Management of Pediatric Maxillary Fractures

Surgical management of maxillary trauma in pediatric special needs patient using modified cap splint

Pediatric maxillofacial trauma is a rare entity, which is primarily the reason for an individual surgeon's inexperience in managing such injuries. More so, maxillary injuries are infrequent. Pediatric maxillofacial injuries are usually a result of blunt force trauma such as falls, motor vehicle accidents, bicycle injuries, sports-related injuries, assault, and child abuse. The atypical pattern of facial injuries in the pediatric population necessitates each surgeon to approach individual cases with a unique and innovative technique of management, while still following the basic principles of surgical management of maxillofacial injuries. Since facial trauma and surgical interventions both have the potential to lead to disturbance in growth and development, management should be as conservative as possible. The foundation of any surgical intervention must be developed keeping in perspective, the future growth, and development of dentofacial structures. Pediatric facial trauma management is in itself a disconcerting situation for a maxillofacial surgeon, but when a special needs child is involved it becomes an even more perplex decision. We present a case of maxillary trauma in a pediatric patient with global developmental delay, the treatment dilemma, and a review of current literature.

Assessment of Panfacial Fractures in the Pediatric Population

PURPOSE

Management of panfacial fractures is critical and often difficult in adults; however, there is little to no literature regarding these fractures in the pediatric population. In this study, we present our experience to provide insight and further investigation regarding prevention and management strategies within the pediatric population.

PATIENTS AND METHODS

We performed a retrospective chart review of all panfacial fractures in the pediatric population between 2002 and 2014 treated at an urban, level 1 trauma center (University Hospital, Newark, NJ). Data including patient demographic characteristics, mechanisms of injury, locations of fractures, concomitant injuries, and surgical management strategies were collected.

RESULTS

We identified 82 patients aged 18 years or younger who had sustained a panfacial fracture. The mean age at the time of injury was 12.9 years, with a male predominance of 64.9%. A total of 335 fractures were identified on radiologic imaging. The most common etiologies were motor vehicle accidents and pedestrians being struck. Orbital, frontal sinus, nasal, and zygoma fractures were the most common fractures. The mean score on the Glasgow Coma Scale on arrival was 12.0. A total of 29 patients were intubated on arrival-or before arrival-at the trauma bay. A surgical airway was required in 9 patients. The most common concomitant injuries were traumatic brain injury, intracranial hemorrhage, and skull fracture. Surgical repair was required in 38 patients. The cephalic-to-caudal approach was used most, followed by caudal to cephalic, medial to lateral, and lateral to medial. Within a year of the initial surgical procedure, 4 patients underwent reoperations for complications. Four patients died.

CONCLUSIONS

Pediatric panfacial fractures are rare occurrences; however, the impact of these injuries can be devastating, with concomitant life-threatening injuries and complications. Given the lack of literature, as well as the preventable nature of these injuries, we hope this study can address primary prevention strategies and provide insight toward the management and characteristics of these fractures.

Analysis of Pediatric Maxillofacial Fractures Requiring Operative Treatment: Characteristics, Management, and Outcomes

Maxillofacial fractures in pediatric trauma patients require significant force and frequently are associated with concomitant injuries. The anatomic and developmental differences between the adult and child that impact patterns of injury also affect management and outcomes. The aim of this study was to analyze fracture location, mechanism, concomitant injuries as well as methods of surgical treatment and outcomes, to improve management of this patient population. A retrospective review was conducted of pediatric patients with maxillofacial fractures presenting to a level-1 trauma center during an 8-year span. Only patients requiring surgical intervention, 204, were included in this study. Data pertaining to the location of injury, mechanism, associated injuries, surgical treatment, outcomes, and complications were analyzed. The most common fracture location was the mandible (36.3%), then the nasal bone (35.3%), followed by the tripod fracture (10.8%). A total of 30.7% of patients were involved in motor vehicle accidents, with the next most common mechanisms being sports (24.4%), and assault (13.7%). A total of 46% of the patients sustained concomitant injuries, with the majority involving cerebral trauma (14.7%) or the extremities (9.3%). Total 75.4% of all fractures, excluding the nose, were treated with open reduction and internal fixation (ORIF). Our complication rate was 11.2%. Pediatric craniofacial trauma remains a frequent presentation to the emergency department of trauma centers. Facial fracture patterns and mechanism of trauma observed in the pediatric population presenting to this facility are consistent with incidences reported in the literature. Knowledge of treatment options and potential complications is an important tool in the management of the pediatric trauma patient.

Pediatric frontal sinus fractures: outcomes and treatment algorithm

Pediatric frontal sinus fractures are a rare clinical entity. Owing to the large amount of force required to fracture the frontal sinus, it is often associated with severe intracranial and craniofacial injuries. The treatment of frontal sinus fractures is controversial, with many different established algorithms based mainly on the adult population. The authors present their experience with pediatric frontal sinus fractures; they also present a treatment algorithm. A retrospective review of the Cincinnati Children's Hospital Medical Center trauma database was performed. From 1998 to 2010, the authors identified patients between the ages of 0 and 18 with frontal sinus fractures and analyzed demographics, fracture pattern, associated injuries, methods of treatment, and complications. Descriptive statistics and univariate analyses were performed.A total of 39 patients were included in the study with a mean follow-up of 31.2 months. Fractures of the anterior and posterior table with displacement greater than one table width were significantly associated with higher hospital costs, higher velocity mechanism of injuries, lower Glasgow Coma Scale scores, nasofrontal outflow tract (NFOT) involvement, and cerebrospinal fluid leak. There were no differences in short- and long-term complications. Additionally, these patients were more likely to be treated surgically in the form of obliteration or cranialization.Patients without NFOT involvement can be managed with observation only. Patients with NFOT involvement or persistent cerebrospinal fluid leak should be treated with obliteration or cranialization, respectively, to reduce the risk of severe complications.

Pediatric craniomaxillofacial trauma

Trauma is a leading cause of death in children. The pediatric facial skeleton goes through progressive development and major changes, including change in the size ratio of the cranium to the face; change in the ratio of facial soft tissue to bone, and pneumatization of the sinuses. The main goal of maxillofacial fracture repair is to reestablish normal or preinjury structure and function. Follow-up is typically recommended until children reach skeletal maturity as trauma may affect growth of the facial skeleton. Problems not obvious immediately after the injury may become an issue later, and secondary surgery might be needed to address such issues.

Incidence and pattern of maxillofacial fractures in children and adolescents: a 10 years retrospective cohort study

OBJECTIVE

The purpose of this study was to evaluate and compare the demographic characteristics of maxillofacial fractures between children and adolescents.

METHODS

The sample was composed of all children (less than 12 years) and adolescents (between 13 and 18 years old) who presented with maxillofacial fractures during a 10-year period (2000-2009). The age, gender, time of injury, mechanism of trauma, location and pattern of fracture, associated injuries, and treatment methods were recorded and analyzed. Data analysis included Chi-Square test, Fisher exact test. p less than 0.05 was considered significant.

RESULTS

Seventy-nine children (male-to-female ratio, 1.63:1) and 113 adolescents (male-to-female ratio, 3.52:1) sustained 389 maxillofacial fractures. Children were more involved in falls compared to adolescents (44.3% versus 23.9%, p=0.003), while adolescents sustained more assault-related injuries (13.3% versus 2.5%, p=0.010) and motorcycle accidents (22.1% versus 8.9%, p=0.015) compared to children. Children suffered mandibular fractures proportionally higher than adolescents (93.1% versus 64.5%, p<0.001). Adolescents sustained mid-facial fractures more frequently than children (35.5% versus 6.9%, p<0.001). Severe facial fractures occurred more in adolescents compared to children (35.4% versus 14.1%, p=0.001). Open reduction was done more in adolescents than in children (92.3% versus 74.6%, p<0.001).

CONCLUSIONS

The incidence and pattern of maxillofacial fractures in children were remarkably different from that in adolescents. Preventive measures and treatment plan should be designed with differences between the two groups in mind.

Management of maxillary alveolar bone fracture and severely intruded maxillary central incisor: report of a case

An 11-year-old male who injured his maxilla and right maxillary central incisor and lip during a fall was presented to our hospital. His lower lip and upper gingiva were lacerated with swelling and epistaxis, and he had a maxillary alveolar bone fracture and severe intrusion of the right maxillary central incisor, which had penetrated the floor of the nasal cavity with avulsion. Under local anesthesia, we repositioned the incisor and bone segment and fixed them with a titanium micromesh plate and self-tapping screws and splints. The incisor was also treated by root canal 3 days after the operation and was restored with a crown. We performed root canal filling 1 month later. Five months later, the plate and screws were removed. In prognosis of our case, no symptoms of inflammatory root resorption or ankylosis have observed for more than 1 year and 6 months of follow up based on both clinical and radiographic findings.
