RESUMO

BACKGROUND/AIMS: Oral and maxillofacial trauma (OMFT) is a public health problem due to its high occurrence and demand for resources for its management and the financial and social impact of OMFT victims on the health system. The aim of this study was to conduct an 8-year prospective analysis of OMFT cases from an emergency service. MATERIALS AND METHODS: A hospital-based 8-year prospective study on OMFT and associated factors was performed on data from December 2011 to December 2019. Data regarding sociodemographic (gender, age, and skin color) and socio-economic profiles (educational level, family income, and occupation), OMFT profile (etiology, OMFT type, and treatment), associated factors [alcohol consumption and personal protective equipment (PPE) use], OMFT occurrence (injury day and hour), length of hospital stay, and cost were collected. Descriptive and inferential analyses of data were performed. RESULTS: Most OMFT cases involved men with low schooling and family income, resulting from traffic accidents. OMFT severity was associated with longer hospital stay, higher hospital costs and nonuse of PPE, midface fractures (mainly orbital-zygomatic fractures), closed reduction, and open reduction/internal fixation. Traffic accidents were the main cause of longer hospital stays for victims aged 41-60 years with better socio-economic status compared with cases that had higher hospital costs. In general, higher hospital costs were associated with victims of violence under 40 years of age, with low schooling and farmers. Alcohol consumption and non-use of PPE also contributed to increasing the length of hospital stay. CONCLUSION: Oral and maxillofacial trauma severity was associated with longer hospital stay and higher hospital costs. Associated factors such as alcohol consumption and non-use of PPE contributed to increase the length of hospital stay and OMFT severity.

RESUMO

Objetivos: Traçar o perfil epidemiológico dos pacientes com lesões buco-maxilo-faciais. Métodos: Estudo retrospectivo mediante análise de 344 fichas ambulatoriais ou prontuários médico-hospitalares. Resultados: O sexo masculino foi o mais prevalente, a faixa etária de 21 a 30 anos, a mais acometida (28,8%), com tendência altamente significante (p≤0,01). O acidente de moto foi o segundo principal agente etiológico (32,6%). Os traumatismos faciais foram mais prevalentes no domingo, no período da tarde (24,7%; p≤0,01). A maioria das vítimas de acidentes não fez uso de algum Equipamento de Proteção Individual e alegou ter consumido algum tipo de droga (22,7%). Conclusão: As lesões buco-maxilo-faciais é um tema amplo, que possui uma gama de etiologias distintas e envolve a interação de vários fatores. As injúrias provenientes dos acidentes motociclísticos contribuem para a morbimortalidade e para o aumento dos custos hospitalares... (AU)

Objectives: To outline the epidemiological profile of patients with buco-maxillofacial lesions. Methods: In this retrospective study, 344 outpatient records or medical records were analyzed. Results: The male gender was the most prevalent, the age group of 21 to 30 years was the most affected (28.8%), with a highly significant trend (p≤0.01). The motorcycle accident was the second major etiological agent (32.6%). Facial trauma was more prevalent on Sunday afternoon (24.7%, p≤0.01). Personal Protective Equipment was not used by most accident victims, who claimed to have used some type of drug (22.7%). Conclusion: Buco-maxillofacial lesions are a broad theme that has a range of distinct etiologies and involves the interaction of several factors. Injuries from motorcycle accidents contribute to morbidity and mortality and increase hospital costs... (AU)

RESUMO

O número de vítimas de traumatismo vem aumentando significativamente nos últimos anos, representando a terceira causa de morte no Brasil. O traumatismo facial, em especial as fraturas, determina graves consequências biopsicossociais em suas vítimas, podendo ocasionar desde a incapacidade temporária ou permanente até mesmo o óbito do paciente. O melhor entendimento sobre o tempo médio de internação hospitalar de vítimas de trauma de face é importante porque provê informações necessárias para o desenvolvimento de medidas para a redução deste tempo, dos fatores que o determinam e mais agilidade no tratamento para que o paciente retorne às suas atividades normais. Esta pesquisa se propôs a analisar o tempo médio de internação hospitalar de pacientes portadores de fraturas faciais submetidos a tratamento cirúrgico em dois hospitais de urgência e emergência da Paraíba, no período de janeiro de 2011 a dezembro de 2014. A pesquisa foi devidamente registrada no SISNEP (0119.0.133.000-11), sendo um estudo observacional, epidemiológico, utilizando procedimento estatístico descritivo e dados documentais secundários retrospectivos em que foram utilizados os prontuários dos pacientes com fraturas faciais atendidos pelo Serviço de Cirurgia e Traumatologia Buco - Maxilo- Faciais. De posse dos resultados, observou-se que o tempo médio de internação foi de 4,3 dias; os pacientes que foram vítimas de acidente motociclístico permanecem por até dois dias a mais internados que os traumatizados por outros agentes etiológicos; a região anatômica fraturada influenciou no tempo de internação, de forma que os pacientes que sofreram fraturas de Le Fort II, Le Fort III e fraturas múltiplas de face os que permaneceram em média por mais tempo internados...

Number of victims of trauma has been increasing significantly in the last years, representing the third highest cause of death in Brazil. Facial trauma, especially facial fractures, sets biopsychosocial severe effects for victim´s, may cause temporary or permanent incapacitation, even patient death. The better understanding about the mean time of hospitalization of victim's facial trauma is significant because supplies necessary information for development and assessment of measures for reducing this time, factors determine and more agility in treating to these patients return to normal activities. The aim of this research was to analyze the mean time of hospitalization in patients with facial fractures who underwent surgical treatment at two hospitals of emergency and trauma in Paraiba - Brazil from January 2012 to December 2014. The research was duly registered in SISNEP (0119.0.133.000- 11), being an observational and epidemiological study using descriptive statistical procedure and retrospective secondary data using medical records of patients diagnosed with facial fractures treated by Oral and Maxillofacial Service. With the results, it was observed that the mean length of hospitalization was 4.3 days; patients who were victims of motorcycle accidents remain for up to two more days interned traumatized by that other etiological agents; the anatomical area fractured influence in the time of hospitalization, such that patients that have suffered fractures, Le Fort II, Le Fort III and multiple fractures of the face that stayed around longer hospitalized...

RESUMO

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.
