ABSTRACT

RESUMEN El cavum de Meckel (CM) es un divertículo localizado en la fosa media adyacente al seno cavernoso. Las neoplasias de esta región son extremadamente raras y representan un desafío para el cirujano debido a las estructuras neurovasculares que se encuentran en la región. Para los tumores ubicados en esta área se han descrito diversos abordajes quirúrgicos, los cuales no logran una adecuada exposición a la porción anteromedial del CM. En la última década, se ha postulado el abordaje endoscópico endonasal extendido (AEE) como una alternativa quirúrgica para el manejo de lesiones ubicadas en esta región. Se presenta el caso de un paciente portador de un schwannoma del nervio trigémino situado en el CM derecho tratado mediante AEE.


ABSTRACT The Meckel's cave (CM) is a diverticulum located in the middle fossa adjacent to the cavernous sinus. The neoplasms of this region are extremely rare and represent a challenge for the surgeon due to the neurovascular structures that occupy and surround the parasellar region. For tumors located in this area, several surgical approaches have been described, all of which do not achieve an adequate exposure to the anteromedial portion of CM. In the last decade, the extended endonasal endoscopic approach (EEA) has been postulated as an alternative for the surgical management of tumors located in this region. We present the case of a patient with a trigeminal schwannoma located in the right CM treated by EEA.
