    Area of Science:

    • Neurosurgery
    • Otolaryngology
    • Endoscopic Skull Base Surgery

    Background:

    • Conventional transsphenoidal approach limitations for complex cavernous sinus and suprasellar tumors.
    • Need for enhanced surgical visualization and access in challenging skull base resections.
    • Tumor resection in critical anatomical regions requires minimally invasive yet effective techniques.

    Discussion:

    • The extended transsphenoidal approach with submucosal posterior ethmoidectomy significantly expands surgical visualization superiorly and laterally.
    • This technique facilitates safer and less invasive access to difficult-to-reach tumors within the cavernous sinus and suprasellar regions.
    • The extended approach allows for improved resection of large pituitary adenomas, craniopharyngiomas, and tuberculum sellae meningiomas.

    Key Insights:

    Related Experiment Videos

    • Successful application in 14 patients with pituitary adenomas, 3 with craniopharyngiomas, and 1 with meningioma.
    • Demonstrated absence of postoperative complications, including olfactory disturbance, cranial nerve palsy, and arterial injury.
    • The extended approach provides a valuable alternative for complex skull base tumor resections.

    Outlook:

    • Potential for wider adoption in neurosurgical and skull base procedures.
    • Further research may explore long-term outcomes and applicability to other tumor types.
    • This technique represents a significant advancement in minimally invasive skull base surgery.
