PURPOSE: To investigate the facial symmetry of rats submitted to experimental mandibular condyle fracture and with protein undernutrition (8% of protein) by means of cephalometric measurements. METHODS: Forty-five adult Wistar rats were distributed in three groups: fracture group, submitted to condylar fracture with no changes in diet; undernourished fracture group, submitted to hypoproteic diet and condylar fracture; undernourished group, kept until the end of experiment, without condylar fracture. Displaced fractures of the right condyle were induced under general anesthesia. The specimens were submitted to axial radiographic incidence, and cephalometric mensurations were made using a computer system. The values obtained were subjected to statistical analyses among the groups and between the sides in each group. RESULTS: There was significative decrease of the values of serum proteins and albumin in the undernourished fracture group. There was deviation of the median line of the mandible relative to the median line of the maxilla, significative to undernutrition fracture group, as well as asymmetry of the maxilla and mandible, in special in the final period of experiment. CONCLUSION: The mandibular condyle fracture in rats with proteic undernutrition induced an asymmetry of the mandible, also leading to consequences in the maxilla.

Rapid Deceleration

Fractures of mandibular condyle may be overlooked because attention is often focused on readily apparent soft tissue injury such as lacerations and abrasions. Clinical and radiographic signs are often subtle, but the injuries caused by rapid deceleration and listed in Table 2 will serve to alert the pediatrician to the possibility of such fractures. All children in these circumstances should be carefully examined for dental occlusion and the preauricular area palpated to help formulate a clinical diagnosis. Additional evidence is gained from the finding of deviation or limitation of the jaw upon opening or edema in the preauricular area. If any of these yield abnormal findings, a good quality series of mandibular radiographs will be needed to confirm the diagnosis. Overlooking a condylar fracture may commit a child to unsightly facial asymmetry, marked malocclusion, or ankylosis requiring invasive surgery for correction. Consultation with an oral and maxillofacial surgeon or other interested specialist should be sought while the patient is still in the emergency room.

Background: In the literature no information about plates for the high-neck mandibular condylar osteosynthesis could be found despite that 30 plate designs have been published. The main course consider the basal condylar or diacapitular fractures. The aim of the study was to test mechanically all available designs (only 4 of 30 was proper) on polyurethane mandibles using an individually designed clamping system. Methods: Forces required for a 1 mm displacement of fixed fracture fragments and incidents of screw loosening were recorded. Results: It has occured that dedicated plates for fixation are much weaker than set of two straight plates (p < 0.0001). General observation is the bigger plate and more screws, the better rigid stable osteosynthesis of mandibular condyle, however, there are limitations in plates design for high-neck fractures resulted in restricted operation field. Conclusion: Double straight plates occured to be the best mechanical fixation for high-neck fractures of the mandibular condyle. Maybe other existing plates could be used but only after prebending or that fracture required novel dedicated plates design.

Trauma to the jaw can lead to fracture of the mandibular condyle. Prevalence in children is low and treatment should focus on possible long-term effects on facial bone and soft tissue growth. Trauma can result in dysfunction, facial asymmetry, mandibular retraction, dysfunction and stiffness of the temporomandibular joint. Clinical examination and imaging tests are essential to obtain an accurate diagnosis and an effective treatment to avoid possible complications. Treatment can be surgical or non-surgical, but non-surgical treatment is the method of choice in most cases. The aim of this study is to report a case of mandibular condylar fracture in a pediatric patient who underwent conservative and functional care who, with adequate monitoring by the Maxillofacial Surgery and Traumatology team and family, showed complete remodeling of the fractured bone and total recovery of the dental occlusion. Treatment in pediatric patients through conservative management allows an adequate range of mandibular movement and remodeling at the fracture site, but patient and family adherence to treatment is very important to obtain good results.

As fraturas mandibulares são o segundo tipo de fraturas mais comum que acomete a face, e elas podem ter um impacto negativo na estética e anatomia facial, bem como causar problema em atividades cotidianas como falar e mastigar. Este artigo tem por objetivo relatar o caso clínico de um paciente vítima de agressão física, que apresentou uma fratura unilateral de côndilo associada à fratura oblíqua de sínfise. Paciente do gênero masculino, 32 anos, leucoderma, através das radiografias PA de mandíbula e Towne foram constatadas fratura da região de sínfise mandibular e côndilo do lado esquerdo. A escolha para o tratamento desta fratura, foi o tratamento cirúrgico com fixação interna da fratura condilar com sistema 2.0mm. Após sete dias foi iniciada a fisioterapia com espátulas de madeira para o restabelecimento de adequada abertura bucal, apresentando ao final uma recuperação satisfatória, sem intercorrências. O uso de placas e parafusos para o tratamento cirúrgico de fraturas de côndilo mandibular e sínfise se mostrou eficaz, resultando no sucesso cirúrgico com um pós-operatório sem complicações e no reestabelecimento funcional e da oclusão.

Condyle Fracture

The most stable pattern of internal fixation for mandibular condyle fractures is an area of ongoing discussion. This study investigates the stability of three patterns of plate fixation using readily available, commercially pure titanium implants. Finite element models of a simulated mandibular condyle fracture were constructed. The completed models were heterogeneous in bone material properties, contained approximately 1.2 million elements and incorporated simulated jaw adducting musculature. Models were run assuming linear elasticity and isotropic material properties for bone. No human subjects were involved in this investigation. The stability of the simulated condylar fracture reduced with the different implant configurations, and the von Mises stresses of a 1.5-mm X-shaped plate, a 1.5-mm rectangular plate, and a 1.5-mm square plate (all Synthes (Synthes GmbH, Zuchwil, Switzerland) were compared. The 1.5-mm X plate was the most stable of the three 1.5-mm profile plate configurations examined and had comparable mechanical performance to a single 2.0-mm straight four-hole plate. This study does not support the use of rectangular or square plate patterns in the open reduction and internal fixation of mandibular condyle fractures. It does provide some support for the use of a 1.5-mm X plate to reduce condylar fractures in selected clinical cases.

Condylar Fractures

Background. Condylar fractures are commonly associated with symphysis/parasymphysis fractures. Condylar fractures have been attributed to direct and indirect traumatic forces, the direction and magnitude of the forces, and the condylar anatomy. The chief aim of this study was to determine the association between the newly defined mandibular chin angle and the occurrence of condylar fractures. Materials and Methods. A retrospective study was conducted to analyze two-dimensional computed tomography (2D CT) scans of patients with a history of chin trauma. The outcome was a symphysis/parasymphysis fracture with or without fracture of the mandibular condyle. The Mediff InstaRISPACS web-based platform was used to measure the chin angle. The cerebral aqueduct of Sylvius in the corresponding 2D CT midsagittal image was the standard reference plane to measure the chin angle. The SPSS Version 20 (IBM Corp, Armonk, NY) was used for data analysis. Results. The sample size included 120 2D CT scans of patients with symphysis/parasymphysis fractures (60 associated with condylar fractures and 60 without condylar fractures). The mean chin angle in the group without condylar fracture was 133.35 ± 3.87°, which was approximately 15° lesser than in the condylar fracture group (mean, 148.56 ± 5.49°), and these findings were statistically significant P < 0.05 . Conclusion. Individuals with a high chin angle are potentially at a higher risk of sustaining associated condylar fractures.
