Fracture, Parasymphysis, Mandibular


Mandibular fractures are among the most common injuries to the facial skeleton. Mandibular parasymphysis fractures lead to the loss of occlusion with step deformity formation. Treatment of mandibular fractures aims to restore occlusion and function and facilitate direct bone healing by adequate reduction and immobilization on the fractured site. We report a mandibular parasymphysis fracture of 17 years old male patient due to the road traffic accidents. Patient reported severe jaw pain during movement and abundant intraoral bleeding was observed. A clinically computed tomography scan of the face with axial, coronal, and 3-D reconstruction was performed, which showed parasymphysis fracture. The following treatment done was the application Arch bar and open reduction internal fixation (ORIF) mini plate under general anesthesia. After access, mandibulomaxillary fixation was performed to ensure satisfactory occlusion after adequate fragment reduction. The fractures were properly fixed with 6 hole and 3 hole, screw 8mm for the left mandibular, and for the right mandibular used 5 hole and 3 hole, screw 8 mm. Mandibular fractures are the most common fractures of facial region and treatment options depend upon the type of fracture of mandible according to the anatomic variations.
