This study presents a novel transsphenoidal supradiaphragmatic intradural approach for removing brain tumors. This technique provides a wide surgical field, enabling safe tumor removal with minimal complications.

Area of Science:

  • Neurosurgery
  • Surgical Oncology

Background:

  • The transsphenoidal approach is a minimally invasive technique for accessing the pituitary gland and surrounding structures.
  • Tumors in the suprasellar region, such as tuberculum sella meningiomas and Rathke's cleft cysts, can be challenging to access and resect.
  • Expanding the surgical corridor is crucial for improving visualization and safety during tumor removal.

Observation:

  • A modified transsphenoidal approach involving presellar bone window extension and sellar floor removal was utilized.
  • This technique allowed for intradural access to the suprasellar and pre-sellar compartments.
  • The dissection included the anterior intercavernous sinus, diaphragma sella, and arachnoid trabecula, enhancing the surgical field.

Findings:

  • Two cases, a tuberculum sella meningioma and a suprasellar Rathke's cleft cyst, were successfully resected using this approach.

Related Experiment Videos

  • The technique facilitated a wide surgical field, enabling safe and complete tumor removal.
  • No significant surgical complications were reported in these selected cases.

    • Implications:

    • This enhanced transsphenoidal approach offers a viable and safe option for resecting specific suprasellar and pre-sellar tumors.
    • It expands the utility of minimally invasive endoscopic techniques for complex intracranial pathologies.
    • Further research may validate this technique for a broader range of sellar and suprasellar lesions.
