“…Fractures of the zygomatic-orbital complex (ZOC) are highly frequent, resulting mainly from traffic accidents, physical aggression, and sports activities 1 . The surgical treatment of ZOC fractures warrants particular attention due to the complex anatomy and possible involvement of other structures of the middle third of the face 2,3 . Bone fracture reduction and fixation with titanium plates is challenging due to the restricted surgical access and the anatomy of the orbital region, which hinders the modeling process of the fixation plates 3 .…”

“…The difficulty in ensuring the same anatomic position as prior to the trauma increases the risk of esthetic and functional problems, such as enophthalmos, diplopia (double vision), limited mouth opening, and facial asymmetry 2 . It is therefore necessary to restore the anatomy as it was prior to the trauma in order to recover function and esthetics 1,4,5 .…”

“…The use of prototypes has offered benefits to craniomaxillofacial surgery, such as greater predictability and a shorter operating time due to the use of pre-molded plates, which are possible through more detailed planning 2,3 . Stereolithography (SL) is a rapid prototyping process that enables constructing three-dimensional (3D) models with a richness of details 4 .…”

“…However, this method has been used little as an aid in the reduction of fractures in the middle third of the face 5 . Among the techniques for obtaining prototypes, the mirror-image method, in which the software mirrors the non-fractured side of the face over the fractured side, is a useful tool for assisting in surgery as well as the preoperative modeling of plates 2 .…”

A correção das fraturas do complexo zigomático-orbitário são desafiadoras ao cirurgião, pela complexidade da sua anatomia e sua intima relação com múltiplos ossos da face. A prototipagem rápida pode ser um instrumento auxiliar no planejamento cirúrgico dessas fraturas com o objetivo de devolver a anatomia anterior ao trauma. Este é um estudo tomográfico de fraturas zigomático-orbitarias que foram tratadas com o auxílio de planejamento em biomodelos. Métodos: Foram incluídos seis pacientes com fratura unilateral da região zigomática-orbitaria classificados como Knight e North tipo III, IV, V e VI. A cirurgia para redução e fixação da fratura foi planejada com o auxílio de biomodelos 3D, onde a hemiface não afetada foi espelhada sobre o lado fraturado, e as placas de fixação foram pré-moldadas se baseando no lado espelhado, com o objetivo de garantir a correta projeção. A qualidade da redução cirúrgica foi avaliada usando pontos quantificáveis (parede lateral da órbita, projeção ântero-posterior do zigoma e projeção do globo ocular), que foram mensurados nas imagens tomográficas pré e pós-operatórias. Resultados: Houve ganho estatisticamente positivo na variável de projeção anteroposterior do zigoma, porém a abordagem foi mais factível com poucos pontos de fratura. Conclusão: O planejamento com biomodelos se mostrou útil na recuperação da projeção zigomática, sendo necessário levar em consideração o alto custo e o tipo de fratura na hora de optar pelo planejamento com biomodelos.

Introduction: Penetrating traumas in the orbit and intraorbital foreign bodies during pediatric age are rare and could be associated with vascular and optic nerve injuries.Clinical case: Five-year-old female patient with penetrating trauma in left orbit of 1 hour of evolution caused by a brush after accidentally tripping with a classmate while painting during art class. The patient was taken the pediatric emergency department of the Clinica Universitaria Colombia in Bogotá where she was admitted, assessed with scanographic studies and taken to surgery to remove the intraorbital foreign body.Discussion: The case of this patient was characterized by indemnity of the eyeball, central artery and vein of the retina and optic nerve, in addition to timely and interdisciplinary management that reduced the risk of complications.Conclusions: The analysis of the clinical evolution of the patient allowed identifying the key events to approach this type of cases, as well as the multiple management and prognosis alternatives according to the type and trajectory of the penetrating object.

Purpose Motorcycle-related injuries involving the eye and orbit are not well characterized, with a paucity of prospective studies focusing specifically on motorcycle-associated eye injuries nor literature reviews having been conducted on the subject. To better understand the injury types and descriptive characteristics of patients experiencing motorcycle-associated eye injuries, we sought to conduct a narrative review. Methods The research team utilized the following databases: PubMed, EMBASE, and Web of Science to query for English articles from peer-reviewed journals that provided some patient data regarding eye injury due to motorcycle or moped accidents or usage. Results A total of 65 studies were included in our qualitative synthesis. Of these studies, 40 (61.5%) were case reports, 20 retrospective case series (30.8%), and five (7.69%) were observational prospective studies. Among the 25 retrospective and prospective studies, 12 (48.0%) of these studies primarily focused on motorcycle-associated injuries. These 65 studies described a wide variety of motorcycle-associated eye injuries, including but not limited to orbital fractures and associated sequelae, foreign bodies, vitreoretinal trauma, neuro-ophthalmic trauma, corneal injuries, open globe injuries, lacerations, and globe avulsions. Conclusion The current state of the literature indicates that knowledge regarding the ocular manifestations of motorcycle accidents is limited to mostly case reports and few retrospective cohort studies focused specifically on motorcycle-associated eye injuries. However, it is evident that the types of motorcycle-associated eye injuries are legion and predominantly seen in adult males, potentially leading to severe injuries and loss of vision and blindness.

Prototyping for the treatment of late zygomatic-orbital fracture: A case report

Abstract: HighlightsPrototyping is efficient for surgical zygomatic-orbital correction.The use of preshaped titanium plates reduces operative time and improves esthetics.Prototyping provides a better outcome for the patient than conventional surgery.
