[Ab] Abstract:AIM: The aim of this study was to analyze the pattern and treatment of craniomaxillofacial injuries in the northern part of Israel, within a Jewish majority and large Arab minority population. PATIENTS AND METHODS: A 5-year retrospective study evaluated patients treated for craniomaxillofacial fractures. Fracture cause, type, site, and patient demographics were evaluated. RESULTS: Patient age ranged from 1 to 94 years with an average age of 36.7 years; 52% of the victims were Jews and 48% Arabs. There was male predilection in both sectors (78.3% vs 21.7%). The main site of injury was the zygomatic bone (33.5%) followed by nasal bone, orbital, mandible, frontal sinus, and maxillary fractures. The main etiology of injuries was falls (45.4%) with significantly more falls reported by females (52.1% vs 43.2% in males). Motor vehicle accidents caused injuries more frequent in males. Arabs experienced CMF fractures at a younger age compared to Jews (27.8 and 44.8 average age, respectively). In the elderly, the trend reversed where Jews were more prone to craniomaxillofacial fractures. CONCLUSIONS: Compared to their weight in the population, the Arab sector experiences more craniomaxillofacial injuries. The Jewish elderly population tends to reside in nursing homes where they are more susceptible to accidental falls, whereas young Arab males are more exposed to motor vehicle accidents and interpersonal violence. Falls were the main cause of injuries particularly in women. This may reflect the women's fear of reporting domestic violence. We believe that increased government investments in infrastructures and education will lower the incidence of craniomaxillofacial trauma and balance the gap between both sectors and sexes.

[Ab] Abstract:BACKGROUND: The purpose of the present study was to evaluate changing pattern in characteristics of maxillofacial fractures and concomitant injuries in Western Libya During revolution and to assess the association between mechanism of injury and fracture patterns. MATERIAL AND METHODS: A retrospective review of medical records and radiographs of 187 patients treated for maxillofacial fractures from January 2010 to December 2012 was performed, there were 326 fractures in 187 patients. RESULTS: The male: female ratio was 6:1. Most fractures occurred in patients aged 11 to 40 years, and few injuries occurred in patients aged > 50 years. Most fractures occurred from motor vehicle accidents, and other most frequent causes included assault, gunshot, and fall injuries. Most maxillofacial fractures involved the mandible, zygomatic complex, or maxilla. Most mandibular fractures occurred at the parasymphysis, angle, or condyle. Associated injuries most frequently involved the head, chest, and extremities. Most patients were treated with open reduction (132 patients [71%]), and 26 patients (14%) were treated nonoperatively. There were 21 complications (11%). CONCLUSIONS: In summary, motor vehicle accidents were the most frequent cause of maxillofacial fracture in western Libya, possibly because of the lack of seat belt legislation. Interpersonal violence was a less frequent cause of maxillofacial fracture, possibly because of the religious restriction on alcohol consumption.

[Ab] Abstract:BACKGROUND: To investigate the occupational profile, educational level, marital status and deleterious habits to the health of patients with maxillofacial fractures of a population of northeastern Brazil. MATERIAL AND METHODS: A retrospective study of patients records admitted to the Division of Oral and Maxillofacial Surgery at the Walter Cantidio University Hospital (Fortaleza, Brazil) who sustained maxillofacial fractures was conducted in the period between 2006 and 2015. RESULTS: A total of 338 patients rendered 355 fractures. Males were the most affected (p <0.001), with prevalence in the third decade of life (p <0.001). There was a predominance of motorcycle accidents (p <0.001), home workers (p <0.001), low educational status (p = 0.032), and no cigarette use (p <0.001) or alcohol (p = 0.023). Fractures of the zygomatic-orbital complex were the most prevalent in the sample (p <0.001). CONCLUSION: The sociodemographic profile exerted a significant influence on the epidemiological profile of maxillofacial fractures in a Brazilian population during the study period.

[Ab] Abstract:Maxillofacial injuries can be complex and are clinically important due to their functional and cosmetic significance. Maltreated and missed fractures might cause deformity of the face; thus, accurate evaluation of the fracture provided by X-ray images is critical. In this study, we explore the application of cone-beam computed tomography (CBCT) for diagnosis of severe maxillofacial traumas. A patient with a complex fracture that affects the maxilla, mandible, wall of the maxillary sinus, zygoma, zygomatic arch and nasal bone was diagnosed using 3D reconstruction of CBCT images. This diagnostic approach provides detailed information obtained by static images and a systematic model with unique advantages for the following pre-surgical evaluation, surgical treatment and prognostic assessment of complex maxillofacial fractures.

[Ab] Abstract:Facial nerve paralysis is an unusual formidable complication that can manifest after various maxillofacial surgeries, including open reduction of facial trauma. The branches more predisposed to such injury are the zygomatic and marginal mandibular branches. Zygomaticomaxillary complex (ZMC) fractures are frequently encountered in maxillofacial trauma. The facial nerve has not been described as endangered during ZMC surgery. Paralysis of the buccal branch after ZMC repair with delayed onset has been reported only once. This report describes a patient with immediate facial nerve paralysis after open reduction and internal fixation of an isolated ZMC fracture through an intraoral approach. This is a previously unreported rare complication after ZMC fracture repair that should be discussed as a possibility when obtaining preoperative consent.

[Ab] Abstract:The zygomatico-maxillary complex functions as the principle buttress of the face and is the cornerstone to an individual’s aesthetic appearance. Its fracture not only creates cosmetic deformities owing to its position and facial contour, but can also cause disruption of ocular and mandibular functions. The aim of this study was to evaluate the quality, efficacy and impact of internal fixation of zygomatic complex fractures on functional and cosmetic outcomes. A prospective study was carried out on 100 patients who were divided according to the classification and the severity of injury. Subjective evaluation was submitted based on the patient’s perception of signs and symptoms in the preoperative and postoperative periods. Intraoperative and postoperative assessment of bone reduction quality was made according to the type of the fracture and related difficulties; also, the difference between these groups was observed as functional and esthetic outcome. To optimize the treatment of zygomatic bone fractures, a pre-designed questionnaire was used for subjective evaluation of symptoms and treatment outcome. In 70% of cases, ophthalmologic consultation was taken and was most common in type VII fractures (100% cases). Neurosensory disturbance was the most common finding (60%), followed by diplopia (56R%), pain upon mouth opening (54%) and malar depression (50%). Out of all possible 400 fracture sites in 100 patients of zygomatic complex fractures, 266 (66.5%) fractures were detected by clinical examination, in contrast to 330 (82.5%) on radiological examination, which were highest at zygomatic-maxillary buttress (93%) followed by infraorbital rim (91%) and almost equal among fronto-zygomatic site (72%) and zygomatic arch (74%). The scores from the questionnaire for annoyance were significantly higher for paraesthesia (23%) than for trismus (10%), pain (8.5%), or deformity (8.25%). Residual deformity and pain significantly influenced the total satisfaction. Conclusively, there are many treatment modalities available for zygomatic complex fractures, and the preferred methods should be selected on the basis of fracture type, fracture severity, pre-operative signs and symptoms. Regarding the requirements of fracture site exposure and actual fixation, one priority should be to minimize postoperative complications, morbidity and residual deformities.

[Ti] Title:Biocompatibility and Efficiency of Biodegradable Magnesium-Based Plates and Screws in the Facial Fracture Model of Beagles.

[La] Language:eng
[Ab] Abstract:PURPOSE: A biodegradable magnesium alloy system has been developed as a substitute for conventional plates and screws made of titanium or absorbable polymer. However, previous studies were limited to small animal experiments using screws or wires. In the present study, we preliminarily evaluated the biocompatibility and effectiveness of human standard-size biodegradable magnesium-based plates and screws in facial fractures of beagles. MATERIALS AND METHODS: Fracture lines were created bilaterally in the zygomatic arches of 6 beagles. They were fixed in situ with plates and screws made of magnesium alloy mixed with calcium and zinc (experimental group) or absorbable polymer (control group). Laboratory testing, radiologic imaging, histologic analysis, and mechanical testing were performed 4 weeks postoperatively. RESULTS: Inflammatory reactions were not significantly increased in any animal. Mechanical testing showed greater ultimate load and structural stiffness in the experimental group. In the histologic analysis, the void area and bone regeneration area were increased in the experimental, and the implant area and soft tissue area were increased in the control group. Radiologically, 3-dimensional micro-computed tomography showed no differences in the bone gap area between the 2 groups. A temporary increase in hydrogen gas around the magnesium implants regressed spontaneously and did not affect bone healing significantly. CONCLUSIONS: Magnesium-based biodegradable plates and screws showed good biocompatibility and offered considerable stability for fixating facial bone fractures in the early bone-healing process. These results show the possibilities for the future development of magnesium alloy plates and screws for craniomaxillofacial fixation in humans.

[Ab] Abstract:INTRODUCTION: Resorbable fixation system (RFS) is an alternative to titanium in open reduction and internal fixation of pediatric facial fractures. METHODS: This study retrospectively reviewed all medical records in a major metropolitan pediatric hospital in Cape Town, South Africa from September 2010 through May 2014. Inclusion criteria were children under the age of 13 with facial fractures who have undergone open reduction and internal fixation using RFS. Intraoperative and postoperative complications were reviewed. RESULTS: A total of 21 patients were included in this study. Twelve were males and 9 were females. Good dental occlusion was achieved in all patients and there were no complications intraoperatively. Three patients developed postoperative implanted-related complications: all 3 patients developed malocclusions and 1 developed an additional sterile abscess over the right zygomatic bone. For the latter, incision and drainage was performed and the problem resolved without additional operations. DISCUSSION: Resorbable fixation system is an alternative to titanium products in the setting of pediatric facial fractures without complications involving delayed union or malunion. The combination of intermaxillary fixation and RFS is not needed postoperatively for adequate fixation of mandible fractures. Resorbable fixation system is able to provide adequate internal fixation when both low-stress and high-stress craniofacial fractures occur simultaneously.

[Ab] Abstract:Sagittal fracture at the temporal root of the zygomatic arch often occurs as a part of zygomaticomaxillary fractures. The authors described the application of computer-assisted navigation in the lag screw insertion for the fixation of sagittal fracture at the temporal root of zygomatic arch. Using the presurgical planning of the computer-assisted navigation system, the trajectory of lag screw insertion was designed, and the insertion depth was calculated. In the presurgical planning, the trajectory of screw insertion was placed with an anterior inclination of 10° to 15° (mean: 12.24°), and the screw insertion depth was 9.0 to 12.0 mm (mean: 10.65 mm). In the operation, the screw insertion in the fixation of the sagittal fracture was performed under the guidance of navigation system according to the presurgical planning. The postoperative CT scan showed exact reduction and fixation of the sagittal fracture in all cases. Computer-assisted navigation is a useful tool for the lag screw insertion in the precise fixation of sagittal fracture at the temporal root of the zygomatic arch in complex zygomaticomaxillary fractures.

[La] Language:eng
[Ab] Abstract:BACKGROUND: Pneumatic spaces represent sites of minimal resistance, facilitating the spread of various pathological processes into the joint such as tumors, infection or fractures or vice versa. Considering the clinical importance of temporomandibular joint, prevalence of pneumatic spaces of the temporal bone in relation to TMJ in the roof of the TMJ fossa; articular eminence; zygomatic process and peritubal area was determined using Computed tomography. Laterality and gender wise prevalence of pneumatic spaces around the TMJ was also assessed. MATERIALS AND METHODS: A total of 100 high-resolution CT images of adult patients subjected to CT scan for the base of skull/temporal bone were utilized. Axial, reformatted coronal and sagittal images were analyzed on a DICOM viewer for the presence and distribution of pneumatic spaces of the temporal bone around TMJ in the roof of TMJ fossa, articular eminence, zygomatic process and peritubal area. RESULTS: The extent of pneumatization of the temporal bone varied considerably. The prevalence of pneumatization of the roof of the TMJ fossa was 52%, articular eminence (12%), the root of the zygomatic process (5%) and peritubal area was 56%. Higher frequency of bilateral pneumatization was seen. No statistically significant correlation was seen in gender wise distribution of pneumatization. CONCLUSION: The present study revealed higher prevalence of pneumatization of temporal bone around TMJ. The knowledge of these air spaces is helpful for the interpretation of imaging studies and to understand the spread of pathological processes into the joint.
