Mandibular Fracture Patterns in a Rural Setup: A 7-Year Retrospective Study

Comparison of Pediatric and Adult Mandibular Fractures: Identifying Differences in Presentation and Management Using a National Trauma Database

BACKGROUND

Facial fractures in children are less common than in adults but can lead to significant long-term complications, including growth abnormalities and functional issues. Mandibular fractures are the most common facial fractures in both age groups, yet there is no consensus on optimal management strategies. This study investigates the epidemiology, presentation, treatment, and outcomes of mandibular fractures in pediatric versus adult populations.

METHODS

The authors conducted a retrospective, population-based study using 2016 to 2019 data from the National Trauma Data Bank. Patients with mandibular fractures were categorized into pediatric (below 18 y) and adult (18 y or above) groups. The authors analyzed demographics, fracture mechanism, treatment modality, hospital outcome, and complication data.

RESULTS

Of the 42,866 patients with operative mandibular fractures, 3968 were pediatric (mean age: 13.3 y), and 38,898 were adult (mean age: 36.2 y). The primary fracture etiology for both groups was being struck, followed by motor vehicle incidents and falls. Pediatric patients were more frequently treated at level I trauma centers, had shorter times for surgical intervention, and were more frequently transferred to other facilities compared to adults. Antibiotic use was similar between groups, and hospital complications were infrequent, with low rates of infection and unplanned return to the operating room.

CONCLUSIONS

Mandibular fractures in children, though less common than in adults, exhibit unique epidemiological and management characteristics. Children were more frequently transferred for care and received surgical intervention sooner than adults. Antibiotic use and complication rates were low and similar across both groups. Further research is needed to establish specific treatment guidelines for pediatric mandibular fractures.

Postoperative Complications following Open Reduction and Rigid Internal Fixation of Mandibular Condylar Fracture Using the High Perimandibular Approach

The high perimandibular approach is a feasible surgical technique for treating mandibular condylar fractures with open reduction and internal fixation, followed by fewer complications. Temporary trismus is the only postoperative complication that may occur. This study evaluated postoperative complications following open reduction and rigid internal fixation (OR-IF) of mandibular condylar fractures using the high perimandibular approach. Twenty consecutive patients undergoing OR-IF were included in this study. They included 11 male and 9 female patients, of an average age of 58.5 years, all of whom responded to a follow-up call at least 12 months after the surgery. All patients were evaluated for range of mouth opening, postoperative complications, and radiological findings. A statistical analysis of the relationship between range of mouth opening and related clinical parameters at 6 months postoperative evaluation was conducted. The fracture of the condylar neck was associated with a limited range of mouth opening and longer operation time. However, longer operation time was not associated with a limited range of mouth opening. The high perimandibular approach with OR-IF in mandibular condylar fractures is a feasible and safe technique; however, prolonged surgery and mandibular condylar neck fractures could affect the postoperative range of mouth opening.

Comparative Evaluation of Conventional Miniplates, Three-Dimensional Miniplates and Lag Screws for Internal Fixation of Parasymphysis Fracture of Mandible-A Double-Blind Randomized Clinical Study

Purpose

The aim of this study is to clinically and radiographically evaluate the stability of parasymphysis fracture managed with lag screws, miniplates and 3D miniplates.

Materials and Method

Ninety- eight patients diagnosed with parasymphysis fracture were treated using lag screws in group 1, two 4-hole miniplates in group 2 and 3D miniplates in group 3. Intraoperative stability and duration of fixation was assessed. Postoperative clinical evaluation was done at 1 week, 1 month, 3rd month, 6th month and 1 year for complications and oral function. Radiological evaluation was done at 3rd and 6th month. Only 92 patients were considered for statistical analysis since 6 patients were lost during follow-up.

Results

Road traffic accident (65.3%) was the primary cause of mandibular fractures. Postoperative pain score showed a statistically significant difference after 1 week and 1 month duration (P value < 0.001). ANOVA test showed VAS was significantly higher at pre-op followed by 1st day and 1 week, but no significant difference after 3 months in all groups. Radiographic analysis did not show significant difference in approximation of fracture segment among 3 groups after 6 months (P-value = 0.117). Chewing efficiency at 6 months and occlusion by surgeon evaluation at 3 months showed a significant difference (P value < 0.001).

Conclusion

Lag screw fixation was technique-sensitive, relatively inexpensive and was less time consuming method when compared to miniplates and 3D plates. Lag screws and 3D plates are superior in reducing the incidence of complications and better in oblique or sagitally displaced mandibular fractures.
