Treatment of tophaceous pseudogout in the temporomandibular joint with resection and alloplastic reconstruction: a single-staged approach.

Tophaceous pseudogout is a rare variant of the calcium pyrophosphate dihydrate (CPPD) disorder, with predilection for the TMJ. It is characterized by calcific deposits composed of rhomboid- or rectangular-shaped crystals that exhibit birefringence when examined under polarized light. We hereby present a case of a 65-year-old man with left pre-auricular tenderness and malocclusion. CT imaging was notable for a left TMJ mineralized mass with erosion of the condylar head. Treatment involved excision of the mass with eminectomy, condylectomy, and a stock total TMJ reconstruction. In this report, important considerations for diagnosis, biopsy, and surgical treatment with emphasis on reconstruction for tophaceous pseudogout of the TMJ have been highlighted by the authors.

A Multidisciplinary Approach and Review of Safety Recommendations for Plastic Surgeons during the COVID-19 Pandemic: Are N95 Masks Enough?

SUMMARY: The novel coronavirus disease of 2019 pandemic presents a unique challenge to the field of plastic and reconstructive surgery. Although plastic surgeons may be postponing elective operations, there are still a number of emergent or urgent procedures that may need to be performed, and surgeons may be facing the reality of returning to a new normalcy of operating with coronavirus disease of 2019. These procedures, consisting of those such as head and neck reconstruction or maxillofacial trauma, largely require a multidisciplinary approach and may be considered of higher risk to health care workers because of the involvement of areas of the body identified as sources for viral transmission. Moreover, viral transmission may potentially extend beyond respiratory secretions, which has been the main focus of most safety precautions. The authors aim to present the scope of these procedures and the means of viral transmission, and to provide safety precaution recommendations for plastic surgery and its related disciplines.

A survey assessing the early effects of COVID-19 pandemic on oral and maxillofacial surgery training programs.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic has specific implications for oral and maxillofacial surgeons because of an increased risk of exposure to the virus during surgical procedures involving the aerodigestive tract. The objective of this survey was to evaluate how the COVID-19 pandemic affected oral and maxillofacial surgery (OMFS) training programs during the early phase of the pandemic. STUDY DESIGN: During the period April 3 to May 6, 2020, a cross-sectional survey was sent to the program directors of 95 of the 101 accredited OMFS training programs in the United States. The 35-question survey, designed by using Qualtrics software, aimed to elicit information about the impact of the COVID-19 pandemic on OMFS residency programs and the resulting specific modifications made to clinical care, PPE, and resident training/wellness. RESULTS: The survey response rate from OMFS program directors was 35% (33 of 95), with most responses from the states with a high incidence of COVID-19. All OMFS programs (100%) implemented guidelines to suspend elective and nonurgent surgical procedures and limited ambulatory clinic visits by third week of March, with the average date being March 16, 2020 (date range March 8-23). The programs used telemedicine (40%) and modified in-person visit (51%) protocols for dental and maxillofacial emergency triage to minimize the risk of exposure of HCP to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Shortage of personal protective equipment (PPE) was experienced by 51% of the programs. Almost two-thirds (63%) of the respondents recommended the use of a filtered respirator (i.e., N95 respirator) with full-face shield and stated that it was their preferred PPE, whereas 21% recommended the use of powered air-purifying respirators (PAPRs) during OMFS procedures. Only (73%) of the programs had resources for resident wellness and stress reduction. Virtual didactic training sessions conducted on digital platforms, most commonly Zoom, formed a major part of education for all programs. CONCLUSIONS: All programs promptly responded to the pandemic by making appropriate changes, including suspending elective surgery and limiting patient care to emergent and urgent services. OMFS training programs should give more consideration to providing residents with adequate stress reduction resources to maintain their well-being and training and to minimize exposure risk during an evolving global epidemic.

Considerations for Oral and Maxillofacial Surgeons in COVID-19 Era: Can We Sustain the Solutions to Keep Our Patients and Healthcare Personnel Safe?

Several uncertainties exist regarding how we will conduct our clinical, didactic, business, and social activities as the coronavirus disease 2019 (COVID-19) global pandemic abates and social distancing guidelines are relaxed. We anticipate changes in how we interact with our patients and other providers, how patient workflow is designed, the methods used to conduct our teaching sessions, and how we perform procedures in different clinical settings. The objective of the present report is to review some of the changes to consider in the clinical and academic oral and maxillofacial surgery workflow and, allow for a smoother transition, with less risk to our patients and healthcare personnel. New infection control policies should be strictly enforced and monitored in all clinical and nonclinical settings, with an overall goal to decrease the risk of exposure and transmission. Screening for COVID-19 symptoms, testing when indicated, and establishing the epidemiologic linkage will be crucial to containing and preventing new COVID-19 cases until a vaccine or an alternate solution is available. Additionally, the shortage of essential supplies such as drugs and personal protective equipment, the design and ventilation of workspaces and waiting areas, the increase in overhead costs, and the possible absence of staff, if quarantine is necessary, must be considered. This shift in our workflow and patient care paths will likely continue in the short-term at least through 2021 or the next 12 to 24 months. Thus, we must prioritize surgery, balancing patient preferences and healthcare personnel risks. We have an opportunity now to make changes and embrace telemedicine and other collaborative virtual platforms for teaching and clinical care. It is crucial that we maintain COVID-19 awareness, proper surveillance in our microenvironments, good clinical judgment, and ethical values to continue to deliver high-quality, economical, and accessible patient care.

Maxillomandibular Advancement Improves Multiple Health-Related and Functional Outcomes in Patients With Obstructive Sleep Apnea: A Multicenter Study.

PURPOSE: To comprehensively determine the effectiveness and safety of maxillomandibular advancement (MMA) for the treatment of obstructive sleep apnea (OSA). PATIENTS AND METHODS: We designed and implemented a prospective multicenter cohort study to evaluate OSA patients who underwent MMA. The primary outcome measures and associated instruments included sleepiness (Epworth Sleepiness Scale [ESS]), quality of life (QOL) (Functional Outcomes of Sleep Questionnaire [FOSQ]), sleep-disordered breathing (apnea-hypopnea index), cardiovascular risk (office blood pressure and levels of high-sensitivity C-reactive protein), and neurocognitive performance (psychomotor vigilance testing [PVT]). The outcomes were measured preoperatively and approximately 6 months postoperatively. Other variables were grouped into the following categories: demographic and pre-MMA use of continuous positive airway pressure. Descriptive and bivariate statistics were computed. RESULTS: The sample was composed of 30 adult patients (63% men; mean age, 45.9 ± 9.8 years). The median length of follow-up was 6.7 months (range, 4.3 to 12.7 months). The ESS score decreased from a mean of 13.3 to 4.9 (P < .001). The FOSQ score increased from a mean of 14.1 to 18.3 (P < .001). The apnea-hypopnea index decreased from a mean of 39.6 to 7.9 events per hour (P < .001). Mean diastolic blood pressure decreased from 83 to 79.7 mm Hg (P = .025). PVT response times improved after MMA (P = .04). Few treatment-related adverse events occurred, which had minimal impact on the QOL. Additional improvements in sleepiness (mean ESS score change, -7.6; P < .001), QOL (mean FOSQ score change, 3.9; P < .001), and PVT (mean change, 0.5; P = .004) occurred after MMA for patients using continuous positive airway pressure before surgery. CONCLUSIONS: MMA is a highly effective and safe treatment for OSA, which predictably leads to significant improvements in sleepiness, QOL, sleep-disordered breathing, and neurocognitive performance, as well as a reduction in cardiovascular risk (blood pressure).

A Novel Mobile Health Approach to Early Diagnosis of Oral Cancer.

AIM: The incidence of oral cancer is high in India, which can be reduced by early detection. We aimed to empower frontline health care providers (FHP) for early detection and connect specialist to rural population through mHealth. MATERIALS AND METHODS: We provided training to FHPs in examination of oral cavity, use of mobile phone for image capture, and risk factor analysis. The FHPs were selected from different cohorts in resource-constrained settings. The workflow involved screening of high-risk individuals in door-to-door and workplace settings, and capture of images of suspected lesions. Uploaded data were interpreted and recommendation was sent by specialist from a remote location. Their recommendation was intimated to FHPs who arranged for further action. Two more initiatives, one for multiple dental schools and another for private practitioners, were undertaken. RESULTS: During the period from 2010 to 2018, 42,754 subjects have been screened, and 5,406 subjects with potentially malignant disorders have been identified. The prevalence of potentially malignant disorders varied from 0.8 to 62% at different cohorts; 516 biopsies have been performed at remote locations. CONCLUSION: Connecting specialists to rural population was made possible through the use of mobile health. Trained FHP were able to reach out to the population. Electronic data capture facilitated efficient follow-up. The program was very cost-effective with screening completed under $1 per person. CLINICAL SIGNIFICANCE: In view of the high incidence of oral cancer in India, and the resource-constrained settings, mobile health paves the way for better access to specialist care for the rural population.

Surgical Management of Idiopathic Condylar Resorption: Orthognathic Surgery Versus Temporomandibular Total Joint Replacement.

Young females with retruded and hyperdivergent mandibles, class II openbite malocclusions, and steep occlusal planes with or without TMJ symptoms are at higher risk for Idiopathic Condylar Resorption (ICR). Such patients undergoing orthodontic and /or surgical treatment should be informed of possible relapse due to ICR. Orthognathic Surgery with Total joint replacement or Orthognathic surgery alone may both be acceptable options for management of the facial deformity and the malocclusion that ensues from ICR. Proper patient selection is key to achieving a successful outcome. Current trends and the evidence in the literature suggest that orthognathic surgery with alloplastic joint replacement may be the preferred approach.

Postoperative Pain and Opioid Analgesic Requirements After Orthognathic Surgery.

PURPOSE: The purpose of this study was to determine the effect of individual characteristics, such as age, gender, and type of surgery, on postoperative pain intensity and opioid analgesic consumption after orthognathic surgery. PATIENTS AND METHODS: This prospective observational study was conducted at a single academic medical center during a 12-month period from 2015 to 2016. Thirty of 125 patients 18 to 65 years of age who had American Society of Anesthesiologists status I and II and were admitted to the hospital after orthognathic surgery were recruited. The main outcome variable was opioid analgesic consumption measured in morphine milligram equivalents (MME) during the patients' hospital stay. Secondary outcome variables were postoperative pain intensity measured using the numeric rating scale (0 to 10) and length of hospital stay. Data on age, gender, type of surgery, postoperative pain intensity, and opioid and nonopioid analgesic consumption for each 24-hour period during hospitalization were collected. The analgesic regimen consisted of oxycodone, hydromorphone, and acetaminophen. Differences in postoperative pain and opioid requirements between men and women, older and younger, and 1- and 2-jaw surgery were assessed using unpaired Student t test for statistical analysis. A P value less than .05 was considered statistically significant. RESULTS: Thirty patients (14 men, 16 women) with an average age of 26.3 years (18 to 50 yr) were admitted to the hospital for an average of 61 hours (24 to 170 hours) after orthognathic surgery. Twenty-three of 30 patients (77%) had bimaxillary surgery. The average postoperative pain score was 6.0 (2 to 8.5) on a scale of 0 to 10 and average opioid consumption was 106 MME (range, 0 to 407 MME). Women reported more postoperative pain (6.3 vs 5.3) and consumed more opioid analgesic than men (131 vs 78 MME). Patients younger than 25 years required 112 MME of opioid compared with 98 MME for those older than 25 years, although the 2 age groups reported similar pain scores. Patients who had 2-jaw surgery and mandibular (1-jaw) surgery reported more pain and required more opioid analgesics than those who had only maxillary surgery. CONCLUSION: Based on these study results, there appears to be a trend for increased opioid analgesic requirement in women and younger patients during the immediate postoperative period after orthognathic surgery.

Is Alloplastic Temporomandibular Joint Reconstruction a Viable Option in the Surgical Management of Adult Patients With Idiopathic Condylar Resorption?

PURPOSE: Idiopathic condylar resorption (ICR) presents diagnostic and therapeutic challenges to practitioners because of the rarity of the condition, progressive deformity, and simultaneous involvement of skeletal, occlusal, and articular disorders. The objective of this study was to report clinical outcomes after prosthetic replacement of the temporomandibular joint (TMJ) for the management of ICR. PATIENTS AND METHODS: A retrospective analysis of patients with ICR managed by bilateral total TMJ replacement and concomitant mandibular advancement with or without maxillary surgery was performed using data gathered from medical records. The primary treatment outcomes of interest were 1) correction of anterior open bite malocclusion, 2) mandibular advancement, and 3) increase in posterior facial height. Secondary outcomes included subjective assessment of pain, dietary restrictions, and functional disability and objective evaluations of TMJ sounds, occlusal relation, mandibular range of motion, cranial nerve VII injury, and objectionable scarring. Radiographs were used to measure surgical change and relapse. RESULTS: Twenty-one patients met the inclusion criteria for this retrospective study. The average patient age was 25.6 years (range, 22 to 32 yr) and mean follow-up was 6.2 years (range, 5 to 12 yr). Mean mandibular advancement at the B point was 24.3 mm and mean change in occlusal plane was -10.2°. Sixteen patients (76%) underwent maxillary orthognathic surgery for posterior downgrafting with rigid fixation and grafting. Long-term follow-up showed excellent stability of surgical movements with a decrease in TMJ and myofascial pain, headaches, and dietary restrictions. CONCLUSIONS: Patients with ICR can be effectively treated using total TMJ prostheses with maxillary orthognathic surgery when indicated for the correction of an associated dentofacial deformity. Use of alloplastic joint prostheses allows for the execution of large mandibular advancements in a predictable and accurate manner with a meaningful decrease in symptoms of TMJ dysfunction.

Treatment Algorithm for Intracranial Intrusion Injuries of the Mandibular Condyle.

PURPOSE: Traumatic injuries of the mandible resulting in intrusion of the condyle into the middle cranial fossa are rare and treatment is often based on anecdotal experience. The objective of this study was to develop an algorithm for the management of condylar intrusion injuries by identifying factors that influenced the treatment decision of closed versus open reduction of the condyle. MATERIALS AND METHODS: This study was a systematic review of the literature on intracranial intrusion injuries of the mandibular condyle. A thorough search of the PubMed and Cochrane databases and individual maxillofacial and craniofacial journal databases was conducted using the Medical Subject Heading terms condylar impaction, condylar dislocation, condylar intrusion, and middle cranial fossa and condyle without date and language restriction. Quantitative data on the patient's age, gender, etiology of injury, and time from injury to diagnosis were analyzed using descriptive statistics. The authors studied how the predictor variables of age, etiology, time from injury to diagnosis, and associated neurologic injuries influenced the outcome variable of closed versus open reduction of the condyle. RESULTS: Forty-eight of the 62 retrieved case reports, case series, and review articles were published in the English-language literature from 1963 to 2015. Data on 51 patients with these injuries showed that 38 (75%) were female and younger than 30 years. The most common etiology of injury was motor vehicular accidents, occurring in 25 of 51 patients (49%). The mean time from injury to diagnosis was 31.2 days (0 to 106.4 days). Forty of the 51 patients (78%) were diagnosed within the first 2 weeks of injury. A good proportion of patients underwent open reduction (63%) and 18 of the 51 of patients (35%) underwent closed reduction. CONCLUSIONS: Predictor variables that influenced the treatment decision of open versus closed reduction were age of the patient, etiology of injury, and time from injury to diagnosis. Based on the present results, younger patients (0 to 15 yr old), patients who sustain condylar intrusion injuries from bicycle accidents, and those diagnosed within the first 2 weeks of injury are more likely to benefit from closed reduction. The treatment algorithm emphasizes the importance of assessment of associated neurologic injuries and an interdisciplinary approach for the management of these injuries.

Mobile health application for remote oral cancer surveillance.

BACKGROUND: To determine the effectiveness of a mobile phone-based remote oral cancer surveillance program (Oncogrid) connecting primary care dental practitioners and frontline health care workers (FHW) with oral cancer specialists. METHODS: The study population (N = 3,440) included a targeted cohort (n = 2,000) and an opportunistic cohort (n = 1,440) screened by FHW and dental professionals, respectively. The authors compared the screening efficacy in both groups, with specialist diagnosis considered the reference standard. The outcomes measured were lesion detection and capture of interpretable images of the oral cavity. RESULTS: In the targeted cohort, among 51 of 81 (61%) interpretable images, 23 of 51 (45%) of the lesions were confirmed by specialists, while the opportunistic cohort showed 100% concordance with the specialists (106 of 106). Sixty-two of 129 (48%) of the recommended patients underwent biopsy; 1 of 23 (4%) were in the targeted cohort, and 61 of 106 (57%) were in the opportunistic cohort. Ninety percent of the lesions were confirmed to be malignant or potentially malignant. CONCLUSIONS: The mobile health-based approach adopted in this study aided remote early detection of oral cancer by primary care dental practitioners in a resource-constrained setting. Further optimization of this program is required to adopt the system for FHW. Evaluation of its efficacy in a larger population is also warranted. PRACTICAL IMPLICATIONS: The increased efficiency of early detection by dentists, when assisted by a remote mobile health-based approach, is a step toward a more effective oral cancer screening program.

Quality of life after maxillectomy and prosthetic obturator rehabilitation.

PURPOSE: Surgical resection of midface neoplasms and subsequent reconstruction have been shown to have significant negative effects on quality of life (QOL). The purpose of this pilot study was to assess individuals' health-related QOL after maxillectomy and reconstruction with a prosthetic obturator. MATERIALS AND METHODS: The QOL of 25 of 43 patients who underwent maxillectomy and prosthetic obturator reconstruction at the University of California-San Francisco was assessed using 3 questionnaires: University of Washington Quality of Life version 4 (UWQOL), Obturator Functioning Scale (OFS), and Mental Health Inventory (MHI). RESULTS: The response rate to the QOL questionnaires was 92% (23 of 25 patients). Time elapsed from maxillectomy and prosthetic obturator reconstruction to the QOL survey response ranged from 0.3 to 6.6 years (mean, 2.7 years; standard deviation [SD], 1.9 years). The post-treatment mean QOL scores were 77.3 (SD, 13.6) for UWQOL, 72.0 (SD, 12.6) for OFS, and 4.5 (SD, 0.9) for Mental Health Inventory. Individuals who received adjuvant radiation scored lower for speech and appearance (OFS, P = .05, P = .03, respectively) as well as for saliva and overall QOL (UWQOL, P = .02, P = .08, respectively). There was a strong correlation between QOL scores in OFS and UWQOL questionnaires (r = 0.78, P < .001). CONCLUSION: The results of this pilot study suggest that postoperative radiation therapy was the strongest variable affecting QOL in patients with maxillectomy and prosthetic obturator reconstruction. There is further need for a multicenter trial with a larger sample to identify how factors affecting QOL of patients after maxillectomy might influence the choice of reconstruction.

Frequency of surgical correction for maxillary hypoplasia in cleft lip and palate.

OBJECTIVE: The aim of this study was to determine the frequency of surgical correction of maxillary hypoplasia in individuals with nonsyndromic cleft lip and/or palate (CL/P) treated at the Center for Craniofacial Anomalies at University of California, San Francisco (UCSF). SUBJECTS: This is a retrospective cohort study of individuals with cleft lip and/or palate born between 1970 and 1990 who were treated at the UCSF Center for Craniofacial Anomalies. Data were gathered from the UCSF Craniofacial Anomalies Filemaker Pro database. METHODS: From the database, we collected the following information: age, gender, cleft type, date of orthognathic surgery, and type of osteotomy. The subjects were further subcategorized by cleft type and gender. RESULTS: A total of 973 individuals with a diagnosis of cleft lip and/or palate were reviewed: 325 subjects had an associated syndrome and 648 were nonsyndromic. A total of 59 of these 648 nonsyndromic cleft individuals (9.1%) required surgical intervention for correction of maxillary hypoplasia: 2/105 (1.9%) for cleft lip, 4/122 (3.3%) for cleft palate, 35/286 (12.2%) for unilateral cleft lip and palate, and 18/135 (13.3%) for bilateral cleft lip and palate. CONCLUSIONS: The frequency of surgical correction for maxillary hypoplasia in cleft individuals at UCSF Center for Craniofacial Anomalies at 9% was lower than the reported average of 25%.

20q- clonality in a case of oral sweet syndrome and myelodysplasia.

We report the case of a patient with myelodysplasia who had Sweet syndrome of the oral cavity. An atypical myeloid immunophenotype was present in the gingival biopsy specimen and in a concurrent bone marrow specimen. Fluorescence in situ hybridization performed on the gingival biopsy specimen demonstrated the same del(20q) cytogenetic abnormality present in the bone marrow, confirming the presence of a clonally related myeloid proliferation in both tissues. This is the first reported case of Sweet syndrome and myelodysplasia in which the chromosomal abnormality was identified in the neutrophilic infiltrate, confirming the neutrophilic infiltrate to be clonally related to the underlying myeloid neoplasm.

Three-dimensional assessment of the eruption path of the canine in individuals with bone-grafted alveolar clefts using cone beam computed tomography.

OBJECTIVE: To evaluate the eruption path of the permanent maxillary canine during a 1-year period after secondary alveolar bone grafting and to (1) compare the canine eruption path on the cleft and noncleft side, (2) examine the number of congenially missing lateral incisors and the rate of canine impaction, and (3) examine the relationship between the eruption status of the canine and timing of alveolar bone grafting relative to age and canine root development using cone beam computed tomography (CBCT). METHODS: Cone beam computed tomography scans for 17 nonsyndromic unilateral cleft lip and palate (UCLP), and four bilateral cleft lip and palate (BCLP) consecutive cases of alveolar bone grafting surgery were obtained after orthodontic expansion and before alveolar bone grafting and at least 1 year postsurgery on the Hitachi MercuRay CBCT machine. The DICOM files were imported into Dolphin 3D Imaging 10.5 and reoriented for consistency. The X, Y, and Z coordinates were determined for the canine cusp tip and root tip on both the cleft and noncleft sides. The direction of movement of the canine in 1 year was determined. RESULTS: Most canines on both the cleft and noncleft sides moved incisally, facially, and mesially. Twelve percent of the canines on the cleft side appeared to require surgical exposure. Eighty percent of the canines had less than half root development at the time of bone grafting. The amount of root development did not affect the outcome in terms of eruption amount or direction. CONCLUSIONS: Most canines on both the cleft and noncleft side moved incisally, facially, and mesially.

Morphologic and management characteristics of individuals with unilateral cleft lip and palate who required maxillary advancement.

OBJECTIVE: To delineate factors that may contribute to maxillary hypoplasia requiring maxillary advancement surgery in individuals with nonsyndromic unilateral cleft lip and palate (UCLP). METHODS: This retrospective, longitudinal study used lateral cephalometric radiographs and chart reviews of 16 nonsyndromic UCLP individuals who underwent Le Fort I maxillary advancement and 16 controls matched for cleft type, age, and gender. Cephalometric measurements were made at three time points (T1, T2, and T3): mean ages of 10.7, 13.3, and 15.8 years for the Le Fort group and 10.11, 12.9, and 15.7 years, respectively, for the control group. Information regarding team care, timing and number of surgical procedures, and number of congenitally missing teeth were determined from clinical records. RESULTS: The Le Fort group had significant maxillary hypoplasia at all time points compared to the UCLP controls, indicated by midface length measurements, ANB and Wit's analysis (p < .001). The Le Fort group had twice the number of palatal surgical procedures and number of missing teeth in the maxillary arch as compared with the cleft controls. Most of the control group had consistent team care, while most of the surgical group did not. CONCLUSIONS: Maxillary hypoplasia that will require a Le Fort I advancement can be determined as early as age 10. Multiple missing maxillary teeth, secondary palate procedures including pharyngeal flaps, and inconsistent team care with delayed orthodontic intervention are contributing factors to maxillary underdevelopment.

Orthognathic surgery for secondary cleft and craniofacial deformities.

Orthognathic surgery is a critical component of surgical management of craniofacial deformities such as cleft lip and palate, craniofacial dysostoses, and mandibulofacial dysostoses. These operations can correct discrepancy in jaw relationship and malocclusion, relieve airway obstruction, correct facial asymmetry, optimize facial aesthetics, improve speech articulation, improve ability to masticate, and enhance psychological development and social interaction. Oral and maxillofacial surgeons who treat these deformities should be part of a craniofacial team to provide interdisciplinary care for patients. Distraction osteogenesis is a useful technique in the management of severe craniofacial deformities but does not replace conventional orthognathic surgery, which is safe and predictable. Recent advances in three-dimensional imaging and planning tools have made it possible to plan surgery more accurately and predictably.

Fixation of mandibular fractures: a tincture of science.

AIM: To critically review the literature regarding the fixation of mandibular fractures to gain direction on which type of fixation is indicated in which clinical setting. METHODS: A critical review of the literature based on computer searches using the Medline and Cochrane databases. The years searched were 1987 to 2002. Keywords used were: mandibular, fracture, fixation and osteosynthesis. RESULTS: Eight hundred and thirty-four citations were obtained of which 127 were for case reports, orthognathic surgery or veterinary science. Thirty-nine citations dealt with non-clinical testing and four examined cost related to different treatment modalities. Six hundred and sixty-four citations were for articles reporting clinical experience, technical variations, comparative series, or proposed treatment protocols. Only a handful of papers reported studies sufficiently well designed to permit conclusions to be drawn on the relative success of various treatment approaches. CONCLUSION: The published literature on the fixation of mandibular fractures falls well short of that required for evidence based surgery.
