Facial fractures in a level I trauma centre: the importance of protective devices and alcohol abuse

Maxillofacial trauma in the gulf countries: a systematic review

PURPOSE

The objective of this review was to determine the prevalence, major causative factors and the most common sites of Maxillofacial Trauma in the Gulf Cooperation Council (GCC) Countries.

METHODS

All articles that were published in the English language in the databases such as Google Scholar, EBSCO, PubMed, NCBI, Medline, COCHRANE, ELSEVIER and SCOPUS were reviewed for MFT from GCC during the last 23 years.

RESULTS

A total of 19,151 patients (16,567 males and 2584 females) (86-14%) with an age range between 0 and 97 years were included in the study. In all of the Gulf countries males outnumber females in terms of maxillofacial injuries with a ratio of 6.4:1. The mandible was the most common site of trauma followed by the maxilla. Road Traffic Accidents (RTA) was the most common cause of injury in the GCC followed by falls.

CONCLUSION

Maxillofacial injuries are highly prevalent, distributed among the Gulf countries, and is mainly caused by RTAs especially among males who are highly prone to MFT in the gulf. The reasons are due to lack of road safety culture and weak enactment of traffic legislation, other possible factors include intrinsic car safety features, high speed driving and the amount/use of highways in these societies.

Do Helmet Use and Type Influence Facial Trauma Occurrence and Severity in Motorcyclists? A Systematic Review and Meta-analysis

PURPOSE

This article consists of a systematic review of the literature, which verified whether the use and types of helmets reduce the occurrence and severity of facial fractures in hospitalized motorcyclists after traffic accidents.

MATERIALS AND METHODS

Prevalence studies and cohort studies, published in Latin American languages with no restrictions on publication dates, were considered. Two authors independently screened reference lists for eligible articles, assessed them for inclusion criteria, and extracted the data using a specific form. Twenty-six articles were selected, all prevalence studies.

RESULTS

The patients who used a helmet had a lower prevalence and severity of facial fractures, compared to patients who did not wear a helmet. There were no differences in the occurrence of lower third fractures between patients who used or did not wear a helmet at the time of the trauma; as well as in meta-analysis of occurrence and severity of facial trauma between helmet types (open or closed).

CONCLUSIONS

It can be concluded that the use of helmet leads to a lower number of fractures and severity of trauma when compared to nonuse. Regarding the type of helmet, there was no difference in the occurrence and severity of facial fracture in individuals who used closed or opened helmets.

An epidemiological analysis of maxillofacial fractures: a 10-year cross-sectional cohort retrospective study of 1007 patients

Background

Epidemiological data is providing vital indicators for organizing the financial resources related to a particular type of trauma, estimating expenses and training of dental practioners and ambulatory medical staff for collaboration with a certain pattern of patients. Knowing the etiology and epidemiology of a certain pathology is significant for approaching its means of prevention.

Methods

A 10-year retrospective statistical analysis of 1007 patients with maxillofacial fractures treated in a University Clinic of Oral and Maxillofacial Surgery in Romania was performed. The data were extracted from patients’ medical records. Statistical analysis was performed. A value of p < 0.05 was considered statistically significant.

Results

The incidence of maxillofacial fractures was high among patients in the 20–29 age group (35.9%). Male patients (90.57%, M:F = 9.6:1), having a low level of education (46.60%) and living in urban areas (53.50%) were more affected. The main cause of maxillofacial fractures was interpersonal violence (59.37%), both in the mandibular and midface topographic regions (p = 0.001, p = 0.002). In urban areas, fractures caused by interpersonal violence and road traffic accidents were predominant, while in rural areas, most of the fractures were due to interpersonal violence, domestic accidents, work accidents and animal attacks (p = 0.001).

Conclusions

Interpersonal violence is the main cause of maxillofacial fractures having epidemic proportions. Male patients aged 20–29 years with a low level of education represent the major risk category. Considering the wide area of interpersonal aggression, both the medical staff in the hospital and in the dental offices must be educated in order to collaborate with possible violent patients. Dentists must be prepared to work on a post-traumatic dento-periodontal field. Taking all measures to prevent inter-human aggression is imperative and will lead to a major decrease in maxillofacial fractures and an overall increase of oral health in a population.

Epidemiology of facial fractures: incidence, prevalence and years lived with disability estimates from the Global Burden of Disease 2017 study

BACKGROUND

The Global Burden of Disease Study (GBD) has historically produced estimates of causes of injury such as falls but not the resulting types of injuries that occur. The objective of this study was to estimate the global incidence, prevalence and years lived with disability (YLDs) due to facial fractures and to estimate the leading injurious causes of facial fracture.

METHODS

We obtained results from GBD 2017. First, the study estimated the incidence from each injury cause (eg, falls), and then the proportion of each cause that would result in facial fracture being the most disabling injury. Incidence, prevalence and YLDs of facial fractures are then calculated across causes.

RESULTS

Globally, in 2017, there were 7 538 663 (95% uncertainty interval 6 116 489 to 9 493 113) new cases, 1 819 732 (1 609 419 to 2 091 618) prevalent cases, and 117 402 (73 266 to 169 689) YLDs due to facial fractures. In terms of age-standardised incidence, prevalence and YLDs, the global rates were 98 (80 to 123) per 100 000, 23 (20 to 27) per 100 000, and 2 (1 to 2) per 100 000, respectively. Facial fractures were most concentrated in Central Europe. Falls were the predominant cause in most regions.

CONCLUSIONS

Facial fractures are predominantly caused by falls and occur worldwide. Healthcare systems and public health agencies should investigate methods of all injury prevention. It is important for healthcare systems in every part of the world to ensure access to treatment resources.

Epidemiological Analysis of Zygomatic Bone Fractures in North-Western Romanian Population: A 10-Year Retrospective Study

BACKGROUND/AIM

Midface fractures represent a challenge for medical practitioners due to the severe esthetic and functional consequences. This study aimed to determine the causes and to provide a demographic analysis of zygomatic bone fractures in our geographical area, with a view to implementing the necessary prevention methods, training the medical staff for a certain type of patients and decreasing the required costs.

PATIENTS AND METHODS

A retrospective statistical epidemiological analysis of 242 patients with zygomatic bone fractures over a 10-year period was performed.

RESULTS

The most affected age group was 20-29 years (27.27%). The most affected were men (n=211, 87.19%) from urban areas (n=140, 57.85%), and without education (n=122, 50.41%). The most frequent cause was interpersonal violence (54.04%), followed by falls (17.36%) and road traffic accidents (16.53%).

CONCLUSIONS

Interpersonal violence as a cause of zygomatic bone fractures is currently reaching epidemic proportions. Taking legal measures to prevent aggression is a public health emergency that would considerably decrease the incidence of these fractures in our population.

The effect of alcohol on facial Trauma outcomes: an analysis of the National Trauma Data Bank

Maxillofacial trauma costs emergency departments approximately one billion dollars annually. Facial trauma has increased since 2000 and has been attributed to both increased use of computed tomography and interpersonal violence. Alcohol, male sex, and age 18-35 years are significant risk factors for interpersonal violence. This study is novel in using a large database to look at the effect of alcohol on clinical outcomes in facial trauma. A data analysis was performed in Stata/MP 14.2 using variables coded from the National Trauma Data Bank (NTDB); logistic regression was applied. A total 580,313 patient records were analyzed. Operations for facial fractures were performed in 20.19% of cases (n = 117,139). A positive alcohol test reduced the odds of requiring operative fixation in both the unadjusted (odds ratio (OR) 0.8, 95% confidence interval (CI) 0.79-0.82, P < 0.001) and adjusted (OR 0.67, 95% CI 0.66-0.68, P < 0.001) models. Age and being struck (adjusted OR 1.99, 95% CI 1.91-2.07, P < 0.001) or shot (adjusted OR 1.95, 95% CI 1.84-2.06, P < 0.001) had a significant effect on operative fixation. Injury mechanisms related to interpersonal violence appeared to have higher operative fixation rates. This study did not find a correlation between acute intoxication and the need for an operative intervention. This further demonstrates the multifactorial nature of facial trauma and stresses the importance of injury and violence prevention on clinical outcomes.

Alcohol Intoxication-Related Soft Tissue Injuries in Patients With Orbital Wall Fractures

BACKGROUND

To date, involvement of alcohol intoxication (AI) in the occurrence of traumatic bone injuries has been well described in the literature. Still, however, there is a paucity of data regarding its involvement with soft tissue injuries in the oral and maxillofacial region. Considering that it is one of the significant predisposing factors that are involved in facial bone fractures in assault victims, we have speculated that they are also vulnerable to soft tissue injuries. We therefore examined the incidence, type and, pattern of soft tissue injuries in patients with trauma owing to the AI in a single-institution setting.

MATERIALS AND METHODS

A total of 488 patients underwent reconstructive surgery for orbital wall fracture at our medical institution between 2012 and 2017. Of these, 162 eligible patients were enrolled in the present study; they were divided into 2 groups (the AI group and the control group) based on a history of the AI. Then, we compared baseline and clinical characteristics, including the incidence, type, and pattern of soft tissue injury, between the 2 groups.

RESULTS

In our series, assault was the most common cause of traumatic injuries. We found that the patients with AI were at increased risks of preoperatively developing subconjunctival hemorrhage and diplopia and postoperatively developing infraorbital nerve (ION) hypesthesia.

CONCLUSIONS

In conclusion, our results indicate that the AI is closely associated with the preoperative risks of subconjunctival hemorrhage and diplopia and the postoperative risks of ION hypesthesia. But further large-scale, multicenter studies are warranted to establish our results.

Epidemiological study of facial fractures at the Oral and Maxillofacial Surgery Service, Santa Casa de Misericordia Hospital Complex, Porto Alegre - RS - Brazil

ABSTRACT Objectives: to investigate the incidence and etiology of face trauma with diagnosis of facial fracture treated at the Buccomaxillofacial Surgery and Traumatology Service of the Santa Casa de Misericórdia Hospital Complex in Porto Alegre. Methods: we conducted a cross-sectional, retrospective epidemiological study of 134 trauma victims with 153 facial fractures. Results: the male gender was the most affected (86.6%) and the incidence was higher in the age group from 21 to 30 years. The main etiology was assault (38.8%), followed by motor vehicle accidents (14.2%), motorcycle accidents (13.4%), falls (9%), road accidents (6.7%), sports accidents (5.2%), work accidents (5.2%), firearm injuries (4.5%) and cycling accidents (3%). The most frequent fractures were those of the zygomatic complex (44.5%), followed by fractures of the mandible (42.5%), maxillary bone (5.2%), nasal bones (4.5%) and zygomatic arch (3.3%). Conclusion: the fractures of the zygomatic complex and the mandible were the ones with the highest incidence in the facial traumas, having physical assaults as their main cause.

Single-stage soft tissue reconstruction and orbital fracture repair for complex facial injuries

BACKGROUND

Orbital fractures with open periorbital wounds cause significant morbidity. Timing of debridement with fracture repair and soft tissue reconstruction is controversial. This study focuses on the efficacy of early single-stage repair in combined bony and soft tissue injuries.

METHODS

Retrospective review. Twenty-three patients with combined open soft tissue wounds and orbital fractures were studied for single-stage orbital reconstruction and periorbital soft tissue repair. Inclusion criteria were open soft tissue wounds with clinical and radiographic evidence of orbital fractures and repair performed within 48 h after injury. Surgical complications and reconstructive outcomes were assessed over 6 months.

RESULTS

The main outcome measures were enophthalmos, pre- and post-CT imaging of orbits, scar evaluation, presence of diplopia, and eyelid position. Enophthalmos was corrected in 16/19 cases and improved in 3/19 cases. 3D reconstruction of CT images showed markedly improved orbital alignment with objective measurements of the optic foramen to cornea distance (mm) in reconstructed orbits relative to intact orbits of 0.66, 95% confidence interval [CI] (lower 0.33, upper 0.99) mm. The mean baseline of Stony Brook Scar Evaluation Scale was 0.6, 95%CI (0.30-0.92), and for 6 months, the mean score was 3.4, 95%CI (3.05-3.73). Residual diplopia in secondary gazes was present in two patients; one patient had ectropion. Complications included one case of local wound infection.

CONCLUSIONS

An early single-stage repair of combined soft tissue and orbital fractures yields satisfactory functional and aesthetic outcomes. Complications are low and likely related to trauma severity.

The association between healed skeletal fractures indicative of interpersonal violence and alcoholic liver disease in a cadaver cohort from the Western Cape, South Africa

Interpersonal violence (IPV) and heavy alcohol consumption are major problems in the Western Cape Province of South Africa. Cranio-maxillofacial fractures, particularly nasal and zygomatic bone fractures, as well as isolated radial fractures (Colles fractures) and ulnar shaft fractures (parry fractures), are indicative of IPV, while alcoholic liver disease (ALD) is the consequence of chronic alcohol abuse. We therefore aim to investigate whether a significant association exists between the prevalence of cranio-maxillofacial fractures and parry fractures and ALD in a Western Cape population. Embalmed cadavers (n = 124) used for medical students' anatomy training at the Division of Anatomy and Histology, Faculty of Medicine and Health Sciences, Stellenbosch University were studied. The cadavers were dissected according to departmental protocol. The liver of each cadaver was investigated for macroscopic pathology lesions. Tissue samples were removed, processed to wax, and sectioned and stained with hematoxylin and eosin (H&E). All soft tissue was removed from the skulls, radii, and ulnae, which were then investigated for healed skeletal trauma. The results showed 37/124 (29.8%) cadavers had healed cranio-maxillofacial fractures and 24/124 (19.4%) cadavers had morphologic features of ALD. A total of 12/124 (9.7%) cadavers showed signs of both ALD and healed cranio-maxillofacial trauma. More males were affected than females, and left-sided facial fractures were statistically more common compared to the right side. This study illustrated a significant trend between alcohol abuse and cranio-maxillofacial fractures in individuals from communities with a low socio-economic status (SES) where IPV is a major problem.

Impact of Injury Mechanisms on Patterns and Management of Facial Fractures

Mechanisms causing facial fractures have evolved over time and may be predictive of the types of injuries sustained. The objective of this study is to examine the impact of mechanisms of injury on the type and management of facial fractures at our Level 1 Trauma Center. The authors performed an Institutional Review Board-approved review of our network's trauma registry from 2006 to 2010, documenting age, sex, mechanism, Injury Severity Score, Glasgow Coma Scale, facial fracture patterns (nasal, maxillary/malar, orbital, mandible), and reconstructions. Mechanism rates were compared using a Pearson χ2 test. The database identified 23,318 patients, including 1686 patients with facial fractures and a subset of 1505 patients sustaining 2094 fractures by motor vehicle collision (MVC), fall, or assault. Nasal fractures were the most common injuries sustained by all mechanisms. MVCs were most likely to cause nasal and malar/maxillary fractures (P < 0.01). Falls were the least likely and assaults the most likely to cause mandible fractures (P < 0.001), the most common injury leading to surgical intervention (P < 0.001). Although not statistically significant, fractures sustained in MVCs were the most likely overall to undergo surgical intervention. Age, number of fractures, and alcohol level were statistically significant variables associated with operative management. Age and number of fractures sustained were associated with operative intervention. Although there is a statistically significant correlation between mechanism of injury and type of facial fracture sustained, none of the mechanisms evaluated herein are statistically associated with surgical intervention. Clinical Question/Level of Evidence: Therapeutic, III.

Maxillofacial Fractures in Women and Men: A 10-Year Retrospective Study

PURPOSE

The purpose of this study was to evaluate and compare the demographic characteristics of maxillofacial fractures between women and men in China.

PATIENTS AND METHODS

The sample was composed of all patients who sustained maxillofacial fractures during a 10-year period (2000 through 2009). Incidences, age distributions, etiologies, fracture patterns, associated injuries, and occupation distributions were recorded and analyzed. Data analysis included the χ(2) test, the Fisher exact test, and the t test. A P value less than .05 was considered significant.

RESULTS

There were 1,131 patients (881 male and 250 female) who sustained maxillofacial fractures, with a male-to-female ratio of 3.5:1. Male patients sustained injuries most frequently during the autumn (P = .048), whereas female patients sustained more maxillofacial injuries during the summer (P = .006). Men sustained motorcycle (P = .023) and assault-related accidents (P = .036) more frequently than women, whereas women were more frequently injured in bicycle-related accidents (P < .001) or falling while at ground level (P = .001) than men. Women presented more frequently with condylar fracture than men (P = .028), whereas men were more prone to symphysis fractures than women (P = .037). For drivers, only men were involved (P = .001). Male workers sustained maxillofacial fractures more frequently than female workers (P < .001). Female children, students, and company staff were more prone to maxillofacial fractures than their male counterparts (P = .010, P = .004, and P = .044 respectively).

CONCLUSIONS

The demographic characteristics of maxillofacial fractures in female patients considerably differ from those in male patients.

Analysis of radiographically confirmed blunt-mechanism facial fractures

Facial fractures resulting from blunt-mechanism trauma, although common, have been infrequently evaluated in large studies that do not include confirmation of fractures based on author review of available patient radiographic studies. An 8-year review (1998-2006) of the R Adams Cowley Shock Trauma Registry was performed with institutional review board approval. Patients diagnosed with blunt-mechanism facial fractures were identified by the International Classification of Diseases, Ninth Revision (ICD-9) codes and their facial fractures confirmed by author review of computed tomographic scans. Individual fractures were classified and grouped according to the facial thirds. Intra- and interreader variability was calculated, and confirmed fracture patterns were compared to fracture patterns listed by ICD-9 codes. Concomitant injuries and demographic data were additionally evaluated. Four thousand three hundred ninety-eight patients with 8127 fractures were identified. Intra- and interreader variability was 2% and 7%, respectively. ICD-9 coding misdiagnosed 12.5% of all fractures. Eighty-two percent of patients sustained associated injuries, including basilar skull fractures (7.6%) and cervical spine fractures (6.6%). 1.1% had at least one fracture in each facial third (panfacial fracture pattern). Significant relationships were found between demographic parameters, concomitant injuries, specific fractures, and fracture patterns. Studies investigating facial fractures should report fracture patterns confirmed by author review of available radiographic imaging. Large retrospective data sets containing confirmed fractures and capable of addressing rare fracture patterns can be compiled with low inter- and intrauser variability, and are useful for generating mechanistic hypotheses suitable for evaluation in prospective series or by directed biomechanical studies.

Minimal invasive and cost-effective method in reduction of maxillofacial fracture by using a Foley catheter ballooning technique

The purpose of this study was to introduce 2 successful cases of orbital inferior wall fracture and maxillary sinus anterior wall fracture using the Foley catheter ballooning technique. One patient is a 43-year-old man with left orbital inferior wall fracture. A window on the sinus was made for visualization, and a Foley catheter was accessed through the natural ostium. The ballooned catheter was inflated to lift the inferior orbital wall rim and stationed for 2 weeks. The window was closed using metal plates and screws. Another patient is a 64-year-old woman with right maxillary sinus anterior wall fracture, nasal fracture, and orbital blow-out fracture. A Foley catheter was accessed through the fractured maxillary sinus and reduced into place and fixed with absorbable plates screws. The technique of stabilization of reduced maxillofacial fractures using a Foley balloon catheter with restorable plates and titanium plates showed stable results. This technique is relatively easy to undergo with minimal or no complications because of reduced operation time. Also, it is cost-effective compared with other materials providing similar results and heightens patient satisfaction.

Reconstruction of the scalp, calvarium, and frontal sinus

Scalp and cranial deformities are common after trauma or ablative surgery. Local flaps and free flaps may be used in reconstruction of soft tissue defects, and autogenous bone or alloplastic bone substitutes may be used for cranioplasty procedures. Injuries to the frontal sinus, particularly when complicated by leak of cerebrospinal fluid or obstruction of the nasofrontal outflow tract, represent special challenges. Further studies are recommended to improve the multidisciplinary management of these complex, debilitating conditions, in anticipation of enhanced function and cosmesis, reduced donor site morbidity, and improved surgical outcomes.

Is there a change in the epidemiology of nasal fractures in females in the UK?

OBJECTIVE

To determine whether there is a change in the epidemiology of nasal fractures in females in the UK, and the potential contribution of the 'ladette' culture.

METHODS

This paper reports a multi-centre retrospective study. Operating theatre data for all females who underwent manipulation of nasal fractures under anaesthesia between 2002 and 2009 were analysed. In addition, the case notes of all females presenting with nasal fractures over a five-year period (2004-2009) were retrospectively reviewed and the cited cause of the fracture was noted.

RESULTS

From 2002 to 2009, there was an 825 per cent increase in nasal fractures in women aged 13-20 years. Almost one-quarter of all nasal fractures in one centre was attributed to non-domestic violence. The highest incidence of nasal fractures (67 per cent) was amongst white British females.

CONCLUSION

There is an increasing trend in the number of women sustaining nasal fractures in the UK. The cause may be multi-factorial, but could be partially attributed to a rise in ladette culture. Further research on the role of alcohol consumption in this phenomenon is needed.

Study of the pattern of maxillofacial fractures seen at a tertiary care hospital in north India

AIM

The present study was planned to investigate the etiology of maxillofacial injuries and to analyze the pattern of maxillofacial factures as well as the various factors influencing their distribution.

STUDY DESIGN

A one year cross-sectional study was done and 1,108 patients with maxillofacial fractures were analyzed consecutively from April 2010 to March 2011 who reported to the department of Oral and Maxillofacial Surgery in the Centre for Dental Education & Research and Jai Prakash Narayan Apex Trauma Centre, AIIMS, New Delhi. A performa was designed to collect the data that included age and sex distribution, etiology, influence of alcohol, type of fractures, use of restraints devices, associated injuries and treatment delivered.

RESULTS

Out of 1,108 patients, 89.62 % were males with a male:female ratio of 8.63:1. The 21-30 year age group was found to be maximum (39.98 %). Road traffic accidents accounted for 49.01 %, followed by assault (22.38 %) and fall from height (21.66 %). Two wheelers were the most commonly involved vehicle. Out of 437 road traffic accident patients (excluding pedestrian, n = 106), only 52.40 % were found to be using restraints devices at the time of accident. Totally 25.45 % patients were under the influence of alcohol at the time of injury. According to anatomical distribution of fractures, mandibular fractures (33.57 %) were most prevalent, followed by maxilla (31.13 %), nasal (28.33 %) and zygoma (24.36 %). Head injuries (18.32 %) were found to be the most common associated injuries followed by lower limb fractures.

CONCLUSION

The motive behind executing this article is to analyze the various trends of facial fractures and all those factors that affect their distribution. A perfect understanding of pattern of maxillofacial fracture will assist the executors of health care in the treatment planning and management of facial injuries. Knowledge gained from the present study would influence in assessing the effectiveness of existing preventive measures and elaboration of future preventive measures and conducting new research.

An epidemiological study on pattern and incidence of mandibular fractures

Mandible is the second most common facial fracture. There has been a significant increase in the number of cases in recent years with the advent of fast moving automobiles. Mandibular fractures constitute a substantial proportion of maxillofacial trauma cases in Lucknow. This study was undertaken to study mandibular fractures clinicoradiologically with an aim to calculate incidence and study pattern and the commonest site of fractures in population in and around Lucknow. Patient presenting with history of trauma at various centers of maxillofacial surgery in and around Lucknow were included in this study. Detailed case history was recorded followed by thorough clinical examination, and radiological interpretation was done for establishing the diagnosis and the data obtained was analyzed statistically. Out of 66 patients with mandibular fractures, highest percentage was found in 21–30 years of age with male predominance. Road traffic accidents were the most common cause of fracture with parasymphysis being commonest site. Commonest combination was parasymphysis with subcondyle. There was no gender bias in etiology with number of fracture sites. The incidence and causes of mandibular fracture reflect trauma patterns within the community and can provide a guide to the design of programs geared toward prevention and treatment.

Clinical indicators of midface fracture in patients with trauma

BACKGROUND/AIM

Midface fractures are commonly present and difficult to diagnose in trauma patients. The objective of this study was to determine clinically accessible indicators of midface fracture.

MATERIAL AND METHODS

A case-control study design was used to determine clinical indicators of midface fracture. Population source was a level I trauma center registry for years 2007-2009. Cases had a documented midface fracture. Patient and trauma characteristics were compared between cases and controls. Multivariate logistic regression analysis determined significant indicators of midface fracture.

RESULTS

Study sample included 83 cases and 83 frequency-matched controls. Cases had a total of 211 fractures with a median of two midface fractures per person. Common fractures were orbital (41%), malar and maxillary (28%), and nasal bones (19%). Patients with midface fracture were significantly different than patients without midface fracture in severity of injury and were more likely to have a traumatic brain injury. Significant clinical indicators of fracture were maxillary sinus opacification, ethmoid sinus opacification, forehead laceration, periorbital contusion, epistaxis, and injury mechanism (P < 0.05). Patients with midface fracture had a 63 times greater odds for maxillary sinus opacification. The multivariable model correctly classified the presence and absence of midface fracture in 95% of study sample.

CONCLUSIONS

Determined indicators of midface fracture provided a high level of discrimination in fracture status. Indicators can be used by clinicians to help detect possible midface fractures. Future prospective research on midface fracture indicators can assist in establishing their generalizability and impact on fracture detection, care, and outcomes.

Etiology, diagnosis, and characteristics of facial fracture at a midwestern level I trauma center

Study purpose was to describe facial fracture frequency, demography, injury characteristics, and diagnostic modalities at a Midwestern level I trauma center. A retrospective review was conducted on a Midwestern trauma center registry for years 2008 and 2009. Patient and injury data were collected along with diagnostic modality for facial fracture patients. Comparative statistics were conducted on the basis of the number of facial fractures, route of admission, presence of traumatic brain injury, and gender. There were 154 patients diagnosed with 443 facial fractures, representing 5% of the trauma population. Median patient age was 45 years. Median number of fractures was 2. Fractures were frequently present in orbit (32%), malar bone and maxilla (26%), and the nasal bones (19%). Motor vehicle crash was the most common mechanism (47%). Most fractures were diagnosed with maxillofacial computed tomography (78%). Males had an odds ratio of 2.5 (95% confidence interval, 1.15-5.43) for multiple facial fractures and composed 67% of the sample. Traumatic brain injury was diagnosed in 71% of patients. This study of a medium-sized city and its surrounding rural areas revealed differences from studies in large urban centers. Differences included lower gender ratio, older average age, and mechanism of injury. While urban trauma centers report assault as a leading cause of facial fracture, this study noted higher frequencies of motor vehicle crash and falls and fewer assaults.

Maxillofacial injuries in western Iran: a prospective study

INTRODUCTION

Although the epidemiology of facial injuries has been studied in many populations, there is a paucity of information in the literature in this relation in the Middle East including Iran. The aim of this study was to assess the epidemiology and mode of treatment of facial injuries in western Iran.

MATERIAL AND METHODS

We examined all patients with a maxillofacial injury who presented to the outpatient department or who were hospitalized in the Besat Hospital of Hamedan City, Iran, between 20 December 2007 and 20 December 2009.

RESULTS

Of 2,450 patients (77% male, 23% female) with a facial injury, 90% sustained soft tissue injuries and 37% had bone fractures. Motor vehicle accidents (MVAs) were the most common cause of injuries (35%). The most frequent bone fracture occurred in the nasal bone (63.4%). The incidence of associated injuries was 8.3% (mostly orthopedic). Rigid internal fixation was the main treatment of facial fractures. Malpositioned zygomas and functional and aesthetic problems after reconstruction of nasal-orbital-ethmoid injuries were the most common postoperative complications.

DISCUSSION

Although in many countries the rate of facial injuries due to traffic accidents is decreasing, MVA is still the major cause of facial trauma in Iran. This may be due to the lack of enforcement of traffic laws by police and insufficient compliance of the population in obeying traffic rules. Rigid internal fixation was the most common mode of treatment of facial fractures, and in spite of the severity of facial injuries, the rate of postoperative complications was relatively low.

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.

The Tolerance of the Frontal Bone to Blunt Impact

The current understanding of the tolerance of the frontal bone to blunt impact is limited. Previous studies have utilized vastly different methods, which limits the use of statistical analyses to determine the tolerance of the frontal bone. The purpose of this study is to determine the tolerance of the frontal bone to blunt impact. Acoustic emission sensors were used to provide a noncensored measure of the frontal bone tolerance and were essential due to the increase in impactor force after fracture onset. In this study, risk functions for fracture were developed using parametric and nonparametric techniques. The results of the statistical analyses suggest that a 50% risk of frontal bone fracture occurs at a force between 1885 N and 2405 N. Subjects that were found to have a frontal sinus present within the impacted region had a significantly higher risk of sustaining a fracture. There was no association between subject age and fracture force. The results of the current study suggest that utilizing peak force as an estimate of fracture tolerance will overestimate the force necessary to create a frontal bone fracture.

Trend of alcohol involvement in maxillofacial trauma

BACKGROUND

Ethanol is regularly consumed by individuals in social settings. However, overindulgence can lead to impaired judgment and physical harm. This study examines the trend of alcohol-related facial fractures at a tertiary trauma over 2 consecutive time periods.

STUDY DESIGN

A retrospective database of patients presenting to the Oral and Maxillofacial Surgery service at Christchurch Hospital during an 11-year period was reviewed, and data from the 2 5.5-year periods were compared. Variables examined included demographics, type of fractures, mode of injury, and treatment delivered.

RESULTS

A total of 1,264 patients were identified to have alcohol-related facial fractures, 624 in the first half of the period and 640 in the second half. More than 90% were male, with 66% of these patients in the 15-29-year age group in each period. Assault accounted for 73% in the first period and 82% in the second period, and motor vehicle accidents accounted for 18% and 8% of fractures, respectively, in the two periods. A total of 64% and 58% of these patients required hospital admission and surgery, respectively, in the first period, and 66% were hospitalised and 60% treated surgically in the second period.

CONCLUSION

There was no significant change between the 2 periods in terms of demographics, pattern of fractures, and treatment modality. The incidence of assault-related fractures were on the rise and motor vehicle accident-related fractures were declining. Alcohol-related fractures continued to be the main problem in young male adults involved in fights. There should be public awareness to educate these people on this harmful effect of drinking.

Perfil epidemiológico do trauma de face dos pacientes atendidos no pronto socorro de um hospital público

OBJETIVO: Avaliar os dados epidemiológicos e a localização dos traumas de face de pacientes atendidos no Hospital Regional da Asa Norte (HRAN), Brasília, Distrito Federal. MÉTODO: Trata-se de um estudo retrospectivo, realizado no pronto socorro do HRAN-DF, visando avaliar o perfil epidemiológico dos pacientes atendidos pela equipe da Unidade de Cirurgia Plástica vítimas de trauma de face no período de 1 de janeiro a 31 dezembro de 2004. RESULTADOS: O estudo compreendeu 711 pacientes, destacando-se o sexo masculino (72,8%). Quanto à causa, predominou a agressão física, seguida por acidente com veículos/motos. As quedas foram a causa predominante das lesões em crianças, mas verificou-se a participação cada vez maior da agressão física como mecanismo de trauma facial com o aumento da idade. A relação de homem:mulher foi de 3:1. A faixa etária mais atingida foi de 21 a 30 anos, representando 35,3% dos pacientes. As fraturas foram encontradas em 24,9% das lesões faciais. O nariz foi o local mais acometido nas fraturas de face (76,8%). CONCLUSÃO: A violência interpessoal foi a principal causa de trauma de face. A queda da própria altura mostrou-se como importante mecanismo de trauma nos extremos de idade.

Increased fatalities after motorcycle helmet law repeal: is it all because of lack of helmets?

BACKGROUND

During the last 10 years, the number of motorcycle riders in the United States has risen sharply. The corresponding increase in fatalities observed during this time may be because of the increase in riders, or because the number of states that mandate universal helmet use has decreased. We examined the effect of the repeal of Florida's helmet law in July 2000 to test the hypothesis that the increase in fatalities observed after repeal resulted from an increase in the number of motorcycle riders.

METHODS

We identified all motorcycle fatalities (N = 197) in Miami-Dade county for a 3.5-year period before repeal (prelaw), and a similar period after repeal (postlaw), using police crash reports and medical examiner records. We compared the number of fatalities, frequency of helmet use in fatal crashes, and number of registered motorcycles in the two time periods.

RESULTS

There was a decrease in helmet use from 80% to 33%, and an increase in motorcycle fatalities after repeal: 72 to 125. However, repeal was also associated with a rise in annual motorcycle registrations from 17,270 to 39,043. Fatality rates adjusted for numbers of registered motorcycles did not change significantly; 11.6 deaths per 10,000 motorcycles prelaw, and 12.5 deaths postlaw.

CONCLUSIONS

There was a significant rise in motorcycle fatalities after Florida's helmet law repeal, which appears to be associated with an increase in the number of motorcycle riders. Injury prevention efforts focusing on factors other than helmet use should be developed in light of continuing repeal of universal motorcycle helmet laws across the nation.

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.

THE RELATIONSHIP BETWEEN ACUTE ALCOHOL CONSUMPTION AND CONSEQUENT INJURY TYPE

AIMS

The aim of this study was to quantify the relationship between acute alcohol consumption and injury type (nature of injury, body region injured), while adjusting for the effect of known confounders (i.e. demographic and situational variables, usual drinking patterns, substance use and risk-taking behaviour).

METHODS

A cross-sectional study was conducted between October, 2000 and October, 2001 of patients aged >or=15 years presenting to a Queensland Emergency Department for treatment of an injury sustained in the preceding 24 h. There were three measures of acute alcohol consumption: drinking setting, quantity, and beverage type consumed in the 6 h prior to injury. Two variables were used to quantify injury type: nature of injury (fracture/dislocation, superficial, internal, and CNS injury) and body part injured (head/neck, facial, chest, abdominal, external, and extremities). Both were derived from patient medical records.

RESULTS

Five hundred and ninety three patients were interviewed. Logistic regression analyses indicated that, after controlling for relevant confounding variables, there was no significant association between any of the three measures of acute alcohol consumption and injury type.

CONCLUSIONS

The effects of acute alcohol consumption are not specific to injury type. Interventions aimed at reducing the incidence of alcohol-related injury should not be targeted at specific injury types.
