Maxillofacial Fractures in Pondicherry, India: An Eight?Year Single Centre Retrospective Study

Background: The purpose of the present study was to analyze the etiology, incidence, pattern, and treatment modalities of patients with maxillofacial fractures treated at the Department of Dentistry of a medical college in Pondicherry during the period between June 2011 and June 2019. Materials and Methods: A retrospective epidemiological study of 277 patients treated for maxillofacial fractures between June 2011 and June 2019 was performed. Data regarding age, gender, etiology, site of the fracture, time of injury, presence of associated injuries, treatment modalities, and complications were recorded. Results: A total of 491 maxillofacial fractures were seen in 277 patients. These were 261 males (94.2%) and 16 females (5.8%) with a male to female ratio of 16.3:1. Most of the patients 79.8% were in the age group of 11 to 40 years. Most common cause of injury was Road Traffic Collisions (RTCs; 62.1%), followed by fall (20.2%), assault (14.4%) and others (3.3%). Fractures of the mandible (52.3%) and zygomatic complex (18.9%) were the most common maxillofacial fractures reported in our study. 196 patients sustained associated injuries with a prevalence of soft tissue injury (61.2%). Majority of fractures were treated with open reduction and internal fixation (ORIF; 71.9%) of patients followed by closed reduction (17.7%) and observation only (10.4%). Postoperative complications were presented in 16.8% of the patients in the study. Conclusion: RTC is the commonest cause of maxillofacial injury with a male predominance in our study. Mandibular and zygomatic complex fractures were the most common. ORIF remains the preferred method of treatment.

Management of isolated mandibular body fractures in adults

Objective@#The mandible is the most common fractured craniofacial bone of all craniofacial fractures in the Philippines, with the mandibular body as the most involved segment of all mandibular fractures. To the best of our knowledge, there are no existing guidelines for the diagnosis and management of mandibular body fractures in particular. General guidelines include the American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAOHNSF) Resident Manual of Trauma to the Face, Head, and Neck chapter on Mandibular Trauma, the American Association of Oral and Maxillofacial Surgeons (AAOMS) Clinical Practice Guidelines for Oral and Maxillofacial Surgery section on the Mandibular Angle, Body, and Ramus, and a 2013 Cochrane Systematic Review on interventions for the management of mandibular fractures. On the other hand, a very specific Clinical Practice Guideline on the Management of Unilateral Condylar Fracture of the Mandible was published by the Ministry of Health Malaysia in 2005. Addressing the prevalence of mandibular body fractures, and dearth of specific guidelines for its diagnosis and management, this clinical practice guideline focuses on the management of isolated mandibular body fractures in adults.@*Purpose@#This guideline is meant for all clinicians (otolaryngologists – head and neck surgeons, as well as primary care and specialist physicians, nurses and nurse practitioners, midwives and community health workers, dentists, and emergency first-responders) who may provide care to adults aged 18 years and above that may present with an acute history and physical and/or laboratory examination findings that may lead to a diagnosis of isolated mandibular body fracture and its subsequent medical and surgical management, including health promotion and disease prevention. It is applicable in any setting (including urban and rural primary-care, community centers, treatment units, hospital emergency rooms, operating rooms) in which adults with isolated mandibular body fractures would be identified, diagnosed, or managed. Outcomes are functional resolution of isolated mandibular body fractures; achieving premorbid form; avoiding use of context-inappropriate diagnostics and therapeutics; minimizing use of ineffective interventions; avoiding co-morbid infections, conditions, complications and adverse events; minimizing cost; maximizing health-related quality of life of individuals with isolated mandibular body fracture; increasing patient satisfaction; and preventing recurrence in patients and occurrence in others.@*Action Statements@#The guideline development group made strong recommendationsfor the following key action statements: (6) pain management- clinicians should routinely evaluate pain in patients with isolated mandibular body fractures using a numerical rating scale (NRS) or visual analog scale (VAS); analgesics should be routinely offered to patients with a numerical rating pain scale score or VAS of at least 4/10 (paracetamol and a mild opioid with or without an adjuvant analgesic) until the numerical rating pain scale score or VAS is 3/10 at most; (7) antibiotics- prophylactic antibiotics should be given to adult patients with isolated mandibular body fractures with concomitant mucosal or skin opening with or without direct visualization of bone fragments; penicillin is the drug of choice while clindamycin may be used as an alternative; and (14) prevention- clinicians should advocate for compliance with road traffic safety laws (speed limit, anti-drunk driving, seatbelt and helmet use) for the prevention of motor vehicle, cycling and pedestrian accidents and maxillofacial injuries.The guideline development group made recommendations for the following key action statements: (1) history, clinical presentation, and diagnosis - clinicians should consider a presumptive diagnosis of mandibular fracture in adults presenting with a history of traumatic injury to the jaw plus a positive tongue blade test, and any of the following: malocclusion, trismus, tenderness on jaw closure and broken tooth; (2) panoramic x-ray - clinicians may request for panoramic x-ray as the initial imaging tool in evaluating patients with a presumptive clinical diagnosis; (3) radiographs - where panoramic radiography is not available, clinicians may recommend plain mandibular radiography; (4) computed tomography - if available, non-contrast facial CT Scan may be obtained; (5) immobilization - fractures should be temporarily immobilized/splinted with a figure-of-eight bandage until definitive surgical management can be performed or while initiating transport during emergency situations; (8) anesthesia - nasotracheal intubation is the preferred route of anesthesia; in the presence of contraindications, submental intubation or tracheostomy may be performed; (9) observation - with a soft diet may serve as management for favorable isolated nondisplaced and nonmobile mandibular body fractures with unchanged pre - traumatic occlusion; (10) closed reduction - with immobilization by maxillomandibular fixation for 4-6 weeks may be considered for minimally displaced favorable isolated mandibular body fractures with stable dentition, good nutrition and willingness to comply with post-procedure care that may affect oral hygiene, diet modifications, appearance, oral health and functional concerns (eating, swallowing and speech); (11) open reduction with transosseous wiring - with MMF is an option for isolated displaced unfavorable and unstable mandibular body fracture patients who cannot afford or avail of titanium plates; (12) open reduction with titanium plates - ORIF using titanium plates and screws should be performed in isolated displaced unfavorable and unstable mandibular body fracture; (13) maxillomandibular fixation - intraoperative MMF may not be routinely needed prior to reduction and internal fixation; and (15) promotion - clinicians should play a positive role in the prevention of interpersonal and collective violence as well as the settings in which violence occurs in order to avoid injuries in general and mandibular fractures in particular.

A study of pattern of maxillofacial fractures and its complications

Background: Incidence of maxillofacial fractures is quite high worldwide. A very important aesthetic function is served by maxillofacial skeleton moreover the prominent position of maxillofacial skeleton makes it more susceptible to fracture.Methods: A prospective study was done to assess the main etiology and pattern of maxillofacial fractures of 60 patients who came to the emergency department of Sri Guru Ram Das Institute of Medical sciences and Research between January 2018 and June 2019.Results: Total number of patients taken for this study were 60. The number of male patients were 56 (93.33%) and number of female patients were 4 (6.66%) and male to female ratio was (14:1). The age range spanned from 11 years to 70 years with (mean age=37.30 years, SD=14.27). Primary etiologic factor for maxillofacial fractures was road traffic accidents (49, 81.66%), followed by fall (8, 13.33%), and assault accounted for (3, 5%). Total 229 fractures were present in 60 patients. Concerning the anatomical site of fractures, it was explored that most common site of fractures is orbit (59, 25.72%) followed by fractures of maxilla (55, 24%) and zygomatic complex (35, 15.28%). Infection was most common complication and was present in 2 (3.33%) of the patients during hospital stay. 21 (35%) of the patients had associated head injury and maximum patients 49 (81.66%) were treated by open reduction and internal fixation.Conclusions: It is concluded, that main etiology of maxillofacial trauma is road side accidents. Therefore, strict compliance of traffic rules can avoid such injuries.

Use of neuron-specific enolase to predict mild brain injury in motorcycle crash patients with maxillofacial fractures: A pilot study / 中华创伤杂志(英文版)

PURPOSE@#Mild traumatic brain injury (TBI) is common but accurate diagnosis and its clinical consequences have been a problem. Maxillofacial trauma does have an association with TBI. Neuron-specific enolase (NSE) has been developed to evaluate neuronal damage. The objective of this study was to investigate the accuracy of NSE serum levels to detect mild brain injury of patients with sustained maxillofacial fractures during motor vehicle accidents.@*METHODS@#Blood samples were drawn from 40 healthy people (control group) and 48 trauma patients who had sustained isolated maxillofacial fractures and mild brain injury in motor vehicle accidents. Brain injuries were graded by Glasgow Coma Scale. In the trauma group, correlations between the NSE serum value and different facial fracture sites were also assessed.@*RESULTS@#The NSE serum level (mean ± SD, ng/ml) in the 48 patients with maxillofacial fractures and mild TBI was 13.12 ± 9.68, significantly higher than that measured in the healthy control group (7.72 ± 1.82, p < 0.001). The mean NSE serum level (ng/ml) in the lower part of the facial skeleton (15.44 with SD 15.34) was higher than that in the upper facial part (12.42 with SD 7.68); and the mean NSE level (ng/ml) in the middle-and lower part (11.97 with SD 5.63) was higher than in the middle part (7.88 with SD 2.64).@*CONCLUSION@#An increase in NSE serum levels can be observed in patients sustained maxillofacial fractures and mild brain injury.

More than 50% of patients with these injuries have multisystem trauma that requires coordinated management between emergency physicians and surgical specialists in oral and maxillofacial surgery, otolaryngology, plastic surgery, ophthalmology, and trauma surgery. The aim of this study is to identify the patterns of brain injuries associated with maxillofacial trauma and its outcome.</p><p><b>METHODS</b>This descriptive study (cross-sectional) was carried out among 90 polytrauma patients with maxillofacial fractures attending the Emergency Department at Suez Canal university Hospital and fulfilling our inclusion and exclusion criteria.</p><p><b>RESULTS</b>This study demonstrates the relation between type of maxillofacial fracture and type of traumatic brain injuries in which the majority of patients with epidural hemorrhage presented with mid face fractures (60%), while the minority of them presented with upper and lower face fractures (20% for each of them). The majority of patients with subdural hemorrhage were associated with mid face fractures (75%), the majority of patients with brain contusions associated with mid face fractures (75%), and all of the patients presented by pneumocephalus were associated with mid face fractures (100%).</p><p><b>CONCLUSION</b>The results of this study confirm the value of quick diagnosis and early intervention, which is fundamental to prevent morbidity as well as mortality especially with regards to prevention of traumatic brain injury as even a short duration of hypoxia and edema will lead to significant permanent neurological deficits.</p>

Emergence of maxillofacial surgery service: profile changes 1998 and 2012.

Background: The face is more prone to trauma, being the most exposed part of the body. Over the last three decades, there has been a growing increase of trauma. Objectives: This research aims to identify the kinds of assistance and the profiles of the assisted between 1998 and 2012 at the maxillofacial surgery service at Odilon Behrens Hospital. Methods: A retrospective and descriptive study was conducted at Odilon Behrens Municipal Hospital in Belo Horizonte, Minas Gerais, based on reports at appointments completed by the maxillofacial surgery team, using survey data from a total of 2,920 patients registered for control. The assessment took into account treatments performed in 1998 compared to 2012. The data analysed essentially included diagnosis and hands-on management in our service. Results: After evaluation, the results obtained showed an increase in cases from 1998 to 2012 due to aetiologies such as: fall from height, orofacial pain, motorcycle accidents, odontogenic infections, accident with objects, oedema, epistaxis and household accidents; in contrast, a significant reduction in cases between 1998 and 2012 was observed in the following aetiologies: cycling accident, automobile accident, facial trauma, pedestrian injury from vehicles, accident involving animals Conclusion: Our research indicates that the ratio of 2:1 male/female patients in 1998, decreased to 55:1 in 2012. Although there were slight variation sin aetiology and diagnoses, in general our results remain the same when comparing 1998 to 2012.

Introdução: O trauma é um dos principais problemas de saúde pública em todos os países, sendo os que acometem a região facial muito frequentes. O presente trabalho objetiva avaliar dados epidemiológicos de pacientes que sofreram trauma de face com fratura. Métodos: Estudo epidemiológico realizado por meio dos prontuários de 92 pacientes. Foram selecionados indivíduos com trauma facial de qualquer intensidade, no período de janeiro de 2009 a janeiro de 2013, e agrupados de acordo com a etiologia e a localização das fraturas. Os dados coletados foram apresentados em valores absolutos e porcentagens. Resultados: Houve prevalência de pacientes do sexo masculino. A etiologia do trauma de face mais encontrada foi a violência interpessoal, observada na maioria dos grupos, exceto naquele acima de 45 anos, cuja predominância etiológica foi de queda e acidente de automóvel. A incidência das causas variou de acordo com a faixa etária: < 18 anos, de 19 a 25 anos, de 26 a 35 anos, de 36 a 45 anos e > 45 anos. Setenta e cinco por cento das fraturas de mandíbula foram unilaterais e 25%, bilaterais. O tratamento cirúrgico de fixação com placas foi o mais utilizado. No nosso estudo, catorze pacientes apresentaram complicação pós-cirúrgica. Conclusão: Há necessidade de um atendimento sistematizado para os traumas faciais. A variação na faixa etária encontrada entre os pacientes estudados demonstra que o trauma facial abrange indivíduos em qualquer idade, embora seja maior entre os jovens. Acreditamos que o presente estudo epidemiológico possibilitará a melhora da qualidade no atendimento aos pacientes com trauma facial.

Introduction: Trauma is a major public health problem in all countries, and injuries involving the facial region are very common. This study aims to assess the epidemiological data of patients who suffered facial trauma with fracture. Methods: Epidemiological study conducted on 92 patient records. Individuals with facial trauma of any intensity presenting between January 2009 and January 2013 were selected and grouped according to the etiology and location of fractures. Data were presented as absolute values and percentages. Results: There was a higher prevalence of male patients. The most frequent cause of facial trauma was interpersonal violence in most groups, except for those over 45 years old, for whom the predominant causes were falls and car accidents. The frequency of the causes varied according to age: <18 years, 19-25 years old, 26-35 years old, 36-45 years and> 45 years. Seventy-five percent of mandibular fractures were unilateral and 25% bilateral. Surgical fixation with plates was the most common treatment. In our study, fourteen patients had postoperative complications. Conclusion: There is a need for systemized care for facial trauma. The variation in the age range found among the studied patients demonstrates that facial trauma includes individuals of any age, although it is more common among young people. We believe that this epidemiological study will enable the improvement of the quality of care for patients with facial trauma.

Comportamiento de las fracturas maxilofaciales atendidas en el Hospital Universitario de Maabar, República de Yemen / Behavior of the maxillofacial fractures in the Maabar's University Hospital, Yemen Republic

Introducción: las fracturas maxilofaciales constituyen más del 50 porciento del total de fracturas, y en muchas ocasiones están asociadas a otras fracturas del cuerpo humano. Objetivos: estudiar el comportamiento de estas lesiones en el Hospital Universitario de Maabar, de la Universidad de Thamar (Yemen), determinar su relación con la edad, sexo, etiología y localización, y compararlo con los resultados de otros estudios realizados en Cuba y en otros países. Métodos: se realizó un estudio estadístico descriptivo retrospectivo de las fracturas maxilofaciales atendidas por la brigada de profesores cubanos en este hospital entre los años 2006 y 2009. Las variables estudiadas fueron: sexo, edad, causa de la fractura y región afectada, así como el tipo de fractura y los traumatismos asociados. Resultados: el sexo masculino fue mucho más afectado que el femenino. Los accidentes del tránsito fueron la causa más común (más del 50 por ciento de los casos). La fractura nasal fue la más frecuente, y en más de 150 casos se detectaron traumatismos asociados, muchos muy graves, como fracturas de cráneo, de miembros y heridas de partes blandas. Conclusiones: se confirman los resultados que el sexo masculino es el más afectado, y que los accidentes del tránsito son la principal causa de fracturas en la cara. La fractura nasal es la más frecuente de todas las de los huesos faciales (más del 50 por ciento de los casos), pero otros registran la mandíbula o la región zigomática como la zona más frecuente. Impresionaron las fracturas mandibulares en niños, lo cual no es frecuente en Cuba(AU)

Introduction: the maxillofacial fractures account for more than the 50 percent of the total of fractures and often are associated with other fractures of the human body. Objectives: to study the behavior of these lesions in patients from the Maabar's University Hospital of the Thamar's University (Yemen), to determine its relation to age, sex, etiology and location and to compare it with the results of other studies conducted in Cuba and other countries. Methods: a retrospective, descriptive and statistic study was conducted on the maxillofacial fractures seen by the Cuban professor brigade in this hospital between 2006 and 2009. The study variables were: sex, age, cause of the fracture and involved region, as well as the type of fracture and associated traumata. Results: the male sex was more involved that the female one. The road accidents were the commonest cause (more than the 50 percent of cases). The nose fracture was the more frequent and in more than of 150 cases there were associated traumata much of them very severe including skull fracture, of extremities and soft tissue wounds. Conclusions: the results confirm that the male sex is the more involved one and that the road accidents are the leading cause of face fractures. The nose fracture is the more frequent of all that of facial bones (more than 50 percent of cases), but others register the mandible or the zygomatic region as the more frequent involved zone. The mandibular fractures were impressive in children, something not frequent in Cuba(AU)

Introduction. Maxillofacial trauma (MFT) is a common reason for attendance at Emergency Departments. The complex anatomy of the facial bones requires multiplanar imaging techniques for a proper evaluation. Objectives. To describe frequency and types of fractures in a series of patients with MFT evaluated by multi-slice computed tomography (MDCT) with multiplanar and 3D reconstructions. Materials and Methods. Facial bone CTs ordered for MFT by the Emergency Department from June 2008 to December 2009 were retrospectively reviewed. The following data were obtained: age, gender, cause of trauma, presence and type of fractures. Patients were evaluated with an 8-channel MDCT. Multiplanar reconstructions were performed in all cases using high resolution bone window and soft tissue window, as well as 3D reconstructions. Results. One-hundred and thirty-seven CTs were performed for MFT: 78 (57%) showed 131 fractures. Of these 78 patients, 52 (66%) were males and 26 (34%) were females; mean age 33 years old (range: 14-90 yrs.). Causes: 58 % were injuries from traffic accidents; 24% were injuries from fights; 13% were sport injuries; and 7% were due to miscellaneous etiologies. Type and frequency of fractures: 18.3% were orbital floor fractures, 16% were maxillary sinus fractures, 15.3% were nasal fractures, 13% were jaw fractures, 9.2% were orbital fractures, and 12.3% were fractures of the zygomatic-malar complex; two cases of Le Fort II-III fractures were also observed. Conclusions. Fractures were more common in males, in the age range from 15 to 35 years old. Most fractures, and the most complex ones, were caused by traffic accidents. The most common fracture, either isolated or associated with other fractures, was the orbital floor fracture.

Avaliação de traumatismos faciais por acidentes motociclísticos em Aracaju/SE / Evaluation of facial injuries from motorcycle accidents in Aracaju/SE

Diversos fatores podem estar relacionados à etiologia dos acidentes motociclísticos, destacando-se as características sócio-culturais da população estudada. Assim, foi desenvolvida uma pesquisa prospectiva, transversal e observacional com a finalidade de analisar estes traumatismos no Hospital de Urgência de Sergipe (HUSE), no período de 2008 a 2009. O estudo incluiu 145 pacientes, investigando-se dados pessoais, etiologia do acidente e regiões faciais e corporais acometidas. Houve prevalência de acidentados do gênero masculino (87,6 por cento), da cor parda (71,7 por cento) e na faixa etária de 21 a 30 anos (46,2 por cento). O maior número de acidentes ocorreu à noite e com o tempo seco (73,1 por cento) devido a desequilíbrio (78,6 por cento). Dentre as lesões de tecido mole, houve uma predominância da laceração (72,4 por cento). Os traumas dento-alveolares foram observados em 16,6 por cento dos pacientes e as fraturas, em 25,5 por cento dos acidentados. Foi observado que um grande número de pacientes não utilizava capacete, estava alcoolizado e sem habilitação específica para pilotar motocicleta. Isso evidencia a necessidade de uma maior atenção à educação dos condutores, melhor fiscalização e aplicação das leis de trânsito aos motociclistas e maior exposição pública das consequências desses acidentes, visando à redução da quantidade e intensidade de lesões corporais decorrentes desse meio de transporte.

Several factors may be related to the etiology of motorcycle accidents, especially the socio-cultural characteristics of the population studied. Thus, a prospective, cross-sectional and observational study was conducted in order to analyze injuries from motorcycle accidents in the Hospital de Urgência de Sergipe (HUSE) in the years 2008 and 2009. The study comprised 145 patients, information being collected on personal data, cause of accident and facial and other body regions affected. There was a prevalence of males (87.6 percent), dark-skinned individuals (71.7 percent) and ages ranging from 21 to 30 years (46.2 percent). The majority of accidents occurred at night in dry weather (73.1 percent), due to loss of balance (78.6 percent). Among the injuries of soft tissue, there was a predominance of lacerations (72.4 percent). Dento-alveolar injuries were observed in 16.6 percent of the patients and fractures in 25.5 percent of the injured patients. It was observed that a large number of patients had not been wearing a helmet, were drunk and without a license for riding a motorcycle. These data highlight the need for greater attention to the education of riders, better monitoring and enforcement of traffic laws and greater public exposure of the consequences of accidents in order to reduce the quantity and severity of injuries resulting from this means of transport.

Computer-aided surgical simulation and navigation in reconstruction of old maxillofacial fractures / 上海交通大学学报（医学版）

Objective To apply the three-dimensional pre-operative simulation and intra-operative real-time navigation in the reconstruction of old maxillofacial fractures so as to increase the surgical precision. Methods Six patients with old maxillofacial fractures were enrolled, and the diagnosis of unilateral old maxillofacial fractures was confirmed by clinical and imaging examinations. Virtual three-dimensional skull models were reconstructed from pre-operative CT images. The fractured bone was moved or rotated, and was reposed in a desired site according to the mirrored part from the healthy side. After patient-to-image registration, the surgical instruments and patients were tracked in real-time by optical tracking system during operation, and in this way the maxillofacial fractures were reposed satisfactorily guided by the virtual image. Results Three-dimensional simulation before operation and real-time navigation of patients and instruments during operation were realized. The error of registration was less than 1 mm. The post-operative CT examinations of these six patients revealed that the fracture reposition was same to the pre-operative planning, and the difference between them was less than 1.5 mm. The operations were minimally-invasive, with no complications. Conclusion Computer-aided surgical simulation and navigation system can effectively increase the surgical precision of reconstruction of old maxillofacial fractures.

Oral maxillofacial fractures seen at a ugandan tertiary hospital: a six-month prospective study

AIM: To investigate the epidemiological characteristics of maxillofacial fractures and associated fractures in patients seen in the Oral Surgery Unit of Mulago Hospital, Kampala, Uganda. METHODOLOGY: A six-month prospective study was conducted. Data collected included socio-demographic factors, type and etiology of injury, additional fractures, and post-surgery complications. RESULTS: One hundred thirty-two (132) cases ranging from 5-70 yrs of age were reported, with a male: female ratio of 7.7:1. The 21-30 yr age group was the largest, comprising 51.51 percent of cases (n=68). Road traffic accidents contributed to 56.06 percent (n=74) of fractures. In total, 66 percent of the sample (n=87) suffered isolated mandibular fractures. Symphyseal and maxillary fractures were the most common mandibular and mid-facial fractures, respectively. Among associated fractures, the femur was most affected. A total of 39 (29.54 percent) of patients had post-operative complications, of which infection accounted for 48.71 percent (n= 19), and malocclusion accounted for 17.94 percent (n=7). CONCLUSIONS: Anticipated changes in maxillofacial trauma trends necessitate regular epidemiologic studies of facial fractures to allow for development and implementation of timely novel preventive measures.

A retrospective study of 101 maxillofacial fractures / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the clinical characters and treatments of maxillofacial fractures. Method: A review of 101 maxillofacial fractures was presented with respect to age, sex, cause of fractures, pattern of fractures, treatments and therapeutic effect. Result:The majority of fractures were found in 20-to-50-years-old males. Most fractures happened in summer and the leading causes were traffic accidents. Mandible was the most part of fractures and associated combined injures were found in 31 cases. Rigid internal fixation was the primary treatment. Conclusion:Maxillofacial factures mainly occurred in young adult males and traffic accidents were the main causes. Rigid internal fixation after exact replacement was the primary common treatment.

Etiology and Patterns of Maxillofacial Fractures in 518 patients in Korea

PURPOSE: Different patterns in the causes of maxillofacial injury are thought to correlate with socioeconomic status and regional environment. This study investigated maxillofacial fractures in order to analyze maxillofacial trauma characteristics and the relationship between the causes and injury patterns in Korea. MATERIAL AND METHODS: A total of 518 patients with maxillofacial fractures who were treated at the Seoul National University Boramae Hospital between 1996 and 2004 were retrospectively analyzed. Data were obtained from the patients' medical records and radiographs. The male to female ratio in the patient group was 2.78:1, and the mean age was 32.3 years. RESULTS: Midfacial fractures were the most common location of injury (46.1%). The most common etiologic factor was an activity associated with daily life (42.6%) including falls, stumbling, and collisions. The second most common cause was assault (32.4%), followed by traffic accidents (13.7%). In the case of midfacial fractures and mandibular fractures, assault was the most common etiologic factor, whereas in the case of alveolar bone fractures, activities associated with daily life were the most common cause. With regard to age groups, assault was the most common cause for patients between 10 and 39 years old and an activity associated with daily life was the most common cause in those under 10 years and over 40 years. CONCLUSIONS: This study concluded that activities associated with daily life and assault causes a large proportion of Korean maxillofacial injuries and that preventive measures should be implemented in order to minimize these risks.
