          Abstract

          RESUMEN Introducción: El receso epitimpánico anterior (REA) es un espacio anatómico definido en 1973 por Wigand y Trillsch. Ha recibido otros muchos nombres, como: compartimento epitimpánico anterior, receso facial anterior, receso atical anterior, epitímpano anterior, receso protimpánico, receso supratubárico y seno geniculado. Se encuentra delimitado entre el tegmen tympani por arriba; la raíz del cigoma hacia delante; el músculo tensor del tímpano y su pliegue mucoso por abajo; el nervio facial medialmente y una cresta ósea posterior, el cog o rueda dentada. Presentamos una descripción de la anatomía y desarrollo embriológico de este espacio, de los procesos patológicos que con más frecuencia lo afectan y de las vías de abordaje quirúrgico. Material y métodos: Revisión sistemática de tipo narrativo Discusión: La anatomía quirúrgica del epitímpano siempre ha resultado difícil de estudiar por la complejidad de los pliegues mucosos, bolsas y ligamentos. La alteración en la ventilación desde la trompa hacia la mastoides, favorece el desarrollo del colesteatoma. Conclusión: Hemos considerado de interés realizar esta revisión bibliográfica sobre el receso epitimpánico anterior, por su complejidad, su variabilidad anatómica, la proximidad de importantes estructuras y la frecuente invasión por el colesteatoma.

          ABSTRACT Introduction and objective: The anterior epitympanic recess (AER) is an anatomical space defined in 1973 by Wigand and Trillsch. It has received many other names, such as: anterior epitympanic compartment, anterior facial recess, anterior atical recess, anterior epitympanum, protympanic recess, supratubaric recess, and geniculate sinus. It is delimited between the tegmen tympani above; the root of the zygoma in the anterior area; the tensor tympani muscle and its mucous fold below; the facial nerve medially and inthe posterior part of the space the bony ridge, the “cog” or gear wheel. We present a description of the anatomy and embryological development of this space, of the pathological processes that most frequently affect it and different the surgical approaches. Material and methods: Systematic review of narrative type. Discussion: The surgical anatomy of the epitympanum has always been difficult to study due to the complexity of the mucous folds, bags and ligaments. The alteration in ventilation from the tube to the mastoid favors the development of cholesteatoma. Conclusion: We have considered of interest to carry out this bibliographic review on the anterior epiphympanic recess, due to its complexity, its anatomical variability, the proximity of important structures and the frequent invasion by cholesteatoma.

              The surgical anatomy of cholesteatoma.

              R Jackler (1989)
              The majority of cholesteatomas assume typical growth patterns that are dictated by their site of origin and related anatomic structures. These routes of penetration tend to develop along vestigial planes that were created during the embryogenesis of the middle ear and mastoid. Knowledge of the relevant surgical anatomy allows the surgeon to recognize and remedy pathologic changes and avoid complications.
