Individuals in the most productive age group are most affected, which causes a great loss to financial and labor systems. It is important to take measures to alert the public regarding the severity of injuries likely to occur in motorcycle-related accidents and ways to prevent them.

Epithelial-myoepithelial carcinoma was first described by Danath et al. in 1972 and is classified as a rare low-grade biphasic neoplasm of the salivary glands. This case report presents a male patient who had a lesion in the oral mucosa with a history of recurrence of the tumor. The outcome resulted in a profile consistent with an epithelial-myoepithelial carcinoma with a high degree of transformation. The case highlights the importance of histopathological evaluation of oral lesions, which occasionally may not present typical clinical aspects of malignant lesion.

Adult females were affected by facial trauma more than the other age groups studied, with a predominance of soft tissue injuries and injuries to the mandible, maxilla, zygomatic arch and nasal bones. Falls were the most prevalent cause of facial trauma and significantly associated with the youngest (children/adolescents) and oldest (elderly individuals) age groups.

Periosteal osteoma is a rare benign pathologic lesion in the jaws and the mandible is the anatomic region most frequently involved. Elective treatment consists of surgical excision. The aim of this report was to report a rare case of bilateral periosteal osteoma involving the mandible--a painless, firm, and well-circumscribed lesion, with more bony prominence on the left than on the right side. The patient had no history of facial trauma or systemic changes that could intervene with the progression of the lesion. It was diagnosed as a periosteal osteoma, and surgical excision was performed. No recurrence after 4 years of follow-up was demonstrated. Surgical excision of the periosteal osteoma was demonstrated to be a useful technical strategy that simplifies and accelerates the surgical procedures and probably contributes to establish harmony of the jaws. Periodical clinical and radiographic follow-ups after surgery are advised.

Currently, imaging techniques such as Computed Tomography with three-dimensional reconstruction (3D) and Magnetic Resonances are being routinely used in pre-surgical planning in all fields of medicine. Nowadays, virtual three-dimensional images, commonly displayed on two-dimensional surfaces, such as the computer screen, can be used to produce rapidly prototyped models, with excellent dimensional accuracy and fine reproduction of anatomical structures, providing professionals with the ability to use the biomodel in planning and simulating medical and dental procedures (oral and maxillofacial surgery, making individualized facial implants and prostheses, measurements and previous adaptations of prefabricated fixation plates), thus contributing to considerable reductions in surgical time and consequently the duration of anesthesia, minimizing infection risks and reducing hospital costs. In this report, we describe a case of surgical planning and treatment of bilateral atrophic mandibular fracture, in which, for surgical planning, authors used Rapid Prototyping as an adjunct tool, considering the advantages already outlined.

Inf ormation contained in the present study can better explain the type of care performed in this service, which is paramount in order to plan, organize and improve medical care here. Aim: the goal of the present study was to carry out a retrospective epidemiological study concerning facial trauma from August 2006 to August 2007. Materials and Methods: 211 charts were studied in order to collect patient data regarding the number of patients seen, gender, age, year and their origin, surgical approaches and cases. Results: Among the surgical cases, facial fractures were the most prevalent (73.9%). Male patients prevailed (81.5%), in the ages between 11 and 40 years from the arid Paraíba mesoregion. The most frequent causes we motorcycle accidents, making up 64.5% of the sample, and the zygomatic-orbital complex was the most affected site. Conclusion: The most affected patients were males, and those from the Paraíba arid mesoregion were the ones who benefited the most from the service. Among the most frequent etiological factors we list: motorcycle accidents, physical fights and falls from one's own height.

the measurements demonstrated strong agreement between examiners and significant reliability and reproducibility. Therefore, this methodology can serve as a standard for linear measurement analysis of the topography of mandibular canal and osseous adjacent structures.
