%X Introducci車n: El seno esfenoidal presenta una relaci車n 赤ntima con diversas estructuras nobles de la base del cr芍neo. Objetivo: El objetivo de este estudio es describir la anatom赤a del seno esfenoidal utilizando la v赤a endosc車pica transnasal directa. Material y m谷todo: M谷dicos del Servicio de Otorrinolaringolog赤a del Hospital Barros Luco Trudeau realizaron las disecciones en cad芍veres del Servicio de Anatom赤a Patol車gica de la misma instituci車n. Se realizaron diversas mediciones de la fosa nasa en relaci車n al seno esfenoidal y se observaron la caracter赤sticas del seno esfenoidal en relaci車n a las estructuras neurovasculares que se proyectan en la pared. Resultados: Se estudiaron veinte cad芍veres con una mediana de edad de 70 a os. El 65% eran de sexo masculino. El 65% present車 configuraci車n selar. El 60% de los senos presentaron m迆ltiples septos. El ostium esfenoidal se encontr車 en la mayor赤a de los casos medial al cornete superior. Se apreci車 proyecci車n en el seno del 80%% de car車tidas (con 5%% de dehiscencias), 85%% de nervios 車pticos, 40%% de nervios maxilares, 15%% de nervios vidianos, y 15%% de celdas de Onodi. Conclusiones: El seno esfenoidal es una estructura compleja relacionada con estructuras nobles que se proyectan al interior de 谷ste, por lo que su conocimiento acabado es fundamental para su abordaje quir迆rgico y de la base de cr芍neo. Introduction: The sphenoidal sinus has an intimate relationship with critical structures and their exposure in the sinus walls depend on the pneumatization degree. Aim: The aim of this study is to describe the anatomy of the sphenoid sinus using direct transnasal endoscopic approach on a sample of adult corpses. Material and method: We performed endoscopic dissection of twenty corpses of the Pathology Department of the Hospital Barros Luco Trudeau. Various measurements were made from the nostrils. A description of the neuro-vascular structures projected into the sinus was performed. Results: The median age was 70 years. 65% were male. 65% of the sinuses had sellar configuration. 60%% of the sinuses had multiple septa. The sphenoid ostium was in most cases located medial to the superior concha. 80% of the carotid arteries were projected into the sinuses (5(0)% were dehiscent). 85%% of the optic nerves, 40%% of maxillary nerves, and 15%% of vidian nerves were observed in the sinuses. Onodi cells were found in 15% of the sinuses. Conclusions: The sphenoid sinus is a complex structure adjacent to delicate structures. It is essential to be aware of these structures and their anatomical variations to perform a safe sur
