Characterization of Age-Related Injury Patterns and Surgical Treatment of Pediatric Facial Fractures: Analysis of the National Trauma Data Bank

Characteristics, Treatment, and Prognosis of Pediatric Symphyseal/Parasymphyseal-Condylar Fractures

BACKGROUND

Pediatric condylar fractures combined with symphyseal or parasymphyseal fractures are common but challenging to manage. The authors present fracture characteristics, propose a treatment algorithm, and evaluate the treatment prognosis of pediatric symphyseal/parasymphyseal-condylar fractures.

METHODS

A retrospective review was conducted on pediatric patients who underwent treatment for symphyseal/parasymphyseal-condylar fractures in a trauma center between January of 2006 and January of 2021. Demographic and fracture characteristics were recorded. Complications and functional evaluations, including maximum interincisal opening, Helkimo anamnestic index, and clinical dysfunction index, were assessed after at least 1 year of follow-up.

RESULTS

After screening, 104 participants met the inclusion criteria. Among them, 50.96% received open reduction and internal fixation for symphyseal/parasymphyseal fractures and closed treatment for condylar fractures, 45.19% were treated by liquid diet and functional exercise, and the remaining 3.85% with severe malocclusion were treated with the assistance of orthodontic appliances. During follow-up, the average maximum interincisal opening of the patients increased from 17 ± 6.29 mm to 41.64 ± 6.33 mm. No subjective symptoms were observed in 86.54% of the patients and 79.81% showed no or mild clinical symptoms. Except for 1 patient who developed temporomandibular joint ankylosis, no other severe complication was reported. Postfracture remodeling of the nonfractured condyle was noted in 3 cases.

CONCLUSIONS

Pediatric symphyseal/parasymphyseal-condylar fractures present unique biomechanical and anatomic challenges that require special consideration during management. In this study, satisfactory functional prognosis was achieved following implementation of the treatment algorithm.

Pediatric Craniomaxillofacial Fractures: A Review

Pediatric facial fractures constitute a small portion of all facial fractures. The frequency of pediatric facial fractures by location, and mechanism of injury, changes over time associated with craniofacial growth and activity. Pediatric patients have protective anatomic features, such as increased soft tissue, excess adipose tissue, and more flexible bone. Conservative management is often sufficient. Surgical intervention can often be conservative. Follow-up monitoring is valuable for concerns of growth disruption from either the trauma itself or surgical interventions. Older teenage patients may often be treated similar to adults. Postoperative management varies by fracture type without a defined long-term follow-up course.

Accidental and Abusive Mandible Fractures in Infants and Toddlers

OBJECTIVE

Mandible fractures are uncommon injuries in infants and young children and may raise concern for nonaccidental trauma. Our study describes several children with mandible fractures to identify features that might differentiate abuse from accident.

METHODS

Records and imaging were reviewed for children aged 24 months and younger who were diagnosed with mandible fractures at 2 tertiary pediatric care centers. Twenty-one cases were included, 8 of whom had formal child abuse consultations. Cases were reviewed for mechanisms of injury, physical examination findings, and occult injuries identified, as well as the final abuse determination.

RESULTS

Among children with child abuse consultations, 5 injuries (62.5%) were determined to be accidental, 1 (12.5%) was abusive, and 2 were indeterminate for abuse or accident (25%). In each accidentally injured child, the reported mechanism of injury was a short fall with evidence of facial impact. No accidentally injured child had unexpected occult injuries or noncraniofacial cutaneous injuries.

CONCLUSIONS

Infants and young children can sometimes sustain mandible fractures accidentally after well-described short falls with evidence of facial impact. Abuse remains in the differential diagnosis, and children should be evaluated accordingly. We propose that accidental injury be considered when a well-evaluated child with an isolated mandible fracture has a history of a short fall.

Trends in mandibular fractures in the USA: A 20-year retrospective analysis

BACKGROUND/AIM

The mandible is one of the most fractured bones in the maxillofacial region. This study analyzes trends in mandibular fracture patterns, demographics, and mechanisms since the early 2000s.

MATERIAL AND METHODS

Mandibular fractures were reviewed from the 2007, 2011, and 2017 National Trauma Data Bank including 13,142, 17,057, and 20,391 patients by year, respectively. This database contains hundreds of thousands of patients annually and represents the largest trauma registry in the United States. Variables included number of fractures, sex, age, injury mechanism, and fracture location. Mechanism of injury included assault, motor vehicle crash, fall, motorcycle, bicycle, pedestrian, and firearm. Anatomic locations based on ICD-9/10 codes included symphysis, ramus, condyle, condylar process, body, angle, and coronoid process. Frequencies were compared using Chi-square tests of homogeneity with effect sizes estimated using Cramer's V.

RESULTS

Mandibular fractures represent 2%-2.5% of all traumas reported in the database from 2001 to 2017. The proportion of patients sustaining a single reported mandibular fracture decreased from 82% in 2007 to 63% in 2017. Males consistently experienced 78%-80% of fractures. Eighteen to 54-year-olds experienced the largest percentages of fractures throughout the 21st century, while median age of fracture shifted from 28 to 32 between 2007 and 2017. The most common fracture mechanisms were assault (42% [2001-2005]-37% [2017]), motor vehicle crash (31%-22%) followed by falls (15%-20%). From 2001-2005 to 2017, a decrease was observed in assaults (-5%) and motor vehicle crash (-9%) and an increase in falls (+5%), particularly among elderly females. The mandibular body, condyle, angle, and symphysis represent approximately two-thirds of all fractures without a consistent temporal trend among them.

CONCLUSIONS

The temporal trends observed can be linked to shifting age demographics nationally that may aid clinicians in diagnosis and inform public safety policies aimed at reducing these injuries, particularly among the growing elderly population.

Concomitant Cervical Spine Injuries in Pediatric Maxillofacial Trauma: An 11 Year Review of the National Trauma Data Bank

PURPOSE

Craniofacial trauma with concomitant cervical fractures (CCFs) is responsible for significant morbidity and mortality in the pediatric population. We aim to characterize its incidence, injury patterns, outcomes, and risk factors, along with identifying any association between mandible fractures and cervical injuries via the National Trauma Databank.

METHODS

A retrospective cohort study was performed using National Trauma Databank records between 2007 and 2017 to identify patients equal or under the age of 18 years hospitalized for maxillofacial trauma and with recorded cervical injury. Variables of interest include age, gender, race/ethnicity, trauma type (blunt vs penetrating), Injury Severity Score, area involved, mechanism of injury, comorbid conditions, inpatient complications, and discharge disposition. Retrospective cohorts were separated by CCF status. Univariate, bivariate, and multivariable regression analysis was utilized, with P-value <.05 considered statistically significant.

RESULTS

A total of 32,952 patients were included in the study, with the majority being White (60.8%), male (68.2%), and between the ages of 13 and 18 years (65%). Of these, 8.2% experienced CCF. Most common mechanisms of injury were motor vehicle trauma (32.6%), interpersonal violence (18.8%), and falls (13.5%). Univariate analysis revealed patients with CCF were significantly older (15.2 vs 12.9; P < .001), more likely to be motor vehicle occupants (46.6 vs 31.9%; P < .001), and suffer polyfacial fractures (62.6 vs 60.7%; P < .001). Longer length of stay (9.4 vs 3.6 days; P < .001) and significantly higher inpatient complications such as deep vein thrombosis, pulmonary embolism, unplanned intubation, severe sepsis, pressure ulcer, ventilator-associated pneumonia, and unplanned return to operating room were observed in the CCF cohort. Female gender (1.5 [1.37 to 1.64; 95% confidence interval {CI}] P < .001) and higher Injury Severity Score (1.12 [1.11 to 1.11; 95% CI] P < .001) were associated with significantly higher odds on multivariable analysis. The presence of a mandible fracture was not associated with increased CCF on multivariate analysis (1.06 [0.92 to 1.22; 95% CI] P = .36).

CONCLUSIONS

There are statistically significant differences in demographics, outcomes, and injury patterns in maxillofacial patients with CCF that may help guide treatment. No association between mandible fractures and cervical trauma was identified.

The use of machine learning for investigating the role of plastic surgeons in anatomical injuries: A retrospective observational study

While plastic surgeons have been historically indispensable in the reconstruction of posttraumatic defects, their role in trauma centers worldwide has not been clearly defined. Therefore, we aimed to investigate the contribution of plastic surgeons in trauma care using machine learning from an anatomic injury viewpoint. We conducted a retrospective study reviewing the data for all trauma patients of our hospital from March 2019 to February 2021. In total, 4809 patients were classified in duplicate according to the 17 trauma-related departments while conducting the initial treatment. We evaluated several covariates, including age, sex, cause of trauma, treatment outcomes, surgical data, and severity indices, such as the Injury Severity Score and Abbreviated Injury Scale (AIS). A random forest algorithm was used to rank the relevance of 17 trauma-related departments in each category for the AIS and outcomes. Additionally, t test and chi-square test were performed to compare two groups, which were based on whether the patients had received initial treatment in the trauma bay from the plastic surgery department (PS group) or not (non-PS group), in each AIS category. The department of PS was ranked first in the face and external categories after analyzing the relevance of the 17 trauma-related departments in six categories of AIS, through the random forest algorithm. Of the 1108 patients in the face category of AIS, the PS group was not correlated with all outcomes, except for the rate of discharge to home (P < .0001). Upon re-verifying the results using random forest, we found that PS did not affect the outcomes. In the external category in AIS, there were 30 patients in the PS group and 56 patients in the non-PS group, and there was no statistically significant difference between the two groups when comparing the outcomes. PS has contributed considerably to the face and external regions among the six AIS categories; however, there was no correlation between plastic surgical treatment and the outcome of trauma patients. We investigated the plastic surgeons' role based on anatomical injury, using machine learning for the first time in the field of trauma care.

A quantitative analysis of trauma patients having undergone plastic surgery

Purpose

While plastic surgeons have been historically indispensable in reconstruction of posttraumatic defects, their role in Level I trauma centers around the world has not yet been clearly approved. This study aims to assess the contribution of plastic surgeons in major trauma care by evaluating the characteristics of trauma patients underwent plastic surgery at a Level I trauma center.

Method

From November 2014 to October 2020, we conducted a retrospective review of our hospital’s Trauma Registry System for patients with an Injury Severity Score (ISS) of 9 or higher. Of all of 7174 patients, the plastic surgery (PS) department treated 870 patients; the 6304 patients not treated by the PS were classified as the Non-PS. Then, we performed propensity score matching to reduce the statistical bias, after the death in the emergency room and the missing value were considered exclusion criteria.

Result

The mean ISS showed no significant difference between two groups (16.29 ± 7.04 in the PS vs. 16.68 ± 9.16 in the Non-PS, p = 0.3221). According to investigate the Abbreviated Injury Scale, both head and neck (65.0%) and face (46.4%) categories showed significantly higher in the PS group than the Non-PS group (p < 0.0001), and its contribution ratio was 2.151 and 21.822 times, respectively.

Conclusion

This study revealed the specialty of plastic surgery was face area in trauma care. We thus argue that plastic surgical care is imperative for trauma patients, and expect to be implicated in trauma system planning.

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

BACKGROUND/AIMS

No studies have characterized the morbidity and mortality of maxillary & malar fractures on a national scale. The aim of this study was to examine the risk factors for mortality in pediatric patients who had sustained maxillary and malar fractures by using a national pediatric hospital inpatient care database.

MATERIALS AND METHODS

This retrospective cohort study was conducted using the Kids' Inpatient Database (KID). The primary predictor variable was the cause of injury. The primary outcome variable was mortality rate. Additional predictor variables included age, gender, race, income, payer information, year and place of injury, number of facial fractures, concomitant facial fractures, other fractures of the body, and intracranial/internal organ injury. Univariate and multivariate regression models were performed to assess risk factors for mortality. Statistical significance was set to a p-value <.05.

RESULTS

A total of 5859 patients met the inclusion criteria. The most common age group was 13-17 years of age (n = 3816, 65.1%). Motor vehicle accidents were the most common mechanism of injury (n = 2172, 37.1%). The presence of cranial vault (OR = 2.81, p = .017), skull base (OR = 2.72, p < .001), and vertebral column fractures (OR = 2.13, p = .016), as well as sub-arachnoid hemorrhage (OR = 4.75, p = .005), traumatic pneumothorax/hemothorax (OR = 2.16, p = .015), and heart/lung injury (OR = 3.37, p < .001) were each independently associated with increased odds of mortality.

CONCLUSIONS

Patients in their late teens most commonly sustained malar and maxillary fractures, likely due to general trends in craniomaxillofacial development. The presence of other fractures located in close proximity to the mid-face increased the risk of mortality among pediatric patients with malar and maxillary fractures. This may be explained by the anatomical approximation of the mid-face to vital neurovascular structures of the head, which, when damaged, may prove fatal.

Zygoma Fractures Are Associated With Increased Morbidity and Mortality in the Pediatric Population

BACKGROUND

Trauma involving the facial bones has been shown to be associated with high severity in previous studies. Characteristics of facial fractures in adults have been well described in the adult population, less so in the pediatric literature. Our investigation aims to define these epidemiological measures and risk factors for poor outcomes using the most recent data.

METHODS

The 2016 Trauma Quality Improvement Program data bank was examined to study facial fracture pattern, mechanism of injury, and demographic descriptive data to characterize pediatric trauma patients. Multivariable regression analysis was performed to assess risk factors for morbidity and mortality in pediatric facial fracture patients.

RESULTS

Of 51,168 total pediatric trauma patients, 2917 (5.7%) presented with facial fractures. Motor vehicle trauma was the most common mechanism of injury. Maxillary/malar fractures was the most common fracture type overall. Mandibular fractures were most common in the 0 to 1 age category while nasal bone fractures were more common in older patients. Patients with mandible fractures experienced the highest rate of operative management. Zygoma fracture was highly associated with concomitant traumatic brain injury. Multivariable regression analysis showed that fracture of the zygoma, concomitant traumatic brain injury, and cervical spine injury were risk factors for increased mortality.

CONCLUSION

Facial fractures are a rare but significant form of trauma in the pediatric population. Our data suggests a slight change in fracture patterns compared to previous studies. Zygoma fractures, traumatic brain injury, and cervical spine injury are risk factors of increased mortality that clinicians should be aware of.

Combined Symphyseal and Condylar Fractures: Considerations for Treatment in Growing Pediatric Patients

BACKGROUND

Combined symphyseal-condylar mandible fractures are relatively common but difficult to manage in children. This study investigated the cause and management of symphyseal-condylar fractures in pediatric patients.

METHODS

This study presents a retrospective review and expert opinion of pediatric symphyseal-condylar mandibular fracture management at the authors' institution between 1990 and 2019. National data from the Healthcare Cost and Utilization Project Kids' Inpatient Database (2000 to 2016) were used to determine whether institutional data had national applicability.

RESULTS

Twenty-one patients at the authors' institution met inclusion criteria. Of these patients, 26.7 percent of deciduous dentition patients underwent open reduction and internal fixation, 40 percent underwent closed treatment (maxillomandibular fixation), and 33.3 percent received a soft diet. All mixed dentition patients underwent open reduction and internal fixation or closed treatment; all permanent dentition patients underwent open reduction and internal fixation. The national database (n = 1708) demonstrated similar treatment patterns: most permanent dentition patients (88.7 percent) underwent open reduction and internal fixation, most mixed dentition patients (79.2 percent) underwent closed treatment, and among deciduous dentition patients, 53.5 percent patients received a soft diet; 38 percent received closed treatment. In this study, the overall posttreatment complication rate was 62.5 percent among open reduction and internal fixation patients, 14.3 percent among closed treatment patients, and 16.7 percent among patients treated with a soft diet.

CONCLUSIONS

Symphyseal-condylar mandibular fractures were associated with substantial morbidity in children. The authors created a treatment algorithm to maximize outcomes in children who suffer from this challenging fracture pattern.

Injury Patterns in Pediatric Facial Fractures Unique to an Urban Environment

This study aimed to define better the clinical presentation, fracture patterns, and features predictive of associated injuries and need for surgery in pediatric facial trauma patients in an urban setting. Charts of patients 18 years or younger with International Classification of Disease 9th and 10th revision (ICD-9/ICD-10) codes specific for facial fractures (excluding isolated nasal fractures) at NY-Presbyterian/Weill Cornell Medical Center between 2008 and 2017 were retrospectively reviewed. Of 204 patients, most were referred to the emergency department by a physician's office or self-presented. Children (age 0-6 years) were most likely to have been injured by falls, while more patients 7 to 12 years and 13 to 18 years were injured during sporting activities (p < 0.0001). Roughly half (50.5%) of the patients had a single fracture, and the likelihood of surgery increased with greater numbers of fractures. Older patients with either orbital or mandibular fractures were more likely to undergo surgery than younger ones (p = 0.0048 and p = 0.0053, respectively). Cranial bone fractures, CSF leaks, and intracranial injuries were more common in younger patients (p < 0.0001) than older patients and were more likely after high energy injuries; however, 16.2% of patients sustaining low energy injuries also sustained cranial bone, CSF leak, or intracranial injury. In an urban environment, significant pediatric facial fractures and associated injuries may occur after nonclassic low kinetic energy traumatic events. The age of the patient impacts both the injuries sustained and the treatment rendered. It is essential to maintain a high index of suspicion for associated injuries in all pediatric facial trauma patients.

Comparison of outcome of open reduction and internal fixation versus closed treatment in pediatric mandible fractures-a retrospective study

The aim of the study was to compare the outcome and complications of open reduction and internal fixation (ORIF) with closed treatment, as well as to review the literature. This was a retrospective study on pediatric patients with mandible fracture. The primary objective was a comparison of outcomes in terms of bone healing, maximal incisal opening (MIO), and occlusion, and the secondary objective was to review complications. A total of 77 pediatric patients (age <12 years) were managed with closed treatment and 23 with ORIF. In all, 62 patients were found with a single fracture (22 patients with parasymphysis fracture and 21 with condyle fracture, followed by symphysis, angle, and body fracture) and 38 patients with more than one fracture, with symphysis and bilateral condyle fracture being the most common. Bone healing was observed in all the patients. Mean MIO was 26.9 ± 2.8 mm and 29.3 ± 1.7 mm in the closed and ORIF group, respectively, and the difference was statistically nonsignificant (p = 0.5). One patient (1.3%) had deranged occlusion, and mobility was observed in one patient (1.3%) in the closed treatment group. Infection and nerve paresthesia were not seen in any patient at follow-up. Although closed treatment is preferred, as it preserves the soft tissue and periosteum, a displaced mandible fracture especially with co-existing condylar fracture should be treated by ORIF.

What Factors Are Associated With Open Treatment of Pediatric Mandibular Fractures?

PURPOSE

There is a paucity of data with respect to management of pediatric facial fractures. The purpose of this study was to describe the population of pediatric patients with mandibular fractures at our institution and to assess predictors of fractures requiring open reduction and internal fixation (ORIF).

PATIENTS AND METHODS

This was a retrospective cohort study of patients aged ≤17 years presenting with mandibular fractures. The primary predictor variable was age ≥13 years and <13 years. The primary outcome variable was ORIF (yes or no). Epidemiologic factors and complications were also assessed. Descriptive, bivariate, and multiple logistic regression statistics were computed to measure the association between predictor variables and ORIF.

RESULTS

The study sample was composed of 84 subjects with 61 subjects aged ≥13 years and 23 subjects aged <13 years. ORIF was used for 21.4% of subjects. Increased age was associated with ORIF (P = .009). After adjusting for the effects of concurrent variables, age (P = .047, OR = 2.30, 95% CI = 1.01 to 5.24), fracture displacement between 2 and 4 mm (P = .032, OR = 18.1, 95% CI = 1.29 to 254), fracture displacement >4 mm (P = .019, OR = 16.9, 95% CI = 1.60 to 179), and the presence of 3 fractures (P = .027, OR = 30.8, 95% CI = 0.001 to 0.641) were positive independent predictors of ORIF. Concomitant facial, skull, or skull base fractures (P = .039, OR = 0.027, 95% CI = 0.001 to 0.641) were a negative independent predictor of ORIF. Secondarily, both mechanism of injury and fracture location varied significantly by age and gender. Complication rate was 6.33%.

CONCLUSIONS

Most pediatric mandibular fractures were managed nonoperatively. Increased age, fracture displacement, presence of 3 fractures, and concomitant craniofacial injuries were independent predictors of ORIF. Complication rates were low regardless of treatment modality.

Injury Patterns and Demographics in Child and Adolescent Assault Victims Presenting to US Emergency Departments

Objective

To correlate injury patterns with patient demographics in child and adolescent assault victims.

Methods

The National Electronic Injury Surveillance System-All Injury Program data for the years 2005 through 2015 was used. Injuries due to assault were identified and analyzed with SUDAAN 11.0.01™ software to account for the weighted, stratified nature of the data.

Results

There were an estimated 4,407,009 ED visits for assault in patients ≤ 19 years of age. With increasing age, the percentage of females decreased. Sexual assaults were more common in females (87.4%), and robbery/burglary was more common in males (79.8%). When the perpetrator was a spouse/partner, the assault victim was most commonly female (88.8%), and when a stranger, the assault victim was most commonly male (71.5%). With increasing age, the percentage of sexual assaults decreased while the reason for the assault being unknown increased. The assault occurred in the home in 59.6% of those ≤ 4 years of age, decreasing to 18.7% in those 15 to 19 years of age. The anatomic location was the head/neck in 32.8% of those ≤ 4 years of age, increasing to 60.6% in those 15-19 years old. Those ≤ 4 years old had the highest hospital admission rate (8.3%). The main diagnoses were concussion (3.0%), contusion/abrasion (33.3%), fracture (11.5%), laceration (11.5%), internal organ injury (11.5%), puncture (2.8%), and strain/sprain (20.7%). The number of assaults from 2005 to 2015 decreased for all age groups except for those ≤ 4 years old.

Conclusions

These data provide a comprehensive overview of child and adolescent assault victims presenting to the ED in the USA and can be used as background data for further study. The decreasing numbers of assaults over the 11 years of the study are encouraging, and challenges still exist in decreasing the number for those ≤ 4 years old.

Paediatric mandibular fracture-a diagnostic challenge?

The purpose of this study was to clarify the frequency of missed mandibular fractures and to identify possible predictive factors for missed diagnosis. This was a retrospective study that included patients <20 years of age with a recent mandibular fracture. The outcome variable was missed mandibular fracture, which was determined when a fracture was not suspected or diagnosed during the patient's first assessment in primary healthcare. The primary predictor variable was age group (i.e. children <13 years or teenagers/adolescents aged 13-19 years). The explanatory variables were sex, mechanism of injury, and type of facial facture. Other variables were clinical symptoms and findings. Mandibular fracture was missed at first contact in 27 of 182 patients (14.8%). Fracture was missed significantly more often in patients <13 years than in older patients (33.3% vs. 8.8%, P<0.001). The only significant symptom or clinical finding that was associated with missed fractures was skin wound of the jaw (P=0.009). There was no association between missed fracture and sex or mechanism of injury. Mandibular fractures in children are often missed at the first healthcare contact. Careful examination is necessary in paediatric mandibular injuries, particularly in the youngest age groups. Consultation should be smooth between paediatric trauma units and maxillofacial surgeons.

Differences in Facial Fracture Patterns in Pediatric Nonaccidental Trauma

BACKGROUND

The purpose of this study was to characterize differences in facial fracture injury patterns among pediatric patients at highest risk of abusive head trauma/nonaccidental trauma (age ≤ 5 years).

METHODS

Using the National Trauma Databank from 2007 to 2015, patients (age ≤ 5 years) suffering facial fractures were included. Demographics and injury characteristics were compared between those sustaining accidental versus nonaccidental trauma (NAT).

RESULTS

Over 9 years 9741 patients were included with 193 patients (2.0%) suffering NAT. Nonaccidental trauma patients were younger (median [interquartile range]; 0 [0, 2] versus 3 [1, 4], P < 0.001), and more frequently were insured by Medicaid (76.7% versus 41.9%, P < 0.001). NAT patients were more likely to sustain mandible fractures (38.9% versus 21.1%, P < 0.001), but less likely to sustain maxilla (9.8% versus 18.3%, P = 0.003), or orbital fractures (31.1% versus 53.4%, P < 0.001). Nonaccidental trauma patients had fewer instances of multiple facial fracture sites (8.9% versus 22.6%, P < 0.001). Among those sustaining mandible fractures, NAT patients were more likely to sustain condylar fractures (75.8% versus 48.4%, P < 0.001), but less likely to sustain subcondylar fractures (0% versus 13.2%, P = 0.002), or angle fractures (1.6 versus 8.7%, P = 0.048).

CONCLUSIONS

Differences exist in facial fracture patterns in accidental versus nonaccidental trauma within the pediatric population at highest risk for abusive head trauma. Specifically, NAT is associated with fractures of the mandibular condyle and involve fewer facial fracture sites. In the appropriate context, presence of these fractures/patterns should increase suspicion for NAT.
