Assault-related facial fractures: does the injury mechanism matter?

Open Mandible and Maxillary Fractures Associated with Higher Risk of Infection in Victims of Assault

Background: Victims of assault (VOA) often present with fractures of the mandible and maxilla. They represent a complex challenge because of possible compromise of the airway, and infection-related complications because of potential involvement of the oral cavity. We hypothesized that open mandible and maxillary fractures in VOA are associated with a higher rate of infection compared with non-VOA patients with open facial fractures. Patients and Methods: Patients admitted to our level 1 trauma center from 2005 to 2020 with a diagnosis of open mandible and maxillary fractures were included. Demographics, mechanisms of injury, fracture location, cultures, infectious complications, antibiotic treatments, and clinical outcomes were abstracted. Patients were stratified by their mechanism of injury into VOA or non-VOA and were compared using χ2 and Student t-test using SPSS (IBM Corp, Armonk, NY). Results: We identified 316 patients with open mandible and maxillary fractures. There were 198 patients categorized as being VOA, and 118 as non-VOA. Nineteen of 316 patients were diagnosed with infection related to the fracture (3.8% abscesses, 1.9% cellulitis, and 1.9% osteomyelitis). Although the Injury Severity Score (ISS) was higher in non-VOA patients (5.8 ± 2.6 vs. 4.9 ± 1.8; p < 0.013), most of the infections were in the VOA cohort (17/19; 89.5%; p < 0.013). Conclusions: Open fractures of the mandible and maxilla in VOA are associated with a greater risk of infection compared with non-victims of assault. The relation between VOA and poor SDH has been studied recently; clinicians should be aware of this association and implement special considerations and appropriate follow-up visits to decrease the rate of infection in this currently expanding population.

The Causes and Prevalence of Maxillofacial Fractures in Iran: A Systematic Review

Background

Maxillofacial fractures are a common type of injury that can result in significant morbidity and mortality. We aimed to systematically review the literature on the prevalence and causes of maxillofacial fractures in Iran to estimate the overall prevalence of maxillofacial fractures and the most common causes.

Methods

A systematic search of PubMed, Cochrane Library, Web of Science (WS) and Google Scholar (GS) electronic databases was conducted to identify relevant articles published up to January 2023. Studies reporting the prevalence and causes of maxillofacial fractures in Iran were included in the analysis. MOOSE guidelines were adopted for the current systematic review. No data or language restriction were applied. Risk of bias across the articles was assessed.

Results

A total of 32 studies comprising 35,720 patients were included in the analysis. The most common cause of maxillofacial fractures was road traffic accidents (RTAs), accounting for 68.97% of all cases, followed by falls (12.62%) and interpersonal violence (9.03%). The prevalence of maxillofacial fractures was higher in males (81.04%) and in the age group of 21-30 years (43.23%). Risk of bias across studies was considered low.

Conclusion

Maxillofacial fractures are a significant public health problem in Iran, with a high prevalence and RTAs being the leading cause. These results highlight the need for increased efforts to prevent maxillofacial fractures in Iran, especially through measures to reduce the incidence of RTAs.

Violence against women in Israel: injury mechanisms and clinical outcomes following hospitalization

PURPOSE

The objective of this study was to evaluate the relative contributions of different mechanisms of assault to injury and mortality in women in Israel.

METHODS

We identified females hospitalized between 2011 and 2020 following an assault, secondary to blunt, stabbing, or shooting mechanisms of injury, in the Israeli Program for Registration of Trauma Patients (National Trauma Registry). To avoid bias due to temporary hospitalizations for non-medical reasons, we included patients with injuries graded as Abbreviated Injury Scale ≥ 2.

RESULTS

Females accounted for 8.1% (926/11,486) of assault patients in the study population. Compared to males, females were older (40.7 vs. 31.0 years; p < 0.001), more commonly injured by the blunt trauma mechanism (72.1 vs. 48.6%; p < 0.001), and more commonly injured at a place of residence (50.9 vs. 8.2%; p < 0.001). There were no differences in the number of body areas injured, severe Injury Severity Score, and median hospitalization. Males were operated more commonly (44.6 vs. 40.0%; p = 0.008). Mortality in females and males was similar (2.8 vs. 2.3%; p = 0.43). Secondary analysis revealed that blunt injuries were responsible for 61.2% of the severe cases (ISS ≥ 16), 61.4% of the operations, 54.9% of the Intensive Care Unit (ICU) admissions, and 53.8% of the mortality observed in females. When compared to males injured by blunt trauma, females injured by this mechanism were older (43.0 ± 24.7 vs. 32.8 ± 16.1 years; p < 0.001) and had higher mortality (2.1 vs. 0.9%; p = 0.007).

CONCLUSIONS

Assault by mechanisms other than stabbing and shooting should be recognized as a source of severe morbidity and mortality in females.

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.
