Coronavirus disease 19 (COVID-19) is associated with respiratory complications but also with alterations on bone metabolism. Coronavirus disease 19, therefore, might be a risk factor for osseointegration. Recent studies suggest that severe acute respiratory syndrome coronavirus 2 is related with bone abnormalities mainly for act via renin-angiotensin system. This report aims to list the bone alterations caused by coronavirus disease 19 and the possible consequences on the peri-implant bone healing. The current data add to the accumulating knowledge that coronavirus disease 19 may negatively impact the osseointegration and it requires further research.
As lesões faciais causadas por arma de fogo ainda são motivo de muita preocupação no âmbito da saúde pública e podem causar grandes prejuízos estéticos e funcionais para o paciente, além de perda de qualidade de vida. Sendo assim, o objetivo deste estudo é relatar um caso clínico de paciente do sexo masculino, 39 anos, encaminhado por policiais militares à equipe de cirurgia e traumatologia bucomaxilofacial para avaliação de lesão facial apresentando trauma em face decorrente de projétil de arma de fogo, foi submetido à cirurgia para a remoção do projétil e reconstrução maxilofacial em ambiente hospitalar, sob anestesia geral, devido às condições sistêmicas do paciente. Foi removida a jaqueta do projétil alojada em mucosa jugal direita e fragmentos dentários que se encontravam na linha de trajeto do projétil. Notou-se mobilidade do segmento anterior da mandíbula e lacerações em mucosa oral interna. No quarto dia foi realizada glossectomia parcial, em região de terços anterior e médio e fixação de fratura. Optou-se pelo acesso extraoral, realizou-se remoção de fragmentos ósseos, redução da fratura em sínfise, instalação de placa de reconstrução do lado esquerdo e placa e parafusos de 2,0 mm em sínfise, sendo os parafusos bicorticais em zona compressiva e monocorticais em zona de tração. Foi possível concluir que a redução aberta com fixação com placas e parafusos é uma boa opção de tratamento para fraturas cominutivas causadas por projéteis de arma de fogo, devolvendo ao paciente aspectos estéticos, funcionais e psicológicos.Descritores: Ferimentos por Arma de Fogo; Fraturas Mandibulares; Glossectomia.
Inappropriate treatments of frontal sinus fractures may lead to serious complications, such as mucopyocele, meningitis, and brain abscess. Assessment of nasofrontal duct injury is crucial, and nasofrontal duct injury requires sinus obliteration, which is often accomplished by autogenous grafts such as fat, muscle, or bone. These avascular grafts have an increased risk of resorption and infection and donor site morbidity. For these reasons, pericranial flap, which is vascular, should be used for frontal sinus obliteration. The pericranial flap presented with less morbidity procedure and has decreased infection rates, which justifies its use in frontal sinus obliteration. This study aimed to report a case of a comminuted frontal sinus fracture with a brief literature review, regarding the use of pericranial flap. The authors report a case of a 23-year-old male subject with a severely comminuted fracture of the anterior and posterior walls of the frontal sinus. The patient was successfully treated by cranialization with frontal sinus duct obliteration, using anterior pericranial flap. The patient was followed up for 16 months with no postoperative complication, such as infection. Pericranial flap is a good resource for frontal sinus duct obliteration because it is a durable and well-vascularized flap, which determines low rates of postoperative complications.
Foreign bodies can be found in the soft tissues of the face and in the maxillary bones in routine radiographic examinations. In the majority they do not present symptomatology. The removal of foreign bodies without the accurate location can cause severe complications. We present a case of 44-year-old male complaining an unusual foreign body in the lower lip region. Radiography did not reveal the exact location, and did not let a resolution at first time. Subsequently, the surgical treatment was effective with the aid of navigation-assisted fluoroscopy that showed the precise location of the foreign body for removal and avoided more discomfort to the patient.Descriptors: Foreign Bodies; Fluoroscopy; Traumatology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
