Epidemiology of Craniomaxillofacial Fractures Over a 5-year Period at a Midwestern Level 1 Trauma Center Serving a Large Rural Population.

BACKGROUND: Though the epidemiology of craniomaxillofacial (CMF) fractures has been well documented at urban hospitals, the characteristics of these fractures in rural hospitals have not been well studied. PURPOSE: The purpose of this study is to report on the epidemiology of CMF fractures at a regional Level 1 trauma center serving a large rural population in central Illinois. STUDY DESIGN, SETTING, SAMPLE: This is a retrospective cohort study at a community-based regional tertiary referral center that serves a predominantly rural population. Inclusion criteria comprised patients with radiologically confirmed CMF fractures between 2015 and 2019. Patients with incomplete medical records were excluded. PREDICTOR VARIABLE: Predictor variables included demographics (age, admission source, race, and sex) and etiology of CMF fracture (assault/domestic violence, all-terrain vehicle/off-road, falls, farm-related, motor vehicle collisions, gunshot wound, and others). MAIN OUTCOME VARIABLE: The primary outcome variable was the CMF anatomic location including nasal bone, orbit, mandible, malar/maxillary, and other CMF fractures. COVARIATES: The covariates are not applicable. ANALYSES: Descriptive statistics were used to summarize a sample of the population characteristics. Wilcoxon ranked sign tests and χ2 tests of independence were used to assess for statistically significant associations between select variables of interest. Statistical significance was defined as P < .05. RESULTS: Between 2015 and 2019, a total of 2,334 patients presented to the emergency department with a CMF fracture. After applying the inclusion/exclusion criteria, the final sample was composed of 1,844 patients for the management of 2,405 CMF fractures. The majority of patients were male(62.0%) and young adults (aged 18-39) had the highest number of CMF fractures (819) relative to all other age groups. The most common fracture etiology was fall(37.3%), and nasal bone fractures represented the most common fracture location(41.6%). χ2 analyses revealed statistically significant associations between the anatomic location of CMF fracture incurred, and differing categories of age, admission source, race, sex, and etiology. CONCLUSION AND RELEVANCE: Our study shows that patients seen at our Midwestern Level 1 trauma center are more likely to present with nasal bone and malar/maxillary fractures due to falls. In studies based in urban centers, patients are likely to present with orbital and mandibular fractures due to falls and assault.

Complications and complaints in craniofacial fractures - Finnish national data for 20 years.

OBJECTIVE: Research on reasons for malpractice claims in oral and maxillofacial surgery is scarce. The aim of this study was to investigate the causes and prevalence of permanent harm among craniofacial fracture related malpractice claims. MATERIALS AND METHODS: A retrospective register study was designed and implemented. All patients with a complaint and a diagnosis of facial or cranial fracture were included. The main outcome was the presence of permanent harm, and the predictor variable was the cause of complaint. Chi-square test was used for estimation of statistical significance. RESULTS: Delay in correct diagnosis was the leading cause of malpractice claims (63.2%), and permanent harm was found in 23.1% of the population. 82.4% of injuries were facial fractures in total population. 65.3% (n = 98) of facial trauma were related with delayed diagnostics (p < 0.001). Permanent harm was more frequent in patients with delayed diagnosis (71.4%) than those without (60.7%, p = 0.299). CONCLUSIONS: Claims of craniofacial trauma are related with under-diagnostics, and un-diagnosed facial fracture can lead to a high rate of permanent harm. Systematic clinical evaluation and facial trauma specialist consultation is recommended to set early correct diagnosis for and improve treatment of craniofacial trauma patients.

The pattern of maxillofacial fractures associated with rollover accidents: A 7-year retrospective study.

BACKGROUND/AIM: This study aimed to assess the incidence and pattern of maxillofacial fractures and related demographic data in the victims of rollover crashes. PATIENTS AND METHODS: This retrospective study was based on medical records of patients who sustained maxillofacial injuries following rollover accidents. Investigated data included age, gender, accident date and time, accident cause, seat belt usage, airbag deployment, road type, anatomical location of the facial fracture, and treatment approach. RESULTS: Among the 147 patients who met the inclusion criteria, the most prevalent age groups were 20-30 (36.7%) and 30-40 (32.7%) years, with a mean age of 33.6 ± 9.7 years. The male-to-female ratio was 6:1. Most crashes occurred in March, August, and July. These accidents involved 69.4% light vehicles and 39.6% heavy vehicles. The leading causes of rollover crashes were speeding (58.5%) followed by distracted driving (21.1%) and traffic rule violations (13.6%). The most prevalent injuries were fractures of the maxillary sinus wall (40.8%), nasal bones (39.5%), zygomaticomaxillary complex (36.1%), and the mandible (32.6%). Surgical intervention was necessary for 44.2% of patients, while 12.9% of cases underwent close reduction, and 42.9% did not require any surgical intervention. The occurrence of nasal bone fractures was significantly lower in cases where seat belts were worn and zygomatic arch fractures were less frequent in incidents with airbag deployment. CONCLUSIONS: In rollover crashes, the midface is the most vulnerable anatomical location. Utilization of seat belts and airbag deployment has the potential to prevent nasal bone and zygomatic arch fractures.

Interfacility Emergency Department Transfer for Midface Fractures in the United States.

PURPOSE: Interfacility hospital transfer for isolated midfacial fractures is common but rarely clinically necessary. The purpose of this study was to generate nationally representative estimates regarding the incidence, risk factors, and cost of transfer for isolated midface fractures. METHODS: This was a retrospective cohort study using the Nationwide Emergency Department Sample 2018 to identify patients with isolated midface fractures. The primary predictor variable was hospital trauma center designation (Level I, Level II, Level III, and nontrauma center). The primary outcome variable was hospital transfer. Total emergency department (ED) charges were also assessed. Covariates were demographic, medical, injury-related, and hospital characteristics. Descriptive, bivariate, and multiple logistic regression statistics were used to evaluate the incidence and predictors of interfacility transfer. RESULTS: During the study period, there were 161,022 ED encounters with a midface fracture as primary diagnosis, of which 5,680 were transferred (3.53%). In an unadjusted analysis, evaluation at a nontrauma center, level III trauma center, nonteaching hospital, and numerous demographic, medical, and injury-related variables were associated with transfer (P ≤ .001). In the adjusted model, the strongest independent predictors for hospital transfer were evaluation at a nontrauma center (odds ratio [OR] = 16.2, 95% confidence interval [CI] = 13.6-19.4), level III trauma center (OR = 13.4, 95% CI = 11.1-16.1) or level II trauma center (OR = 3.25, 95% CI = 2.66-3.98), any Le Fort fracture (OR = 12.0, 95% CI = 10.4-14.0), orbital floor fracture (OR = 3.73, 95% CI = 3.48-4.00), history of cerebrovascular event (OR = 2.74, 95% CI = 2.18-3.45), and cervical spine injury (OR = 5.87, 95% CI = 4.79-7.20) (P ≤ .001). The average ED charge per encounter was $7,206 ± 9,294 for a total nationwide charge of approximately 1.16 billion dollars. Transferred subjects had total ED charges of $97 million, not including additional charges at the recipient hospital. CONCLUSION: Isolated midface fractures are transferred infrequently, but given the high incidence have substantial healthcare costs. Predictors of transfer were mixed rather than clustered within one variable type, although it is likely that transfers are driven in part by lack of access to maxillofacial specialists given the predominance of hospital covariates. Programs evaluating necessity of transfer and facilitating specialist evaluation in the outpatient setting may reduce healthcare expenditures for these injuries.

Management Strategies for Geriatric Maxillofacial Fractures: An Anthropometric and Clinical Study in Taiwan.

BACKGROUND: Geriatric maxillofacial trauma has become an increasingly pressing clinical issue in Taiwan because of increased life expectancy. AIM AND OBJECTIVES: The purposes of this study were to investigate the anthropometric changes and the posttrauma outcomes in the aging population and to optimize the management strategies for geriatric facial fractures. MATERIALS AND METHODS: From 2015 to 2020, a total of 30 patients 65 years or older were identified to have suffered from maxillofacial fractures and presented at the emergency department of the Chang Gung Memorial Hospital (CGMH). These patients were categorized into group III, representing the elderly group. Two other groups (group I, age 18-40 years; group II, age 41-64 years) of patients were categorized based on their age. After applying propensity score matching to reduce bias caused by a large case number difference, patient demographics, anthropometric data, and management methods were compared and analyzed. RESULTS: Among 30 patients 65 years or older who met the inclusion criteria, the mean age of the matched group III was 77.31 ± 14.87 years, and the mean number of retained teeth was 11.77 (range, 3-20 teeth). The elderly patients had a significantly lower number of retained teeth (group I vs group II vs group III, 27.3 vs 25.23 vs 11.77; P < 0.001). Anthropometric data showed that facial bone structure degenerated significantly with advancing age. Outcome analysis demonstrated that falls accounted for 43.3% of injury mechanisms in the elderly group, followed by motorcycle accidents (30%) and car accidents (23.3%). Nineteen elderly patients (63%) received nonsurgical management. On the other hand, 86.7% of cases in the other 2 age groups underwent surgery. The average numbers of total hospital and intensive care unit stays in group III patients were 16.9 (range, 3-49 days) and 4.57 (range, 0-47 days), which was significantly longer than the other 2 age groups. CONCLUSIONS: Our results suggested that not only surgery is feasible for elderly patients with facial fractures, but an acceptable result is often obtainable. However, an eventful course, including extended hospital/intensive care unit stays and an increased risk of associated injuries and complications, may be expected.

Facial Fractures in Indigenous and Non-indigenous Populations of South Australia.

INTRODUCTION: Maxillofacial trauma in indigenous populations is complex with sociocultural factors, access to health care, and poorer general health issues that impact outcomes. Assaults and road traffic accidents are disproportionately experienced by indigenous persons compared with non-indigenous. METHODS: A retrospective review was conducted from January 2012 to January 2017 at the Women and Children's Hospital and Royal Adelaide Hospital, Adelaide. All maxillofacial fractures that attended or were referred to the unit were included in this study. The primary objective was to analyze epidemiological trends of facial fractures and clinical outcomes in the South Australian indigenous and non-indigenous populations. RESULTS: Maxillofacial fractures in indigenous persons were less than in non-indigenous (31.2 versus 38.2 y, P < 0.001) with 3.8 odds of a facial fracture. Assault was 2.9 times more likely to result in a facial fracture, falls 40.9% less likely, and sports 29.4% less likely compared with non-indigenous ( P < 0.001). Alcohol-related facial fractures had significantly higher rates [odds ratio (OR = 3.8)] compared with non-indigenous. Indigenous from most disadvantaged areas and very remote areas also had significantly higher odds of a facial fracture. Indigenous persons had higher operative rates (OR = 2.8), postoperative complications (OR = 3.1), and a 3.7-day mean difference for the length of stay (6.6 versus 2.9 d, P < 0.001). CONCLUSIONS: Indigenous people are more likely to experience facial fractures from assault resulting in mandibular fractures, whereas non-indigenous people are likely to have sport or fall-related midface fractures. Young indigenous women from outer regional and very remote areas have greater odds of facial fractures caused by assault and alcohol with higher operative rates, postoperative complications, and extended length of stay.

Analysis of Nasal Bone Fractures: A 17-year Study of 3785 Patients.

In our previous study, we classified nasal bone fractures into 6 types based on computed tomography and the patterns of the nasal bone fractures (NBF) in 503 patients treated between 1998 and 2004. In the present study, we analyzed 3785 patients treated between 2005 and 2021. The age, sex, etiology, associated injuries, pattern of fractures, and treatments were reviewed, and radiographic studies were analyzed. The highest incidence was in the age group of 10 to 19 years (N=870, 23.0%), followed by 20 to 29 years (N=792, 20.9%) and 30 to 39 years (N=635, 16.8%). The most common causes of injury were slip or fall-down (42.3%), violence (24.3%), sports (19.2%), traffic accidents (8.9%), and work-related (5.3%). Most of the patients had tenderness (96.1%) and swelling (78.8%). Other findings were depression (27.1%) and nasal deviation (25.8%). Crepitus was heard in only 0.4% of the patients. The patterns of the NBFs classified by computed tomography findings were type IIA (unilateral simple fracture with displacement/without telescoping, 1283 cases, 33.9%), IIB (bilateral simple fracture with displacement/without telescoping, 786 cases, 20.8%), IIAs (unilateral simple fracture with septal fracture and displacement/without telescoping, 566 cases, 14.9%), IIBs (bilateral simple fracture with septal fracture and displacement/without telescoping 530 cases, 14.0%), I (simple fracture without displacement, 522 cases, 13.8%), and III (comminuted with telescoping or depression, 98 cases, 2.6%). In most of the cases (3,666, 96.9%), closed reduction was performed. The present analysis is one of the largest data sets on NBF in Korea, which could provide reference values for diagnosing and managing nasal bone fractures.

Artificial Intelligence Model Trained with Sparse Data to Detect Facial and Cranial Bone Fractures from Head CT.

The presence of cranial and facial bone fractures is an important finding on non-enhanced head computed tomography (CT) scans from patients who have sustained head trauma. Some prior studies have proposed automatic cranial fracture detections, but studies on facial fractures are lacking. We propose a deep learning system to automatically detect both cranial and facial bone fractures. Our system incorporated models consisting of YOLOv4 for one-stage fracture detection and improved ResUNet (ResUNet++) for the segmentation of cranial and facial bones. The results from the two models mapped together provided the location of the fracture and the name of the fractured bone as the final output. The training data for the detection model were the soft tissue algorithm images from a total of 1,447 head CT studies (a total of 16,985 images), and the training data for the segmentation model included 1,538 selected head CT images. The trained models were tested on a test dataset consisting of 192 head CT studies (a total of 5,890 images). The overall performance achieved a sensitivity of 88.66%, a precision of 94.51%, and an F1 score of 0.9149. Specifically, the cranial and facial regions were evaluated and resulted in a sensitivity of 84.78% and 80.77%, a precision of 92.86% and 87.50%, and F1 scores of 0.8864 and 0.8400, respectively. The average accuracy for the segmentation labels concerning all predicted fracture bounding boxes was 80.90%. Our deep learning system could accurately detect cranial and facial bone fractures and identify the fractured bone region simultaneously.

Evidence-Based Medicine for Midface/Orbit/Upper Facial Fracture Repair.

The face is one of the most common areas of traumatic injury, making up approximately 25% of all injuries in 2016. Assault, motor vehicle collision (MVC), fall, sports, occupational, and gunshot wounds (GSW) are all common causes of facial fractures, with MVC and GSW leading to significantly higher severity of injuries. Most facial fractures occur in the upper two-thirds of the face. Most facial fractures require timely assessment, diagnosis, and treatment for optimal restoration of facial structures and functions. Without proper initial management, significant complications including immediate complications such as airway compromise, massive bleeding, infection, intracranial hemorrhages, or even death, and long-term complications such as poor functional outcomes and aesthetic setbacks can occur. The goal of this review is to summarize the management of fractures of the upper face, orbit, and midface and provide an update about complications and their management.

Epidemiological aspects of dental trauma associated with maxillofacial injures: Ten years of clinical experience in Trieste, Italy.

BACKGROUND/AIMS: The prevalence of dental injuries in patients with facial fractures is relevant. Epidemiologically, dental trauma in association with facial fractures generally affects the age group between 20 and 40 years old, with a higher prevalence in males. The aim of this retrospective study was to identify the incidence and etiology of dental trauma associated with facial fractures over a 10-year period. METHODS: From January 2009 to April 2019, among 381 patients with facial fractures, 353 were included in this study. Age, gender, trauma etiology, injured teeth and dental treatment were investigated. RESULTS: From 353 patients, with a mean age of 49.7 ± 19.9 years, 247 (70%) were males and 106 (30%) were females. Accidental falls were the most common type of injury (n = 118, 33.4%), followed by road accidents (n = 90, 25.5%), assaults (n = 60, 17%) and sports trauma (n = 37, 10.5%). Fifty-five subjects (15.60%) had dental injuries associated with facial fractures. Of the 145 teeth involved, 48 (33.1%) were diagnosed with luxation, 22 teeth (15.2%) were avulsed, 11 teeth (7.5%) suffered a concussion and there were 10 (6.8%) alveolar wall fractures.Uncomplicated enamel-dentin fracture was the more frequent hard tissue injury (n = 21, 14.5%), followed by complicated crown-root fracture (n = 10, 6.9%), infraction (n = 8, 5.5%), enamel fracture (n = 3, 2%) and complicated enamel-dentin fracture (n = 3, 2%). There was a peak in incidence between 21 and 40 years (42%). Males had a significantly higher risk of facial fractures with dental injury (75%). Maxillary incisors and canines (62.8%) were the most affected teeth. CONCLUSIONS: There was a high prevalence of dental injuries associated with facial fractures. Maxillary incisors were the most injured teeth, with a higher prevalence in males.

Mind the Difference: Characterizing the Impact of Behavioral Health Disorders on Facial Trauma.

BACKGROUND: Patients with psychiatric diagnoses are at greater risk for traumatic injury than the general population. Current literature fails to characterize how premorbid behavioral health disorders (BHDs) complicate craniofacial trauma. This study aimed to describe the characteristics and outcomes of patients with premorbid BHD sustaining facial fractures. METHODS: All adults in the 2013-2016 Trauma Quality Improvement Program datasets with facial fractures were identified. Demographics, injury characteristics, fracture patterns, and in-hospital outcomes were compared in patients with and without premorbid BHDs. BHDs included major psychiatric illnesses, alcohol or drug use disorders, attention deficit hyperactivity disorder, or dementia. RESULTS: Twenty-five percent of the 240,104 subjects with facial fractures had at least one premorbid BHD. Assault (29.9% versus 23.9%, P< 0.001), self-inflicted injury (2.9% versus 1.2%, P< 0.001), and multiple facial fractures (40.2% versus 38.7%, P< 0.001) were more common among the BHD group. The BHD group displayed significantly higher rates of nearly all in-hospital complications, including pneumonia (4.3% versus 3.3%, P< 0.001), substance withdrawal (3.9% versus 0.3%, P< 0.001), unplanned intubation (1.5% versus 0.9%, P< 0.001) and unplanned transfer to the intensive care unit (ICU, 1.3% versus 0.8%, P< 0.001). BHD was strongly predictive of pneumonia, unplanned intubation, and unplanned ICU admission in multivariate analyses. CONCLUSIONS: Patients with BHD represent a subset of facial trauma characterized by different mechanisms and patterns of injury and premorbid health status. BHDs are associated with higher in-hospital complication rates and resource utilization. Understanding the relationship between craniofacial trauma and premorbid BHD creates opportunities to improve morbidity and resource utilization in this group.

Most Facial Fractures Do Not Require Surgical Intervention.

PURPOSE: Literature describing the number of patients that had a facial fracture that required surgical intervention in the United States is very limited. The purpose of this study was to evaluate the percentage of patients who required surgical intervention after presenting to a Level 1 Trauma Center with 1 or more facial fractures. MATERIALS AND METHODS: This was a retrospective cross-sectional study of all patients who presented with facial fracture(s) to University Hospital, a Level 1 Trauma Center (San Antonio, Texas), over a 5-year period from July 2015 to July 2020. Patients' charts that had 1 or more International Classification of Diseases 10 codes pertaining to facial fractures were collected. Cases were subdivided by fracture location: mandible, midface, upper face, or a combination of any of the aforementioned locations (predictor variables). After subdividing based on location, each chart was then reviewed and separated based on whether or not surgical intervention was provided (primary outcome variable). Data were tabulated and analyzed with descriptive and inferential statistics. RESULTS: Over the 5-year period, 3,416 patients presented with facial fractures. Of the 3,126 patients who survived their injuries and were not lost to follow-up, the vast majority (80.9%) did not require surgical intervention for their facial fractures. Mandible fractures required surgical intervention, whether isolated or in combination, much more frequently than in patients who did not have any type of mandible fracture (RR 8.01, 95% CI 6.92-9.27, P < .05 and RR 4.60, 95% CI 3.42-6.18, P < .05, respectively). Patients aged 50 years or less were also more likely to receive surgical intervention than those aged 51 years and more (RR 1.98 95% CI 1.63-2.41, P < .05). CONCLUSIONS: The vast majority of facial fractures that present to a Level 1 Trauma Center do not require surgical intervention. Patients who present with any type of mandible fracture and are aged 50 years or less are more likely to need surgical intervention.

Are Facial Soft Tissue Injury Patterns Associated With Facial Bone Fractures Following Motorcycle-Related Accident?

PURPOSE: The unprotected nature of motorcycle riding exposes motorcyclists to an elevated risk of sustaining facial soft tissue injuries (STIs); however, its link with underlying facial bone fractures remains unexplored. The purpose of this study is to determine whether the type and site of STI sustained by motorcyclists were associated with the presence of underlying facial bone fractures. MATERIALS AND METHODS: This was a retrospective cohort study of patients identified from the Oral and Maxillofacial Surgery Department of Universiti Kebangsaan Malaysia Medical Center trauma census who had motorcycle-related injury and met the inclusion criteria. The primary predictor variable was the type (laceration, contusion, abrasion, and no injuries) and site of STIs sustained. The site of the facial STI was categorized as per 17 different zones based upon the modified MCFONTZL classification. The primary outcome variable was the presence or absence of facial bone fractures as determined from the computed tomography scan. Descriptive and bivariate statistics were computed to measure the association between sustaining facial bone fractures and type/site of STI. RESULTS: Seventy three patients (65 men and 8 women) were included in this study. The average age was 31.9 years (standard deviation ± 13.6) with a range of 18 to 70 years. There were 1,241 facial zones being assessed with 285 (23%) and 214 (17%) zones having STI and fractures, respectively. Laceration (124/285, 43%) and the orbital zone (53/285, 19%) were the most common type and site of STI, respectively, among motorcyclists. Facial bone fractures are more commonly seen following STI in the midface (71% of STI had fractures) compared to upper face (53%) and lower face (31%). Sustaining laceration type of STI was not associated with a higher rate of facial bone fracture when compared with other type of STI (54.8% vs 55.9%, P = .858) with the exception of laceration in the frontal zone (42.9% vs 10.5%, P = .022). CONCLUSIONS: The different types of STI in the facial area cannot be used as a predictor for sustaining underlying facial bone fractures.

Patterns of Mandibular Fractures in South Australia: Epidemiology, Treatment, and Clinical Outcomes.

INTRODUCTION: The mandible is one of the most common facial bones to be injured with great clinical variability across countries caused by assaults, road traffic accidents, and falls. METHODS: A retrospective review was conducted for adult mandibular fractures from January 2012 to January 2017 at the Royal Adelaide Hospital, Adelaide. Our aim was to describe epidemiological trends of mandibular fractures, differences for sex and age, and clinical outcomes. RESULTS: Five hundred sixty five adult patients presented with a mandibular fracture with a male predominance (4.5:1). The mean age was 34.2 years with men 11.9 years younger than females (32.0 versus 44.1 years, P   <  0.001). Assaults represented 58.2% of cases. A quarter of the cohort reported alcohol use. Assaults commonly resulted in angle and symphyseal fractures, whereas almost all falls and road traffic accident resulted in condylar or coronoid fractures. Young men were 1.9 times more likely to have mandibular fractures compared to women, whereas elderly men were 11.8% less likely ( P  < 0.001). The most common fracture was the angle (33.6%) and the angle/symphyseal (14.2%). Men were 2.5 times more likely to have surgery. The complication rate was 10.8% and the re-operative rate was 5.0%. Women had a significantly longer admission of 1.6 days compared to men (4.4 versus 2.8 days, P  = 0.003). CONCLUSIONS: Young men are more likely to have mandibular fractures from assaults and have surgery. Young women and elderly females are more likely to have animal and fall-related injuries resulting including in condylar fractures with associated injuries and extended length of stay.

Etiology of Nasal Bone Fracture: A Retrospective Analysis of 1,441 Patients in China.

ABSTRACT: Nasal bone fracture is the most common injury in the craniofacial area. Understanding the etiology of nasal bone fracture is important for the development of preventive public health programs. In this study, the authors retrospectively examined medical records to extract information about sex, age, injury time, injury cause, occupation, and place of residence (urban or rural) from 1441 patients with nasal bone fracture to investigate the etiology of nasal bone fracture in China. Among the 1441 patients, the ratio of males to females was 3.4:1. The mean patient age was 29.25 years. The most common occupation was student (31.02%). Violence was the most common cause of injury in male patients (35.82%), whereas slip-and-fall accidents were the most common cause in female patients (32.11%). Violence was the most common cause of injury in both urban and rural patients, and 74.19% were attacked by others without a weapon. This report provides important data about the etiology of nasal bone fracture in China and will help improve nasal bone fracture prevention measures.

Characteristics and Patterns of Facial Fractures in the Elderly Population in the United States Based on Trauma Quality Improvement Project Data.

ABSTRACT: With the increase in the elderly population in the United States, the number of people seeking care for trauma injuries is expected to increase. However, nationwide studies on epidemiological profile of elderly facial fractures remain sparse. The authors present the epidemiological measures of elderly facial fractures on national scale. Characteristics of facial fractures among younger adults (18-64 years old) and the elderly population (65-74 years old, 75-84 years old and 85 years and above) have been examined using the 2016 American College of Surgeons-Trauma Quality Improvement Program databank. Variables studied included facial fracture patterns, mechanisms of injury, treatment variables, and demographic descriptive data. Of 104,183 elderly trauma patients, 3415 presented with facial fractures, making up 3.3% (versus 6.5% in younger adults). Majority of facial fractures in 85 and over group (60.7%) were experienced by females, compared to only 19.5% in the younger adult group. Most common mechanism of injury in the elderly was falls, versus motor vehicle trauma in younger adults. The most common type of facial fractures among both groups were nasal fractures. Elderly patients presented with fewer zygoma, mandibular and nasal fractures when compared to younger adults, whereas showing more maxillary/malar and orbital bone fractures. Elderly patients experienced less operative management (4.3%-8.2%) compared to younger adults (15.6%). Concurrently, mortality rates were higher in the elderly patients (9.9%-11.8%) when compared to the younger adults (8.0%). Elderly patients presented with different causes of injury, distribution of fractures, and rates of operative management compared to younger adults.

Comparing diagnosis of midfacial fractures by radiologists and plastic surgeons.

BACKGROUND: Clinicians who manage facial fractures often rely on radiologist interpretations to help with assessment and management. Among treating physicians, facial fractures are categorized into clinically relevant patterns of injury. On the other hand, while radiologists are unsurpassed at identifying individual breaks in the bone, larger fracture patterns are not always conveyed in radiology reports. PURPOSE: This study aims to assess the frequency with which the terminology describing midfacial fracture patterns is concordant among radiologists and treating clinicians. METHODS: The authors identified patients with different patterns of midfacial injury including Le Fort I, Le Fort II, Le Fort III, naso-orbito-ethmoid (NOE), and zygomaticomaxillary complex (ZMC) fractures. Plastic surgery consult notes and radiological imaging reports were reviewed for concordance in documentation of injury patterns. Identification of individual fractures consistent with the diagnosed fracture pattern was also recorded. RESULTS: Radiologists were noted to be highly successful in describing individual fractures of the facial bones, identifying at least two defining components of a fracture pattern in 96% of Le Fort, 88% of NOE, and 94% of ZMC injuries. However, when injury patterns were considered, only 32% of Le Fort, 28% of ZMC, and 6% of NOE fractures were explicitly identified in radiology reports. CONCLUSIONS: Radiologists are highly skilled in discerning individual fractures in facial trauma cases. However, less reliability was seen in the identification of fracture patterns in midfacial injury, with particular weaknesses in descriptions of NOE and ZMC fractures. This data suggests that greater focus on patterns of midfacial injury would improve the clinical applicability of radiological reports.

Malar and maxillary fractures among pediatric patients and the risk factors for mortality.

BACKGROUND/AIMS: No studies have characterized the morbidity and mortality of maxillary & malar fractures on a national scale. The aim of this study was to examine the risk factors for mortality in pediatric patients who had sustained maxillary and malar fractures by using a national pediatric hospital inpatient care database. MATERIALS AND METHODS: This retrospective cohort study was conducted using the Kids' Inpatient Database (KID). The primary predictor variable was the cause of injury. The primary outcome variable was mortality rate. Additional predictor variables included age, gender, race, income, payer information, year and place of injury, number of facial fractures, concomitant facial fractures, other fractures of the body, and intracranial/internal organ injury. Univariate and multivariate regression models were performed to assess risk factors for mortality. Statistical significance was set to a p-value <.05. RESULTS: A total of 5859 patients met the inclusion criteria. The most common age group was 13-17 years of age (n = 3816, 65.1%). Motor vehicle accidents were the most common mechanism of injury (n = 2172, 37.1%). The presence of cranial vault (OR = 2.81, p = .017), skull base (OR = 2.72, p < .001), and vertebral column fractures (OR = 2.13, p = .016), as well as sub-arachnoid hemorrhage (OR = 4.75, p = .005), traumatic pneumothorax/hemothorax (OR = 2.16, p = .015), and heart/lung injury (OR = 3.37, p < .001) were each independently associated with increased odds of mortality. CONCLUSIONS: Patients in their late teens most commonly sustained malar and maxillary fractures, likely due to general trends in craniomaxillofacial development. The presence of other fractures located in close proximity to the mid-face increased the risk of mortality among pediatric patients with malar and maxillary fractures. This may be explained by the anatomical approximation of the mid-face to vital neurovascular structures of the head, which, when damaged, may prove fatal.

Helmet Usage Reduces Serious Head Injury Without Decreasing Concussion After Bicycle Riders Crash.

BACKGROUND: The importance of bicycle helmets in reducing injuries is unclear. Our center receives a disproportionate number of bicycle crash victims. We sought to evaluate the types of injuries observed and the role of helmets in reducing head injuries. MATERIALS AND METHODS: We evaluated demographic data and compared injuries between bicycle riders that crashed with and without helmets over a 9-year period. Categorical variables were compared using linear regression methods and nominal variables using ANOVA. Differences were considered significant for P ≤ 0.05. RESULTS: There were 906 patients evaluated, 701 with helmets (77%) and 205 (23%) without helmets. The mean Injury Severity Score was 9.3 ± 6.4. The most common injuries were concussion (n = 385), rib fractures (n = 154), clavicle fractures (n = 139), facial fractures (n = 102), and cervical spine fractures (n = 89). There was no significant difference in the number of patients with a concussion in riders with or without helmets, [299/701, 42.6% versus 86/205, 42.0%, respectively, (P = NS)]. In helmet versus no helmet riders, there were significantly fewer patients with facial fractures, [67/701, 9.5%, versus 35/205, 17.0%, respectively, (P = 0.003)], skull fractures [8/701, 1.1% versus 9/205, 4.4%, respectively, (P = 0.003)], and serious head injuries [6/701, 0.85% versus 8/205, 3.9%, respectively, (P = 0.002)]. CONCLUSIONS: Helmeted patients involved in bicycle crashes are less likely to sustain a serious head injury, a skull fracture, or facial fractures compared to riders without helmets. The most common injury in patients with a bicycle crash is a concussion. Helmets did not prevent concussion after bicycle rider's crash in our patient population.

Facial Fractures Related to Soccer.

ABSTRACT: Soccer is one of the most popular sports in the world. Despite the concept that soccer is not a violent game, it can lead to several injuries in amateur and professional settings, including facial fractures. Previous studies of facial fractures in soccer were all retrospective and, to date, no prospective studies are available in the literature.The authors performed a comprehensive literature search using the terms "soccer" AND "facial fracture" OR "craniofacial fracture" and "football" AND "facial fracture" OR "craniofacial fracture" and retrieved 693 articles. After applying inclusion and exclusion criteria, 11 articles were included in the present study.A total of 647 patients had suffered facial trauma, with a male-to-female ratio of 63.7:1. The patients' mean age was 27.3 years.The articles reported 670 fractures as follows: 219 (32.7%) in the zygoma, 197 (29.4%) in the nasal bone, 153 (23.6%) in the mandibula, 54 (8.0%) in the orbital wall, 12 (1.8%) in the frontal sinus, 10 (1.5%) in the alveolar bone, 3 (0.4%) in the maxilla, 3 (0.4%) in a Le Fort pattern, and 1 (0.1%) in a naso-orbito-ethmoid (NOE) pattern.Sports are a frequent cause of maxillofacial trauma and are responsible for 9.2% to 33.2% of such injuries. Soccer is a contact sport more associated with lower-limb injuries, but with a significant rate of facial fractures. As soccer is a popular sport played without facial protection and involving high-intensity movements and contact, the prevention of facial fractures related to this sport is crucial to improve the players' safety.
