Influence of Method of Treatment of Mandibular Condylar Fractures on Range of Articular Path Measured by Cadiax Device. J Clin Med 2024; 13:3706. [PMID: 38999272 PMCID: PMC11242559 DOI: 10.3390/jcm13133706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 06/11/2024] [Accepted: 06/13/2024] [Indexed: 07/14/2024] Open
Abstract
Background/Objectives: The aim of this study was to evaluate the function of the treated temporomandibular joint based on the analysis of the image of the articular path using the Cadiax device depending on the choice of treatment method for unilateral condylar fracture of the mandible. Methods: Sixty patients who were treated for condylar fractures of the mandible at the Maxil-lofacial Surgery Department in Katowice were qualified for the analysis of the range of movements of the mandibular heads using the Cadiax device. From the group of patients who suffered fractures of the mandible, including condylar processes, patients were finally qualified for the measurement of the articular path of the injured and healthy joint according to strict criteria. Results: The condylar examination was performed in 20 patients who had conservative condylar fracture treatment and 40 patients who underwent various surgeries in the course of a single condylar fracture. The control group consisted of 20 patients whose mean values for the articular pathway measured for both sides were 12.73 and 12.69 and fell within the standard developed for healthy joints tested with the Cadiax device. Conclusions: We have achieved an almost ideal treatment for condylar fractures. We are also beginning to notice the need for rehabilitation of patients after this type of surgery.

Abstract
Pediatric facial fractures constitute a small portion of all facial fractures. The frequency of pediatric facial fractures by location, and mechanism of injury, changes over time associated with craniofacial growth and activity. Pediatric patients have protective anatomic features, such as increased soft tissue, excess adipose tissue, and more flexible bone. Conservative management is often sufficient. Surgical intervention can often be conservative. Follow-up monitoring is valuable for concerns of growth disruption from either the trauma itself or surgical interventions. Older teenage patients may often be treated similar to adults. Postoperative management varies by fracture type without a defined long-term follow-up course.

Abstract
This study aims to review surgical treatment in paediatric condylar fractures and describe different types of techniques performed, along with the results obtained from them. A retrospective review was conducted from records of paediatric patients (from one to 17 years old) who sustained fractures of the mandibular condyle and underwent surgical treatment from 2003 to 2023. The number of patients, age, location, and type of fracture, clinical and imaging examinations, treatment methods, intraoperative/postoperative complications, removal of osteosynthesis material, follow up and outcomes were recorded and analysed. A total of 68 patients with 79 fractures were identified. The most common fracture pattern was condylar neck fracture (61.1%). Of the 68 patients who underwent surgical treatment, one had a complication of minimal temporal paraesthesia and another patient had near-complete resorption of the condyle. A total of 55 patients (81%) reported normal dental occlusion, mouth opening (>35 mm), lateral excursions (7-8 mm), TMJ function, no pain, no deviation of the midline or the jaw, and no ankylosis. Thirteen patients (19%) developed an unsatisfactory result, nine patients (13%) had a jaw deviation on mouth opening, four patients (6%) had mandibular retrusion, and seven patients (10%) had signs of TMJ dysfunction. A total of 59 patients (87%) reported bone completely healed with no signs of bone abnormality; seven patients (10%) had shortening of the condylar neck and/or ramus. Surgical treatment can lead to good or excellent results for severely dislocated and displaced condylar fractures in children and can reduce the unsatisfactory results resulting from closed treatment.

Abstract
The management of pediatric facial fractures requires several considerations by the treating surgeon. Pediatric facial fractures occur less commonly than in adults. Among fracture patterns in children, studies have repeatedly demonstrated that mandible fractures are the most common facial fracture particularly the condyle. Most fractures in children are amenable to nonsurgical or closed treatment; however, certain indications exist for open treatment. The literature describing epidemiology, treatment trends, and long-term outcomes are limited in comparison with adult populations. The purpose of the article is to review the etiology, workup, and management of mandible fractures in children.

Abstract
Pediatric panfacial trauma is a rare occurrence with poorly understood implications for the growing child. Treatment algorithms largely mirror adult panfacial protocols with notable exceptions including augmented healing and remodeling capacities that favor nonoperative management, limited exposure to avoid disruption of osseous suture and synchondroses growth centers, and creative fracture fixation techniques in the setting of an immature craniomaxillofacial skeleton. The following article provides a review of our institutional philosophy in the management of these challenges injuries with important anatomic, epidemiologic, examination, sequencing, and postoperative considerations.

Abstract
PURPOSE In our study, the characteristics, treatment approach and long-term outcomes of condyle fractures treated in the pediatric plastic surgery and reconstruction unit in the last 10 years were evaluated. MATERIALS AND METHODS This study consisted of two retrospective and prospective sections with the participation of pediatric patients with condylar fractures who were treated in the Plastic, Reconstructive and Aesthetic Surgery clinic of a university hospital in the last 10 years. In the retrospective section, data were obtained from the electronic patient records and patient files regarding the treatment applied, as well as the characteristics of the patient and condyle fractures. In the perspective section, patients were invited to the clinic and the effectiveness of the treatment was evaluated. Statistical analyses were performed with SPSS (Statistical Package for Social Sciences) for IBM 25 package program. RESULTS It was determined that 55.8% of the pediatric patients had accompanying facial fractures, and 72.4% had unilateral condyle fractures. It was determined that 59.5% of the pediatric patients underwent intermaxillary fixation (IMF). Physical complications were seen in 6.75% in the long term after treatment. CONCLUSION Falling from height and traffic accidents, which are the most important factors in the occurrence of condyle fractures, should be eliminated by increasing parental attention and awareness. Surgical treatment should be considered in the treatment of pediatric condyle fractures, especially if there are accompanying facial and mandible bone fractures.

Abstract
Facial trauma is common in the pediatric population with most cases involving the soft tissue or dentoalveolar structures. Although facial fractures are relatively rare in children compared with adults, they are often associated with severe injury and can cause significant morbidity and disability. Fractures of the pediatric craniomaxillofacial skeleton must be managed with consideration for psychosocial, anatomical, growth and functional differences compared with the adult population. Although conservative management is more common in children, displaced fractures that will not self-correct with compensatory growth require accurate and stable reduction to prevent fixed abnormalities in form and function.

Abstract
ABSTRACT The appropriate treatment of pediatric mandibular condyle fractures is subject to much debate and concern among surgeons, with improper treatment potentially resulting in a number of adverse outcomes. Such outcomes include the disruption of mandible growth, decreased posterior facial height, facial asymmetry, and temporomandibular joint ankylosis. Several surgical and nonsurgical approaches to these fractures have been described in the literature; however, each one carries its own risk of various complications. In this study, the authors illustrate a new atraumatic approach for mild to moderately displaced subcondylar fractures, with least possible complications and unexpected outcomes. In this study, 6 patients (2 female and 4 male) with unilateral medially displaced condylar base and neck fractures, angulated between 30 and 45 degrees, were treated using a novel intraoral approach. The follow-up period varied from 12 to 18 months. All patients achieved normal occlusion and had painless functioning of the temporomandibular joint with proper mouth opening (>35 mm) without any recurrence at long term follow up. This minimally invasive approach could eliminate the possibility of major complications and be considered a safe and feasible surgical technique for certain cases of pediatric mandibular condyle fracture.

Abstract
The treatment of paediatric mandibular condylar fracture (PMCF) is typically non-operative. The purpose of this study was to determine if non-operative management of PMCF results in a new condylar process of normal morphology to regenerate after closed treatment (restitutional remodelling). The specific aim of the study was to observe restitutional remodelling (RM) in PMCF and review the literature. The investigators designed and implemented a retrospective study on paediatric patients (age<12) with unilateral or bilateral condyle fractures treated with non-operative treatment between January 2005 and July 2015. Patients with complete records and at least 1-year follow-up were included in the study. Primary outcome variable was RM and secondary outcome variables were occlusion, maximal incisal opening (MIO), displacement, infection, facial asymmetry, and signs of temporomandibular joint ankylosis (TMJA). The study evaluated 41 patients {n=57 PMCF, (m:f-35:6)} of unilateral (n=25) and bilateral (n=16) PMCF. Fractured condyles remodelled to normal morphology in all the cases at follow-up. The Wilcoxon test revealed a statistically significant difference in MIO from the preoperative value to postoperative (p=0.001). Occlusion (except 1) was satisfactory in all cases, at follow-up with no gross facial asymmetry. There was no sign of infection at the surgical site (anterior mandible). None of the patients showed signs of TMJA at follow-up. The result of the present study demonstrates that RM of condylar fracture occurs with non-operative management. Non-operative management should be the point of care in PMCF, owing to the rapid RM, bone regeneration, and satisfactory outcome. Review of the literature also supports closed treatment.

Abstract
The aim of the study was to compare the outcome and complications of open reduction and internal fixation (ORIF) with closed treatment, as well as to review the literature. This was a retrospective study on pediatric patients with mandible fracture. The primary objective was a comparison of outcomes in terms of bone healing, maximal incisal opening (MIO), and occlusion, and the secondary objective was to review complications. A total of 77 pediatric patients (age <12 years) were managed with closed treatment and 23 with ORIF. In all, 62 patients were found with a single fracture (22 patients with parasymphysis fracture and 21 with condyle fracture, followed by symphysis, angle, and body fracture) and 38 patients with more than one fracture, with symphysis and bilateral condyle fracture being the most common. Bone healing was observed in all the patients. Mean MIO was 26.9 ± 2.8 mm and 29.3 ± 1.7 mm in the closed and ORIF group, respectively, and the difference was statistically nonsignificant (p = 0.5). One patient (1.3%) had deranged occlusion, and mobility was observed in one patient (1.3%) in the closed treatment group. Infection and nerve paresthesia were not seen in any patient at follow-up. Although closed treatment is preferred, as it preserves the soft tissue and periosteum, a displaced mandible fracture especially with co-existing condylar fracture should be treated by ORIF.

Abstract
The contributing factors and the origins of precursor cells in traumatic heterotopic ossification around the temporomandibular joint (THO-TMJ), which causes obvious restriction of mouth opening and maxillofacial malformation, remain unclear. In this study, our findings demonstrated that injured chondrocytes in the condylar cartilage, but not osteoblasts in the injured subchondral bone, played definite roles in the development of THO-TMJ in mice. Injured condylar chondrocytes without articular disc reserves might secrete growth factors, such as IGF1 and TGFβ2, that stimulate precursor cells, such as endothelial cells and muscle-derived cells, to differentiate into chondrocytes or osteoblasts and induce THO-TMJ. Preserved articular discs can alleviate the pressure on the injured cartilage and inhibit the development of THO-TMJ by inhibiting the secretion of these growth factors from injured chondrocytes. However, the exact molecular relationships among trauma, the injured condylar cartilage, growth factors such as TGFβ2, and pressure need to be explored in detail in the future.

Abstract
PURPOSE Surgery with open reduction internal fixation (ORIF) for pediatric mandibular condylar fractures (MCF) is controversial. This study aims to evaluate the clinical and radiographic outcomes of the children with MCF treated surgically with ORIF. METHODS This retrospective study included 9 children diagnosed with MCF and treated surgically with ORIF. Imaging examinations were performed preoperatively and postoperatively. Patients underwent follow-up clinical observations and objective measurements for over 5 years. RESULTS All children recovered well in facial features, facial nerve functions, occlusions, joint movements, maximal incisal opening, and midline deviation postoperatively. The temporomandibular joint (TMJ) pain and click were found in 2 of 9 (22.2%) cases 1 year after surgery and disappeared 2 years later. Mandibular retrusion was always observed in a child (11.1%) postoperatively. The condylar surface appeared unsmooth in panoramic radiographs of 2 (22.2%) cases. Objective measurements showed that a patent (11.1%) had an opening deflection and a limited laterotrusion at the return visits. SNB angles of all cases were within the normal range 5 years after the operation. CONCLUSION Surgery with ORIF is a relatively safe and effective method for pediatric MCF. The future growth of the mandibular condyle and the long-term TMJ function are lightly influenced in patients postoperatively.

Abstract
Treatment of craniomaxillofacial (CMF) trauma in dogs often requires a multidisciplinary approach and a thorough understanding of the CMF skeletal structures involved. The aim of this retrospective study was to use a large number of CT studies of dogs evaluated for CMF trauma and to describe fracture location and morphology in relation to demographic data and trauma etiology. The medical records and CT studies of 165 dogs over a 10-year period were evaluated. The skeletal location of CMF fractures as well as the severity of displacement and fragmentation of each fracture was recorded. Patient demographic data and trauma etiology were also recorded. Animal bites accounted for the majority of trauma (50%), followed by unknown trauma (15%), vehicular accidents (13%), and blunt force trauma (13%). Small dogs, <10 kg, and juveniles accounted for the majority of patients (41.8 and 25.5%, respectively). The most likely bone or region to be fractured was the maxillary bone, followed by the premolar and molar regions of the mandible. Up to 37 bones or regions were fractured in any given patient, with an average of 8.2 fractured bones or regions per dog. The most commonly fractured location varied according to trauma etiology. Specifically, vehicular accidents tended to result in more locations with a higher probability of fracture than other trauma types. A major conclusion from this study is that every bone of the CMF region was fractured in at least one case and many cases had a large number of fractured regions. Thus, the need for comprehensive assessment of the entire CMF region, preferably using CT, is underscored.
