The aim of this study is to evaluate the incidence of ophthalmic complications following midfacial fractures and investigate its relation to surgical or nonsurgical treatment. This article is a retrospective study, describing the spectrum and incidence of ophthalmic injury in 106 patients presenting with midfacial fractures at the Department of Oral and Maxillofacial Surgery of the University Hospitals Leuven over a period of 16 months (January 2013 to April 2014). The mean age of the patients was 45.6 years with a gender distribution of 68 men and 38 women. The main cause of trauma was road traffic accidents. Forty-one patients suffered an ophthalmic injury following the fracture. Twelve of them had a persistent ophthalmic problem. Ophthalmic examination is necessary during the initial management. The time window for preservation of sight is small and treatment should be started immediately. Development of an emergency trauma scale that includes fractures, symptoms of visual impairment, and patient history is recommended and should stimulate a multidisciplinary approach of complex cases.

Medication-induced jaw osteonecrosis (MRONJ) is a rare and serious disease with a negative impact on patients’ quality of life, whose exact cause remains unclear and which may have a multifactorial origin. Although there are different therapeutic protocols, there is still no consensus. This case series evaluated three patients diagnosed with staged 2 MRONJ treated at the University of Murcia dental clinic according to the protocols described by the Spanish Society of Oral and Maxillofacial Surgery and the American Association of Oral and Maxillofacial Surgeons. Within 12 months of the application of therapeutic protocols, the lesions were completely healed in all cases. Radiography showed slow but progressive healing with normal bone structure. Conservative treatment with antibiotics, chlorhexidine rinses and minimally invasive surgical intervention with necrotic bone resection is effective in treating stage 2 of MRONJ. In cases of refractory osteonecrosis, the application of platelet and leukocyte-rich fibrin (PRF-L) in the surgical approach improves the outcome in soft tissue healing and bone regeneration but further research is needed to confirm its effectiveness.

Risky driving behavior is a major cause of traffic conflicts, which can develop into road traffic accidents, making the timely and accurate identification of such behavior essential to road safety. A platform was therefore established for analyzing the driving behavior of 20 professional drivers in field tests, in which overclose car following and lane departure were used as typical risky driving behaviors. Characterization parameters for identification were screened and used to determine threshold values and an appropriate time window for identification. A neural network-Bayesian filter identification model was established and data samples were selected to identify risky driving behavior and evaluate the identification efficiency of the model. The results obtained indicated a successful identification rate of 83.6% when the neural network model was solely used to identify risky driving behavior, but this could be increased to 92.46% once corrected by the Bayesian filter. This has important theoretical and practical significance in relation to evaluating the efficiency of existing driver assist systems, as well as the development of future intelligent driving systems.

OBJECTIVETraumatic brain injury due to road traffic accidents occurs mainly in the younger age group in which injury-related disability leads to long-term impact on employment and economic and social consequences across the lifespan. This study was designed to assign a monetary cost (in Malaysian ringgits [RM]) to the treatment of patients with surgically treated isolated traumatic head injury as determined up to 1 year after injury.METHODSRelevant resource items used were identified and valued using the direct measurement of costs method, cost accounting methods, standard unit costs method, fees, charges and/or market prices method. These values were then tabulated to generate the total costs for each patient, via a combination of macro-costing and micro-costing methods. Malaysian currency values were converted to US dollars according to the average conversion rate for the period from January to May 2016: RM1 = US$0.2452.RESULTSThis costing study analyzed data from 49 patients. The estimated cost for the 1st year of care for all patients was RM1,471,919.80 (US$360,914.735), with a mean (± SD) cost per case of RM30,039.18 ± 22,986.25 or $7365.61 ± $5636.23. The mean cost of care per case was RM11,041.35 ± 10,936.88 or $2707.34 ± $2681.72 for mild head injury, RM32,550.00 ± 20,998.76 or $7981.26 ± $5148.90 for moderate head injury, and RM36,917.86 ± 23,697.34 or $9052.26 ± $5810.59 for severe head injury. Severe head injury (p = 0.001), sustaining 2 or more intracranial pathologies (p = 0.01), having a poor Glasgow Outcome Scale (GOS) score (GOS score 1–3) (p = 0.02), requiring a tracheostomy (p < 0.001), and contracting pneumonia (p < 0.001) were significantly associated with higher cost. Logistic regression analysis revealed that cost of care increased by RM591.60 or $145.06 per year increment of age (β = RM591.60, p = 0.05).CONCLUSIONSThe mean cost of treatment for traumatic head injury is high compared to the per capita income of RM37,900 in 2016. The cost values generated in this study provide baseline cost estimates that the authors hope will be used as a guide to determine where adequate funding should be allocated to provide timely and appropriate delivery of care.

Background/Aim. Epidemiology of maxillofacial fractures (MFF) varies between populations. This study investigated the epidemiology of MFF treated at the Oral and Maxillofacial Surgery (OMFS) Unit, Hospital Universiti Sains Malaysia (USM).Methods. A retrospective review of 473 medical records of patients with MFF treated from June 2013 to December 2015 was conducted. Information on demographic characteristics of patients, aetiology of injury, types of MFF, and treatment was obtained. Descriptive analysis, Pearson's chi-squared test, and multiple logistic regression analysis were conducted. The level of significance was set at 0.05.Results. Most patients treated for MFF were males (82.2%), aged 30 and below (63.1%), and from Malay ethnic (97.4%). Road traffic accident was the most common cause of MFF (83.1%), with motorcycle accident accounting for most injuries (73.6%). Orbital wall fracture was the most frequent MFF type (51.2%). About half of MFF patients (51.4%) were treated conservatively. Patients aged more than 20 years old were at higher odds of sustaining orbital wall fracture (AOR= 1.76; 95% CI: 1.214-2.558;P= 0.003) but were at lower odds of sustaining mandibular fracture (AOR= 0.47; 95% CI: 0.315-0.695;P= 0.001) than patients who are 20 years old and younger. Helmet use among motorcyclists was significantly associated with the nasal, orbital wall, and maxillary sinus wall fractures (P=0.006, 0.010, and 0.004, respectively).Conclusion. Motorcycle accident was the most common cause of MFF in Kelantan, Malaysia. Ages of patient and helmet use were associated with the type of MFF sustained. This study provides important information to facilitate the planning of MFF prevention strategies among motorcyclists and emphasizes the importance of using a helmet when riding a motorcycle.

Background and Objectives: Large radicular cysts of the maxilla present a clinical challenge, as they may cause recurrent infection, severe alveolar bone loss and disruption of the nasal and maxillary sinus floors. The aim of this study was to evaluate the effect of previous root canal treatment on the clinical presentation of large maxillary radicular cysts. Materials and Methods: All cases of radicular cysts treated at the Oral and Maxillofacial Surgery Department of a tertiary public hospital over a period of six years (2012–2018) were evaluated. Histologically confirmed radicular cysts of the maxilla with a maximal dimension of over 15 mm were included. Demographic data of the patients, clinical presentation and radiographic features of the lesions were analyzed. Results: A total of 211 inflammatory cysts were treated in the study period, of these 54 histologically diagnosed radicular cysts in the maxilla were found to have a maximal dimension of over 15 mm. The mean age of patients with large maxillary radicular cysts was 43.3 years, 57.6% of which were male and 42.4% female. The lateral incisor was the most common tooth affected (46.3%). The mean size of the large radicular cysts was 25 mm. Then, 83.8% of the cysts were observed in teeth with previous endodontic treatment. Teeth without endodontic treatment presented clinically with significantly fewer acute symptoms in comparison to teeth with previous endodontic treatment. Conclusions: the vast majority (83.8%) of large maxillary radicular cysts were associated with endodontically treated teeth. Previous endodontic treatment was correlated to increased frequency of clinical symptoms.
