Objetivo: Relatar um caso clínico de fratura panfacial, ressaltando a complexidade deste tipo de trauma e a abordagem de tratamento cirúrgico escolhida. Discussão: Um paciente de gênero masculino, 25 anos, deu entrada no Hospital Universitário do Oeste do Paraná, vítima de acidente automobilístico com múltiplas fraturas na face e evisceração do olho esquerdo. Permaneceu internado na UTI por vinte dias e, após mel¬hora clínica, foi submetido à cirurgia para redução e fixação das fraturas faciais. Optou-se pela sequência de redução “de superior para inferior e de lateral para medial”. O paciente permaneceu com bloqueio inter¬maxilar por quinze dias, pois não se tratava de paciente colaborador. Evoluiu com mínimas sequelas esté¬ticas e com uma oclusão estável. Conclusão: As fraturas panfaciais traduzem-se pelo tipo mais complexo de trauma facial e exigem conhecimento apurado por parte do operador. Existem várias sequências propostas para a redução dessas fraturas e cabe ao cirurgião bucomaxilofacial o diagnóstico e a escolha do melhor tratamento para o paciente.
Osteoma is a benign osteogenic tumor, which is characterized the slow-growing proliferation of compact or cancellous bone. The etiology of the lesion is not well established. Among the hypotheses, the following are related: a traumatic factor, infectious processes, or true neoplasm due to the origin of cartilaginous cells. It can present at any age, usually in young adult individuals, with equal prevalence in both sexes. The clinical characteristics of the peripheral osteoma are represented by slow asymptomatic growth, which leads to swelling and, thus, facial asymmetry. When it is related to the mandibular condyle, this growth can cause functional impairment, such as malocclusion, temporomandibular joint dysfunction, and even limited mouth-opening owing to ankylosis.
A modified submandibular access is a safe and reproducible procedure providing excellent functional results. This procedure has been routinely performed in our department.
To assess the stability of mandible position after orthognathic surgery for correction of class III skeletal malocclusion. Twenty adult males, aged 18 to 40 years, with Angle class III skeletal malocclusion underwent preoperative orthodontic treatment for elimination of dental compensations followed by combined maxillomandibular surgery with rigid internal fixation. Lateral cephalograms from each patient, obtained in the natural head position before surgery, immediately after surgery, and at 6-month follow-up, were retrieved from the files of the Pontifical Catholic University of Rio Grande do Sul outpatient Oral and Maxillofacial Surgery clinic and compared. Comparison of craniometric landmark measurements showed that the precision of mandibular setback was compromised in the horizontal plane, with a mean mandibular relapse of 37.75% at point B and 45.85% at point Pg. Improved intercuspation and adaptation of the musculature to the new position of the jaws after orthognathic surgery lead to counterclockwise rotation of the mandible, ultimately displacing the mandible more anteriorly than desired.
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.
