A new endoscopic transethmoid approach for pituitary surgery offers enhanced exposure and simplified tumor resection. This technique provides a safe, bimanual procedure with low operative morbidity for pituitary and skull base tumors.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Endoscopic Skull Base Surgery

Background:

  • Pituitary surgery traditionally involves various approaches with specific limitations.
  • Endoscopic techniques are increasingly utilized for minimally invasive cranial procedures.

Purpose of the Study:

  • To describe and evaluate a novel endoscopic transethmoid approach for pituitary surgery.
  • To compare this new method with existing surgical techniques for pituitary tumor removal.

Main Methods:

  • An image-guided endoscopic transethmoid procedure was performed on eleven patients for pituitary tumor removal.
  • Key metrics documented included ease of approach, tumor resection, surgical field exposure, and operative complications.

Main Results:

  • The endoscopic ethmoidectomy approach demonstrated enhanced visualization and facilitated tumor resection.
  • A bimanual technique using separate nostrils for the endoscope and instruments simplified the procedure and improved maneuverability.
  • The pilot study reported low operative morbidity with no significant complications.

Conclusions:

  • This endoscopic transethmoid approach provides generous operative exposure and safe maneuverability for pituitary surgery.
  • The technique is familiar to otolaryngologists and applicable to other skull base tumors, including potential revision surgeries.
