Abstract
Cancer is considered as one of human's complications, particularly in oral and maxillofacial region which leads to undesirable effects and sometimes endangers individual's life. The aim of this study was to investigate the frequency of maxillofacial malignant tumors, during 13 years, (1985- 1998),in Hamedan. Three hundred and eighty - six records of biopsies were selected from the private files of physicians, 7 private and governmental pathological centers and other educational and research organizations in Hamedan. After observing the samples by oral pathologist, they were presented as the statistical population for this retrospective study. The highest rate of biopsies was observed in the sixth (42.7%), seventh (39.6%) and third (10.6%) decades. The average age was 43.5 years, for women and 1.52 45.5 for men. The ratio of men to women was . The oldest patient was a 91- year - old man with malignant melanoma, while the youngest was a 3-year-old girl with Burkit lymphoma. The commonest site of involvement was nasal region (17.3%) and the anterior neck triangle showed the least common tumoral site (2.3%). The commonest tumor, observed in this study, was BBC (41.4%) and the least common was malignant fibrous histocytoma (0.2%). Baso cellular and epidermoid carcinomas have been the commonest cancers in this investigation, while lymphoma and salivary galnd cancers have been placed as the second ones. The results of this study showed that the lower lip and tongue are considered as the commonest sites for cancer.

Abstract
Nowadays, sport injuries constitute a major part of social accidents. The aim of the present study, was to investigate the frequency of maxillofacial injuries among athletes-members of different sports federations in Iran from 1998-2001. For this reason files which was related to sport injuries of men and women athletes-members of sports federations were studied in Medical Federation of the Islamic Republic of Iran Sports Organization. The information were received through 26 medical organizations,located in different states of the country. The results showed that maxillofacial injuries constitute the major part of the sports injuries. In male athletes, football was the most important cause for maxillofacial injuries. However, mountain climbing and skiing play the least role in this field. Among female athletes,karate was the cause of the highest rate of maxillofacial sport injuries. Diving, mountain climbing and skiing cause the least number of maxillofacial accidents. Nasal fracture was the most common sport injury among Iraninan male and female athletes.

Abstract
Distraction osteogenesis (DO), firstly introduced to the medical world by Russian scientist Ilizarov for long bone lenghtening in orthopedics can be considered as an appropriate substitute in the treatment of maxillofacial deformities. Natural events occuring during the repair of a fractured bone segment not only lead to the desired bone length but also prevent from the undesired disadvantages of osteotomies and bone grafting. Recently a lot of investigations have been conducted to evaluate the efficacy of DO in the treatment of maxillofacial deformities, which in some cases have lead to successful results. In the present article a lot of issues in maxillofacial surgery and different treatment goals associated with DO are discussed.

Abstract
A procedure was explained to fabricate a surgical stent to aid the placement of maxillofacial implants for prosthetic auricular rehabilitation. An impression of the defect was made, and a wax pattern of the missing ear completed and evaluated on the patient. The definitive wax prosthesis was processed in clear acrylic resin. Also an occlusal maxillary splint was fabricated and joined to the acrylic resin ear by using an extraoral acrylic resin bar. Surgical stent provides proper orientation of the acrylic resin ear while remaining attached to the maxillary arch. This surgical stent can also be used for radiographic examination.

Abstract
Background and Aims: Despite advances in trauma management, treatment of the consequent infections has remained a major challenge. Antibiotic prophylaxis has been widely applied to reduce such infections. Although bacteria are present in most body parts, severe infections after treatment are less frequent in the head and neck of healthy individuals. The aim of the present study was to review the reasonable application of antibiotic prophylaxis in maxillofacial trauma.
Materials and Methods: In this review article, PubMed and Google Scholar databases were searched for studies on antibiotic prophylaxis in maxillofacial trauma published during 2000-2014.
Conclusion: Antibiotics were not prescribed for tears and small clean wounds in the face and mouth. However, prophylaxis was applied for extensive mouth injuries which involved the facial skin. In case of maxillofacial fractures, 24-hour administration of antibiotics sufficed for compound fractures of the mandible and other parts of the face. Antibiotics were not required in other types of fractures. Prophylaxis should be applied over short pre- or post-operative periods based on the severity and complexity of maxillofacial fractures and their relations with intra- and extraoral environments. Apparently, more detailed studies are warranted to further clarify the subject.

Abstract
Background and Aims: Fractures of the facial bones and jawbones could cause functional problems along with social and cosmetic problems. Various factors (including road accidents, assault, falling from height, sport injuries, and getting hit by a hard object) could cause these fractures. Collecting and reporting accurate epidemiologic data regarding the facial fractures are major steps toward planning preventive measures. The aim of this study was to collect the epidemiologic data regarding maxillofacial fractures in two referral centers (Shariati and Sina hospitals) in the city of Tehran.
Materials and Methods: The study was a cross-sectional retrospective investigation. All the necessary data were collected from the patients’ files and analyzed using SPSS 25.
Results: The present study pursued data of 454 trauma admitted patients in oral and maxillofacial surgery wards of Shariati and Sina hospitals in 1397 and 1398. These data showed that a number of 374 patients of all patients were men and the other 80 were women. The ratio of male patients to female patients was 4.5:1. In 290 of cases (64%), the fractures occurred as combined fractures and in 164 cases (36%), the fractures occurred as single fracture. These fractures happened mostly in the mandibular bone and in mandibular body, and the least of these fractures happened in Orbit. This study showed that there was a significant relation (with 95% confidence level) between the mandibular body fractures and mandibular angle fractures. This study also showed that there was another significant relation (with 95% confidence level) between the mandibular angle fractures and LeFort 2 fractures. In addition, this study also showed (by using k2 exam) a relation between the etiology of trauma and the number of fractures.
Conclusion: This present study showed that the maxillofacial fractures happened mostly in men much more than women. If we put motorcycle accidents and car accidents in a group together called road accidents, the most common etiology of maxillofacial fractures is road accidents. The results showed that the most fractures happened in the age range of 15-25 year old.
