Conventional methods for diagnosis and operation planning based on 2D image are still widely used in oral and maxillofacial prostheses surgery, and the accuracy and efficiency are needed to improve eagerly. Aiming at this problem, rapid prototyping (RP), a technique of advanced manufacturing, is applied to fabricate the physical model of bone, and which is used to simulate the operation further. The procedure of RP based precise surgery is presented, and some key techniques including CT image processing, 3D bone model reconstruction, repairing model design, physical model fabrication, pre-operation simulation are discussed in detail. Total 25 successful clinical applications illustrate that, with RP based precise surgery methodology, the efficiency and quality of oral and maxillofacial prostheses can be improved effectively.

Mandibular Third Molar

Third molar extraction is one of the most commonly performed minor surgical procedure in any dental practice worldwide, often accompanied by various postoperative sequelae such as swelling pain and trismus which intern affects the quality of life of a patient. Over the past few decades, different methods have been proposed in the literature and were clinically evaluated to reduce the postoperative discomfort after mandibular third molar impaction and out of which corticosteroids, have shown promising results. Dexamethasone (administered either orally, submucosally, IV or IM), methylprednisolone acetate and methylprednisolone sodium succinate (IV or IM or submucosal) are most commonly preferred corticosteroids in oral and maxillofacial surgery. The main objective is to systematically review the comparison of the effectiveness of submucosal administration of dexamethasone with methylprednisolone following mandibular third molar impaction in reducing the postoperative sequelae, and its discomfort and searches were performed in the PubMed, Medline, Scopus, and Cochrane Library databases. Two articles were most relevant, and the results of the comparison of the selected articles were analysed. From this deliberate audit, it is very well may be inferred that submucosal injection of dexamethasone plays a promising role in reducing the postoperative sequelae which includes swelling, pain and trismus and its discomfort following mandibular third molar impaction when compared with that of methylprednisolone.

Case Outcome

Abstract Aim Mortality and Morbidity (M&M) meetings form a critical part of clinical governance however they often suffer from hindsight bias and lack objectivity. To combat this, Kahoot surveys were disseminated to senior clinicians prior to M&M meetings. Each case to be discussed is presented as a survey item with the clinical and radiographic information that was available to the performing surgeon pre-operatively and participants are asked to detail their ideal treatment. The aims of this study were to determine if the introduction of Kahoot surveys prior to M&M meetings improves the objectivity of the discussions and reduces the effects of hindsight bias. Method A 12-item questionnaire relating to the introduction and utility of Kahoot surveys prior to M&M discussions was distributed to all registrars and consultants within our department. Result An 80% response rate was obtained (16/20 responses). Prior to the introduction of Kahoot surveys, 62.6% of surgeons felt case discussions were clouded by the benefit of hindsight. Comparatively, 68.8% indicated the use of pre-M&M surveys reduced the effects of hindsight bias. 56.3% of participants expressed the objectivity of case discussions improved and 50% felt the quality of feedback improved. Conclusions The use of Kahoot surveys prior to M&M meetings demonstrates that withholding the case outcome until each clinician has given their own opinion reduces the effect of hindsight bias. The surveys utilise the Bolam Test, thereby enabling us to determine the correct error classifications with greater objectivity. Furthermore, they facilitate a higher quality of discussion and feedback.

Objective: Evaluation of the quality of education and the relevant curriculum is one of the most important steps for optimizing the educational process. One of the ways to address the quality control is to continuously assess the postgraduate students’ opinions. This study aimed to evaluate satisfaction of senior postgraduate students of oral and maxillofacial surgery with the specialty curriculum. Materials and Methods: The target population in the present cross-sectional study consisted of all the senior postgraduate students in the field of oral and maxillofacial surgery all over Iran during the 2016−2017 educational year. The research questions consisted of 3 questions on demographic variables and 23 on educational variables, the characteristics of clinical education (including physical conditions and the number and varieties of the patients), the possibility of access to academic sources, the independent activity of post graduate students in taking history, the quality of educational activity of the professors, the quality of hospital wards and their interest in their field of study. Results: The mean age of the post graduate students was 32.4Å}3.8 and 93.5% % were male. Among the post graduate students, 58.1% were fully satisfied and 41.9% were moderately satisfied with the curriculum. A total of 64.5% of the post graduate students were fully satisfied with theoretical lessons, while 32.3% and 3.2% exhibiting moderate and low satisfaction rates, respectively. For practical training, 61.3% of the post graduate students were fully satisfied and 38.7% exhibited a moderate level of satisfaction. In clinical training, 7.38% of the post graduate students reported full satisfaction, while 58.1% and 3.2% reporting moderate and low rates of satisfaction, respectively. A total of 58.1% of the post graduate students were moderately satisfied with the facilities available and 41.9% reported a low satisfaction rate. Satisfaction was the same among females and males. Conclusion: Since the educational curricula and the educational facilities have been designed for high-quality education of the post graduate students, it is necessary to take the necessary steps to revise the curricula and improve the educational facilities.

Angle Fracture

Background: Mandibular fracture is the most common facial bone fracture. Fractures occurring at the Para symphysis region frequently results in mental nerve injury, due to which anaesthesia or paraesthesia of the skin and mucous membrane within the distribution of mental nerve may be observed and may cause reduced quality of life for patients. Aim of this study was to retrospectively analyse and evaluate the prevalence rate of mental nerve injury in patients that reported to the department of oral and maxillofacial surgery, managed conservatively or open reduction and internal fixation method during the last 3 yearsMethods: Patients with neurosensory deficit following para symphysis fracture were recorded, statistically analyzed and results and observation were prepared from it.Results: The patients with age group 21-30 diagnosed with para symphysis fracture constituted 25% of all operated case and were found to be more associated with midface and angle fracture. Etiology behind the trauma was mostly as a result of RTA. Neurosensory disturbances as a result of mental nerve injury were found to be associated in 20.89% case, out of which in most of the cases, it gradually recovered within a duration of 7-15 days.Conclusions: RTA’s have been a prime cause for para symphysis fracture, which may at times accompany neurosensory deficit following trauma or may occur post-surgery, has been found to cause troublesome sequelae and reduced quality of life. Moreover, further research study needs to be carried out over a larger time span having a larger group of patients.
