Summary

The endonasal endoscopic transsphenoidal approach offers faster recovery for pituitary tumor treatment. This minimally invasive technique provides excellent visualization, potentially improving tumor resection and preserving pituitary function.

Area of Science:

  • Neurosurgery
  • Endocrinology
  • Otolaryngology

Background:

  • Developed an endonasal endoscopic transsphenoidal technique for pituitary tumor treatment.
  • Initial four patients underwent sublabial, transseptal approach with endoscope and microscope.
  • Subsequent 11 patients had endonasal endoscopic surgery without retractor or speculum.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of the endonasal endoscopic transsphenoidal approach for pituitary tumor management.
  • To compare the minimally invasive technique with traditional surgical methods.

Main Methods:

  • Retrospective analysis of 15 patients (9 female, 6 male; age 17-88) with various pituitary tumors.
  • Tumor types included microadenomas, macroadenomas with and without suprasellar extension, invasive macroadenomas, and metastatic adenocarcinoma.

  • Surgical approach was endonasal endoscopic transsphenoidal.

    • Main Results:

    • Thirteen patients with pituitary adenomas achieved symptom resolution postoperatively.
    • One patient with recurrent prolactinoma had partial response and underwent radiosurgery.
    • One patient developed a cerebrospinal fluid (CSF) leak, managed successfully with endoscopic fat graft packing.

    Conclusions:

    • Endonasal endoscopic transsphenoidal approach allows faster postoperative recovery by avoiding traditional incisions and nasal packing.
    • Offers a panoramic view, enhanced illumination, and magnification for better visualization of sellar/suprasellar structures.
    • Potential for more complete tumor resection, pituitary function preservation, and reduced neurovascular injury.
