ABSTRACT
BACKGROUND: Locking reconstruction plates are used in the treatment of jaw trauma and diseases if there is a need for surgical resection and to prevent pathologic fracture after tumor excision. Fixation is typically performed using an extraoral approach. METHODS: This article describes a technique for the intraoral fixation of locking reconstruction plates that uses prototyping to model the plate before the procedure as well as an implant handpiece with adapted drills for bone drilling and the insertion of screws into relatively inaccessible areas. CONCLUSION: Intraoral fixation not only prevents nerve damage and facial scarring but also minimizes the plate's risk of extraoral exposure and reduces surgical morbidity. © 2016 Wiley Periodicals, Inc.

As fraturas fronto-naso-órbito-etmoidal (FNOE) envolvem o centro superior e médio da face e são injúrias de difíceis diagnóstico e terapêutica. O diagnóstico é baseado em exames clínicos e de imagem por meio da tomografia computadorizada (TC). O tratamento das fraturas FNOE visa restaurar adequadamente a arquitetura do osso frontal, a correta distância intercantal entre as comissuras palpebrais mediais, a projeção do dorso nasal, o nivelamento do globo ocular, além da relação de drenagem do seio frontal pelo ducto frontonasal, que por muitas vezes, pode não estar patente, gerando possíveis processos patológicos. Sabe-se que a complexidade do trauma e, consequentemente, das fraturas, além do tempo de intervenção cirúrgica, repercute diretamente no resultado do tratamento funcional e estético. O avanço nas técnicas cirúrgicas, a TC, os materiais de osteossíntese atuais e a experiência coletiva dos cirurgiões, têm contribuído para a redução das sequelas resultantes das fraturas FNOE, oferecendo um resultado mais previsível. O objetivo deste estudo é reportar um tratamento de fratura FNOE, descrevendo os passos cirúrgicos realizados, discutindo suas vantagens e desvantagens e servindo de guia para cirurgiões e residentes, além de mostrar o resultado funcional e estético satisfatório...

The fronto-naso-orbital-ethmoid (FNOE) fractures involves the upper and middle portion of the face and it is injuries of difficult to diagnostic and therapeutic. The diagnosis is based on clinical exams and imaging tests by computed tomography. The treatment of FNOE fractures aims to restore properly the architecture of the frontal bone, the correct intercantal distance between the medial palpebral commissure, the projection of the nasal dorsum, the leveling of the eyeball, and the ratio of frontal sinus drainage by naso-frontal duct that by often cannot be patent, resulting in possible pathological processes. It is known that the complexity of the trauma and hence of fractures, and the time of surgery, directly affect in the outcome of the functional and aesthetic treatment. The advances in the surgical techniques, CT, current osteosynthesis materials and the collective experience of the surgeons, have helped to reduce the sequelae resulting of the FNOE fractures and providing an outcome more predictable. The aim of this study is to report a treatment of FNOE fracture describing the surgical steps performed, discussing their advantages and disadvantages, and serving as a guide for surgeons and residents, besides showing satisfactory aesthetic and functional results...
