Abstract

Transpatial skull base lesions involving the infratemporal fossa (ITF) are challenging due to the complex neurovascular structures of the region. Open approaches have traditionally been utilized to access these spaces. We present a 55-year-old woman presented with a mesenchymal mass involving the left ITF and masticator space. A combined endoscopic endonasal transpterygoid approach was performed followed by an endoscopic transoral-transmandibular corridor to access and resect the tumor. The post-operative course was unremarkable with no recurrence during her follow-up. Combined endoscopic approaches for transpatial tumor resection offered sufficient exposure to access safely each space.

Resumen

Las lesiones de la base craneal con una distribución transespacial e involucrando la fosa infratemporal (ITF) representan un desafío debido a las complejas estructuras neurovasculares de dicha región. Los abordajes abiertos han sido empleados tradicionalmente para acceder a estas regiones. Presentamos el caso de una mujer de 55 años que consultó por una lesión mesenquimal localizada en la ITF izquierda y en el espacio masticatorio. Se realizó un abordaje combinado endoscópico transpterigoideo endonasal seguido de un abordaje endoscópico transoral-transmandibular para acceder y resecar el tumor. El curso postoperatorio fue anodino, y no ha presentado recidiva con 21 meses de seguimiento. Los abordajes endoscópicos combinados para la resección de lesiones tumorales, con una distribución transespacial involucrando la ITF, ofrecen una exposición suficiente para acceder de forma segura a cada espacio.
