Clinical monitoring of mandibular distraction wounds can be successfully achieved through frequent use of ultrasonographic examinations. Standardization of ultrasonography based on CT findings will expand the reliability of ultrasound in monitoring callus maturation. An algorithm for evaluation of distraction wound healing is suggested.

Purpose: The aim of this study was to compare the clinical and radiological outcomes of treatment of mandibular subcondylar fractures using three-dimensional rhombus plates versus two miniplates techniques. Patients and Methods: A total of 20 patients having subcondylar fractures indicated for open reduction and plate fixation were recruited from Ahmed Maher Teaching Hospital and Faculty of Dentistry, Ain Shams University, and randomly divided into two equal groups. Study group was treated using three-dimensional rhombus plates, and the control group was treated using two miniplates (2.0): one parallel to posterior border of the mandible and the other parallel to sigmoid notch. The clinical and radiological outcomes of the treatment such as bone fixation stability, occlusion, mandibular movements, time of fixation, and cost of hardware were assessed and statistically analyzed. Results: There was no statistically significant difference between the two groups in all comparisons except time of fixation and cost of hardware, as three-dimensional rhombus plates were more costly and time saving. Conclusion: Three-dimensional rhombus plate has clinical and radiographic outcomes comparable to two miniplates, offering less operative time, with strong recommendation for high subcondylar fracture.

The objective of this study was to present a prospective study to investigate TMJ following open of unilateral subcondylar fracture using MRI. 30 adult male patients with recent history of unilateral mandibular subcondylar fractures were included. Three groups based on the method management of the subcondylar fracture mandibular fracture. Group 1 comprised patients who had unilateral condylar fractures treated by open reduction and internal fixation of subcondylar fracture using 3D rhombus plate (Orthomed) Group 2 patients were treated by open reduction and internal fixation of subcondylar fracture using 2 mini plates. Group 3 Control group were treated patients had a unilateral condylar fracture treated by closed reduction. Magnetic resonance imaging was performed on the patients within 10 days from the primary injury. The same clinical examination, radiographic and magnetic resonance imaging were performed six months later. The result of this study demonstrate that,there was no statistically significant differences observed between the three treatment groups for parameters like age, gender, type and side of the fracture, mechanism of injury and incidence of associated injuries, post-operative occlusion and need for IMF There was a no statistically significant difference between the MRI findings in all groups.
