Novel and Affordable Low-Cost Technique for Fixation of Parasymphyseal Fractures in Infants With Unerupted Dentition.

Purpose: Pediatric mandibular fractures are immensely challenging compared to adult fractures. The current update management spectrum ranges from the conservative one in the form of soft diet and regular follow-up, or less invasive surgical intervention by closed reduction and nonrigid fixation, to open reduction and internal fixation with plates and screws. In this study, we investigated the use of a straightforward fabricated mold for the parasymphyseal mandibular fracture in infants with an unerupted dentition.
Patients and Methods: This prospective study was conducted on 8 infants presenting with parasymphyseal fractures with unerupted dentitions in our specialized trauma center. In the operating room before the induction of anesthesia, the authors used a straightforward plastic airway to create a splint. The curved part was split into 2 transverse halves making 2 U-shaped curved pieces that were utilized as a mold. Intraoperatively, the U-shaped piece was placed over the mandible and stabilized with circummandibular wires. This molded airway is used to stabilize the fracture site for 2-3 weeks. The average period of follow-up was around 6 months.
Results: The average time of mandibular fixation was 17.6 ± 2.4 SD (14 to 20) days. The mean of the total operative time was 38.7 ± 3.5 SD minutes, ranging from 35 to 45 minutes. Our infants were observed in the outpatient clinic for 6 months postoperatively during the follow-up period. There were no noticeable complications nor any interference with tooth eruption or mandibular growth.
Conclusions: The results of this study suggest that this technique is straightforward to use and affordable. It does not require a long learning period. It also exhibits the advantage of reducing the cost in many developing countries.
