description Background: Diseases of the orbit represent a surgical challenge, particularly those compromising the orbital apex. Optimal surgical access should provide the best possible exposure, allowing to identify certain key anatomical structures, called landmarks. Objective: Describe the endoscopic anatomy of the structural unit formed by the Inferior Orbital Fissure (IOF) and the Müller’s muscle (MM) at the orbital apex (OA), thus generating a new endoscopic anatomical landmark. Materials and methods: A bone-descriptive analysis of the IOF in dry craniums, was followed by dissection and endoscopic study of six heads (twelve sides), colored and fixed in formaldehyde. In ten dry craniums (twenty sides), distances and angles of OA foramina were measured (optic foramen [OF] and foramen rotundum [FR]). Statistical analysis was performed with SPSS 17.0 statistical software (SPSS, Inc. Chicago, IL). Results: The structural unit IOF-MM was identified in all endoscopic dissections, verifying its intimate relationship with the OA. From the morpho-metric standpoint, OF and FR were found at an average distance of 65.19 mm and 60.16 mm, respectively. The average angle of the OF was 13.32 degrees, whereas the one for FR was 19.31 degrees. We found a significant correlation between OF and FR only on the left side (left hemi-crane) (Kendall Tau b 0.69, p=0.006). There were no anatomical or morphological differences between both sides. Conclusion: The unit IOF-MM is a constant anatomical landmark, useful and safe under endoscopic technique, which allows the recognition of the OA and its contiguous areas.

Antecedentes: Las enfermedades que afectan la órbita representan un desafío quirúrgico, en particular las que comprometen el ápex orbitario. Una vía óptima de acceso quirúrgico proporciona la mejor exposición permitiendo identificar ciertas estructuras anatómicas claves llamadas reparos anatómicos. Objetivo: Describir la anatomía endoscópica de la unidad estructural Fisura Orbitaria Inferior / Músculo de Müller a nivel del ápex orbitario generando así un nuevo reparo anatómico endoscópico. Material y método: Análisis descriptivo óseo de la fisura orbitaria inferior (FOI) en cráneos secos, disección y estudio bajo técnica endoscópica de 6 cabezas fijadas en formol y coloreadas; finalmente se tomaron distancias y ángulos a forámenes relacionados con el ápex orbitario a 10 cráneos secos. El análisis estadístico se realizó con el programa estadístico SPSS 17,0 (SPSS, Inc., Chicago, IL). Resultado: En todas las disecciones endoscópicas se pudo identificar la unidad fisura orbitaria inferior-músculo de Müller y también verificar su íntima relación con el ápex orbitario. Morfométricamente el foramen óptico y el foramen redondo mayor están a una distancia promedio de 65.19mm y 60.16mm respectivamente. Los ángulos promedio del FO fue de 13.32 grados y del FRM de19.31 grados. Hallamos correlación significativa entre CO. y el FRM sólo en el hemicráneo izquierdo, (Tau b de Kendall 0.69, P=0.006). No se encontraron diferencias anatómicas (o morfológicas) significativas entre lados. Conclusión: bajo técnica endoscópica la unidad Fisura Orbitaria Inferior-Músculo de Müller (FOI-MM) es un reparo anatómico constante, útil y seguro que permite el reconocimiento del ápex orbitario y sus áreas contiguas.  Universidad Nacional Cba.
