[Ab] Resumo:PURPOSE: CheckTomo is an independent dose calculation software for tomotherapy. Recently, Accuray (Accuray Inc., Sunnyvale, CA, USA) released an upgrade of its tomotherapy treatment device, called TomoEDGE Dynamic Jaws, which improves the quality of treatment plans by enhancing the dose delivery with the help of jaws motion. This study describes the upgrade of CheckTomo to that new feature. METHODS: To account for the varying width and off-axis shift of dynamic jaws fields, the calculation engine of CheckTomo multiplies the treatment field profile by a penumbral filter and shifts the dose calculation grid. Penumbral filters were obtained by dividing the edge field profiles by that of the corresponding nominal field. They were sampled at widths 1.0, 1.8, and 2.5 cm at isocenter in the edges of the 2.5 and 5 cm treatment field. RESULTS: The upgrade of CheckTomo was tested on 30 patient treatments planned with dynamic jaws. The gamma pass rate averaged over 10 abdomen plans was 95.9%, with tolerances of 3 mm/3%. For 10 head and neck plans, the mean pass rate was 95.9% for tolerances of 4 mm/4%. Finally, misplacement and overdosage errors were simulated. In each tested cases, the 2 mm/3% gamma pass rate fell below 95% when a 4 mm shift or 3% dose difference was applied. CONCLUSIONS: These results are equivalent to what CheckTomo achieves in static jaws cases. So, in terms of dose calculation accuracy and errors detection, the upgraded version of CheckTomo is as reliable for dynamic jaws plans as the former release was for static cases.

[Ti] Título:Modified Labial Button Technique for Maintaining Occlusion After Caudal Mandibular Fracture/Temporomandibular Joint Luxation in the Cat.

[Ab] Resumo:Maxillofacial trauma in cats often results in mandibular symphyseal separation in addition to injuries of the caudal mandible and/or temporomandibular joint (TMJ). Caudal mandibular and TMJ injuries are difficult to access and stabilize using direct fixation techniques, thus indirect fixation is commonly employed. The immediate goals of fixation include stabilization for return to normal occlusion and function with the long-term objective of bony union. Indirect fixation techniques commonly used for stabilization of caudal mandibular and temporomandibular joint fracture/luxation include maxillomandibular fixation (MMF) with acrylic composite, interarcade wiring, tape muzzles, and the bignathic encircling and retaining device (BEARD) technique. This article introduces a modification of the previously described "labial reverse suture through buttons" technique used by Koestlin et al and the "labial locking with buttons" technique by Rocha et al. In cases with minimally displaced subcondylar and pericondylar fractures without joint involvement, the labial button technique can provide sufficient stabilization for healing. Advantages of the modified labial button technique include ease of application, noninvasive nature, and use of readily available materials. The construct can remain in place for a variable of amount of time, depending on its intended purpose. It serves as an alternative to the tape muzzle, which is rarely tolerated by cats. This technique can be easily used in conjunction with other maxillomandibular repairs, such as cerclage wire fixation of mandibular symphyseal separation. The purpose of this article is to demonstrate a modified labial button technique for maintaining occlusion of feline caudal mandibular fractures/TMJ luxations in a step-by-step fashion.

[Ti] Título:A Detailed Analysis of Mandibular Angle Fractures: Epidemiology, Patterns, Treatments, and Outcomes.

[Ab] Resumo:PURPOSE: The purpose was to analyze mandibular angle fractures by examining epidemiologic trends and mechanisms of injury and to determine whether a statistically meaningful relation existed between certain treatment modalities and patient outcomes. MATERIALS AND METHODS: A retrospective chart analysis was performed, and data were limited to 1 operator. Treatment variables were methods of fixation, postoperative intermaxillary fixation (IMF), and retention versus extraction of teeth in the line of fracture. Outcomes were rates of postoperative infection, fracture healing, and overall patient comfort. Analysis was performed using the Fisher exact test, Wald test, and χ(2) test, with a P value less than .05 considered significant. RESULTS: One hundred three patients were included in this study. The mean age was 30.4 years, most patients were men, and most injuries occurred during physical altercations and on the left side of the face. The most common concomitant fracture was of the contralateral parasymphysis. A statistically meaningful relation was noted between methods of fixation and healing and overall patient comfort, with the Champy technique and reconstruction plate being associated with the highest rates of bony union and patient comfort. No statistically relevant correlation was found between methods of fixation and rates of infection. There was no statistically relevant link for extraction versus retention of healthy teeth in the line of fracture or use of IMF with patient comfort, postoperative infection, or fracture healing. CONCLUSION: Although the Champy technique and reconstruction plates were associated with better postoperative outcomes, such as patient comfort and fracture healing, these should not be used interchangeably. IMF and extraction versus retention of teeth in the line of fracture did not influence any of the outcomes.

[Ab] Resumo:The management of pediatric mandibular fractures is challenging for maxillofacial surgeons due to ongoing mandibular growth involving tooth buds. The treatment of such fractures has been a topic of much research. Generally accepted methods for the treatment of mandibular parasymphyseal or symphyseal fractures in children are conservative approaches involving the use of acrylic splints, lateral compression with an open-cap splint stabilized by circummandibular wiring, and maxillomandibular fixation with an arch bar and eyelet wiring. The aim of this technical note was to describe a straightforward approach to the treatment of pediatric mandibular fractures, in which an occlusal splint is secured to prevent trauma to the soft tissue, without the need for general anesthesia.

[Ab] Resumo:PURPOSE: Most studies on the surgery-first approach focused on skeletal relapse compared with conventional surgery. The objective of this study was to compare the stability of skeletal Class III patients with 2 different vertical facial types after mandibular setback surgery (MS) with minimal orthodontic preparation (MO). MATERIALS AND METHODS: In this retrospective study, the patients were recruited from a population that had undergone MS. Consecutive patients were selected based on the following inclusion criteria: skeletal Class III malocclusion with mandibular prognathism, MO without extraction for less than 6 months, and sagittal split ramus osteotomy. The vertical facial types of the patients were classified based on the Frankfort mandibular-plane angle (FMA). Lateral cephalograms were taken at the presurgical stage, at 1 month after surgery (T1), and at the debonding stage (T2). To evaluate surgical changes (T1 - presurgical stage) and relapse (T2 - T1), the linear, angular, and dental measurements were analyzed using a paired t test and an independent t test. RESULTS: The 26 patients were divided into 2 groups: normal-angle group (n = 14; mean FMA, 23.58°) and high-angle (HA) group (n = 12; mean FMA, 30.26°). From T1 to T2, the normal-angle and HA groups showed significant forward and counterclockwise rotation of the mandible (distance between pogonion and perpendicular line to Frankfort horizontal plane from sella, 1.71 mm and 1.51 mm, respectively; distance between menton and perpendicular line to Frankfort horizontal plane from sella, 1.91 mm and 1.60 mm, respectively; angle between articulare-menton line and Frankfort horizontal plane, -0.55° and -0.89°, respectively). The HA group showed a significant upward movement of the mandible (distance from Frankfort horizontal plane to pogonion, -1.13 mm; distance from Frankfort horizontal plane to menton, -0.78 mm). However, there was no significant difference in the skeletal-dental changes between the 2 groups from T1 to T2. CONCLUSIONS: The vertical facial types of Class III patients with similar prognathic mandible and dental patterns may not cause any differences in the relapse pattern after MS-MO.

[Ab] Resumo:In this video, we present a single piece Le Fort I osteotomy with bone graft in a patient with a unilateral cleft lip and palate. Maxillary osteotomies in the cleft patient can be challenging because of the presence of scar, palatal or alveolar fistulae, compromised teeth, and vascularization of the segments. The video demonstrates our current approach and technique. The authors particularly want to highlight aspects of the approach, such as the incision, exposure, osteotomies, mobilization, splints, and plating. The associated manuscript discusses the depicted video as well as the blood supply to the maxilla, and postoperative patient care.

[Ab] Resumo:Condylar resorption is understood as changes in shape and volume of the condylar bone, due to local, systemic, and iatrogenic factors. The occurrence of condylar resorption after orthognathic surgery can occur when the condylar repositioning in mandibular fossa is performed improperly. In addition, systemic diseases such as osteoarthritis and rheumatoid arthritis seem to influence this process. The aim of this study was to report 3 cases of patients with severe condylar alterations, submitted to orthognathic surgery for treatment of dentofacial deformities. Considerations regarding the diagnosis, surgical planning (counterclockwise rotation), surgical techniques (bilateral sagittal split osteotomy, bimaxillary osteotomies, rigid fixation, maxillomandibular fixation period), and results (short terms) are discussed.

[Ti] Título:Removal versus retention of asymptomatic third molars in mandibular angle fractures: a randomized controlled trial.

[Ab] Resumo:The treatment dilemma provided by asymptomatic third molars in mandibular angle fractures remains controversial. This prospective randomized controlled trial was undertaken to determine whether there is an advantage to extraction or retention of the third molar whilst repairing a mandibular angle fracture. Sixty-four patients were allocated randomly to the two treatment groups. All underwent open reduction and internal fixation (ORIF) with standard postoperative care. The primary outcome measure was uncomplicated fracture healing. Secondary measures were surgical duration, malocclusion, wound healing, nerve injury, and return to theatre. All patients had uncomplicated fracture healing. The incidence of nerve injury was 16% for the retention group compared with 39% for the removal group (P=0.038). The average operating time for ORIF and third molar retention cases was 58.5min and for ORIF and third molar removal cases was 66.3min (P=0.26). There was no statistically significant difference between groups for wound healing, occlusion outcomes, or return to theatre. Given the additional risk of nerve injury and the additional operating time required for removal of a third molar, in the absence of an absolute indicator for removal of the third molar, it appears justifiable to advise retaining the tooth in the line of a mandibular angle fracture.
