Management of Pediatric Mandibular Fractures Using Resorbable Plates:

Enhancing Biodegradable Bone Plate Performance: Stereocomplex Polylactic Acid for Improved Mechanical Properties and Near-Infrared Transparency

The use of biodegradable materials in bone plates offers remarkable advantages; however, their application in bone fixation is limited by their brittleness. Moreover, treatments tailored to patient conditions are needed in orthopedics. In this study, bone plates were fabricated with stereocomplex polylactic acid (scPLA) and the effects of poly(d-lactic acid) molecular weight and scPLA blending ratios were analyzed. Although modulus values of poly(l-lactic acid) (PLLA) and scPLA were similar, strain resistance improved at higher scPLA proportions. The enhanced elongation was owing to the presence of tie molecules within the scPLA as opposed to single PLA chains. The fabricated scPLA bone plates exhibited improved mechanical properties and transparency in the optical and near-infrared ranges. scPLA was characterized by a smaller crystallite size. These properties of scPLA combined with its biocompatibility indicate potential for various diagnostic and therapeutic orthopedic applications. Comparisons with commercial PLLA-based bone plates show no significant differences in in vivo bone-healing ability.

Surgical management of naso-orbito-ethmoidal fractures: a systematic review

OBJECTIVE

Naso-orbito-ethmoidal fractures (NOE) fractures are uncommon but critical injuries. This review aims to investigate the patient factors, procedural factors, and postoperative outcomes associated with the surgical management of NOE fractures.

STUDY DESIGN

PubMed and Scopus databases were systematically searched between 1993 and 2023 using the search strategy "(naso-orbito-ethmoidal OR nasoethmoid OR nasoorbitoethmoidal) AND fracture." Articles reporting clinical studies investigating the surgical management of NOE fractures were included. Articles that were duplicates, non-English, or non-full text; reported an unclear age range; reported insufficient data; and/or reported on a sample size less than 10 were excluded. Data on patient factors, procedural factors, and postoperative outcomes were extracted.

RESULTS

Of the 412 articles identified, 6 eligible articles (retrospective case series) representing 95 adult cases and 84 pediatric cases were included. The mean ages were 29.0 and 10.2 years, respectively. Most cases were male (65.3%; 73.9%). Motor vehicle accidents were the most common mechanism of injury (79.2% and 50.0%, respectively). Coronal incision was the most common approach. Epiphora (n = 33) and scar problems (n = 21) were the most common complications in adult and pediatric cases, respectively.

CONCLUSIONS

Further robust longitudinal studies with a clear description of fracture classification and surgical timing would be helpful. Gaps in knowledge include concomitant injuries, digitally-assisted applications, and risk factors for adverse outcomes.

The Role of Orthodontics in the Management of Maxillofacial Fractures in Children: A Review on Contemporary Approaches

Maxillofacial fractures present complex challenges requiring effective orthodontic management to restore function and aesthetics. This review explores various orthodontic techniques, including fixed braces, maxillomandibular fixation (MMF), functional orthodontic therapy (FOT), and acrylic splints, emphasizing their roles in stabilizing fractures and promoting healing. The management of condylar fractures is discussed, highlighting the benefits of early intervention with functional appliances to facilitate condylar remodeling in children and adolescents. Additionally, the review covers splinting methods for dental and dentoalveolar fractures and the use of open reduction internal fixation (ORIF) for maxillary fractures. It addresses the complications and challenges of fracture management, the need for a multidisciplinary approach, and the limitations of current studies. Future directions include the use of advanced technologies such as virtual surgical planning (VSP) and 3D printing to enhance treatment precision and outcomes. This review provides a comprehensive overview of orthodontic strategies for maxillofacial fractures, offering insights into clinical applications and future advancements.

Children mandibular fractures: Epidemiological and anatomo-clinical aspects

Introduction

Maxillofacial trauma in children is uncommon, accounting for between 1 % and 14 % of all facial trauma in the general population.

Objective

To describe the epidemiological and anatomical-clinical aspects of mandibular fractures in children.

Material and method

This was a retrospective descriptive cross-sectional study with non-probabilistic accidental sampling. It took place in the maxillofacial surgery and stomatology department of Cocody University Hospital in the Republic of Côte d'Ivoire, over a 20-year period (2000-2019). The study population consisted of patients aged 0-16 years admitted to our department for a mandibular fracture. At the end of this study, we identified 58 patients. Data was entered using Excel 2016. Tables and graphs were processed using Excel version 2016.

Results

we have identified 58 patients. The mean age of patients was 9.35 ± 2.1 years, with extremes of 1 and 16 years, and a sex ratio of 2,22 in favouring men. The 6-12 age group was the most affected (n: 34 cases or 60.35 %). Soft tissue wounds were present in all our patients, followed by peri-mandibular swelling (n: 37 cases or 63.79 %) and disorders of the dental articulation (n: 28 cases or 48.2 %). Condylar fractures were the most frequent (46.87 %).Mandibular fracture lines were uni-focal in 75 % of cases. These fractures were associated with other facial lesions in 48.28 % of cases and with extra-facial lesions in 34.48 % of cases.

Conclusion

Mandibular fractures are common in maxillofacial trauma in children. Condylar fractures are the most common, almost always associated with chin injuries. Hence the importance of a systematic examination of the mandibular condyles.

Complications of Mandibular Fracture Repair

Mandible fracture management has evolved dramatically. Therefore, the variety of surgical complications associated with mandibular fractures, and their incidences, have continued to change as well. This article aims to assess the most common and most concerning complications that can occur secondary to management of mandibular fractures by examining categories of complication types. This article also explores factors and techniques associated with reduced rates of complications as well as the management of complications.

Pediatric Panfacial Fractures

Pediatric panfacial trauma is a rare occurrence with poorly understood implications for the growing child. Treatment algorithms largely mirror adult panfacial protocols with notable exceptions including augmented healing and remodeling capacities that favor nonoperative management, limited exposure to avoid disruption of osseous suture and synchondroses growth centers, and creative fracture fixation techniques in the setting of an immature craniomaxillofacial skeleton. The following article provides a review of our institutional philosophy in the management of these challenges injuries with important anatomic, epidemiologic, examination, sequencing, and postoperative considerations.

Pediatric Maxillofacial Trauma: Insights into Diagnosis and Treatment of Mandibular Fractures in Pediatric Patients

Aim

To assess the diagnostic and therapeutic approaches in pediatric mandibular fractures with regards to fracture pattern and localization.

Patients and methods

This retrospective study included patients under the age of 17 years that presented to the Department of Oral and Maxillofacial Surgery at Charité-Universitätsmedizin Berlin with mandibular fractures over an 11-year long period (2010-2020). Medical records were analyzed for age, gender, injury mechanism, clinical presentation, imaging modalities, fracture pattern, and fracture management. Statistical analyses included descriptive statistics, normality testing, and Mann-Whitney U tests.

Results

A total of 91 pediatric patients (23 females and 68 males) presented with mandibular fractures. The majority of mandibular fractures occurred in patients aged 13-16 years (67.0%, n = 61). The main causes were activities of daily life (34.1%), followed by assault (25.3%). Malocclusion and pain upon mandibular joint compression were documented in 72.5% and 51.7% of patients, respectively. The most frequently applied radiological diagnostic tool was a panoramic X-ray (49.5%). The main fracture patterns were single (42.9%) and double fractures (48.4%). An age-adapted surgical approach using open reduction and internal fixation (ORIF) was the most frequent management (61.5%). A conservative approach was favored in cases of condylar head fractures. Resorbable plates were used in eight cases of ORIF (8.8%).

Conclusion

Treatment regimens should be carefully selected based on the unique anatomy of the pediatric patient with regards to centers of growth and dentition phase, to restore stomatognathic function and to maintain adequate skeletal growth and eruption of teeth.

Clinical significance

This study illustrates the challenges of mandibular fracture management in the pediatric patient.

Orthodontic Approaches in the Management of Mandibular Fractures: A Scoping Review

Non-surgical approaches have been proposed in the management of mandibular fractures, especially in children, but there is a lack of clear guidelines on the clinical indications of conservative approaches. The aim of this scoping review is to provide the available evidence of the role of the orthodontist in the management of mandibular fractures. The PRISMA-ScR guidelines were followed to select eligible articles from the PubMed, Scopus, and Web of Science databases according to precise inclusion criteria. The research questions were formulated as follows: "what is the scientific evidence concerning the rule of orthodontists in the management of mandibular fractures" and "the preferential use of the direct bonding technique with orthodontic brackets rather than rigid arch bars"? Seventeen articles were included. Five articles presented the use of removable acrylic splints or functional appliances, six articles concerned the employment of cemented acrylic or rigid splints, and six articles described the management of mandibular fractures in adults and children using orthodontic brackets or mini-screws. Most of these techniques have been employed in children and growing subjects, while fewer data were available regarding conservative treatments in adults. Preliminary evidence suggests that condylar and some minor parasymphyseal fractures in children may be managed with conservative approaches. In adults, minor condylar and stable body mandibular fractures with minimal displacement have been reduced similarly. However, there are no sufficient elements that could suggest the preferential use of orthodontic brackets over rigid arch bars in adults. Further randomized and non-randomized clinical trials with long follow-ups will be needed to better define the clinical indications of the orthodontic approaches in the management of mandibular fractures based on severity, location, and age.

Resorbable Versus Titanium Rigid Fixation for Pediatric Mandibular Fractures: A Systematic Review, Institutional Experience and Comparative Analysis

Study Design

Pediatric mandible fractures mandate special consideration because of unerupted teeth, mixed dentition, facial growth and the inability to tolerate maxillomandibular fixation. No consensus exists as to whether resorbable or titanium plating systems are superior with regards to clinical outcomes.

Objective

This study aims to systematically review and compare the outcomes of both material types in the treatment of pediatric mandible fractures.

Methods

After PROSPERO registration, studies from 1990-2020 publishing on outcomes of ORIF of pediatric mandible fractures were systematically reviewed according to PRISMA guidelines. An additional retrospective review was conducted at a pediatric level 1 trauma center.

Results

1,144 patients met inclusion criteria (30.5% resorbable vs. 69.5% titanium). Total complication rate was 13%, and 10% required a second, unplanned operation. Complication rates in the titanium and resorbable groups were not significantly different (14% vs. 10%; P = 0.07), and titanium hardware was more frequently removed on an elective basis (P < 0.001). Condylar/sub-condylar fractures were more often treated with resorbable hardware (P = 0.01); whereas angle fractures were more often treated with titanium hardware (P < 0.001). Within both cohorts, fracture type did not increase the risk of complications, and comparison between groups by anatomic level did not demonstrate any significant difference in complications.

Conclusions

Pediatric mandible fractures requiring ORIF are rare, and hardware-specific outcomes data is scarce. This study suggests that titanium and resorbable plating systems are equally safe, but titanium hardware often requires surgical removal. Surgical approach should be tailored by fracture anatomy, age-related concerns and surgeon preference.

Customizable interdental splinting for repair of pediatric mandibular fractures in children with mixed dentition: A novel technique

OBJECTIVE

Repair of pediatric mandibular fractures (PMFs) can be challenging due to the lack of permanent dentition for immobilization, and the presence of unerupted teeth and growth plates in the mandible limiting the space for fixation. Interdental splinting (IDS) has been advocated to provide temporary fixation without the need for mandibular plating; however, there is sparse description of the surgical methodology, and data on long term outcomes are even more limited. The aim of this study is to present our technique and outcomes using a novel technique for IDS repair of pediatric mandible fractures.

STUDY DESIGN

Observational retrospective chart review.

SETTING

Tertiary care pediatric hospital.

SUBJECTS AND METHODS

Pediatric patients requiring operative repair for mandibular fracture at our tertiary care institution between 2004 and 2021 were included. Patients over 18 years of age, those who died due to associated injuries, or those who underwent non-IDS repairs were excluded. Subjects with at least 3 months of follow-up were assessed for efficacy of surgical repair and short-term adverse outcomes, and at least 1 year for long-term adverse events. Descriptive statistics were obtained.

RESULTS

Twenty-three children were included in the study with an average age of 7.4 years (range 2-17 years). Fifty-two percent (52.2%) were female. The most common fracture site was the condyle, occurring in 16 children (70%). The indication for operative repair in all cases was malocclusion. The average duration of maxillomandibular fixation (MMF) with the novel IDS was 21 days (range 12-42 days). The average length of follow up was 1.6 years (range 3 months-11 years). All children had restored, functional occlusion at follow up with none requiring further orthodontic or dental intervention. Three children of the total cohort (13.0%) had prolonged hospitalization beyond 48 h for poor oral intake. Five children (21.7%) experienced minor long-term complications including persistent temporomandibular joint pain (n = 1, 4.3%), infection (n = 2, 8.7%), hypertrophic scar (n = 1, 4.3%) and exposure of hardware (n = 1, 4.3%).

CONCLUSION

PMFs resulting in malocclusion are safely and effectively managed with operative repair utilizing a customizable IDS, with few observed short- and long-term complications.

Pediatric Facial Fractures

Facial trauma is common in the pediatric population with most cases involving the soft tissue or dentoalveolar structures. Although facial fractures are relatively rare in children compared with adults, they are often associated with severe injury and can cause significant morbidity and disability. Fractures of the pediatric craniomaxillofacial skeleton must be managed with consideration for psychosocial, anatomical, growth and functional differences compared with the adult population. Although conservative management is more common in children, displaced fractures that will not self-correct with compensatory growth require accurate and stable reduction to prevent fixed abnormalities in form and function.

#facialtraumasurgery: Educational Content of Instagram as a Social Media Source for Facial Trauma Surgery

ABSTRACT

With an uprising influence of social media platforms like Instagram during the last decade, medical and healthcare related posts have accumulated majorly. In particular the head and face characterizes and signifies each individual's human character, which may be the reason why numerous posts are shared on social media platforms. The purpose of this investigation was to assess the content associated with facial trauma surgery and evaluate its educational quality.The authors performed a retrospective investigation on 550 Instagram posts by #facialtraumasurgery due to number of "likes," comments, type of post, language, its purpose, and source. Furthermore, posts were evaluated due to their educational quality by 3 examiners of different educational levels.The majority of posts showed 0 to 50 "likes" and 0 to 5 comments in English language. The major post type were single photographs (289; 52.5%), multiple photographs (188; 34.2%), videos (73; 13.3%) and predominantly case reports (233; 42.4%). The source was 322 (58.5%) posts by surgeons, followed by 185 (33.6%) clinic posts. Only 10% to 18% of the posts were rated "excellent." Interrater reliability between all 3 examiners presented a high concordance with 89% (P = 0.000).Our study presents an analysis of quantity and quality of social media content according to facial trauma surgery. It supports the deduction that most of the content on Instagram is shared by patients and unclear sources and thus is limited informative. Nevertheless, influence of social media on medical information is increasing and practitioners have to face its effect on their patients.

Biomaterials in Craniomaxillofacial Reconstruction: Past, Present, and Future

ABSTRACT

Deformity and tissue loss involving the craniomaxillofacial region occurs frequently as a result of trauma, oncologic resection, or a congenital malformation. In order to maximize the patient's quality of life, reconstruction of the craniomaxillofacial skeleton must seek to restore aesthetics as well as function. Advances in diagnostic technology, surgical technique, instrumentation, and innovative biomaterials used have transformed the way reconstructive surgeons approach their patients' needs. From the advent of alloplastic reconstruction, surgeons have sought the ideal material for use in craniomaxillofacial surgery. Substances such as metals, ceramics, glasses, and more recently resorbable polymers and bioactive materials have all been utilized.While autologous bone has remained widely-favored and the gold standard, synthetic alternatives remain a necessity when autologous reconstruction is not readily available. Today, alloplastic material, autografting via microvascular tissue transfer, hormone and growth factor-induced bone formation, and computer-aided design and manufacturing of biocompatible implants represent only a fraction of a wide range of options used in the reconstruction of the craniomaxillofacial skeleton. We present a brief review of the materials used in the repair of deformities of the craniomaxillofacial skeleton as well as a look into the potential future direction of the field.

Mandible Fractures Associated With the Introduction of an E-Scooter-Sharing System

ABSTRACT

With the introduction of an e-scooter-sharing system in Germany, standing electric scooters became popular modes of transportation in many urban areas. But the increase in popularity has resulted in an increase in traumatic injuries associated with e-scooter accidents. The purpose of this investigation was to determine the common fracture pattern of patients with mandible fractures as a result of an electric scooter accident. The authors performed a retrospective investigation of 52 patients who were admitted to the trauma unit of an oral and maxillofacial department from June until November 2019 with a fracture of the mandible. Our study investigated the first 6 months of e-scooter sharing system in a major city with more than 1 million inhabitants. Our cohort consists of 52 patients, 38 males, and 14 females with a mean age of 37 years. E-scooter related mandible fractures were with 21% the third biggest group, after physical assault and falls. 45% of these patients were intoxicated by alcohol. Furthermore, the majority of e-scooter patients presented more than one fracture of the mandible (73%). For our cohort, a typical combination of a symphysis or body fracture and bilateral affected ramus and/or condyle was the prevalent recorded fracture combination (55%) of e-scooter related traumata. Small scooter wheels, a speed of 15 miles or 20 kilometers per hour and the individual clinging to the handlebar falling predestinate these vehicles for accidents with craniofacial trauma. Among all cranio-facial traumas mandible fractures were mostly documented for e-scooter accidents. The severity of e-scooter related mandible fractures and their fracture pattern should be recognized by trauma units.

Foreign Body Reaction to Poly-D-L-Lactic Acid Resorbable Plates Used in Craniofacial Surgery

Resorbable surgical materials are often used in the pediatric population to provide fixation in the growing skeleton. Although foreign body reactions to poly-D-L-lactic acid (PDLLA) plates and screws have been previously reported in other fields, to date PDLLA polymers have been well-tolerated in the setting of craniofacial surgery. The authors report a case of a previously healthy 4-month-old patient with Crouzon syndrome who underwent a frontal-orbital advancement with resorbable PDLLA plates and screws and subsequently experienced extensive foreign body reactions and wound healing complications.

Facial Fractures and Mixed Dentition - What Are the Implications of Dentition Status in Pediatric Facial Fracture Management?

INTRODUCTION

The stage of maturation of the pediatric facial skeleton at the time of injury has a significant impact on both facial fracture patterns and management strategies. For instance, the relative prominence of the pediatric cranium during the early years of life affords protection to the structures of the midface, whereas delayed aeration of the frontal sinuses may predispose younger patients to frontal bone fractures. The dentition status of a pediatric patient may have similar implications in the setting of facial fracture. In this study, the authors examine the effect of dentition status on facial fracture patterns and management strategies at an urban, level 1 trauma center.

METHODS

A retrospective chart review was performed for all cases of facial fracture occurring in the pediatric patient population at a level 1 trauma center (University Hospital in Newark, NJ) between 2002 and 2014. A database including patient demographics, facial fracture, and concomitant injury patterns, and operative management data was constructed and analyzed.

RESULTS

A total of 72 patients with mixed dentition met inclusion criteria for our study and were compared against patients with primary (n = 35) and permanent (n = 349) dentition. The mean age at presentation was 9.2 years, with a male predominance of 68%. The most common fracture etiology was pedestrian struck accident (n = 23), fall (n = 21), motor vehicle collision (n = 12), and assault (n = 9). The most frequently identified facial fractures were that of the orbit (n = 31), mandible (n = 21), nasal bone (n = 19), and frontal sinus (n = 14). Additionally, 8 Le Fort and 4 nasoorbitoethmoid fractures were identified. Twenty-one patients (29%) required operative management for 1 or more facial fractures. Operative intervention was required in 38% of mandibular fractures, with 6 patients requiring only maxillomandibular fixation and 2 requiring open reduction and internal fixation with titanium plating. Nine cases of orbital fracture (29%) were managed operatively - 4 with absorbable plates, 3 with Medpor implants, and 8 with titanium plating. Management of all nasal fractures requiring operative intervention was accomplished through closed reduction. Concomitant injuries included traumatic brain injury (TBI) (n = 35), skull fracture (n = 24), intracranial hemorrhage (ICH) (n = 20), and long bone fracture (n = 12). Seventeen patients required admission to the intensive care unit. Patients with mixed dentition were significantly more likely to sustain frontal sinus and Le Fort fractures (P < 0.01), as well as skull fracture, ICH, and TBI (P < 0.01) as compared to those with permanent dentition.

CONCLUSIONS

The dentition status of a pediatric patient may have significant implications in both patterns of injury and operative management strategies in the setting of acute facial trauma. Our study finds that Le Fort and frontal sinus fractures were significantly more common in patients with mixed dentition. Severe concomitant injuries such as ICH and TBI were also significantly more likely in this cohort. A patient's dentition status may also play a role in the decision for ridged fixation of mandibular and orbital fractures, as well as the method of maxillomandibular fixation in maxillary and mandibular alveolar fracture.

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.
