Treatment of Mandibular Angle Fractures with Single Three-Dimensional Locking Miniplates without Maxillomandibular Fixation: How Much Fixation Is Required?

The aim of this simple nonrandomized and observational study was to evaluate the efficacy of single three-dimensional (3D) plate for the treatment of mandibular angle fractures without maxillomandibular fixation. A total of 30 patients with noncomminuted fractures of mandibular angle requiring open reduction and internal fixation were included in the study. All the patients were treated by open reduction and internal fixation using single 3D titanium locking miniplate placed with the help of transbuccal trocar or Synthes 90-degree hand piece and screw driver. 3D locking titanium miniplates used in our study was four-holed, box-shaped plate, and screws with 2 mm diameter and 8 mm length. The following clinical parameters were assessed for each patient at each follow-up visit: pain (visual analog scale: 0-5), swelling (visual analog scale: 0-5), mouth opening, infection, paresthesia, hardware failure (plate fracture), occlusal discrepancies, and mobility between fracture fragments. A significant decrease in pain level was seen during the follow-up visits. No statistically significant changes were seen in swelling, but mouth opening increased in the subsequent visits. Also better results were seen in terms of fracture stability and occlusion in the postoperative period. Two cases of infection and two cases of hardware failure were noted in sixth postoperative week. 3D plating system is an easy to use alternative to conventional miniplates to treat mandibular angle fractures that uses lesser foreign material, thus reducing the operative time and overall cost of the treatment. Better fracture stability and occlusion was also achieved using the 3D plating system.

Fractures of the mandibular condyle--Open versus closed--A treatment dilemma.

PURPOSE: The aim of this prospective randomized controlled study was to evaluate the superiority of open method of treatment of mandibular condylar fracture over closed method of treatment by comparing them. METHODS AND PATIENTS: Out of a total of 50 randomized patients fractures of the mandibular condylar process completed the study and were evaluated. All fractures were displaced, being either angulated between 10° and 45°. The follow-up examinations 1st day, 2nd day, 1st week, 2nd week, 6th week, and 6 months following treatment included clinical evaluation of functional and subjective parameters including visual analogue scale for pain and the interincisal mouth opening, malocclusion, deviation of mouth, range of motion, radiographic measurements were done. RESULTS: No significant difference was found between the two groups in the maximal interincisal opening, range of movements and TMJ pain. However statistically significant difference was seen in the anatomic reduction of condyle, shortening of ascending ramus, occlusal status and deviation on mouth opening on immediate postoperative phase. CONCLUSION: Both treatment options for condylar fractures of the mandible yielded acceptable results. However, a statistically significant difference was seen in the anatomic reduction of the condyle and there was no deviation on maximum mouth opening in patients treated with open reduction and internal fixation which suggests its superiority over closed method.
