The endoscopic supraorbital translaminar approach (ESOTLA) offers a minimally invasive keyhole option for third ventricle tumors. This technique improves visualization and access, potentially reducing neurocognitive and visual deficits compared to traditional methods.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Endoscopic Techniques

Background:

  • Surgical management of third ventricle tumors presents significant challenges due to complex anatomy.
  • Traditional open microsurgical techniques may have limitations in accessing certain tumor locations.
  • The endoscopic supraorbital translaminar approach (ESOTLA) is explored as an alternative.

Observation:

  • The ESOTLA utilizes a keyhole craniotomy combined with endoscopic visualization.
  • This approach provides enhanced illumination and a wider field of view within the third ventricle.
  • It facilitates improved access to retrochiasmatic tumors and minimizes retraction of brain structures.

Findings:

  • The ESOTLA allows for reduced retraction of the frontal lobe and optic chiasm compared to microscopic approaches.

  • This reduction in retraction may decrease the risk of neurocognitive and visual deficits.
  • Complications are rare, mainly cosmetic, with potential hypothalamic or optic apparatus compromise manageable through careful dissection.
  • Implications:

    • The ESOTLA represents a promising minimally invasive alternative for third ventricle tumor resection.
    • It offers potential advantages in preserving neurological function and reducing surgical morbidity.
    • Further application and understanding of the ESOTLA can refine surgical strategies for complex intracranial lesions.
