Open Reduction, Internal Fixation of Isolated Mandible Angle Fractures in Growing Children

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.

Indications and complications regarding titanium osteosynthesis in pediatric maxillofacial trauma: A scoping review and critical appraisal

With the advent of biodegradable osteosynthesis material, titanium osteosynthesis for ORIF in pediatric maxillofacial trauma is not as indisputable as before. The aim of this study was to conduct a scoping review to assess the indications, complications of ORIF with titanium osteosynthesis material in pediatric maxillofacial trauma. A systematic search was conducted in PubMed/MEDLINE, Embase, Web of Science, Cochrane Library, gray literature (ICTRP and clinicaltrials.gov) for studies published until April 2022. 3436 studies were screened and finally 13 articles, compromising a sample of 340 pediatric patients were included after full text reading. Reported complications were infection (6.5% of population), malocclusion (5% of population) and dental maleruption (8% of population). Influence on future growth could not be assessed due to short and heterogeneous follow-up periods. Eight of the thirteen studies concluded to a positive and predictable outcome using titanium ORIF for displaced/complex pediatric maxillofacial fractures. Results of this review suggest that titanium ORIF for maxillofacial fractures in the pediatric population is a reliable treatment. The surgeon must be committed to following these patients longitudinally. Interpreting the results should, however, be done with great care, as most articles have a medium to high risk of bias and limited follow-up.

Pediatric mandibular fractures: Surgical management and outcomes in the deciduous, mixed and permanent dentitions

BACKGROUND/AIM

Mandibular fractures are the most frequent type of pediatric facial traumatic injury, but their treatment remains controversial. The aim of this retrospective study was to analyze the surgical treatment and long-term outcomes of dentate mandibular fractures in children and adolescents.

MATERIAL AND METHODS

Patients with mandibular fractures in the dentate area who were surgically treated in the period from January 1, 2001, to December 31, 2020, were included. The following data were collected: age, gender, cause and mechanism of injury, fracture site and type, associated maxillofacial fractures, the timing of surgical treatment, Facial Injury Severity Scale (FISS) score, surgical approach, number and thickness of plates, hospitalization stay and outcome. Patients were divided into three groups: deciduous (≤6 years, group A), mixed (7-12 years, group B), and permanent (13-18 years, group C) dentitions. Statistical analyses were performed using SPSS software.

RESULTS

During the study 91 patients (male: female ratio, 3.8:1), 4 in group A, 12 in group B, and 75 in group C, with 65 single and 52 double fractures were included. An intraoral approach was used in 87% of patients. In group C, 90% of patients were treated with fixation schemes consistent with those suggested in the literature for adults, versus 75% in groups A and B. Median follow-up time was 20 months. No tooth germ injury or facial asymmetry was observed and only six group C patients had post-operative malocclusions. Hardware removal occurred in 22% of the patients.

CONCLUSIONS

This 20-year retrospective study shows that open reduction and internal fixation of pediatric dentate mandibular fractures caused no tooth germ damage or disturbances of mandibular growth in any dentition stage. Internal fixation schemes were similar to those used for adults, although it was necessary to adapt hardware size and position according to tooth and patient age.

Outcomes in Pediatric Maxillofacial Reconstruction With Vascularized Fibular Flaps: A Systematic Review

BACKGROUND

The purpose of this study was to examine the complications and outcomes after maxillofacial reconstruction using the free fibular flap in the pediatric population.

METHODS

A systematic review and descriptive analysis were conducted using data variables, including study characteristics; patient characteristics; postoperative complications (major and minor); surgical revision; and dental rehabilitation.

RESULTS

The systematic review resulted in 1622 articles, 55 of which met inclusion criteria for this study. The 55 articles consisted of 17 case series and 38 case reports with level III/IV and level V of evidence, respectively. Of the 155 identified pediatric patients, the rate of major complications was 13.5% and minor complications was 24.5%. The most common complication was mild growth distortion (n = 7) at the recipient site. Complications at the donor site were less common. During follow-up, 29 patients (18.7%) underwent or awaited surgical revision, and 43 patients (27.7%) underwent or awaited dental rehabilitation.

CONCLUSIONS

Our study suggests that the free fibular flap for pediatric maxillofacial reconstruction is safe and reliable. Additionally, surgical revision to correct the functional impairments resulting from primary reconstruction using the free fibular flap is relatively common.

Mandibular Fractures: Diagnosis and Management

Accurate evaluation, diagnosis, and management of mandibular fractures is essential to effectively restore an individual's facial esthetics and function. Understanding of surgical anatomy, fracture fixation principles, and the nuances of specific fractures with respect to various patient populations can aid in adequately avoiding complications such as malocclusion, non-union, paresthesia, and revision procedures. This article reviews comprehensive mandibular fracture assessment, mandibular surgical anatomy, fracture fixation principles, management considerations, and commonly encountered complications. In addition, this article reviews emerging literature examining 3-dimensional printing and intraoperative imaging.
