“…Knight and North (1961) classified fractures into 6 groups and 4 subdivisions based on plain radiographic films. The system allows for easy evaluation and is clinically useful, but cannot be used to evaluate bone displacement in 3-dimensions.…”

“…And traditionally, Knight and North (1961), Larsen and Thomsen (1978), Kristensen and Tveterås (1986) and Zingg et al (1992) classified the zygomatic fractures based on examination of plain radiographic films or intraoperative findings. However, regardless of the group of the classifications, Rohrich et al (1992) and Convington et al (1994) mentioned that 3-point fixation with steel wire is performed in almost all cases of zygomatic fractures.…”

The researchers establish a new classification system for zygomatic fractures based on computed tomography and mechanism of injury, which could be used to inform treatment options.Patients treated for isolated zygomatic fracture at the Keio University Hospital between 2004 and 2011 were recruited for this study. The cases were classified into 4 types based on the fracture pattern of the zygomaticofrontal suture and inferior orbital rim.In total, 113 patients aged 16 to 82 years (mean age (SD) = 39.8 (17.0) years), including 74 men and 39 women, were analyzed. Overall, 54 patients had shear fractures and 59 patients had greenstick type fractures. In both shear and greenstick fractures, the ratio of medial type fractures was significantly higher than that of lateral type fractures (p < 0.001). Furthermore, the number of shear type fractures in those <20 years old was lower than that in other age groups (p < 0.05).In conclusion, this classification is an epoch-making classification based on the mechanism of facial injury, and may be used to inform treatment options to achieve optimal biomechanical stability.

“…Our CT scan revealed a tripod fracture of the left zygoma, classified in Knight & North's classification as group V [9], and a fracture of the left mandibular angle. Although the zygomatic bone was severely displaced, there was no orbital blow-out fracture and the mandibular angle was undisplaced ( Figure 3).…”

“…No caso exposto, o tratamento proposto foi realizado com redução aberta para melhor redução e estabilização da fratura do grupo IV segundo classificação de Knight e North de 1961 11 . A fixação interna rígida, que consiste em uma fixação através da utilização de placas e parafusos em fraturas do complexo zigomático podem ser feitas em pilar zigomático, sutura frontozigomática, pilares caninos e margem infraorbitária.…”

ResumoDevido a sua localização projetada na face, o complexo zigomaticomaxilar é uma região comumente acometida por traumas e injúrias, fraturando-se pela ação direta de forças, ocasionando uma mudança em sua projeção anteroposterior e laterolateral. As etiologias dos traumas que podem provocar uma fratura nessa região podem variar, sendo em grande parte as agressões físicas, acidentes de trânsito e esportivos. Objetivo: apresentar um relato de caso clínico de um paciente de 17 anos, gênero masculino, sem histórico de alergias ou comorbidades, vítima de acidente esportivo. Ao exame físico extrabucal foi possível observar edema em hemiface esquerda, degrau palpável em sutura frontozigomática e equimose periorbitária esquerda. Ao exame intrabucal observou-se fratura de pilar zigomático com oclusão mantida. O tratamento cirúrgico foi realizado através da fixação com miniplaca e parafusos do sistema 1.5 em sutura frontozigomática e miniplaca 2.0 em "L" no pilar zigomático. Conclusão: Com base no exposto, a fixação interna rígida com uso de miniplacas em sutura frontozigomática e pilar zigomático mostrou-se efetiva para restabelecer o adequado posicionamento do complexo zigomaticomaxilar, devolvendo também melhores condições funcionais, estéticas e psicológicas ao paciente. Descritores: Fraturas maxilares; Fraturas Zigomáticas; Traumatismos Faciais. AbstractDue to its projected location on the face, the zygomaticomaxillary complex is a region commonly affected by trauma and injuries, fracturing by the direct action of forces, causing a change in its anteroposterior and laterolateral projection. The etiologies of trauma that can cause a fracture in this region can vary, being largely physical aggressions, traffic accidents and sports. Objective: to present a clinical case report of a 17-year-old male patient, with no history of allergies or comorbidities, a victim of a sports accident. On the extra-buccal physical examination it was possible to observe left-sided hemifacial edema, a palpable step-off at the zygomaticofrontal suture and left-side periorbital bruise. Intrabuccal examination showed a zygomatic pillar fracture with maintained occlusion. Surgical treatment was performed by means of miniplate and screws of system 1.5 in zygomaticofrontal suture and mini-plate 2.0 in "L" in the zygomatic pillar. Conclusion: on the basis of the above, the intrafixation with the use of mini-plates in zygomaticofrontal suture and zygomatic pillar was effective in restoring the proper positioning of the zygomaticomaxillary complex, also restoring better functional, aesthetic and psychological conditions to the patient.
