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 management of fractured mandibles typically involves admission and operation at the time of presentation. While this should involve only a short stay in hospital these patients are surgically stable, and so priority is often given to more urgent cases. We retrospectively evaluated the postoperative medical requirements of patients who were operated on at Fiona Stanley Hospital, Perth, Western Australia between 1 January 2015 and 31 December 2016. Patients were excluded if they had had multiple facial fractures, multiple injuries, had fractures that were comminuted or in edentulous mandibles, and those who had been in hospital for preoperative medical investigations and care...

PURPOSE: The utility of postoperative mandibulomaxillary fixation (MMF) after open reduction and internal fixation (ORIF) of mandible fractures is debated. The purpose of this study is to analyze if patients undergoing ORIF with postoperative MMF have improved outcome compared with those treated with ORIF alone. METHODS: A retrospective study was performed on patients who underwent ORIF of isolated mandibular fractures. Patients were divided into those placed in MMF postoperatively (ORIF with MMF) and those who were not (ORIF only)...

PURPOSE: The incidence of fractures of edentulous mandibles is relatively low. Knowledge about the management of these fractured edentulous mandibles relies heavily on case reports and observational studies. On the basis of the current literature, we compiled a treatment protocol for fractures of the edentulous mandible and hypothesized that this protocol would result in fewer complications. PATIENTS AND METHODS: We conducted a retrospective cohort study of edentulous patients with mandibular fractures...

Lingual nerve injury is a rare complication of general anesthesia. The causes of lingual nerve injury following general anesthesia are multifactorial; possible mechanisms may include difficult laryngoscopy, prolonged anterior mandibular displacement, improper placement of the oropharyngeal airway, macroglossia and tongue compression. In this report, we have described a case of bilateral lingual nerve injury that was associated with orotracheal intubation for open reduction and internal fixation of the left distal radius fracture in a 61-year-old woman...

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...

Aim: The aim of the study was to evaluate the capacity to resist fracture in different core buildup materials with porcelain fused to metal (PFM) crown. Materials and methods: Totally, 45 mandibular single rooted first premolars were collected, which were sound along with similar shape and size. The teeth were sectioned at 15 mm above the root apex sparing the sound tooth structure. The teeth were endodontically treated with the crown-down technique using nickel-titanium (NiTi) instrumentation. The specimens were randomized into three groups as per the core materials used and were labeled accordingly...

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...

Background: The difficulties in surgical treatment of pilon fractures of the finger include fragment reconstitution and posthealing stiffness. In adults, external fixation with traction and early active range of motion (AROM)/passive range of motion (PROM) during healing is considered necessary for avoiding joint stiffness and attaining realignment. The authors present a unique approach to pediatric pilon fractures that uses open reduction and multivector external fixation with delayed AROM/PROM...

BACKGROUND: Despite substantial displacements, fractures of the mandibular condyle rarely lead to necrosis. This illustrates the negligible role of the inferior alveolar artery in intraosseous supply to the condyle, and led to this systematization of its arterial vascularization. METHODS: Forty-two temporomandibular joints from nonembalmed cadaveric specimens were studied following injection of latex (n = 32) or India ink (n = 10). RESULTS: The intraosseous branches of the inferior alveolar artery that lead to the condyle were inconstant and often rudimentary...
