The treatment of mandibular condyle fractures has been the subject of considerable discussion, especially whether open or closed treatment should be used. There is a need for practical,evidence-based guidelines, and both objective and subjective parameters should be measured. To date, fewstudies have considered clinically relevant subjective parameters. This study was performed to evaluate the outcomes of the treatment of condylar fractures using the Mandibular Function Impairment Questionnaire (MFIQ) and the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and to compare the outcomes of open and the closed treatment...

Nuclear medicine studies evaluate physiology on a molecular level providing earlier detection of lesions before morphologic change is evident. 99m Tc-MDP and 18 F-fluoride bone scans detect osteomyelitis earlier than radiographs and computed tomography (CT); aid in diagnosis of temporomandibular joint disorder; and evaluate activity of condylar hyperplasia, extent of Paget disease, and viability of bone grafts. 18 F-FDG PET/CT distinguish between soft tissue and bone infections and diagnose osteomyelitis complicated by fracture or surgery...

Despite condylar fractures representing one of the most common sites of mandibular fractures, intracranial condylar dislocation is a rare event. In this article, the authors report 2 patients. The first patient is a young female with signs and symptoms as commonly reported in the literature. The second patient reports the consequences of a delayed diagnosis of intracranial condylar fracture dislocation. Both patients underwent surgical treatment. These patients are discussed with a review of the literature, noting biomechanics and mechanism of injury, diagnostic methods, and the treatment for these fractures...

The use of virtual surgical planning and computer-aided design/computer-aided manufacturing has previously been reported to enhance the planning for the reconstruction of mandibular continuity defects and to reduce surgical time. Reported is a case of a large keratocystic odontogenic tumor (KOT) affecting right hemimandible including the condylar neck. This case was initially reconstructed with a condyle-bearing reconstruction plate, but because of fatigue fracture 15 years later, a new reconstruction with a custom-made total joint temporomandibular prosthesis was performed...

Surgical treatment of AO/OTA type 33-C fractures is a therapeutic challenge despite advances in surgical instruments and techniques. We introduce a novel surgical technique named transient retrograde interfragmentary compression (TRIC) to help intraarticular fragment reduction in AO/OTA type 33-C fracture. We inserted a partial threaded 7.0-cannulated screw with a washer along the transepicondylar axis from the medial femoral epicondyle during the articular block reduction process of AO/OTA type 33-C fractures to strengthen the compressive force between the condylar fragments and to enhance the handling of the articular block fragment in the alignmental correction stage...

In 2009, a pit burial dated to the Bronze Age was excavated in Monte do Gato de Cima 3 (Portugal). The purpose of this paper is to describe the pathological absence of the left mandibular condyle noted in an adult male skeleton and to discuss possible diagnoses, including subcondylar fracture, cystic defect, congenital absence, condylar aplasia and mandibular condylysis. The most likely explanation for the pathological alteration is subcondylar fracture with non-union. Although the occurrence of non-union and slight osteoarthritic alterations in the left glenoid fossa were evident, this mandible was likely functional, as can be inferred from dental wear and muscle attachment sites...

Condylar fractures account for one third of all mandibular fractures. Despite being highly prevalent, treatment of these fractures remains controversial because of the sequelae of inadequate closed reduction and the risks associated with open repair. Multiple studies attempt to compare closed reduction with maxillomandibular fixation (MMF), open reduction with internal fixation, and endoscopic reduction with internal fixation. In our practice, we favor closed reduction with MMF except in cases of significantly displaced subcondylar fractures...

Continuing controversy exists for the choice of implant for treating A3 trochanteric hip fractures so we undertook a systematic review of randomised controlled trials from the year 2000 onwards that have compared an intramedullary nail with an extramedullary fixation implant for the treatment of these fractures. Data on the occurrence of any fracture healing complications was extracted and the results combined to calculate Peto odd ratio. Nine studies involving 370 fractures were identified. Three studies involving 105 fractures compared an intramedullary nail with a static fixation (condylar, blade or locking plate)...

This study aims to identify and distinguish various factors that may influence the clinical symptoms (limited mouth opening and malocclusion) in patients with maxillofacial fractures. From January 2000 to December 2009, 963 patients with maxillofacial fractures were enrolled in this statistical study to aid in evaluating the association between various risk factors and clinical symptoms. Patients with fractured posterior mandibles tended to experience serious limitation in mouth opening. Patients who sustained coronoid fractures have the highest risk of serious limitation in mouth opening (OR = 9...

The great incidence and controversies related to the diagnosis, treatment, surgical accesses, and type of osteosynthesis materials confer an outstanding role to condylar fractures among facial fractures. Plate configurations, with diverse formats and sizes, may be used to surgically resolve condylar fractures. With the purpose of improving the advantages and minimizing the disadvantages of fixation techniques, the neck screw was developed aiming at the needed stabilization to render a correct fixation through a system of dynamic compression...

OBJECTIVE: The current classification of mandibular condyle fractures as basal, low neck, and high neck as reported by Loukota et al. (Br J Oral Maxillofac Surg 43:72-73, 2005) and Neff et al. (Craniomaxillofac Trauma Reconstr 7:S44-S58, 2014) has a weakness. Nearly no high-neck fractures are reported (they are typically classified as type C head fractures) contrary to basal condylar fractures, which are overestimated (nearly all low-neck fractures are classified as basal). The aim of this study is to present a modified AO/SORG classification of mandibular condyle fractures...

Pseudoaneurysms are an uncommon complication of mandibular condylar-subcondylar fractures; however, if present, their recognition and management is mandatory to avoid life-threatening situations. The authors report a case of internal maxillary artery pseudoaneurysm rupture that occurred after an open reduction and internal fixation of a mandibular subcondylar fracture, along with a review of the literature.
