Abstract
Traumatic brain injuries (TBIs) associated with maxillofacial fractures (MFFs) are a public health concern worldwide, especially among adult-aged males. There is an urgent need for early detection of associated TBIs in patients with MFFs during the initial assessment and treatment stage to reduce morbidity and mortality. The objective of the present study was to systematically review the literature to determine specific MFF situations associated with TBIs and to identify the factors associated with TBIs in patients with MFFs. The protocol was developed in accord with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and was registered to the International Prospective Register of Systematic Reviews (PROSPERO) under the registration number CRD42020155912. Overall, of 26,774 patients recorded, 13,667 patients (51.04%) sustained MFFs with an associated TBI. The male to female ratio was 4.8:1. RTA was the most common cause. The most common TBIs were concussions, contusions, and closed brain injuries. Within the limits of this study, it was concluded that TBI-related MFFs should be suspected whenever maxillary or mandibular bone fractures occur, especially among adults, males, and people with injuries caused by RTAs and assaults. There is a need to increase the awareness of maxillofacial surgeons on the possible associations of combined maxillofacial trauma and brain injuries.

Abstract
Study Design Retrospective study. Objective The purpose of this study was to retrospectively analyze the prevalence, pattern, diagnosis, and treatment of the facial fractures falling under ambit of facial plastic surgery in a multi-specialty hospital at India from the year 2006-2019. Methods This retrospective study analyzed 1508 patients, having orbital fractures (from 2006 to 2019) for demographic data, cause of trauma, type of fracture, and the treatment given. The data were compiled in excel and analyzed by using SPSS version 21.0. Results Out of these 1508 patient (1127 (74.73%)-males and 381 (25.27%)-females), the etiology of injuries was Road traffic accident (RTA) (49.20%), assault (26.52%), and sports injuries (11.47%). The most common fracture pattern was Isolated Orbit and/or Orbital Floor fracture in 451 patients (32.08%), followed by Mid-facial fractures (21.93%). Also, 105 patients (6.96%) experienced ocular/retinal trauma along with other fractures. Conclusions Orbit, peri-ocular, and mid-face trauma comprised a large position of this study. It requires a great deal of expertise to treat such complex trauma, which is not covered in one specialty alone. Hence, a holistic approach of craniofacial fracture management, rather than limiting these skills to water-tight craniofacial compartments becomes necessary. The study highlights the critical need of multidisciplinary approach for predictable and successful management of such complex cases.

Abstract
A specific design of craniofacial implant model is vital and urgent for patients with traumatic head injury. The mirror technique is commonly used for modeling these implants, but it requires the presence of a healthy skull region opposite to the defect. To address this limitation, we propose three processing workflows for modeling craniofacial implants: the mirror method, the baffle planner, and the baffle-based mirror guideline. These workflows are based on extension modules on the 3D Slicer platform and were developed to simplify the modeling process for a variety of craniofacial scenarios. To evaluate the effectiveness of these proposed workflows, we investigated craniofacial CT datasets collected from four accidental cases. The designed implant models were created using the three proposed workflows and compared to reference models created by an experienced neurosurgeon. The spatial properties of the models were evaluated using performance metrics. Our results show that the mirror method is suitable for cases where a healthy skull region can be completely reflected to the defect region. The baffle planner module offers a flexible prototype model that can be fit independently to any defect location, but it requires customized refinement of contour and thickness to fill the missing region seamlessly and relies on the user's experience and expertise. The proposed baffle-based mirror guideline method strengthens the baffle planner method by tracing the mirrored surface. Overall, our study suggests that the three proposed workflows for craniofacial implant modeling simplify the process and can be practically applied to a variety of craniofacial scenarios. These findings have the potential to improve the care of patients with traumatic head injuries and could be used by neurosurgeons and other medical professionals.

Pattern of associated brain injury in maxillofacial trauma: a retrospective study from a high-volume centre. Br J Oral Maxillofac Surg 2022; 60:1373-1378. [PMID: 36253321 DOI: 10.1016/j.bjoms.2022.09.002] [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: 05/23/2022] [Revised: 08/20/2022] [Accepted: 09/21/2022] [Indexed: 12/31/2022]
Abstract
The incidence of head injury in maxillofacial trauma patients varies widely in the literature. A good understanding of the patterns of association between these injuries would aid in efficient multidisciplinary treatment. The aim of this study therefore was to understand the associations between head injury and facial trauma by retrospectively analysing the records of patients seen at a tertiary care trauma centre. Demographic data were also described. Records of 4350 facial trauma patients over a five-year period were reviewed. A total of 3564 (81.9%) patients were victims of motor vehicle accidents (MVA). Male patients predominated, comprising 3711 (85.3%), and 36.6% were in the third decade of life. Facial fractures were seen in 2120 (48.7%), the most common being zygomatic fractures (60%). At the time of trauma, 2383 (57.3%) patients were under the influence of alcohol, and 2821 (87.8%) victims of two-wheeler MVAs were not using their helmet. Of all patients, 29.75% sustained a traumatic brain injury (TBI). Midface fractures were strongly associated with TBI. Maxillofacial injury may be considered a risk factor for TBI, and as such should immediately be suspected and investigated in all patients. Prompt recognition and management can improve outcomes in these patients.

Abstract
Road traffic accidents (RTA) are the major cause of maxillofacial injuries (MFIs) in developing countries (Akama et al. 2007). Road traffic accidents were reported to be the 9th most common cause of death and morbidity in the world and are expected to rise to 3rd position by 2020 (Peden et al. 2002). Maxillofacial injuries remain a serious clinical problem because of the involvement of complex anatomic region. Facial fractures occur most commonly in males in the third decade of life (Motamedi et al. 2014). The goal of treatment in facial fractures is to achieve anatomic reduction and restore function while increasing patient comfort and making postoperative care easier (Lachner et al. 1991). The aim of the study was to evaluate the cases of Maxillofacial injuries with the existing literature on its different presentation and management. An observational study was done from the patients of RTA with Maxillofacial injuries in ENT department and trauma centre of Sir T General hospital and Government Medical College, Bhavnagar for a period of 2 year. A total of 315 patients were included. Males are more commonly affected than females. The main etiological factor for RTA was motorcycle accidents. The trend of MFIs especially due to MCAs was on the rise after the age of 20 year. Anatomically the lower 1/3 section of the face was the most affected. Mandibular fractures were most common isolated fracture in MFIs. Open reduction and internal fixation (ORIF) by plating and screw was the treatment of choice for displaced, comminuted and multiple fractures of face. Facial trauma remains a major source of injury in all parts of the world. Its management involves many disciplines in the hospital setting, but knowledge of occlusion, the masticatory apparatus and anatomy is important for the best outcomes. This study was an analysis of demographic variables and outcome of the management adopted in patients presented to our department.

A systematic review and meta-analysis of factors involved in bone flap resorption after decompressive craniectomy. Neurosurg Rev 2022; 45:1915-1922. [PMID: 35061139 DOI: 10.1007/s10143-022-01737-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 10/18/2021] [Accepted: 01/11/2022] [Indexed: 02/02/2023]
Abstract
Decompressive craniectomy (DC) is effective in controlling increasing intracranial pressure determined by a wide range of conditions, mainly traumatic brain injury (TBI) and stroke, and the subsequent cranioplasty (CP) displays potential therapeutic benefit in terms of overall neurological function. While autologous bone flap (ABF) harvested at the time of DC is the ideal material for skull defect reconstruction, it carries several risks. Aseptic bone flap resorption (BFR) is one of the most common complications, often leading to surgical failure. The aim of our study was to systematically review the literature and carry out a meta-analysis of possible factors involved in BFR in patients undergoing ABF cranioplasty after DC. A systematic review and meta-analysis was performed in accordance with the PRISMA guidelines. Different medical databases (PubMed, Embase, and Scopus) were screened for eligible scientific reports until April 30th 2021. The following data were collected for meta-analysis to assess their role in BFR: sex, age, the interval time between DC and CP, the presence of systemic factors, the etiology determining the DC, CP surgical time, CP features, VP shunt placement, CP infection. Studies including pediatric patients or with less than 50 patients were excluded. Fifteen studies were included. There was a statistically significant increased incidence of BFR in patients with CPF > 2 compared to patients with CPF ≤ 2 (54.50% and 22.76% respectively, p = 0.010). TBI was a significantly more frequent etiology in the BFR group compared to patients without BFR (61.95% and 47.58% respectively, p < 0.001). Finally, patients with BFR were significantly younger than patients without BFR (39.12 ± 15.36 years and 47.31 ± 14.78 years, respectively, p < 0.001). The funnel plots were largely symmetrical for all the studied factors. Bone flap fragmentation, TBI etiology, and young age significantly increase the risk of bone resorption. Further studies are needed to strengthen our results and to clarify if, in those cases, a synthetic implant for primary CP should be recommended.

Abstract
Trauma induced injuries of the mouth, jaw, face, and related structures present unique clinical challenges due to their large size and complex geometry. Growth factor signaling coordinates the behavior of multiple cell types following an injury, and effective coordination of growth factor availability within a biomaterial can be critical for accelerating bone healing. Mineralized collagen scaffolds are a class of degradable biomaterial whose biophysical and compositional parameters can be adjusted to facilitate cell invasion and tissue remodeling. Here we describe the use of modified simulated body fluid treatments to enable sequential sequestration of bone morphogenic protein 2 and vascular endothelial growth factor into mineralized collagen scaffolds for bone repair. We report the capability of these scaffolds to sequester 60–90% of growth factor from solution without additional crosslinking treatments and show high levels of retention for individual (>94%) and multiple growth factors (>88%) that can be layered into the material via sequential sequestration steps. Sequentially sequestering growth factors allows prolonged release of growth factors in vitro (>94%) and suggests the potential to improve healing of large-scale bone injury models in vivo. Future work will utilize this sequestration method to induce cellular activities critical to bone healing such as vessel formation and cell migration. Trauma induced injuries of the mouth, jaw, face, and related structures present unique clinical challenges due to their large size and complex geometry.![]()

Abstract
This study aims the in vivo biological characterization of an innovative minocycline delivery system, based on polymethylmethacrylate bone cement. Bone cements containing 1% or 2.5% (w/w) minocycline were formulated and evaluated through solid-state characterization. Biological evaluation was conducted in vivo, within a rat model, following the subcutaneous and bone tissue implantation, and tissue implantation associated with Staphylococcus aureus is challenging. The assessment of the tissue/biomaterial interaction was conducted by histologic, histomorphometric and microtomographic techniques. Minocycline addition to the composition of the polymethylmethacrylate bone cement did not modify significantly the cement properties. Drug release profile was marked by an initial burst release followed by a low-dosage sustained release. Following the subcutaneous tissue implantation, a reduced immune-inflammatory reaction was verified, with diminished cell recruitment and a thinner fibro-connective capsule formation. Minocycline-releasing cements were found to enhance the bone-to-implant contact and bone tissue formation, following the tibial implantation. Lastly, an effective antibacterial activity was mediated by the implanted cement following the tissue challenging with S. aureus. Kinetic minocycline release profile, attained with the developed polymethylmethacrylate system, modulated adequately the in vivo biological response, lessening the immune-inflammatory activation and enhancing bone tissue formation. Also, an effective in vivo antibacterial activity was established. These findings highlight the adequacy and putative application of the developed system for orthopedic applications.

Abstract
Implant osteoinduction and subsequent osteogenic activity are critical events that need improvement for regenerative healing of large craniofacial bone defects. Here we describe the augmentation of the mineral content of a class of mineralized collagen scaffolds under development for craniomaxillofacial bone regeneration via the inclusion of zinc ions to promote osteogenesis in vitro. Zinc is an essential trace element in skeletal tissue and bone, with soluble zinc being shown to promote osteogenic differentiation of porcine adipose derived stem cells. We report the development of a new class of zinc functionalized scaffolds fabricated by adding zinc sulfate to a mineralized collagen-glycosaminoglycan precursor suspension that was then freeze dried to form a porous biomaterial. We report analysis of zinc functionalized scaffolds via imaging (scanning electron microscopy), mechanical testing (compression), and compositional (X-ray diffraction, inductively coupled plasma mass spectrometry) analyses. Notably, zinc-functionalized scaffolds display morphological changes to the mineral phase and altered elastic modulus without substantially altering the composition of the brushite phase or removing the micro-scale pore morphology of the scaffold. These scaffolds also display zinc release kinetics on the order of days to weeks and promote successful growth and pro-osteogenic capacity of porcine adipose derived stem cells cultured within these zinc scaffolds. Taken together, we believe that zinc functionalized scaffolds provide a unique platform to explore strategies to improve in vivo osteogenesis in craniomaxillofacial bone injuries models. STATEMENT OF SIGNIFICANCE: Craniomaxillofacial bone defects that arise from traumatic, congenital, and post-oncologic origins cannot heal on their own and often require surgical intervention. We have developed a class of mineralized collagen scaffolds that promotes osteogenesis and bone regeneration. Here we describe the inclusion of zinc sulfate into the mineralized collagen scaffold to improve osteogenesis. Zinc functionalized scaffolds demonstrate altered crystallite microstructure but consistent Brushite chemistry, improved mechanics, and promote zinc transporter expression while supporting stem cell viability, osteogenic differentiation, and mineral biosynthesis.

Abstract
Introduction: This prospective study highlights the pattern of oral and maxillofacial injuries in patients with associated craniocerebral injuries. Material and Methods: This was a prospective descriptive study conducted over a 22-month period. Information was collected using a structured questionnaire and analyzed using Statistical Package for Social Sciences (SPSS) Version 13 (SPSS Inc., Chicago, IL, USA) and Microsoft Office Excel 2007 (Microsoft, Redmond, WA, USA). Test of statistical significance was set at 0.05. Results: Three hundred and three consecutive patients were studied and this consisted of 254 males and 49 females. The difference in the gender distribution was statistically significant (p = 0.008). Road traffic crashes (n = 262; 86.5%) was the most common cause of injury and soft tissues orofacial injuries accounted for 61.7% of injuries. Le Fort II fractures were the major skeletal injuries. Glasgow Coma Score (GCS) of 13–15 had the highest frequency (n = 157; 53.4%). Intracerebral haemorrhage was the most common cerebral injury recorded and the commonest complication noted was dysocclusion. Discussion: Although middle third facial fractures were the most common skeletal injury, fractures of the upper third facial skeleton appear to be associated with lower GCS. Conclusion: Fractures of the facial skeleton are fairly common in craniocerebral injuries.

Abstract
OBJECTIVE The aim of this study was to investigate the long-term therapeutic efficacy of cranioplasty with autogenous bone flaps cryopreserved in povidone iodine and explore the risk factors for bone resorption. METHODS Clinical data and follow-up results of 188 patients (with 211 bone flaps) who underwent cranioplasty with autogenous bone flaps cryopreserved in povidone-iodine were retrospectively analyzed. Bone flap resorption was classified into 3 types according to CT features, including bone flap thinning (Type I), reduced bone density (Type II), and osteolysis within the flaps (Type III). The extent of bone flap resorption was graded as mild, moderate, or severe. RESULTS Short-term postoperative complications included subcutaneous or extradural seroma collection in 19 flaps (9.0%), epidural hematoma in 16 flaps (7.6%), and infection in 8 flaps (3.8%). Eight patients whose flaps became infected and had to be removed and 2 patients who died within 2 years were excluded from the follow-up analysis. For the remaining 178 patients and 201 flaps, the follow-up duration was 24-122 months (mean 63.1 months). In 93 (46.3%) of these 201 flaps, CT demonstrated bone resorption, which was classified as Type I in 55 flaps (59.1%), Type II in 11 (11.8%), and Type III in 27 (29.0%). The severity of bone resorption was graded as follows: no bone resorption in 108 (53.7%) of 201 flaps, mild resorption in 66 (32.8%), moderate resorption in 15 (7.5%), and severe resorption in 12 (6.0%). The incidence of moderate or severe resorption was higher in Type III than in Type I (p = 0.0008). The grading of bone flap resorption was associated with the locations of bone flaps (p = 0.0210) and fragmentation (flaps broken into 2 or 3 fragments) (p = 0.0009). The incidence of bone flap collapse due to bone resorption was higher in patients who underwent ventriculoperitoneal (VP) shunt implantation than in those who did not (p = 0.0091). CONCLUSIONS Because of the low incidence rates of infection and severe bone resorption, the authors conclude that cranioplasty with autogenous bone flaps cryopreserved in povidone-iodine solution is safe and effective. The changes characteristic of bone flap resorption became visible on CT scans about 2 months after cranioplasty and tended to stabilize at about 18 months postoperatively. The bone resorption of autogenous bone flap may be classified into 3 types. The rates of moderate and severe resorption were much higher in Type III than in Type I. The grade of bone flap resorption was associated with bone flap locations. Fragmented bone flaps or those implanted in patients treated with VP shunts may have a higher incidence of bone flap collapse due to bone resorption.

Abstract
BACKGROUND Maxillofacial fractures occur in a significant proportion worldwide and can occur as an isolated injury or in combination with other severe injuries including cranial, spinal, and upper and lower body injuries requiring prompt diagnosis with possible emergency interventions. The epidemiology of facial fractures varies with regard to injury type, severity, and cause and depends on the population studied. Hence, understanding of these factors can aid in establishing clinical and research priorities for effective treatment and prevention of these injuries. MATERIALS AND METHODS In this present retrospective study, we provide a comprehensive overview regarding cranio-maxillofacial trauma on 3611 patients to assist the clinician in assessment and management of this unique highly specialized area of traumatology. A preformed pro forma was used to analyze the medical records of patients treated for facial trauma in The Department of Oral and Maxillofacial Surgery, Meenakshi Ammal Dental College and Hospital, Chennai. The distribution according to age, gender, etiology, type of injury, time interval between accident and treatment, loss of consciousness, facial bones involved, pattern of fracture lines, treatment offered, and postoperative complications were recorded and evaluated. RESULTS We inferred male patients sustained more injuries mostly in the third decade of age. Road traffic accidents were the most common cause of injury. Mandible was the most commonly fractured bone in the facial skeleton. Soft tissue injuries occurred more in road traffic accidents and upper lip was the commonest site of injury. CONCLUSION Our study provides insights into the epidemiology of facial injuries and associated factors and can be useful not only in developing prevention strategies but also for grading the existing legal regulations and also for framing a more effective treatment protocol.

Abstract
BACKGROUND Traumatic brain injury (TBI) is one of the leading causes of death. Evidence-based guidelines for TBI care have been widely discussed, but in-hospital treatment and outcome of these patients has been highly variable especially in developing countries like India. OBJECTIVES To evaluate the epidemiology and outcome of patients with head injuries at a Level 1 trauma center in India. MATERIALS AND METHODS In this retro-prospective study, all patients with head injury who were admitted in the department of neurosurgery over a 15 months period (November 2007-January 2009) were included in the study. Post-resuscitation GCS was used for categorizing the severity of head injuries and outcome was assessed at discharge using GOS. All patients were managed as per laid down departmental protocols. RESULTS A total of 2068 patients of head injury were admitted during the study period. The mean age was 24 years (range 1-85). 71.4% were male and 28.6% were female. The most commonly involved age group was 20-40 years (43%) and the most common mode of injury was road traffic accidents (64%). 53% of the patients had severe head injury (GCS ≤ 8), 18% had moderate head injury (GCS 9 ≤ 13) and 29% had minor head injuries (GCS ≥ 14). The mean hospital stay was 14 days (range 1-62 days). Overall in-hospital mortality was 22% (454 cases). 39% died within 48 hours of injury. 2% of minor, 12% of moderate and 36% of severe head injured patients expired; Mortality was 38% in children (≤12 years). Amongst those who survived, 45% had good outcome (GOS 4 or 5), 13% were severely disabled (GOS 3) and 19% were vegetative (GOS 2). CONCLUSIONS This is the one of the largest single center study on severe head injuries and shows enormity of the problem facing developing countries like India.

Abstract
INTRODUCTION It is well-known that severe traumatic brain injuries (TBI) have a poor outcome. However, what is not well-known is the outcome for those who survive but remain unconscious at the time of discharge from the hospital. AIMS AND OBJECTIVES To assess the outcome of severe TBI patients who have a motor response of M5 or lower on the Glasgow coma score (GCS) at discharge from a single centre in India. MATERIALS AND METHODS In this retrospective study carried at one trauma centre in India, a prospectively maintained neurotrauma registry was queried from May 2010 to February 2013 for patients who had severe traumatic brain injury (GCS ≤ 8) at admission and had a motor response of M5 or lower on the GCS at discharge. Demographic and clinical data were analyzed, and outcome Glasgow outcome scale (GOS) assessed at 6 months using a telephonic questionnaire. OBSERVATIONS AND RESULTS There were a total of 1525 patients with severe TBI in the study period. Of these 166 (10.9%) were unconscious (motor response M5 or lower on the GCS) at discharge from the hospital. 139 were males and 27 females with a mean age of 33.9 years. After a mean hospital stay of 24.31 days, the discharge motor score was M5 in 32 (19.3%), M4 in 44 (26.5%), M3 in 59 (35.5%), M2 in 44 (26.5%), and M1 in 9 (5.4%). Telephonic follow-up was available in 102 (61.4%) of the patients. 54 (52.9%) patients had died and 32 (31.4%) remained unconscious (vegetative) at 6 months. Only 16 patients (15.7%) had a good outcome (GOS 1-2) at 6 months following an injury. CONCLUSIONS This is the only study of its kind on patients who remain unconscious at discharge following severe TBI and reveals that around 50% will die and another 30% remains vegetative at 6 months of discharge. Only a small percentage (15% in our study) will become conscious and partially integrated in the society.

Abstract
AIM The present study was planned to investigate the etiology of injuries and to analyze correlation between clinical and radiological findings in cases of craniomaxillofacial trauma. STUDY DESIGN An 18 months cross-sectional study was done and 325 patients with maxillofacial fractures were analyzed from January 2013 to June 2014 who reported to the department of oral and maxillofacial surgery, Aligarh, Uttar Pradesh. Data was recorded in a preformed case sheet which included: patient's demographic data, cause of injury, type of injury, treatment plan. RESULTS Out of the 325 patients, 74.4 % were males with a male: female ratio of 2.91:1. The 21-30 year age group was found to be maximum. Road traffic accidents accounted for 71.3 %, followed by fall from height (19 %) and assault (9.5 %). Most commonly involved vehicles were two wheelers followed by public transport. Mandibular fractures (65 %) were most prevalent, followed by zygomaticomaxillary complex (44.27 %), parietal bone (48 %) and orbital fractures (21.3 %). Thirty-seven fractures (7.14 %) were missed clinically which were confirmed later by radiographic technique. Maximum were in cranium region (57 %) followed by mandible (27 %), mid face region (16.21 %). Thirty-three fractures (6.37 %) were overestimated or suspected clinically which could not be confirmed by radiographic technique. Maximum were in mandible (48.5 %) followed by mid face (36.33 %) and cranium (15.15 %). CONCLUSION The idea behind this article is to analyze the various trends and affecting factors and correlation between clinical and radiological findings. A better understanding of the above said would help in future treatment planning and management of facial injuries.

Abstract
INTRODUCTION This study aimed to use video analysis techniques to determine the velocity, impact force, angle of impact, and impulse to fracture involved in a video-recorded bicycle accident resulting in facial fractures. Computed tomographic images of the resulting facial injury are presented for correlation with data and calculations. To our knowledge, such an analysis of an actual recorded trauma has not been reported in the literature. MATERIALS AND METHODS A video recording of the accident was split into frames and analyzed using an image editing program. Measurements of velocity and angle of impact were obtained from this analysis, and the force of impact and impulse were calculated using the inverse dynamic method with connected rigid body segments. These results were then correlated with the actual fracture pattern found on computed tomographic imaging of the subject's face. RESULTS There was an impact velocity of 6.25 m/s, impact angles of 14 and 6.3 degrees of neck extension and axial rotation, respectively, an impact force of 1910.4 N, and an impulse to fracture of 47.8 Ns. These physical parameters resulted in clinically significant bilateral mid-facial Le Fort II and III pattern fractures. DISCUSSION These data confer further understanding of the biomechanics of bicycle-related accidents by correlating an actual clinical outcome with the kinematic and dynamic parameters involved in the accident itself and yielding a concrete evidence of the velocity, force, and impulse necessary to cause clinically significant facial trauma. These findings can aid in the design of protective equipment for bicycle riders to help avoid this type of injury.

Abstract
Introduction: Trauma is one of the leading causes of morbidity and mortality in the world and in India. Objective: To describe 1) selected epidemiological and clinical characteristics of persons with traumatic brain injury (TBI) who died within 24 h after admission to the emergency departments (EDs) of two medical facilities in rural India and 2) the methods used to transport these patients from the locale of the injury incident to the study sites. Materials and Methods: Medical records of all injured patients regardless of age or sex who died within 24 h after admission to both EDs during January 31, 2007 through December 31, 2009 were reviewed and abstracted. Demographic variables and information on prehospital care, time and mechanism of injury, mode of transport to EDs, and primary hospital resuscitation were abstracted and analyzed. Results: Of the 113 injured patients in this study, 42 had TBI and died within 24 h of ED admission. All of these TBI patients were transported to the ED by relatives or bystanders in non-ambulance vehicles. Most of the patients with TBI (78.5%) were 21-50-years-old; and overall 90.0% were males. Persons working near or along busy roads struck by vehicles accounted for 80.9% of all TBI cases. Severe TBIs were present in 97.6% of the patients; of these, 92.8% had a Glasgow Coma Scale (GCS) score of 3 on arrival. Other concurrent injuries included superficial lacerations (85.7%), facial injuries (57.1%), and upper (35.7%) and lower (30.9%) extremity fractures. Common lesions recognized on computed tomography (CT) scan were acute subdural hematoma (21.4%), subarachnoid hemorrhage with diffuse cerebral edema (16.6%), and skull base fracture with diffuse cerebral edema (14.2%); in 21.4% of cases, the CT scan were reported normal. Conclusion: Most of the TBI patients who died within 24 h after admission to EDs in this study were not transported to EDs in emergency medical vehicles; most were of working age (ages 20-50 years); were male; and were day laborers working on busy interstate roads where they were hit by vehicles.

Abstract
There is an upward trend in facial injuries following changes in population pattern, increasing industrialization and urbanization, hence maxillofacial trauma is becoming a burden and a leading medical problem in emergency rooms worldwide. This study was performed to evaluate the pattern of maxillofacial fractures, associated injuries, and treatment used at Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences (AIIMS), New Delhi, India, between January 2007 and June 2010. The study provides basis for establishment of trauma as major etiology of maxillofacial injuries and planning for preventive strategies. A retrospective study of patients seen and treated at JPNATC, AIIMS, New Delhi, between January 2007 and June 2010 was performed. Data extracted from patient records included etiology, age, sex, types and sites of fractures, treatment modality, and concomitant injuries. There were 795 fractures of the maxillofacial skeleton and 86 concomitant injuries from 542 patients. Road traffic accident (RTA) (56.8%) was the most common etiologic factor, followed by falls (22.3%) and fights (18.5%). The age range was from 3 to 75 years (mean, 34.7 years) with a peak incidence in the third decade with a male-to-female ratio of 3.7:1. The most common location of maxillofacial fractures was the mandible 615 (77%) and middle third 180 (23%). With regard to mandibular fractures, the body (29.6%) was the most common site, followed by the angle (24.4%), ramus (19.5%), dentoalveolar (14.6%), symphysis (11.0%), condyle (0.8%) while in the middle third, the nasal bone (36.7%) was the most common, followed by zygomatic bone (27.8), Lefort II (14.4), Lefort I (7.8%), dentoalveolar (10.0%), and Lefort III (3.3%). Majority of the patients were treated by open reduction and internal fixation (70.6). Concomitant injuries were 84 (10.8%) with orthopedic injuries accounting for the majority (63.9%). Head injury was associated in 16.3% of cases. RTA was the major etiologic factor of maxillofacial injuries in our setting and the young adult males were the main victims. Henceforth, establishment of regionalized, efficient, and focused trauma centers in various parts of the country particularly for acute trauma should be emphasized. Also, the laws regarding the precautions such as seat belts, speed limits, and traffic rules must be observed strictly to reduce the incidence of RTA.

Abstract
INTRODUCTION In spite of anatomic proximity of the facial skeleton and cranium, there is paucity of information in the literature regarding the relationship between head injuries and facial trauma. The objective of our investigation was to evaluate the pattern of head injuries in patients with maxillofacial trauma, and to study their relationship. MATERIAL AND METHODS We evaluated 2,692 patients with maxillofacial trauma admitted to the Besat hospital, Hamedan, Iran between 2007 and 2010. Patients with associated head injury (302 cases; study group) were compared with those without head injury (2,390 cases; control group). RESULTS In our cohort, the rate of head injuries associated with facial bone fractures was 23.3 %. The most common associated head injury was concussion, followed by cerebral contusion and skull fractures. In the unadjusted analysis, motorcycle and car accidents were significantly more frequent in the study group, while stumbling, sports injuries, and work-related injuries were significantly more common in the control group (p < 0.001). Except for Lefort III fractures which was not significantly different between groups, all facial fractures occurred more frequently in the study group (p < 0.001). Logistic regression analysis demonstrated that motorcycle accidents (211-fold), car accidents (139-fold), violence (69-fold), falls (66-fold), frontal sinus fractures (84.5-fold), and Lefort II fractures (27-fold) were the strongest predictors of head injuries. DISCUSSION Present study revealed that fracture of facial bones, especially bones that are in anatomic proximity to the cranium and need a high magnitude of trauma energy to be fractured, was marker for an increased risk of head injuries.

Abstract
Although orthopedic injury has been reported to be the most frequent injury associated with facial trauma, their relationship has not been sufficiently evaluated in the literature. To evaluate this relationship, we compared 263 patients with concomitant facial and orthopedic injuries with 2006 patients with facial injuries alone. The rate of associated orthopedic injuries was 11.5%. Motor vehicle accidents, falls, mandibular fractures, and Le Fort I fractures increased the chance of sustaining orthopedic injuries nearly 17-, 15-, 10-, 4.4-, and 4.5-fold, respectively. Most fractures occurred in large bones with their inherent potential to cause severe, life-threatening complications. The high rates of mortality and morbidities associated with orthopedic injuries and the frequent occurrence of these injuries in patients with facial trauma emphasize upon the fact that maxillofacial surgeons, residents, and trauma nurses need more training in early diagnosis and appropriate management of associated orthopedic injuries.

Abstract
BACKGROUND Zygomaticomaxillary complex fractures associated with ipsilateral naso-orbito-ethmoidal fractures are more complex injuries than isolated zygomaticomaxillary complex fractures. This injury pattern can have significant long-term morbidity if not recognized and treated appropriately during the initial operation. The purpose of this study is to compare mechanisms of injury, treatment, and outcome between patients with zygomaticomaxillary complex fractures and those with zygomaticomaxillary complex and ipsilateral naso-orbito-ethmoidal fractures. METHODS A 5-year retrospective review of all patients treated with zygomaticomaxillary complex fractures at a level I trauma center was performed. Computed tomographic scans were reviewed to divide patients into those with zygomaticomaxillary complex fractures alone and those with zygomaticomaxillary complex and ipsilateral naso-orbito-ethmoidal fractures. Demographics, treatment protocols, outcomes, complications, reoperations, and length of follow-up were identified for both groups and compared to determine differences between these populations. RESULTS A total of 245 patients were identified by the Current Procedural Terminology codes for zygomaticomaxillary complex fractures. One hundred eighty-five patients had zygomaticomaxillary complex fractures and 60 patients had zygomaticomaxillary complex/naso-orbito-ethmoidal injuries. The demographics for both populations were similar. There are differences between the groups with regard to mechanism of injury, operative findings, and techniques. The patients with zygomaticomaxillary complex/naso-orbito-ethmoidal fractures had higher rates of postoperative complications and deformities. CONCLUSIONS Patients who sustain a zygomaticomaxillary complex fracture associated with an ipsilateral naso-orbito-ethmoidal fracture have a higher incidence of postoperative complications and deformities. It is important to recognize this fracture pattern early to help minimize postoperative morbidity. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, II.

Abstract
Cranioplasty is a common, but formidable surgical procedure for neurosurgeons, in patients with scalp and / or calvarial defects. This procedure can be simple or complex. The main objectives of cranioplasty are: To achieve primary wound healing, obliterate dead space, and seal off sterile cranial areas from contaminated oronasal cavities, to restore the normal barriers protecting the intracranial structures (together with a satisfactory cosmetic result) and obtain a permanent or very durable reconstruction, using biologically inert materials, and also to restore the aesthetics. The greatest problem is selecting the optimum material for repair of the cranial defect. Many synthetic substitutions of the dura and bone are often used for reconstruction of the skull base; unfortunately, these methods bear significant disadvantages and can induce chronic inflammation, carry a high risk of infection, and are inferior to biological sources in terms of strength and sealing quality [with the exception of some materials, such as titanium mashes and CortossTM (Orthovita®, Malvern, USA), which are seen to have more strength than the thin split thickness calvarial bone]. The primary aim of this article is to review the basic principles to use the split calvarial graft for the reconstruction of the skull defect.

Abstract
OBJECTIVE The features of earthquake-related head injuries may be different from those of injuries obtained in daily life because of differences in circumstances. We aim to compare the features of head traumas caused by the Sichuan earthquake with those of other common head traumas using multidetector computed tomography. METHODS In total, 221 patients with earthquake-related head traumas (the earthquake group) and 221 patients with other common head traumas (the non-earthquake group) were enrolled in our study, and their computed tomographic findings were compared. We focused the differences between fractures and intracranial injuries and the relationships between extracranial and intracranial injuries. RESULTS More earthquake-related cases had only extracranial soft tissue injuries (50.7% vs. 26.2%, RR = 1.9), and fewer cases had intracranial injuries (17.2% vs. 50.7%, RR = 0.3) compared with the non-earthquake group. For patients with fractures and intracranial injuries, there were fewer cases with craniocerebral injuries in the earthquake group (60.6% vs. 77.9%, RR = 0.8), and the earthquake-injured patients had fewer fractures and intracranial injuries overall (1.5 + 0.9 vs. 2.5 +1.8; 1.3 + 0.5 vs. 2.1 + 1.1). Compared with the non-earthquake group, the incidences of soft tissue injuries and cranial fractures combined with intracranial injuries in the earthquake group were significantly lower (9.8% vs. 43.7%, RR = 0.2; 35.1% vs. 82.2%, RR = 0.4). CONCLUSION As depicted with computed tomography, the severity of earthquake-related head traumas in survivors was milder, and isolated extracranial injuries were more common in earthquake-related head traumas than in non-earthquake-related injuries, which may have been the result of different injury causes, mechanisms and settings.

Abstract
The ideal reconstructive material for cranioplasty is autogenous bone, however if it is not available the use of alloplastic materials is recommended. We present a case of 26-year-male patient who sustained compound depressed fracture of the frontal bone and associated anterior cranial fossa fracture following a road traffic accident. He was managed at hospital where the fractured bone fragments were removed but recently presented with watery discharge from nose (CSF rhinorrhoea) and cosmetic deformity of forehead. We describe the utilization of autogenous local frontal bone split calvarial graft for the reconstruction of the defect.

Abstract
UNLABELLED Facial traumas are frequent in emergencies, and they require the diagnosis of fractures and associated lesions. AIM To analyze epidemiological data concerning facial trauma care. MATERIALS AND METHODS Three hundred and fifty-five charts from patients with facial trauma treated by the Service of Otorhinolaryngology, from January 2002 to December 2008, were revised. The following data was collected: age, gender, etiology, anatomical localization of the fracture, associated injuries, alcohol consumption, treatment, and hospitalization. STUDY DESIGN A retrospective historical longitudinal study. RESULTS Most of the patients are young adult men (p<0.05) with a male:female ratio of 4:1(p<0.05). Interpersonal violence is the most prevalent cause of facial trauma (27.9%), followed by motor vehicle accidents (16.6%) (p<0.05). The mandible is the most prevalent facial bone fractured (44.2%), followed by nasal fracture (18.9%) (p<0.05). 41.1% of the patients consumed alcohol with a male:female ratio of 11.2:1 (p<0.05). Seventy-seven percent of the patients required surgical intervention (p<0.05) and 84.5% were hospitalized (p<0.05). CONCLUSION Young male adults are the most prevalent victims of facial trauma, and interpersonal violence is responsible for the majority of the facial injuries. Most of the cases of facial trauma are associated with the consumption of alcohol. Further studies will be necessary to provide a clear understanding of the trends in the etiology of facial trauma.
