Abstract
Background: We experienced a case of malunion of condylar fracture after miniplate fixation in a patient with a 40 pack-year smoking history who restarted smoking at 5 weeks postoperatively. Case: A 64-year-old man lost consciousness and fell down, hitting his chin on the floor. He had malocclusion and open bite bilaterally. The mouth opening was 1.5-finger breadths. He had a 40 pack-year smoking history. Radiology revealed a bilateral condylar fracture and a fracture of the parasymphysis. Intermaxillary fixation was done using the skeletal anchorage system on the first post-trauma day. On the third post-trauma day, vertical ramus osteotomy, miniplate fixation of the fractured condylar neck, and free grafting were performed. When the wire was changed to a rubber band at 5 weeks postoperatively, he started smoking (half-pack a day). At 7 weeks postoperatively, the skeletal anchorage system was removed and some absorption of the condylar head was observed. At 3 months postoperatively, his mouth opening was 24 mm and no malocclusion was present, although the condylar head was distorted and malunion was observed. At 4 months postoperatively, his mouth opening was 30 mm but he complained of pain on do so. Distortion of the condylar head was aggravated. At 5 months postoperatively, his pain continued but was endurable. He continued smoking (half-pack a day) since 5 weeks postoperatively. Conclusion: In smokers, a longer period of immobilization is needed in bone grafting of the fractured condylar head. Longer immobilization provides sufficient time for healing and prevents smoking, since the patient cannot smoke easily when the intermaxillary fixation is applied.

Complications after different methods for fixation of mandibular angle fractures: network meta-analysis of randomized controlled trials. Int J Oral Maxillofac Surg 2021; 50:1450-1463. [PMID: 33676800 DOI: 10.1016/j.ijom.2021.02.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 12/14/2020] [Accepted: 02/04/2021] [Indexed: 10/22/2022]
Abstract
The aim of this review was to compare mandibular angle fracture fixation methods that were evaluated through randomized clinical trials considering postoperative complications. Additionally, different treatment methods were ranked based on their performance. A systematic review was performed based on the Cochrane and PRISMA guidelines. The quality of evidence and network meta-analysis were conducted using the GRADE tool and R software, respectively. Four databases were searched, and the papers were selected based on the PICOS strategy. A total of 3584 papers were found. After screening 15 papers were included. One plate placed on lateral border (tension zone) presented lower risk than one plate placed on superior border (tension zone) for infection [risk ratio (RR): 0.48, 95% confidence interval (CI): 0.33 to 0.71] and plate removal necessity (RR: 0.44, 95% CI: 0.28 to 0.69), with moderate quality of evidence. There were no significant differences among the mandibular angle fracture treatments for malocclusion and paraesthesia outcomes. In conclusion, one plate placed on the lateral border in the tension zone is the best choice regarding postoperative infection and plate removal necessity when fixing mandibular angle fractures. None of the tested fixation methods were associated with a significant risk of malocclusion and paraesthesia events.

Lee WB, Kim YD, Shin SH, Lee JY. Prognosis of teeth in mandibular fracture lines. Dent Traumatol 2021; 37:430-435. [PMID: 33421357 DOI: 10.1111/edt.12647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 12/08/2020] [Accepted: 12/08/2020] [Indexed: 11/27/2022]
Abstract
BACKGROUND/AIMS Teeth in a jaw fracture line, because of the presence of the periodontal ligament, may communicate with the oral cavity. There are no guidelines for the management of teeth in mandibular fracture lines. The aim of this study was to investigate the factors related to dental problems with teeth involved in mandibular fracture lines and to determine the best treatment option. MATERIAL AND METHODS This retrospective study was based on the medical and radiographic records of patients with mandibular fractures. The relationships among the patient's age, gender, smoking history, amount of bony displacement, surgery, trauma-surgery period, apical involvement, tooth mobility, and periodontal status were investigated. Group comparisons were performed using the chi-squared test, Fisher's exact test, and Mann-Whitney U-test. RESULT A total of 238 patients (247 fracture lines) with mandibular fractures including a tooth in the line of the fracture were examined. Post-operative dental complications occurred in 42 cases (17.0%). Extraction of related teeth occurred in 34 cases (80.9%) compared to eight cases (19.0%) related to root canal therapy. This study defined "dental problem" as "a case with a tooth extracted or endodontically treated after trauma." The variables associated with an increased risk of dental problems were the amount of bony displacement (p < .01), tooth mobility (p < .01), and pre-existing marginal alveolar bone loss (p = .027). CONCLUSION The prognosis of teeth in mandibular fracture lines was related to tooth mobility, periodontal state, and the amount of bony displacement.

Abstract
Background/objectives Gunshot injuries are known to cause severe morbidity and mortality when facial regions are involved. Management of the gunshot wounds of the face comprises of securing an airway, controlling hemorrhage, identifying other injuries and definite repair of the traumatic facial deformities. The objective of the present study was to compare the clinical outcome (infection and nonunion) of open reduction and internal fixation versus closed reduction and maxillo-mandibular fixation (CR-MMF) in the treatment of gunshot injuries of the mandible. Materials & methods This study was conducted at Oral and Maxillofacial Surgery Department of Shaheed Zulfiqar Ali Bhutto Medical University/Pakistan Institute of Medical Sciences Islamabad, Pakistan. Ninety gunshot mandibular fractures were randomly allocated in two equal groups. In group-A, 45 patients were treated by open reduction and internal fixation while in group-B, 45 patients were also managed by closed reduction and maxillo-mandibular fixation. Post-operative complications (infection, non-union) were evaluated clinically and radiographically in both groups. Results Patients treated by open reduction and internal fixation were having more complications in terms of infection (17.8%) as compared to closed reduction (4.4%) with a p-value 0.044. Whereas non-union was more in closed reduction (15.6%) as compared to open reduction and internal fixation group (2.2%) with a significant p-value 0.026. Conclusion Both the treatment modalities can be used in the management of gunshot injuries of mandible and there is need for further studies to have clear guideline in this regard in best interest of patients, community and health care providers.

Abstract
Closed reduction and maxillomandibular fixation (MMF) is associated with airway obstruction. The ventilatory effect of open reduction and rigid internal fixation (ORIF) as an alternative treatment has not been determined. The aim of this study was to compare the effects of MMF and ORIF on pulmonary function (PF) in patients with mandibular fractures. Using a computer-generated simple randomization protocol, 40 eligible participants were allocated to MMF and ORIF treatment groups. PF tests were done preoperatively and at 24hours, 1, 6, and 7 weeks postoperative in all participants in both groups, using a portable office spirometer (Spirobank G). Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, and peak expiratory flow rate (PEFR) were determined. At 6 weeks postoperative, PF tests were performed after the release of MMF. PF tests in the MMF and ORIF groups were similar preoperatively. At 24hours postoperative, FEV1/FVC was significantly lower in the MMF group than in the ORIF group (p<0.001). Values of FEV1 (p=0.022), FEV1/FVC (p=0.001) and PEFR (p<0.001) were significantly lower in the MMF group than in the ORIF group at 1 week postoperative. While MMF negatively impacted on PF, ORIF had no adverse effect on PF.

Abstract
Aims The purpose of this article was to study and devise a classification of fracture patterns of the mandibular ramus to facilitate management. Methods Mandibular ramus fracture demographics in literature were reviewed along with evaluation of the patients diagnosed with mandibular ramus fractures who had reported to the emergency/outpatient clinic of our Institute in the last 5 years. Epidemiology of these ramus fractures was studied, and these ramus fractures were categorized into repetitive patterns on the basis of radiological observations in an effort to achieve a simplified classification. Results A total of 1372 trauma patients were diagnosed with mandibular fractures, of which an incidence of 2.4% was recorded for ramus fractures. These were predominantly in males and mainly due to road traffic accidents commonly in people driving two-wheeler vehicles (64%). Ramus fractures seldom occur in isolation. Five predictable fracture patterns were observed and accordingly classified as types I to V. Type I was the most common and type IV the least. Open reduction was done in 45.5% patients with non-compression plating systems. Satisfactory aesthetic and functional outcomes were achieved in all patients. Conclusion The mandibular ramus fractures although rare need to be well understood and demarcated. The classification highlights the importance of this mandibular buttress and focuses on the importance of its technically and anatomically more complicated fracture treatment. Future studies are needed to compare the modalities of management.

Abstract
Traumas are a major problem worldwide. A considerable proportion of traumas are located in the cephalic extremity. Neglect of these disorders by patients or those responsible for patient management may result in particularly serious consequences. This paper presents the case of a 58-year-old male patient with an intraorally open mandibular fracture, which left untreated for 3 days, was complicated by Ludwig's angina. Following aggressive surgical treatment during which the mandibular fracture was manually reduced and immobilized with a metal splint fixed with circumdental wires and effective antibiotic therapy, the septic process was terminated and the patient's fracture and infected wound were healed. The correct and rapid treatment of open mandibular fractures is mandatory in order to avoid severe septic complications.

Abstract
Background Mandible is one of the most prominent bones of the facial skeleton leading to high prevalence of fracture during facial trauma. The management of mandibular fractures has evolved from intermaxillary fixation (IMF) to a combination of IMF and wire osteosynthesis, lag screw, and plate fixation. Despite the evolution in techniques, no technique including open reduction and internal fixation (ORIF) has proven to be completely devoid of complications. However, ORIF has many advantages and has resulted in better outcome when compared with the closed reduction methods. Aim The aim of this retrospective study is to assess the incidence of postoperative complications in 98 patients treated with ORIF for mandibular fractures. Materials and Methods A sample size of 98 patients with mandibular fractures reporting to Saveetha Dental College and Hospital, Chennai, from January 2014 to November 2016, treated by ORIF was included in the study and was split into three groups. The patient's records were analyzed for deriving the number and type of complications that occurred during the postoperative period of ORIF. Results Patients with fractures in the condyle region reported with the highest number of complications when compared to the angle and parasymphysis regions. The most common complications that the patients reported were infection that led to plate removal and paresthesia. Others were wound dehiscence, occlusal disturbances, and facial nerve paralysis which were less common. Conclusion The most common postoperative complication of the procedure in this retrospective study was found to be infection of the plates that are preventable with better aseptic techniques.

Abstract
The AO CMF has recently launched the first comprehensive classification system for craniomaxillofacial (CMF) fractures. The AO CMF classification system uses a hierarchical framework with three levels of growing complexity (levels 1, 2, and 3). Level 1 of the system identifies the presence of fractures in four anatomic areas (mandible, midface, skull base, and cranial vault). Level 2 variables describe the location of the fractures within those defined areas. Level 3 variables describe details of fracture morphology such as fragmentation, displacement, and dislocation. This multiplanar radiographic image-based AO CMF trauma classification system is constantly evolving and beginning to enter worldwide application. A validation of the system is mandatory prior to a reliable communication and data processing in clinical and research environments. This interobserver reliability and accuracy study is aiming to validate the three current modules of the AO CMF classification system for mandible trauma in adults. To assess the performance of the system at the different precision levels, it focuses on the fracture location within the mandibular regions and condylar process subregions as core components giving only secondary attention to morphologic variables. A total of 15 subjects individually assigned the location and features of mandibular fractures in 200 CT scans using the AO CMF classification system. The results of these ratings were then statistically evaluated for interobserver reliability by Fleiss' kappa and accuracy by percentage agreement with an experienced reference assessor. The scores were used to determine if the variables of levels 2 and 3 were appropriate tools for valid classification. Interobserver reliability and accuracy were compared by hierarchy of variables (level 2 vs. level 3), by anatomical region and subregion, and by assessor experience level using Kruskal-Wallis and Wilcoxon's rank-sum tests. The AO CMF classification system was determined to be reliable and accurate for classifying mandibular fractures for most levels 2 and 3 variables. Level 2 variables had significantly higher interobserver reliability than level 3 variables (median kappa: 0.69 vs. 0.59, p < 0.001) as well as higher accuracy (median agreement: 94 vs. 91%, p < 0.001). Accuracy was adequate for most variables, but lower reliability was observed for condylar head fractures, fragmentation of condylar neck fractures, displacement types and direction of the condylar process overall, as well as the condylar neck and base fractures. Assessors with more clinical experience demonstrated higher reliability (median kappa high experience 0.66 vs. medium 0.59 vs. low 0.48, p < 0.001). Assessors with experience using the classification software also had higher reliability than their less experienced counterparts (median kappa: 0.76 vs. 0.57, p < 0.001). At present, the AO CMF classification system for mandibular fractures is suited for both clinical and research settings for level 2 variables. Accuracy and reliability decrease for level 3 variables specifically concerning fractures and displacement of condylar process fractures. This will require further investigation into why these fractures were characterized unreliably, which would guide modifications of the system and future instructions for its usage.

Abstract
Background: Mandibular fractures contribute to a substantial proportion worldwide. Various variables related to mandibular fractures such as demographics, etiology, pattern of fracture, and treatment have been studied, but fewer reports on their correlations are published. Hence, this study attempts to understand these factors which can be useful for setting up clinical and research priorities. Aim: The purpose of this retrospective study is to establish a correlation between different factors associated with mandibular fractures. Materials and Methods: A database of 277 patients between July 2011 and October 2018 with mandibular fractures was retrospectively retrieved. Information on age, gender, etiology, pattern of fracture, and treatment done was obtained, tabulated, and analyzed statistically. Entities such as age and gender, age and cause, gender and cause, site of fracture and cause, site of fracture and side, site of fracture and treatment done, and site of fracture and gender were correlated. Statistical Analysis Used: Descriptive and analytical statistics were calculated using the SPSS version 20 using Chi-square tests which include Pearson's Chi-square and likelihood ratio. Results: In a total of 277 patients, a statistically significant correlation was found between age and the etiologic agent, site and side of fracture, and site of fracture and the treatment done with value of P < 0.05. Conclusion: A definite correlation between multitude of overlooked relevant co-factors has been studied which can provide an operating surgeon, a valuable impetus to be more vigilant in terms of medicolegal record maintenance, diagnosis, and possible clinical strategy for the treatment of mandibular fractures.

Abstract
Objectives: The objective was to evaluate the age, gender distribution, side and site distribution, etiology, and common patterns of the mandibular fractures. Materials and Methods: This was a systematic retrospective review of records of 94 patients with 162 mandibular fractures treated in a single institution. Results: Of 94 patients, 72 male and 22 female patients belong to the age group of 4–62 years (average 31.57 years). Among the various etiologies, i.e., assault, road traffic accident (RTA), self-fall, workplace injury, and sports-related injury, RTA accounts for 62.76% and self-fall for 18.08% of cases. Of the 100 fractures analyzed, 46% are unilateral fractures and 54% are bilateral. Sides affected among these are left (58%), right (39%), and symphysis or midline (3%). The site distribution is as follows: symphysis – 5; parasymphysis – 64; body – 13; angle – 43; and subcondylar – 37. The most common fracture pattern is the ipsilateral parasymphysis with contralateral angle (21 cases). Open reduction and internal fixation was the predominant modality of treatment. Complications were observed in 27.65% of patients. Conclusion: Surveys play a vital role in better understanding the biomechanics of the mandible fractures. Furthermore, analysis of the treatment modalities used and their respective outcomes are of paramount importance in guiding surgeons to evaluate their efficacy.

Abstract
Objective:To observe the effect of NGF on the expression of BMP-2 in rabbit model and explore the molecular mechanism of NGF which might promote the healing of mandibular fracture with nerve injury. Method:The 48 New-Zealand white rabbits were randomly divided into the experimental group (mandibular fracture+to cut off the nerve bundle+NGF by GS), the control group (mandibular fracture+to cut off the nerve bundle+NS by GS), the blank group (mandibular fracture+to cut off the nerve bundle) and the full-set group (mandibular fracture+retains the nerve bundle). After 2 weeks, 4 weeks, 6 weeks and 8 weeks, 3 rabbits were sacrificed in each group for HE staining and RT-PCR, respectively. Result:HE staining showed the osteogenesis phenomenon: the experimental group was clearer than control group, the full-set group was clearer than the blank group and the control group is similarly to the blank group. RT-PCR results revealed that there was a statistically significance in the early stage. The expression of BMP-2 peaked in 2 weeks and decreased later with time. Conclusion:The local application of NGF can prompt BMP-2 expression in the early stages of the mandibular fracture with partial nerve injury healing and this may be one of the molecular mechanisms.

Abstract
Background Mandibular condylar fractures commonly occur after trauma and account for 25 to 35% of all mandibular fractures; its appropriate therapy still remains a point of controversy in children. The purpose of this paper is to describe the treatment of an 11-years-old male patient affected by neck-condylar fracture as result of trauma in evolutive age. Methods No surgical treatment was performed. A functional therapy was applied with a jaw splint. A closed treatment for mandibular condyle fractures was preferred because the amount of condylar displacement wasn’t considerable. Results The early treatment with functional therapy generated a functional adaptation of the condyle in the glenoid fossa and a normal mandibular function. After a 12-month follow-up the fracture resolution and an optimal condylar position were recorded. Conclusions The current case report and literature review showed that non-surgical therapy of neck-condylar fracture in a child with lower resin splint can restore mandibular movements and aesthetics. Facial growth after one year treatment resulted normal. A conservative treatment may be appropriate for children in selected cases with minimally displaced condyle.

Abstract
The aim of this prospective study was to appraise the role of embrasure wiring in the treatment of mandibular fractures over the arch bar as adjunctive techniques of maxillomandibular fixation (MMF). This study was conducted on 40 patients who were surgically treated for mandibular fractures with accessory use of MMF (embrasure: group A vs. arch bars: group B). All patients were evaluated for demographic data, etiology, and location of fracture. Characteristically, the complications, including wire injury, infection, and malocclusion, were recorded. The data were analyzed using Student's t -test and chi-square test as appropriate. Statistical significance was set at p < 0.05). In this study, data from 40 patients were included. In group A (embrasure wiring), time required for placement of MMF was significantly less than (7.85 ± 0.81 minutes) that in group B, and also there was less incidence of wire prick to the operator in group A than in group B ( p < 0.05). However, in terms of wire prick and malocclusion, no statistically significant difference was noted in groups A and B ( p > 0.05). Patient treated with embrasure wiring intermaxillary fixation had better outcomes especially in terms of time of placement and less incidence of wire prick injury when compared with arch bar.

Abstract
Objective The aim is to analyze the pattern of maxillofacial injuries and treatment outcomes in the past 15 years (2002-2016). Materials and Methods: One thousand eight hundred and fifty patients from two tertiary referral center hospitals were studied retrospectively in which the age, sex, etiology, site of fracture, and treatment modality was recorded. Results One thousand two hundred and twenty-eight males and 622 females were operated between 2002 and 2016. Mean age was 29 ± 17.2 years. Maximum incidence was seen in the age group of 16-30 years in males, whereas in females, the predominance of trauma was seen in both 16-30 and 31-45 age groups. Road traffic accidents were responsible for the majority of fractures (42.2%), followed by assaults (26.4), sports injuries (17.6%), and fall (10.7%). Maximum fractures were of the mandible (53.5%) followed by midface (25.6%) and panfacial trauma (20.8%). Nearly 53.6% of patients underwent open reduction, and internal fixation (ORIF), 34.2% managed by the closed method and 12.1% were kept under observation. Conclusion This study verified a young male predominance, a shift toward more assault related fractures, especially in females. Mandibular fractures were the most common of all. Moreover, the changing trend toward ORIF in the past 15 years.

Abstract
Aim: The aim of this study was to give an insight into the retrospective analysis of a number of maxillofacial trauma cases reported to our institute and research center. Materials and Methods: The data for this study was obtained from the medical records and outpatient prescription slips of cases treated at the Oral and Maxillofacial Surgery Department from 2010 to 2016. Etiology, age, gender, pattern of fracture, and surgical treatment modalities undertaken in these patients were recorded. Results: A total of 353 maxillofacial trauma patients with mean age of 40 years, treated at our institute were evaluated from 2010 to 2016. Mandible was the most commonly fractured bone with parasymphysis as the most frequent site. Majority of victims were males (male:female ratio of 4:1) and also in the third decade of life. This study showed that 73% patients were treated by open reduction and internal fixation (ORIF), 25.8% by intermaxillary fixation (IMF) and Stabilization of fracture mandible with acrylic splint and circummandibular wiring was done in 0.8% pediatric patients. Conclusion: It was concluded that road traffic accidents were reported as the leading cause of maxillofacial fractures followed by assault, falls, and familial dispute. Maxillofacial surgeons as health care providers must continue their ‘face it’ campaign to decrease the incidence of road traffic accidents. Open reduction and internal fixation remains the gold standard treatment modality.

Abstract
BACKGROUND/AIM There are no data available to show whether there is a relationship between mandibular fractures and isolated fractures of the posterior and/or lateral walls of the maxillary sinus. The aim of this study was to determine whether there is a coincidence between these fracture patterns. METHODS Four hundred large volume cone beam computed tomography scans (CBCT) of patients with a fracture of the mandible between 2008 and 2013 were analyzed retrospectively. Patients with multiple midfacial fractures were excluded. The radiographic findings were correlated with epidemiological and clinical data of the patients such as gender, age, treatment methods, or complications. RESULTS The most frequent fracture sites of the mandible were the jaw angle, the parasymphysis region, and the condyle. Nineteen of the 400 patients (4.75%) had an isolated fracture of the lateral and/or posterior maxillary sinus. Odds-ratio analysis revealed a high tendency for significant correlation of condylar process fractures with isolated maxillary sinus fractures. Chi-square test demonstrated a P-value near statistical significance (P=.054). No other fracture site of the mandible could be associated with an isolated fracture of the maxillary sinus. CONCLUSION A condylar process fracture of the mandible after trauma without any further injury of the midface may be associated with an isolated fracture of the lateral and/or posterior maxillary sinus.

Abstract
OBJECTIVE This retrospective study evaluated the use of a single miniplate for the treatment of mandibular angle fractures (MAF). METHODS Fifty patients with 53 MAF were treated by open reduction and internal fixation with the use of a single miniplate and were analyzed in this study. RESULTS Five patients with MAF had postoperative complications that required additional procedures. Three patients had postoperative infection, one patient complained of malocclusion in the first postoperative week, and one patient had miniplate exposure three months after surgery. Every additional procedure was performed in the office under local anesthesia without disruption of the initial fracture treatment. Postoperative maxillomandibular fixation (MMF) was performed in four patients. Treatment of MAF using a single miniplate was effective, with low morbidity and with low rates of postoperative complications. MAF can be treated without MMF, and stability is improved when long miniplates are used. CONCLUSIONS The use of a single miniplate is therefore encouraged. However, postoperative MMF should be considered with the presence of little contact between bone segments, malocclusion, or extensive tooth loss.

Abstract
INTRODUCTION The purpose of the study was to analyze whether adequate fracture fixation can be achieved by three-dimensional (3D) stainless steel mini-plates its ease of placement, whether the patient can resume function early and to find out the need to do intermaxillary fixation. MATERIALS AND METHODS In the prospective study, we treated 12 patients and 17 fractured sites using 3D mini-plates. Once fracture reduction was achieved temporary intermaxillary fixation (IMF) was done occlusion was achieved and the fractured segments were fixed using 3D plates either 4-holed or 6-holed of 2.5 mm thickness and 6-8 mm length screws. IMF was removed subsequently. CONCLUSION In none of the cases non-union or malocclusion was noted. Similarly except for 2 cases which had associated subcondylar fractures IMF was not done postoperatively. The patients were able to achieve function immediately with a reasonable level of success. The interincisal opening ranged from 18 to 23 mm in the first week to 40-56 mm after 1 month.

Abstract
OBJECTIVES: To characterize the oral motor system of adults with facial injuries and to compare the oral motor performance/function between two different groups. METHODS: An observational, descriptive, cross-sectional study was conducted in 38 patients presenting with facial trauma who were assigned to the Division of Orofacial Myology of a Brazilian School Hospital. Patients were divided into two groups: Group 1 (G1) consisted of 19 patients who were submitted to open reduction of at least one facial fracture, and Group 2 (G2) consisted of 19 individuals who were submitted to closed fracture reduction with maxillomandibular fixation. For comparison purposes, a group of 19 healthy volunteers was recruited. All participants underwent a clinical assessment that included an oral motor evaluation, assessment of the mandibular range of motions, and electromyographic assessment of the masticatory muscles. RESULTS: Clinical assessment of the oral motor organs indicated that G1 and G2 presented deficits related to the posture, position, and mobility of the oral motor organs. Patients also presented limited mandibular ranges of movement. Deficits were greater for individuals in G1, especially for maximal incisor opening. Additionally, patients in G1 and G2 presented a similar electromyographic profile of the masticatory muscles (i.e., patients with facial fractures presented lower overall muscle activity and significant asymmetrical activity of the masseter muscle during maximum voluntary teeth clenching). CONCLUSION: Patients in G1 and G2 presented similar functional deficits after fracture treatment. The severity of facial fractures did not influence muscle function/performance 4 months after the correction of fractures.

Abstract
Severely atrophic mandible fractures are frequently a challenge to treat. Virtual surgical planning (VSP) uses three-dimensional computed tomographic (CT) scans that can be translated into stereolithographic models to fabricate surgical templates, facilitating intraoperative procedures. The purpose of this article is to describe the reconstruction of two cases of severe atrophic mandible fracture using VSP. Two elderly edentulous/partially dentate patients who presented with fractures of their mandibles and who underwent reconstruction using VSP were included. Both had Class III atrophy at the region of the fracture. While both fractures were complex, the mechanism of injury differed with one being a tractor accident and the other being a pathologic fracture. Both patients presented with critical medical conditions. CT scans were obtained on both. The displaced segments were aligned virtually using mirror images and the midline of the maxilla. Three-dimensional models were fabricated to allow preoperative contouring of 2.5-mm reconstruction plates. Patients were operated under general anesthesia and fractures reduced and stabilized with 2.5-mm reconstruction plates placed at the lateral border of the mandible. Average treatment time for both patients was a little over 2 hours. There was good reduction with both. VSP is a valuable tool to assess and reduce complex fractures with less surgical time and predictable results.

Abstract
BACKGROUND/AIMS There is a paucity of literature on external auditory canal (EAC) fractures secondary to maxillofacial trauma, with most of the literature on EAC fractures consisting of isolated case reports. To the authors' best knowledge, this is the first study to use cone beam computed tomography to evaluate the EAC region. The aim of this study was to assess the prevalence of external auditory canal (EAC) fracture following maxillofacial trauma and to evaluate the association between EAC fracture and other maxillofacial fractures and the region of trauma. MATERIALS AND METHODS One hundred patients were prospectively evaluated over 6 months from February to August 2016. The patients were referred for CBCT regarding temporomandibular joint or condylar fractures following maxillofacial trauma. Two observers (both experienced radiologists) assessed the EAC and associated fractures in the maxillofacial region. RESULTS External auditory canal (EAC) fracture was confirmed in 32% of the patients. Of the EAC fractures, 68.75% and 31.25% were associated with mandibular fractures and non-mandibular fractures, respectively. Of the EAC fractures, 68.75% were single fractures and 31.25% of patients had multiple comminuted fractures. Significant association was observed on cross-tabulation of the fractured region and region of trauma with the presence of EAC fracture using chi-square test. CONCLUSION External auditory canal (EAC) fracture is associated with maxillofacial fractures with increased incidence in mandibular fractures compared to non-mandibular fractures.

Abstract
BACKGROUND/AIM The decision to retain or extract teeth in the line of mandibular fractures has been a subject of debate in the scientific literature, and there is a need for further evidence to clear this issue. Thus, the aim of this study was to investigate the effects on healing of teeth in the line of mandibular fractures in order to contribute to the field. MATERIAL AND METHODS The case notes of 100 patients with teeth in the line of 106 mandibular fractures were reviewed. Open reduction and rigid internal fixation (ORIF) was used if elastic intermaxillary reduction failed to achieve a satisfactory occlusion and/or anatomical reduction in the fragments as assessed by orthopantomogram (OPG) and clinical examination. The remaining cases had maxillomandibular fixation (MMF) with an arch bar and bridle wire. RESULTS Three of the 106 teeth involved in the fracture lines healed with complications. In the cases where the teeth had been removed prior to fracture treatment, or in cases of delayed extractions, no complications were noted. CONCLUSION The factors which should be considered for removal include the condition of the teeth and alveolar bone, the timing and the type of treatment. This decision should be made on an individual basis considering potential risks to avoid complications.
