ABSTRACT

Due to the anatomical proximity between the skull and the face, maxillofacial trauma can often cause injuries to cranial structures. Among these complications are carotid-cavernous fistulas (CCF), which are rare in maxillofacial trauma, although their etiology is usually traumatic. They are described as an atypical communication between the internal carotid artery and the cavernous sinus, which can generate a sudden change in the direction and distribution of blood flow between the brain and orbit. This paper aims to report a case of craniomaxillofacial trauma in which the patient evolved with diplopia, palpebral ptosis, and ophthalmoplegia of the left eye, diagnosed as traumatic CCF. The oral and maxillofacial surgery and traumatology team of the University Hospital of Western Paraná was observed these symptoms for the first time during post-operative follow-up after one day of surgery to repair mandibular fractures of the patient in question. With the identifying the signs and symptoms, a neurosurgery was requested for assessment and management. After clinical evaluation and imaging tests, they diagnosed the condition as CCF 5 days after the mandibular fractures and the patient was referred for treatment. Surgery was performed, in the same day, to resolve the CCF with the endovascularly by embolization with micromoles. The CCF was resolved and the patient continued on outpatient follow-up, progressing without sequelae from the CCF or mandibular fractures.

ABSTRACT

For the management of cleft palate, the surgical approach has been suggested at an early stage even in childhood, varying in the number of interventions. Once the interventions are not performed at appropriate times, such as sequences that may accompany specific psychological, functional, and aesthetic effects. Since it has been indicated, temporal muscle flap is a technique with satisfactory results for a resolution of extensive clef palate in adult patients. The purpose of this paper is reporting a case of temporal muscle flap in the soft and hard palate of an adult with a reconstruction of the donor area with a titanium mesh. A 37 year old male patient with cleft lip/palate, complained of difficulty in speech, chewing, swallowing, and breathing. Clinically, it was observed oroantral communication in the region of the hard and soft palate, with a previous cheiloplasty. A temporal rotation was planned to close the fissure for the treatment. The modified coronal approach was used. Temporal muscle traction and its interposition in the palate region were performed through the tunneling technique, and mass suturing was performed. After 3 years, he presented satisfactory results, with the improvement of the quality of life, as well as the area of exposure. In conclusion, since it has been indicated, temporal muscle flap is a technique with satisfactory results for a resolution of extensive cleft palate in adult patients.

ABSTRACT

The great incidence and controversies related to the diagnosis, treatment, surgical accesses, and type of osteosynthesis materials confer an outstanding role to condylar fractures among facial fractures. Plate configurations, with diverse formats and sizes, may be used to surgically resolve condylar fractures. With the purpose of improving the advantages and minimizing the disadvantages of fixation techniques, the neck screw was developed aiming at the needed stabilization to render a correct fixation through a system of dynamic compression. This is achieved by increasing the contact between the fractured bone stumps, as well as assisting at the time of fracture reduction. The present paper aims at comparing the fixation and stability of mandibular condylar fractures using the neck screw and an overlaid "L"-shaped-4-hole-2 mm plate on the one hand, with a system in which the neck screw and the "L"-shaped plate form a single structure, having been joined by a welded point, on the other hand. The results with the neck screw are satisfactory, and, thus, it is an alternative for the reduction and fixation of fractures of the mandibular condyle, whether or not a plate is joined to the structure, provided it is correctly prescribed and with adequate surgical sequence and technique.

ABSTRACT

Introdução: muitas vezes, as limitações em técnicas ortodônticas tradicionais e o fator tempo criam barreiras para a realização de determinados tratamentos ortodônticos. Com o uso associado de novas técnicas cirúrgicas, esses tratamentos podem ser realizados de forma mais previsível, acessível e rápida, buscando maior eficiência, pois podem expandir significativamente as limitações da Ortodontia. Dois tipos principais de terapia ortodôntica cirurgicamente facilitada, cada uma com suas indicações próprias e protocolos, estão tornando-se habituais: corticotomia e osteotomia, as quais envolvem secções cirúrgicas do osso alveolar associadas à aplicação de forças. Objetivo: o presente trabalho objetivou a realização de uma revisão de literatura acerca dessas técnicas, haja vista que são alternativas eficazes, porém pouco difundidas, necessitando de maiores evidências clínicas e técnicas aprimoradas para que se tornem mais frequentes e opções reais de tratamento.

ABSTRACT

Introdução: o tratamento reabilitador através do uso de implantes osseointegrados apresenta um alto índice de sucesso. Entretanto, estudos relatam a falência de implantes devido a infecções peri-implantares. A peri-implantite é definida como um processo inflamatório que afeta os tecidos ao redor de um implante osseointegrado, resultando em perda do osso de suporte, podendo levar à perda do implante. Os tratamentos da peri-implantite consistem, principalmente, em descontaminar a superfície do implante e estabilizar a perda óssea ao seu redor e, algumas vezes, em se tentar uma nova formação óssea ao redor dessa área anteriormente infectada. Embora seja possível tratar a peri-implantite, a prevenção é o foco da terapia de suporte. Objetivo: o objetivo desse trabalho foi realizar uma revisão de literatura sobre a peri-implantite, abordando sua etiologia, diagnóstico e tratamento. Conclusão: concluiu-se que as doenças peri-implantares são possíveis complicações do tratamento com implantes dentários osseointegráveis e podem indicar risco para insucesso, mas podem, também, ser temporárias ou passíveis de tratamento.


Introduction: Dental rehabilitation using osseointegrated implants shows a high level of success. However, researches have reported implant failures due to peri-implant infections. Peri-implantitis is defined as an inflammatory, process that affects bone and soft tissues surrounding an osseointegrated implant, resulting in bone support loss, which may cause implant loss. The treatment of peri-implantitis is to decontaminate the implant surface and stabilize the bone loss around it. Sometimes the treatment consists in trying to induce new bone formation around the previously infected area. Although it is possible to treat peri-implantitis, prevention is the focus of support therapy. Objective: The aim of this study was to review articles that addressed peri-implantitis etiology, diagnosis and treatment. Conclusion: It can be concluded that peri-implant diseases, even though temporary or treatable, are possible complications of treatments with osseointegrated implants, and may represent a risk of treatment failure.

ABSTRACT

O objetivo deste estudo foi avaliar subjetivamente a imagem de perfil de tecido mole predictiva gerada por computador, em pacientes submetidos à cirurgia ortognática de avanço mandibular isolado, e, conseqüentemente, se o uso dela é aceitável para comunicação e elucidação do paciente durante o plano de tratamento, comparando os programas Dolphin Imaging e Dentofacial Planner Plus. Doze pacientes portadores de deficiência mandibular horizontal foram fotografados de perfil no préoperatório e 5 meses depois da cirurgia, no mínimo, sendo as imagens pós-operatórias confrontadas com as imagens predictivas produzidas pelos programas de imagem. Essas imagens foram analisadas por 100 cirurgiões-dentistas (50 cirurgiões buco-maxilo-faciais e 50 ortodontistas) que preencheram uma tabela de análise para cada imagem avaliada. Os resultados mostraram que: 1) O programa Dolphin Imaging foi o mais citado nos escores "excelente" e "muito bom" em todos os pontos de análise (ponta nasal, ângulo nasolabial, lábio superior, lábio inferior, região mentoniana, base mandibular, sulco lábio-mentoniano e geral), enquanto o programa Dentofacial Planner Plus foi o mais citado nos escores "regular" e "ruim"; 2) No escore "bom" houve um empate entre os dois programas nos pontos lábio superior’ e ‘lábio inferior’, sendo o programa Dentofacial Planner Plus preferido para o ponto ‘base mandibular’ e o programa Dolphin Imaging para os demais pontos de análise (ponta nasal, ângulo nasolabial, região mentoniana, sulco lábio-mentoniano e geral); e 3) Existe uma predominância média de escores "muito bom e "bom" para o programa Dolphin Imaging e de escores "bom" e "regular" para o programa Dentofacial Planner Plus. Deste modo, nas imagens de avanço mandibular, diante da metodologia empregada e dos dados obtidos no presente estudo, foi possível concluir que: os dados mostram que os dois programas foram bem aceitos na predictibilidade cirúrgica do perfil
