Fraturas maxilomandibulares no hospital de ensino: perfil epidemiológico e percepção dos usuários / Maxillomandibular fractures teaching hospital: epidemiological profile and perception of users

Investigar o perfil epidemiológico dos pacientes com fraturas no complexo maxilomandibular e compreender a percepção desses usuários quanto ao evento trauma maxilomandibular. Método: Adotou-se o método misto, mediante uma abordagem quanti-qualitativa. A coleta de dados foi realizada nos meses de julho a novembro de 2014, nos retornos dos usuários juanto ao serviço odontológico. Utilizou-se uma entrevista semi-estruturada, com informações sociodemográficas dos usuários e três perguntas norteadoras. O referencial metodológico utilizado foi a análise de conteúdo de Bardin e a Teoria Geral da Enfermagem de Orem. Resultados: Predominaram indivíduos do sexo masculino, jovens, vítimas de acidentes com veículos mootorizados, com fraturas na mandíbula. Conclusões: Os resultados encontrados neste estudo permitem considerar que os indivíduos, vítimas de trauma de face e bloqueio intermaxilar, apresentam déficit no autocuidado, sobretudo nos aspectos da higienização bucal e alimentação, além de comunicação verbal prejudicada, que pode comprometer ainda mais suas necessidades...

Latero-terminal neurorrhaphy without removal of the epineural sheath: experimental study in rats

Termino-lateral neurorrhaphies have been used up to the beginning of this century. After this period, they have no longer been reported. We tested the efficacy of a new type of latero-terminal neurorrhaphy and evaluated the role of the epineural sheath. A group of 10 rats had the fibular nerve sectioned and the distal ending was sutured to the lateral face of the tibial nerve without removing the epineurium. All experiments were made on the right side, the left one remaining untouched in half of the animals of each group. The other half were denervated by sectioning and inverting the endings of the fibular nerves. In this way, tibial cranial muscles were either normal or denervated in the left side and reinnervated through latero-terminal neurorrhaphy in the right side. After 7.7 months, the animals were subjected to electrophysiological tests, sacrificed, and the nerves and muscles were taken for histological exams. A response of the tibial cranial muscle was obtained in 75% of the animals. The distal ending of the fibular nerve showed an average of 498 nerve fibers. The average areas of the reinnervated tibial cranial muscles were (mu 2):841.30 for M2n and 1798.33 for M2d. We concluded that the termino-lateral neurorrhaphy was functional, conducting electrical stimuli and allowing the passage of axons from the lateral surface of a healthy nerve, to reconstitute the distal segment of a sectioned nerve. The presence of the epineurium was no impediment to axonal regeneration or to the passage of electrical stimuli.(ABSTRACT TRUNCATED AT 250 WORDS)
