OBJECTIVE: To evaluate epidemiological aspects of maxillofacial injuries in hospitalized patients. METHODS: The sample was composed of 405 patients treated at the Department of Oral and Maxillofacial Surgery of the Emergency Hospital of Aparecida de Goiânia, Brazil, between 2011 and 2013. The following informations were collected from the patients' medical records: gender, age, cause of injury, seasonal distribution and type of injury. The statistical treatment analyzed data from frequency distribution and chi-squared test. The level of significance was set at 5% for all analyses. RESULTS: A higher occurrence of maxillofacial injuries was observed in males (72.59%) and with 21-30 years old (26.17%). The main etiologic factors involved were vehicle traffic accidents (30.62%), falls (22.72%) and violence (21.48%). The seasonal distribution showed that most cases occurred in autumn (38.02%), followed by summer (34.07%). The most common injuries were facial fractures (80%), with the nasal bones being the most affected anatomical region (39.75%). Statistically significant associations between etiological factor, gender and age (p<0.005) were observed. CONCLUSION: There was a high number of maxillofacial injuries in males aged less than 30 years old due to vehicle traffic accidents.

The median palatine cyst is a rare benign nonodontogenic lesion that attacks the median palatine suture. There is controversy about its pathogenesis; however, its origin is generally attributed to the enclavement of epithelial remnants within the palatine suture between the 2 lateral maxillary processes during their fusion in the origin of the hard palate. The purpose of this report was to relate a case of a median palatine cyst, discussing the rarity of the lesion, its pathogenesis, and the different modalities that could be used for the correct treatment of this pathologic entity.

Dental implant surgery is a common procedure in oral and maxillofacial surgery practices. Extensive training, skill, and experience allow this procedure to be performed with an atraumatic approach, but like any surgical technique, it is subject to accidents and complications. This is an unusual clinical case of an accidental displacement of an implant into the submandibular space that progressed to Ludwig's angina, and it has not yet been described in the literature. This case report describes a clinical case of dental implant displaced into the submandibular space after healing cap removal. After seven days, it progressed to Ludwig's angina. The removal was performed through extraoral access in the submandibular area by using hemostatic forceps and radioscopic technique. After implant removal, the clinical case showed a satisfactory repair emphasizing the importance of a meticulous clinical planning to achieve an appropriate treatment plan, which is essential for a favorable prognosis. Therefore, prevention and management of displaced objects requires proper planning and surgical technique.
