Kostares E, Kostares M, Kostare G, Kantzanou M. Prevalence of Frey syndrome following extraoral surgical treatment for mandibular fractures: a systematic review and meta-analysis. F1000Res 2023; 12:1153. [PMID: 38106653 PMCID: PMC10721962 DOI: 10.12688/f1000research.140994.2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 11/27/2023] [Indexed: 12/19/2023] Open
Abstract
Our study aims to estimate the prevalence of Frey syndrome following open reduction and internal fixation (ORIF) for mandibular fractures. Two reviewers independently conducted a systematic literature search in the Medline and Scopus databases. The pooled prevalence with 95% confidence intervals (CI) was estimated, and quality assessment, outlier analysis, and influential analysis were performed. In total, fifteen eligible studies were included in this meta-analysis. One study was identified as critically influential. The overall prevalence of Frey syndrome following extraoral surgical treatment for mandibular fractures was estimated as 0.01% (95%CI 0%-0.7%) with moderate heterogeneity observed between studies. In the meta-regression analysis with continuous variables, no statistically significant association was observed. Despite the relatively low prevalence, the impact of Frey syndrome on affected individuals should not be underestimated. Additional research will provide a more comprehensive understanding of the underlying factors contributing to Frey syndrome, leading to improved preventive measures and treatment strategies. A better grasp of the prevalence and associated risk factors will aid in the development of guidelines to minimize the occurrence of this syndrome.

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
To review the literature on the effect of different surgical approaches on facial nerve injuries. The present systematic review addresses the following focus question: Is the facial nerve at risk following surgical correction of mandibular condylar fracture? Electronic and manual literature searches were conducted on databases:PubMed, ScienceDirect and Google scholar,Cochrane and clinicaltrials.gov for studies published until July 2020 to collect information about the effect of different surgical approaches on facial nerve injuries. Systematic literature review was performed following the prisma guidelines to identify studies. Quantitative retrospective and prospective studies,controlled trials,controlled clinical trials were included;case reports and review articles were excluded from this systematic review. 1500 articles published till July 2020 was identified. 116 articles met inclusion criteria. After applying exclusion criteria seven articles were shortlisted. The level of heterogeneity was observed to be less than 50%, between all parameters for all studies making publication bias to be minimum. On comparing various studies statistically using Z-test for all parameters,it was observed that level of significance was significant for various findings like Displacement/Dislocation of fracture and transient facial nerve weakness was found to be statistically significant between all studies (p-value <0.05). Odd ratio, relative ratio and 95% CI was derived for all parameters recorded for various studies. Due to less number of subjective studies, and variability in study designs and lack of reporting on confounding factors,definitive conclusions on effect of various surgical approaches on facial nerve injury cannot be drawn Future well-designed long-term randomized controlled trials are necessary to reveal the necessary correlation between both the parameters.

Abstract
The dilemma regarding the management of condylar fractures generally revolves around the surgical approach, implant design, and the surgeon’s experience. Zide and Kent’s guidelines streamlined the decision making process for condylar fractures. However, there exists no standardized protocol for reduction and fixation of condylar fractures. Here, we have described a detailed and stepwise protocol, common to any surgical approach, that would lead to predictable, reproducible, and repeatable results in every surgeon’s hands.

Three-dimensional assessment of accuracy for open reduction and internal fixation of the subcondylar fracture and its implications on the TMJ function. J Craniomaxillofac Surg 2021; 49:1035-1043. [PMID: 34217568 DOI: 10.1016/j.jcms.2021.06.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 05/24/2021] [Accepted: 06/15/2021] [Indexed: 02/08/2023] Open
Abstract
This study used three-dimensional cone beam computed tomography (CBCT) to assist the accuracy of open reduction and internal fixation (ORIF) for the unilateral subcondylar fracture and the long-term temporomandibular joint (TMJ) function impairment. Bilateral TMJs were analyzed postoperatively on CBCT images, involving the following three-dimensional (3D) parameters: condylar position and inclination; circumferential joint space, ramus, and mandible length; and the volumetric joint space. The inclusion criteria for adult patients included having a displaced fracture >5°, a shortening in ramus length >2 mm, and mouth opening limitation. The non-fracture side was used as the comparison group. The Helkimo index was employed for the clinical assessment of the outcomes, while the paired student t-test and Pearson coefficient test were used to compare both sides. The study included 60 joints in 30 consecutive patients. The condylar inclination to the horizontal plane on the fracture and non-fracture sides was 9.29 ± 3.9°, 12.46 ± 4.2°, (p < 0.001) and was positively related to the subjective (Helkimo Hi) and objective (Helkimo Di) clinical outcomes. In contrast, the condylar position to the midsagittal plane in the fracture and non-fracture sides was 51.95 ± 3.5 mm, 50.17 ± 3.6 mm (P = 0.038), and was positively related to the objective outcomes. Additionally, the objective outcome was negatively related to the change of the posterior joint space. CONCLUSION: The three-dimensional assessments seem to demonstrate that the ORIF is an accurate approach for obtaining a three-dimensional reduction to the displaced subcondylar fracture.

Abstract
Supplemental Digital Content is available in the text. Background: Increasing evidence suggests that open reduction and internal fixation of condylar base fractures in adults results in improved outcomes in regard to interincisal opening, jaw movement, pain, and malocclusion. However, most of the condylar fractures are managed by maxillomandibular fixation alone due to the need for specialized training and equipment. Our aim was to present an algorithm for condylar base fractures to simplify surgical management. Methods: A retrospective review was performed of patients (n = 22) with condylar base fractures treated from 2016 to 2020. Patients who presented with operative fractures that require open treatment underwent 1 of 2 different techniques depending on the fracture type: a preauricular approach with a transoral approach if the condyle was dislocated (n = 2) or a transoral only approach (n = 20) in nondislocated cases. Operative time, occlusion, range of motion, and postoperative complications were assessed. Results: Condylar base fractures were combined with other mandibular fractures in 16 of 22 patients. Patients with condylar dislocation were managed with a preauricular approach with a secondary transoral incision (n = 2, median 147 minutes). Those without dislocation were treated with a transoral approach (n = 20, median 159 minutes). Most patients were restored to their preoperative occlusion without long-term complications. Conclusions: We present a simplified algorithm for treating condylar base fractures. Our case series suggests that reduction in operative time and clinical success can be achieved with open reduction and internal fixation using a transoral approach alone or in combination with a preauricular approach for dislocated fractures.

Abstract
Introduction: The retromandibular transparotid approach is most useful for condylar and subcondylar fractures and provides the best access to the joint and ascending ramus. The study aims at evaluating the ease of access and outcomes encountered on using the retromandibular transparotid approach to access the fracture site for the open reduction and internal fixation (ORIF) of condylar and sub-condylar fractures. Materials and Methods: An observational clinical study was carried out among 10 patients with unilateral and bilateral condylar fracture requiring ORIF. Maximal interincisal mouth opening, facial swelling, occlusal discrepancy, facial nerve injury, scar formation, and acceptability and complications including wound dehiscence, infection, and sialocele/salivary fistula were assessed and measured preoperatively and postoperatively. Results: There was a notable improvement in mouth opening and facial nerve weakness. Postoperative intermaxillary fixation was done with selective patients who had a discrepancy in their occlusion. Preoperatively, swelling was present in four patients (40%) out of 10 patients studied. There was no incidence of sialocele/salivary fistula in any of the cases studied. Conclusion: Retromandibular transparotid incision is technique sensitive and thorough knowledge about the retromandibular area is must for good results and minimal morbidity. The cosmetic results are good in this approach, as well as the facial nerve injury were less in this without any permanent damages.

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
PURPOSE To retrospectively compare the clinical outcomes of closed treatment (closed reduction and intermaxillary fixation) with open treatment (open reduction and internal fixation with miniplates and screws) of unilateral mandibular condylar process fractures. METHODS Adult patients with unilateral condylar fractures treated from January 2011 to July 2013 in the Oral and Maxillofacial Surgery Service at the Base Hospital of the Federal District, Brazil, were invited to participate. Those who agreed to participate were scheduled for clinical evaluation, which consisted of a subjective questionnaire (completed by the examiner) and an objective physical examination of the temporomandibular joints and mandibular range of motion. The following variables were analyzed: mouth opening; lateral excursions of the mandible; presence of clicking; mandibular function impairment (speech, chewing); and occlusion. RESULTS Seventeen patients (15 men and 2 women) attended the scheduled appointment: 9 had received open treatment (surgical) and 8 had received closed treatment (nonsurgical). Patients were evaluated at 6-30 months postoperatively. Only maximum mouth opening (p = 0.044) and maximum lateral excursion to the unaffected side (p = 0.030) showed a significant difference between the closed and open treatment groups. CONCLUSIONS Our findings are consistent with those reported in the literature as both methods (closed and open treatment) produced satisfactory outcomes. The only between-group difference was the amount of maximum mouth opening and lateral excursion to the unaffected side. Further randomized studies with a larger number of patients with condylar process fractures are needed to verify the results obtained with each treatment.

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
BACKGROUND Trismus can be a challenging consequence of ballistic trauma to the face, and has rarely been described in the setting of face transplantation. Almost half of all current face transplant recipients in the world received transplantation to restore form and function after a ballistic injury. Here we report our experience and challenges with long standing trismus after face transplantation. METHODS We reviewed the medical records of our face transplant recipients whose indication was ballistic injury. We focused our review on trismus and assessed the pre-, peri- and postoperative planning, surgery and functional outcomes. RESULTS Two patients received partial face transplantation, including the midface for ballistic trauma. Both patients suffered from impaired mouth opening, speech intelligibility, and oral competence. Severe scarring of the temporomandibular joint (TMJ) required intraoperative release in both patients, and additional total condylectomy on the left side 6 months posttransplant for 1 patient. Posttransplant, both patients achieved an improvement in mouth opening; however, there was persistent trismus. One year after transplantation, range of motion of the jaw had improved for both patients. Independent oral food intake was possible 1 year after surgery, although spillage of liquids and mixed consistency solids persisted. Speech intelligibility testing showed impairments in the immediate postoperative period, with improvement to over 85% for both patients at 1 year posttransplant. CONCLUSIONS Ballistic trauma to the face and subsequent reconstructive measures can cause significant scarring and covert injuries to structures such as the TMJ, resulting in long standing trismus. Meticulous individual planning prior to interventions such as face transplantation must take these into account. We encourage intraoperative evaluation of these structures as well as peri- and postoperative treatment when necessary. Due to the nature of the primary injury, functional outcomes after face transplantation in these patients may differ substantially from those of other indications.

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.

A systematic review and meta-regression analysis. J Craniomaxillofac Surg 2018; 46:1223-1231. [PMID: 29929912 DOI: 10.1016/j.jcms.2018.04.015] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2018] [Revised: 03/20/2018] [Accepted: 04/10/2018] [Indexed: 12/01/2022] Open
Abstract
PURPOSE The purpose of this study was to identify whether the incidence of systematically identified or incidentally encountered facial nerve branches during dissection to approach condylar fractures increases risk of transient and/or permanent facial nerve weakness. METHODS A systematic review and meta-analysis were performed that included several databases with specific keywords, a reference search, and a manual search for suitable articles. The inclusion criteria were all clinical trials, with the aim of assessing the rate of facial nerve injuries when open reduction and internal fixation (ORIF) of condylar process fractures was performed using different surgical approaches. The articles had to have documented the number of encountered facial nerve branches during ORIF. The main outcome variable was transient and permanent facial nerve injury. The dependent variable was the event and/or number of encountered facial nerve branches during surgery, and how they were handled (i.e. dissected, retracted, etc.). RESULTS A total of 1202 mandibular condylar fractures were enrolled in 29 studies. Rate of transient facial nerve injury (TFNI) was 11.3 % (136/1202). The number of facial nerve branches encountered intraoperatively was 543, namely buccal, marginal mandibular, zygomatic and temporal nerve branches. There was a significant correlation suggesting that there is a strong positive linear relationship between TFNI and encountered facial nerve branches (Coef = 0.1916, P = 0.001). There was no significant relationship between permanent facial nerve injury and encountered facial nerve branches (P = 0.808). TFNI was 4.3% and 18.7% for those studies expressly reporting that facial nerve branches were encountered incidentally without dissection and with dissection, respectively. For studies reporting deliberate and systematic facial nerve dissection, TFNI was 20.9%. Finally, studies that did not report any encounters of facial nerve branches, TFNI was 7.9 %. CONCLUSION This meta-analysis demonstrated that manipulation of the facial nerve during different surgical approaches causes different incidences of facial nerve injury. The choice of surgical approach for a given fracture should take this into consideration.

Abstract
Background Craniomaxillofacial (CMF) fractures are typically treated with open reduction and internal fixation. Open reduction and internal fixation can be complicated by hardware exposure or infection. The literature often does not differentiate between these 2 entities; so for this study, we have considered all hardware exposures as hardware infections. Approximately 5% of adults with CMF trauma are thought to develop hardware infections. Management consists of either removing the hardware versus leaving it in situ. The optimal approach has not been investigated. Thus, a systematic review of the literature was undertaken and a resultant evidence-based approach to the treatment and management of CMF hardware infections was devised. Materials and Methods A comprehensive search of journal articles was performed in parallel using MEDLINE, Web of Science, and ScienceDirect electronic databases. Keywords and phrases used were maxillofacial injuries; facial bones; wounds and injuries; fracture fixation, internal; wound infection; and infection. Our search yielded 529 articles. To focus on CMF fractures with hardware infections, the full text of English-language articles was reviewed to identify articles focusing on the evaluation and management of infected hardware in CMF trauma. Each article’s reference list was manually reviewed and citation analysis performed to identify articles missed by the search strategy. There were 259 articles that met the full inclusion criteria and form the basis of this systematic review. The articles were rated based on the level of evidence. There were 81 grade II articles included in the meta-analysis. Result Our meta-analysis revealed that 7503 patients were treated with hardware for CMF fractures in the 81 grade II articles. Hardware infection occurred in 510 (6.8%) of these patients. Of those infections, hardware removal occurred in 264 (51.8%) patients; hardware was left in place in 166 (32.6%) patients; and in 80 (15.6%) cases, there was no report as to hardware management. Finally, our review revealed that there were no reported differences in outcomes between groups. Conclusions Management of CMF hardware infections should be performed in a sequential and consistent manner to optimize outcome. An evidence-based algorithm for management of CMF hardware infections based on this critical review of the literature is presented and discussed.

Abstract
PURPOSE The purpose of this study was to evaluate the rate of complications associated with the retromandibular approach. MATERIALS AND METHODS The design of this research was a retrospective case-series study. Included were patients who 1) underwent open reduction and internal fixation of the condylar or subcondylar area through a retromandibular approach and 2) had a complete and available medical chart. Excluded were 1) patients treated endoscopically or by other approaches and 2) patients with preoperative facial paralysis. The data collected were age, gender, medical comorbidities, tobacco use, mechanism of injury, anatomic location, concomitant facial fractures, follow-up time, antibiotic protocol, and complications. RESULTS One hundred eight patients (81 male; 118 condyles; age, 13 to 82 yr; mean, 35.6 ± 15.8 yr) met the inclusion criteria. Six patients never returned for postoperative visits and the mean follow-up time for all other patients was 6.5 months (8 days to 5.5 years). Twenty-six cases (22%) of temporary paralysis and 1 case of permanent facial paralysis were noted. Eight patients (6.8%) had persistent partial facial paralysis at their last visit, but all had short postoperative follow-ups. Fourteen cases (11.9%) of infection, 4 salivary fistulas, 2 sialoceles, 1 case of Frey syndrome, and 2 seromas were observed. CONCLUSION The retromandibular approach is a safe method for the treatment of condylar process fractures and major complications are rare.

Abstract
We evaluated the safety, efficacy, and morbidity associated with the treatment of displaced mandibular condylar neck fractures using a retromandibular transparotid approach to reduce and rigidly fix using two 2.0-mm locking miniplates. Our surgical inclusion criteria were: patient selection of open reduction and fixation, displaced unilateral condylar fractures with derangement of occlusion, and bilateral condylar fractures with an anterior open bite. The study group consisted of 19 patients who underwent surgery for 19 mandibular condylar neck fractures; patients were analyzed prospectively, with more than 6 months of follow-up, and were evaluated in terms of functional results, scar formation, postoperative complications, and stability of fixation. The results showed that functional occlusion identical to the preoperative condition and correct anatomical reduction of the condylar segments in centric occlusion, followed by immediate functional recovery, was achieved in all patients. No patient suffered from any major or permanent complication postoperatively, although there were two cases (11%) of temporary facial nerve palsy, which resolved completely within 3 months. Surgical scars were barely visible. The retromandibular transparotid approach with open reduction and rigid internal fixation for displaced condylar neck fractures of the mandible is a feasible and safe, minimally invasive surgical technique that provides reliable clinical results.
