ABSTRACT
BACKGROUND: Standing electric scooters (e-scooters) are a cost-effective and environmentally-friendly transport alternative, but also elicit substantial concern regarding associated craniofacial injuries. This study aims to describe the patient factors, procedural factors and post-operative outcomes of maxillofacial fractures caused by e-scooter accidents. METHODS: Retrospective chart review of patients aged 18 years or older who were surgically treated for these injuries in 2014-2020 at two Australian tertiary hospitals. RESULTS: There were 18 cases included. Most cases were male (66%). The mean age was 35 years. Common risk factors were alcohol use (86%) and lack of helmet use (62%). The most common fracture pattern was zygomatico-maxillary complex (ZMC) fractures (50%). There were no associated systemic injuries. Mean operation timing was 12 days post-injury for ZMC fractures and 3 days post-injury for condyle fractures. For ZMC fractures, the most common method of fixation was 2-point fixation (66%). For condyle fractures, the most common surgical approach was arch bars only (83%). Post-operative complications were reported in six cases, with malocclusion being the most common (n = 3). Revision surgeries were performed in two cases. CONCLUSIONS: Maxillofacial fractures associated with e-scooter accidents appear to be increasing in incidence. Robust longitudinal evaluations with larger sample sizes are required to better understand associated presentations, surgical approaches and post-operative complications.

Introduction: COVID-19 pandemic has had a significant impact on people's behavior. Aim: To evaluate the impact of the COVID-19 on the epidemiology of maxillofacial fractures surgically treated in a Cuban university hospital. Methods: This research involved a 4-year descriptive, comparative, retrospective and cross-sectional study. Patients surgically treated between March 1 and December 31, 2020 (COVID-19 period) were compared with those who had undergone surgery between the same date in the years 2017-2019 (non-pandemic period). Age, sex, residence, year, month, alcohol consumption at the time of trauma, etiology, fractures types, and number of fractures per patient were recorded. Results: A decline in patients with maxillofacial fractures in 2020 (n=25) was observed when compared to equivalent periods in the three previous years (2017: n=37; 2018: n=31; 2019: n=41), respectively, with an annual average reduction of 31.19 percent. Interpersonal violence was found to be the paramount etiological factor for maxillofacial fractures during the comparison periods (2017-2019); however, road traffic accident prevailed in the 2020 (n=12; 48 percent). There was a small increase in the number of alcohol-related fractures (56 percent in 2020 vs 46.34 percent, 41.94 percent, and 51.35 percent in 2019, 2018, and 2017, respectively). Conclusion: COVID-19 impacted on the epidemiology maxillofacial fractures surgically treated in this Cuban university hospital (AU)
Introducción: La pandemia de la COVID-19 ha tenido un impacto significativo en el comportamiento de la población. Objetivo: Evaluar el impacto de la COVID-19 en la epidemiología de las fracturas maxilofaciales tratadas quirúrgicamente en un hospital universitario cubano. Métodos: Esta investigación consistió en un estudio descriptivo, comparativo, retrospectivo y transversal de 4 años de duración. Se compararon los pacientes intervenidos quirúrgicamente entre el 1 de marzo y el 31 de diciembre de 2020 (periodo COVID-19) con los intervenidos entre la misma fecha en los años 2017-2019 (periodo no pandémico). Se registraron edad, sexo, residencia, año, mes, consumo de alcohol en el momento del traumatismo, etiología, tipos de fracturas y número de fracturas por paciente. Resultados: Se observó un descenso de pacientes con fracturas maxilofaciales en 2020 (n=25) en comparación con periodos equivalentes de los tres años anteriores (2017: n=37; 2018: n=31; 2019: n=41), respectivamente, con una reducción media anual del 31,19 poe ciento. Se observó que la violencia interpersonal fue el factor etiológico primordial de las fracturas maxilofaciales durante los periodos de comparación (2017-2019); sin embargo, el accidente de tráfico prevaleció en el 2020 (n=12; 48 por ciento). Hubo un pequeño aumento en el número de fracturas relacionadas con el alcohol (56 por ciento en 2020 frente a 46,34 por ciento, 41,94 por ciento y 51,35 por ciento en 2019, 2018 y 2017, respectivamente). Conclusiones: La COVID-19 impactó en la epidemiología de fracturas maxilofaciales atendidas quirúrgicamente en este hospital universitario cubano (AU)

PURPOSE: The geriatric population is a constantly growing population that is especially vulnerable to trauma. The primary purpose of this study was to determine what factors are associated with increased rates of hospital admission in geriatric patients who sustain craniomaxillofacial fractures secondary to falls. MATERIALS AND METHODS: This is a 5-year retrospective cross-sectional study that was conducted using the NEISS database. There were several, heterogenous predictor variables. The primary outcome variable was admission rate, which was used as a proxy to the severity of injury. Patient and injury characteristics were compared using chi-square and independent-sample t-tests. Binary logistic regression was conducted to determine the risk of hospital admission. RESULTS: The final sample included 2,879 cases in total. The mean age of the study sample was 78.8 years (SD, 8.6 years). Most patients were white (51.6%) females (64.2%) who were injured at their respective homes (58.7%). Relative to injuries that took place at a sports center, injuries that took place at the patient's home (OR, 2.52; P < .05) independently increased the risk for admission. Relative to maxilla fracture, orbital bone fracture (OR, 3.91; P < .05) was an independent risk factor for admission. Relative to lacerations, intracranial injuries (OR, 3.76; P < .01) increased the risk of admission. CONCLUSIONS: Craniomaxillofacial fractures that took place at the patients' home were at increased risk for admission. Orbital bone fractures and intracranial injuries were at increased risk for admission. From our, and other studies findings, screening and fall prevention interventions should be implemented amongst the geriatric population.

Introduction: facial injuries are a public health problem, both physically and psychologically, characterized by a variety of injuries and sometimes by severe esthetic or functional sequelae. The purpose of this study was to describe the epidemiological and tomodensitometric aspects of maxillofacial fractures in Mopti. Methods: we conducted a cross-sectional and descriptive study in the Department of Radiology of the Mopti Hospital from January 2019 to December 2019. All patients who had undergone maxillofacial CT scan for a trauma with fracture confirmed by CT scan during this period were included. The variables analyzed were age, sex, etiology and the types of fractures observed on CT scan. Data recording and analysis were carried out using SPSS version 20 and Excel 2013. Results: of a total of 120 patients, the mean age was 26.43 years with a standard deviation of 14.547. Men predominated (75%; n= 90). Road accidents were the leading cause of fractures (50%; n = 60). Occlusofacial fractures accounted for 38.33% (n= 46). Lefort II was the most common fracture (22.50%; n= 27). Conclusion: this study allowed us to identify the population groups most affected by maxillofacial fractures in the Mopti region: adolescents and young adults. Tomodensitometric results were dominated by occlusofacial fractures, in particular Lefort type II fractures.

OBJECTIVES: The aim of this study was to evaluate the prevalence of maxillary tuberosity fractures in an adult population and to examine the different risk factors associated with these fractures. MATERIALS AND METHODS: This is a retrospective study; data was collected from medical records of patients who underwent a non-surgical extraction of a maxillary third molar tooth between January 2017 and March 2019. All extractions were performed by 2 maxillofacial specialists. RESULTS: A total of 403 extracted maxillary third molar teeth were included in the study. Out of them 73 cases of tuberosity fractures were recorded (18.1%). No significant difference in the number of recorded fractures was found between the 2 surgeons. The mean age of patients was 32.8 ± 11.5. In the age group of 30 years and under a fractures rate of 12.1% was recorded compared to 25.0% in the age group of over 30 (P = 0.001). Divergent or extremely curved root morphology were associated with a higher risk for fractures (30.7%) compared to convergent root morphology (13.1%) ( P < 0.001). Borderline significance ( P = 0.069) was observed for extractions of teeth with caries lesions (21.9%) compared to teeth with no caries lesions (14.6%). CONCLUSIONS: The risk of developing a tuberosity fracture during an extraction of an upper wisdom tooth increases with age by 3.1% per year. Teeth with a caries lesion or teeth with divergent or extremely curved root morphology are associated with a higher risk for tuberosity fractures. Although, distoangular teeth had reduced risk of developing a tuberosity fractures. Data collected in this study may help to evaluate the risk factors associated with tuberosity fractures, and can assist in minimizing complications during extractions.

Background: Maxillofacial fractures and craniocerebral injuries are common in patients with head trauma. These are injuries with high mortality and morbidity. Therefore, patients with head trauma should be evaluated early with a multidisciplinary approach. Aim: The association between frontal and maxillary bone fractures and concurrent craniocerebral injuries were investigated in patients presenting with head trauma in this study. The data of the patients were analyzed retrospectively. Methods and Material: Age and gender distributions were evaluated in frontal and maxillary fractures. Concomitant craniocerebral injuries were investigated. Craniocerebral injuries were grouped as pneumocephalus, extra-axial, intra-axial injuries and brain edema. Craniocerebral injuries in frontal and maxillary fractures were compared statistically. Results: Frontal bone and maxillary bone fractures were detected in 24% and 95% of the patients. Coexistence of pneumocephalus and intra-axial injuries in frontal bone fracture was statistically significant. The association of frontal posterior wall fractures with pneumocephalus and parenchymal contusion was found to be statistically significant. In addition, the association of craniocerebral injuries were evaluated and statistically significant ones were determined. Conclusion: The presence of maxillofacial fractures in patients presenting with head trauma increases mortality and morbidity. Craniocerebral injuries can be life-threatening and delay the treatment of facial fractures. Upper facial bone fractures are significantly more common in craniocerebral injuries.

OBJECTIVE: To study anterior nasal spine fractures, including the incidence, missed diagnosis rates, and relationship with shapes using computed tomography (CT). METHODS: Two hundred cases of axial CT images performed for maxillofacial trauma were reviewed. The incidence, correct, and missed diagnosis rates of anterior nasal spine fractures were studied. The relationship between the fracture and the shape of the anterior nasal spine was also analyzed. RESULTS: The rate of anterior nasal spine fractures was 22.00% (44 of 200). The diagnostic accuracy was 4.55% (2 of 44) and the missed diagnosis rate was 95.45% (42 of 44). The fracture rates of the double rod, single rod, triangle, and irregular anterior nasal spine were 33.85% (22 of 65), 32.26% (10 of 31), 12.24% (12 of 98), and 0.00% (0 of 6), respectively. The double and single rod types of anterior nasal spine were most likely to be fractured than the type of triangle (χ2 = 11.05, 6.67, P < .0167). No fracture was found in the irregular type of anterior nasal spine. CONCLUSION: Anterior nasal spine fractures are not rare and the high missed diagnostic rate results from unfamiliarity with the structure. Double and single rod types of anterior nasal spines are easy to fracture. Bony reconstruction and thin thickness of CT images are necessary for diagnosis.

AIM: The aim of the study was to characterize the maxillofacial fractures surgically treated in a Cuban hospital. MATERIALS AND METHODS: This was a descriptive and retrospective cross-sectional study based on the medical records of patients attended between January 1, 2017 and December 31, 2019 in the Maxillofacial Surgery Department of Carlos Manuel de Céspedes General University Hospital, Cuba. Age, gender, residency, municipality, etiology, month and year of trauma, number and type of fractures, and alcohol consumption at the time of trauma were recorded. RESULTS: 126 cases and 304 fractures were investigated. Males were the most affected (n = 115; 91.27%). The main etiology was interpersonal violence (IPV) (46.03%). Seventy-one (56.35%) patients had zygomatico-maxillary complex fractures. In the multivariate analysis, alcohol consumption was significantly lower as the age increased (a PR: 0.989; confidence interval [CI] 95%: 0.979-0.99; p = 0.026), as well as in those patients who lived in urban zones (a PR: 0.57; CI 95%: 0.44-0.74; p < 0.001), adjusted by the side of the fracture and the municipality. CONCLUSIONS: The profile of the maxillofacial fractures in this Cuban hospital seems to be mixed by age, affecting young people and the elderly. IPV was the major cause of maxillofacial fractures, while zygomatico-maxillary complex bones and mandible were the most affected maxillofacial areas.
OBJETIVO: Caracterizar las fracturas maxilofaciales tratadas quirúrgicamente en un hospital cubano. MATERIAL Y MÉTODOS: estudio descriptivo, retrospectivo y transversal basado en las historias clínicas de los pacientes atendidos entre el 1 de enero de 2017 y el 31 de diciembre del 2019 en el departamento de Cirugía Maxilofacial del Hospital General Universitario Carlos Manuel de Céspedes. Las variables estudiadas fueron: edad, sexo, residencia, municipio, etiología, mes y año del trauma, número y tipos de fracturas, y consumo de alcohol. RESULTADOS: Se estudiaron 126 pacientes con 304 fracturas. Los hombres fueron los más afectados (n = 115; 91.27%). La principal etiología fue la violencia interpersonal (46,03%). 71 pacientes tuvieron fracturas del complejo cigomático-maxilar. En el análisis multivariado, se encontró que el consumo de alcohol fue menor conforme aumentaba la edad (RPa: 0,989; IC 95%: 0,979-0,99; p = 0,026), así como en los pacientes que vivían en la zona urbana (RPa: 0,57; IC 95%: 0,44-0,74; p < 0,001); ajustados por el lado de la fractura y el municipio de residencia. CONCLUSIONES: El perfil de las fracturas maxilofaciales en este hospital cubano muestra afectación tanto de jóvenes como adultos.

ABSTRACT: Oral and maxillofacial fractures are the most common injuries among multiple trauma. About 5% to 10% of trauma patients having facial fractures. The objectives of this case study are to focus the most common mid-face fractures types' and to determine the relationship of the midface fracture in maxillofacial trauma among the patient who attended the outpatient clinic in a Hospital Universiti Sains Malaysia. In this research paper, an advanced statistical tool was chosen through the multilayer perceptron neural network methodology (MLPNN). Multilayer perceptron neural network methodology was applied to determine the most associated predictor important toward maxillary bone injury. Through the predictor important classification analysis, the relationship of each bone will be determined, and sorting according to their contribution. After sorting the most associated predictor important toward maxillary bone injury, the validation process will be applied through the value of training, testing, and validation. The input variables of MLPNN were zygomatic complex fracture, orbital wall fracture, nasal bone fracture, frontal bone fracture, and zygomatic arch fracture. The performance of MLPNN having high accuracy with 82.2%. As a conclusion, the zygomatic complex fracture is the most common fracture trauma among the patient, having the most important association toward maxillary bone fracture. This finding has the highest potential for further statistical modeling for education purposes and the decision-maker among the surgeon.

Understanding the cause, severity, and elapsed time for the restoration of the functions of maxillofacial injuries can contribute to the establishment of clinical priorities aiming at effective treatment and further prevention of facial trauma. The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment. We analyzed 114 medical records of patients treated at the Hospital Montenegro, who attended follow-up consultations for up to 180 days. For analysis of the recovery time, we performed survival analysis, followed by COX analysis. We observed that half of the patients recovered their functions within 20 days. The average time for recovery from trauma in the zygomatic-orbital-malar-nasal complex was 11 days, and in the maxillary-mandibular complex, 21 days (HR: 1.5 [0.99 2.3], p = 0.055). Although functional reestablishment has reached high rates after the surgical approach, it is necessary to analyze the failing cases, as well as the economic impacts and the prevention strategies associated with facial trauma, to improve the service to the population.

BACKGROUND: Most literature regarding traumatic Le Fort or maxillary fractures exists in the adult population, with limited information regarding the epidemiology and management of pediatric fractures. The purpose of this study was to evaluate fracture mechanism, surgical management, and associated injuries in pediatric patients with Le Fort fractures. METHODS: A retrospective chart analysis of all pediatric patients age ≤18 years diagnosed with facial fractures at a single level 1 trauma center over a 10-year period (January 2006-December 2015) was performed. Demographics, fracture location, mechanism of injury, and hospital course were abstracted as well as associated injuries and need for operative management. RESULTS: A total of 1274 patients met inclusion criteria. Sixty-nine (5.4%) presented with Le Fort fractures. Factors associated with Le Fort fractures included motor vehicle collisions (Pâ<â0.001), increased age (Pâ<â0.001), and traumatic brain injury (Pâ<â0.04). Patients with Le Fort fractures were more likely to need intensive care unit admission (Pâ<â0.001), surgical management (Pâ<â0.001), transfusions (Pâ<â0.001), secondary fixation surgery (Pâ<â0.001), and have a longer length of stay (Pâ<â0.001). Multivariate showed increased odds for increased age (OR 1.1; 95%CI 1.04-1.17) and concomitant orbit fractures (OR 8.33; 95%CI 4.08-19.34). Decreased odds were associated for all mechanisms of injury other than motor vehicle collisions (Other blunt trauma: OR 0.36; 95%CI 0.2-0.6. Penetrating trauma: OR 0.13; 95%CI 0.01-0.6). CONCLUSION: Maxillary or Le Fort fractures represent a small portion of pediatric facial fractures but require high rates of operative management. The high velocity required to create this fracture type is associated with significant traumatic comorbidities, which can complicate the hospital course.

BACKGROUND/PURPOSE: To retrospectively analyze the epidemiological features, clinical diagnosis, and treatment of 610 patients with maxillofacial fractures, while providing a reference for the prevention and optimized treatment of maxillofacial fractures. METHODS: Data of patients with maxillofacial fractures who were treated and followed up at the Second People's Hospital of Kashi Prefecture from June 2012 to April 2018 were summarized. The epidemiological features, clinical manifestations, fracture sites, treatment methods, and results were analyzed. RESULTS: The highest incidence was in the age range of 20 to 49 years. The main cause of fracture was traffic injury. Mandibular fractures accounted for 37.77%, zygoma and zygomatic arch fractures for 37.00%, and maxillary fractures for 21.19%. Atypical zygomatic arch fractures were more common in the maxilla, followed by Le Fort I and II fractures. Closed fractures accounted for 85.97%. Many (73.39%) patients were treated with computed tomography 3-dimensional (3D)-mediated precision modified incision internal fixation with satisfactory results. CONCLUSIONS: There is a high incidence of maxillofacial fractures among young men, especially in summer, with the most common injuries being traffic-related injuries. The most common site is the mandible, followed by the zygomatic arch, zygomatic complex, and maxilla. Computed tomography 3D-mediated precision modified incision internal fixation can achieve satisfactory results.

The frequency of midface and frontobasal fractures has increased over the past 40 years despite the improvement and stringent regulation implemented on modern safety equipment (belts, helmets ). This observation might be correlated with the progress of radiodiagnosis tools. Literature was reviewed according to Prisma guidelines. We searched for reviewed articles, published between January 2000 and December 2017, through Medline (Pubmed) online databases and ScienceDirect, using the following MeSH Keywords: "Le Fort classification", "Le Fort fracture", "Frontobasal fracture", "skull base fracture", "Midface Fractures". Among 652 patients with frontobasal fractures, 125 (19.1%) were associated with a Le Fort fracture. 59 (9%) were associated with Le Fort III fracture, 51 (7.8%) with Le Fort II fracture and 15 (2.3%) with Le Fort I fracture. When frontobasal fractures were associated with midfacial fractures, we found 18 cerebrospinal fluid leaks (11.8 %) and 19 cases of meningitis (12.5 %). When only the frontobasal area was involved, there were 6 cerebrospinal fluid leaks (4.3 %) and 6 meningitis (4.3 %). Our results highlight a regular association between Le Fort fractures and frontobasal fractures for stages II and stage III of Le Fort fractures and also found a higher rate of neuro-septic complication. Further research shall investigate treatment and monitoring recommendations fitting modern epidemiology of craniofacial traumatology.

RESUMO O entendimento da causa, da gravidade e do tempo decorrido para o restabelecimento das funções de lesões maxilofaciais pode contribuir para o estabelecimento de prioridades clínicas objetivando o efetivo tratamento e prevenção dos traumatismos de face. Assim, o objetivo deste estudo foi compreender quais os fatores associados ao restabelecimento das funções mastigatórias, oculares e nasais em vítimas de trauma de face, estimando o tempo para recuperação das funções, após o tratamento cirúrgico. Foram analisados 114 prontuários de pacientes atendidos no Hospital de Montenegro que compareceram às consultas de acompanhamento por até 180 dias. Para a análise do tempo para a recuperação, foi realizada a análise de sobrevida, seguida da análise de COX. Observou-se que metade dos pacientes recuperaram as funções em até 20 dias, sendo que o tempo médio para recuperação dos traumas no complexo zigomático-orbitário-malar-nasal foi de 11 dias e do complexo maxilo - mandibular de 21 dias (HR: 1,5 (0,99 - 2,3) p=0,055). Embora o restabelecimento das funções tenha atingido taxas elevadas após abordagem cirúrgicas, faz-se necessária a análise dos casos de insucessos bem como os impactos econômicos e as estratégias de prevenção associados aos traumas de face a fim de qualificar o serviço prestado à população.

Importance: The nasal bone is one of the most commonly fractured bones of the midface. However, the frequency of coincident fractures of adjacent bones such as the frontal process of the maxillary bone, nasal septum, and medial or inferior orbital walls has not been fully evaluated. Objective: The purpose of this study was to investigate the incidence of fractures of adjacent structures in the setting of a nasal bone fracture. Second, we propose a new classification system of nasal bone fractures with involvement of adjacent bony structures. Design, Setting, and Participants: One thousand, one hundred ninety-three patients with midfacial fractures were retrospectively reviewed. The characteristics of fractures of the nasal bone and the incidence of coincident fractures of the frontal process of maxilla, bony nasal septum, medial, or inferior orbital walls were analyzed. Exposure: All patients included in the study presented with nasal trauma. Main Outcomes and Measures: The coincident fractures of adjacent midfacial structures were assessed, and a new classification of midfacial fractures based on computed tomography (CT) scan images was proposed. Results: Among the 1193 cases, bilateral fractures of the nasal bone were most common (69.24%), and coexistent fracture of the frontal process of the maxilla and bony nasal septum was 66.89% and 42.25%, respectively. Coincident fracture of the orbital walls was observed in 16.51% of cases. The major etiology of fracture for the younger and elderly groups was falls, compared with assault as the most common etiology in the adult group. A classification scheme was generated in which fractures of the nasal bone were divided into five types depending on coexisting fractures of adjacent structures. Conclusions and Relevance: External force applied to the nasal bone can also lead to coexistent fracture of adjacent bony structures including the frontal process of the maxilla, nasal septum, and orbital walls. The proposed classification of nasal fracture based on CT imaging helps to incorporate coincident disruption of adjacent structures.

BACKGROUND/AIM: Epidemiology of maxillofacial fractures (MFF) varies between populations. This study investigated the epidemiology of MFF treated at the Oral and Maxillofacial Surgery (OMFS) Unit, Hospital Universiti Sains Malaysia (USM). METHODS: A retrospective review of 473 medical records of patients with MFF treated from June 2013 to December 2015 was conducted. Information on demographic characteristics of patients, aetiology of injury, types of MFF, and treatment was obtained. Descriptive analysis, Pearson's chi-squared test, and multiple logistic regression analysis were conducted. The level of significance was set at 0.05. RESULTS: Most patients treated for MFF were males (82.2%), aged 30 and below (63.1%), and from Malay ethnic (97.4%). Road traffic accident was the most common cause of MFF (83.1%), with motorcycle accident accounting for most injuries (73.6%). Orbital wall fracture was the most frequent MFF type (51.2%). About half of MFF patients (51.4%) were treated conservatively. Patients aged more than 20 years old were at higher odds of sustaining orbital wall fracture (AOR= 1.76; 95% CI: 1.214-2.558; P= 0.003) but were at lower odds of sustaining mandibular fracture (AOR= 0.47; 95% CI: 0.315-0.695; P= 0.001) than patients who are 20 years old and younger. Helmet use among motorcyclists was significantly associated with the nasal, orbital wall, and maxillary sinus wall fractures (P= 0.006, 0.010, and 0.004, respectively). CONCLUSION: Motorcycle accident was the most common cause of MFF in Kelantan, Malaysia. Ages of patient and helmet use were associated with the type of MFF sustained. This study provides important information to facilitate the planning of MFF prevention strategies among motorcyclists and emphasizes the importance of using a helmet when riding a motorcycle.

OBJECTIVES: The aim of this retrospective study was to describe the location and distribution of craniomaxillofacial (CMF) fractures in 45 cats presented to a veterinary referral centre between 2012 and 2017. METHODS: Cats with a history of head trauma, one or more CMF fractures and a pretreatment CT scan of the CMF region were included in this study. For the purpose of the study, the CMF skeleton was divided into 15 functional anatomical regions and the fracture sites were allocated to one of these functional regions. Statistical analysis was performed using R. RESULTS: Skull fractures were evident in 80.0% of cats, and mandibular fractures in 86.7% of cats in this study. The median number of anatomical functional regions affected was eight and there was evidence of moderate or strong correlation between fractures of different regions of the mid-face. Where fractures were recorded in the nasopharynx and orbit they were bilateral in 93.5% and 89.7%, respectively. Twenty-six (57.8%) of the cats had fractures affecting one or both temporomandibular joints, which included fractures of the mandibular fossa, condylar neck and condyle. Twenty-nine cats (64.4%) had tooth fractures and seven cats (15.6%) had significant eye injuries. CONCLUSIONS AND RELEVANCE: Cats presenting with a single symphyseal separation or parasymphyseal fracture are very likely to have further fractures at other locations. Fractures in the nasopharynx, orbit, nose, upper jaw, intermaxillary suture and zygomatic arch regions (the 'mid-face') are likely to occur together. The pattern of distribution of mandibular fractures is not as predictable as that for maxillary fractures. CT imaging is required to achieve a complete diagnosis of the location and distribution of skull fractures in cats after head trauma.

INTRODUCTION: Midfacial fractures are extremely important oral and maxillofacial problems because they take varied forms and are frequently accompanied by major long-term esthetic or functional complications. Their etiology and epidemiology vary significantly in the literature, and the main causes are varied by population. The aim of this study is to identify the main traumatic etiology of midfacial fractures, along with the main categories of affected patients in our geographical area, in order to establish the need for measures that can prevent fractures in the future. MATERIALS AND METHODS: We conducted a retrospective study over a 10-year period in 379 patients. Data were extracted from the patients' charts, and the following variables were taken into consideration: sex, age, environment of origin, education level, and traumatic etiology. RESULTS: Midfacial fractures most frequently affected the 20-29 years age group (31.93%), male sex (n = 333, 87.86%, M:F = 7.23:1), patients from urban areas (n = 206, 54.35%), and patients without education (46.70%). The most frequent etiology was interpersonal violence (44.85%), followed by fall trauma (16.62%) and road traffic accidents (15.30%). Statistical correlations evidenced that urban environment favors midfacial fractures caused by interpersonal violence and road traffic accidents or sports injuries, while in rural areas, domestic accidents and animal attacks are predominant (P = 0.000). CONCLUSIONS: The overwhelming incidence of interpersonal violence in our population is currently a major public health problem. Implementing laws and initiating national programs for the prevention of interpersonal violence would lead to a considerable reduction of midfacial fractures in the Western Romanian population.

BACKGROUND: This study aims to describe the major pterygoid plate fractures (PPFs) patterns unrelated to Le Fort fractures (LFFs) using maxillofacial computed tomography (CT). METHODS: After obtaining our hospital ethics committee approval (37-05), data for PPF were acquired from the medical records of all the trauma patients who were diagnosed using CT at our hospital from April 2014 to April 2017. RESULTS: Of the 178 patients, 135 (male/female = 86/49; mean age = 37.2 years) had LFF and 43 (male/female = 35/8; mean age = 38.6 years) had PPF without associated LFF. PPF patterns unrelated to LFF included temporal bone (11.6%), sphenotemporal buttress (25.5%), zygomaticomaxillary complex (30.2%), displaced mandible (23.3%), nasal (4.7%), and isolated fractures (4.7%). The etiologies of facial fractures were not significantly different between both sexes (p=0.576). No significant difference between Le Fort and non-Le Fort groups was found for age (p=0.603) and the causes of trauma (p=0.183). CONCLUSION: PPF is most commonly seen with LFF, but it may also be seen alone or with other non-LFF indicating that all PPF are not related to LFF. Axial reformatted CT images can easily display PPF and the degree of displacement of the fragments, and they can be used to guide surgical reduction of the fractures.
