The Incidence and Aetiology of Maxillofacial Trauma and Concomitant Traumatic Brain Injury in a Johannesburg Tertiary Hospital

OBJECTIVE

To investigate the incidence and etiology of maxillofacial trauma (MFT) and its association with traumatic brain injury (TBI).

BACKGROUND

Anecdotal evidence suggests that there is an association between MFT and TBI and that higher incidences of TBI are associated with frontal bone and mid-facial fractures. Despite the large volume of maxillofacial facial fractures treated in the authors' unit, no study has been undertaken to establish the relationship between TBI and maxillofacial fractures.

METHODS

This was a retrospective single-center cross-sectional study that was conducted on patients who presented at Charlotte Maxeke Academic Hospital emergency department with MFT and concomitant TBI over a period of 1 year (January 2019-January 2020). The primary predictor was maxillofacial fractures, which were classified into upper, middle, and lower thirds. The primary outcome variable was TBI indicated by the Glasgow Coma Scale (GCS) and Marshall computed tomography (CT) classification (radiological finding in CT).Variables such as age, etiology, fracture type, and neurological injury indicated by the recorded GCS and Marshall CT classification (I-IV) were collected. Maxillofacial fractures were classified based on the anatomical location. The level of significance was set at P <0.05.

RESULTS

A total of 112 patients (102 males, 10 females) presented with MFT and concomitant TBI. The age group 30 to 39, followed by 20 to 29 years, was most affected. Respectively assault (n = 67), gunshots (n = 16), and falls (n = 16) were the main causes of injury. Supra-orbital rim fractures (P = 0.00193), frontal sinus fractures (P < 0.001,), and panfacial fractures (P < 0.001) were significantly associated with TBI. Severe TBI (GCS: 3-8) was associated with higher Marshall CT grading.

CONCLUSIONS

Facial fractures affecting the upper third and panfacial fractures pose a significant risk for TBI. To identify TBIs, a multidisciplinary evaluation of facial fractures is recommended, especially in high-risk groups.

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

BACKGROUND

Though the epidemiology of craniomaxillofacial (CMF) fractures has been well documented at urban hospitals, the characteristics of these fractures in rural hospitals have not been well studied.

PURPOSE

The purpose of this study is to report on the epidemiology of CMF fractures at a regional Level 1 trauma center serving a large rural population in central Illinois.

STUDY DESIGN, SETTING, SAMPLE

This is a retrospective cohort study at a community-based regional tertiary referral center that serves a predominantly rural population. Inclusion criteria comprised patients with radiologically confirmed CMF fractures between 2015 and 2019. Patients with incomplete medical records were excluded.

PREDICTOR VARIABLE

Predictor variables included demographics (age, admission source, race, and sex) and etiology of CMF fracture (assault/domestic violence, all-terrain vehicle/off-road, falls, farm-related, motor vehicle collisions, gunshot wound, and others).

MAIN OUTCOME VARIABLE

The primary outcome variable was the CMF anatomic location including nasal bone, orbit, mandible, malar/maxillary, and other CMF fractures.

COVARIATES

The covariates are not applicable.

ANALYSES

Descriptive statistics were used to summarize a sample of the population characteristics. Wilcoxon ranked sign tests and χ2 tests of independence were used to assess for statistically significant associations between select variables of interest. Statistical significance was defined as P < .05.

RESULTS

Between 2015 and 2019, a total of 2,334 patients presented to the emergency department with a CMF fracture. After applying the inclusion/exclusion criteria, the final sample was composed of 1,844 patients for the management of 2,405 CMF fractures. The majority of patients were male(62.0%) and young adults (aged 18-39) had the highest number of CMF fractures (819) relative to all other age groups. The most common fracture etiology was fall(37.3%), and nasal bone fractures represented the most common fracture location(41.6%). χ2 analyses revealed statistically significant associations between the anatomic location of CMF fracture incurred, and differing categories of age, admission source, race, sex, and etiology.

CONCLUSION AND RELEVANCE

Our study shows that patients seen at our Midwestern Level 1 trauma center are more likely to present with nasal bone and malar/maxillary fractures due to falls. In studies based in urban centers, patients are likely to present with orbital and mandibular fractures due to falls and assault.

Assault-related Orbital Trauma at an Urban Level I Trauma Center: Racial Segregation and Other Neighborhood-level Social Determinants

PURPOSE

To report the demographics of assault-related orbital fractures over a 7-year period treated at a level I urban trauma center, as well as describe and analyze the variation in assault rates across different racial/ethnic neighborhoods for patients residing in Milwaukee County.

METHODS

A retrospective chart review was conducted for patients who sustained assault-related orbital fractures from January 1, 2013, through December 31, 2019, at the Froedtert & Medical College of Wisconsin, in Milwaukee, Wisconsin. A series of negative binomial regression models evaluating the association of neighborhood (i.e., US census tract) racial/ethnic composition, poverty, unemployment, percentage female head-of-household, and education level with neighborhood rate of orbital trauma was conducted.

RESULTS

A total of 410 adult patients with orbital fractures attributed to assault were identified during the seven-year period, of whom 326 (80%) resided in Milwaukee County. Among these patients, 242 (74%) were male, 260 (81%) were single, and 206 (63%) were non-Hispanic Black. Majority non-Hispanic Black, Hispanic, and Other-type minority neighborhoods have 5.30, 3.35, and 3.94 times higher incidence rates of orbital assault, respectively, compared with the majority of non-Hispanic White neighborhoods. The elevated incidence rates were significantly attenuated across all minority neighborhoods after accounting for neighborhood factors of poverty, unemployment, and low education level. Low education had the strongest association with the incidence of assault-related orbital fractures, followed by unemployment.

CONCLUSIONS

Results indicate that minority neighborhoods suffer from compounded burdens of both social and economic disadvantage as well as violent assaults. Additional resources allocated to poor minority communities are needed.

Quantitative analysis of diplopia following orbital fracture repair

Orbital fractures can result in devastating functional complications to sight and well-being, yet our understanding of functional sequelae post reconstruction is not well understood in the literature. This research retrospectively analysed the activity of a specialist orbital surgeon over five years to evaluate the incidence of, and risk factors for, debilitating complications such as diplopia and restriction of extraocular movement. Orbital fracture cases repaired between 1 January 2015 and 31 December 2019 were retrospectively analysed. Demographics, orthoptic assessment, injury classification, timing, operative details, outcomes, and complications were recorded. Preoperative and postoperative binocular single vision scores (BSV) were recorded to calculate the effect of orbital repair on residual diplopia. Of 582 patients undergoing orbital access, 472 cases of orbital wall reconstruction satisfied the inclusion criteria, of which 162 (34%) were Jaquiéry 4 or 5. Overall, 10.6% had complications, 4.9% had diplopia, and 5.7% were returned to theatre. All those with residual diplopia had had it preoperatively, and had evidence of an improvement in BSV score. Time to surgery, material, and pure orbital fractures had a significant impact on the incidence of diplopia. Defect size did not. Whilst complication rates were low we conclude that strict adherence to a defined surgical protocol, postoperative imaging, and objective assessment of postoperative function are central to maintaining these standards. Objective orthoptic analysis of patients before and after orbital repair is critical to our understanding of this pathology. Whilst preoperative prediction of the persistence of long-term diplopia currently eludes us, further research should target it.

Etiology, Epidemiology, and Treatment Type of Maxillofacial Traumas in Razavi Khorasan Province with Certain Insurance between 2016 and 2021

Background

Trauma is a leading cause of death and disability in developing countries, with maxillofacial fractures being a significant part of such cases. This study focuses on maxillofacial traumas among insured patients in Razavi Khorasan province (2016-2021), exploring the impact of gender, age, and trauma causes on injury prevalence and treatment approaches.

Methods

This retrospective cross-sectional study utilized the records of the patients who were treated for maxillofacial fractures in Mashhad Shahid Kamyab Hospital or a Private Trauma Center, from 2016 to 2021. Demographic characteristics of the patients (age and gender), educational backgrounds of surgeons, accident causes, year and location of the fractures, and reasons for referrals were recorded. The data were statistically analyzed using SPSS 20, and the significance level was set at 0.05.

Results

We examined the records of 60 patients (44 males, 16 females). Males (73.4%) exhibited a significantly higher prevalence of maxillofacial traumas compared to females (26%) (P Value < 0.05). Falling was identified as the most common cause of fractures (51.7%), followed by impacts from hard objects and motor vehicle accidents (MVA) (P Value = 0.63). Mandible fractures were observed in 48% of patients, followed by zygomaticomaxillary and panfacial fractures, subsequently (P Value < 0.05).

Conclusion

The study findings highlight the impact of age, gender, and trauma causes on maxillofacial fractures and treatments among patients with certain insurance. Understanding the origins and patterns of these fractures offers crucial insights for shaping effective health policies, providing valuable guidance for addressing such injuries in this population.

Etiology and pattern of maxillofacial trauma

Introduction

Maxillofacial trauma can be limited to superficial lacerations, abrasions, and facial bone fractures. The objective of this study was to determine the etiology, pattern, and predictors of soft tissue and bony injuries.

Materials and methods

This study was conducted in the department of maxillofacial surgery Lady Reading hospital Pakistan from Jan 2019 to June 2021. The nonprobability consecutive sampling technique was used for the selection of patients. All patients were assessed clinically and radiologically. The neurosensory examination was done for any altered sensation, anesthesia, or paresthesia. Motor nerve function was also assessed clinically. Data were analyzed using SPSS version 26. The etiology and pattern of maxillofacial trauma were stratified among age and genders using the chi-square test to see effect modifiers. Tests for regression analysis were also applied. P≤0.05 was considered significant.

Results

A total of 253 patients meeting inclusion criteria were included in this study. The majority of these patients were males, 223 (88.1%), while only 30 (11.9%) were females. The mean age for the group was 25.4 ± 12.6 years. RTAs were the most common causes of trauma (63.6%) followed by assault (15.0%), falls (11.5%), FAIs (5.9%), and sports (0.4%). The most vulnerable skeletal part was the mandible (22.9%) followed by Zygoma (7.1%), significantly predicted by RTAs. Soft tissue laceration analysis showed a high frequency of multiple lacerations (38%) significantly predicted by FAIs. The frequency of trigeminal nerve injury was 5.5% (14 patients) and that of the facial nerve was 1.6% (4 patients). The strongest association of nerve injury was with firearm injury (47%), followed by road traffic accidents and sports injuries.

Conclusion

Road traffic accident was the most common etiological factor and mandible fracture was commonly predicted by RTA. Trigeminal nerve injuries were common, frequency of nerve injuries was highly associated with mandible fracture and was predicted by FAI.

An evidence-based approach to antibiotic use in maxillofacial trauma

A patient with craniomaxillofacial (CMF) trauma often receives consultations from multiple medical and surgical services. Antibiotics are sometimes prescribed without consistent evidence. This article reviews current literature regarding antibiotic prophylaxis of patients with CMF fractures. This article also presents the guidelines for the appropriate use of antibiotics for patients with CMF fractures at 2 level I trauma centers.

What Are the Risk Factors of Incurring Maxillofacial Fractures From Unarmed Hand-To-Hand Combat?

PURPOSE

The purpose of our study was to determine the risk factors of incurring maxillofacial fractures among individuals who engage in unarmed hand-to-hand combat.

METHODS

The following retrospective cohort study was competed using data from the Nationwide Inpatient Sample. The primary predictor variable was blood alcohol level. The primary outcome variable maxillofacial fracture. We used SPSS to conduct all statistical analyses.

RESULTS

Our final sample consisted of 9,441 patients injured from unarmed hand-to-hand combat. The mean age of the sample was 38.7 years. The most common age group was young adults (42.9%), followed closely by middle-aged adults (41.9%). The number of males was nearly 4 times that of females. The mandible was the most frequently fractured maxillofacial bone. Concerning the mandible per se, the angle (37.1%) was the most frequently fractured site, while the coronoid process (0.2%) was the least frequently fractured site. Relative to females, males were 2.7 times more likely to incur a craniomaxillofacial fracture (P < .5).

CONCLUSIONS

Males had an increased risk of maxillofacial fracture relative to females. The mandible, particularly the angle, was the most frequently fractured maxillofacial bone. We speculate this is because hooks are frequently thrown in unarmed hand-to-hand combat.
