Abstract
Background: The fractures of the comminuted type have a prevalence of 30 to 50% when related to the ones affecting the mandibular bone. They are characterized by the presence of multiple bone fragments involving several lines of fracture, resulting in small fragments within the same area. Usually resulting from high-energy trauma, they cause large displacements, tooth loss, as well as associated lesions in soft tissues. Cases Reports : This study aimed to report two cases addressing the simplification method in the reduction of comminuted fractures treated by the method of open reduction and functionally stable fixation, which emphasized the importance of establishing a sequence of reduction maneuvers and application of osteosynthesis for a functional, occlusal and aesthetic result of the lower facial third. Conclusion: The simplification of mandibular comminuted fractures proves to be an excellent ally when one intends to reduce difficulties of reduction of the fracture and the dental occlusion on the transoperative, as well as to facilitate the application of 2.4 reconstruction plates.
Highlights
The fractures of the comminuted type have a prevalence of 30 to 50% when related to the ones affecting the mandibular bone
There has been a significant increase in Craniomaxillofacial trauma and the mandible fracture occupies the second place among the fractures of facial bones, affecting around 20% to 50% [1, 2]
Bone that requires a relatively strong trauma to have it fractured and may be a result of practicing sports, injury caused by firearm or a weapon, physical assault, tooth extraction, workplace accidents, metabolic diseases and tumors [4, 5, 6, 7, 8]
Summary
The fractures of the comminuted type have a prevalence of 30 to 50% when related to the ones affecting the mandibular bone. There has been a significant increase in Craniomaxillofacial trauma and the mandible fracture occupies the second place among the fractures of facial bones, affecting around 20% to 50% [1, 2]. This is because, due to their anatomy, topography, and projection in the lower facial third, they are often injured. ISSN: 1755-7682 J bone that requires a relatively strong trauma to have it fractured and may be a result of practicing sports, injury caused by firearm or a weapon, physical assault, tooth extraction, workplace accidents, metabolic diseases and tumors [4, 5, 6, 7, 8]. According to the anatomical region, the distribution of the main fractured sites have been reported as 16% to 33% involving the body; 23.1% to 27.3%, the angle; 19.5 to 29.3%, the condyle; 8.4% to 22%, the symphysis; 16% to 33% parasymphysis; 1.7% to 2.4%, the ramus; 0.2% to 4.8%, the coronoid process and 1.4% to 3.1% in the alveolar process [11, 12, 13]
