![]() ![]() Plates were designed and combined with the mandible and analyzed under a 500-N load. Three-dimensional models were generated using patient-specific geometry for the mandible obtained from a computerized tomographic image of a healthy living man. ![]() The modeled techniques were 1) 1 straight plate, 2) 2 parallel straight plates, 3) 2 angulated straight plates, 4) 1 trapezoidal plate, and 5) 1 square plate. Five titanium plating techniques for fixation of condylar fracture were analyzed using the finite element method. The aim of this study was to compare the performances of 5 plating techniques for fixation of unilateral mandibular subcondylar fracture. Endoscopic subcondylar fracture repair was efficacious at functional, aesthetic, and radiographic restoration of the mandible.Īssessment of the Biomechanical Performance of 5 Plating Techniques in Fixation of Mandibular Subcondylar Fracture Using Finite Element Analysis.ĭarwich, Mhd Ayham Albogha, Mhd Hassan Abdelmajeed, Adnan Darwich, Khaldoun Late radiographs showed fracture union without remodeling of the condylar head. Anatomic fracture reduction with rigid plate fixation was confirmed on early postsurgical radiographs. Patients were pleased with the aesthetic restoration of their chin projection,jaw line, and the symmetric midline movement of the chin point onjaw opening. Clinical jaw motion was found to progressively increase with a mean interincisal jaw opening of 43 mm achieved after the eighth postoperative week. Restoration of mandibular function was achieved without postoperative maxillomandibular fixation. To determine the effectiveness of this new technique, we longitudinally studied functional, aesthetic, and radiographic parameters following endoscopic repair of 22 subcondylar fractures in 20 patients. Lee, C Mueller, R V Lee, K Mathes, S JĪn endoscopic method of mandibular subcondylar fracture repair has been described recently. The association between theĮndoscopic subcondylar fracture repair: functional, aesthetic, and radiographic outcomes. The maximum operation duration was 165 minutes, and the average duration of ORIF was 97 minutes. All patients achieved satisfactory ranges of temporomandibular joint movement with an interincisal distance of more than 40 mm without deviation and stable individual centric occlusion. The subcondylar fracture was on the left side in 6 patients and on the right in 5. Eleven patients with subcondylar fractures of the mandible were treated with a transoral approach using an angulated screwdriver. Nine patients had a symphyseal or parasymphyseal fracture, and 2 patients had isolated subcondylar fractures of the mandible. There were 10 male patients and 1 female patient aged 21 to 72 years (mean, 38 years). Eleven patients with subcondylar fractures of the mandible were treated through a transoral approach using an angulated screwdriver. ![]() A study was conducted between March 2011 and October 2012. Therefore, this clinical study evaluated the clinical results of ORIF for mandibular subcondylar fractures through a transoral approach using an angulated screwdriver system without endoscopic assistance. However, extraoral approaches have a high rate of surgical complications such as salivary fistula formation, visible scarring, and facial nerve injury, compared with intraoral approaches. The retromandibular, submandibular, and perilobular approaches are commonly performed in the treatment of displaced condylar or subcondylar fractures and that the functional results of these treatments are good. Most surgeons prefer to treat subcondylar fractures by extraoral approaches rather than intraoral approaches because extraoral approaches provide good visualization of the operative field. Although closed reduction is the most useful method, it can be difficult to achieve anatomical reduction with this technique compared with open reduction and internal fixation (ORIF). The management of subcondylar mandibular fractures has been a matter of controversy.
