Issues in Pediatric Craniofacial Trauma

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.

Expert consensus on pediatric orthodontic therapies of malocclusions in children

Malocclusion, identified by the World Health Organization (WHO) as one of three major oral diseases, profoundly impacts the dental-maxillofacial functions, facial esthetics, and long-term development of ~260 million children in China. Beyond its physical manifestations, malocclusion also significantly influences the psycho-social well-being of these children. Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition, by mitigating the negative impact of abnormal environmental influences on the growth. Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development, ranging from fetal stages to the early permanent dentition phase. From an economic and societal standpoint, the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated, underlining its profound practical and social importance. This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children, emphasizing critical need for early treatment. It elaborates on corresponding core principles and fundamental approaches in early orthodontics, proposing comprehensive guidance for preventive and interceptive orthodontic treatment, serving as a reference for clinicians engaged in early orthodontic treatment.

Pediatric Le Fort, Zygomatic, and Naso-Orbito-Ethmoid Fractures

Fractures of the pediatric midface are infrequent, particularly in children in the primary dentition, due to the prominence of the upper face relative to the midface and mandible. With downward and forward growth of the face, there is an increasing frequency of midface injuries seen in children in the mixed and adult dentitions. Midface fracture patterns seen in young children are quite variable; those in children at or near skeletal maturity mimic patterns seen in adults. Non-displaced injuries can typically be managed with observation. Displaced fractures require treatment with appropriate reduction and fixation and longitudinal follow-up to evaluate growth.

Craniofacial Growth and Development: A Primer for the Facial Trauma Surgeon

Understanding craniofacial growth and development is important in the management of facial trauma in the growing pediatric patient. This manuscript is a review of craniofacial growth and development and clinical implications of pediatric facial fractures.

Epidemiology and Etiology of Facial Injuries in Children

Pediatric Trauma results in over 8 million emergency department visits and 11,000 deaths annually. Unintentional injuries continue to be the leader in morbidity and mortality in pediatric and adolescent populations in the United States. More than 10% of all visits to pediatric emergency rooms (ER) present with craniofacial injuries. The most common etiologies for facial injuries in children and adolescence are motor vehicle accidents, assault, accidental injuries, sports injuries, nonaccidental injuries (eg, child abuse) and penetrating injuries. In the United States, head trauma secondary to abuse is the leading cause of mortality among non-accidental trauma in this population.

Management of Soft Tissue Injuries in Children-A Comprehensive Review

Airway injury, Ocular injury and neurovascular tissue damage, burns is all a spectrum of pediatric soft tissue injury complex. Soft tissue injuries to the head and neck area in children are challenging to manage, because these injuries significantly affect the child's overall health and development. Management of such injuries requires a multidisciplinary approach involving surgical and nonsurgical interventions and close collaboration among health care professionals, parents, and caregivers. This article reviews the various causes of injuries, specific considerations for each region of the head and neck, and approaches to the surgical management of soft tissue injuries in pediatric patients, including surgical and adjuvant therapies. Specific anatomic regions reviewed include the scalp/forehead, periorbital region, nose, cheeks, lips, ears, and neck/airway.Laceration repair in the growing pediatric populations may require revisions in the future. Facial soft tissue injuries are prone to poor cosmesis as in many occasions as may be constrained by available surgical specialists, thus proper multispecialty team approach along with surgical alignment and symmetry should be considered comprehensively.

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 Impact of Payment Reform on Pediatric Craniofacial Fracture Care in Maryland

STUDY DESIGN

Retrospective, quasi-experimental difference-in-differences investigation.

OBJECTIVE

Pediatric craniofacial fractures are often associated with substantial morbidity and consumption of healthcare resources. Maryland's All Payer Model (APM) represents a unique case study of the health economics surrounding pediatric craniofacial fractures. The APM implemented global hospital budgets to disincentivize low-value care and encourage preventive, community-based efforts. The objective of this study was to investigate how this reform has impacted pediatric craniofacial fracture care in Maryland.

METHODS

Children (≤18 years) receiving inpatient craniofacial fracture-related care in Maryland between January, 2009 through December, 2016 were investigated. New Jersey was used for comparison. Data were abstracted from the Kid's Inpatient Database (Healthcare Cost and Utilization Project).

RESULTS

Between 2009-2016, 3,655 pediatric patients received inpatient care for craniofacial fractures in Maryland and New Jersey. Prior to APM implementation, around 20% of Maryland patients received care outside of urban teaching hospitals. After APM implementation, less than 6% of patients received care outside of urban teaching hospitals (p = 0.003). Implementation of the APM in Maryland also resulted in fewer pediatric craniofacial fracture admissions than New Jersey, though this only reached borderline significance (adjusted difference-in-differences estimate: -1.1 fewer admissions, 95% confidence interval: -2.1 to 0.0, p = 0.05). Inpatient costs for pediatric craniofacial care and mean did not change post-APM.

CONCLUSIONS

Maryland's APM consolidated pediatric craniofacial fracture inpatient care at urban, teaching hospitals. Inpatient costs and lengths of stay did not change after policy implementation, but overall admission rates decreased. Such considerations are important when considering national expansion of global hospital budgeting.

Radiographic evaluation in three dimensions of condylar fractures with closed treatment in children and adolescents

The study aimed at investigating a new three-dimensional classification of healing morphology in condylar fractures in children and adolescents after closed treatment, and establish its association with fracture type and clinical outcomes. The medical records of children and adolescents with condylar fracture were reviewed, retrospectively. The clinical outcomes were assessed by mandibular deviation during mouth opening, Helkimo anamnestic index (Ai), and Helkimo clinical dysfunction index (Di). The condylar healing morphology was evaluated through three-dimensional CT images after 1-2 years of follow-up. In total, 96 patients with 142 condylar fracture sites were included in the study. Condylar healing morphology was classified into three main patterns: unchanged (21.13%), spherical (62.68%), and irregular (16.19% - including the three subtypes triangular, L-shaped, and Y-shaped). There was a significant difference in the distribution of the three main healing patterns among various fracture types (p = 0.0227). Irregular patterns occurred more frequently in adolescents than in children. In unilateral fractures, no obvious association was found between condylar healing morphology and clinical outcomes, including mandibular deviation during mouth opening (p = 0.162), Ai (p = 0.0991) and Di (p = 0.25). Most patients healing in different condylar patterns reached a good clinical outcome after 1-2 years. Although the healing morphology of condylar fractures in children and adolescents remained abnormal, good clinical outcome was achieved over the 2-year follow-up. Therefore, closed treatment remains a good approach.

Maxillofacial trauma in children: Association between age and mandibular fracture site

PURPOSE

To describe the association between age and location of facial fractures in the pediatric population.

MATERIALS AND METHODS

A retrospective analysis of the Healthcare Cost and Utilization Project (HCUP) from the 2016 Kids' Inpatient Database (KID) in children aged ≤18 years was conducted. International Statistical Classification of Diseases, 10th Revision (ICD-10) codes were used to extract facial fracture diagnoses. Logistic regression was used to evaluate and compare the contribution of various demographic factors among patients who had different types of facial fractures.

RESULTS

A total of 5568 admitted patients were identified who sustained any type of facial bone fracture. Patients who had facial fractures were significantly more likely to be male (68.2% versus 31.8%; p<0.001) and were older with a mean age of 12.86 years (95% confidence interval [CI]: 12.72-12.99). Approximately one-third of patients with a facial fracture had a concomitant skull base or vault fracture. Maxillary fractures were seen in 30.9% of the cohort while mandibular fractures occurred in 36.9% of patients. The most common mandibular fracture site was the symphysis (N=574, 27.9% of all mandibular fractures). Condylar fractures were more common in younger children while angle fractures were more common in teenagers. Regression analysis found that age was the only significant contributor to the presence of a mandibular fracture (β=0.027, p<0.001) and race was the only significant contributor to maxillary fractures (β=-0.090, p<0.001).

CONCLUSIONS

Facial fractures increase in frequency with increasing age in children. The mandible was the most commonly fractured facial bone, with an age-related pattern in fracture location.

Characteristics of pediatric maxillofacial fractures in Kuwait: A single-center retrospective study

BACKGROUND

Pediatric maxillofacial fractures always present a challenge due to the unique nature of the facial skeleton anatomy and development. The aim of this study was to investigate the incidence, etiology, site of fracture, and management modalities of pediatric maxillofacial fractures in Kuwait.

METHODS

A retrospective cross-sectional study was conducted. The records of all pediatric patients who were diagnosed with maxillofacial fractures and admitted to one of the major hospitals in Kuwait between January 2007 and March 2020 were reviewed.

RESULTS

A total of 186 patients aged between 0 and 13 years old were included. An average of 13 patients was seen each year between 2007 and 2020. The leading cause of the pediatric maxillofacial trauma was road traffic accidents (RTA) that accounted for 38.2% of the patients followed by 22% falls from height (FFH). Male patients were more affected than females, with a ratio of 2.3:1. More than half of the children had mid-face fractures, of which 57% were in multiple sites. Conservative management was the main approach for 52.2% of the patients.

CONCLUSIONS

Pediatric maxillofacial fractures were mainly attributed to road traffic accidents in Kuwait. Mid-face bone fractures were reported more than mandibular fractures and were mostly managed conservatively.

Fore! A 10-year Analysis of Golf-related Facial Fractures

Over 30 million people in the United States play golf, which, while considered a low-impact sport, involves balls and clubs moving >100 miles/h (>160.93 km/h), creating potential for a significant facial trauma. The objective of this study was to characterize the epidemiology of golf-related facial fractures in the United States.

Sports-Related Pediatric Facial Trauma: Analysis of Facial Fracture Pattern and Concomitant Injuries

Objective  Sports-related injuries, such as facial fractures, are potentially debilitating and may lead to long-term functional and aesthetic deficits in a pediatric patient. In this study, we analyze sports-related facial fractures in the urban pediatric population in an effort to characterize patterns of injury and improve management strategies and outcomes.

Methods  Retrospective chart review was performed for all facial fractures resulting from sports injuries in the pediatric population at a level-1 trauma center (University Hospital, Newark, NJ).

Results  Seventeen pediatric patients were identified as having sustained a fracture of the facial skeleton due to sports injury. Mean age was 13.9 years old. A total of 29 fractures were identified. Most common fracture sites included the orbit ( n  = 12), mandible ( n  = 5), nasal bone ( n  = 5), and zygomaticomaxillary complex ( n  = 3). The most common concomitant injuries included skull fracture ( n  = 3), intracranial hemorrhage ( n  = 4), and traumatic brain injury ( n  = 4). One patient was intubated upon arrival to the emergency department. Hospital admission was required in 13 patients, 4 of which were admitted to an intensive care setting. Nine patients required operative intervention. Mean length of hospital stay was 2.4 days. No patients were expired.

Conclusions  Sports-related facial fractures are potentially debilitating injuries in the pediatric population. Analysis of fracture pattern and concomitant injuries is imperative to develop effective management strategies and prevention techniques.

Oral and cranio-maxillofacial trauma in children and adolescents in an emergency setting at a Brazilian hospital

BACKGROUND/AIMS

Very few studies have been performed to evaluate cranio-maxillofacial trauma diagnosed in hospitals in children and adolescents. The aim of this study was to perform an analysis of oral and cranio-maxillofacial trauma in the aforementioned population.

MATERIALS AND METHODS

A hospital-based retrospective study, which reviewed 1438 patient records, was conducted at the "Teresina Emergency Hospital", Brazil. Data regarding demographics, day of the week on which trauma occurred, type of injury, etiology, anatomic trauma site, time of hospital admission, and associated comorbidities (or injuries) were collected.

RESULTS

There were 1092 (75.9%) males and 346 (24.1%) females. The largest group was adolescents aged between 13 and 18 years (956, 66.5%). The majority lived in urban areas (69%). Trauma occurred most frequently during the week. The most prevalent etiology was road traffic accidents involving motorcycles (771, 53.6%) causing facial and skull fractures (598, 41%). The most prevalent soft tissue lesions were facial abrasions (49%), followed by injuries to the cheek (16.7%). Comorbidities associated with craniofacial trauma were present in 82%, with complications from traumatic brain injuries being the most prevalent (65.6%) Dental trauma was recorded in only 81 cases (5.6%).

CONCLUSION

Male adolescents living in urban areas were most affected by craniofacial trauma. The most common cause was road traffic accidents involving motorcycles, resulting in facial and skull fractures. Complications from traumatic brain injuries were the most common associated injuries.

Bioabsorbable plating in the treatment of pediatric clavicle fractures: A biomechanical and clinical analysis

BACKGROUND

Classic implants for operative intervention of mid-shaft clavicle fractures in adolescents can become symptomatic, requiring removal. This study compares 1) biomechanical properties and 2) clinical outcomes in adolescents of mid-shaft clavicle fracture fixation with bioabsorbable versus metal implants.

METHODS

Six synthetic clavicles with mid-shaft fractures underwent bioabsorbable plating. A testing frame applied 10 non-destructive torsion and 10 axial compression cycles, followed by cantilever bending to failure. Stiffness was calculated; maximum failure load and failure mode were recorded. Results were compared to previous data for locked metal constructs. Retrospective review of surgically treated clavicle fractures over three years included functional and radiographic outcomes.

FINDINGS

Bioabsorbable plates had lower torsional stiffness (P < 0.001) and maximum cantilever load (P < 0.0001) than locked metal plates. There was no significant difference in compression stiffness (P = 0.2) or cantilever bending stiffness (P = 0.4). Primary failure of metal plates was screw pull-out compared to plate bending in bioabsorbable constructs. Seven patients with bioabsorbable implants were included. All patients with bioabsorbable constructs achieved radiographic union, but 71% lost reduction. Despite fracture angulation, all achieved normal shoulder function after one year determined by QuickDASH evaluation. None required a second surgery.

INTERPRETATION

Bioabsorbable implants had lower torsional stiffness and cantilever failure load, but comparable compression stiffness to metal implants. Bioabsorbable implants failed via gradual bending versus the catastrophic failure seen in metal implants. The clinical review allows understanding of the sequelae of this lower failure load of bioabsorbable plates where their use allowed in fracture displacement, yet achievement of ultimate radiographic union and acceptable functional outcomes.
