Incidence and aetiology of facial injuries resulting from motor vehicle accidents in Queensland for a three-year period

World Oral and Maxillofacial Trauma (WORMAT) project: A multicenter prospective analysis of epidemiology and patterns of maxillofacial trauma around the world

BACKGROUND/AIM

The World Oral Maxillofacial Trauma (WORMAT) project was performed to analyze the causes and characteristics of maxillofacial fractures managed in 14 maxillofacial surgery divisions over a 1-year period.

METHODS

The following data were collected: age, sex, cause and mechanism of maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score (FISS), associated injury, day of trauma, timing and type of treatment, and length of hospitalization. Statistical analyses were performed using SPSS software.

RESULTS

Between 30 September 2019 and 4 October 2020, 2,387 patients (1,825 males and 562 females [ratio 3.2:1], 47.6% aged 20-39 years [mean age 37.2 years, median 33.0 years]) were hospitalised. The main cause of maxillofacial fracture was road traffic accidents (RTA), which were statistically associated with male adults as like as assault, sport, and work (p<0,05). Half of the fractures involved the middle third of the face, statistically associated with fall and assault (p<0.05). Trauma in multiple locations was significantly associated with longer hospital stay (p<0.05). The mean length of hospitalization was 3.9 days (95% Confidence Interval 3.7-4.2).

CONCLUSIONS

This prospective, multicenter epidemiological study confirmed that young adult males were the ones most commonly affected by maxillofacial fracture. RTAs and assaults are statistically associated with the adult population, while falls are associated with females and older population.

Patterns of Maxillofacial Injuries in the Middle East and North Africa: A Systematic Review

OBJECTIVE

The objective of this review was to investigate the epidemiological characteristics of maxillofacial fractures (MFFs), to establish the prevalence of MFFs, and to recognise the major causative factors in both males and females in the Middle East and North Africa (MENA) region.

STUDY DESIGN

The protocol of this systematic reviews was established according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P); the following databases were searched: PubMed/Medline, Scopus, Google Scholar and Web of Science. We used STROBE checklist to assess the risk of bias in all identified studies, 37 studies fulfilled the eligibility criteria, and hence were selected for analysis.

RESULTS

A total of 27,994 patients (22,965 males and 5,129 females) ranging from 0 to 97 years who experienced maxillofacial injuries during the study period were entered into this review. Road traffic accidents (RTAs) were the most common cause of MFF followed by falls. The mandible was the most common site of injury. In the MENA region, males outnumbered females in terms of maxillofacial injuries with a ratio of 4.5:1.

CONCLUSION

Maxillofacial fractures are highly prevalent in the MENA region, and they are mainly caused by RTAs, especially among young males. Therefore, the concerned authorities need to employ and implement stricter traffic rules in order to minimise the risk of maxillofacial injuries and their subsequent increased morbidity and mortality rates.

An in-depth technical and medical investigation of facial injuries caused by car accidents

BACKGROUND

Many studies have investigated the issue of facial injuries caused by car accidents, but only a few have addressed the technical and clinical aspects of such accidents and injuries in depth. The aim of this study was to identify risk factors and protective elements for facial injuries in car accidents.

METHODS

We analysed the technical and clinical data of patients with facial injuries caused by car accidents over a 16-year period (2000-2016) and investigated the following factors: sitting position, sex, age, accident time, use of a seatbelt, deployment of the front airbag, direction of impact, speed at the time of collision, and occurrence and location of facial injuries.

RESULTS

Of the 1291 patients involved in car accidents who were included in our study, 291 (22.5%) had suffered facial injuries. We found a significant association between occurrence of facial injuries and sex, speed at the time of collision, impact from the back, seatbelt usage, and deployment of the front airbag. In accidents occurring at speeds over 40 km/h, automobile security measures had no significant influence on the occurrence of facial injuries in drivers and front-seat passengers. In accidents occurring at speeds between 0 and 20 km/h, seatbelt usage (without airbag deployment) solely showed a significant protective influence against the occurrence of facial injuries (odd ratio [OR], 0.130; confidence interval [CI], 0.038-0.451). In contrast, patients who were in accidents at speeds between 21 and 40 km/h suffered significantly fewer facial injuries when wearing a seatbelt with the front airbag being deployed (OR, 0.245; CI, 0.091-0.665) or undeployed (OR, 0.216; CI, 0.084-0.561).

CONCLUSION

Male sex and a high speed at the time of collision are significant risk factors for the occurrence of facial injuries. The security measurements evaluated in this study only exerted a protective influence at low speeds (below 40 km/h). This indicates a possible weakness of these security systems with regard to preventing facial injuries. Engineers could benefit from these findings and improve the efficiency of existing security measures and eventually help decrease the incidence of facial injuries.

Analysis of Facial Injuries in Motor Vehicle Accidents According to the Location of the Seat and Seat-Belt Use

The purpose of this study was to evaluate facial trauma in accidents involving a passenger car. In particular, the authors assessed differences in types of facial trauma and severity according to the location of the seat and seat-belt use. A 7-year retrospective review of data was conducted for 419 patients with facial trauma resulting from motor vehicle accidents. Patients who used a seat belt faced a lower risk of severe soft-tissue injury in comparison with having mild soft-tissue injury than patients who did not use a seat belt (P = 0.0129). Additionally, patients who used a seat belt had a lower risk of accompanying facial bone fracture requiring surgical operation than patients who did not use a seat belt (P = 0.0168). In terms of facial bone fracture according to seat location, patients who had sat in the back seat had more risk of accompanying facial bone fracture than patients who had sat in the passenger's seat (P = 0.0392). In terms of facial bone fractures requiring surgical operation, the patients who had sat in a back seat faced more risk of needing a surgical operation than patients who had sat in the driver's seat (P = 0.0479). The results of the study reveal that wearing a seat belt effectively reduces severe facial soft-tissue injury and facial bone fracture requiring surgical operation. In particular, the authors note that sitting in a back seat is riskier in terms of facial bone injury than sitting in a front seat.

Maxillofacial fracture epidemiology and treatment plans in the Northeast of Iran: A retrospective study

Background

The epidemiology of facial injuries varies based on lifestyle, cultural background and socioeconomic status in different countries and geographic zones. This study evaluated the epidemiology of maxillofacial fractures and treatment plans in hospitalized patients in Northeast of Iran (2015-2016).

Material and Methods

In this retrospective study, the medical records of 502 hospitalized patients were evaluated in the Department of Maxillofacial Surgery in Kamyab Hospital in Mashhad, Iran. The type and cause of fractures and treatment plans were recorded in a checklist. Data were analyzed with Mann–Whitney test, chi-squared test and Fisher’s exact test, using SPSS 21.

Results

The majority of patients were male (80.3%). Most subjects were in 20-30-year age range (43.2%). The fractures were mostly caused by accidents, particularly motorcycle accidents (MCAs), and the most common site of involvement was the body of the mandible. There was a significant association between the type of treatment and age. In fact, the age range of 16-59 years underwent open reduction internal fixation (ORIF) more than other age ranges (P=0.001). Also, there was a significant association between gender and fractures (P=0.002).

Conclusions

It was concluded that patient age and gender and trauma significantly affected the prevalence of maxillofacial traumas, fracture types and treatment plans. This information would be useful for making better health policy strategies.

Two years retrospective study of maxillofacial trauma at a tertiary center in North West Ethiopia

BACKGROUND

Maxillofacial injury poses a challenge to oral and maxillofacial surgeons working in developing countries with limited resource and human power. The present study aimed to determine the etiology, pattern, and management of maxillofacial trauma in Gondar university of Gondar hospital.

METHODS

A retrospective descriptive study design was used. Medical registration retrieving of patients with maxillofacial trauma visited dental center of University of Gondar Hospital from September 2013 to August 2015 was done. During data collection, etiology of trauma, pattern of fracture, treatment modality and complications were recorded using predesigned data collection template and analyzed using SPSS computer software version 20. Statistical analysis was done to show the sex distribution of maxillofacial trauma and the effect of alcohol intake on the incidence of trauma.

RESULTS

During 2-year period, September 2013-August 2015, 326 patients of maxillofacial trauma were treated in the dental center of university of Gondar hospital. The mean age was 29.12 (± 8.62) with age range of 11-75 years. Majority of the study participants (47.2%) were within the age group of 21-30 years. Eighty percent of the participants were male with a male to female ratio of 4.02:1. Interpersonal violence (75.8%) and Road traffic accident (21.5%) were the leading causes. Males are at high risk of maxillofacial trauma relative to females (P < 0.0001). There was high incidence of trauma in the weekend, rural residents, December to February, mandibular fractures and soft tissue injuries were the most common injuries. There was an associated injury in 79 (24.2%) patients in head and neck area, thoracic, abdominal and extremities. Half of the patients were managed conservatively (49.7%) with debridement and suture, while 45.7% of the patients were closed reduction and 4.6% were surgical open reduction. There were 25 post procedure complications especially in mandibular fractures.

CONCLUSION

Interpersonal violence was the major cause of maxillofacial trauma, while mandible and soft tissue were the most affected maxillofacial areas. The federal ministry of health, Ethiopia should have well-organized maxillofacial center in tertiary hospitals for emergency management to avoid morbidity and mortality.

Incidence and patterns of maxillofacial trauma-a retrospective analysis of 3611 patients-an update

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.

Retrospective study maxillofacial fractures epidemiology and treatment plans in Southeast of Iran

Background

The epidemiology of facial injuries varies in different countries and geographic zones. Population concentration, lifestyle, cultural background, and socioeconomic status can affect the prevalence of maxillofacial injuries. Therefore, in this study, we evaluated the maxillofacial fractures epidemiology and treatment plans in hospitalized patients (2012-2014) which would be useful for better policy making strategies.

Material and Methods

In this retrospective study, the medical records of 386 hospitalized patients were evaluated from the department of maxillofacial surgery at Bahonar Hospital of Kerman, Iran. The type and cause of fractures and treatment plans were recorded in a checklist. For data analysis, ANOVA, t-test, Chi-square, and Fisher’s exact test were performed, using SPSS version 21.

Results

The majority of patients were male (76.5%). Most subjects were within the age range of 20-30 years. Fractures were mostly caused by accidents, particularly motorcycle accidents (MCAs), and the most common site of involvement was the mandible (parasymphysis). There was a significant association between the type of treatment and age. In fact, the age group of 16-59 years under went open reduction internal fixation (ORIF) more than other age groups (P=0.02). Also, a significant association was observed between gender and the occurrence of fractures (P=0.01).

Conclusions

Considering the geographic and cultural indices of the evaluated population, it can be concluded that patients age and gender and trauma causes significantly affect the prevalence of maxillofacial traumas and fracture kinds and treatment plans.

Maxillofacial trauma and seat belt: a 10-year retrospective study

INTRODUCTION

Brazil is among the countries with the highest prevalence of people injured by traffic accidents, showing that in 2008, levels reached 18.3 victims for 100,000 habitants were victims of traffic accidents.

MATERIALS AND METHODS

This retrospective study involved data collected from treated patients' charts at seven different hospitals located in three different cities all in the state of São Paulo, Brazil. Information was obtained through a standardized form, which was designed to investigate the epidemiologic features of maxillofacial traumas, restricted to victims of car accidents.

RESULTS

Three hundred ninety-six patients were victims of car crashes with mean age 29.75 years. The age group 18-30 years showed an association with facial trauma in 96 patients, 41.56 % of whom reported using seat belt. Le Fort I, II and III (70 %) and mandible (63.11 %) were more associated with body traumas and seat belt use. The most common soft tissue lesion was laceration with 189 cases (42.3 %). The treatment way was assessed, 93 (23 %) were treated surgically and 303 (77 %) underwent conservative treatment.

DISCUSSION

Classically, it is known front seat belt use was positively correlated with back seat belt use, healthy diet, dental and general health, regular walking, adequate sleep and no smoking. Accidents involving cars occurred more frequently in age group 18-30 years, suffering more general traumas and representing the nonusers group that wore fewer seat belts, caused, perhaps, by bigger access of the youth to cars, driving in high speed and to an inefficient fiscalization of the traffic laws.

Metaanalysis of maxillofacial trauma in the northern districts of kerala: one year prospective study

PURPOSE

There is an increased incidence of maxillofacial trauma all over the world. A study was conducted to find out the epidemiological characteristics of maxillofacial trauma in Northern districts of Kerala.

METHODS

All the trauma patients who attended the Department of Oral and Maxillofacial Surgery, Government Dental College, Calicut, Kerala during the period of 2006-2007 was included in the study. The incidence, prevalence, age and sex distribution, seasonal and daily variations and aetiology of maxillofacial trauma were studied. The pattern and demographic distribution of fractures of maxillofacial skeleton also were studied.

RESULTS

This study indicates a significant increase in the incidence of maxillofacial trauma in the region. There was a male predominance and the highest incidence was in the age group of 20-40 years. Road traffic accident was the most common aetiological factor causing maxillofacial trauma. More than 30% of trauma cases suffered fracture of maxillofacial skeleton. There was an increased incidence of midface fracture when compared to mandibular fractures in the study. Most common site of mandibular fracture was in the parasymphysis region and in the midface was the zygomatic complex region.

CONCLUSION

The increased incidence of maxillofacial trauma following road traffic accidents noted in this study reveals the need for formulating preventive measures in the state of Kerala. Increasing facilities for the management of maxillofacial trauma at local hospitals and medical colleges is mandatory. Training of the paramedical personnel, health workers and also the public regarding first aid and primary trauma care is also necessary.

Factors influencing the incidence of maxillofacial fractures

PURPOSE

Maxillofacial injuries occur in a significant proportion of trauma patients. Trauma causes considerable economic expense due to procedural costs, the time a patient is off work, and the associated loss of income. For these reasons, it is an important health and economic issue. The aim of this study is to discuss the factors that may influence the incidence of maxillofacial fractures. As it is necessary to determine trends to help guide the development of new methods of injury prevention, preventative measures are also discussed.

METHODS

An electronic search was undertaken in March 2011, including articles published between 1980 and 2011 with the terms "facial fractures" and "maxillofacial fractures" in the title. The texts of epidemiological studies were reviewed in order to identify factors that may influence the incidence of maxillofacial fractures.

RESULTS

From the selected articles, ten factors were identified: age, gender, geographic region and cultural aspects, socioeconomic status, temporal and climatic influence, use of alcohol and drugs, compliance with road traffic legislation, domestic violence, osteoporosis, and etiology of the maxillofacial trauma.

CONCLUSIONS

Care of injured patients should include not only management of the acute phase, but also combine preventive programs and interventional programs aimed at reducing the incidence of maxillofacial fractures. Therefore, there is a need to ensure strict compliance of traffic rules and regulations, implement improvement in automotive safety devices, organize prevention programs to minimize assaults, implement school education in alcohol abuse and handling potentially hostile situations (especially for men), improve protection during sporting activities, and legislate wearing of protective headgear in workers. Preventive strategies remain the cheapest way to reduce direct and indirect costs of the sequelae of trauma. Societal attitudes and behaviors must be modified before a significant reduction in the incidence of maxillofacial fractures will be seen.

Injury risks in frontal crashes by delta V and body region with focus on head injuries in low-speed collisions

PURPOSE

This study investigated injury risks in frontal crashes by belt use and crash severity (delta V) with a focus on studying whether there is a pattern to the crashes causing serious head injuries in low-speed frontal collisions.

METHODS

1996-2007 National Automotive Sample System-Crashworthiness Data System (NASS-CDS) was analyzed for frontal crashes involving front-outboard occupants. Light vehicles were included with model year 1997+. Injuries of maximum severity MAIS 0-6 and fatalities were determined by crash severity and belt. Body region injury (AIS 0-6) was also determined. NASS-CDS electronic cases involving <15 mph crashes were evaluated to determine the crash circumstances causing serious head injury (AIS 3+) in occupants with overall severe injuries (MAIS 4+F).

RESULTS

More than half (51.3%) of belted occupants in 10-15 mph delta V crashes were uninjured compared with 30.2 percent for unbelted occupants. The ratio of the fraction (relative risk) of belted occupants who were uninjured to the fraction of unbelted, uninjured occupants was highest at 3.74 in the 30-35 mph delta V. For 10-15 mph crashes, 0.40 +/- 0.15 percent of unbelted occupants were severely injured (MAIS 4+F) compared to 0.033 +/- 0.009 percent for belted occupants. For 30-35 mph crashes, 8.51 +/- 2.20 percent of unbelted and 5.83 +/- 1.93 percent of belted occupants were severely injured. Overall, seat belt use was 87.4 percent effective in preventing severe injury (MAIS 4+F). The effectiveness decreased with increasing crash severity. The highest relative risk for severe injury of unbelted compared to belted occupants was 12.3 in crashes of 10-15 mph delta V. The relative risk was 8.8 in <10 mph crashes. Overall, the relative risk was 8.0 for severe injury (MAIS 4+F) in frontal crashes. 16.5 +/- 0.98 percent of unbelted occupants experienced serious (AIS 3-6) injury. This risk was 6.49 times greater than the 2.53 +/- 0.10 percent risk with belted occupants. The largest relative risk for serious injury (AIS 3-6) was to the neck (367 times), face (15.5 times) and head (10.2 times).

CONCLUSIONS

The highest relative risk for severe injury of unbelted occupants was in frontal crashes <15 mph. Most of the crashes involved multiple impacts and air bag deployment in the accident sequence. The use of long fill-time side curtains, additional curtain deployment logic, limited deflation front air bags and broader curtain coverage of the front interior may address these injuries.

Facial fractures in children and adolescents: a retrospective study of 3 years in a hospital in Belo Horizonte, Brazil

AIM

The purpose of this study was to review the etiology, incidence and treatment of selected oral and maxillofacial fractures in children in Belo Horizonte, Brazil, during a period of 3 years.

MATERIALS AND METHODS

The data collected for this study included age, gender, etiology, date of trauma, associated maxillofacial trauma, anatomic site of fracture and treatment. The analysis involved descriptive statistics and chi-squared test, Bonferroni test, Kolmogorov-Smirnov, Kruskal-Wallis and Mann-Whiney tests and analysis of variance.

RESULTS AND CONCLUSIONS

This study examined 566 facial fractures in 464 children of 18 years of age or less. The majority of fractures were observed in children within the age group of 13-18 years of age. Bicycle accidents were the major cause of trauma, followed by falls. The mandible was found to be the most common fractured bone in the facial skeleton, followed by the nose. A conservative approach was applied in most cases.

[Epidemiology of maxillofacial traumatology in Tunis]

INTRODUCTION

The aim of this study was to assess the epidemiology of maxillofacial trauma in Tunisia over a 10-year period.

METHODS

This retrospective study was carried out between 1995 and 2004 on patients admitted for maxillofacial trauma in the department of maxillofacial and plastic surgery of the Charles-Nicolle Hospital in Tunis. The selected relevant parameters were: age, gender, etiology, time of trauma, type of fracture and associated lesions.

RESULTS

A total of 1100 patient files were analyzed. The average age was 29 years and the sex-ratio was 6:1 in favor of men. The most common etiologies were: car crashes (39%), fights (28%) and domestic trauma (19%), occurred in the evening, on weekends and in the summer. The frequency increased in the evening, on weekends and in the summer. Mandibular fractures (62%) and zygomatic fractures (32%) were the most common trauma. Polytrauma occurred in 18% of the patients and cranial trauma in 10% of the cases.

DISCUSSION

Epidemiological investigations results vary according to demographic and cultural regional specificities. Long-term collection of epidemiological data in maxillofacial surgery is a major issue to plan educational campaigns and therapeutic strategies. In Tunisia, driver education and observance of traffic regulations should be improved.

Maxillofacial trauma in major trauma patients

BACKGROUND

Trauma has been identified as a major public health problem in Australia. Maxillofacial trauma constitutes a significant proportion of trauma, although epidemiological studies in Australia are few. The purpose of this study was to assess the prevalence and the epidemiological pattern of maxillofacial trauma occurring in major trauma patients.

METHODS

Data were obtained from the Victorian State Trauma Registry, which included all major trauma patients in Victoria. All data relating to maxillofacial trauma defined according to Abbreviated Injury Scale and International Classification of Diseases codes from 1 July 2001 to 30 June 2004 were selected. Data collected included demographic and injury details, and operative procedures carried out.

RESULTS

Sixteen per cent of major trauma patients sustained maxillofacial trauma. The highest frequency of injuries occurred in the 15-24 years age group. More males were affected than females (3:1). The majority of injuries were due to transportrelated causes (69 per cent) and occurred mostly on roads, streets or highways (70 per cent). Falls were the cause of 15 per cent of injuries, 10.5 per cent of these injuries were fatal while 20.7 per cent needed rehabilitation. The most common type of bony injury was a fractured maxilla.

CONCLUSION

The need for preventive strategies to be reinforced has been highlighted as transport-related injuries remain high especially in the younger age groups.

Seating position, seat belt wearing, and the consequences in facial fractures in car occupants

INTRODUCTION

Trauma caused by traffic accidents is among the main etiologies involved in the occurrence of facial fractures throughout the world. However, the trauma mechanisms involved are different according to the location where the study was performed, due to different conditions of development, legislation, and culture. A retrospective study was done between February 2001 and July 2006, with the purpose of determining the epidemiology and the mechanisms involved in the occurrence of facial fractures among car occupants in the metropolitan area of São Paulo.

METHODS

Data were collected from 297 patients admitted with facial fractures to the emergency room of the Hospital das Clínicas, São Paulo University Medical School. Within this period, 151 individuals had been involved in traffic accidents, among which 56 (37.08%) were inside passenger cars. These were grouped based on the seating position that they were occupying at the time of the accident and the wearing of seat belts. Data concerning the number and location of fracture lines were obtained from the different groups, and a fracture/patient index (F/P I) was calculated to compare and make reference to the impact energy among these groups, for subsequent analysis and discussion.

RESULTS

323 fracture lines occurred among 56 patients who were car occupants. By applying the F/P I, we obtained higher values in the group of rear-seat passengers who were not wearing seat belts (7.23 fractures per patient), followed by the group of drivers not wearing seat belts (6.33 fractures per patient), the group of front-seat passengers not wearing seat belts (5.58 fractures per patient), the group of drivers wearing seat belts (5.54 fractures per patient) and, finally, the group of front-seat passengers wearing seat belts (4.00 fractures per patient). None of the rear-seat passengers was wearing seat belts.

CONCLUSION

The data collected indicate that the driver position shows a high incidence of facial fractures, not being effectively protected by the seat belt, although the wearing of seat belts seems to have a protective role against the occurrence of facial fractures in front-seat passengers. It was not possible to evaluate the wearing of seat belts among rear-seat passengers, even though the high incidence of fractures in this group showed its high susceptibility to the occurrence of facial fractures, which highlights the need of taking protective measures against this situation.

Craniomaxillofacial Injuries in the United Arab Emirates: A Retrospective Study

PURPOSE

To analyze craniomaxillofacial injuries in selected hospitals in the United Arab Emirates (UAE).

PATIENTS AND METHODS

This is a retrospective study of craniomaxillofacial injuries treated in 3 major hospitals in the UAE. Patient files were retrieved, reviewed, and analyzed. The main analysis outcome measures were the patients' name, age, and gender and the injuries' time, site, type, treatment and outcome.

RESULTS

A total of 288 patients sustained 475 craniomaxillofacial injuries; road traffic accidents caused the majority of injuries. The patients ranged in age from 2 to 82 years (mean, 27.3 years), and the male-to-female ratio was 7:1. The yearly distribution of fractures peaked during 2001, and the monthly distribution peaked in January. The greatest number (41%) of patients were UAE nationals. Most patients (70.5%) had mandibular fractures, and the most common site was the body. There were 139 patients (48.3%) with a total of 171 midface fractures (36%); the most common fracture site was the zygomatic complex (29.8%). The most common treatment for jaw fractures was plating plus intermaxillary fixation. Stable zygomatic complex fractures were closely reduced (elevated), and unstable ones were treated by internal fixation. About 25% of the cases had 1 or more postoperative complication.

CONCLUSIONS

Craniomaxillofacial injuries in the UAE included in this study are somewhat similar to those reported in other countries. Differences from other countries are probably related to factors peculiar to the UAE, such as climate, social trends, and the cosmopolitan population.

Characteristics of maxillofacial injuries resulting from road traffic accidents--a 5 year review of the case records from Department of Maxillofacial Surgery in Katowice, Poland

Background

In spite of employing numerous devices improving the safety in motor vehicles, traffic accidents are still among the main reasons of maxillofacial injuries. The maxillofacial injuries remain the serious clinical problem because of the specificity of this anatomical region. The knowledge of etiologic factors and mechanisms of injuries can be helpful in a satisfactory trauma prevention. The aim of this study was to find out the incidence and the pattern of maxillofacial injuries resulting from traffic accidents in the patients treated in the Department of Maxillofacial Surgery (Silesian Medical Academy in Katowice, Poland) from January 2001 to December 2005.

Methods

The material consisted of 1024 case records of patients with maxillofacial injuries treated in the Maxillofacial Surgery Department of Silesian Medical Academy. The detailed analysis was carried out on the case records of 198 patients in the age of 3 to 68 with maxillofacial injuries resulting from traffic accidents. On the basis of data from a history, examination on admission, consultations and radiological examinations, patients' age and gender, we obtained the information on a pattern of injury and detailed description of an accident (the date and the time of an accident, the role of the patient in an accident).

Results

The traffic accidents were the cause of 19,93% maxillofacial injuries in the analyzed period of time. Most of the patients had injuries to the soft tissues of the face (22,21%), followed by tooth and alveolar process injuries (20,71%) and mandibular fractures (18,69%). All the types of injuries were more common in men than in women. The majority of the patients were car drivers followed by car passengers, pedestrians, cyclists and motor cyclists. The peak age of the patients was between 18 to 25 years. The prevalent number of accidents resulting in injuries to this region took place in spring, especially between noon and 4 PM.

Conclusion

Our results exhibit that road traffic accidents remain among the main reasons of maxillofacial injuries following the traumas resulting from assaults and interpersonal violence. This succession of etiologic factors is in accordance with the data from the most developed countries. The relatively high incidence of injuries resulting from traffic accidents indicates the necessity to reinforce legislation aimed to prevent road traffic crashes and thus to reduce maxillofacial injuries among children and adults.
