Purpose The endoscopic-assisted technique for the treatment of subcondylar fractures has been used successfully and its acceptance develops as more surgeons gain experience. We present the short term results of this technique in a randomized prospective clinical trial. Methods and Materials A total of 40 patients with mandibular subcondylar fracture were included in our study in two groups randomly. Patients of first group were treated by closed treatment technique and patients of second group by transoral endoscopic-assisted open reduction. All patients were followed for minimum of 12 weeks and occlusion, Mandibular Anterior Opening (MAO), mandibular deviation, and posterior ramal height were assessed. Results In the endoscopic group the MAO was significantly greater and mandibular deviation was lesser at 2nd and 4th week of follow up. Posterior ramal height showed significant increase in the endoscopic group rather than closed treatment group. Conclusion The transoral endoscopic-assisted technique is a reliable and successful technique to address subcondylar fractures. The patients who were treated by this technique showed better results in the fields of mandibular function and patient satisfaction and comfort, although it is time consuming and needs expensive instruments.

Introduction: The purpose of our study was to evaluate patients and technique and complete a review of the literature related to Zigzag genioplasty. Materials and Methods: To address the research purpose, the investigators designed and implemented a prospective clinical trial study. Seven osteotomy types (I–VII) are proposed for genioplasty that will permit one to decrease the 3-dimensions of the chin. These osteotomy designs are based on the displacement of bone fragments on the slopes of an inclined plane with a superior-medial direction. Results: All of the patients were satisfied with the esthetic results of their osteotomy. Based on presurgical and post-surgical facial analysis and clinical evaluations, no patients who received a Zigzag osteotomy suffered from permanent neurosensory deficiency, infection, hardware failure, severe pain, asymmetry, necrosis, massive hematoma, relapse, or suprahyoid muscle dysfunction. Conclusions: As a result, on the basis of our experience with 23 patients and after at least 1 year of follow-up with each one, the authors concluded that this technique is simple and easy to implement.

Background and Objectives The ideal line of osteosynthesis in mandibular angle fractures indicates that a plate might be placed either along or just below the external oblique ridge. Some authors believe that using one miniplate at this line at the mandibular angle region provides sufficient strength to stabilize the fracture but others imply a second plate is required. Such controversies exist in the use of maxillomandibular fixation (MMF). The intention of the present study was to compare efficiency and complications of using one miniplate with and without MMF in mandibular angle fractures. Methods and Materials Forty patients with facial trauma with mandibular angle fractures including displaced and unfavorable fractures were categorized into two groups of 20 persons. In all patients, one miniplate was placed on the external oblique ridge. In the first group, patients had light maxillomandibular elastic bands just after surgery but no rigid MMF. In the second group, patients had rigid MMF for 2 weeks after surgery. Patients were followed to evaluate complications and treatment efficiency. Conclusions Our study showed that use of a single miniplate in the external oblique ridge is a functionally stable treatment for all types of angle fractures (including displaced and unfavorable fractures) except comminuted and long oblique fractures, which were not included in our study. Use of postoperative MMF did not improve the results.
