ABSTRACT

PURPOSE: This article consists of a systematic review of the literature, which verified whether the use and types of helmets reduce the occurrence and severity of facial fractures in hospitalized motorcyclists after traffic accidents. MATERIALS AND METHODS: Prevalence studies and cohort studies, published in Latin American languages with no restrictions on publication dates, were considered. Two authors independently screened reference lists for eligible articles, assessed them for inclusion criteria, and extracted the data using a specific form. Twenty-six articles were selected, all prevalence studies. RESULTS: The patients who used a helmet had a lower prevalence and severity of facial fractures, compared to patients who did not wear a helmet. There were no differences in the occurrence of lower third fractures between patients who used or did not wear a helmet at the time of the trauma; as well as in meta-analysis of occurrence and severity of facial trauma between helmet types (open or closed). CONCLUSIONS: It can be concluded that the use of helmet leads to a lower number of fractures and severity of trauma when compared to nonuse. Regarding the type of helmet, there was no difference in the occurrence and severity of facial fracture in individuals who used closed or opened helmets.

ABSTRACT

Ameloblastomas são tumores dos maxilareslocalmente agressivos com uma alta propensão pararecorrência e acredita-se que surgem a partir de restos dalâmina dental ou epitélio odontogênico. A cirurgia radicalcontinua a ser a terapia de escolha. Relato do caso:Apresentamos um caso onde uma paciente de 69 anos deidade, aproximadamente oito anos após hemi-mandibulectomiapara tratamento de ameloblastoma multicístico, procurou oserviço de cirurgia buco-maxilo-facial do Hospital UniversitárioOswaldo Cruz, em Pernambuco, Brasil, apresentandoaumento de volume intrabucal doloroso, bem delimitado, emedindo cerca de 4 cm na submucosa adjacente à placa detitânio que foi usada para a reconstrução. Uma tomografiacomputadorizada e uma biópsia incisional foram realizadas.A lesão foi diagnosticada como ameloblastoma. Os tumoresforam ressecados e análise anatomopatológica revelou umameloblastoma predominantemente folicular e acantomatosodentro de intensa fibrose, configurando uma recorrência emtecidos moles. Comentários: Este relato mostra anecessidade de monitoramento de ameloblastomas, por umperíodo de longo prazo mesmo após o tratamento radical...


Ameloblastomas are locally aggressive jawtumors with a high propensity for recurrence and believed tooriginate from remnants of dental lamina or odontogenicepithelium. Radical surgery still remains the first-choicetherapy. Case Report: Herein we report the case of a 69-year-old patient admitted to the University Hospital OswaldoCruz in Pernambuco, Brazil, exactly eight years afterundergoing hemi-mandibulectomy for treatment of a multicysticameloblastoma. The patient complained of painful, welldelimitedswelling measuring about 4 cm in submucosa nextto a titanium bone plate that was used for reconstruction.Computed tomographic imaging and incisional biopsy wereperformed. The lesion was diagnosed as a ameloblastoma.The tumor was resected and histopathological analysesshowed predominance of follicular and acanthomatousameloblastoma within a highly fibrotic area, thus completingthe diagnosis of soft-tissue recurrence. Considerations: Thisreport shows the need of monitoring ameloblastomas for along-term period even after radical treatment...
