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

The effects of treatment timing on the management of patients with multiple facial fractures and on the self-perception of TMD recovery

OBJECTIVE

To investigate the effects of time on the orofacial functions and on the self-perception of temporomandibular disorders (TMD) recovery in a population of patients with multiple facial fractures.

METHODS

Orofacial functions and self-perception of TMD recovery was verified in patients with midface and/or lower face fractures. Patients were divided according to the time between fracture reduction and the clinical assessments: 0-1 month (Group 1), 1-3 months (Group 2), and 15 >3 months (Group 3).

RESULTS

Patients in Group 1 presented a greater compromise of swallowing and mastication when compared to patients with older fractures (p = 0.015), whereas patients in Group 3 presented a poorer TMD recovery (TMJ pain: p = 0.010 and tinnitus: p = 0.004).

CONCLUSION

Delays in functional treatments involving the myofunctional orofacial system have a negative impact on the recovery of essential orofacial functions and on TMD symptoms..

Treatment of Posttraumatic Zygomatic Coronoid Ankylosis. Systematic Review

Facial trauma is mostly associated with traffic accidents, fights, and sports accidents. The mandible, midface, and temporomandibular joint are usually the region's most frequently affected. Coronoid process fractures are rare, representing ∼2% of facial fractures in the literature, usually being the result of direct trauma to the zygomatic region. Due to the anatomical relationship of the coronoid process, it may be associated with other facial fractures, such as fractures of the zygomatic bone. Zygomatic-coronoid ankylosis is a rare clinical entity with variable etiology. It is most commonly associated with trauma (13%-100%), local or systemic infection (0%-53%), or systemic diseases, such as ankylosing spondylitis, rheumatoid arthritis, or psoriasis. The aim of this research is to evaluate the different treatments for ankylosis from the coronoid process to the zygoma after trauma, allowing to determine the treatment to obtain the best results. A systematic review was carried out following PRISMA "preferred reports for systematic reviews and meta-analyses" search matrix, based on a PICO question; was used PubMed, Embase, Sciencedirect, Cochrane, Google Scholar, and manual search in high-impact journals between 1946 and 2023 publications in English or Spanish, including randomized and nonrandomized clinical trials, prospective and retrospective cohort studies, case-control studies, series, and case reports. A total of 1993 articles were obtained from the 4 databases. After corroborating duplicate articles, 847 articles were excluded. Another 1112 articles were excluded in the title evaluation, and an additional 1093 after the abstract review; a total of 19 articles eligible for full-text evaluation were established and 1 article was added as a result of the manual search. After the full-text review, it was decided to include 16 articles in the study that met the objectives of the systematic review. After evaluating the different treatments described in the literature, the authors can determine that coronoidectomy through an intraoral approach is the most appropriate treatment for zygomatic coronoid ankylosis, accompanied by postoperative physiotherapy to achieve greater oral opening without recurrences.

Image quality of photon-counting detector CT for visualization of maxillofacial anatomy in comparison with energy-integrating detector CT and intraoperative C-arm CBCT

BACKGROUND

Accurate diagnostic imaging is crucial for managing facial fractures, which are a common global occurrence. This study aimed to compare the image quality of Photon Counting Detector CT (PCD-CT) with state-of-the-art Energy Integrating Detector CT (EID-CT) and intraoperative C-arm CBCT (CBCT) in visualizing maxillofacial anatomy using a cadaveric sheep head model.

METHODS

Three fresh sheep heads were used, with surgical interventions simulating metal implants in two of them. The specimens were imaged using PCD-CT, EID-CT, and CBCT, following which quantitative assessments of signal-to-noise ratio, sharpness, and artifacts were conducted. A visual grading study was performed by six observers, using criteria focusing on the mandible, orbit, and soft tissues. Statistical analyses included Friedman tests for comparing modalities and Kendall's W and Gwet's AC1 for assessing inter- and intrarater agreement.

RESULTS

PCD-CT demonstrated a significantly higher signal-to-noise ratio (p = 0.03) and bone sharpness (p < 0.001) compared to CBCT. In visual grading, PCD-CT outperformed CBCT, but not EID-CT, particularly in delineating mandibular and orbital structures. EID-CT and PCD-CT showed slightly more severe hypodense artifacts (p = 0.01) but were comparable in streak artifact presentation. The interrater and intrarater agreements indicated consistent evaluations across and within observers.

CONCLUSION

PCD-CT exhibits superior image quality over CBCT in key parameters essential for maxillofacial imaging, while no apparent improvement was shown compared to state-of-the-art EID-CT. PCD-CT offers enhanced visualization of critical anatomical structures, suggesting its potential as a preferred modality in managing maxillofacial trauma. The findings in this study align with limited existing research on PCD-CT, underscoring its promise for advanced diagnostic imaging in maxillofacial applications.

Maxillofacial Trauma in Females: A Retrospective Study

Maxillofacial trauma in females is not widely reported. This study aimed to analyze the clinical characteristics and the patterns of maxillofacial injuries in females and to determine the differences in these patterns among different causes. This retrospective study analyzed several variables, including demographic, social, injury-related, and treatment-related variables, and compared these variables in relation to the main etiologies of maxillofacial trauma. The main etiologies of maxillofacial injuries involving females were assault, followed by road traffic accidents, and falls. There were significant differences in relation to the 3 etiologies in age groups (P= 0.002) and marital status (P< 0.0001). There were significantly more soft tissue injuries in the assault group compared with the other groups (P= 0.007). Associated injuries were significantly more with injuries caused by road traffic accidents (P= 0.0009). Most females were victims of assault and violence. There were significant differences in relation to the etiology of trauma in terms of age groups, marital status, types of injury, and associated injuries. Most of the assaults were due to domestic violence.

Advances in Three-Dimensional Printing for Craniomaxillofacial Trauma Reconstruction: A Systematic Review

Craniomaxillofacial (CMF) fractures present significant challenges for plastic surgeons due to their intricate nature. Conventional methods such as autologous bone grafts have limitations, necessitating advancements in reconstructive surgery techniques. This study reviewed the use of three-dimensional printing for CMF trauma reconstruction using human studies. A systematic search of PubMed, EMBASE, and Google Scholar was conducted in February 2024 for case reports, case series, and clinical trials related to CMF trauma reconstruction using three-dimensional printing technology. The authors' systematic review included 20 studies and a total of 170 participants with CMF bone defects. In general, the authors observed low bias risk in analyzed case reports and series, serious bias risk in nonrandomized controlled trials, and moderate bias risk in randomized controlled trials. The printed objects included CMF structure model prototypes, patient-specific implants, and other custom surgical devices. Studies reveal successful outcomes, including restored facial symmetry and function, restored orbital occlusion, resolved enophthalmos and diplopia, achieved cosmetically symmetrical lower face reconstruction, and precise fitting of surgical devices, enhancing patient and surgeon comfort. However, complications such as local infection, implant exposure, and persistent diplopia were reported. Three-dimensional printed devices reduced surgery time but increased preparation time and production costs. In-house production options could mitigate these time and cost expenditures. Three-dimensional printing holds potential in CMF trauma reconstruction, addressing both functional and esthetic restoration. Nevertheless, challenges persist in implementing this advanced technology in resource-limited environments.

Patterns of Midface and Mandible Fractures in a Government Hospital

Study Design: Cross-sectional study. Objective: The prevalence and etiology of facial fractures differ in each country. The aim of this study was to determine the patterns, trauma mechanism, and treatment of midface and mandible fractures in a government hospital in Mexico City. Methods: A three-year cross-sectional study was done at Balbuena General Hospital in Mexico City. The variables of interest were age, gender, place of origin, fracture site, trauma mechanism, and treatment. Between 2016 and 2019, physical and electronic data records of patients that exhibited facial fractures were included. Statistical analyses performed included descriptive analysis and a chi-square test. Results: A total of 490 cases of fractures in the maxillofacial region were reviewed, of which 237 (47%) cases presented fractures in the midface. A higher male ratio (M: F 12:1) was observed. The age range varied between 18 and 80 years, with a mean of 35.58 ± 14 years. The most frequent diagnosis was a zygomatic complex fracture, 37.97%. (n = 90). The most frequent trauma mechanism was interpersonal violence at 55.93% (n = 132) in both places of origin (P = .06). Conservative treatment was more frequent at 71.67% in intrapersonal violence (P = .019). Interpersonal violence was more frequent in males at 61.64%, and motor vehicle accident was more frequent in female at 61.11% (P = .028). Conclusions: The analysis provides information that can help to focus preventive measures regarding facial fractures, especially on efforts to reduce interpersonal violence.

Factors influencing traumatic brain injuries in maxillofacial fractures: A 12-year retrospective analysis of 2841 patients

BACKGROUND/AIM

Results of studies investigating the association between traumatic brain injury (TBI) and maxillofacial fractures (MFs) have varied considerably. The present study aimed to evaluate the correlation between TBIs and MFs, as well as the impact of age, sex, trauma mechanism, and season on TBIs.

MATERIALS AND METHODS

This 12-year retrospective study of 2841 patients used univariate and multivariate logistic regression to assess the association between MFs and other factors impacting TBIs.

RESULTS

Among 2841 patients, 1978 TBIs occurred in 829 (29.2%), with intracranial injuries (n = 828) is the most common. Of 829 patients with TBIs, 688 were male and 141 were female, corresponding to a male-to-female ratio of 4.9:1.0. The most common age group was 40-49 years (24.6%). Vehicles (including motor vehicles and electric vehicles) accidents were the primary causes of injuries. Multivariate regression analyses revealed an increased risk for TBIs among males (odds ratio [OR] 0.632, p < 0.001). Patients >40 years of age were at higher risk for TBIs, especially those ≥70 years (OR 3.966, p = 0.001). Vehicle accidents were a high-risk factor for TBIs (OR 6.894, p < 0.001), and winter was the most prevalent season for such injuries (OR 1.559, p = 0.002). Risk for TBI increased by 136.4% in combined midfacial and mandibular fractures (p = 0.016) and by 101.6% in multiple midfacial fractures (p = 0.045). TBIs were less common in single mandibular fractures, notably in single-angle fractures, with a risk of only 0.204-fold.

CONCLUSION

TBIs in MFs were significantly correlated with sex, age, aetiology, season and fracture location. Maxillofacial surgeons and emergency physicians must be aware of the possible association between TBIs and MFs to assess and manage this complicated relationship in a timely manner.

The State of Craniomaxillofacial Trauma Care in Low- and Middle-Income Countries: A Scoping Review

Objective

This scoping review aims to contribute a descriptive analysis of the craniomaxillofacial trauma (CMF trauma) literature in low- and middle-income countries (LMICs) to identify knowledge gaps, direct future research, and inform policy.

Data Sources

PubMed/MEDLINE, Cochrane Review, EMBASE, ClinicalTrials.gov, and Google Scholar from January 1, 2012 to December 10, 2023.

Review Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guided reporting, and the PRISMA flowchart documented database searches. Specific, predefined search terms and inclusion criteria were used for screening, and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist was used for quality assessment. The search yielded 54 articles, with 13 meeting the inclusion criteria. Key findings were summarized and divided into 7 categories.

Results

There were 10,420 patients (7739 [74.3%] male, 2681 [25.7%] female) with a male-to-female ratio of 2.9:1. The mean peak age of incidence of CMF trauma was 30.8 years, ranging from 20 to 40 years. Road traffic accidents were the leading cause (60.4%), followed by assault (27.2%) and falls (12.2%). The most common injuries were soft tissue injury (31.7%), isolated mandibular fracture (22.8%), and isolated middle-third of mandible fracture (18.1%). The most common treatments were closed reduction and immobilization (29.5%), conservative management (27.6%), and open reduction and internal fixation (19.6%). Most patients (77.8%) experienced a treatment delay due to a lack of fixation materials (54.8%) or surgeon unavailability (35.7%).

Conclusion

CMF trauma remains a significant cause of global morbidity, yet there remains a lack of high-quality, CMF trauma-specific data in LMICs. Country-specific investigations are required to enhance knowledge and inform novel interventions. Implementing policy change must be community-specific and account for unique cultural barriers, attitudes, and behaviors to maximize patient care outcomes.

Craniofacial Assault Against Women: A National Evaluation Defining At-risk Populations and Outcomes

INTRODUCTION

Few studies have analyzed epidemiologic factor associated with female patients presenting to the emergency department from facial fractures because of assault. Clearly understanding these factors may assist in developing effective strategies to decrease the incidence and sequelae of these injuries.

OBJECTIVES

To determine the epidemiology of facial fractures because of assault in the female population.

METHODS

All female facial fracture visits were queried in the 2019 Nationwide Emergency Department (ED) Sample database. The likelihood of a facial fracture encounter resulting from assault was modeled using logistic regression adjusting for demographics, insurance status, geographic region, location of patient residence, and income. Secondary outcomes analyzed hospitalization costs and adverse events.

RESULTS

Of all facial fractures 12.4% of female encounters were due to assault were due to assault. Of assaulted females, 72.8% were between the ages of 20 and 40, and Black women experienced a disproportionate share of assault encounters (odds ratio [OR]=2.55; CI, 2.29-2.84). A large portion (46.4%) of encounters occurred in patients living in the lowest quartile of median household income, and 22.8% of patients were uninsured (OR=1.34; CI, 1.09-1.66). Assaulted patients were more likely to have fractures in nasal bone (58.1% vs. 42.5%), orbit (16.8% vs. 10.9%), zygoma (4.1% vs 3.6%), and mandible (8.7% vs. 4.8%) compared with their nonassaulted counterparts.

CONCLUSIONS

Facial fractures were especially common in lower income, uninsured, urban, and Black populations. Examining the patterns of injury and presentation are critical to improve prevention strategies and screening tools, identifying critical patients, and develop a more efficient and effective system to treat and support female patients suffering facial fractures secondary to assault.

Cost-Benefit Analysis of the CT of the Face in the Evaluation of Traumatic Facial Fractures in an Appalachian Tri-state Geriatric Population

OBJECTIVE

This study aimed to evaluate the cost vs. benefits of the CT face imaging study in the trauma workup of those over the age of 65.

METHODS

We performed a retrospective chart review of 169 trauma patients in our trauma database aged 65 years or older who underwent a CT of the head, a CT of the face, or a CT of the head and CT of the face that resulted in findings of a facial fracture from 2017-2022. Injuries and the treatment they received were documented. If a patient underwent both a CT of the face and a CT of the head, then the author first viewed the CT of the head, documented any injury, and then recorded treatment based on the CT of the head. The CT of the face was then viewed, injuries were recorded, and treatment based on the CT of the face was documented. Statistical analysis was then performed using the paired T-test, McNemar test, and number needed to harm analysis.

RESULTS

Of the 169 patients sampled, 159 underwent both CT of the head and the face. There were no patients who underwent a CT of the face exclusively, and only 10 patients underwent a CT of the head exclusively. Of the 159 that had both a CT of the head and the face, the average number of injuries noted on CT of the head + CT of the face vs. CT of the head was 2.42 vs. 1.36, P<.0.0001. The number needed to avoid missing a surgical facial fracture when only a CT of the head was obtained was 14.68.

CONCLUSION

The risks of missing a surgical facial fracture outweigh the monetary, radiation, and patient-desired necessity benefits of only performing a CT of the head. A CT of the face should be included in the trauma workup for those over the age of 65 when facial fractures are suspected.

Trends in Management and Cost Burden of Facial Fractures: A 14-Year Analysis

OBJECTIVE

To discuss patient demographics and management and better understand the economic impact associated with the treatment of facial fractures at a major metropolitan level 1 trauma center.

STUDY DESIGN

Retrospective chart review.

METHODS

We identified 5088 facial fractures in 2479 patients who presented from 2008 to 2022. Patient demographics, mechanism of injury, associated injuries, treatment information, and hospital charges were collected and analyzed to determine factors associated with surgical management and increased cost burden.

RESULTS

Our 14-year experience identified 1628 males and 851 females with a mean age of 45.7 years. Orbital fractures were most common (41.2%), followed by maxilla fractures (20.8%). The most common mechanism was fall (43.0%). Surgical management was recommended for 41% of patients. The odds of surgical management was significantly lower in female patients, patients age 65 and older, and patients who presented after the onset of the COVID-19 pandemic. The odds of surgical management was significantly higher for patients who had a mandible fracture or greater than 1 fracture. The average cost of management was highest for naso-orbito-ethmoidal fractures ($37,997.74 ± 52,850.88), followed by LeFort and frontal fractures ($29.814.41 ± 42,155.73 and $27,613.44 ± 39.178.53, respectively). The highest contributor to the total average cost of management was intensive care unit-related costs for every fracture type, except for mandible fractures for which the highest contributor was operating room (OR)-related costs.

CONCLUSIONS

This study represents one of the largest comprehensive databases of facial fractures and one of the first to provide a descriptive cost analysis of facial trauma management.

LEVEL OF EVIDENCE

Risk Factors for Missed Follow-up Appointments among Facial Trauma Patients

A retrospective case-control study was performed to characterize the rate of missed follow-up appointments after facial trauma and identify associated risk factors.Follow-up appointments for facial trauma over a 3-month period at a single, safety net hospital were analyzed. Appointment-specific, sociodemographic, trauma, and management data were compared between cases (missed appointments) and controls (attended appointments). Univariate testing and multivariable logistic regression were employed.A total of 116 cases and 259 controls were identified, yielding a missed appointment rate of 30.9% (116/375). Missed appointments were significantly associated with initial clinic appointments compared to return visits (odds ratio [OR] 2.21 [1.38-3.54]), afternoon visits compared to morning (OR 3.14 [1.94-5.07]), lack of private health insurance (OR 2.91 [1.68-5.18]), and presence of midface fractures (OR 2.04 [1.28-3.27]). Missed appointments were negatively associated with mandible fractures (OR 0.56 [0.35-0.89]), surgical management (OR 0.48 [0.30-0.77]), and the presence of nonremovable hardware (OR 0.39 [0.23-0.64]). Upon multivariable logistic regression, missed appointments remained independently associated with afternoon visits (adjusted OR [aOR] 1.95 [1.12-3.4]), lack of private health insurance (aOR 2.73 [1.55-4.8]), and midface fractures (aOR 2.09 [1.21-3.59]).Nearly one-third of facial trauma patients missed follow-up appointments, with the greatest risk among those with afternoon appointments, lacking private health insurance, and with midface fractures.

The Role of Orthodontics in the Management of Maxillofacial Fractures in Children: A Review on Contemporary Approaches

Maxillofacial fractures present complex challenges requiring effective orthodontic management to restore function and aesthetics. This review explores various orthodontic techniques, including fixed braces, maxillomandibular fixation (MMF), functional orthodontic therapy (FOT), and acrylic splints, emphasizing their roles in stabilizing fractures and promoting healing. The management of condylar fractures is discussed, highlighting the benefits of early intervention with functional appliances to facilitate condylar remodeling in children and adolescents. Additionally, the review covers splinting methods for dental and dentoalveolar fractures and the use of open reduction internal fixation (ORIF) for maxillary fractures. It addresses the complications and challenges of fracture management, the need for a multidisciplinary approach, and the limitations of current studies. Future directions include the use of advanced technologies such as virtual surgical planning (VSP) and 3D printing to enhance treatment precision and outcomes. This review provides a comprehensive overview of orthodontic strategies for maxillofacial fractures, offering insights into clinical applications and future advancements.

Interfacility Transfer Guidelines for Patients With Isolated Facial Trauma-From Problem to Solution

This Viewpoint discusses the need to implement proposed guidelines for facial trauma assessment to prevent unnecessary interfacility transfer of patients with facial trauma despite most such patients having injuries that do not require surgical intervention.

Global, regional, national trends of femur fracture and machine learning prediction: Comprehensive findings and questions from global burden of disease 1990-2019

Background

Femur fracture is a type of fracture with high disability and mortality. There is no comprehensive analysis and prediction of the global distribution of femur fractures, so we conducted this study.

Methods

Age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), and years living with disability (YLDs) of femur fractures (excluding femoral neck) were downloaded from the Global burden of disease database. Trend analysis was performed, and 6 time-series machine learning algorithms were applied to predict the global ASIR, ASPR, and YLDs.

Results

ASPR for femur fracture had been increasing in most countries worldwide from 1990 to 2019, with the highest in East Asia (AAPC = 1.25 95%Confidence Interval (1.2, 1.3)) and lowest in Central Latin America (AAPC = -0.74 95%CI (-0.81, -0.67)). However, ASIR showed a significant downward trend worldwide, with East Saharan Africa decreasing the most (AAPC = -4.04 95%CI (-5.56, -2.47)), and East Asia elevating the most (AAPC = 1.11 95%CI (0.87, 1.42)). YLDs were increasing over the world, with East Asia still elevating the most AAPC= (3.9 95%CI (3.85, 3.95)), with the only region of decrease being Eastern Europe (AAPC = -0.28 95%CI (-0.3, -0.26)). Both ASPR and ASIR were higher in women than in men in the >75 year group, whereas YLDs was lower in women than in men in the >60 year group. Globally, the ARIMA model was optimal in the prediction of ASPR, the PROPHET model effected in the prediction of ASIR, and the PROPHET WITH XGBOOST model was the best in the prediction of YLDs. The projections showed increase in both ASPR and YLDs, except for ASIR decreasing by 2030.

Conclusions

Our study found a rise in femur fracture ASPR and ASIR from 1990 to 2019 in war conflict areas and East Asia, meanwhile, the YLDs of femur fracture increased in populous countries. In both 1990 and 2019, both ASPR and ASIR were higher in women over 75 years than that in men, but YLDs was higher in men over 60 years than that in women. In 2020-2030, while global femur fracture ASIR might decline, both ASPR and YLDs might rise.

The Translational Potential of this article

Femur fracture is a high-energy injury due to direct violence, and in war, conflicting and underdeveloped regions such as East Asia. Accidental injuries may occur due to the rapid development of industry and the frequent traffic accidents. This study suggests that we should focus on elderly women (≥75 years) in the above regions in the future. For older men (>60 years old), more attention should be paid to post-fracture functional rehabilitation and early reintegration into society to reduce the disability rate and lower the socio-economic burden.

Enhancing Cranio-Maxillofacial Fracture Care in Low- and Middle-Income Countries: A Systematic Review

Background: Cranio-maxillofacial (CMF) injuries represent a significant challenge in low- and middle-income countries (LMICs), exacerbated by inadequate infrastructure, resources, and training. This systematic review aims to evaluate the current strategies and solutions proposed in the literature to improve CMF fracture care in LMICs, focusing on education, patient transfer, and off-label solutions. Methods: A comprehensive literature search was conducted using PubMed/Medline from January 2000 to June 2023. Studies were selected based on the Preferred Reporting Items for Systematic Review and Meta-analysis Statement (PRISMA). Solutions were categorized into three main areas: education (digital and on-site teaching, fellowships abroad), patient transfer to specialized clinics, and off-label/non-operative solutions. Results: Twenty-three articles were included in the review, revealing a consensus on the necessity for enhanced education and training for local surgeons as the cornerstone for sustainable improvements in CMF care in LMICs. Digital platforms and on-site teaching were identified as key methods for delivering educational content. Furthermore, patient transfer to specialized national clinics and innovative off-label techniques were discussed as immediate solutions to provide quality care despite resource constraints. Conclusions: Effective CMF fracture care in LMICs requires a multifaceted approach, prioritizing the education and training of local healthcare professionals, facilitated patient transfer to specialized centers, and the adoption of off-label solutions to leverage available resources. Collaborative efforts between international organizations, local healthcare providers, and educational institutions are essential to implement these solutions effectively and improve patient outcomes in LMICs.

Global, regional, and national burdens of facial fractures: a systematic analysis of the global burden of Disease 2019

BACKGROUND

The incidence of facial fractures has undergone tremendous changes in recent years as a result of socio-economic development and aging populations. Currently, there is a lack of updated and comprehensive analyses of global trends and causes of facial fractures. The Global Burden of Disease (GBD) database is a product of a global research organization used to quantify the global impact of hundreds of diseases, injuries, and risk factors. The aim of this study was to update global burden of facial fractures from 1990 to 2019 by using the GBD2019.

MATERIALS AND METHODS

The present study extracted the global incidence, prevalence, and years lived with disability (YLDs) for facial fractures, as well as the age-standardized rates (ASRs) of these variables using the Global Burden of Disease (GBD) 2019 database. The estimated annual percentage change (EAPC) was used to assess the trends of ASRs.

RESULTS

Between 1990 and 2019, the incidence of facial fractures increased from 8,943,707 to 10,676,340, but the age-standardized incidence rate (ASIR) decreased from 161.5 to 138.8 per 100,000. Prevalence and YLDs exhibited the same trend as incidence. Over the 30 years, the incidence of facial fractures was consistently greater in males than in females. However, females aged ˃ 75 years had higher fracture incidence rates than males aged ˃ 75 years in 2019. The leading cause of facial fractures was falls, and both the age-standardized prevalence rate (ASPR) and age-standardized years lived with disability rate (ASYR) of falls increased with age.

CONCLUSION

Facial fractures still represent a significant burden to the world. Incidence, prevalence and YLDs all showed increasing trends, while ASRs decreased gradually from 1990 to 2019. Enhancing the quality of facial fractures data is helpful for monitoring the burden of facial fractures.

Effect of augmented reality-based rehabilitation of hand burns on hand function in children: A randomized controlled trial

BACKGROUND

Despite the use of traditional rehabilitation methods, hand function may still remain impaired in children suffering from burn injuries.

PURPOSE

This study aimed to assess the impact of implementing an augmented reality (AR) rehabilitation booklet designed for pediatric hand burn on their hand functionality.

STUDY DESIGN

This was a randomized controlled trial.

METHODS

Seventy-two children, aged 8-14 years with a hand burn, were randomly allocated into intervention (n = 36) and control (n = 36) groups. Children in the control group received routine rehabilitation program, while in the intervention group, children performed exercises using a printed booklet with related AR application. The Jebsen-Taylor Hand Function Test was completed before the intervention at the time of the patients' discharge and 1 month later.

RESULTS

The results of analysis of covariance based on baseline- and fully-adjusted models showed significant intervention effect after discharge as well as after intervention for hand function (mean difference [95% confidence interval] for discharge: -8.2 [-15.0 to -1.4] and for after intervention: -74.0 [-88.8 to -59.1]) and the items (all p < 0.05), except for writing and lifting large light objects for both after discharge and after intervention measures (all p-value > 0.05).

CONCLUSIONS

A significant decrease in the total time taking to complete the Jebsen-Taylor hand function test was observed in the intervention group compared to the control group 1 month after discharge. Rehabilitation of children with hand burns, using printed educational booklet with related AR application, improves their hand function.

Have Incidence and Severity of Craniomaxillofacial Fractures Changed Since SARS-CoV-2?

BACKGROUND

An increase in severity and a decrease in incidence of craniomaxillofacial fractures (CMFs) were identified during the first several months of the SARS-CoV-2 pandemic. It is unclear if these changes have persisted in the current timeframe.

PURPOSE

The investigators hypothesize that the incidence and severity of CMF will not return to baseline prepandemic (control) levels as the pandemic stabilizes and becomes endemic.

STUDY DESIGN, SETTING, SAMPLE

This retrospective cohort study enrolled subjects who presented to Harborview Medical Center a Level 1 trauma center for the evaluation and management of CMF. Inclusion criteria were 1) Presentation timeline 2018 through 2022, 2) CMF identified by the 10th International Classification of Disease. Exclusion criteria were: 1) Undocumented etiology of facial fracture and 2) inadequate/unclear documentation otherwise.

PREDICTOR/EXPOSURE/INDEPENDENT VARIABLE

The predictor variable was year of injury relating to the start of the pandemic. The groups were the prepandemic (2018, 2019) and postpandemic (2020, 2021. 2022).

MAIN OUTCOME VARIABLES

The primary outcome variable was the CMF diagnosis identified using the corresponding International Classification of Disease, 10th Edition codes. The secondary outcome variables were mechanism of injury and injury severity.

COVARIATES

The covariates were age, sex, race/ethnicity, admission status, alcohol intoxication, toxicology screen, reimbursement source, abuse reported, and abuse investigated.

ANALYSES

Univariate and bivariate analyses were performed with statistical significance at P < .05.

RESULTS

The sample was composed of 5203 subjects. The annual volumes of subjects presenting with CMF were consistent over the study period (2018, 2019, 2020, 2021, 2022 n = 1018, 963, 1020, 1062, 1140, respectively). The incidence of Hispanics increased (2018, 2019, 2020, 2021, 2022: 11.1, 9.6, 12.2, 13.9, 13.2% (P < .05)) as did firearm CMF injuries (2018, 2019, 2020, 2021, 2022: 4.13, 4.98, 4.71, 7.16, 6.75% (P < .05)). The Injury Severity Score and Abbreviated Injury Scale were both lower postpandemic compared to prepandemic; mean Injury Severity Score post [18.27 ± 12.46] versus pre [19.25 ± 12.89] (P < .05), mean Abbreviated Injury Scale post [2.94 ± 1.15] versus pre [3.04 ± 1.14] (P < .05).

CONCLUSIONS AND RELEVANCE

While the severity of CMF decreased postpandemic, Hispanic and firearm CMF increased. The overall CMF incidence remained the same. The significant rise in firearm injuries warrants further study.

Development of AI-Based Diagnostic Algorithm for Nasal Bone Fracture Using Deep Learning

Facial bone fractures are relatively common, with the nasal bone the most frequently fractured facial bone. Computed tomography is the gold standard for diagnosing such fractures. Most nasal bone fractures can be treated using a closed reduction. However, delayed diagnosis may cause nasal deformity or other complications that are difficult and expensive to treat. In this study, the authors developed an algorithm for diagnosing nasal fractures by learning computed tomography images of facial bones with artificial intelligence through deep learning. A significant concordance with human doctors' reading results of 100% sensitivity and 77% specificity was achieved. Herein, the authors report the results of a pilot study on the first stage of developing an algorithm for analyzing fractures in the facial bone.

Global burden of hip fracture: The Global Burden of Disease Study

This study is the first to measure global burden of hip fracture in patients aged 55 years and older across 204 countries and territories from 1990 to 2019. Our study further proved that the global burden of hip fracture is still large. Hip fractures among males are perhaps underestimated, and older adults should be given more attention.

PURPOSE

Hip fracture is a tremendous universal public health challenge, but no updated comprehensive and comparable assessment of hip fracture incidence and burden exists for most of the world in older adults.

METHODS

Using data from the Global Burden of Diseases (GBD) 2019, we estimated the number and rates of the incidence, prevalence, and years lived with disability (YLD) of hip fracture across 204 countries and territories in patients aged 55 years and older from 1990 to 2019.

RESULTS

In 2019, the incidence, prevalence, and YLDs rates of hip fracture in patients aged 55 years and older were 681.35 (95% UI 508.36-892.27) per 100000 population, 1191.39 (95% UI 1083.80-1301.52) per 100000 population, and 130.78 (95% UI 92.26-175.30) per 100000 population. During the three decades, the incidence among people aged below 60 years showed a downward trend, whereas it showed a rapid upward trend among older adults. All the numbers and rates of hip fractures among females were higher than those among males and increased with age, with the highest number and rate in the highest age group. Notably, the male to female ratio of the incidence for people aged over 55 years increased from 0.577 in 1990 to 0.612 in 2019. Falls were the leading cause among both sexes and in all age groups.

CONCLUSIONS

The incidence and the number of hip fractures among patients aged 55 years and older increased over the past three decades, indicating that the global burden of hip fracture is still large. Hip fractures among males are perhaps underestimated, and older adults should be given more attention.

Caring for the Patient with Otolaryngologic Trauma Is a Complex Matter

In an Austrian study of 14,654 patients with 35,129 injuries treated at a single Department of Cranio-Maxillofacial and Oral Surgery over a 15-year period, the following was seen.1 Older people were more prone to soft tissue lesions with a rising risk of 2.1% per year older, equal in men and women. Younger patients were at higher risk of dentoalveolar trauma with an increase of 4.4% per year younger, and this was 19.6% higher for women. The risk of sustaining facial bone fractures increased each year by 4.6% and was 66.4% times higher in men. A total of 2550 patients (17.4%) suffered 3834 concomitant injuries of other body parts.

Bioactive Scaffolds as a Promising Alternative for Enhancing Critical-Size Bone Defect Regeneration in the Craniomaxillofacial Region

Reconstruction of critical-size bone defects (CSDs) in the craniomaxillofacial (CMF) region remains challenging. Scaffold-based bone-engineered constructs have been proposed as an alternative to the classical treatments made with autografts and allografts. Scaffolds, a key component of engineered constructs, have been traditionally viewed as biologically passive temporary replacements of deficient bone lacking intrinsic cues to promote osteogenesis. Nowadays, scaffolds are functionalized, giving rise to bioactive scaffolds promoting bone regeneration more effectively than conventional counterparts. This review focuses on the three approaches most used to bioactivate scaffolds: (1) conferring microarchitectural designs or surface nanotopography; (2) loading bioactive molecules; and (3) seeding stem cells on scaffolds, providing relevant examples of in vivo (preclinical and clinical) studies where these methods are employed to enhance CSDs healing in the CMF region. From these, adding bioactive molecules (specifically bone morphogenetic proteins or BMPs) to scaffolds has been the most explored to bioactivate scaffolds. Nevertheless, the downsides of grafting BMP-loaded scaffolds in patients have limited its successful translation into clinics. Despite these drawbacks, scaffolds containing safer, cheaper, and more effective bioactive molecules, combined with stem cells and topographical cues, remain a promising alternative for clinical use to treat CSDs in the CMF complex replacing autografts and allografts.

A meta-analysis to evaluate the prevalence of maxillofacial trauma caused by various etiologies among children and adolescents

AIMS

Children and adolescents who are affected by trauma may have complications that are more serious and dangerous. Herein, a meta-analysis to evaluate the prevalence of maxillofacial trauma caused by various etiologies according to the geographic regions of the world among children and adolescents was conducted.

MATERIALS AND METHODS

A comprehensive search was performed in four databases of PubMed/MEDLINE, Web of Science, Cochrane Library, and Scopus from January 1, 2006 until July 7, 2021. To evaluate the quality of included articles, an adapted version of the Newcastle-Ottawa scale was used. The prevalence of maxillofacial trauma was estimated by event rates and 95% confidence intervals in relation to etiology and geographic region of study population.

RESULTS

Through search in the databases and the electronic sources, 3071 records were identified, and 58 studies were eligible for inclusion in the meta-analysis. A total of 264,433 maxillofacial trauma cases were reported by all included studies. Globally, the overall prevalence of maxillofacial trauma was highest due to Road Traffic Crashes (RTC) (33.8%) followed by falls (20.7%), violence (9.9%), and sports (8.1%) in children/adolescents. The highest prevalence of maxillofacial trauma were observed in African population (48.3%) while trauma due to falls was most prevalent in Asian population (44.1%). Maxillofacial trauma due to violence (27.6%) and sports (13.3%) were highest in North Americans.

CONCLUSION

The findings demonstrate that RTC was the most prevalent etiology of maxillofacial trauma in the world. The prevalent causes of maxillofacial trauma differed between the regions of study population.

Predictors of Facial Fractures in Trauma Patients: Retrospective Review at a Level I Trauma Center

BACKGROUND

The incidence and causes of facial fractures differ between patients, but patterns arise within populations. These patterns vary by gender, age, and between countries. This study aims to determine variables to identify patients at risk for facial fractures in a United States trauma population.

METHODS

This is a single-center study of Trauma Registry data, inclusive of years July 1, 2016, to January 31, 2022. Inclusion criteria were based upon all trauma patients. Confirmation of a non-isolated facial fracture (dependent variable) was verified using ICD10 diagnosis codes. A logistic regression was performed in SPSS to ascertain the effects of predictor variables on the likelihood that a trauma patient will experience a facial fracture.

RESULTS

20377 patients were included in the analysis based upon the requirements specified in the methods section; 1575 (7%) had a positive facial fracture. The logistic regression model was statistically significant (N = 18507, P < .01). Significant risk factors for facial fracture identified included helicopter transport (OR = 1.35, P < .01) and increasing injury severity scores (OR = 1.07, P < .01). Modes of injury most likely to predict facial fracture included assault (OR = 6.62, P < .01), moped (OR = 2.02, P < .01), and motorcycle trauma (OR = 1.55, P < .01). The discharge disposition most likely among facial fracture patients included short-term general hospital (OR = 1.71, P < .01) and intermediate care facility (OR = 4.47, P < .01).

CONCLUSIONS

Patients with traumatic injuries from assault, moped, and motorcycle accidents were more likely to present with facial fractures. These patients had more severe injuries, seen as increased ISS scores, higher likelihood of transport by helicopter, and the need for additional care after discharge.

A RETROSPECTIVE STUDY OF THE MAXILLOFACIAL INJURIES IN TWO EMERGENCY DEPARTMENTS IN TBILISI, GEORGIA

Maxillofacial injuries are a global problem in our modern society. It can be a major cause of increased morbidity and mortality. Maxillofacial trauma can lead to scar distortion accompanied by emotional and psychological problems. The epidemiology of facial fractures varies in terms of trauma type, the extent of injury, and severity. The main aim of this research is to explore the scope, the burden, and the etiology of maxillofacial injuries in Tbilisi, Georgia. Data was retrospectively collected from two large emergency departments in Tbilisi, Georgia using a cross-sectional design. Inclusion criteria was patients admitted in hospitals during one year with diagnosis maxillofacial injury. SPSS 21 software was used for statistical analysis. Differences in categorical variables were assessed with Chi-square tests of independence. This research shows that men are still the most frequent victims of maxillofacial injuries. Out of 598 patients, whose age ranged from 1month to 87 years - 67% were males, and 33% patients were females, including both, maxillofacial trauma alone and also combined injuries. With only maxillofacial injuries, the male patients were still leading, with 51% (307) and female patients were 28% (167), these results gave us a statistically significant difference (p=0.026). The main causes of maxillofacial injuries were falls, which equaled to 63% (378 patients) from total recorded data, as in many other countries. The results of this research provide really important information about future preventive interventions in the country. It also shows us that educating the public with prevention strategies is substantial.

Epidemiology of maxillofacial fractures in northwest China: an 11-year retrospective study of 2240 patients

BACKGROUND

The aim of this study was to determine the epidemiological pattern of maxillofacial fractures in northwestern China by retrospectively analysing the demographics, aetiologies, concomitant injuries, fracture sites, and management.

METHODS

A 10-year retrospective analysis of 2240 patients with maxillofacial fractures admitted to the General Hospital of Ningxia Medical University was conducted. The extracted data included sex, age, aetiology, fracture site, concomitant injuries, time of treatment, therapeutic approaches and complications. Statistical analyses were performed, including descriptive analysis and the chi-square test. Logistic regression was used to determine the impact factors of maxillofacial fractures and concomitant injuries. P values < 0.05 were considered statistically significant.

RESULTS

The age of the included patients ranged from 1 to 85 years, and the mean age was 35.88 ± 15.69 years. The male-to-female ratio was 3.9:1. The most frequent aetiology of maxillofacial fractures was road traffic accidents (RTAs) (56.3%), and the most common fracture sites were the anterior wall of the maxillary sinus, arcus zygomaticus and mandibular body. A total of 1147 patients (51.2%) were affected by concomitant injuries, with craniocerebral injury being the most common. Logistic regression analyses revealed increased risks of mid-facial fractures in elderly individuals (odds ratio (OR) = 1.029, P < 0.001) and females (OR = 0.719, P = 0.005). Younger patients had a higher risk of mandibular fractures (OR = 0.973, P < 0.001). RTAs increased the risk for mid-facial fractures and high falls increased the risk for mandibular fractures.

CONCLUSIONS

The maxillofacial fracture pattern is correlated with sex, age and aetiology. Patients were mainly young and middle-aged males, and the main cause of injury was RTAs, mostly causing compound fractures. Medical staff must be systematically educated to comprehensively examine patients with injuries resulting from RTAs. The management of patients with fractures requires thorough consideration of the patient's age, aetiology, fracture site, and concomitant injuries.

Clinical Patterns and Treatment of Pediatric Facial Fractures: A 10-Year Retrospective Romanian Study

Pediatric facial fractures have different clinical patterns and require different therapeutic approaches in comparison with those of facial fractures that occur among adults. The aim of this study was to describe the main clinical characteristics of pediatric facial fractures (such as fracture location, fracture pattern, treatment, complications and evolution) in a group of pediatric patients from NW Romania. This research was a retrospective study that was conducted for 10 years in a tertiary hospital for oral and maxillofacial surgery from NW Romania. A total of 142 pediatric patients were included in this study, with ages between 0 and 18 years. Mandibular (66.2%), midface (25.4%) and combined fractures (8.5%) were identified, and patients from the 13-18 years age group were more frequently affected by facial fractures (78.9%). Most of the diagnosed fractures among all three types of fractures were total fractures, and most mandibular (92.6%) and midface (80.6%) fractures were without displacement. Hematomas, lacerations and abrasions were identified as associated lesions. Patients with associated lesions were more frequently associated with combined fractures or midface fractures than mandibular fractures. The instituted treatment was, in general, orthopedic, for all three types of fractures (mandibular-86.2%; midface-91.7%; combined-66.7%). Most fractures, mandibular (96.8%), midface (100%) and combined (91.7%) fractures, had a favorable evolution. Most fractures did not present any complications at the follow-up. Pediatric facial fractures have unique patterns and must be treated with caution, considering the particularities of pediatric facial anatomy.

Imaging of Maxillofacial Trauma

Maxillofacial trauma is common. Computed tomography is the primary imaging tool for diagnosis. Study interpretation is aided by understanding regional anatomy and clinically relevant features of each subunit. Common injury patterns and the most important factors related to surgical management are discussed.

Orthodontic Approaches in the Management of Mandibular Fractures: A Scoping Review

Non-surgical approaches have been proposed in the management of mandibular fractures, especially in children, but there is a lack of clear guidelines on the clinical indications of conservative approaches. The aim of this scoping review is to provide the available evidence of the role of the orthodontist in the management of mandibular fractures. The PRISMA-ScR guidelines were followed to select eligible articles from the PubMed, Scopus, and Web of Science databases according to precise inclusion criteria. The research questions were formulated as follows: "what is the scientific evidence concerning the rule of orthodontists in the management of mandibular fractures" and "the preferential use of the direct bonding technique with orthodontic brackets rather than rigid arch bars"? Seventeen articles were included. Five articles presented the use of removable acrylic splints or functional appliances, six articles concerned the employment of cemented acrylic or rigid splints, and six articles described the management of mandibular fractures in adults and children using orthodontic brackets or mini-screws. Most of these techniques have been employed in children and growing subjects, while fewer data were available regarding conservative treatments in adults. Preliminary evidence suggests that condylar and some minor parasymphyseal fractures in children may be managed with conservative approaches. In adults, minor condylar and stable body mandibular fractures with minimal displacement have been reduced similarly. However, there are no sufficient elements that could suggest the preferential use of orthodontic brackets over rigid arch bars in adults. Further randomized and non-randomized clinical trials with long follow-ups will be needed to better define the clinical indications of the orthodontic approaches in the management of mandibular fractures based on severity, location, and age.

Current Frequency of Mandibular Condylar Process Fractures

There are significant discrepancies in the reported prevalence of condylar process fractures among all mandibular fractures (16.5-56%) in the available literature. In addition, it seems that the actual number of difficult-to-treat fractures of the mandibular head is unknown. The purpose of this study is to present the current incidence of the different types of mandibular process fractures with a special focus on mandibular head fractures. The medical records of 386 patients with single or multiple mandibular fractures were reviewed. Of the fractures found, 58% were body fractures, 32% were angle fractures, 7% were ramus fractures, 2% were coronoid process fractures, and 45% were condylar process fractures. The most common fracture of the condylar process was a basal fracture (54% of condylar fractures), and the second most common fracture was a fracture of the mandibular head (34% of condylar process fractures). Further, 16% of patients had low-neck fractures, and 16% had high-neck fractures. Of the patients with head fractures, 8% had a type A fracture, 34% had a type B fracture, and 73% had a type C fracture. A total of 89.6% of the patients were surgically treated with ORIF. Mandibular head fractures are not as rare as previously thought. Head fractures occur twice as often in the pediatric population than in adults. A mandibular fracture is most likely related to a mandible head fracture. Such evidence can guide the diagnostic procedure in the future.

Epidemiologic Changes of Facial Bone Fracture before and after Coronavirus Disease 2019: A Level 1 Trauma Center in Korea

Background  The coronavirus disease 2019 (COVID-19) outbreak has had a major impact worldwide. Several countries have implemented restrictions on social interaction ("social distancing"). Several studies have reported that the epidemiology of trauma patients, such as those with facial bone fractures, has changed after COVID-19 pandemic. This study aimed to further explore these specific changes. Methods  This was a retrospective study of patients who presented to a single institution with facial bone fractures between January 1, 2016, and December 31, 2020. Baseline patient demographics, clinical information, type of fracture, etiology, and operative management were compared before and after COVID-19. Results  Of all cases, 3,409 occurred before COVID-19, and 602 occurred after COVID-19. Since the outbreak of COVID-19, the number of patients with facial fractures has not decreased significantly. A significant increase was noted in fractures that occurred outdoors ( p  < 0.001). However, a decrease was observed in operative management between the groups ( p  < 0.001). There was no significant difference in the proportion of assault, fall-down, industrial accident, or roll-down. In contrast, the proportion of traffic accidents and slip-down categories increased significantly ( p  < 0.05). Moreover, a significant decrease was found in the proportion of the sports category ( p  = 0.001) Conclusions  It was confirmed through this study that COVID-19 pandemic also affected epidemiology of facial fractures. Focusing on these changes, it is necessary to develop safety measures to reduce facial fractures.

Effectiveness of Physical Therapy in Orthognathic Surgery Patients: A Systematic Review of Randomized Controlled Trials

Orthognathic surgery (OS) can present many complications that affect patients' rehabilitation. However, there have been no systematic reviews that assessed the effectiveness of physiotherapy interventions in the postsurgical rehabilitation of OS patients. The aim of this systematic review was to analyze the effectiveness of physiotherapy after OS. The inclusion criteria were randomized clinical trials (RCTs) of patients who underwent OS and who received therapeutic interventions that included any physiotherapy modality. Temporomandibular joint disorders were excluded. After the filtering process, five RCTs were selected from the 1152 initially obtained (two had acceptable methodological quality; three had insufficient methodological quality). The results obtained showed that the effects of the physiotherapy interventions studied in this systematic review on the variables of range of motion, pain, edema and masticatory muscle strength were limited. Only laser therapy and LED showed a moderate level of evidence in the postoperative neurosensory rehabilitation of the inferior alveolar nerve compared with a placebo LED intervention.

Mapping Evidence on the Epidemiology and Cost Associated with Maxillofacial Injury among Adults in Sub-Saharan Africa: A Scoping Review Protocol

(1) Background: Maxillofacial injury (MI) occurs universally, for it disregards preference for age, gender, and geographical region. The global incidence and prevalence of facial fractures rose by 39.45% and 54.39%, respectively, between the years 1990 to 2017. Projections indicate that the burden of injuries will persist in sub-Saharan Africa (SSA) in the next twenty years. This scoping review aims to map the literature on MI epidemiology and the economic burden on society in SSA. (2) Methods: The methodology presented by Arksey and O'Malley and extended by Levac and colleagues will be employed in the scoping review. The researcher will report the proposed review through the Preferred Reporting Items for Systematic Review, and Meta-Analysis extension for scoping reviews (PRISMA-ScR). The review will include studies encompassing MI in sub-Saharan African adults 18 years and above. (3) Results: This will be presented as a thematic analysis of the data extracted from the included studies, and the Nvivo version 12 will be employed. (4) Discussion: We anticipate searching for related literature on the prevalence, incidence, risk factors, mortality, and cost associated with MI in the adult population of SSA. The conclusion from the review will assist in ascertaining research gaps, informing policy, planning, authorizing upcoming research, and prioritizing funding for injury prevention and management.

Bond Strength and Adhesion Mechanisms of Novel Bone Adhesives

Bone adhesives offer distinct advantages over the use of screws to attached internal fixation plates (IFPs). As the chemical composition of bone is similar to dentine, it is possible that the types of monomers used to make dentine adhesives could be utilised to affix IFPs to bone. The ability to attach a bio-resorbable IFP to porcine bone was assessed for the monomer 10-methacryloyloxydecyl dihydrogen phosphate (MDP), used either as a homopolymer or a copolymer with urethane dimethacrylate (MDP + U). Additionally, the addition of a priming step (MDP + U + P) was evaluated. The chemical interactions of the monomers with bone were assessed using XRD and imaged using TEM, revealing the formation of nano-layered structures with the MDP primer, something we believe has not been reported on bone. In a 6-week artificial aging study both MDP + U and MDP + U + P demonstrated adequate shear bond strength to affix bio-resorbable IFPs. The cytotoxicity profiles of the adhesive formulations were determined using indirect and direct contact with MC3T3 cells, with indirect conditions suggesting the MDP + U + P is as cytocompatible as the resorbable IFP. The findings of this study suggest our newly developed adhesive has the potential to be used as a bone adhesive to affix bioresorbable IFPs.

Stair-related falls in the USA: traumatic brain injury and the role of alcohol intoxication

INTRODUCTION

Falls are a leading cause of head injury in the USA. Stair-related fall injuries are common and often more serious than same level falls. Alcohol is a known contributor to unintentional injuries, and often associated with fall-related injuries, specifically falls occurring on stairs. The objective was to examine the association between alcohol use and head injuries (traumatic brain injuries (TBIs) or craniomaxillofacial (CMF) injuries) among persons aged 15-64 presenting to an emergency department (ED) with an injury resulting from a fall on stairs.

METHODS

Using the 2019 National Electronic Injury Surveillance System, US ED records were examined. Injuries due to falling on stairs were retrieved, with the role of alcohol in the outcome of TBI and CMF injuries examined. Prevalence ratios (PR), adjusted for covariates (blood alcohol level screening, patient demographics, drug use, disposition) were obtained from average marginal predictions derived from logistic regression models.

RESULTS

An estimated 687 902 patient visits related to falls on stairs occurred during the study period. Patients who presented with alcohol intoxication had a higher prevalence of TBI (PR 2.7 95% CI 2.3 to 3.1) and CMF injuries (PR 2.5; 95% CI 2.3 to 2.8). PRs were more pronounced among patients with blood alcohol concentration ≥0.1, as was hospital admission.

CONCLUSIONS

Stair-related falls represent a common cause of ED visits for falls in the USA. Alcohol intoxication had a detrimental effect on the prevalence of TBI and CMF. A multimodal treatment approach may be beneficial given the complex interrelationship between the injury type and alcohol.

Methodological considerations in injury burden of disease studies across Europe: a systematic literature review

Background

Calculating the disease burden due to injury is complex, as it requires many methodological choices. Until now, an overview of the methodological design choices that have been made in burden of disease (BoD) studies in injury populations is not available. The aim of this systematic literature review was to identify existing injury BoD studies undertaken across Europe and to comprehensively review the methodological design choices and assumption parameters that have been made to calculate years of life lost (YLL) and years lived with disability (YLD) in these studies.

Methods

We searched EMBASE, MEDLINE, Cochrane Central, Google Scholar, and Web of Science, and the grey literature supplemented by handsearching, for BoD studies. We included injury BoD studies that quantified the BoD expressed in YLL, YLD, and disability-adjusted life years (DALY) in countries within the European Region between early-1990 and mid-2021.

Results

We retrieved 2,914 results of which 48 performed an injury-specific BoD assessment. Single-country independent and Global Burden of Disease (GBD)-linked injury BoD studies were performed in 11 European countries. Approximately 79% of injury BoD studies reported the BoD by external cause-of-injury. Most independent studies used the incidence-based approach to calculate YLDs. About half of the injury disease burden studies applied disability weights (DWs) developed by the GBD study. Almost all independent injury studies have determined YLL using national life tables.

Conclusions

Considerable methodological variation across independent injury BoD assessments was observed; differences were mainly apparent in the design choices and assumption parameters towards injury YLD calculations, implementation of DWs, and the choice of life table for YLL calculations. Development and use of guidelines for performing and reporting of injury BoD studies is crucial to enhance transparency and comparability of injury BoD estimates across Europe and beyond.

Clinical application of cinematic rendering in maxillofacial fractures

The purpose of this study was to evaluate the clinical application of cinematically rendered reconstructions of maxillofacial fractures. Ten surgeons and eight radiologists were shown three-dimensional images of 25 different patient cases, generated using both the volume rendering (VR) technique and the cinematic rendering (CR) technique. They were asked to mark the site of the fracture on the three-dimensional images and record the time this activity took. The effectiveness of the reconstructions to communicate with patients was assessed through the opinions of the surgeons and radiologists, as well as 25 patients. Subjective evaluations of the clinical value of the images were performed by the 18 surgeons and radiologists using a 10-item questionnaire. The percentages of correctly identified fractures of the nasal bone (P = 0.034), fracture dislocation (P < 0.001), and free bone fragments (P < 0.001) were significantly higher for CR images when compared to VR images, and identification took an average of 20.81 seconds for CR and 27.48 seconds for VR (P < 0.001). CR images were found to be more beneficial for communication with patients and scored higher for the display of fracture dislocation and free bone fragments than VR images (P < 0.05). CR images were found to have high clinical value in the visualization of maxillofacial fractures.

Demographic Discrepancies of Vitamin D Deficiency in Craniofacial Fracture Patients

Background

The relationship between craniofacial fracture and vitamin D status has not been studied. Given the important role vitamin D status plays in postfracture prognosis, a deep investigation into this relationship is due. The primary objective of this study was to assess the demographic discrepancies in the vitamin D status of patients with craniofacial fracture.

Methods

The Cerner Health Facts database was used to collect data on serum 25-hydroxyvitamin D, demographics, hospital admission and discharge, and fracture type of 76 craniofacial fracture patients with available vitamin D levels from October 2015 until May 2018. Pairwise Spearman Correlation was used for multivariate data analysis.

Results

Of the 76 craniofacial fracture patients identified, 55.3% were insufficient in vitamin D and 32.9% were deficient in vitamin D. Vitamin D deficiency and insufficiency were more common in women, African American individuals, and patients over 50 years of age.

Conclusions

The investigation revealed a high prevalence of vitamin D deficiency and insufficiency in craniofacial fracture patients. Despite the higher incidence of fractures in men and Caucasian individuals, women and African American individuals with craniofacial fractures had poorer vitamin D status. Clinicians should consider empiric vitamin D supplementation following craniofacial fracture in high-risk groups.

The Incidence and Risk Factors of Medial and Inferior Orbital Wall Fractures in Korea: A Nationwide Cohort Study

Purpose: We aimed to investigate orbital wall fracture incidence and risk factors in the general Korean population. Method: The Korea National Health Insurance Service–National Sample Cohort dataset was analyzed to find subjects with an orbital wall fracture between 2011 and 2015 (based on the diagnosis code) and to identify incident cases involving a preceding disease-free period of 8 years. The incidence of orbital wall fracture in the general population was estimated, and the type of orbital wall fracture was categorized. Sociodemographic risk factors were also examined using Cox regression analysis. Results: Among 1,080,309 cohort subjects, 2415 individuals with newly diagnosed orbital wall fractures were identified. The overall incidence of orbital wall fractures was estimated as 46.19 (95% CI: 44.37–48.06) per 100,000 person-years. The incidence was high at 10–29 and 80+ years old and showed a male predominance with an average male-to-female ratio of 3.33. The most common type was isolated inferior orbital wall fracture (59.4%), followed by isolated medial orbital wall fracture (23.7%), combination fracture (15.0%), and naso-orbito-ethmoid fracture (1.5%). Of the fracture patients, 648 subjects (26.8%) underwent orbital wall fracture repair surgeries. Male sex, rural residence, and low income were associated with an increased risk of orbital wall fractures. Conclusions: The incidence of orbital wall fractures in Korea varied according to age groups and was positively associated with male sex, rural residency, and low economic income. The most common fracture type was an isolated inferior orbital wall fracture.

Epidemiology of maxillofacial injuries in "Heratsi" No 1 university hospital in Yerevan, Armenia: a retrospective study

Background

The aim of this study was to perform a retrospective analysis of the prevalence, etiologies, types of maxillofacial injuries (MFIs), sites of maxillofacial fractures (MFFs) and their management in Yerevan, Armenia.

Methods

A retrospective cross-sectional study was conducted. The extracted data included age, sex, date of referral, mode of injury, etiology, radiology records and treatment methods. Study outcomes were measured using percentages, means, standard deviations and tests of proportions. P < .05 was considered significant.

Results

A total of 204 patients had a mean age of 36.26 ± 1.08 years (156 males and 48 females), and a total of 259 MFIs were recorded between 2017 and 2020. Interpersonal violence was found to be the most common etiology of MFFs in this study (42.1%), followed by road traffic accidents (RTAs) (27.9%) and falls (18.6%). The nasal bone was the most common injury site (47.5%), followed by the mandible (31.4%) and zygomatic complex (11.7%). The most common fracture site was the mandibular angle (37.9%), followed by the symphysis/parasymphysis (28.1%) and body (12.6%). Isolated soft tissue injuries were reported in 5.9% of the cases. The majority of MFFs were treated by open reduction and internal fixation.

Conclusion

Interpersonal violence, followed by RTAs and falls, was the most common cause of MFIs. Males in the 21–30 years age group had the highest MFI incidence rate. The nasal bone was the most common injury site, followed by the mandible and zygomatic complex. Social education with the objective of reducing aggression and interpersonal conflict should be improved, and appropriate RTA prevention strategies should be strengthened and implemented.

Do Orbital Implants Differ in Complication Rates: A Retrospective Study of 88 Patients, and an Argument for Cost-Effective Practices in the Face of Rising Health Care Costs

Operative repair of orbital fractures utilizes implants constructed of a plethora of materials that vary in cost. Surgeon preference as well as fracture complexity may dictate the implant chosen. In this study, we retrospectively compared the complication rates of the four most common types of implants utilized at our institution. We found no significant difference in complication rates in our sample of 88 patients. Additionally, the least expensive implant was as effective as the most expensive implant in addressing isolated orbital blowout fractures. This situation is not unique to the field of oculoplastics. As evidenced from published literature in other areas of surgery, from orthopaedics to orthodontics, cheaper alternatives often afford similar outcomes as more expensive options. We herein argue that a cost-effective approach should be considered while still allowing for high quality of care, in the face of rising health care costs and health disparities in America.

Postoperative Computed Tomography for Facial Fractures

In order for a radiologist to create reports that are meaningful to facial reconstructive surgeons, an understanding of the principles that guide surgical management and the hardware employed is imperative. This article is intended to promote efficient and salient reporting by illustrating surgical approaches and rationale. Hardware selection can be inferred and a defined set of potential complications anticipated when assessing the adequacy of surgical reconstruction on postoperative computed tomography for midface, internal orbital, and mandible fractures.

Pediatric Facial Fractures in South Australia: Epidemiology, Clinical Characteristics, and Outcomes

INTRODUCTION

Facial fractures of children are relatively infrequent compared to adults. There are variations in facial fractures depending on the socioeconomic, cultural, and educational factors of the country and time. Our aim is to describe epidemiological trends of facial fractures in the pediatric population, understand differences amongst the age groups, and the impact this has on clinical outcomes and management in South Australia.

METHODS

A retrospective review was conducted from January 2012 to January 2017 at the Women and Children's Hosptial, Adelaide. All facial fractures of children, aged 16 years and below, that attended or were referred to the unit were included in this study.

RESULTS

A total of 265 pediatric patients presented with a facial fracture with a male predominance. Some 49.1% occurred from a sports-related injury with bicycle motocross as the single most common type of sport. The mandible was the common fracture type with 21.9% of the total cohort having an associated injury. There were significant differences between boys and girls for age, age groups, mechanism of injury, and type of sport (P < 0.05). Boys were 2.3 times more likely to have a sport-related facial fracture than girls. Early adolescence were 5.2 times more likely to have an orbitozygomatic fracture than children of early childhood (P < 0.05). Age, associated injuries, and sport-related facial fractures were independently associated with increased length of stay (P < 0.001).

CONCLUSIONS

There are differences amongst boys and girls and an understanding of these differences can aid the diagnosis and management in a growing child's face.

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.

Treatment costs of mandibular fractures in a Nigerian hospital

PURPOSE

To determine the cost of surgically treated mandibular fractures, methods of payments, and the relationship between socioeconomic status of subjects and payment methods in a Nigerian tertiary hospital.

METHODS

A retrospective review of 100 subjects who sustained 148 isolated mandibular fractures was conducted between November 2014 and October 2019. Demographics, socioeconomic status, mechanism of injury, fracture sites, type of treatment, and cost of treatment with methods of payments were obtained from medical records and hospital billing sheets of eligible subjects. The relationship between independent variables (age, sex, payment method, and treatment methods) and dependent variable (income class) was analyzed.

RESULTS

The mean age of the subjects was 31.8 ± 10.9 years; age range 17-63 years. The majority (75/100) belonged to the middle-income class. The costs of mandibular fractures repairs were ₦42,900 ($119.17) and ₦132,500 ($386.05) for closed reduction (CRMMF) and open reduction and rigid internal fixation (ORIF) respectively. All subjects in the low-income class (4/100) paid out of pocket for their treatment compared with 93% and 62% of the middle- and high-income classes respectively (p = 0.001). Half of the subjects in the low-income class had ORIF compared with 31% and 62% of the middle- and high-income classes respectively.

CONCLUSIONS

The treatments costs of mandibular fractures were ₦42,900 ($119.17) and ₦132,500 ($386.05) for CRMMF and ORIF respectively. The treatment costs were mostly out-of-pocket expenditure meaning that the subjects in the low-and middle-income classes bore the financial burden of their injuries.
