There has been an increasing trend in oral squamous cell carcinoma (OSCC) in patients under 45 years of age. The aim of this study was to evaluate the burden of OSCC in the Netherlands between 1989 and 2018 among young adults (age 20 34 years) when compared to adults (age 35-44 years), and to describe the burden in older groups as well, utilizing cancer registry data to characterize incidence patterns by age, sex, and risk factors. A total of 18,963 cases of OSCC were reported. The overall incidence rate, as measured by annual percentage change (APC), increased significantly from 1989 to 2010 by 1.3% per year (95% confidence interval (CI) 0.9-1.7%) but decreased thereafter by -0.9% (95% CI -2.5% to 0.7%). Annual incidence increased significantly by 2.4% (95% CI 1.1-3.8%) for patients aged 20-34 years, while it decreased for those aged 35-44 years by -0.9% (95% CI -1.7% to 0.0%). In patients older than 60 years, incidence rates increased overall (60-74 years: APC 1.8%, 95% CI 1.5-2.1%; >= 75 years: APC 1.5%, 95% CI 1.2-1.9%). Overall, 66.5% of patients were smokers and 65.3% were alcohol consumers. The marked differences in incidence within the young age subgroups warrants further investigation to elucidate any likely disparity in biological process and clinical outcomes in these populations.

This study aimed to analyze the efficacy of stem cell-based tissue engineering for the treatment of alveolar cleft (AC) and cleft palate (CP) defects in animal models. Systematic review and meta-analysis. Preclinical studies on alveolar cleft repair in maxillofacial practice. Electronic search was performed using PubMed, Embase, and Cochrane databases. Pre-clinical studies, where stem cell-based tissue engineering was used in the reconstruction of AC and CP in animal models were included. Quality of the selected articles was evaluated using SYRCLE (SYstematic Review Centre for Laboratory animal Experimentation). Review of alveolar cleft bone augmentation interventions in preclinical models. Outcome parameters registered were new bone formation (NBF) and/or bone mineral density (BMD). Thirteen large and twelve small animal studies on AC (21) and CP (4) reconstructions were included. Studies had an unclear-to-high risk of bias. Bone marrow mesenchymal stem cells were the most widely used cell source. Meta-analyses for AC indicated non-significant benefits in favor of: (1) scaffold + cells over scaffold-only (NBF P = .13); and (2) scaffold + cells over empty control (NBF P = .66; BMD P = .31). Interestingly, dog studies using regenerative grafts showed similar to superior bone formation compared to autografts. Meta analysis for the CP group was not possible. AC and CP reconstructions are enhanced by addition of osteogenic cells to biomaterials. Directions and estimates of treatment effect are useful to predict therapeutic efficacy and guide future clinical trials of bone tissue engineering.

Objective To evaluate the outcomes of Secondary Alveolar Bone Grafting (SABG) in patients treated either in daycare or with multiple day hospitalization (MDH) in relation to costs and complication rates. Design Retrospective comparative cohort study. Setting The data was collected from two settings: Postoperative daycare or MDH after oral cleft surgery in an Academic Medical Center in The Netherlands. Patients Data of 137 patients with unilateral Cleft lip, alveolus, and palate (CLAP) treated between 2006-2018 were evaluated. Registered clinical variables: age, gender, cleft subtype, bone donor site, type of hospitalization, length of stay, additional surgery, complications, surgeons, and costs. Interventions Closure of the alveolar cleft with/without closure of the anterior palate. Main outcome measures Univariate analyses. Results Of the 137 patients, 46.7% were treated in MDH, and 53.3% in daycare. Total costs for daycare were significantly lower ( P Conclusions Daycare after alveolar cleft surgery is about as safe as MDH, but significantly cheaper.

The present study aimed at assessing the epidemiology including demographic variables, diagnostic features, and management of ameloblastomas at several European departments of maxillofacial and oral surgery. The following data were recorded for each patient: gender, age, voluptuary habits, comorbidities, site, size, radiographic features, type, histopathological features, kind of treatment, length of hospital stay, complications, recurrence, management and complications of the recurrence. A total of 244 patients, 134 males and 110 females with ameloblastomas were included in the study. Mean age was 47.4 years. In all, 81% of lesions were found in the mandible, whereas 19% were found in the maxilla. Mean size of included ameloblastomas was 38.9 mm. The most frequently performed treatment option was enucleation plus curettage/peripheral ostectomy in 94 ameloblastomas, followed by segmental resection (60 patients), simple enucleation (46 patients), and marginal resection (40 patients). A recurrence (with a mean follow up of 5 years) was observed in 47 cases out of 244 ameloblastomas (19.3%). Segmental resection was associated with a low risk of recurrence (p = 0003), whereas enucleation plus curettage/peripheral ostectomy was associated with a high risk of recurrence (p = 0002). A multilocular radiographic appearance was associated with a high risk of recurrence (p < .05), as well as the benign solid/multicystic histologic type (p < .05). Within the limitations of the study it seems that the management of ameloblastomas will probably remain controversial even in the future. Balancing low surgical morbidity with a low recurrence rate is a difficult aim to reach.

Objectives: In this cadaveric study, the accuracy of CAS guided mandibular and maxillary reconstruction including immediate dental implant placement in different Brown defect classes is assessed. Materials and methods: The virtual planning and surgical procedure was conducted according to a newly proposed Amsterdam UMC reconstruction protocol. Postoperative evaluation was performed according to a previously proposed evaluation guideline. Results: Fourteen mandibular and 6 maxillary reconstructions were performed. Average mandibular angle deviations were 1.52°±1.32, 1.85°±1.58, 1.37°±1.09, 1.78°±1.37, 2.43°±1.52 and 2.83°±2.37, respectively for the left and right axial angles, left and right coronal angles and left and right sagittal angles. A total of 62 dental implants were placed in neomandibles with an average dXYZ values of 3.68 ± 2.21 mm and 16 in neomaxillas with an average dXYZ values of 3.24 ± 1.7 mm. Conclusion: Promising levels of accuracy were achieved for all mandibular angles. Dental implant positions approached the preoperative preferred positions well, within the margin to manufacture prosthetic devices.

INTRODUCTION: Odontoma is the most commonly diagnosed odontogenic tumor of the oral cavity. The objective of the present study was to assess the demographic variables, patterns, diagnostic features, and management issues of odontomas treated at several European departments of maxillofacial and oral surgery.MATERIALS AND METHODS: This study was conducted at 8 European departments of oral surgery between January 1, 2004, and December 31, 2018. Only patients with odontomas were included. The following data were recorded for each patient: gender, age, comorbidities, site, size of odontomas, radiographic features, type of odontoma, treatment of odontomas, treatment of associated teeth, complications, and recurrence.RESULTS: A total of 127 patients (70 male and 57 female patients) with odontomas were included. The mean age was 22 years; 71 odontomas were found in the mandible, whereas 56 in the maxilla. In the mandible, the most frequently involved subsite was the parasymphysis, while in the maxilla, the most common subsite was the upper incisor region. The mean size of included odontomas was 15.3 mm. On the whole, 62 complex odontomas, 50 compound odontomas, and 15 mixed-type odontomas were observed. Complete excision of the odontomas was performed in 121 patients. In 24 patients, the extraction of deciduous teeth was performed, and in 43 patients, one or more permanent teeth were removed. Finally, in 9 patients, a partial excision of the odontoma was performed. Recurrence was observed in 4 cases out of 127 patients.CONCLUSIONS: Dental practitioners should be aware of the distinct clinical and radiographic features of odontoma in order to perform an appropriate and early diagnosis. Conventional radiography, such as panoramic radiograph, is often sufficient technique for a diagnosis after clinical suspicion or for an incidental diagnosis to prevent later complications, such as impaction or failure of eruption of teeth.

The objective of the present study was to assess the epidemiology including demographic variables, diagnostic features, and the management of odontogenic keratocyst (OKCs) at several European departments of maxillofacial and oral surgery. This study is based on a systematic computer-assisted database that allowed the recording of data from treated OKCs. The following data were recorded for each patient: gender, age, voluptuary habits, comorbidities, site, size, radiographic features, treatment of OKCs, length of hospital stay, complications, recurrence, management and complications of eventual recurrence. A total of 405 patients, 249 male and 156 female, with 415 OKCs (407 sporadic and 8 syndromic lesions) were included in the study: 320 lesions were found in the mandible, whereas 95 were found in the maxilla. In the mandible, the most frequently involved subsite was the angle, whereas in the maxilla it was the molar region. The most frequently performed treatment option was enucleation plus curettage/peripheral ostectomy in 204 OKCs (recurrence rate, 9%). Decompression without residual cystectomy (recurrence rate, 66%), marsupialization with residual enucleation with the use of Carnoy's solution (recurrence rate, 50%), decompression with residual cystectomy (recurrence rate, 43%), and simple enucleation (recurrence rate, 24%) were the treatment options with the highest recurrence rates. An appropriate management of odontogenic keratocysts should be individualized, taking into consideration clinical and radiological findings, as well as patients’ age and comorbidities.

INTRODUCTION: The aim of the present article was to review and depict the main radiological features of odontogenic keratocysts (OKCs), thus helping the differential diagnoses from other odontogenic cysts and neoplasms. EVIDENCE ACQUISITION: A review of articles published between January 2000 and October 2020 using Medline and the MeSH Term "odontogenic keratocyst" in combination with the following terms "imaging," "radiology," "panoramic radiograph," and "computed tomography," was performed. EVIDENCE SYNTHESIS: Radiographically, OKCs are well-defined unilocular or multilocular radiolucencies bounded by corticated margins. Most lesions are unilocular; instead, multilocular OKCs represent about the 30% of cases, mainly involving the posterior mandible. When, particularly in large lesions, OKCs display a multilocular presentation with adjacent satellite cysts (daughter cysts) a "soap-bubble appearance" can be recognized. DISCUSSION: Panoramic radiograph and CT still play an important role in the diagnosis and treatment planning of OKCs. Unfortunately, it may not be easy to differentiate OKCs from other odontogenic lesions, especially when they are small and unilocular. CONCLUSIONS: Histopathological findings are still necessary to obtain a definitive diagnosis.

© 2021 The Author(s)The study aimed at evaluating, comprehensively, implant-based dental rehabilitation in head and neck cancer patients after maxillofacial reconstruction with a vascularized free fibula flap (FFF). Data were obtained by retrospectively reviewing the medical records of patients treated in Amsterdam UMC-VU Medical Center. Dental implant survival and implant success according to the Albrektsson criteria were analyzed. Additionally, prosthetic-related outcomes were studied, with a focus on functional dental rehabilitation. In total, 161 implants were placed in FFFs, with a mean follow-up of 4.9 years (range 0.2–23.4). Implant survival was 55.3% in irradiated FFFs and 96% in non-irradiated FFFs. Significant predictors for implant failure were tobacco use and irradiation of the FFF. Implant success was 40.4% in irradiated FFFs and 61.4% in non-irradiated FFFs, mainly due to implant failure and non-functional implants. Implant-based dental rehabilitation was started 45 times in 42 patients, out of 161 FFF reconstructions (27.9%). Thirty-seven patients completed the dental rehabilitation, 29 of whom achieved functional rehabilitation. Irradiation of the FFF negatively influenced attainment of functional rehabilitation. For patients with functional rehabilitation, the body mass index varied at different timepoints: FFF reconstruction, 24.6; dental implantation 23.5; and after placing dental prosthesis, 23.9. Functional implant-based dental rehabilitation, if started, can be achieved in the majority of head and neck cancer patients after FFF reconstruction. Actively smoking patients with an irradiated FFF should be clearly informed about the increased risk for implant and prosthetic treatment failure.

Objectives The purpose of this European multicenter prospective study was to obtain more precise information about the demographic characteristics and etiologic/epidemiologic patterns of motor vehicle accidents (MVA)–related maxillofacial fractures. Study Design Of the 3260 patients with maxillofacial fractures admitted within the study period, 326 traumas were caused by MVAs with a male/female ratio of 2.2:1. Results The maximum incidence was found in Zagreb (Croatia) (18%) and the minimum in Bergen (Norway) (0%). The most frequent mechanisms were car accidents, with 177 cases, followed by motorcycle accidents. The most frequently observed fracture involved the mandible, with 199 fractures, followed by maxillo-zygomatic-orbital (MZO) fractures. Conclusions In all the 3 groups (car, motorcycle, and pedestrian), mandibular and MZO fractures were the 2 most frequently observed fractures, with some variations. The importance of analyzing MVA-related facial injuries and their features and characteristics should be stressed.

The aim of this study was to analyse the effect of body mass index (BMI), both low and high values, on the perioperative complication rate in patients with oral squamous cell carcinoma (OSCC). The medical records of 259 patients operated between 2014 and 2017 for OSCC were reviewed. Univariate and multivariate analyses were performed. Sixty of the 259 patients developed 87 complications. Low or high BMI was not associated with the perioperative complication rate. A longer operating time and increased blood loss were associated with a higher perioperative complication rate and higher Clavien–Dindo grade. Low BMI, American Society of Anesthesiologists score 2 and 3, a longer operating time, and increased blood loss were associated with a longer hospital stay. Low BMI was associated with a longer hospital stay. Neither low nor high BMI was associated with the perioperative complication rate. A longer operating time and increased blood loss were associated with a higher perioperative complication rate and higher Clavien–Dindo grade.

Background/aims: When facial trauma involves elderly patients, the possible presence of frailty and comorbidities in victims of trauma may worsen the posttraumatic symptoms and decrease quality of life. The aim of this multicenter study was to assess the quality of life following surgical or non-operative management of maxillofacial trauma in elderly patients. Materials and methods: This cohort study was based on the administration of validated self-administered questionnaires to all the geriatric patients (70 years or more) with facial fractures from the involved maxillofacial surgical units across Europe, since 1st January 2019 to 31st June 2019. The following questionnaires were administered: SF36 questionnaire; the VFQ-25 questionnaire; the Oral Health Impact Profile – 14 (OHIP14). Outcome variables were VFQ-25 and OHIP-14 results. Results: A total of 37 patients (14 male and 23 female patients) met the inclusion criteria and were included in the study. Elderly patients had an improvement in almost all the categories examined by the SF-36 questionnaire 6 months after trauma, with the only exception of a worsening as for role limitations due to physical health. An improvement was observed in almost all the categories at SF-36 test. A worsening of scores of OHIP-14 for all the considered dimensions in the whole study population was observed too. Conclusions: Elderly patients following facial trauma experience significant emotional, social, and functional disturbances. We observed that emotional problems, energy/fatigue, social functioning, and generally social limitations played a great role in the decrease of QoL in elderly patients following maxillofacial trauma.

OBJECTIVES: Patients with inflammatory bowel disease have an increased risk of developing oral health problems. The aim of this study was to investigate whether oral diseases in these patients are related to inflammation of the intestine and if there is a correlation between inflammatory bowel disease-specific health-related quality of life (IBD-HR-QOL) and oral health problems.STUDY DESIGN: The study was a cross-sectional survey and analysis of self-reported oral health of individuals with a stoma for Crohn's disease (CD), ulcerative colitis (UC), and treated colon cancer (CC). Validated international questionnaires were sent to members of the Stoma Federation of The Netherlands. Because there was an unequal distribution of male and female patients with CD and CC, data of 169 age-matched female patients with CD, UC, and CC with a stoma were analyzed.RESULTS: Patients with CD had significantly more oral health problems compared with those with UC or CC. Patients with CD and UC both had significantly more gingival-related problems compared with patients with CC. There was a significant negative correlation between IBD-HR-QOL and oral health problems.CONCLUSIONS: In the 3 distinguishable groups of patients with a stoma, patients with CD had an increased risk for oral health problems, independently from surgical removal of (a part of) the inflamed intestine, suggesting a general increased susceptibility of patients with CD for oral health problems.

Background/Aims Management of maxillofacial trauma in the geriatric population poses a great challenge due to anatomical variations and medical comorbidities. The aim of this study was to analyze the management variables, timing, and outcomes of facial fractures in elderly patients (aged 70 years or more) at several European departments of oral and maxillofacial surgery. Materials and Methods This study was based on a systematic computer-assisted database that allowed the recording of data from all geriatric patients with facial fractures from the involved maxillofacial surgical units across Europe between 2013 and 2017. Results A total of 1334 patients were included in the study: 665 patients underwent closed or open surgical treatment. A significant association (P lt .005) was found between the presence of concomitant injuries and a prolonged time between hospital admission and treatment. The absence of indications to treatment was associated with comorbidities and an older age (P lt .000005). Conclusions Elderly patients require specific attention and multidisciplinary collaboration in the diagnosis and sequencing of trauma treatment. A prudent attitude may be kept in selected cases, especially when severe comorbidities are associated and function is not impaired., Peer-reviewed manuscript: [http://smile.stomf.bg.ac.rs/handle/123456789/2528]

INTRODUCTION: Management of body fractures in patients with edentulous atrophic mandibles represents a challenging task due to patient's age, medical comorbidities, poor bone quality, and vascularity, as well as reduced contact area between the fracture ends. The aim of the study was to assess the demographic and clinical variables, the surgical technique, and outcomes of unilateral body fractures of the edentulous atrophic mandible managed at several European departments of oral and maxillofacial surgery.METHODS: This study is based on a systematic computer-assisted database that allowed the recording of data of all patients with fractures of the atrophic edentulous mandible from the involved maxillofacial surgical units across Europe between 2008 and 2017. The following data were recorded for each patient: gender, age, comorbidities, etiology, synchronous body injuries, degree of atrophy of the mandible according to Luhr classification, type of surgical approach and fixation, length of hospitalization, and presence and type of complications.RESULTS: A total of 43 patients were included in the study: 17 patients' mandibles were classified as class I according to Luhr, 15 as class II, and 11 as class III. All patients underwent open reduction and internal fixation by extraoral approach in 25 patients, intraoral in 15 patients, and mixed in 3 patients. A single 2.0 miniplate was used in 16 patients, followed by a single 2.4 reconstruction plate in 13 patients, by two 2.0 miniplates, and three 2.0 miniplates. Outcome was considered to be satisfying in 30 patients, with no complications. Complications were observed in 13 cases.CONCLUSIONS: Treatment of unilateral body fractures of the edentulous mandible must still be based on the type of fracture, degree of atrophy, experience of the surgeon, and patients' preference. An adequate stability can be obtained by different plating techniques that have to be appropriately tailored to every single specific patient.

Background The buccal fat pad (BFP) is an encapsulated mass originated from a specific fat tissue in various volume throughout the life of each person and BFP has been used in various surgeries as a source of useful graft material due to its easy accessibility and rich vascularization. Case Report This report describes fifteen patients who were treated with buccal fat pads (BFP) as a pedicled graft for lateral relaxing wound closure in primary cleft palate surgery. A review of relevant literature is also presented. Results All patients had a mean follow-up of 3.7 weeks with a minimum follow-up time of three weeks and a maximum follow-up of four weeks. All patients who had an uneventful immediate postoperative period showed signs of BFP epithelialization characterized by a yellowish tissue beginning in the first week and ending within 3–4 weeks after surgery. Conclusions The use of BFP for the small to medium-sized defects reconstruction in palatoplasty is a safe and reliable method with fast healing. Even older patients who would not be able to tolerate time-consuming flap reconstruction procedures had good results. Key words:Cleft palate, buccal fat pads, lateral relaxing wound.

Purpose: Recent literature suggests that sialendoscopy of the major salivary glands could alleviate symptoms of Sjögren syndrome (SS) and restore salivary function. The aim of this study was to evaluate the authors’ experience of sialendoscopy of the salivary glands in patients with SS. Materials and Methods: In this retrospective case series study, the surgical data of patients with SS who had undergone sialendoscopy at the VU University Medical Center (Amsterdam, The Netherlands) from November 2014 through April 2015 were used. Outcome measurements were successful entry to the salivary gland and completion of sialendoscopy as planned. Furthermore, pre- and postoperative complications were scored. Descriptive analysis of the data was performed. Results: Surgical data of sialoendoscopic procedures in 26 patients with SS (24 women and 2 men; mean age, 57 yr; range, 27 to 72 yr) were analyzed. Sialendoscopy was successfully performed in 78 of 104 salivary glands (75%; 50 parotid and 28 submandibular glands) in the 26 patients. Sialendoscopy failed in 26 of the 104 sialoendoscopic procedures (25%; 2 parotid and 24 submandibular glands). In 16 salivary glands, the ductal orifice could not be identified. In 7 salivary glands, sialendoscopy could not be performed because of partial or complete stenosis of the salivary duct. In 3 salivary glands, sialendoscopy was not performed because of a ductal perforation. Three patients developed a postoperative infection. Conclusion: The overall rate of complications was limited and the sialoendoscopic complications in patients with SS could be regarded as minor. Most complications were seen for sialendoscopy of the submandibular glands in this specific patient category. Careful preoperative selection of patients and salivary glands could contribute to a lower rate of complications and more predictable results.

INTRODUCTION: The objective of the present study was to assess the demographic variables, causes, and patterns of edentulous atrophic fractures of the mandible managed at several European departments of oral and maxillofacial surgery. The results of this multicenter collaboration over a 10-year period are presented.METHODS: The data of all patients with fractures of the atrophic edentulous mandible from the involved maxillofacial surgical units across Europe between January 1, 2008, and December 31, 2017 were recorded: gender; age; voluptuary habits; comorbidities; etiology; fracture sites; synchronous body injuries; atrophy of the mandible according to Luhr classification; eventual type of treatment; timing of the eventual surgery; length of hospital stay.RESULTS: A total of 197 patients (86 male and 111 female patients) with 285 mandibular fractures were included in the study. Mean age of the study population was 75 years. Statistically significant associations were found between Luhr classes I - II and condylar fractures on one hand (p < .0005), and between Luhr class III and body and parasymphyseal fractures on the other hand (p < .05). Finally, 135 patients underwent open reduction and internal fixation, 56 patients did not undergo any intervention, and 6 patients underwent closed reduction. No statistically significant association was observed between treatment, timing of treatment, comorbidities, and concomitant injuries.CONCLUSIONS: The management of edentulous atrophic mandibular fractures remains challenging. Treatment decisions should continue to be based on the clinician's previous experience and on the degree of bone resorption in edentulous mandible in relation to fracture subsites.

Objective: The aim of this study was to analyze the complications and outcomes of surgical treatment of angle fractures managed at departments of maxillofacial surgery in several European countries. Study Design: Patients hospitalized with unilateral isolated angle fractures between 2013 and 2017 were included. The following data were recorded: gender and age of patients, fracture etiology, presence of the third molar, maxillomandibular fixation, osteosynthesis technique, and complications. Results: In total, 489 patients were included in the study. The Champy technique was found to be the most frequently chosen osteosynthesis technique. Sixty complications were observed, at a rate of 12.3%. Complications were associated with the absence of third molars (P < .05). Instead, the Champy technique was associated with fewer complications (P < .05), in comparison with the other adopted techniques. Conclusions: The management of angle fractures still represents a challenging task with a significant complication rate. The Champy technique still seems to be a valid option for the treatment of such injuries.

Purpose: Fractures of the zygomaticomaxillary complex (ZMC) are common injuries that may lead to loss of an aesthetically pleasing appearance and functional impairment. The aim of this study was to analyze the demographics, causes, characteristics, and outcomes of zygomatic fractures managed at several European departments of oral and maxillofacial surgery. Materials and methods: This study is based on a multicenter systematic database that allowed the recording of all patients with ZMC fractures between 1 January 2013 and 31 December 2017. The following data were recorded: gender, age, personal medical history, etiology, side of zygomatic fracture, classification of ZMC fracture, associated maxillofacial fractures, symptoms at diagnosis, type of performed treatment, and sequelae/complications. Results: A total of 1406 patients (1172 males, 234 females) were included in the study. Statistically significant correlations were found between assault-related ZMC fractures and the A3 class (p

INTRODUCTION: The progressive aging of European population seems to determine a change in the epidemiology, incidence and etiology of maxillofacial fractures with an increase in the frequency of old patients sustaining craniofacial trauma. The objective of the present study was to assess the demographic variables, causes, and patterns of facial fractures in elderly population (with 70 years or more).MATERIALS AND METHODS: The data from all geriatric patients (70 years or more) with facial fractures between January 1, 2013, and December 31, 2017, were collected. The following data were recorded for each patient: gender, age, voluptuary habits, comorbidities, etiology, site of facial fractures, synchronous body injuries, Facial Injury Severity Score (FISS).RESULTS: A total of 1334 patients (599 male and 735 female patients) were included in the study. Mean age was 79.3 years, and 66% of patients reported one or more comorbidities. The most frequent cause of injury was fall and zygomatic fractures were the most frequently observed injuries. Falls were associated with a low FISS value (PCONCLUSIONS: This study confirms the role of falls in the epidemiology of facial trauma in the elderly, but also highlights the frequency of involvement of females, and the high frequency of zygomatic fractures.

Purpose: The aim of this study was to analyze the demographic variables and causes and characteristics of mandibular angle fractures managed at several European departments of maxillofacial surgery. Materials and Methods: This study was based on a multicenter systematic database that allowed the recording of data from all patients with mandibular angle fractures between January 1, 2013, and December 31, 2017. The following data were recorded: gender, age, etiology, side of angle fracture, associated mandibular fractures, presence of third molar, intermaxillary fixation, and osteosynthesis. Results: The study included 1,162 patients (1,045 male and 117 female patients). A significant association was found between the presence of a third molar and the diagnosis of an isolated angle fracture (P

Objective: Surgical resection remains the primary treatment for the majority of solid tumors. Despite efforts to obtain wide margins, close or positive surgical margins (

Comparing accuracy results for mandibular reconstructions using computer-assisted surgery (CAS) is limited due to heterogeneity in image acquisition, extent of mandibular resection, and evaluation methodologies between studies. We propose a practical, feasible and reproducible guideline for standardizing evaluation methods to allow valid comparisons of postoperative results and facilitate meta-analyses in the future. It offers a guide to imaging, data comparison, volume assessment of 3-dimensional models, classification of defects, and it also contains a quantitative accuracy evaluation method.

OBJECTIVE: This retrospective study evaluated survival rates, prognosis, and overall success of autotransplanted teeth in young patients missing anterior teeth as a result of trauma, agenesis, or developmental disturbances.STUDY DESIGN: Retrospective data were collected from the medical records of patients who had undergone tooth autotransplantations to anterior sites between January 2001 and December 2012. Clinical variables, such as gender, age, surgical indications, donor and recipient sites, type of anesthetics, bone augmentation, and complications during follow-up, were assessed.RESULTS: A total of 59 donor teeth in 46 patients (30 boys and 16 girls; average age 12.15 years) were autotransplanted to the anterior region of the maxilla and mandible. After a mean follow-up period of 17.35 months (range 10-61 months), all of the transplanted teeth remained in situ with no complications.CONCLUSIONS: This study supports the autotransplantation of teeth to the anterior alveolus as a viable option suitable in growing patients with missing anterior teeth.

Purpose: Oral soft tissue augmentation or grafting procedures are often necessary to achieve proper wound closure after deficits resulting from tumor excision, clefts, trauma, dental implants, and tooth recessions.Materials and Methods: Autologous soft tissue grafts still remain the gold standard to acquire a functionally adequate zone of keratinized attached gingiva. However, soft tissue substitutes are more commonly used because they minimize morbidity and shorten surgical time.Results: This review aimed to assess soft tissue grafting techniques and materials used in the oral cavity from existing literature. There are a large variety of materials and techniques, including grafts, local flaps, allogenic derived matrices such as acellular dermal allograft, xenogenic tissue matrices from animal origin, and synthetic materials.Conclusions: Tissue engineering of oral mucosa represents an interesting alternative to obtain sufficient autologous tissue for reconstructing oral wounds using biodegradable scaffolds, and may improve vascularization and epithelialization, which are critical for successful outcomes.

Computer-assisted surgery (CAS) for mandibular reconstruction was developed to improve conventional treatment methods. In the past years, many different software programs have entered the market, offering numerous approaches for preoperative planning and postoperative evaluation of the CAS process of mandibular reconstruction. In this systematic review, we reviewed planning and evaluation methods in studies that quantitatively assessed accuracy of mandibular reconstruction performed with CAS. We included 42 studies describing 413 mandibular reconstructions planned and evaluated using CAS. The commonest software was Proplan/Surgicase CMF (55%). In most cases, the postoperative virtual 3-dimensional model was compared to the preoperative 3-dimensional model, revised to the virtual plan (64%). The commonest landmark for accuracy measurements was the condyle (54%). Accuracy deviations ranged between 0 mm and 12.5 mm and between 0.9° and 17.5°. Because of a lack of uniformity in planning (e.g., image acquisition, mandibular resection size) and evaluation methodologies, the ability to compare postoperative outcomes was limited; meta-analysis was not performed. A practical and simple guideline for standardizing planning and evaluation methods needs to be considered to allow valid comparisons of postoperative results and facilitate meta-analysis in the future.

The purpose of this study was to analyse the demographics, causes and characteristics of maxillofacial fractures managed at several European departments of oral and maxillofacial surgery over one year. The following data were recorded: gender, age, aetiology, site of facial fractures, facial injury severity score, timing of intervention, length of hospital stay. Data for a total of 3396 patients (2655 males and 741 females) with 4155 fractures were recorded. The mean age differed from country to country, ranging between 29.9 and 43.9 years. Overall, the most frequent cause of injury was assault, which accounted for the injuries of 1309 patients; assaults and falls alternated as the most important aetiological factor in the various centres.The most frequently observed fracture involved the mandible with 1743 fractures, followed by orbital-zygomatic-maxillary (OZM) fractures. Condylar fractures were the most commonly observed mandibular fracture.The results of the EURMAT collaboration confirm the changing trend in maxillofacial trauma epidemiology in Europe, with trauma cases caused by assaults and falls now outnumbering those due to road traffic accidents.The progressive ageing of the European population, in addition to strict road and work legislation may have been responsible for this change. Men are still the most frequent victims of maxillofacial injuries.

ObjectiveArch bars as treatment for a fractured mandibular condyle are inconvenient to patients and lead to lowered quality of life (QOL). To overcome these inconveniences, IMF-screws (IMFS) to facilitate intermaxillary fixation during surgery have been developed. The purpose of the present study is to investigate and compare QOL for patients treated for a fractured mandibular condyle with either IMFS or arch bars.Material and methodsThis research trial was conducted from 2010 to 2014 as part of an earlier prospective, multicenter, randomized clinical trial in which the use of IMFS was compared to the use of arch bars in the treatment of mandibular condylar fractures.ResultsIn total, 50 patients were included: 30 (60%) male patients and 20 (40%) female patients (mean age: 31.8 years, standard deviation [SD] = 13.9 years, range = 18-64years). A total of 24 (48%) patients were allocated in the IMFS group, and 26 (52%) patients were assigned to the arch-bars control group. Significant results were observed in the subscales social isolation, possibility to eat and vary diet, influence on sleep, and satisfaction with the given treatment, all in favour of IMFS.ConclusionIn conclusion, using IMFS as a method for conservative treatment of condylar fractures led to a higher QOL during the 6-week period of fracture healing. In comparison to arch bars, patients treated with IMFS experienced less social isolation, had fewer problems with eating, and express the feeling they are able to continue their normal diet. Furthermore it seems that the use of IMFS has a lower negative impact on social and financial aspects of the patient.

The aim of the present study was to assess the indications, results and complications of patients treated with porous polyethylene (Medpor®) implants in the Department of Oral and Maxillofacial Surgery of VU Medical Centre, Amsterdam over 17 years. A total of 69 high-density porous polyethylene implants (Medpor® Biomaterial; Porex Surgical, Newman, GA) were used in forty patients (22 males, 18 females). All patients were analysed for gender, age, diagnosis, indications for surgery, follow-up period and postoperative complications. A mean age of 34.1 years was observed. The main reason for implant surgery was post-traumatic functional impairment (27.5%). Most implants were placed at the mandibular angel and the orbital floor. Unsatisfactory appearance scored the highest in postoperative complications (10.1%) followed by infection rate (7.2%). Comparing the number of implants placed over the years and the incidence of complications, makes the overall complications rate of porous polyethylene very low. A consensus about antibiotic prophylaxis is needed. The objective measurements in patient satisfaction and proper implant design would be of great use.

Objectives: The aim of this study was to evaluate the treatment of mandibular fractures treated in two European centre in 10 years. Study Design: This study is based on 2 systematic computer-assisted databases that have continuously recorded patients hospitalized with maxillofacial fractures in two centers in Turin, Italy and in Amsterdam, the Netherlands for ten years. Only patients who were admitted for mandibular fractures were considered for this study. Results: Between 2001 and 2010, a total of 752 patients were admitted at Turin hospital with a total of 1167 mandibular fractures not associated with further maxillofacial fractures, whereas 245 patients were admitted at Amsterdam hospital with a total of 434 mandibular fractures. At Amsterdam center, a total of 457 plates (1.5 - 2.7 mm) were used for the 434 mandibular fracture lines, whereas at Turin center 1232 plates (1.5 – 2.5 mm) were used for the management of the 1167 mandibular fracture lines. At Turin center, 190 patients were treated primarily with IMF, whereas 35 patients were treated with such treatment option at Amsterdam center. Conclusions: Current protocols for the management of mandibular fractures are quite efficient. It is difficult to obtain a uniform protocol, because of the difference of course of each occurring fracture and because of surgeons’ experiences and preferences. Several techniques can still be used for each peculiar fracture of the mandible.

We retrospectively analysed the incidence of symptomatic venous thromboembolism (VTE) and associated risk factors in operations under general anaesthesia for cancer of the oral cavity. To identify symptoms related to deep venous thrombosis (DVT) and pulmonary embolism (PE), together with associated risk factors, we reviewed medical records of patients operated on in the department of oral and maxillofacial surgery at the Queen Elizabeth Hospital, Birmingham, United Kingdom, between June 2007 and October 2012. All patients were categorised according to their level of risk of VTE. The incidence of VTE was calculated with univariate associations and odds ratios with related 95% confidence intervals, where possible. In total, 233 patients were included, comprising 244 operations (mean (SD) age at operation 60.9 (13) years). Almost all patients (97%) were classified as having the highest risk of VTE. Swelling of an extremity, expectoration of blood, and tightness of the chest were the most common symptoms for suspected cases. An incidence of 0.41% was found for symptomatic VTE; one man developed a PE 2 days after operation. Associations between the analysed factors and symptomatic VTE were not significant. The development of the complication in oncological oral and maxillofacial operations seems to be rare, even in patients with a high risk. We cannot recommend the use of routine thromboprophylaxis, but it could be advocated in patients with obvious serious risk factors.

AimThe aim of this study was to retrospectively investigate the incidence and associated factors of dental trauma in patients with maxillofacial fractures at the VU Medical Center in Amsterdam.Material and methodsData from 707 patients who were treated surgically for maxillofacial fractures were evaluated. The data were collected retrospectively from patient files and other available databases. The data collected included date of fracture, age, gender, type of fracture, and injured teeth.ResultOf the total 707 patients, 164 patients (23.2%) presented dental injuries associated with facial fractures. Mandibular condylar fractures, mandibular parasymphyseal fractures, Le Fort fractures, and mandibular body fractures were found to be significantly more associated with dental injury. Zygomatic arch or zygomatic complex fractures were significantly less associated with dental injury. Women had a significant higher risk of facial fractures with dental injuries than men. The maxilla demonstrated the highest incidence of injured teeth. The most affected teeth were the maxillary incisors (33.1%), followed by mandible incisors (13.6%), mandible molars (12.8%), and maxillary premolars (12.6%).ConclusionOur findings show a higher risk of dental injury among patients with a mandibular condylar fracture and mandibular parasymphyseal fracture but a lower risk of dental injury among patients with a zygomatic arch or zygomatic complex fracture. On average, patients had more than three injured teeth, with most of the injured teeth being in the upper jaw. The maxillary incisors, followed by the mandible incisors, were the most injured teeth.

Background To investigate retrospectively the orthognathic surgery (OGS) patients experience in weight loss and the influence of gender, age, duration of the surgical procedure, length of hospital stay, location of surgery and use of intermaxillary fixation (IMF) or without IMF on postoperative weight loss. Material and Methods A total of 4487 patients treated by OGS where all patients visited the outpatient clinic one, three and six weeks after the surgical procedure. After six weeks, patients filled out a questionnaire in which weight loss was addressed. The patients were asked to give an estimate of their experiences weight loss. The population was first divided in two groups weight loss and no weight loss. Results In the weight loss group there is no significant difference in weight loss between patients with IMF and patients without IMF. In the weight loss group there were significantly more females then males. Further, in the subgroup IMF the operation time was significantly longer compared with the subgroup without IMF. The other parameters including age and hospital stay were not different in the groups. Conclusions IMF in orthognathic treatment does not result in a difference self-reported loss of body weight compared to patients without IMF. Treatment protocols should include pre- and post-operative dietician consultations and possible indications for medical nutrition and vitamins. Key words:Assessing, protocol, weight loss, experiences, orthognathic surgery.

Venous thromboembolism is a common postoperative complication, and orthopaedic procedures are particularly at risk. We designed a retrospective, single centre, observational, cohort study of 4127 patients (mean (SD) age 27 (11) years) who had elective orthognathic operations or distraction osteogenesis between January 1970 and February 2012 at the VU University Medical Centre, Amsterdam, to investigate the incidence in this group over the 42-year period, 2 patients developed symptomatic venous thromboembolism (1 woman had a deep vein thrombosis (DVT) and 1 man had a DVT and pulmonary embolus) postoperatively. In relatively young patients with low to moderate risk factors and short hospital stay this type of operation is associated with a particularly low risk of developing thrombosis. It could be advisable to limit the use of thromboprophylaxis to patients at high risk or according to hospital guidelines.

Several studies have published measurements of the height of the ramus on orthopantomographic (OPT) images of patients with unilateral fractures of the mandibular condyle as a possible quantitative measure for making decisions about treatment. However, we know of no studies that have described the accuracy and validity of such measurements. The aim of the present study was to assess the shortening of the ramus in patients with such fractures, and compare them with differences found in a control group. Seventy-four patients and 74 controls were studied. The height of the ramus on the fractured was less than that on the uninjured side, although this was not statistically significant (p = 0.25). In the control group, 50 subjects (68%) had a difference in the ramal height of more than 2 mm. Of 74 patients, 25 (34%) had a shorter, uninjured ramus on the opposite side. A Bland and Altman scatterplot showed 23 outliers (31%) among the patients, which exceeded the mean (SD 1.96) of the control group. The interobserver and intraobserver reliability both showed excellent agreement for all measurements made. Shortening of the ramus can be measured on OPT images. However, in a control group there was a large mean difference in height. Among the patients, 25/74 (34%) also had an uninjured ramus on the opposite side that was shorter than that on the fractured side. Measurement of the difference in height on an OPT image cannot be relied on as an absolute indication for intervention.

The aim of this study was to assess the characteristics of patients with coronoid fractures treated in two European centres over 10 years and to briefly review the literature.This study is based on 2 systematic computer-assisted databases that have continuously recorded patients hospitalized with maxillofacial fractures and surgically treated in two European centres between 2001 and 2010.During the 10 years, 1818 patients and 523 patients with maxillofacial fractures were admitted to the two centres respectively: 21 patients (16 males, 5 females) were admitted with 21 coronoid fractures and 28 associated maxillofacial fractures.A mean age of 42.1 years was observed. The fractures were mainly the result of motor vehicle accidents, followed by assaults and falls. The most frequently observed associated maxillofacial fracture was a zygomatic fracture (13 fractures). In both centres, mandibular coronoid fractures are treated unless a severe dislocation of the fractured coronoid is observed or a functional mandibular impairment is encountered.Conservative treatment can be used, together with the open reduction and internal fixation of associated fractures. The crucial point is to prevent ankylosis, which may be prevented by correct and early postoperative physiotherapy and mandibular function.

Maxillofacial trauma is often associated with injuries to the cranium, especially in high-energy trauma. The management of such cases can be challenging and requires close cooperation between oral and maxillofacial surgery and neurosurgical teams. There are few reports in the current literature describing the complications that develop in patients with maxillofacial trauma and traumatic brain injury (TBI). Complications can be categorized as early or late and/or minor and major. The exact definition of complications and their categorization remains a matter of current debate. We present a 10 year retrospective study of complications and their subsequent management in patients receiving maxillofacial and neurosurgical treatment for maxillofacial trauma associated with TBI. The study population consisted of 47 people, excluded from a maxillofacial trauma population of 579 patients. The severity of the trauma was scored as mild, moderate or severe, using the Glasgow Coma Scale at presentation of the Emergency Department. In total 36 patients (76.6%) developed complications. Patients involved in road traffic collision were most likely to develop complications (92.3%). This was followed by falls (66.7%) as mechanism of the injury. Patients aged 60-69 years experienced the highest complication rate (5), followed by patients aged 20-29 years (4.1) and 30-39 years (3.5). The majority of complications were infection and inflammation (36.4%), followed by neurological deficit (24.0%), physiological dysregulation (11.6%) and facial bone deformity (8.3%). Patients who developed no complications, most often presented with mild TBI (72.7%).The most common treatment modality employed to manage complications was pharmacological, followed by antibiotic treatment, conservative treatment and decompression therapy. The mean hospital stay after the trauma for the patients with complications was 28 days. Thirteen patients (36.1%) were transferred to a rehabilitation centre, a nursing home, or a home for the elderly. Nine patients (25%) completely recovered from their complications and 4 patients (11.1%) died after the trauma. This report provides useful data concerning the rate and type of complications that occur, and the multidisciplinary treatment that is required in traumatic maxillofacial and brain injury patients.

BackgroundThe aim of this study was to evaluate the surgical management of posttraumatic dysocclusion in the Department of Oral and Maxillofacial Surgery in the VU Medical Centre in Amsterdam.Patients and methodsAll patients who underwent surgical correction of a posttraumatic dysocclusion between 1970 and 2012 were reviewed. Patient charts were reviewed retrospectively.ResultsA total of 42 patients were included. Twenty-seven patients had a mandibular condyle fracture (64.3%). The initial fracture-treatment was either conservative, consisting only of intermaxillary fixation (IMF), or open reduction and internal fixation (ORIF). Though different orthognathic treatment options were used to regain normal occlusion, the most frequently used surgical techniques were a uni- or bilateral sagittal split osteotomy of the mandible in 21 patients (50.0%), followed by a Le Fort I osteotomy of the maxilla in 17 patients (40.5%).ConclusionsMost dysocclusions occur after mandibular condyle fractures, however fractures of other maxillofacial structures also account for a considerable number of cases. Good results are achieved with orthognathic surgery for posttraumatic dysocclusion.

The aim of the study was to investigate the incidence of the inferior alveolar nerve (IAN) injury in mandibular fractures. This study is based on two databases that have continuously recorded patients hospitalized with maxillofacial fractures in two departments—Department of Maxillofacial Surgery, Vrije Universiteit University Medical Center, Amsterdam, the Netherlands, and Division of Maxillofacial Surgery, San Giovanni Battista Hospital, Turin, Italy. Demographic, anatomic, and etiology variables were considered for each patient and statistically assessed in relation to the neurosensory IAN impairment. Statistically significant associations were found between IAN injury and fracture displacement ( p = 0.03), isolated mandibular fractures ( p = 0.01), and angle fractures ( p = 0.004). A statistically significant association was also found between IAN injury and assaults ( p = 0.03). Displaced isolated mandibular angle fractures could be considered at risk for increased incidence of IAN injury. Assaults seem to be the most important etiological factor that is responsible for IAN lesions.

The risk of bias is important in the interpretation of the results of research. The aim of this review was to evaluate the risk of bias in randomised controlled trials (RCTs) in oral and maxillofacial surgery (OMFS) over a 10-year period. We searched databases of publications for RCTs published between January 2000 and January 2010. Papers were assessed with 2 up-to-date logical quality lists, the Delphi list and the Jadad scale. Those papers with a low risk of bias were given a Jadad score >= 4 (range 0-5) and a Delphi score >= 6 (range 0-9). A total of 230 papers met the inclusion criteria, and only 41(18%) were assessed as being at low risk. Most of those included did not correctly describe such important items for risk of bias as method of randomisation (n = 124, 54%), concealment of allocation (n = 143, 62%), blinding (n = 175, 76%), and intention-to-treat analyses (n = 182, 79%). In the fields of implantology, traumatology, obstructive sleep apnoea syndrome, and extractions, no paper had a low risk of bias. This systematic review has shown a shortage of research in OMFS with a low risk of bias published over a 10-year period. Further research should concentrate on better describing items at important risk of bias. (C) 2013 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

The influence of funding on the main outcome of a random control trial (RCT) is important, as it could potentially lead to bias towards industry, and results that are too optimistic. We investigated the association between funding, the published outcome, and the risk of bias in trials in oral and maxillofacial surgery (OMFS) published from January 2000 to May 2013 listed in PubMed. The methods used were scored using the risk of bias items given in a Delphi List. Sources of funding were recorded and categorised five ways: not funded, funded by industry, not funded by industry, supported by industry, and source of funds not clear. A total of 390 RCT met the inclusion criteria, and there was a correlation between funding and favourable main outcomes, although this was not significant. There was no correlation between the risk of bias and favourable results of the main outcome of a trial, or between the risk of bias and the reported source of funding in post-hoc analysis. We were unable to show a significant correlation between funding and a higher likelihood of a favourable result for the primary outcome in RCT in OMFS. We also failed to show a significant correlation between the risk of bias of a trial and its main outcome. In contrast, the source of funding proved to affect the risk of bias of a trial significantly, although not in post-hoc analysis. Funded trials were better organised, and so had a lower risk of bias.

Introduction: The incidence of maxillofacial fractures varies widely between different countries. The large variability in reported incidence and aetiology is due to a variety of contributing factors, including environmental, cultural and socioeconomic factors. This retrospective report presents a study investigating the aetiology and incidence of patients with maxillofacial fractures in Amsterdam over a period of 10 years. Results: The study population consisted of 408 males and 171 females with a mean age of 35.9 (SD: ±16.3) years. The age group 20-29 years accounted for the largest subgroup in both sexes. The most common cause of the fractures was traffic related, followed by violence. There were mainly mandibular and zygomatic bone fractures in both males and females, accounting for approximately 80% of all fractures. The main fracture site of the mandible was the combination of mandibular body with mandibular condyle (66 patients; 26.8%), followed by the combination of bilateral condylar fracture and fracture of the symphysis (43 patients; 17.5%). In fractures of the upper 2/3 of the face, zygomatic bone fractures were most common. In patients with alcohol consumption the injury was mostly the result of violence. In conclusion, this report provides important data for the design of plans for injury prevention, as compared with previous studies. Violence related injuries are increasing whereas fractures caused by traffic accidents are decreasing. © 2011 European Association for Cranio-Maxillo-Facial Surgery.

This study was designed to investigate retrospectively the incidence of venous thromboembolism (VTE) and the need for thromboembolism prophylaxis in patients undergoing surgery for oral and maxillofacial trauma. Data were obtained from all patients treated under general anaesthesia for maxillofacial trauma between January 2000 and January 2009 in the Department of Oral and Maxillofacial Surgery of the VU University Medical Center, Amsterdam. Patients' records were reviewed for complaints and information related to deep venous thrombosis (DVT) and pulmonary embolism (PE). The patients were classified according to a risk classification, and the incidence of reported DVT and PE was calculated. None of the patients received any form of thromboembolism prophylaxis. Of the 479 patients included in this study, one presented with VTE (0.2%). This male patient was treated for a panfacial trauma and was classified as high risk. From all analysed parameters only surgery time classification proved to have a significant relationship with VTE. © 2012 International Association of Oral and Maxillofacial Surgeons.

The surgical treatment and complications of patients with mandibular fractures in Amsterdam over a period of 10 years are analysed. Between January 2000 and January 2009 225 patients were surgically treated for a mandibular fracture (mean age of 32.6 (SD ± 14.6) years). A total of 426 fracture lines were identified. Of 213 dentate patients 29 patients were treated primarily with intermaxillary fixation (IMF). IMF combined with osteosynthesis was performed on 99 patients. Seventy-nine patients received IMF only per-operatively to make open reduction and internal fixation (ORIF) possible. Of 12 edentulous patients three patients were treated with Gunning splints. Nine patients were treated by manual reduction and internal fixation. A total of 1965 screws and 442 plates were used. Sixty (26.7%) patients presented with complications, including (transient) hyposensibility of the lip and chin (34 patients), dysocclusion (15 patients), infected osteosynthesis material (six patients) and temporomandibular dysfunction (five patients). Four patients needed surgical retreatment for correction of a dysocclusion. The results of this report are partly in line with other studies and provide important data for improving the treatment of the fractured mandible. © 2011 European Association for Cranio-Maxillo-Facial Surgery.

Objective. Controversy exists about the effectiveness of anticonvulsants for the management of orofacial pain disorders. To ascertain appropriate therapies, a systematic review was conducted of existing randomized controlled trials.Study design. Trials were identified from PubMed, Cochrane, and Ovid Medline databases from 1962 through March 2010, from references in retrieved reports, and from references in review articles. Eight useful trials were identified for this review. Six studies were randomized placebo-controlled trials and 2 studies were randomized active-controlled. Two independent investigators reviewed these articles by using a 15-item checklist.Results. Four studies were classified as "high quality." However, heterogeneity of the trials and the small sample sizes precluded the drawing of firm conclusions about the efficacy of the interventions studied on orofacial pain patients. Conclusions. There is limited to moderate evidence supporting the efficacy of commonly used anticonvulsants for treatment of patients with orofacial pain disorders. More randomized controlled trials are needed on the efficacy of anticonvulsants.
