The fundamental principles and the role of surgeons and orthodontists to produce successful results in orthodontic treatment combined with orthognathic surgery is not different from those of conventional procedures and FOS: surgery-first-orthodontic-treatment-later approach. The communication and cooperation between surgeon and orthodontist is of crucial importance. In FOS, the pre-surgical orthodontic preparation is not carried out in the patient's mouth, but in the mounted stone model and in addition to the simulation of tooth movement, to get a precise surgical occlusion, the entire steps of treatment should be simulated on the articulator as well. Right after the surgery, due to the instability of the occlusion, appropriate post operational care should be given according to the surgical technique applied to the mandible by use of final surgical wafer about 8 weeks.

Orthognathic surgery(2-jaw or 1-jaw surgery) is very famous one of cosmetic techniques. However, primary purpose of orthognathic surgery is to improve the occlusion of jaw and secondary purpose is to improve the esthetic result. Unfortunately, many patients don't only confuse often primary and secondary purpose of orthognathic surgery but they think the esthetic result is more important than the occlusion. Therefore, oral and maxillofacial surgeon has to fully understand cosmetic needs of patient and reflect that in the treatment plan. Patients with prominent mandibular angle want to have the narrower face of so called 'V-line' shape. Various techniques like the angle shaving, ostectomy of the lateral cortex around the mandibular angle and masseter musclectomy can be used for improving the mandibular angle hypertrophy. These techniques also can be applied in orthognathic surgery at the same time. We operated patients of orthognathic surgery, especially, with wide lower face and post-operative results were satisfactory in all cases. So, we propose mandibular angle management for improving the esthetic result of orthognathic surgery.

While oral and maxillofacial surgery such as orthognathic surgery, TMJ surgery is in progress, there always exists a risk of bleeding from maxillary artery, and this perplexes the surgeon in operation. In case of massive bleeding, it is mostly very difficult or even impossible to take an immediate action in order to stop bleeding. Even when hemostasis is possible by applying such methods as the use of local hemostatics, pressing, electrocoagulation or direct ligation, there is a high risk of secondary bleeding. Therefore, in case there is bleeding from maxillary artery, it is the best to restrain bleeding completely either by the ligation of the artery in bleeding in operation fields or by the ligation of the external carotid artery.

The management of malignant tumors of the oral cavity requires that the resection should be performed with adequate negative margins. To this end, the surgeon is sometimes required to increase the access to the oral cavity to resect with clear margins although most of our resections can be carried via the transoral route. This article highlights some of the most common surgical accesses to the oral cavity: Peroral approach, mandibulotomy and mandibular swing approach, visor flap approach, upper & lower cheek flap approach, pull-through technique. Also, various modes of management are grossly described according to primary site, size, and stage of the tumors.

Osteonecrosis of the jaw (ONJ) is a well-known pathological condition in oncology derived from the use of bisphosphonates (BPs) and denosumab. Many molecular and immunological targets have been introduced for daily use in cancer treatment in recent years; consequently, new cases of ONJ have been reported in association with these drugs, especially if administered with BPs and denosumab. When the drugs are administered alone, ONJ is rarely seen. The objective of our study was to analyze the recent literature relative to the association of ONJ with these new drugs highlighting the pathogenic, clinical and therapeutic aspects. The close collaboration between maxillofacial surgeon, oncologist, dentist, and dental hygienist remains the most important aspect for the prevention, prompt recognition, and treatment of this pathology.

Introduction: Surgical extraction of third molar is one of the most frequently performed procedures in oral and maxillofacial surgery unit as the impacted wisdom teeth could cause various complications. Even though, however, extraction of the impacted wisdom teeth is an obligation for the reason of possible complication even for general practitioners, it has been avoided. Various factors concerning surgical extraction of impacted third molar are considered: general condition of patients, relationship with relative anatomies, aspects of impaction, surgeon's skill. Materials and Methods: The consideration and crossing analysis of these factors with 2,463 patients who visit Dankook University dental hospital to extract those impacted third molar. Results: 1. Gender doesn't affect. 2. Medical problems have more complications. 3. There are more complications in high difficulty index (DI) impacted teeth. 4. When inferior alveolar canal overlap mandibular third molar, complication rate is 26.92%. 5. The most common complication was swelling and pain. 6. There is no statistical difference between the incidence of complication and surgeon's experience. Conclusion: In regard to these results, it seems that clinical or radiological examination can predict potential complications of wisdom teeth, and it is helpful to bear in mind the fact.

Objectives: Appropriate and accurate local anesthetic (LA) techniques are indispensable in the field of oral and maxillofacial surgery to obtain a satisfactory outcome for both the operating surgeon and the patient. When used alone, the inferior alveolar nerve block (IANB) technique requires supplemental injections like long buccal nerve block for extraction of mandibular molars leading to multiple traumatic experiences for the patient. The aim of this study was to anesthetize the inferior alveolar, lingual, and long buccal nerves with single-needle penetration requiring a minimal skillset such as administering a conventional IANB through introduction of the Benny Joseph technique for extraction of mandibular molars. Materials and Methods: This was a prospective study conducted in the Department of Oral and Maxillofacial Surgery, Kunhitharuvai Memorial Charitable Trust (KMCT) Dental College, Calicut, India. The duration of the study was 6 months, from June to November 2017, with a maximum sample size of 616 cases. The LA solution was 2% lignocaine with 1:100,000 adrenaline. The patients were selected from a population in the range of 20 to 40 years of age who reported to the outpatient department for routine dental extraction of normally positioned mandibular right or left first or second molars. Results: Of the 616 patients, 42 patients (6.8%) required re-anesthetization, a success rate of 93.2%. There were no complications such as hematoma formation, trismus, positive aspiration, and nerve injuries. None of the cases required re-anesthetization in the perioperative period. Conclusion: The Benny Joseph technique can be employed and is effective compared with conventional IANB techniques by reducing trauma to the patient and also requires less technique sensitivity.

Cutaneous lymphoid hyperplasia (CLH) is a cutaneous pseudolymphoma with a worldwide distribution, equally affecting all races and ethnic groups. Due to its vast array of characteristics, it is most often missed in the differential diagnosis of firm to soft lumps on the head and neck. A systematic approach to the workup and diagnosis along with treatment of such lesions is discussed in this article. A 20-year-old Asian Indian female presented to our Oral and Maxillofacial unit with a lump on the left side of her forehead for 1 month. Local examination revealed a $2.5{\times}3.0cm^2$, well circumscribed swelling over the left para median region that was firm to doughy and non-tender. There was no other significant finding on general examination. Excisional biopsy of the lesion was performed, followed by histopathologic processing. The general etiology, pathogenesis, clinical presentation, differential diagnosis, clinical course, prognosis, treatment, and prevention have been discussed in line with the recent modalities of diagnosis and treatment of CLH. Due to the overlapping clinical and histological characteristics of CLH with many other lesions, it is important to consider this lesion in the differential diagnosis of cutaneous lesions.
