Context:Three-dimensional (3D) locking plates has been designed with the hypothesis that this will overcome the disadvantages of both the systems and also advantages of both systems will be combined for the management of mandibular fractures.Aims:The purpose of this study was to evaluate the efficacy of 2-mm 3D locking miniplate in the management of anterior mandibular fracture and to compare it with Champy's miniplate.Settings and Design:A prospective, randomized, clinical trial was carried out in thirty patients who were divided equally in two groups.Subjects and Methods:Group I and Group II patients were treated with 2-mm 3D locking plates and 2-mm standard miniplates, respectively. They were evaluated according to the outcomes of the study, that is, working time, wound dehiscence, infection, segmental mobility, postoperative occlusion, need for postoperative intermaxillary fixation (IMF), and radiological evaluation of reduction and fixation.Statistical Analysis Used:Student's t-test and Mann–Whitney test were used to compare the two systems. The data were analyzed using Statistical Package for the Social Science version 14.0. The P value was taken as significant when <0.05 (confidence interval of 95% was taken).Results:The mean duration of procedure for Group I was found to be 49.33 min, whereas for Group II was 59.67 min. There was significantly greater pain on day 1 and at 1 week in Group II patients. 6.7% (n = 1) of both groups showed incidence of infection. Postoperative stability was adequate in most cases except in one patient (n = 1) of 3D locking system, which was revealed as postoperative occlusal disharmony, unsatisfactory radiological reduction of the fracture fragments, and the segmental mobility. There was no incidence of wound dehiscence, tooth damage, and nerve damage in either group.Conclusions:The result of the study can conclude that there is no major difference between both systems in terms of treatment outcome.

Fracture of the zygomatic arch is usually treated using blind methods. As the fracture lines cannot be visualised directly in closed reduction, digital exploration and crepitus noise or conventional radiographic imaging are used clinically as a guide to reposition the fragments. Successful closed reductions are often difficult to evaluate clinically because of the great amount of swelling that often accompanies these fractures. Postoperative radiographs are often the only way to assess the adequacy of the reduction. This article describes a technique that uses the C-Arm to quickly and accurately evaluate the reduction intraoperatively so that appropriate corrections can be made. A case report of a patient who suffered a w-shaped depressed fracture of the left zygomatic arch and zygomatico-maxillary complex fracture is presented.

Review of literature revealed atleast 30 cases of post herpes zoster osteonecrosis of maxilla or mandible. To our knowledge this is a first reported case of Ramsay-Hunt syndrome with post herpetic neuralgia and post herpes zoster osteonecrosis of edentulous maxilla and mandible. We have briefly reviewed the pathophysiology and management of post herpes zoster osteonecrosis and post herpetic neuralgia.
