    Advantages of the upper eyelid approach with lateral canthotomy in the resolution of complex fronto-orbito-zygomatic fractures: bibliographic review of conventional approaches and a case report
    (2025) Tapia, Pedro; Díaz, Fernanda; Zeballos, Jessica; Díaz, Sofía; Jollán, Florencia; Ossandón-Zúñiga, Benjamín
    This study presents a modified upper eyelid approach incorporating a lateral canthotomy to improve surgical access in complex fronto-orbital fractures. A 69-year-old male patient with no comorbidities was admitted to the regional hospital of Rancagua with a left fronto-orbital-zygomatic fracture. Surgery was performed under general anesthesia using an upper eyelid incision combined with a lateral canthotomy to enhance exposure of the fracture site. Reduction and osteosynthesis of the lateral orbital wall and part of the frontal bone were successfully achieved without complications. The modified approach provided wide and direct access to the affected areas, particularly beneficial in cases with comminuted fractures requiring the placement of multiple osteosynthesis elements. The lateral canthotomy significantly expanded the surgical field, facilitating accurate reconstruction. Additionally, the eyelid incision, placed along the natural palpebral crease, offered excellent aesthetic results with a nearly imperceptible scar. This technique proves to be a valuable option for the management of complex fronto-orbital injuries, combining effective exposure with favorable cosmetic outcomes. It is especially useful in extended fractures where optimal visualization is critical for successful repair. The upper eyelid approach with lateral canthotomy thus stands out as a reliable and aesthetically conscious alternative for orbital fracture surgery.

    Análisis de las ventajas y desventajas en la Técnica Box para reconstrucción vertical de los maxilares atróficos, reporte de 4 casos
    (2024) Tapia, Pedro; Arrúe, Pablo; Guerrero, Maria; Vargas, Javier
    La reabsorción ósea vertical de los maxilares se ha transformado en un problema al momento de planificar la rehabilitación mediante implantes. Actualmente el uso de implantes de corta longitud provee de resultados aceptables a largo plazo, principalmente en defectos leves o medianos. El problema surge cuando existen defectos óseos verticales severos. Si bien el Gold estándar para las reconstrucciones mediante injertos son los bloques autólogos y la forma más predecible de ganancia ósea vertical es la distracción osteogénica, hoy en día aparecen alternativas terapéuticas, como la técnica box, que combinan elementos aloplásticos reabsorbibles con injertos de hueso homólogo. El propósito de este trabajo es presentar la experiencia de 4 casos clínicos que nos permiten evidenciar ventajas y desventajas del uso de las técnica box para reconstrucción de maxilares atróficos. Vertical bone resorption of the jaws has become a problem when planning reconstruction and rehabilitation using implants. Currently, it has been shown that the use of shortlength implants provides acceptable long-term results, mainly in light or medium defects. The problem arises in cases with severe bone defects. Autologous blocks are the gold standard for graft reconstructions and distraction osteogenesis is the most predictable form of vertical bone gain. However many therapeutic alternatives exist today, such as the box technique, which combine resorbable alloplastic elements with homologous bone grafts. The aim of this work is to present the experience of 4 clinical cases that allow us to demonstrate the advantages and disadvantages of the use of box techniques for the reconstruction of atrophic jaws.
