Reciprocal Clicking

Background: Patients referred for orthodontic treatment often present symptoms of temporomandibular joints’ disorders (TMD), predominantly clicking. The objective was to analyze the morphology of the temporomandibular joints in cone-beam computed tomography (CBCT) images based on the presence of reciprocal clicking before orthodontic treatment. Methods: 105 participants took part in the study. 210 temporomandibular joints (TMJs) were allocated into one of two groups regarding the presence of reciprocal clicking. Morphology of condyle’s head, glenoid fossa, and articular eminence as well as condylar head position in the glenoid fossa and osteoarthritic changes in the area of the condylar head were examined for each TMJ in the CBCT images. Statistical analysis was performed with STATISTICA version 12.0. The following tests were performed: U-Mann Whitney, Kruskal-Wallis, t-Student, and chi-square. The statistical significance level was p = 0.05 for all the measurements included. Results: Significantly smaller condylar A-P dimension (p = 0.040) characterized temporomandibular joints with reciprocal clicking. Condyles were substantially more often positioned posteriorly (p = 0.043) and were significantly more often accompanied by subcortical cysts and pathologic osteoarthritic bone changes (p < 0.001). Conclusions: The early stages of internal derangements stay with alterations in morphology and position of TMJs as well as with the presence of osteoarthritic changes.

Abstract Open treatment of condylar base and neck fractures is widely recommended, whereas treatment of condylar head fractures is still controversial and just is removal of osteosynthesis material. In this study, bone resorption and remodelling after open treatment of condylar head fractures were three-dimensionally (3D) assessed and correlated with clinical parameters in a medium follow-up. Of 18 patients with 25 condylar head fractures who underwent open reduction and internal fixation, clinical data and cone beam computed tomography (CBCT) datasets were analysed. Condylar processes were segmented in the postoperative and follow-up CBCT scans. Volumetric and linear changes were measured using a sophisticated 3D-algorithm. In the course after surgery, patients function and pain improved significantly. Low rates of postoperative complications were observed. All 3D measurements showed no significant bone resorption during the follow-up period. Open reduction of condylar head fractures leads to good patients outcomes and low rates of long-term complications. This study underlines the feasibility and importance of open treatment of condylar head fractures and may help to spread its acceptance as the preferred treatment option.

 Background: Cone beam computed tomography (CBCT) provides precise imaging of temporomandibular joint anatomy without superimposition and distortion. CBCT is relatively a new imaging modality and used commonly in dental practice.Objective: The aim of this study is to present detailed imaging of   emporomandibular joint in case of condyle fracture using CBCT for its use in diagnosis, surgical planning and evaluation of treatment.Method: In our study, we evaluated 3D - CBCT (three dimensional Cone beam computed tomography) examinations of 18 patients with mandibular condyle fractures. All of the fractures in our cases were overlooked on CBCT, thus providing axial, coronal and para-sagittal imaging of condylar head including 3D dimensional volumetric images of the condyle and surrounding structures.Result: Out of 18 condylar fracture patient’s CBCT, 8 radiographs showed condylar head (intracapsular) fracture, 2 condylar neck, 8 subcondylar fracture. 13 condylar fractures were unilateral and 5 were bilateral fracture. 9 of the condylar fractures were not associated with the mandible fracture. Out of the 9 associated condylar fractures; 3 were associated with symphysis fracture, 4 associated with parasymphysis fracture, 1 associated with body fracture and remaining 1 associated with mandibular angle fracture. 6 of the condylar fracture showed no signs of displacement of the fractured part and among 12 displaced condylar fracture parts 8 medially and 4 laterally displaced recorded in CBCT. All of the patients were given treatment on the basis of CBCT diagnosis and the results obtained from it was clinical satisfactory without complaints.Conclusion: We concluded that CBCT is the latest sophisticated technology which provides clear image of condylar head without superimposition of other structures, presented supplementary information for a more effective diagnosis and management of mandibular condyle fractures. Health Renaissance 2015;13 (3): 73-81

In this article, we evaluate the effectiveness of Cone Beam Computed Tomography, through a case study, in assessing the complication of intracranial bleeding during an endovascular treatment of brain arteriovenous malformation when compared to Multislice-Detector Computed Tomography performed immediately after the procedure. The image quality of Cone Beam Computed Tomography has enough diagnostic value in differentiating between haemorrhage, embolic materials and the arteriovenous malformation nidus to facilitate physicians to decide for further management of the patient.
