Epidemiology of Maxillofacial Fractures at a Teaching Hospital in Malaysia: A Retrospective Study

Dental and Maxillofacial Trauma Skills Content in the Southeast Asian Dental Curricula: A Mixed Methods Study

BACKGROUND/AIM

This study aims to review contents related to dental maxillofacial trauma (DMT) in the dental curricula of Southeast Asian (SEA) countries and assess their effectiveness in equipping future dental professionals with the necessary skills for the efficient management of DMT. Additionally, the study aims to describe how the academics involved in the planning and organization of these curricula envision the incorporation of DMT within dental education.

METHODS

The study employed a mixed methods approach composed of two phases. Phase 1 involved a review of all printed documentation to explore the DMT curricula, including details such as the country, subject, year of study, coverage, time spent on the subject, assessment types and various training themes (e.g., management, surgical, prevention). In Phase 2, semi-structured interviews were conducted with academics responsible for curriculum development in each school to identify how they envisaged the incorporation of DMT into the curricula.

RESULTS

Regarding curricular contents, the dataset comprised a total of 31 subjects concerning DMT contents. Findings revealed variability in the coverage of trauma education across institutions, a lack of practical training and the need for better integration and collaboration among different dental specialties. The narrative highlighted concerns about the insufficient hands-on practice available for training in managing DMT, suggesting that students may not have enough opportunities for practical experience in this area. This deficit could potentially impact their ability to effectively manage trauma cases in a clinical setting.

CONCLUSION

This study provides valuable insights into the current state of dental trauma education in SEA countries, identifying critical areas for improvement and potential strategies for enhancing curriculum effectiveness. It emphasizes the importance of integrating practical training and collaborative learning to better equip future dental professionals for trauma management, thereby addressing significant challenges faced by dental educators and practitioners in SEA.

The prevalence of helmet use in motorcyclists around the world: a systematic review and meta-analysis of 5,006,476 participants

Road traffic injuries present a significant public health burden, especially in developing countries. This systematic review and meta-analysis synthesized global evidence on motorcycle helmet use prevalence by including 299 records across 249 articles involving 5,006,476 participants from 1982 to 2022. The findings revealed a declining trend in helmet use prevalence over the past four decades, with an overall prevalence of 48.71%. The meta-regression analysis did not find any statistically significant change in the overall prevalence. Subgroup analysis showed higher helmet use prevalence in observation/survey records (54.29%) compared to crashed patient records (44.84%). Riders/Motorcyclists demonstrated a higher likelihood of wearing helmets than passengers in both observation/survey records (62.61 vs. 28.23%) and crashed patient records (47.76 vs. 26.61%). Countries with mandatory helmet use laws had higher helmet usage prevalence compared to those without (52.26 vs. 37.21%). The African continent had the lowest helmet use rates, while Latin America and the Caribbean regions had higher rates. This study provides a comprehensive overview of global helmet use prevalence, emphasizing disparities between high and low-income countries, variations in law enforcement, and trends over four decades. Targeted interventions are necessary to improve helmet-wearing habits, especially among passengers and regions with low usage rates. Effective legislation and awareness campaigns are crucial for promoting helmet use and reducing road traffic injuries burden.

Comprehensive examination of etiological factors and clinical manifestations of maxillofacial traumas in forensic cases: A five-year retrospective study

BACKGROUND

Maxillofacial injuries, due to their diverse etiological causes, are often considered a component of multi-trauma and constitute a significant portion of trauma. This study aims to elucidate the incidence of maxillofacial traumas, particularly among military personnel, various clinical courses, and characteristics, thereby contributing to the literature.

METHODS

Forensic reports, primarily related to military personnel and organized between 2011 and 2016 at the Forensic Medicine Department of Gülhane Medical Faculty, Health Sciences University, were retrospectively examined. The study involved a detailed analysis of cases with maxillofacial injuries resulting from trauma, focusing on aspects such as age, gender, the origin of the trauma, degree of injury, the presence of bone and dental fractures, and the occurrence of psychiatric disorders as a result of the trauma.

RESULTS

This study demonstrated that maxillofacial traumas predominantly occurred in young male individuals, particularly among military personnel. The most common etiological factor identified was interpersonal violence. The majority of injuries were soft tissue damages, with the nasal bone being the most frequently fractured area. Injuries to the head and upper extremities were also detected in some of the cases, showing that multiple injuries are common in such cases. Post-traumatic psychological disorders developed in some cases, with anxiety disorders being the most commonly observed.

CONCLUSION

It has been determined that maxillofacial injuries can affect multiple body regions, necessitating a multidisciplinary approach. This study underscores the importance of developing comprehensive strategies and policies for understanding and managing maxillofacial traumas, providing a fundamental reference for future studies in this field.

Profile of Facial Trauma Victims of Motorcycle Accidents: A Prospective Study

OBJECTIVE

To outline the profile of patients with facial trauma, victims of motorcycle accidents, treated at the Hospital da Restauração, Recife/PE, Brazil, from December 2020 to July 2021.

METHODS

The collection was carried out through questionnaire and analysis of medical records. Data were analyzed descriptively, as well as Pearson's chi-square test or Fisher's exact test.

RESULTS

Among the patients, 88.6% were male, 47.5% were between 18 and 29 years old, and 59.6% lived in rural areas; 72.15% of the victims used the motorcycle for work and 43.52% were working at the time of the accident. Most victims did not have a national motorcycle license (62%) and were not wearing a helmet at the time of the accident (60%), with 37.6% wearing a full-face helmet, 16.5% an open helmet, and 5.9% an articulated full-face helmet. Soft tissue injuries were the most prevalent. Zygomatic complex fractures were the most common facial fractures and were significantly associated with helmet use and type.

CONCLUSIONS

Most victims of motorcycle accidents are young adult men, without a regular driver's license and residing in rural areas. Preventive and educational actions and continuous traffic inspections are necessary to minimize these accidents.

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.

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.

Chondrocytes supplemented to bone graft-containing scaffolds expedite cranial defect repair

Critical maxillofacial bone fractures do not heal spontaneously, thus, often there is a need to facilitate repair via surgical intervention. Gold standard approaches, include the use of autologous bone graft, or devices supplemented with osteogenic growth factors and bone substitutes. This research aimed to employ a critical size calvaria defect model, to determine if the addition of chondrocytes to collagen-containing bone graft substitute, may expedite bone repair. As such, using a critical size rat calvaria defect, we implanted a collagen scaffold containing bone graft substitute (i.e., Bone graft scaffold, BG) or BG supplemented with costal chondrocytes (cBG). The rats were subjected to live CT imaging at 1, 6, 9, and 12 weeks following the surgical procedure and sacrificed for microCT imaging of the defect site. Moreover, serum markers and histological evaluation were assessed to determine osseous tissue regeneration and turnover. Live CT and microCT indicated cBG implants displayed expedited bone repair vs, BG alone, already at 6 weeks post defect induction. cBG also displayed a shorter distance between the defect edges and greater mineral apposition distance compared to BG. Summerizing, the data support the addition of chondrocytes to bone substitute, accelerates the formation of new bone within a critical size defect.

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.

Maxillofacial Fractures: A Four-Year Retrospective Study of 1828 Cases in West China

OBJECTIVE

To analyze the epidemiological and clinical characteristics of maxillofacial fracture cases in a stomatological center in southwest China.

METHODS

This study includes 1828 cases of maxillofacial fractures treated in our hospital from January 2018 to December 2021. We analyzed the gender, age, causes of injury, fracture sites, concomitant injuries, treatment, and postoperative infection of these cases. Our data are also compared with those from similar domestic studies.

RESULTS

Among the 1828 cases, the male-to-female ratio was 2.48:1 with an average age of 34.55 ± 16.36 years. The highest incidence of fracture was 21-50 years old, and the most common cause of injury was falls (38.95%). There was a statistically significant difference in the composition of injury causes among different age groups(P<0.05). Mandible (37.56%) was the most easily fractured site, and limb injury (17.89%) was the most common concomitant body injury. In all cases, 85.23% of patients were treated with open reduction and internal fixation.  Conclusions: Maxillofacial fractures often occur in the mandible of young and middle-aged men. Falls and traffic accidents are the main causes of injury, often accompanied by limb and brain injuries. Open reduction and internal fixation is still the most commonly used treatment. There are some differences in the results reported by different domestic hospitals.

The Promoting Effect of a Local Pulsatile Parathyroid Hormone Delivery on Healing of the Mandibular Fracture in Rats

Parathyroid hormone (PTH) can promote bone formation and mineralization in mandibular fractures, and is systemically administered through daily injections. In this study, the local delivery of PTH using carboxymethyl chitosan/polyvinyl alcohol and alginate was investigated. Bovine serum albumin was used as a drug substitute, and the delivery system was verified to release drugs in a pulsed rhythm. After the delivery system was subcutaneously implanted in Sprague-Dawley (SD) rats, no rejection reaction was detected, indicating that it has good biocompatibility and biodegradability in vivo. Then, an SD rat model of mandibular fracture was established, and 24 rats were randomly divided into two groups. The control group was reduced and fixed with screws and a microplate, and the experimental group received pulsatile PTH release system (14 μg PTH) + screws and microplate fixation. The animals were euthanized on postoperative weeks 1-4. Observation of gross specimens, digital radiography, and hematoxylin and eosin showed that the local PTH pulsatile release system promoted osteogenesis and accelerated fracture healing. In summary, PTH can be loaded by biomaterials to locally target the fracture and stimulate bone formation. Moreover, the pulsatile PTH release system provides a potential therapeutic protocol for mandibular fracture. Impact statement Our study prepares a drug release system that could impulsively release parathyroid hormone. The system could enhance bone regeneration in rats with mandibular fracture. These data provide a foundation for future studies aimed to understand and optimize the use of bioactive molecule pulsatile delivery for bone regeneration and tissue engineering applications.

Paediatric Mandibular Fracture Management - A Seven Year Retrospective Study

Introduction

Mandibular fractures are one of the most frequent and complex types of traumatic injuries of the maxillofacial region in children. Given significant long-term sequelae of inappropriate healing, adequate diagnosis and choice of management, which takes into account the patient's age and fracture characteristics, are paramount.

Methods

The data for this study were obtained from the medical records of patients treated in the Department of Surgical Dentistry and Paediatric Maxillofacial Surgery of the Bogomolets National Medical University from 2014 to 2020. Age, gender, fracture pattern and surgical treatment methods performed in these patients were recorded and analysed.

Results

A total of 302 children with 376 traumatic fractures of the mandible were managed during the study period. The largest number of fractures was found in the condylar processes region, 42%, and in the body of the mandible, 40%. The majority of patients were males and in the 13-17 age group (147 [49%] cases). Tigerstedt's maxillary-mandibular fixation splint was used in the majority of cases, alone or in the combination with open or internal fixation.

Discussion

Whilst the most common type of immobilisation in children in our series was Tigerstedt's maxillary-mandibular fixation splint, its use is limited to the variable bite period. Alternative fixation options are discussed.

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.

Background

Injury has become a life threatening community health problem associated with significant mortality and morbidity worldwide. The aim of this study was to assess the burden of injury in Dilla University Hospital.

Methods

Institution-based retrospective cross-sectional study was conducted from January 2015 to June 2019. Data was collected using questionnaire adapted from WHO injury surveillance guideline. Bivariate and multivariate logistic regressions were performed to determine the factors associated with hospital mortality.

Results

Road traffic accident was the commonest cause of injury 178(47.3%) followed by interpersonal violence 113(30.1%). Revised trauma score (RTS) < 10 (AOR=2.5; 95% CI, 1.8–25.6), Glasgow coma scale (GCS) (AOR =0.3; 95% CI, 0.13–0.5), length of hospitalization (LOS) 1–7 days (AOR=0.1; 95% CI, 0.01–0.8) and time of arrival >24hr were predictors of mortality in a patient with injury.

Conclusion

Lower extremity injury was common and mostly associated with RTA. Pre-hospital emergency medical service system and trauma registry need to be established to decrease the burden of injury.

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

PURPOSE

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSIONS

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

Craniofacial Injuries Seen Among Electric-Motorized Bicycle Riders

The popularity of electric-motorized bicycles (E-bikes) has increased dramatically over the past few years. As a result, E-bike--associated injuries are quickly becoming a substantial issue. The aim of the present study was to evaluate the epidemiology and general nature of these injuries, with special attention to craniofacial trauma. This was a retrospective study of 84 E-bike riders who suffered from trauma and treated at our level 1 trauma center between the years 2014 and 2018. The information consisted of demographics, characteristics of injury, Injury Severity Score, and number of hospitalization days.Regarding craniofacial trauma, the mean age was 22.7 years. Data about helmet usage was missing. The most common cause of injuries in maxillofacial region, was falling (80%). The most prevalent injury in the maxillofacial region was fractures of the zygomatic complex with the orbit (33%) and soft tissue lacerations.There is little data regarding craniofacial trauma attributed to electric-motorized bicycle accidents. In Israel there are a lot of young adults and teenagers that use E-bikes as an economical solution for mobility. Education regarding road behavior and the proper use of protective measures such as wearing a helmet can reduce significantly overall injuries and cranio-facial trauma in particular.

Influence of SARS-CoV-2 lockdown on the incidence of facial trauma in a tertiary care hospital in Rome, Italy

BACKGROUND

Italy has been the first affected country in the western hemisphere by SARS-CoV-2 with over 200,000 cases during the first months of the pandemics. To control the spread of the virus, the whole country was placed under lockdown with limitations in the circulation of people and vehicles from March 2020 to the first half of the month of May.

METHODS

We aimed to analyze the incidence and type of facial traumas referred to our tertiary care hospital during the months of Italy lockdown due to SARS-CoV-2 spread compared with those during the same months of 2019 to determine eventual variations in the incidence, type and causes of trauma.

RESULTS

During the 2 months of COVID-19-related lockdown, a dramatic decrease in facial trauma patients was observed at our tertiary care hospital with a shift toward older age ranges. Regarding the causes of trauma, the largest percentage reduction was found in road, sports and work accidents; this percentage reduction was not found in aggressions.

CONCLUSIONS

A small increase in the percentage was also found regarding surgical indications, likely because more severe cases were more prone to be referred to the hospital despite the fear of being infected.

Ten-year retrospective study on mandibular fractures in central Taiwan

Objective

To analyse the epidemiology of mandibular fractures and the correlation between combined fractures during a 10-year period in central Taiwan.

Methods

This retrospective study analysed data collected from the medical records of patients that had mandibular fractures between January 2007 and October 2017. Data on age, sex, cause of injury, anatomical site of fracture, treatment and complications were obtained and analysed.

Results

A total of 265 patients who received treatment were included in the study. The mean ± SD age was 30.08 ± 13.47 years (range, 6–70 years) and the 21–30 years age group showed the highest incidence of mandibular fractures. The male-to-female ratio was 1.25:1. Road traffic accidents were the most common cause of fracture (206 of 265; 77.74%). The symphysis and parasymphysis area was the most common fracture site (169 of 420; 39.29%). Single-site fracture represented slightly more than 50% of the total 420 fractures. The most frequent combination of two fractures was an angle fracture combined with a symphysis and parasymphysis fracture (29 of 106 double fracture patients [27.36%]). There was a weak positive association between several combinations of fractures.

Conclusions

A better understanding of the influence of age and sex on the mechanism of injury is of great clinical importance in the assessment and diagnosis of fractures.
