONS AND RELEVANCE The types of nonsurgical site complications in mandibular fracture patients increase and vary according to the patient's age. Awareness of possible complications related to different age groups helps anticipate and identify these in clinical work, and to consider the overall treatment of the patient beyond the fracture.

Abstract
To investigate the role of a fully digital process in the surgical treatment of mandibular fractures in children. We analyzed a complete dataset from 22 children with mandibular fractures treated with digital surgical assistance. The patient's treatment process included preoperative thin layer CT (Computed Tomography) scanning, computer-aided design (3D reconstruction, virtual reduction, and internal fixation device determination and shaping), and 3D printing (jaw model, bite plate). We used occlusal and shaping plates during surgery to assist in fracture reduction and fixation. During the follow-up, we observed the occurrence of fracture healing, occlusal relationships, opening degrees, and complications in pediatric patients after surgery. Next, we used the 3D overlay function of MIMICS software to compare the preoperative surgical design with postoperative jaw imaging data to evaluate the overall surgical effect. The postoperative imaging data showed good fracture healing, normal occlusion during follow-up, and significant improvement in opening degrees. The mean preoperative opening degree was 23.59 ± 2.89 mm, and the mean postoperative opening degree was 29.82 ± 1.79 mm; there was a significant difference between these two parameters (p < 0.05). There were no complications such as tooth germ injury, nerve injury or fracture block displacement. The postoperative mandibular imaging data was imported into MIMICS software for 3D overlay visualization, and the postoperative mandibular morphology recovery was well-matched with the preoperative design. We measured the average upper deviation (0.65 ± 0.09) mm and the average lower deviation (-0.57 ± 0.14) mm. The fully digital process has a precise, minimally invasive, and safe effect in the surgical treatment of mandibular fractures in children, and the clinical effect is satisfactory.

Abstract
The authors describe a temporary intraoperative fixation method for the absorbable plates' fixation of subcondylar fracture by retromandibular transparotid approach. First, the fracture was temporarily fixed with a 4-hole titanium microplate across the fracture line in the center of the lateral surface of the condyle to maintain the reduction of the fracture. Then, two 4-hole absorbable mini-plates were fixed on the posterior and anterior border of the condylar neck. Finally, the 4-hole titanium microplate and screws were removed before the wound closure. In the absorbable plates' fixation of subcondylar fracture by transparotid approach, the method of temporary intraoperative fixation using a 4-hole titanium microplate offsets the limited exposure of the operative field, smooths the operation, and offers the reliability and validity of the absorbable plates' fixation.

Abstract
AIM To evaluate the benefits of a long-term prophylactic antibiotic regimen following treatment of fractured mandibles with open reduction and internal fixation. MATERIAL AND METHODS A prospective, randomized controlled trial was undertaken at Wits Oral Health Centre. Patients with mandibular fractures who were managed with open reduction and internal fixation using miniplates were randomized into 2 groups. The control group, the perioperative antibiotic (POA) group, was composed of patients who received intravenous (IV) antibiotic cover intraoperatively and a further 3 IV doses 24 hours postoperatively. The study group, the extended postoperative antibiotic (EPOA), was composed of patients who received similar doses as the control group but with an additional 5 days of oral antibiotics upon discharge. The patients were then evaluated for evidence of infection 1, 4, and 6 weeks postoperatively. RESULTS A total of 77 patients were included in the study, 41 in the POA and 36 in the EPOA groups. Fourteen patients had evidence of infection noted within the 6-week follow-up period (10 in the POA and 4 in the EPOA groups). Statistical analysis with the Pearson Chi-square and Student t test showed no statistically significant difference ( P =0.399) between POA and EPOA groups. There were no significant differences between the groups with respect to site and etiology of fracture, duration of operation, and presence of infection ( P >0.05) during the 6-week review period. CONCLUSIONS The extended use of antibiotic prophylaxis when managing mandibular fractures with open reduction and internal fixation offers no additional benefit in reducing postoperative infections.

Abstract
Condylar fracture treatment is a debated topic among maxillofacial surgeons. Various surgical techniques are used today, each one with advantages and disadvantages. The aim of this study is to present and evaluate our technique adopted for treatment of any type of extracapsular condylar fractures. Between 2020 and 2022, 16 condylar fractures were treated. In two patients with bilateral condylar fractures, the present technique was compared to the mini-retromandibular approach. All the patients were checked for clinical and radiological outcomes, facial nerve injury, scar visibility and presence of salivary complications. Dental occlusion was always restored, and facial nerve damage or salivary disorders were not observed. The skin incision, limited to the caudal two-thirds of the auricle, made the scar almost invisible and greatly improved the surgical field in the condylar neck area, facilitating the treatment. The proposed technique provides easier internal fixation for both neck and base condylar fractures with good cosmetic results, ensuring better protection of the facial nerve and parotid gland. The surgical technique described has not shown disadvantages in terms of operational difficulty, results, and complications. This novel surgical technique could represent a new choice in the treatment of extracapsular condylar fractures, although further studies are needed to support this new proposal.

Abstract
The management of mandibular fractures is routine owing to their frequency, particularly those of the mandibular condyle, which are invariably common. Notwithstanding disparities in the literature, the international consensus towards which fractures of the mandibular condyle benefit from open surgical intervention is almost universally accepted. Closed reduction or non-operative management may be utilised in certain circumstances. Whilst outcome research has addressed complications with respect to operative side effects, outcomes related to the quality of bone repair and the setting in which this is delivered have not been universally addressed. The aim of this study was to determine the predictability of translating an indicated operative treatment plan into an acceptable functional result. We evaluated the outcomes of 59 extracapsular condylar fractures in 50 patients who were treated by extraoral open reduction and internal fixation (ORIF) between March 2021 and August 2022. We reviewed demographic data, surgical approach, and plating strategy, and critically evaluated the clinical and radiological outcomes. Whilst we found that the quality of reduction was not universally perfect, the majority were within tolerance, which we set according to the Strasbourg Osteosynthesis Research Group (SORG) definition for minimal displacement (<2 mm overlap and 10° angulation). The cohort had good functional occlusion and minimal long-term postoperative complications. Two patients required re-operation for non-union, and we discuss causality in these cases. In conclusion, we found that ORIF of condylar neck and base fractures is predictable in real-time surgical practice with respect to functional outcome. However, if imperfectly reduced, there is a small risk of non-union.

Abstract
Mandibular fractures are the second most common maxillofacial fractures. The prevalent treatment for this kind of fractures is either a surgical procedure such as maxillomandibular fixation or open reduction and internal fixation or a combination of both. Sometimes the patients might develop locoregional postoperative complications. The most frequently reported complications are trigeminal V3 injury and surgical site infection. A 4-year retrospective study was performed at the Department of Oral and Maxillofacial Surgery, Policlinico Umberto I of Rome, Italy, and the postoperative complications after mandibular fracture surgical treatment were collected. The authors studied the characteristics of each complication and the correlation with the type of mandibular fracture and the surgical treatment chosen.

Abstract
Cervical necrotizing fasciitis (CNF) is a rare condition in the United States, with very few cases reported as a sequela of mandibular fracture. The authors describe the case of a 40-year-old man with poor oral health and no significant past medical history who developed CNF following delayed treatment of an open mandibular fracture, leading to life-threatening septic shock, thrombophlebitis of the internal jugular vein, and septic emboli to the lungs. Successful management of this patient was accomplished by serial surgical debridement, the administration of broad-spectrum antibiotics, and hemodynamic support. Eventual reconstruction was performed with external fixation of the mandible fracture and split-thickness skin grafting for the left neck and chest wound. The authors recommend early treatment of open mandibular fractures for immunocompromised patients or patients with poor oral hygiene to avoid the rare but potentially fatal complication of CNF and highlight external fixation as a useful technique in select cases of complex mandibular fractures.

Abstract
The goal of mandibular fracture management is to restore form and function. Maxillomandibular fixation, elastic occlusal guidance, and postoperative physiotherapy are essential elements to optimizing outcomes. Restoration of premorbid occlusion is paramount. Thus, an expert understanding of occlusion, coupled with the application of maxillomandibular techniques to achieve bony reduction with idealized dental occlusion, is required in the proper management of mandible fractures. Postoperatively, complete recovery initially requires elastic occlusal guidance followed by jaw range of motion physiotherapy. Bone healing, an idealized occlusion, and normal jaw range of motion signal success via the restoration of form and function.

Abstract
BACKGROUND/AIM Mandibular condylar fractures represent 25%-35% of all mandibular fractures. Despite profound research, there is still a controverse debate about treating these fractures conservatively or by open reduction and internal fixation (ORIF). The aim of this study is to analyse the outcome after open and closed treatment of extracapsular mandibular condyle fractures regarding general characteristics, post-treatment malocclusion, facial nerve palsy (FNP), maximum mouth opening (MMO) and parotid complications. METHODS A retrospective cohort of 377 fractures (350 open, 27 closed treatment) was reviewed by reference to clinical and radiological pre- and postoperative documentation. Follow-up period was 12 months. Pearsons' chi-square-test, correlations, Kruskal-Wallis test and t-test were carried out for statistical analysis. RESULTS The dominant type of fracture was type II in Spiessl and Schroll classification (50.1%). In the open treated fractures, the most common approach was retromandibular transparotid (91.7%). Post-treatment malocclusion occurred in 18.0% and was significantly increased in bilateral fractures (p = .039), in luxation fractures (p = .016) and in patients with full dentition (p = .004). After open reduction and internal fixation (ORIF), temporary FNP was documented in 7.1% whereas a permanent paresis occurred in 1.7%. FNP was significantly associated with high fractures (p = .001), comminution (p = .028) and increased duration of surgery (p = .040). Parotid complications were significantly associated with revision surgery (p = .009). Post-treatment reduction of MMO mainly occurred in female patients (p < .001) as well as in patients with bilateral fractures (p < .001), high fractures (p = .030) and concomitant mandibular (p = .001) and midfacial fractures (p = .009). CONCLUSION Malocclusion seems to be the most frequent long-term complication after open reduction and osteosynthesis of extracapsular mandibular condyle fractures. We suggest ORIF by a transparotid approach to be an appropriate treatment with a low complication rate regarding especially FNP for extracapsular fractures of the mandibular condyle.

Abstract
BACKGROUND Open reduction internal fixation (ORIF) of mandibular subcondylar fractures (MSF) involves several variables that could affect decision making. There is insufficient data regarding factors influencing the outcomes of MSF ORIF. PURPOSE The purpose of this study was to investigate factors associated with quality of bony reduction of MSF and occlusion, after ORIF. STUDY DESIGN, SETTING, AND SAMPLE We designed a retrospective cohort study of consecutively treated subjects for MSF ORIF, ages 18 to 64 years, by University of Illinois' Department of Oral and Maxillofacial Surgery, between January 1, 2013, and January 26, 2021. PREDICTOR VARIABLE The primary predictor variable was the vertical level of MSF from the gonial angle. Secondary predictor variables included surgeon, fixation scheme (number and configuration of miniplate), surgical approach, time to surgery, mechanism of injury, vertical fragment overlap, overlying soft tissue thickness, presence of other mandibular fractures, and severity and direction of displacement. MAIN OUTCOME VARIABLES The primary outcome variable was the mean radiographic reduction score (RRS), rated by 2 blinded observers on a 1 to 5 scale. The secondary outcome variable was presence of postoperative malocclusion as documented in the medical records. COVARIATES Covariates were age and sex. ANALYSES Descriptive statistics were computed. To investigate the influence of the predictor variables on reduction quality, multifactorial analysis of variance with post hoc Tukey test was performed. For malocclusion, χ2 test was performed. The level of significance was set at P < .05. RESULTS Thirty-eight MSF in 37 subjects were included. Mean age was 32.7 years (range 18 to 64), and 83.8% were male. Mean RRS was 4.38 (standard deviation 0.77). Fixation scheme was the only variable that showed significant impact on RRS: single-straight miniplate had lower scores than double-straight (-1.50, P = .011), rhomboid (-1.29, P = .036), and ladder miniplates (-1.38, P = .048). There was 1 incidence of malocclusion (2.7%) which resolved without intervention. CONCLUSIONS AND RELEVANCE Favorable reduction (anatomic reduction to mild discrepancies) can be achieved without malocclusion using double-straight, or rhomboid-shaped or ladder-shaped miniplates, without influences from patient or injury-related factors. In contrast, single-straight miniplate fixation resulted in moderate discrepancies in reduction, although it did not lead to malocclusion.

Abstract
The choices for managing a condylar head fracture (CHF) of the mandible are either open surgical or closed functional treatments (CFT) and the decision depends on various factors. The purpose of this systematic review was to ascertain from the available literature whether the open method or CFT yields better outcomes in managing CHF. We have systematically reviewed published articles according to the PRISMA statement. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library database for comparative studies about both open and closed treatments from inception until April 2023. The outcomes of interest were mouth opening (MO), protrusion, laterotrusion, postoperative pain, and malocclusion. Eight studies met the inclusion criteria. The review comprised of 326 cases, among which 177 were managed by open methods and 149 were treated by CFT. The incidence of postoperative malocclusion and pain were significantly less in the open group. MO was better in the open treatment group although this was not statistically significant. Protrusion and laterotrusion occurred slightly more in CFT, although these were also statistically not significant. Overall, meta-analysis favoured open methods of managing CHF. Although enough evidence exists for the use of open methods for selected condylar head fractures, CFT still demonstrated favourable outcomes in undisplaced fractures. The selection of a particular treatment method should be individualised on the basis of each particular case considering the risk/benefits. Further high quality randomised trials are needed to establish a therapeutic guideline.

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
AIM This study aimed to compare the clinical outcomes of a conventional Erich's arch bar vs a modified screw-retained arch bar in maxillomandibular fixation of mandibular fracture. MATERIALS AND METHODS This parallel-arm randomized control trial included patients from the outpatient clinic with single favorable mandibular fractures that are indicated for closed reduction. They were subjected to maxillomandibular fixation using conventional Erich's arch bars in the control group and modified screw-retained arch bars in the study group. The outcome measures included operating time, glove perforations, postoperative pain, oral hygiene, fixation stability, occlusion, and mucosal coverage. RESULTS A total of 20 patients (12 males and 8 females) with a 1:1 allocation ratio were included. There was a significant statistical difference regarding operation time and number of glove perforations in favor of group B as p < 0.001, p = 0.007, respectively. There was a significant statistical difference regarding pain after 1 day (p < 0.001), 1 week (p < 0.001) in favor of group B, and at 4 weeks (p = 0.015), and 6 weeks (p = 0.002) in favor of group A. Regarding oral hygiene at 1 week (p = 0.021) and at 6 weeks (p < 0.001), there was a significant statistical difference in favor of group B. Regarding mucosal coverage at 6 weeks, there was a significant statistical difference in favor of group A (p = 0.005). CONCLUSION The modified screw-retained arch bar can be considered an alternative to conventional arch bar as it provided less application time and better operator safety. It also showed better patient satisfaction regarding pain and oral hygiene. CLINICAL SIGNIFICANCE Maxillomandibular fixation with the conventional technique was modified to screw-retained arch bar which is less time-consuming and provides better patient and operator satisfaction.

Abstract
Our study aims to estimate the prevalence of Frey syndrome following open reduction and internal fixation (ORIF) for mandibular fractures. Two reviewers independently conducted a systematic literature search in the Medline and Scopus databases. The pooled prevalence with 95% confidence intervals (CI) was estimated, and quality assessment, outlier analysis, and influential analysis were performed. In total, fifteen eligible studies were included in this meta-analysis. One study was identified as critically influential. The overall prevalence of Frey syndrome following extraoral surgical treatment for mandibular fractures was estimated as 0.01% (95%CI 0%-0.7%) with moderate heterogeneity observed between studies. In the meta-regression analysis with continuous variables, no statistically significant association was observed. Despite the relatively low prevalence, the impact of Frey syndrome on affected individuals should not be underestimated. Additional research will provide a more comprehensive understanding of the underlying factors contributing to Frey syndrome, leading to improved preventive measures and treatment strategies. A better grasp of the prevalence and associated risk factors will aid in the development of guidelines to minimize the occurrence of this syndrome.

Abstract
OBJECTIVE This study aims to determine the occurrence of complications before and after the treatment of facial fractures, as well as the impact of the factors on the treatment results and evaluation of their relationships. PATIENTS AND METHODS This is a prospective case-control study comprising 90 patients aged between 18 and 65 with facial fractures. Depending on the treatment method, patients were divided into three groups: those treated surgically using a transcutaneous approach, those treated surgically using a transmucosal approach, and those treated conservatively (control group). Following complications before and after treatment were compared: malocclusions, paresthesias, facial asymmetry, diplopia, and limited mouth opening. The follow-up period after the treatment of choice was six months. RESULTS There was a significant reduction in complications after treatment: malocclusion, paresthesia, facial asymmetry, and limited mouth opening. Regarding the transcutaneous approach, there is a substantial reduction in the number of complications after treatment, such as malocclusions (p=0.008), paresthesias (p=0.004), and facial asymmetries (p<0.001). Similar results were obtained for the transmucosal approach. Pain intensity positively correlated with preoperative complications: malocclusion, paresthesias, and facial asymmetry. The range of mouth opening had a negative interdependence with malocclusion before and after treatment with infection, fractura male sanata, malocclusion, paresthesias, postoperative level of mouth opening, and damage to the facial nerve. CONCLUSIONS There is no difference in the reduction of preoperative and postoperative complications related to surgery when an incision is made through the skin or mucosa. Malocclusions, paresthesias, and facial asymmetry are reduced through surgical methods.

Abstract
This study aimed to compare open and closed treatment for unilateral mandibular condyle neck and base fractures by final three-dimensional (3D) condylar position at 6 months follow-up. 3D position was associated with mandibular functioning and pain. A total of 21 patients received open (n = 11) or closed (n = 10) treatment. 3D positions were assessed on cone-beam computed tomography scans. Volume differences, root mean square, translations, and rotations were obtained related to the pursued anatomical position and compared between treatment groups by the Mann-Whitney U test. The 3D position parameters were associated with the maximum interincisal opening (MIO), mixing ability test (MAT), Mandibular Function Impairment Questionnaire (MFIQ), and pain based on Spearman correlation coefficients (rs). Translation in the medial-lateral direction was smaller after open treatment (P = 0.014). 3D position was not associated with the MAT; however, worse position was associated with a smaller MIO. A larger pitch rotation was associated with a worse MFIQ (rs = 0.499, P = 0.025). Volume reduction of the affected condyle was associated with more pain (rs = -0.503, P = 0.020). In conclusion, after unilateral condylar fractures, worse 3D position is associated with a smaller mouth opening and worse patient-reported outcomes. This is independent of the chosen treatment, despite a better anatomical reduction after open treatment.

Abstract
OBJECTIVE Surgical innovation led to an endoscopic-assisted intraoral approach for managing condyle fractures. The purpose of this systematic review is to purview the role of the endoscope and determine the range of information, summarizing the evidence for the benefit of surgeons on an endoscopic-assisted intraoral approach. STUDY DESIGN A literature search was conducted in PubMed, Google Scholar, Semantic Scholar, and Cochrane Library databases for studies mentioning the endoscopic intraoral approach for managing mandibular condylar fractures. Outcomes include the role of the endoscope, challenges, adjunct armamentarium, duration, and complications associated with the transoral and transbuccal approach for screw fixation. The meta-analysis was conducted with prevalence estimates and standardized means using STATA. RESULTS Thirty-nine studies were included. A 30° angulated, 4-mm-thick endoscope was the most commonly used endoscope. Two mini plates were most commonly used for fixation. Facial nerve weakness was higher in the transbuccal approach (1.24%) than in the transoral approach (0.8%). Pooled analysis (6 studies) showed that the duration of the surgical procedure was less in the transoral approach compared with the transbuccal approach for screw fixation. The bailout was 1.49%. CONCLUSIONS The endoscopic-assisted intraoral approach is reliable for condylar fracture management. The transoral and transbuccal approaches can be used for screw fixation with comparable outcomes.

Abstract
BACKGROUND Bisphosphonates inhibit bone resorption in patients with postmenopausal osteoporosis and reduce osteoporotic fracture incidence. Medication-related osteonecrosis of the jaws (MRONJ) and atypical femoral fractures (AFF) are both rare but serious adverse effects of anti-resorptive drugs (ARD) such as bisphosphonates. The most advanced form of MRONJ is termed stage 3 and can lead to severe local sequelae like pathologic mandibular fractures (PMF). This study reports a case of MRONJ-related PMF and AFF with osteomyelitis secondary to bisphosphonate treatment for osteoporosis. CASE REPORT A 63-year-old white woman was diagnosed with PMF related to MRONJ stage 3 during treatment of an AFF with osteomyelitis. She had been treated for postmenopausal osteoporosis with 70 mg of alendronate weekly for 2 years. The PMF was treated by stable internal fixation combined with debridement and sequestrectomy, but further debridement was required and 2 mandibular implants were then removed. Postoperative recovery was uneventful and the mandibular infection was controlled after the second surgery. Three weeks later, she was discharged from the hospital, instructed to discontinue the use of alendronate, and referred for 30 sessions of hyperbaric oxygen therapy. At the 3-year follow-up, the PMF was completely healed without signs of mandibular infection or bone exposure. CONCLUSIONS This report raises awareness of both MRONJ and AFF as possible adverse effects of short-term bisphosphonate therapy for postmenopausal osteoporosis, and highlights the importance of dental and orthopedic follow-ups. It is crucial to emphasize the need for early diagnosis and treatment to prevent MRONJ progression to PMF.

Abstract
AIM The aim of this study was to evaluate a clinically and radiographically Z-shaped miniplate for the fixation of the parasymphyseal fractures. PATIENTS AND METHODS Twenty patients (10 patients in each group) who had parasymphseal mandibular fractures were randomly selected for this study. In this study, open reduction and internal fixation were performed for mandibular parasymphyseal region fractures using two miniplates as group I, and open reduction and internal fixation were performed for mandibular parasymphyseal region fractures using a newly designed Z-shaped miniplate as group II. Clinical and radiographic evaluations were made. Each patient was evaluated: (1) clinically evaluated preoperatively and postoperatively for operating time, ease of placement of the miniplate, and occlusion and (2) radiological: postoperative reduction of fracture was evaluated radiologically at 5-day, 1-month, 2-month, and 3-month intervals with orthopantomogram, and lingual splaying was evaluated by cone-beam computed tomography (CBCT) immediately postoperatively and at an interval of 3 months. The collected data were subjected to statistical analysis. Data analysis was performed by SPSS software, version 25 (SPSS Inc., PASW statistics for Windows version 25). Chicago: SPSS Inc. RESULTS There was a statistically significant difference (p < 0.001) between the mean intraoperative time. This indicates that group I had a longer time for fracture fixation than group II. Group I had a longer time elapsed for plate adaptation and definitive fixation than group II. Occlusion and reduction stability in both groups were similar. There was a statistically significant difference in postoperative lingual display control after 5 days and 3 months between the studied groups. This indicates that lingual display control in group II is better than in group I. CONCLUSION The Z-shaped miniplate is effective and provides three-dimensional stability for the fixation of parasymphyseal fractures, ease of use, easily adapted in cases of fractures near the mental nerve reduced operative time, and better control of lingual splaying than conventional miniplates. CLINICAL SIGNIFICANCE The newly designed Z-shaped miniplate is a valuable option for fixation parasymphysis fractures that need open reduction and internal fixation instead of using conventional miniplates, which are less successful in controlling lingual splaying.

Abstract
BACKGROUND Cannabis is the third most used controlled substance in the world. Despite its widespread use, minimal research investigates cannabis usage in patients undergoing facial fracture surgeries. This study aimed to evaluate patterns of postoperative complications related to cannabis and tobacco usage after mandible fracture surgeries. MATERIALS AND METHODS PearlDiver™, a commercially available healthcare database, was used to identify patients endorsing the use of cannabis, tobacco, or both who underwent mandible fracture surgeries for cross-sectional analysis. The study population was categorized into groups using the Classification of Diseases, 9th revision (ICD-9), ICD-10, and Current Procedural Terminology (CPT) codes. A chi-square analysis was performed to assess the influence of cannabis and tobacco use on postoperative complications. RESULTS A total of 8288 patients met the inclusion criteria, with 72 patients with cannabis-only usage, 914 patients with cannabis and tobacco usage, 3236 patients with tobacco-only usage, and 4066 in the control group. For patients using only cannabis, there was not an increased risk of developing postoperative complications compared with the control population. Patients with concurrent cannabis and tobacco usage and those with tobacco-only usage had an increased risk of surgical site infection, facial nonunion, facial abscess, debridement, and malocclusion after surgical repair of mandibular facial fracture. CONCLUSION Patients with tobacco-only as well as cannabis and tobacco usage had an increased risk of all postoperative complications, except malocclusion, compared with cannabis-only. Based on the results of this study, it is recommended that healthcare providers consider a patient's history of tobacco use when planning and performing surgical treatment for traumatic mandible fractures.

Abstract
OBJECTIVES Since the introduction of miniplate osteosynthesis and the use of prophylactic antibiotics, the complication rate related to the teeth in the fracture gap has significantly decreased. Currently, there are still no established guidelines for the management of such teeth in mandibular fracture lines. However, the long-term viability of these teeth within the fracture gap remains uncertain. Therefore, this study aimed to assess the survival rate of teeth located within the mandibular fracture line and evaluate related follow-up treatments over a minimum period of one year. MATERIALS AND METHODS This retrospective study examined 184 patients who underwent surgical treatment for mandibular fractures between January 2018 and December 2021. A total of 189 teeth located in the fracture line were analyzed. Clinical and radiological parameters were collected, including patient age and gender, fracture etiology and location, intraoperative tooth treatment, as well as complications related to both the fracture and the affected teeth in long term. RESULTS Most of the examined teeth remained uneventful, with postoperative tooth-related complications seen in 14 (7.4%) teeth. The most common complications were symptomatic apical periodontitis (n = 9, 4.8%) and increased tooth mobility (n = 3, 1.5%). A correlation was found between complications and trauma-related tooth luxation (p = 0.002, OR = 15.2), as well as prior teeth connected to retainers or orthodontic appliances (p = 0.001, OR = 10.32). CONCLUSION Tooth-related complications are rare when intact teeth are retained within the fracture gap. Therefore, unless there is a definitive intraoperative indication for extraction, it is recommended to preserve the teeth in the fracture line. CLINICAL RELEVANCE Intact teeth in the fracture line of the mandible should not be primarily extracted.

Abstract
The study group patients have been treated with 1.6 microplates at the superior border and 2.0 miniplate at the inferior border to evaluate its efficacy in the fixation of symphyseal and parasymphyseal fractures using this technique. The control patients were treated with two 2.0 plates. The stability was assessed using computed tomography immediately performed postoperatively and after 6 months. Assessment of the change in the intercanine distance using the Student T test was statistically Non Significant ( P value 0.34). The change of intercanine distance in the study was 0.04 ± 0.05 mm, compared with that of the control, which was 0.01 ± 0.03 mm. Assessment of change in intermental foramina distance was statistically NS ( P value = 0.06). The average difference in intermental foramina distance in the study was 0.04 ± 0.05 mm, compared with the control, which was 0.002 ± 0.004 mm. Based on the findings of the current study, the authors recommend the use of microplates combined with miniplates in the correction of both symphyseal and parasymphyseal fractures successfully.

Abstract
PURPOSE Using network meta-analyses (NMA) has become increasingly valuable as it enables the comparison of interventions that have not been directly compared in a clinical trial. To date, there has not been a NMA of randomized clinical trials (RCT) that compares all types of treatments for mandibular condylar process fractures (MCPFs). The aim of this NMA was to compare and rank all the available methods used in the treatment of MCPFs. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic search was conducted in 3 major databases up to January 2023 to retrieve RCTs that compared various closed and open treatment methods for MCPFs. The predictor variable is treatment techniques: arch bars (ABs) + wire maxillomandibular fixation (MMF), rigid MMF with intermaxillary fixation screws, AB + functional therapy with elastic guidance (AB functional treatment), AB rigid MMF/functional treatment, single miniplate, double miniplate, lambda miniplate, rhomboid plate, and trapezoidal miniplate. Postoperative complications were the outcome variables and included occlusion, mobility, and pain, among other things. Risk ratio (RR) and standardized mean difference were calculated. Version 2 of the Cochrane risk-of-bias tool and Grading of Recommendations, Assessment, Development, and Evaluations system were used to determine the certainty of the results. RESULTS The NMA included a total of 10,259 patients from 29 RCTs. At ≤6 months, the NMA revealed that the use of 2-miniplates significantly reduced malocclusion compared to rigid MMF (RR = 2.93; confidence interval [CI]: 1.79 to 4.81; very low quality) and functional treatment (RR = 2.36; CI: 1.07 to 5.23; low quality).Further, at ≥6 months, 2-miniplates resulted in significantly lower malocclusion compared to rigid MMF with functional treatment (RR = 3.67; CI: 1.93 to 6.99; very low quality).Trapezoidal plate and AB functional treatment were ranked as the best options in 3-dimensional (3D) plates and closed groups, respectively.3D-miniplates (very low-quality evidence) were ranked as the most effective treatment for reducing postoperative malocclusion and improving mandibular functions after MCPFs, followed closely by double miniplates (moderate quality evidence). CONCLUSIONS This NMA found no substantial difference in functional outcomes between using 2-miniplates versus 3D-miniplates to treat MCPFs (low evidence).However, 2-miniplates led to better outcomes than closed treatment (moderate evidence).Additionally, 3D-miniplates produced better outcomes for lateral excursions, protrusive movements, and occlusion than closed treatment at ≤6 months (very low evidence).

Abstract
OBJECTIVE To describe a treatment for a mandibular fracture in a guinea pig (Cavia porcellus). ANIMAL A 6-month-old sexually intact male guinea pig referred for a 24-hour history of hyporexia. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES Physical examination showed lateral displacement of the incisors and inflammation and crepitation during mandible lateralization. Imaging tests revealed a minimally displaced complete oblique fracture of the left mandible with fracture of the left mandibular first premolar tooth and incisor tooth. TREATMENT AND OUTCOME Conservative treatment was established by placing a chin sling (CS) to immobilize the jaw and a nasogastric tube for nutritional support. Imaging tests repeated 3 weeks later showed initial callus formation, and the conservative treatment was discontinued. Follow-up examinations showed appetite and progressive weight gain. Five months later, the clinical crown of the left mandibular incisor was absent and a resorptive lesion on the left mandibular first premolar tooth was detected. Complete ossification of the fracture without premolar and moler teeth elongation was observed on control imaging tests. Ten months after initial examination, the patient was reportedly healthy with no signs of pain or dental disease. CLINICAL RELEVANCE Jaw fracture treatments in guinea pigs are poorly described in the literature. Surgical treatment can be challenging in this species due to its skull and dental anatomy. Although CS was originally employed to increase the congruency of premolar and molar teeth after coronal reduction, this device yielded satisfactory results as a noninvasive, inexpensive treatment of a mandibular fracture in this guinea pig. Alopecia on the back of the head was the only undesired adverse effect associated with the CS.

Abstract
Mandible subcondylar fractures have very high complication rate, yet there is no consensus on suitable plate design for optimal patient outcomes. Our study is aimed at comparing single mini, trapezoid, lambda, strut and double mini plates. A finite-element (FE) model of intact mandible was developed based on healthy CT-scan data, which was further virtually osteotomized and fixated with plates. The cortical and cancellous bones were assigned region-specific orthotropic and heterogenous isotropic material properties respectively. The models were subjected to six load cases representing the mastication cycle. Under opposite lateralities, the tensile and compressive mandibular strain distributions were found as the opposite, with tensile strains at the posterior border under ipsilateral molar clenching (RMOL) resulting in lesser mandibular strain in reconstructed mandible with single mini plate under RMOL but highest mandibular strain under the contralateral molar clenching (LMOL). Owing to the reduced mandibular strains under LMOL than RMOL, the contralateral chewing is preferred during the immediate post-surgery period for patients. Under LMOL, the peak von Mises stresses in the plate decreased with increase in the number of screws. Furthermore, the presence of two arms in double mini and trapezoid plates seems beneficial to neutralise the tensile and compressive strains across load cases.

Abstract
BACKGROUND/AIM Different types of plates are used in clinical practice for the management of subcondylar fractures. This study aimed to compare the performance of poly- L -lactic acid (PLLA) and titanium trapezoidal plates in the fixation of subcondylar mandibular fractures using finite element analysis. METHODS Titanium and PLLA trapezoidal plates and screws were placed on the virtual model obtained from computed tomography images of a patient with a subcondylar fracture to perform finite element analysis. The analysis included maximum tension distribution, maximum principal strain, displacement, and deformation of the bone, plates, and screws. RESULTS The maximum tension distribution and maximum principal stress were found to be significantly higher on the titanium plate than on the PLLA plate and screws. Almost no difference was found between the trapezoidal and PLLA plates regarding the displacement of the fracture fragments at the fracture line. No difference was recorded regarding the displacement of the PLLA and titanium screws. The values of maximal principal strain between the PLLA and titanium materials showed no significant difference. CONCLUSIONS The trapezoidal PLLA plates can be an alternative to trapezoidal titanium plates due to their functional stability and rigidity.

Abstract
This paper aims to present a rare case report of bilateral pseudoaneurysm secondary to condylar fracture and its management with a brief review of literature. A patient of age 19 years with alleged history of road traffic accident presented 6 weeks lately to our department with slow growing swelling in right preauricular area. History revealed bilateral condylar fracture with right parasymphysis fracture of mandible for which patient underwent maxillomandibular fixation for 4 weeks. The diffuse swelling in preauricular region showed positive signs of pulsation and audible bruit. Ultrasonography and contrast-enhanced computed tomography suggested the bilateral presence of vascular anamoly from the terminal branches of external carotid artery. Diagnostic angiography confirmed presence of pseudoaneurysm at the bifurcation of the internal maxillary artery and superficial temporal artery (STA) on right side whereas on the left side it was at proximal STA. Bilateral endovascular coil and gel foam embolization was done and thrombosis was confirmed with high frequency ultrasound on fourth postintervention day. The swelling completely resolved in a period of 1 month with no evidence of recurrence in the following 2-year follow-up period. Routine investigation revealed presence of pseudoaneurysm on left side which was completely without any clinical signs as repoterd by many cases of condylar fracture in the literature review. Pseudoaneurysm may remain silent and are exposed intraoperatively with massive bleeding which causes significant morbidity. Hence, prompt diagnosis and management is essential to avoid unexpected complication perioperatively.

Abstract
BACKGROUND The fracture of mandibular symphysis combined with bilateral condylar fractures often leads to changes in the width of the mandible, which significantly widens the face of the child. Therefore, it is necessary to reposition the mandible through accurate adduction. METHODS To ensure that the mandible can be accurately repositioned, a 3D printed occlusal splint was used. Bilateral maxillomandibular fixation screws were implanted. The 3D printed occlusal splint was located on the maxillary dentition and fixed to the maxillomandibular fixation screws with wire loops. The reference basis for adduction is to make the mandibular dentition located in the occlusal splint. The absorbable plate was contoured according to the restored model and fixed at the fracture site. The 3D printed occlusal splint was retained in the maxillary dentition for two months. RESULTS AND DISCUSSION Postoperative computed tomography showed that the mandible had been adducted according to the preoperative design. Two months of follow-up showed that the child's facial development, mouth opening type, occlusion, and range of motion were good. It is especially suitable for children with mandibular symphyseal fractures accompanied by bilateral condylar fractures.

Abstract
Only a few mandibular bone finite element (FE) models have been validated in literature, making it difficult to assess the credibility of the models. In a comparative study between FE models and biomechanical experiments using a synthetic polyamide 12 (PA12) mandible model, we investigate how material properties and boundary conditions affect the FE model's accuracy using the design of experiments approach. Multiple FE parameters, such as contact definitions and the materials' elastic and plastic deformation characteristics, were systematically analyzed for an intact mandibular model and transferred to the fracture fixation model. In a second step, the contact definitions for the titanium screw and implant (S-I), implant and PA12 mandible (I-M), and interfragmentary (IF) PA12 segments were optimized. Comparing simulated deformations (from 0 to -5 mm) and reaction forces (from 10 to 1'415 N) with experimental results showed a strong sensitivity to FE mechanical properties and contact definitions. The results suggest that using the bonded definition for the screw-implant contact of the fracture plate is ineffective. The contact friction parameter set with the highest agreement was identified: titanium screw and implant μ = 0.2, implant and PA12 mandible μ = 0.2, interfragmentary PA12 mandible μ = 0.1. The simulated reaction force (RMSE = 26.60 N) and surface displacement data (RMSE = 0.19 mm) of the FE analysis showed a strong agreement with the experimental biomechanical data. The results were generated through parameter optimization which means that our findings need to be validated in the event of a new dataset with deviating anatomy. Conclusively, the predictive capability of the FE model can be improved by FE model calibration through experimental testing. Validated preoperative quasi-static FE analysis could allow engineers and surgeons to accurately estimate how the implant's choice and placement suit the patient's biomechanical needs.

Abstract
Reconstruction of facial trauma has seen a significant evolutionary leap in the last 100 years. The current surgical management of facial fractures was made possible by the efforts and creativity of pioneer surgeons, advances in anatomic understanding, and the continued development of biomaterials and imaging technologies. Virtual surgical planning (VSP) and 3-dimensional printing (3DP) are being incorporated into the management of acute facial trauma. The integration of this technology at the point of care is rapidly expanding globally. This article reviews the history of the management of craniomaxillofacial trauma, current practices, and future directions. The use of VSP and 3DP in facial trauma care is highlighted with a description of EPPOCRATIS, a rapid point-of-care process incorporating VSP and 3DP at the trauma center.

Abstract
The aim of this study was to assess whether the resorption of poly-lactic acid pins, used for condylar head fracture fixation, adversely affect remodelling of the condylar head. A retrospective review of patients was performed that underwent ORIF of CHF with ultrasound activated resorbable poly-lactic acid pins and had CT/CBCT scans of the condyle at least 18 months after surgery, at which point the fixation material was expected to be resorbed. We reviewed the size, shape and position of the condylar head and compared this to the normal side and compared this to the results of conservative management and ORIF with titanium screws in the literature. Most patients had condylar heads normally positioned and shaped, with minimal bone changes. The position of the condyle in the fossa, its shape and bone changes compare favourably with previous studies on CHF managed conservatively or with titanium screw fixation. There was no radiographic evidence of the pins after 18 months. In conclusion, ultrasound activated resorbable pins can provide suitable fixation for ORIF of condylar head fractures, avoiding the need for screw removal, and there was no evidence that the resorption process adversely affected the remodelling of the condylar head.

Abstract
AIM The present study was designed to investigate the difference in the effectiveness of a 3 day postoperative course and a single perioperative dose of antibiotics on the incidence of postoperative infection in the management of maxillofacial trauma patients. MATERIALS AND METHODS About 183 maxillofacial trauma patients requiring open reduction and internal fixation (ORIF) under general anesthesia were divided based on the type of fracture sustained, i.e., mandibular fractures, Le Fort fractures, and zygomaticomaxillary complex fractures. Patients from each fracture type were randomized into two groups, A and B. All patients were administered amoxicillin/clavulanate 1.2 grams intravenously 8 hours from the time of admission till the patient was taken up for surgery. Once the patients were taken up for surgery, a perioperative dose was administered. No antibiotics beyond this point were given to patients in Group A. Patients in Group B were administered the same antibiotic for 3 postoperative days additionally. Outcomes in terms of purulent discharge from the surgical site, an abscess or any other sign of infection, and wound dehiscence requiring reopening of the surgical site were considered. Patients were reviewed at 1 week, 2 weeks, 1 month, 2 months, and 3 months. RESULTS No statistically significant difference was found between the two groups across all three fracture types in terms of postoperative outcomes. However, increased numbers of complications were noted in the patients treated with an intra-oral approach in each fracture type irrespective of group. All complications were managed with local measures. CONCLUSION A single perioperative dose of antibiotics is effective in minimizing postoperative complications following ORIF of maxillofacial fractures and there is no significant benefit in prolonging the course of antibiotics postoperatively with the need for further studies to be conducted considering comminuted, complex fractures and old fractures. CLINICAL SIGNIFICANCE In maxillofacial trauma, fractures frequently communicate with contaminated indigenous flora on the skin surface, oral cavities, or sinus cavities. Surgery is frequently performed using an approach across a contaminated area, even in closed fractures. Postoperative infections can be significantly decreased by using antibiotics in surgical procedures to treat facial fractures.

Abstract
BACKGROUND Compared with other facial fractures, mandibular fractures have the highest rate of postsurgical site infection. There is strong evidence to suggest that postoperative antibiotics do not reduce rates of surgical site infections (SSIs) regardless of duration. However, there are conflicting data in the literature regarding the role of prophylactic preoperative antibiotics in reducing rates of SSIs. This study reviews the rate of infections in patients who underwent mandibular fracture repair who received a course of preoperative prophylactic antibiotics compared with those who received no or 1 dose of perioperative antibiotics. METHODS Adult patients who underwent mandibular fracture repair at Prisma Health Richland between 2014 and 2019 were included in the study. A retrospective cohort review was conducted to determine the rate of SSI, comparing 2 groups of patients who underwent mandibular fracture repair. Patients who received more than 1 dose of scheduled antibiotics before surgery were compared with those who did not receive any antibiotic treatment before surgery or received only a single dose of antibiotics within 1 hour of incision time (perioperative antibiotics). The primary outcome was the rate of SSI between the 2 groups of patients. RESULTS There were 183 patients who received more than 1 dose of scheduled antibiotics before surgery and 35 patients who received a single dose of perioperative antibiotics or did not receive any antibiotics. The rate of SSI was not significantly different in the preoperative prophylactic antibiotics group (29.3%) compared with the patients who received a single perioperative dose or no antibiotics (25.0%). CONCLUSION Extended regimens of preoperative prophylactic antibiotics beyond a single dose at time of surgery do not reduce SSIs after surgical repair in mandibular fractures.

Abstract
Mandibular fractures are rare in children and normally result from high-impact trauma. Clinical protocols have evolved in recent years, especially after the introduction of rigid internal fixation methods and the development of novel resorbable materials. The purpose of this report is to present the case of a three-year-old toddler who fell from a bunk bed at home, resulting in a unilateral fracture of the mandibular parasymphysis and a joint fracture on the left side. The patient was treated under general anesthesia with rigid internal fixation with biodegradable plates and screws. Pediatric patients can benefit from resorbable materials, especially their faster mobilization and avoidance of secondary removal operations. Self-reinforced fixation devices are safe and efficient for the treatment of pediatric mandible fractures. However, further clinical investigations are needed to evaluate long-term reliability.

Abstract
The midface skeleton provides structural scaffolding to the middle third of the face. Complications associated with fracture repair in these regions can result from incomplete, inaccurate, or delayed assessment, poor initial and subsequent reduction and fixation, infection, uncontrolled hemorrhage, hardware failure and associated soft tissue injuries. A systematic approach to managing the patient with facial trauma that includes Acute Trauma Life Support principles, early reconstruction, and precise reduction and fixation is essential to reducing the short-term and long-term risks of complications.

Abstract
The aim of this study is to devise and summarize a classification of fracture patterns involving multiple anatomical sites of the mandible. A retrospective study was conducted by reviewing clinical case records, imaging records, and the surgical management of patients presenting with mandibular fracture. Demographic data were collected and causes of the fractures were studied. Following radiological evaluations based on the courses of fracture lines, these fractures were categorized into three components: horizontal (H), vertical (V), and sagittal (S). In case of horizontal components, the mandibular canal was used as a reference. For vertical components, the fracture lines were classified according to where they terminated. With sagittal components, the direction of the bicortical split at the base of mandible was used as a reference. Out of a total of 893 mandibular trauma patients, 30 unusual fractures were identified (21 in males and nine in females), which do not fit into existing classifications. These were mainly due to road traffic accidents. Horizontal components of fractures were classified as H-I, H-II, and H-III, and vertical components as V-I, V-II, and V-III. For sagittal components, two types were identified - S-I and S-II - resulting in a bicortical split of the mandible. This classification is proposed to help understanding the complex fractures and to allow standardized communication among clinicians. Moreover, it is designed in such a way that aids in the choice of fixation technique. Further studies are needed to establish standardized treatment algorithms for efficient management of these unusual fractures.
