Gong P, Wang L, Zhao L, Zheng P, Long J. Assessment of the relationship between the three-dimensional precise location of the mandibular third molar and the volume ratio of the impacted mandibular third molar to the mandibular angle, and the patterns of mandibular angle fracture: A retrospective study. J Craniomaxillofac Surg 2024:S1010-5182(24)00239-7. [PMID: 39181741 DOI: 10.1016/j.jcms.2024.08.009] [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: 03/12/2024] [Revised: 04/23/2024] [Accepted: 08/19/2024] [Indexed: 08/27/2024] Open
Abstract
This study aimed to evaluate the relationship between the precise three-dimensional location of the third molar (M3) and mandibular angle fracture (MAF) patterns and to assess the effect of the volume ratio occupied by M3 in the mandibular angle on fracture patterns. The location of M3 was assessed in 218 patients with MAF using computed tomography reconstruction. The bone volume of the mandibular angle and the bone volume occupied by M3 were measured to calculate the volume ratio of M3 to the mandibular angle (M3/MA). MAF patterns were categorized into simple fracture (Type I), displaced fracture (Type II), and comminuted fracture (Type III) based on fracture severity. The results showed that the location of M3 significantly influenced MAF patterns (vertical position: P = .001; horizontal position: P = .002; angulation: P = .027, respectively) and the volume ratio of M3/MA was significantly higher for Type III fracture than Types I and II (P < .001). Regression analysis showed that the horizontal position and angulation of M3 and the volume ratio of M3/MA were the main predictors for comminuted MAF. A larger volume ratio (odds ratio [OR], 1.201; 95% confidence interval [CI], 1.037-1.391; P < .014), Class III position (OR, 7.978; 95% CI, 1.275-49.910; P < .026), and horizontal angulation (OR, 7.212; 95% CI, 1.028-50.581; P < .047) of the M3 were more prone to comminuted MAF than simple fracture. Our findings indicate that the location of M3 significantly affects MAF patterns, and that M3 may weaken the mandibular angle by occupying more bone space, thereby increasing the risk of a comminuted fracture.

Abstract
The clinical finite element analysis (FEA) application in maxillofacial surgery for mandibular fracture is limited due to the lack of a validated FEA model. Therefore, this study aims to develop a validated FEA model for mandibular fracture treatment, by assessing non-comminuted mandibular fracture fixation. FEA models were created for mandibles with single simple symphysis, parasymphysis, and angle fractures; fixated with 2.0 mm 4-hole titanium miniplates located at three different configurations with clinically known differences in stability, namely: superior border, inferior border, and two plate combinations. The FEA models were validated with series of Synbone polymeric mandible mechanical testing (PMMT) using a mechanical test bench with an identical test set-up. The first outcome was that the current understanding of stable simple mandibular fracture fixation was reproducible in both the FEA and PMMT. Optimal fracture stability was achieved with the two plate combination, followed by superior border, and then inferior border plating. Second, the FEA and the PMMT findings were consistent and comparable (a total displacement difference of 1.13 mm). In conclusion, the FEA and the PMMT outcomes were similar, and hence suitable for simple mandibular fracture treatment analyses. The FEA model can possibly be applied for non-routine complex mandibular fracture management.

Abstract
Introduction Mandibular angle fracture (MAF) is the second most common site of all fractures of the mandible with the highest complication rate. Management of MAF has evolved in the past four decades. The purpose of the prospective study was to compare the efficacy of new design titanium miniplate (NDM) with conventional titanium miniplate (CTM) in the treatment of MAF. Objectives Mouth opening, occlusion, bite force measurement, and radiographs compared preoperatively and first week, first month and third month postoperatively. Materials and Method Fourteen patients diagnosed with MAF were randomly divided into two groups: Group A (seven patients) was treated with NDM and Group B (seven patients) with CTM. Patients were assessed preoperatively and postoperatively at an interval of one week, one month and three months. Results Repeated measures ANOVA and Post hoc Tukey test showed a significant increase in bite force and mouth opening for both groups in first and third postoperative months. Unpaired t-test showed slightly better mouth opening in Group B and slightly higher bite force in Group A. Discussion Both miniplates fulfilled all the study objectives and equally satisfactory healing was seen at the end of third month. NDM offers better stability, rigidity, and anatomic reduction of the fracture with a drawback of difficulty in adaptation and increased operative timing compared to CTM. Hence, we would like to conclude that both miniplates are equally efficient in the treatment of non-comminuted angle fractures with the NDM having upper hand in stability.

Abstract
Background Mandible is the only mobile facial jaw bone and it aides in various functions such as phonation and mastication. Therefore, management of mandible fracture becomes inevitable due to its functional and anatomical importance. Fracture fixation methods and techniques have steadily evolved with various osteosynthesis systems. In this article, we discuss the management of mandible fracture using a newly designed two-dimensional (2D) hybrid V-shaped plate. Purpose In this paper, we have evaluated the efficacy of the newly developed 2D V-shaped locking plate in the management of mandibular fractures. Method We have assessed 12 cases of different mandibular fractures ranging from symphysis, parasymphysis, angle and subcondylar region. Treatment outcome was assessed both clinically and radiologically at regular intervals with various intraoperative and postoperative parameters. Result Results of this study suggest that fixation of mandible fracture with the 2D hybrid V-shaped plate facilitates anatomic reduction and functional stability and carries a low morbidity and infection rate. Conclusion The 2D anatomic hybrid V-shaped plate can be a suitable alternative to conventional miniplate and 3D plates as it offers satisfactory anatomic reduction and functional stability. Positioning the plate in relation to the mental nerve and plate adaptation along the angle region are much easier.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2022; 123:610-615. [PMID: 35545189 DOI: 10.1016/j.jormas.2022.05.008] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 03/17/2022] [Accepted: 05/05/2022] [Indexed: 11/15/2022]
Abstract
The purpose of this study is to explore the effectiveness of Cfr-PEEK, in the fixation of unfavorable fractures of mandibular angulus by comparing it with the titanium and resorbable biomaterials. 8 different fixation models were created. In the first 4 groups, a single mini plate was applied to the upper edge of the fracture line by the Champy method. In the other 4 groups, an additional plate was placed on the lower edge of the fracture line. In these models, titanium, resorbable and Cfr-PEEK plate/screw systems were investigated by the finite element analysis method. The highest Von Mises stress was observed on the upper plate in the group 5 while the lowest was seen in the lower plate in the group 7. The highest stress values on the screws were observed on the screws placed closer to the fracture line. Considering the stresses on the bone around the screws, the highest Pmax and Pmin values were seen in group 5, and the lowest values were seen in the group 7. The highest displacement was observed in the group 3, while the lowest was observed in the group 5. According to the results it can be said that Cfr-PEEK plate/screw systems may provide advantages by decreasing the stresses on the fixation systems over the titanium plates and providing more stable fixation over the resorbable systems. Cfr-PEEK plates of 2 mm thickness seems to be a potential alternative to 1 mm thick titanium plates.

Abstract
Maxillofacial trauma patients comprise a significant subset of patients presenting to emergency departments. Before evaluating for facial trauma, an emergency or trauma physician must perform a primary survey to ensure patient stabilization. Following this primary survey, this document discusses the following clinical scenarios for facial trauma: tenderness to palpation or contusion or edema over frontal bone (suspected frontal bone injury); pain with upper jaw manipulation or pain overlying zygoma or zygomatic deformity or facial elongation or malocclusion or infraorbital nerve paresthesia (suspected midface injury); visible nasal deformity or palpable nasal deformity or tenderness to palpation of the nose or epistaxis (suspected nasal bone injury); and trismus or malocclusion or gingival hemorrhage or mucosal hemorrhage or loose teeth or fractured teeth or displaced teeth (suspected mandibular injury). The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
ABSTRACT The skin redraping method for medial epicanthoplasty is characterized by some shortcomings which warrants modification. In this study, clinical data of 193 patients who underwent medial epichanthoplasty by the modified skin redraping technique or the classic skin redraping technique were reviewed retrospectively. The patients underwent operation between May 2018 and June 2020 and were followed up for not less than 6 months. Interepicanthal distance , interpupillary distance, patient satisfaction, and postoperative complications were evaluated. In terms of interepicanthal distance/interpupillary distance ratio (P > 0.05) and satisfaction score (P = 0.759), the modified skin redraping technique and the classic skin redraping technique were similar. In the classic skin redraping group, there were 3 cases of visible scarring in the lower eyelid, corresponding to significantly more cases than in the modified skin redraping group (n = 0, P < 0.001). There were more out-fold cases in the modified skin redraping group (76/90) than in the classic skin redraping group (17/88) (P < 0.001). Utilizing the modified skin redraping medial epicanthoplasty can prevent medial hooding of the upper eyelid, reduce the probability of visible scarring, and produce more out-fold with concurrent double eyelidplasty compared with classic skin redraping epicanthoplasty.Level of evidence: IV.

Abstract
This article focuses on the different imaging modalities used to evaluate acute mandibular fractures and explores important concepts relating to their diagnosis, investigation, and treatment. Significant focus will be given to exploring general management principles, considerations regarding first-line imaging, and recent technological advancement. Computed tomography (CT) is the preferred method when attempting to identify acute mandibular fractures, particularly in trauma patients, and has very high specificity and sensitivity. Multidetector CT now represents the standard of care, enabling fast scan times, reduced artifact, accurate reconstructed views, and three-dimensional (3D) reconstructions. Cone-beam CT is a newer advanced imaging modality that is increasingly being used worldwide, particularly in the ambulatory and intraoperative setting. It produces high-resolution images with submillimeter isotropic voxels, 3D and multiplanar reconstruction, and low radiation dose, however is less widely available and more expensive. Ultrasound is a valuable method in identifying a fracture in unstable patients, but is limited in its ability to detect nondisplaced fractures. Magnetic resonance imaging is useful in determining the presence of soft-tissue injury. CT angiography is invaluable in the assessment of potential vascular injury in condylar fracture dislocations.

Abstract
INTRODUCTION The mandibular angle endures tension and compression during mastication, and proper internal fixation is essential when a fracture occurs. The authors analyzed the complication rate between Champy technique and rigid fixation, used in the treatment of mandibular angle fracture. METHODS The retrospective study included patients with mandibular angle fracture in single center, from January 2003 to December 2019. The patients were categorized into 2 groups by fixation method of angle fracture: Champy technique which uses single miniplate and rigid fixation which uses multiple miniplate, reconstruction plate, compression plate, lag screw, and wire. Pearson chi-square test was used to analyze the complication rates. RESULTS A total of 64 patients met inclusion criteria. Thirty-four patients had isolated angle fractures and 30 patients had multiple mandibular fractures. In isolated angle fracture, there were no significant differences in all complications between the Champy technique group and rigid fixation group. In multiple mandibular fractures, there were no significant differences in all complications between 2 groups. CONCLUSIONS For isolated angle fractures, Champy technique is a reliable treatment method. Additionally, in case of multiple mandibular fractures, Champy technique is an effective fixation method in angle fractures when proper rigid fixation is performed for accompanying fractures.

Abstract
Aim This study aims to evaluate the clinical outcomes of treatment of mandibular angle fractures using 3D rectangular grid plate. Materials and Methods A total of 10 patients with mandibular angle fractures with or without associated facial fractures requiring open reduction and internal fixation were included in the study. Fixation was done using 3D rectangular grid plate. Results The mean age of the patients in the study is 34.7 years. In all the cases, fracture was adequately reduced (100%) intraoperatively and confirmed through postoperative radiographs. The mean mouth opening by the end of 3 months is 38.60 mm. Four patients had paresthesia of inferior alveolar nerve pre- and postoperatively, and normal sensation was regained by the end of the third month. There were no reported cases of infection and hardware failure during the 9-month follow-up period. Conclusion The results of the study suggest that 3D rectangular grid plate is a feasible alternative to conventional miniplate systems with good clinical outcome and fewer complications related to paresthesia, infection and hardware failure.

Do Splints Play a Role in the Management of Condylar Postfracture Syndrome After Mandibular Angle Fractures?-A Randomized Controlled Clinical Trial. J Oral Maxillofac Surg 2019; 78:241-247. [PMID: 31704268 DOI: 10.1016/j.joms.2019.09.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2019] [Revised: 09/23/2019] [Accepted: 09/24/2019] [Indexed: 10/25/2022]
Abstract
PURPOSE Fractures of the mandibular angle can result in condylar postfracture syndrome (CPFS) due to indirect injury to the condylar region. Studies evaluating early intervention for CPFS are lacking. In the present study, we evaluated the efficacy of interocclusal splint therapy for the prevention and early management of CPFS. PATIENTS AND METHODS A prospective randomized controlled clinical trial was designed and included patients who required open reduction and internal fixation for a unilateral angle fracture. The patients were divided into 2 groups. The study group received interocclusal splints postoperatively and the control group did not receive such splints. The patients were followed up at 2 weeks and 1, 2, and 3 months. The primary outcome measure was the presence or absence of CPFS after 3 months. CPFS was defined as the presence of any 1 of the clinical signs of temporomandibular joint dysfunction. The secondary outcomes included the mean pain scores and degree of mouth opening, which were evaluated at each follow-up visit. RESULTS The study included 40 patients, with 20 patients each randomized to the study and control groups. At the end of 3 months, CPFS was present in 2 patients in the study group and in all 20 patients in the control group. The mean pain scores were significantly lower in the study group than in the control group, and the mean mouth opening was significantly greater. CONCLUSIONS The use of interocclusal splints was found to be effective in the prevention and early management of CPFS. The use of splints also resulted in decreased pain and an improved mandibular mouth opening.

Abstract
The mandibular fracture takes the second position among facial bones fractures, with significant increase of cases in the last years. The aim of this paper is to report a clinical case of a patient with facial trauma due to an automotive accident, resulting in an atypical fracture in a unilateral mandibular angle. In the image examinations an atypical favorable fracture in the right mandibular angle region involving the apex of the erupted 48 tooth was found. The fracture line started in the posterior region of mandibular ramus, below mandibular condyle, and spread out until inferior border of the mandible in premolar region. Despite the atypical design of the mandibular angle fracture described in this paper, the treatment showed satisfactory results, without any aesthetic or functional changes for the patient.

Abstract
BACKGROUND/AIMS Angle fractures represent the largest percentage of mandibular fractures. They pose as a unique entity because of their codependent morphological dynamic factors, rendering the understanding of the mechanism, and treatment challenging. The aim of this study was to analyze the association between the mandibular gonial angle and the risk of mandibular angle fracture while highlighting its clinical relevance. MATERIALS AND METHODS A retrospective analysis of radiographs of patients treated for mandibular fractures was done. The factors studied were as follows: the presence of a high gonial angle and an impacted third molar. The outcome was mandibular angle fracture. The gonial angle was measured using Planmeca Digital Software 3.7.0.R. Status of the third molar was also noted. Data obtained were analyzed using SPSS 22 (IBM Corp, Armonk, NY). RESULTS The sample comprised 70 mandibular fractures (32 angle fractures and 38 non-angle fractures). The mean gonial angle in the angle fracture group was 128.5 ± 5.4º which was 10.2° larger than in the non-angle group (mean 118.5 ± 4.4º; P = 0.0001). Patients with a high gonial angle were 8.7 times more likely to sustain an angle fracture than those with normal or low gonial angles. A statistically significant relationship between the presence of impacted third molar and patients sustaining mandibular angle fractures was noted (P = 0.0001). CONCLUSION Subjects with a high gonial angle and an impacted third molar are at an increased risk for mandibular angle fracture due to direct and indirect morphological factors.

Abstract
PURPOSE The purpose of this study was to compare the integrity of human mandibular angle fracture after fixation with a single titanium plate along the upper lateral border with that of the native human mandible. MATERIALS AND METHODS This cross-sectional anatomic study involved the left hemimandibles of 16 human cadavers. They were selected and divided in 2 groups by remaining dental status. Additional predictor variables, such as height of the left mandibular body and gender, were noted. Left hemisected native mandibles were mounted at the condyle and loaded on an Instron 5565 mechanical unit (Instron Corp, Norwood, MA) until fracture. Fractured left hemimandibles were fixated with a titanium miniplate and screws. After plate fixation, each hemimandible was reloaded on an Instron 5565 until fracture. Data pertaining to primary outcomes of load application were recorded in newtons at displacement values of 3.0, 5.0, and 7.0 mm and at displacement at fixation failure. Primary outcomes of maximum load and displacement at maximum load were recorded in newtons and millimeters, respectively. Descriptive statistics were used to summarize sample characteristics. Statistical comparisons were performed using t test, χ2 (or Fisher exact) test, and linear regression. Pearson correlation was used to examine relations between select biomechanical measurements. RESULTS The study sample was composed of 12 female and 4 male cadaveric hemimandibles. Donors' age at time of death ranged from 54 to 95 years (mean age, 78.94 yr). The mean maximum load in native and plated hemimandibles was 943.56 and 292.57 N, respectively (P < .0001). CONCLUSION Key clinical findings of this study include the inability of single plate mandible fixation to restore the mandible to preinjury levels and verification that gender, dental status, and height of the mandible do not alter the stability of a single plate fixated mandible.

Abstract
Aim: Malfixed miniplates can impair fracture healing, and the screw pilot holes may widen during repeated fixation trials. This in vitro study explored the extent to which screw fixation of mandibular angle fractures could be improved by augmenting the drilling holes with polymethylmethacrylate (PMMA). Materials and Methods: We measured stabilization by recording specimen displacement under a vertical force of 50 N applied using a hydraulic tester. We included 20 hemimandibles from sheep (average weight 40 kg). The specimens were randomly divided into two groups of 10 and pilot holes were created in the angulus region using a drill 1.2 mm in diameter. Next, we performed osteotomies simulating angulus fracture repair. In group 1, the fracture site was fixed using non-compression miniplates and four screws were inserted to the maximal possible extent employing a mechanical screwdriver. In group 2, the pilot drill holes were filled with PMMA prior to miniplate fixation. Then vertical forces of 50 N were applied to the molar region and the displacements were measured. The Shapiro-Wilks test was used to compare the two groups. Result: The maximum average displacement in the experimental group was significantly lower than that in the control group (p=0.026). Thus, PMMA-augmented screws better stabilized bone, affording reliable fixation.

Abstract
After the nasal bones, the mandible is the second most common site of facial fractures, and mandibular fractures frequently require open reduction. In the trauma injury setting, multidetector computed tomography (CT) has become the cornerstone imaging modality for determining the most appropriate treatment management, fixation method, and surgical approach. Multidetector CT is also used to assess the adequacy of the reduction and evaluate potential complications in the postoperative period. For successful restoration of the mandible's form and function, as well as management of posttraumatic and postoperative complications, reconstructive surgeons are required to have a detailed understanding of mandibular biomechanics, occlusion, and anatomy. To provide added value in the diagnosis, treatment planning, and follow-up of mandibular fractures, radiologists should be aware of these concepts. Knowledge of the techniques commonly used to achieve occlusal and anatomic reduction and of the rationale behind the range of available treatment options for different injury patterns-from isolated and nondisplaced fractures to multisite and comminuted fractures-also is essential. This article focuses on the use of multidetector CT for pre- and postoperative evaluation of mandibular fractures and outlines fundamental concepts of diagnosis and management-beginning with an explanation of common fracture patterns and their biomechanical underpinnings, and followed by a review of the common postoperative appearances of these fractures after semirigid and rigid fixation procedures. Specific considerations regarding fractures in different regions of the tooth-bearing and non-tooth-bearing mandible and the unique issues pertaining to the edentulous atrophic mandible are reviewed, and key features that distinguish major from minor complications are described.

Abstract
PURPOSE This prospective study was conducted to evaluate the efficacy of stainless steel single linear miniplate with rectangular grid plate in the treatment of mandibular angle fractures. METHODS This study included 30 patients who were allocated randomly into two groups of each. Group 1 patients were treated with single 2 mm × 4 hole linear stainless steel miniplate and group 2 patients with 2 mm × 4 hole rectangular grid plate. Patients were evaluated for fracture stability, occlusion, mouth opening, and complications at 1st week, 1 and 3 months post operatively. RESULTS There were no significant differences between the two groups with respective variables statistically. In group 1 20 % (n = 3) had mild occlussal derangement 6.66 % (n = 1) patient had deranged occlusion at 1 week post operatively and 13.3 % (n = 2) had mild derangement at 1 month post operatively. In group 2 6.66 % (n = 1) had mild derangement at 1 week postoperatively. 20 % (n = 3) had limited mouth opening at 1 week in group 1 and 13.3 % (n = 2) in group 2. All patients in both groups achieved adequate mouth opening by the end of 3 month. None of the patients in both groups had plate fracture, screw loosening, non union or mal-union. CONCLUSION Within the limits of the study, use of rectangular grid plates for fixation of mandibular angle fractures was reliable with low complication rates, easy adaptation and an effective alternative to conventional miniplates. Further clinical studies with larger sample size can derive a more comprehensive conclusion.
