Abstract
BACKGROUND Mandibular fractures are common facial fractures, and contemporary management of mandibular condylar fractures is controversial. The purpose of this study was to compare the outcomes of patients who sustained a mandibular condylar fracture between 2016 and 2020, who were managed by either open or closed techniques. The outcomes of this study were: post-operative facial nerve function, occlusion, and maximal mouth opening. METHODS This study is a retrospective multicentre cohort study which assessed clinical records for 246 patients with mandibular condyle fractures in three hospitals in Perth, Western Australia. The primary outcome measure was changes in post-operative facial nerve function. RESULTS One hundred and thirty-two patients underwent open reduction and internal fixation (ORIF), and 114 patients had closed management. The overall rate of temporary facial nerve injury following ORIF was 3.28%. The overall rate of permanent facial nerve injury was 0.82%. Sialocoele occurred in 2.46% of all patients who underwent ORIF. 6.14% of patients had persisting malocclusion across both groups. There was a statistically significant association between the degree of fragment shortening and facial nerve injury (P = 0.0063), with more facial nerve changes in the group with 5 mm or greater of fragment shortening. CONCLUSIONS There is still significant debate over the management of mandibular condylar injuries. This study demonstrates a similar rate of temporary and permanent facial nerve injury as previously described, as well as a similar rate of sialocoele occurrence. Further prospective studies may provide clarity about important characteristics that will help guide decision making for mandibular condylar fractures.

Abstract
Our study aims to estimate the prevalence of surgical site infections (SSI) following open reduction and internal fixation (ORIF) for mandibular fractures and to determine the effect of potential moderators on it. A systematic literature search (Medline and Scopus databases) was conducted independently by two reviewers. The pooled prevalence with 95% confidence intervals was estimated. Quality assessment as well as outlier and influential analysis were performed. Additionally, subgroup and meta-regression analysis were conducted in order the effect of categorical and continuous variables on the estimated prevalence to be investigated. In total, seventy-five eligible studies (comprising a sum of 5825 participants) were included in this meta-analysis. The overall prevalence of SSI following ORIF for mandibular fractures was estimated as high as 4.2% (95% CI 3.0-5.6%) with significant heterogeneity between studies. One study was identified to be critically influential. In the subgroup analysis, the prevalence was 4.2% (95% CI 2.2-6.6%) among studies conducted in Europe, 4.3% (95% CI 3.1-5.6%) among studies conducted in Asia and higher among those conducted in America (7.3%) (95% CI 4.7-10.3%). It is important for healthcare professionals to be aware of the etiology of these infections, despite the relatively low rate of SSI in these procedures. However, further, well-designed prospective and retrospective studies need to be conducted in order this issue to be fully clarified.

Abstract
The purpose of this study was to evaluate the reliability and reproducibility of a novel approach for base and neck fractures of the mandible. An anatomical study was conducted on 22 given to Science subjects. A rhytidectomy-like approach was performed, followed by a transmasseteric anteroparotid dissection. Measures were taken of the incision length and bone exposure at every step. The identification of a ramus of the facial nerve during dissection was noted. The subjects were classified according to their facial adiposity. A correlation coefficient was measured between incision length and bone exposure as well as morphotype and bone exposure. Statistical analysis was carried out using the Pearson method for linear correlation, and Chi2 test for further analysis. Adequate condylar exposure was always achieved in the area of interest (i.e. in the main localization of base and neck fractures). There was no correlation between the length of the cranial cutaneous backcut and the bone exposure horizontally (p = 0.3296) or vertically (p = 0.8382). There was no correlation between the total length of the incision and the bone exposure horizontally (p = 0.5171) or vertically (p = 0.8404). There was a significant correlation between the subjects' facial adiposity and the bone exposure horizontally and vertically (p<0.005). This approach allowed adequate bone exposure to the mandible base and neck, with a possible 90° angulation of instruments for optimal bone fixation. The incidence of facial nerve rami identification during dissection was similar to other approaches. The scarring was hidden. These results allowed us to propose this approach in a clinical study.

J Maxillofac Oral Surg 2022; 21:916-922. [PMID: 36274863 PMCID: PMC9474963 DOI: 10.1007/s12663-021-01565-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Accepted: 04/10/2021] [Indexed: 11/28/2022] Open
Abstract
Purpose This paper retrospectively analyses the functional outcomes and complications associated with pre-auricular transparotid approach for the management of mandibular condylar fractures. Material and Methodology The retrospective data of 82 condylar fractures were analysing in 73 patients who underwent open reduction and internal fixation with pre-auricular transparotid approach. Evaluation of post-operative complications and the post-operative occlusion status, maximal inter-incise opening, adequacy of reduction and stability of fixation were assessed clinically and radiographically. Results The exposure of fracture segment was adequate in all the cases, and fixation was easy with 2 mm delta miniplate. Transient facial nerve palsy occurred in 2 patients (2.43%). 1 patient developed sialocele which was managed conservatively. There were slight occlusal discrepancies in 10 patients at the end of 1-week follow-up which was corrected with guiding elastics at the end of 1-month follow-up. The reduction was adequate, and fixation was stable. The functional outcomes were satisfactory in term of mouth-opening and range of motion. Conclusion The pre-auricular transparotid approach provides direct access to the fracture site resulting in less retraction of the tissue containing facial nerve and also less amount of periosteal stripping is required, thus it maintains good vascularity to the fracture segments. It provides direct visualization of the fracture without much retraction of the tissue containing facial nerve branches. It allows better fixation of the fracture with very less complication which results in good functional outcomes.

Abstract
As 2D quantitative measurements are often insufficient, a standardized 3D quantitative measurement method was developed to analyze mandibular condylar fractures, and correlate the results with the mandibular condylar fracture classifications of Loukota and Spiessl and Schroll and clinical parameters. Thirty-two patients with a unilateral mandibular condylar fracture were evaluated using OPT, 2D (CB)CT images, and 3D imaging to measure the extent of the fractures. The maximum mouth opening (MMO) was measured. Ramus height loss could be measured only in OPT, but not in 2D CT images. The Intraclass Correlation Coefficient was excellent in the 3D measurements. In the Loukota classification, condylar neck fractures had the largest median 3D displacement and the highest rotations of the fracture fragments. The largest fracture volume was observed in base fractures. According to the Spiessl and Schroll classification, type V fractures had the largest median 3D displacement and the highest rotation in the X-axis and Z-axis. Type I fractures had the largest fracture volume. We found a moderate negative correlation between MMO and 3D displacement and rotation on Z-axis. The 2D quantitative analysis of condylar fractures is limited, imprecise, and not reproducible, while quantitative 3D measurements provide extensive, precise, objective, and reproducible information.

Abstract
Condylar fractures alone accounts to about 25% to 40% of all the fractures of mandible. Management of condylar fractures has always been a controversy. Nowadays there has been more emphasis on open reduction of condylar fractures by the surgeons.The reasons could be the result of complications of closed reduction where the patient may not be able to masticate properly and deviation still present thereby the structural and functional loss forcing the surgeons' choice to open up. The anterior parotid approach has lesser risk of injury to parotid gland and also to facial nerve we attempted to use mini retro mandibular access for such fractures. So the aim was to explore the feasibility of the mini retro mandibular approach to sub condylar fractures. The patients reported to the department of oral and maxillofacial surgery department clinically and radio logically diagnosed and treated for condylar fractures were included. The maximal mouth opening, protrusive and lateral excursive movements, midline orientation with opposing arch, scar visibility, sialocele and facial nerve weakness were all recorded post operatively and compared with pre-operative recording. The mini retro mandibular access with anterior parotid transmessetric approach to sub condylar fractures can be the choice for the surgical management of sub condylar fractures which is absolutely easy, reliable, with less visible scar and with less chances of landing in facial nerve complications.

Abstract
Background Conservative treatment, including observation and closed treatment, as well as open reduction and internal fixation are existing options for treating condylar process fractures. Extraoral approaches are widely preferred for open reduction and internal fixation. Transoral access for condylar base and neck fractures is not yet commonly used as it is technically demanding and requires special equipment. Purpose In this study, the transoral endoscopically assisted approach is described, and its outcomes and complications were investigated. Imaging data and clinical records of 187 patients with condylar process fractures, treated via endoscopically assisted transoral approach between 2007 and 2017 were analyzed. Parameters included diagnosis and fracture classification, treatment, osteosynthesis configuration and postoperative complications. Results Early complications, including infection, transient postoperative malocclusion, pain and limited mouth opening, occurred in 35 patients (18.7%). Late onset complications, such as screw loosening were documented in only 4 patients (2.1%). Revision surgery following postoperative 3D imaging was required in only 3 cases (1.6%). Fragment length ranged from 15.5 to 38.3 mm. In 57.7% of patients with condylar fragment length < 20 mm, a single osteosynthesis plate was used, with no elevated complication rate. Two osteosynthesis plates with 4 screws each was used as standard in longer fragments. Conclusion Endoscopically assisted transoral treatment of condylar process fractures is a reliable, yet technical demanding technique. It allows for reduction and fixation of fractures with a condylar fragment length of > 15 mm with low postoperative complication and revision rates.

Abstract
ABSTRACT Mandibular fractures are the third most frequents maxillo-facial fractures. Most frequent site is the subcondylar region. Different approaches to reach subcondylar region, have been described. In the study was evaluated the advantages of neuromuscular block during endoscopic surgery for subcondylar fractures. Twenty-five patients affected by subcondylar fractures were enrolled in this study and divided in 2 groups; group A: patients who received an intraoperative booster of curare during surgical procedure and group B patients who underwent surgery treated without the intraoperative booster of curare. All patients were treated successfully by endoscope-assisted transoral approach. The analysis of time required for surgery showed a reduction in group A comparing to group B. The mean time for surgery for the patients in group B with displacement between 0° and 45° was 170 minutes, and for 45° to 90° was 230 minutes. In group A, the mean time was 117.5 minutes for patients with condylar displacement between 0° and 45°, and 147.5 minutes for the other group. In conclusion, deep neuromuscular block seems to improve the surgical conditions in patients undergoing subcondylar endoscopic assisted surgery, further study needs to assess this surgical technique in order to better define this surgical protocol.

Abstract
The aim of the study was to conduct a randomized clinical trial comparing the efficacy of standard non-compression miniplate and 3-dimensional (3D) titanium plate in the open reduction internal fixation (ORIF) of the mandibular condylar fractures. Patients who underwent open reduction of mandibular condylar fracture were recruited for the study. The patients satisfying the inclusion criteria were randomly assigned to two groups in a 1:1 ratio. Group A comprised patients treated using conventional miniplates, and Group B comprised patients treated using 3D Delta Plate. Informed consent was provided. All the patients underwent ORIF under GA via retromandibular approach. The sample size was set at 20 participants, with 10 participants in each group who were randomly allocated. Our study showed that patients in Group A had a significant statistical difference operating time (141.20 ± 2.59 min) than that of Group B (117.2 ± 9.63 min). Mouth opening was significantly greater in the 3rd-month follow-up in Group B (mean = 42.40 ± 1.82) compared to Group A (mean = 35.80 ± 1.30). Biting efficiency in Group B was observed to be clinically and statistically better compared to Group A (P = 0.012). Wound dehiscence was managed efficiently by judicious use of antibiotics and wounds were free of any signs of infections or discharge in the consecutive follow-ups. No plate removal was required in either group. Patients treated with 3D delta plates have superior outcomes with regard to operation time, mouth opening, and biting efficiency compared with miniplates. Hence, it can be concluded that the triangular shape of the 3D Delta plate allows the stress distribution to be superior and multidimensional, leading to better post-operative stability, faster healing, and reduced complications.

Abstract
Introduction: Condylar fractures make up for an average of 17.5%–52% of all mandibular fractures. The aim of the present study was to compare the ease, success, and complications between retromandibular and periangular transmasseteric approaches when used for open reduction and internal fixation of condylar fractures. Materials and Methods: A total 20 cases with condylar fracture, ten each for retromandibular and periangular transmasseteric approach, were included in the study. Patients were evaluated at 1 week, 1 month, 3 months, and 6 months. Postoperative occlusion, maximum mouth opening, range of movement, facial nerve function, visibility, convenience of plating, and time taken for exposure, fixation, and closure were recorded. Incidence of complications such as wound dehiscence, wound infection, hematoma, sialocele formation, Frey's syndrome, and hypertrophic scars were also evaluated. Results: The mean exposure time in the retromandibular approach was 10 min 31 s and 9 min 17 s in the periangular transmasseteric approach. The incidence of facial nerve injury was 2 of 10 patients in the retromandibular group and 3 of 10 patients in the periangular transmasseteric group, all of which resolved within 6 months. The incidence of sialocoele was 2 of 10 in the retromandibular group. The time taken for exposure of the fracture site was statistically significant between the two approaches (P = 0.048) with longer time required for retromandibular approach. Discussion: It can be summarized that both the approaches are comparable and well suited for surgical management of condylar fractures. It was observed that in displaced condylar neck fractures, greater difficulty was experienced in the periangular transmasseteric approach than the retromandibular approach.

Abstract
This study assessed the efficacy of the retromandibular antero-parotid approach for open reduction and internal fixation (ORIF) of subcondylar fractures. Sixty patients with the mean age of 31.03 years underwent surgical reduction with a 20–25mm incision in the retromandibular area with an antero-parotid transmasseteric approach. All patients were followed between 6 to 12 months. At the end of the first week, six patients exhibited postoperative malocclusion. At the next visits, all patients had optimal occlusion. Maximal interincisal opening (MIO) of 56 patients (93.3%) was >37mm, and only four patients (6.7%) had MIO<37mm. In three patients (5%), weakness of the buccal branch of the facial nerve was noticed postoperatively. No salivary gland complications were seen. The surgical scar was hardly noticeable. Retromandibular access with transmasseteric antero-parotid approach is the technique of choice for treatment of high- and low-level subcondylar fractures with adequate visibility and direct access to the condylar area.

A Systematic Review and Meta-Analysis. J Oral Maxillofac Surg 2020; 78:1795-1810. [PMID: 32554064 DOI: 10.1016/j.joms.2020.05.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 05/08/2020] [Accepted: 05/08/2020] [Indexed: 11/28/2022]
Abstract
PURPOSE The aim of the present systematic review was to determine whether closed treatment (CLT) with intermaxillary fixation (IMF) is superior or equivalent to open reduction and internal fixation (ORIF) in the management of unilateral displaced subcondylar fractures regarding the range of mandibular motion. MATERIALS AND METHODS To address our question, we conducted a systematic review and meta-analysis of the reported data after a comprehensive manual and electronic database search of studies reported up to 2017 in the English language that had compared CLT and ORIF of mandibular condyle fractures in adults. The following outcomes were recorded: maximum interincisal opening (MIO), protrusive movement (PM), lateral excursion toward the fractured side (LEFS), and lateral excursion toward the nonfractured side (LENFS). RESULTS The search resulted in 8 studies, 4 of which were included in the meta-analysis. The MIO and PM showed no statistically significant differences, with an effect size of -0.823 (P = .112) and -0.633 (P = .079), respectively. However, the LEFS and LENFS were superior after CLT, with an effect size of -0.710 (P = .031) and -0.682 (P = .017), respectively. CONCLUSIONS The findings from the present review suggest that both ORIF and CLT can provide comparable MIO and PM in subjects with unilateral displaced subcondylar fractures. However, CLT was superior to ORIF for both LEFS and LENFS.

Abstract
The aim of this study was to evaluate the effects of protecting the facial nerve and reducing the scar visibility using a modified tragus edge and transmasseteric anteroparotid approach compared to classic preauricular approach for intracapsular and condylar neck fractures. This retrospective study included 64 patients (78 sides) who underwent surgical treatment for intracapsular or condylar neck fractures from January 2014 to June 2018. Patients were divided into the experimental group (treated via a modified tragus edge and transmasseteric anteroparotid approach), and the control group (treated via the classical preauricular approach). Therapeutic outcome assessment parameters included facial nerve injury, salivary fistulae, wound infection, restricted mouth opening, postoperative occlusion disorders, and scar visibility. In the control group, there were 3 cases of facial nerve injuries and 2 cases of salivary fistulae. One case of temporary facial nerve injury occurred in the experimental group, with complete recovery within 1 month. The scars were less visible in the experimental group than in the control group. These results suggest that a modified tragus edge and transmasseteric anteroparotid approach reduced the incidences of facial nerve injuries, minimized the scar visibility, improved exposure of the operative site and fixation of titanium screws or plates, and did not increase the frequency of other complications.

Abstract
INTRODUCTION The potential drawbacks of surgical approaches to neck and base fractures of the mandibular condyle (visible scare, facial nerve injury) are still considered by many surgeons as a brake for open reduction and internal fixation. The aim of our study was to analyze the results in terms of access, scare quality and complications that could be noticed in a 12 years period of time with the use of the high sub-mandibular approach (HSMA) we first described in 2006 for the surgical treatment of neck and base fractures. MATERIAL AND METHOD All the files of patients operated on for condylar neck and base fractures approached by mean of a HSMA between January 2006 and December 2018 in our department and containing information concerning age, sex, type of fracture, kind of osteosynthesis material, operating time, name of the surgeon, postoperative complication linked to the approach, scare quality at 6 months follow-up at least were included. The skin incision and the dissection planes followed the original publication of Meyer et al. in 2006. RESULTS 434 patients (sex ratio: 2.06, mean age: 32, 496 approaches) met the inclusion criteria. Following the AO classification, 21.2% of the fractures were classified as neck fractures and 78.8% as base fractures. 97.6% of all fractures were stabilized by mean of a 3D plate (TCP® plate, Medartis, Basel-CH), the remaining ones by mean of a combination of 1.2, 1.5 and 2.0 straight plates. Mean operating time was 40minutes per side. Patients were operated on by senior surgeons in 71.7% of the cases and by trainees under supervision for the others. Concerning the complications linked to the approach, we noticed 11 (2.2%) temporary (0 definitive) paresis of the facial nerve, 1 (0.2%) hematoma and 1 (0.2%) abscess that both needed revision. Scare was hypertrophic or considered as unaesthetic by the patient in 5 cases (1%). DISCUSSION The HSMA, if performed as initially described, is a safe and quick procedure compared to other cutaneous approaches. It gives access to all base fractures and to most of neck fractures. The very low rate of facial nerve complications is mainly explained by the plane by plane dissection making it very easy to avoid the facial nerve branches or to check them when encountered. The HSMA is particularly suited to the use of TCP plates as the upper holes of these plates, placed horizontally, are easy to reach from below. The HSMA is therefore still our preferred cutaneous approach to the condylar process.

Abstract
INTRODUCTION In surgical approaches to condylar fractures, there is a risk of damage to the transverse facial artery (TFA) which may in turn account for impaired blood supply to the temporomandibular joint (TMJ). In order to investigate the risk of damage to the TFA, and prevent lesions to this artery resulting from TMJ surgical procedures, we studied the distance between the TFA and the head of the condylar process. METHODOLOGY A dissection study was conducted on 10 fresh cadavers (20 condylar specimens dissected), involving fifty CT scans of the face with intravenous contrast. Vertical distance from the TFA to the top of the mandibular condyle head and distance from the TFA to the lateral aspect of the mandibular condyle were measured. RESULTS The lateral aspect of the mandibular condyle is vascularized by branches emanating from the superficial temporal artery (STA) and the TFA. The TFA was located 1.84 ± 0.6 cm below the condylar process of the mandible and ran 1.09 ± 0.54 mm lateral to the head of the mandibular condyle. DISCUSSION In order to spare the TFA in fractures involving the condylar neck, surgical approaches to the condyle should preserve the uppermost 2 cm of the lateral surface of the condyle during dissection. Due to the necessity for periosteal elevation of the lateral surface of the condyle in condylar head fractures, it is possible to spare the TFA, running lateral to the condylar neck, and the medial condylar surface in order to leave the branches that derive from the maxillary artery (MA) intact.

Abstract
Background The purpose of this study was to compare the outcomes and effectiveness between intraoral approach and retromandibular approach for treatment of subcondylar fracture of mandible. Methods Between March 2011 and October 2013, 24 patients with subcondylar fractures of the mandible were treated by a single surgeon with an intraoral approach using an angulated screwdriver (n = 14) or by another surgeon using a retromandibular approach (n = 10). The interincisal distance was measured 1 week (T0), 6 weeks (T1), 3 months (T2), and 6 months (T3) postoperatively. We also compare the average operation time and the cost of operation between the two groups. Results At 6 months postoperatively, all 24 patients achieved satisfactory ranges of temporomandibular joint movement, with an interincisal distance > 40 mm without deviation and with stable centric occlusion. The intraoral group had the median interincisal distance of 14 mm at T0, 38 mm at T1, 42.5 mm at T2, and 43 mm at T3, while the retromandibular group had that of 15, 29, 35, and 42.5 mm respectively. There was no statistically significant difference between the intraoral and the retromandibular group at T0 and T4. However, significant differences were noted T1 and T2 (p < 0.01). The differences of average operation time between the intraoral (81 min) and retromandibular group (45 min) were statistically significant (p < 0.01). The cost of an operation was 369.96 ± 8.14 (United States dollar [USD]) in intraoral group and was 345.48 ± 0.0 (USD) in retromandibular group. The differences between the two groups were statistically significant (p < 0.01). Conclusion In open reduction of a subcondylar fracture of the mandible, a intraoral approach using an angulated screwdriver is superior to the retromandibular approach in terms of interincisal distance, although the operation time is longer.

Abstract
The aim of this study was to investigate the probability of facial nerve injury (FNI) in the treatment of condylar neck and subcondylar fractures (CN/SCFs) with percutaneous approaches and to identify factors predicting FNI. The data of 80 patients with 87 CN/SCFs were evaluated retrospectively. The primary outcome was FNI occurrence. The predictor variables were age, sex, aetiology, alcohol consumption, fracture site and pattern (dislocation or not), concomitant fractures, time interval to surgery, surgeon experience, plate type, and the dual classification of percutaneous approaches. The approaches were classified based on whether subcutaneous dissection traversed the marginal mandibular branch (MMB) deeply (deep group: submandibular and retroparotid approaches) or superficially (superficial group: transparotid, transmasseteric anteroparotid (TMAP), and high cervical-TMAP approaches). Twenty-two patients (27.5%) suffered FNI, of whom two in the deep group had permanent paralysis of the MMB. In the multivariate logistic regression model, deeply traversing surgery approaches (odds ratio 12.4, P=0.025) and the presence of a dislocated fracture (odds ratio 6.66, P=0.012) were associated with an increased risk of FNI. These results suggest that percutaneous approaches in the superficial group should be recommended for the treatment of CN/SCFs to reduce the risk of FNI.

Are Facial Asymmetry and Condylar Displacement Associated With Ramal Height and Treatment Outcomes in Unilateral Condylar Fracture When Managed by the Closed Method? J Oral Maxillofac Surg 2018; 77:789.e1-789.e8. [PMID: 30576677 DOI: 10.1016/j.joms.2018.11.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Revised: 11/12/2018] [Accepted: 11/12/2018] [Indexed: 10/27/2022]
Abstract
PURPOSE This study measured the mandibular ramal height in patients with unilateral condylar fractures managed by the closed method using elastic intermaxillary fixation. Its correlation with facial asymmetry and condylar displacement was assessed. This will determine whether the treatment outcome is in favor of the closed or open method. MATERIALS AND METHODS A prospective cohort study was performed. The study included patients with unilateral condylar fractures who reported to SDM Craniofacial Surgery and Research Centre, Dharwad, India. All patients in the study were managed by the closed method (nonsurgically using arch bars and elastic intermaxillary fixation). Standardized panoramic radiographs were used to assess ramal height and condylar displacement in the sagittal plane. Posteroanterior mandible and reverse Towne radiographs were used to assess facial asymmetry and condylar displacement in the coronal plane before treatment; immediately after treatment; and at 3, 6, and 12 months of follow-up. Data were subjected to statistical analysis using the analysis-of-variance test and the Pearson correlation coefficient method. RESULTS The study included 25 patients with unilateral condylar fractures managed by closed treatment; they showed a significant reduction in ramal height on the affected side by 1.15 mm (P = .0001) at 12 months' follow-up. The change in facial asymmetry was reported as 1.05 mm (P = .0016) at 12 months' follow-up. Its correlation with ramal height was noted to be insignificant (P = .07). The only significant correlation noted between facial asymmetry and condylar displacement was in the coronal plane at 12 months' follow-up (P = .04). CONCLUSIONS A weak positive correlation was noted among the assessed values on radiographs obtained during the 12-month follow-up. Facial symmetry was not greatly affected when the ramal height at the time of injury on the fractured side was reduced by 3.25 ± 0.6 mm.

Abstract
BACKGROUND Condylar fractures are considered the most controversial mandibular fractures, regarding both the diagnosis and the treatment. With the increase in surgical indications for handling this type of fracture, it is important to discuss about the advantages and disadvantages of the several surgical approaches available. This article describes the surgical details and postoperative results of the mini-retromandibular transparotid approach for treating extracapsular condylar fractures of the mandible. METHODS In a 1-year period, 16 patients affected by extracapsular condylar fractures with surgical indication were treated with the mini-retromandibular transparotid approach. All the surgeries were executed by the same surgeon. Preoperative and postoperative details of each patient were analyzed. RESULTS In the postoperatory, only 2 patients had purulent drainage in the associated fractures area and only 1 patient had paresis of the buccal branch of the facial nerve. No scar issues concerning the surgical wound were observed and reintervention was not necessary in any of the patients. CONCLUSION The mini-retromandibular transparotid approach offers advantages and should be included as an option for the open treatment of extracapsular condylar fractures of the mandible.

Abstract
Objectives The goal of this study was to evaluate the rates of complications, morbidity, and safety with the transparotid approach. Materials and Methods A retrospective study was conducted and consisted of 53 surgically treated patients in the past five years for low condylar neck and subcondylar fractures. Only patients with malocclusion and who underwent open reduction with internal fixation with the retromandibular transparotid approach were included. The examined parameters were postoperative suboptimal occlusion, deflection, saliva fistula, and facial nerve weakness. Results Fifty-three patients had an open reduction with internal fixation on 55 sides (41 males, 77.4%; mean age, 42 years [range, 18-72 years]). Four patients (7.5%) experienced transient facial nerve weakness of the marginal mandibular branch, but none was permanent. Four patients had a salivary fistula, and 5 patients showed postoperative malocclusion, where one needed repeat surgery after one year. One patient showed long-term deflection. No other complications were observed. Conclusion The retromandibular transparotid approach is a safe procedure for open reduction and internal fixation of low condylar neck and subcondylar fractures, and it has minimal complications.

Abstract
PURPOSE This study evaluated the outcomes and complications of the surgical treatment of condylar fractures by the retromandibular transparotid approach. The authors hypothesized that such an approach would be safe and reliable for the treatment of most condylar fractures. MATERIALS AND METHODS A retrospective evaluation of patients who underwent surgical reduction of a condylar fracture from January 2012 to December 2014 at the Clinic of Dentistry and Maxillofacial Surgery of the University Hospital of Verona (Verona, Italy) was performed. Inclusion criteria were having undergone surgical treatment of condylar fractures with a retromandibular transparotid approach and the availability of computed tomograms of the preoperative and postoperative facial skeleton with a minimum follow-up of 1 year. Static and dynamic occlusal function, temporomandibular joint health status, presence of neurologic impairments, and esthetic outcomes were evaluated in all patients. RESULTS The sample was composed of 25 patients. Preinjury occlusion and temporomandibular joint health were restored in most patients. Esthetic outcomes were deemed satisfactory by clinicians and patients. Neither permanent neurologic impairments nor major postoperative complications were observed. CONCLUSIONS According to the results of the present study, the retromandibular transparotid approach is a viable and safe approach for the surgical treatment of condylar fractures.

Abstract
PURPOSE The aim of this article is to present our experience treating fractures of the condylar base with a modification of the high submandibular approach (HSA). MATERIALS AND METHODS Between June 2012 and April 2015, 44 fractures of the condylar base were treated in the Department of Oral and Maxillofacial Surgery of the Medical Hospital of Graz using the modified HSA. RESULTS We did not observe any damage (even transient) to the facial nerve or any complication related to violation of the parotid capsule (such as a salivary fistula, Frey syndrome, or a sialocele). CONCLUSIONS This approach provides good access to the condylar base, ensuring easier internal fixation, excellent protection of the facial nerve and parotid gland, and good cosmetic results.

Abstract
AIM To evaluate the efficacy and safety of the retromandibular approach in the management of condylar fractures by open reduction and internal fixation (ORIF). MATERIALS AND METHODS A total of 20 patients with unilateral mandibular condylar fractures underwent ORIF using retromandibular approach. Pertinent data were collected and subjected to evaluation. RESULTS The retromandibular approach was found to be expeditious in adequately exposing the fracture site and enabling ORIF. The anatomic reduction of the fractured segments and the fixation was satisfactory in all the cases. Average duration of surgery was 39 min (range: 17-56 min) for satisfactory exposure, reduction, and fixation of each condylar fracture. CONCLUSION The retromandibular approach provides adequate exposure of the subcondylar region and should be considered as commendable alternative in the management of condylar fractures.

Abstract
PURPOSE The aim of this study was to evaluate the long-term clinical and radiologic results of the retromandibular transparotid approach to displaced extracapsular subcondylar mandibular fractures. PATIENTS AND METHODS A prospective cohort study was conducted over a period of 5 years on patients surgically treated for displaced extracapsular subcondylar mandibular fractures by the retromandibular transparotid approach. Variables including the type of fracture, degree of mouth opening, fracture displacement, deviation, excursive movements of the mandible, and facial nerve function were monitored before and after treatment. Appropriate statistics were computed. RESULTS Thirty-nine patients with 47 fractures were evaluated. There were 34 subcondylar fractures (located below the sigmoid notch) (87%), and 5 fractures were located in the head region in bilateral cases. Of the fractures, 31 (79%) were unilateral and 8 (21%) were bilateral. In a multivariate study, condylar coronal displacement, coronal sagittal displacement, difference in the ramal height, maximal interincisal distance, protrusive movements, and deviation of the mandible on opening showed statistically significant differences in pretreatment and post-treatment patients (P = .001). The interincisal distance was 46.8 mm (SD, 5.2 mm) postoperatively versus 24.1 mm (SD, 6.7 mm) before treatment. The average range of protrusion was significantly lower (P = .001) in patients before treatment, at 1.9 mm (SD, 1.2 mm), when compared with 6.1 mm (SD, 2.0 mm) postoperatively. During mouth opening, deviation of the mandible is often a sign of compensatory movement of the contralateral joint due to shortening of the ascending ramal height on the affected joint. The mean deviation of the mandible from the midline was 4.2 mm (SD, 1.0 mm) in patients before treatment, with a significant difference (P = .001) in patients after treatment, with a mean of 1.9 mm (SD, 0.995 mm). Temporary injuries to the facial nerve branches were observed in 3 cases (8%) 1 week after treatment, which later resolved within 3 weeks to 3 months. CONCLUSIONS The retromandibular transparotid approach provides good exposure and facilitates accurate reduction and fixation of the subcondylar fragment with positive outcomes, good cosmetic results, and rare major complications. Most facial nerve injuries are transient in nature after this approach. A Synthes 2-mm titanium single mini-plate (West Chester, PA) provides stable results after fixation.

Abstract
BACKGROUND The purpose of this study was to identify factors associated with the decision to perform open reduction and internal fixation of mandibular condylar fractures. METHODS This was a retrospective cohort study of patients with mandibular condylar fractures managed by the plastic and reconstructive surgery, oral and maxillofacial surgery, and otorhinolaryngology services over a 15-year period. Bivariate associations and a multiple logistic regression model were computed for injury characteristics that were associated with open reduction and internal fixation. For all analyses, a value of p ≤ 0.05 was considered significant. RESULTS Six hundred fifty-four condylar injuries were identified in 547 patients. The sample's mean age was 36.0 ± 16.5 years, 20.5 percent were women, and 63 percent were Caucasian. The most common mechanisms of injury were motor vehicle collisions (49 percent), 53.4 percent involved the subcondylar region and 20 percent were bilateral injuries. Associated noncondylar mandibular fractures were present in 60 percent of cases; 20.7 percent were managed with open reduction and internal fixation. The overall complication rate was 21.6 percent. In a multiple logistic regression model, factors associated with an increased likelihood of open reduction and internal fixation were the presence of extracondylar mandibular injuries, condylar neck or subcondylar region injuries, increasing dislocation, and treatment by plastic and reconstructive surgery/oral and maxillofacial surgery (p ≤ 0.04). CONCLUSIONS Increasing severity of mandibular injury, lower level of fracture, joint dislocation, and treatment by plastic and reconstructive surgery/oral and maxillofacial surgery are associated with open reduction and internal fixation of mandibular condylar injuries.

Abstract
PURPOSE The present study was carried out to evaluate the usefulness of mini retromandibular approach on accessibility, scarring and stability in open reduction and internal fixation of sub condylar fractures. MATERIALS AND METHODS Fifteen patients underwent open reduction and rigid fixation of middle and low subcondylar fractures, with mini-retro mandibular approach. RESULTS No signs of infection were observed in any patient postoperatively. Surgical scar was imperceptible and esthetically acceptable in all the cases. Out of 15 patients, only one patient had discrepancy in occlusion and after 2 months satisfactory centric occlusion was achieved. Salivary fistula (parotid fistula) was observed in 3 cases within 1 week postoperatively, which was treated spontaneously with the use of hypertonic saline. Transient facial nerve weakness was observed in 2 patients, in one patient it resolved in 4 weeks postoperatively and in second patient 3 months postoperatively. Mouth opening increased in all the patients with time. Average mouth opening at 1 week interval was 19.6 mm, at 2 months interval 28.2 mm, and after 6 months 38.33 mm suggesting that mouth opening gradually increased with time. At the end of 2 months postoperatively none of the patients had any restriction in lateral movements. At 2 months postoperatively 4 patients had deviation but none of the patients had any deviation 6 months postoperatively. CONCLUSION It is evident from the results of our study that open reduction and internal fixation using mini-retromandibular approach is good treatment option in management of mandibular condylar fractures.

Abstract
Most surgeons agree that closed treatment provides the best results for condylar fractures in children. Nevertheless, treatment of the paediatric mandibular condyle fracture that is severely displaced or dislocated is controversial. The purpose of this study was to investigate the long-term clinical and radiological outcomes following the treatment of displaced or dislocated condylar fractures in children using threaded Kirschner wire and external rubber traction. This procedure can strengthen the advantage of closed reduction and make up for the shortcomings of open reduction. From March 1, 2005 to December 25, 2011, 11 children aged between 4 and 12 years with displaced or dislocated mandibular condyle fractures were treated using threaded Kirschner wire and external rubber traction under portable C-arm fluoroscopy. All patients had unilateral displaced or dislocated condylar fractures. The follow-up period ranged from 24 to 42 months (mean 29.3 months). Normal occlusion and pain-free function of the temporomandibular joint, without deviation or limitation of jaw opening, was achieved in all patients. This closed reduction technique in displaced or dislocated condylar fractures in children offers a reliable solution in preventing the unfavourable sequelae of closed treatment and the open technique, such as altered morphology, functional disturbances, and facial nerve damage.

Abstract
Surgical approaches to the condylar fracture include intraoral, preauricular, submandibular, and retromandibular approaches. Each approach has its own advantages and disadvantages. When a patient needs esthetic results and an intraoral approach is not feasible, the transmasseteric antero-parotid facelift approach is considered. This approach permits direct exposure and allow the surgeon to fixate the fractured unit tangentially. Tangential fixation is critical to osteosynthesis. Disadvantages of the transmasseteric antero-parotid facelift approach include damage to the facial nerve and a longer operation time. However, after the initial learning curve, facial nerve damage can be avoided and operation time may decrease. We report three cases of subcondylar fractures that were treated with a transmasseteric antero-parotid facelift approach. Among these, two cases had trivial complications that were easily overcome. Instead of dissecting through the parotid gland parenchyma, the transmasseteric antero-parotid facelift approach uses transmasseteric dissection and reduces facial nerve damage more than the retromandibular transparotid approach. The esthetic result is superior to that of other approaches.

Abstract
OBJECTIVE This study was conducted to investigate the complications that occur after surgical treatment of sagittal fracture of the mandibular condyle (SFMC). METHODS A retrospective study was conducted on patients in whom SFMC was treated using surgical methods (87 patients, 105 sides) between January 1995 and December 2011 (79 sides were treated by rigid internal fixation and the remaining 26 sides were removed the condylar fragments). The longest follow-up was 17 years, and the shortest was 2 years. Follow-ups were conducted to assess mandibular activity, mouth opening, and computed tomography scans of condylar morphologic alterations. The postoperative complications were evaluated and the causes were analyzed. RESULTS We observed 3 patients with joint ankylosis (all of them were removed the condylar fragments); 8, mouth opening less than 30 mm; 23, deviation on mouth opening at 6 months. At 4 weeks, 19 patients had facial nerve weakness, which was resolved within 6 months. The radiological investigation showed complete remodeling in 56.2% of the condyles (in the 59 sides, 57 sides were treated by rigid internal fixation and 2 sides were removed the condylar fragments); partial remodeling 27.6% condyles (in the 29 sides, 20 sides were treated by rigid internal fixation and 9 sides were removed the condylar fragments); poor remodeling, 16.2% condyles (in the 17 sides, 2 sides were treated by rigid internal fixation and 15 sides were removed the condylar fragments). CONCLUSIONS Surgical treatment of SFMC is not perfect. There were some complications that occurred after the surgical treatment of SFMC. The findings also indicate that condylar anatomic reduction is the basis for functional recovery and, therefore, rigid fixation should be implemented. Furthermore, the removal of condylar fragments should be performed with caution, and if used, the fragments should be removed entirely.

Abstract
INTRODUCTION The condylar region is a frequent localization of mandibular fractures; there are various types of management. Mini-invasive endoscopic surgery is an alternative to open reduction. We had as goal to evaluate the outcome of this technique. MATERIAL AND METHODS We performed a monocentric retrospective study of patients consecutively operated for a condylar fracture (type II to V in the Spiessl and Schroll classification) with intraoral route and endoscopic assistance, during 30 months. We assessed the functional and radiological outcomes, and the complications. RESULTS Twenty-two patients (25 fractures) were included. Seventeen patients (19 fractures) could be followed (mean follow-up: 16.7 months). The mean values were: interincisal opening, 45mm (±8.4); protrusion, 8.3mm (±1.9); ipsilateral excursion of the jaw: 8.6mm (±2); contralateral excursion: 8.7mm (±4). Three routes were used combined with a preauricular approach. The fracture reduction was good for 10 of the 19 fractures and poor for 3. The complications were: 3 cases of infection, 1 case of fixation failure with good consolidation; for combined approaches: 2 cases of temporary facial palsy and 2 cases of Frey syndrome. DISCUSSION Endoscopic assistance for the surgical management of the fracture of mandibular condyle is a reliable technique, with a good functional outcome, and a low rate of specific complications, especially for facial nerve lesion or esthetic outcome.

Abstract
BACKGROUND Different surgical procedures are utilized for treatment of various diseases of the posterior mandible depending on the type of disease, site, duration and age of the patient. A thorough knowledge of the anatomical relations of structures and adequate surgical skills are needed to minimize complications. The purpose of this study was to evaluate the indications and outcome of surgical techniques for diseases affecting the condyle and ramus of the mandibles. PATIENTS AND METHODS Data were retrieved from the case files of patients who had surgeries for diseases involving the ramus/condylar area of the mandible. The diagnosis/indications for surgery, procedure and postoperative outcomes were documented. Outcomes assessed were related to mouth opening, esthetics (appearance of scar and jaw symmetry) and function (occlusion, Jaw movements). Complications such as nerve dysfunction were documented. Paresthesia was tested by simple tactile stimulations. RESULTS There were a total of 27 procedures done either on the condyle or ramus in 23 (100%) patients between May 2006 and October, 2013. 16 procedures were done for tumors in 16 (69.6%) patients, 14 (60.9%) patients had Ameloblastoma, 1 (4.3%) had central neurofibroma and one had keratocystic odontogenic tumor, two procedures for unilateral condylar fractures in 2 (8.6%) patients, five procedures for ankylosis in 3 (13.0%) patients and four procedures were done for dislocation in 2 (8.6%) patients. There was no permanent nerve dysfunction; mouth opening, jaw movements and mastication were remarkably satisfactory. CONCLUSION Esthetic and functional outcome were quite satisfactory when compared with the preoperative status.

Abstract
The objective of this study was to evaluate any damage to the facial nerve after a retromandibular transparotid approach for open reduction and internal fixation (ORIF) of a subcondylar fracture. We studied 38 patients with 44 subcondylar fractures (3 bilateral and 38 unilateral) treated by ORIF through a retromandibular transparotid approach. All patients were followed up for 6 months. Postoperative function of the facial nerve was evaluated within 24h of operation, and at 1, 3, and 12 weeks, and 6 months. Variables including type of fracture, degree of mouth opening, postoperative occlusion, lateral excursion of the mandible, and aesthetic outcome were also monitored. Nine of the 44 fractures resulted in transient facial nerve palsy (20%). Branches of the facial nerve that were involved were the buccal (n=7), marginal mandibular (n=2), and zygomatic (n=1). In the group with lateral displacement, 2/15 showed signs of weakness, whereas when the fracture was medially displaced or dislocated 7/23 showed signs of weakness. Of the 9 sites affected, 7 had resolved within 3 months, and the remaining 2 resolved within 6 months. The mean (range) time to recovery of function was 12 weeks (3-6 months). There was no case of permanent nerve palsy. The retromandibular transparotid approach to ORIF does not permanently damage the branches of the facial nerve. Temporary palsy, though common, resolves in 3-6 months. Postoperative occlusion, mouth opening, and lateral excursion of the mandible were within the reference ranges. We had no infections, or fractured plates, or hypertrophic or keloid scars.

Abstract
BACKGROUND Fractures of the mandible (lower jaw) are a common occurrence and usually related to interpersonal violence or road traffic accidents. Mandibular fractures may be treated using open (surgical) and closed (non-surgical) techniques. Fracture sites are immobilized with intermaxillary fixation (IMF) or other external or internal devices (i.e. plates and screws) to allow bone healing. Various techniques have been used, however uncertainty exists with respect to the specific indications for each approach. OBJECTIVES The objective of this review is to provide reliable evidence of the effects of any interventions either open (surgical) or closed (non-surgical) that can be used in the management of mandibular fractures, excluding the condyles, in adult patients. SEARCH METHODS We searched the following electronic databases: the Cochrane Oral Health Group's Trials Register (to 28 February 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 1), MEDLINE via OVID (1950 to 28 February 2013), EMBASE via OVID (1980 to 28 February 2013), metaRegister of Controlled Trials (to 7 April 2013), ClinicalTrials.gov (to 7 April 2013) and the WHO International Clinical Trials Registry Platform (to 7 April 2013). The reference lists of all trials identified were checked for further studies. There were no restrictions regarding language or date of publication. SELECTION CRITERIA Randomised controlled trials evaluating the management of mandibular fractures without condylar involvement. Any studies that compared different treatment approaches were included. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed trial quality and extracted data. Results were to be expressed as random-effects models using mean differences for continuous outcomes and risk ratios for dichotomous outcomes with 95% confidence intervals. Heterogeneity was to be investigated to include both clinical and methodological factors. MAIN RESULTS Twelve studies, assessed as high (six) and unclear (six) risk of bias, comprising 689 participants (830 fractures), were included. Interventions examined different plate materials and morphology; use of one or two lag screws; microplate versus miniplate; early and delayed mobilization; eyelet wires versus Rapid IMF™ and the management of angle fractures with intraoral access alone or combined with a transbuccal approach. Patient-oriented outcomes were largely ignored and post-operative pain scores were inadequately reported. Unfortunately, only one or two trials with small sample sizes were conducted for each comparison and outcome. Our results and conclusions should therefore be interpreted with caution. We were able to pool the results for two comparisons assessing one outcome. Pooled data from two studies comparing two miniplates versus one miniplate revealed no significant difference in the risk of post-operative infection of surgical site (risk ratio (RR) 1.32, 95% CI 0.41 to 4.22, P = 0.64, I(2) = 0%). Similarly, no difference in post-operative infection between the use of two 3-dimensional (3D) and standard (2D) miniplates was determined (RR 1.26, 95% CI 0.19 to 8.13, P = 0.81, I(2) = 27%). The included studies involved a small number of participants with a low number of events. AUTHORS' CONCLUSIONS This review illustrates that there is currently inadequate evidence to support the effectiveness of a single approach in the management of mandibular fractures without condylar involvement. The lack of high quality evidence may be explained by clinical diversity, variability in assessment tools used and difficulty in grading outcomes with existing measurement tools. Until high level evidence is available, treatment decisions should continue to be based on the clinician's prior experience and the individual circumstances.

Abstract
In the treatment of mandibular condyle fracture, conservative treatment using closed reduction or surgical treatment using open reduction can be used. Management of mandibular condylar fractures remains a source of ongoing controversy in oral and maxillofacial trauma. For each type of condylar fracture,the treatment method must be chosen taking into consideration the presence of teeth, fracture height, patient'sadaptation, patient's masticatory system, disturbance of occlusal function, and deviation of the mandible. In the past, closed reduction with concomitant active physical therapy conducted after intermaxillary fixation during the recovery period had been mainly used, but in recent years, open treatment of condylar fractures with rigid internal fixation has become more common. The objective of this review was to evaluate the main variables that determine the choice of an open or closed method for treatment of condylar fractures, identifying their indications, advantages, and disadvantages, and to appraise the current evidence regarding the effectiveness of interventions that are used in the management of fractures of the mandibular condyle.
