In this study, the condylar region was the most common site of mandibular fracture. Our results are in agreement with the observations of other studies reporting the condyle as the most common fracture site of the mandible. In preschool children, condylar fractures accounted for the majority of cases (52%) and the incidence decreases with increasing age. The condylar process in children has high bone marrow content and the cortex is relatively thin. Therefore, this causes low resistance to low velocity trauma during fall. Overall, condylar fractures in the present study accounted for 39% of all mandibular fractures. This is comparable with the results of Almahdi and Higzi3 (29.8%), Joshi et al.8 (40.9%), Namdev et al.16 (40.3%), Owusu et al.17 (27.9%), and Shi et al.27 (55.7%). In addition, approximately half of patients (48.3%) presented with fractures at more than one site. Multiple fractures most commonly involve the parasymphyseal and condylar regions. Patients with RTA as the main etiology for mandible fractures have reported the parasymphysis and condyle to be common fracture sites9.

Haug and Foss2 concluded that mandibular angle fractures are rare in children and adolescents. Shi et al.27 reported mandibular angle fractures in only 3.5% of cases, which primarily occurred in patients with permanent dentition. In our study, the mandibular angle was the second most common fracture site and the incidence of fracture to this area increased with age. This finding is supported by the observations of Almahdi and Higzi3, Owusu et al.17, and Thorén et al.28, who also reported that mandibular angle fractures consistently increased with age. In addition, the overall incidence of fractures of the parasymphysis (18.3%) and body (15.3%) were comparable with the results of Muñante-Cárdenas et al.4 who observed similar incidences of fractures of the parasymphysis (18.7%) and body of the mandible (15.1%).
Revised from preceding variations to reflect present day exercise, this e book outlines the concepts of treating fractures of the mandible, and is meant for students and wellknown practitioners. subjects discussed encompass surgical anatomy, fractures of the condylar region, and publish-operative care.
The relative fragility of the midface skeleton makes it act as a cushion for trauma directed towards the cranium from an anterior or anterolateral direction. The facial skeleton can be designated by this famous figure, where the skull is similar to a helmet, the midface is similar to a matchbox (crumble zone) and the mandible is similar to a hockey stick (Fig. 55.3). The most common causes of facial fractures in the adult population are assaults and motor vehicle accidents [5].
Surgical management of impacted third molars is a treatment performed by dentists and its indicated for various conditions, among the indications has the prevention of mandibular fracture, but this is a factor that has been discussed and is controversial. Fractures caused by a third molar can occur, and on the other hand, the fractures after or during the management of impacted third molar are a possible complication. Surgical planning as the indication to the surgery has to be performed to avoid complications as the fracture. Thus this study aims to report a case about a mandible fracture after third molar extraction, presenting edema, pain, and restriction in mandible mobility in 01-day follow-up. A 27-year-old female was referred to the oral and maxillofacial surgery service of the Santa Casa Hospital of Araçatuba (Araçatuba, Brazil), reporting dental history of third molar removal, with immediately chief complaints. In the assessment, the patient presented edema, pain, malocclusion, and restriction in mandible mobility, and the panoramic X-ray showed a mandible fracture with displacement. The patient underwent surgery under general anesthesia to open reduction with internal fixation (ORIF) through an intraoral approach. On the follow-up, the patient showed an improvement in mouth opening and mandibular mobility without pain or infection signs. The panoramic X-Rays showed us the bone fracture healing.
The present study was conducted in six patients having fractured mandible with a total no of twelve fractures sites. All the patients were treated with locking 3D titanium miniplates..
(he mandible due to its relatively prominent position is more prone for fractures and accounts for the most common facial bone injuries. Almost, 50% of the mandibular fractures occur in the teeth bearing region.
The sites of fractures in the mandible consisted symphysis, parasymphysis, body, and angle and excluded condylar fractures, all of which were treated with open reduction and internal fixation with conventional stainless steel miniplates (2 and 2.5 mm, 4 and 6 holes plates). The patients were clinically and radiologically evaluated during preoperative, immediate postoperative, 6 weeks postoperative and during regular follow-ups.
The mandible is the area of the face with major incidence of fracture. Its prominence and position in the skeletal face predispose to frequent traumas. Some studies[5] have demonstrated that it is really common to observe teeth in the line of fractures. Others authors[6] mentioned that the presence of the teeth can be one of the determinant factor of the fracture location. 2ff7e9595c
