Summary
Endoscopic endonasal surgery for skull base lesions is advancing. This study shows a novel navigation technique using laser surface scanning is safe, effective, and faster for pituitary lesion resection.
Area of Science:
- Neurosurgery
- Skull Base Surgery
- Endoscopic Surgery
Background:
- The endoscopic endonasal, transsphenoidal approach is increasingly used for skull base resections.
- Traditional neuronavigation methods often rely on adhesive-mounted fiducial registration, which can be cumbersome.
Purpose of the Study:
- To evaluate a novel surgical navigation technique using laser surface scanning for endoscopic endonasal resection of pituitary lesions.
- To compare the advantages and safety of this technique against conventional neuronavigation methods.
Main Methods:
- Sixty-three consecutive patients with pituitary lesions underwent endoscopic endonasal surgery.
- Surgical navigation was performed using BrainLAB reference headband and laser surface scanning.
- Patient head positioning was flexible, without the need for rigid fixation in a Mayfield clamp.
Main Results:
- The technique was successfully applied in all 63 patients.
- Laser surface scanning navigation offered advantages in head positioning flexibility, allowing better exposure of the clivus and anterior skull base.
- The method proved to be safe, easy-to-use, and faster than other navigation techniques.
Conclusions:
- Laser surface scanning with a reference headband provides a safe, effective, and efficient navigation method for endoscopic endonasal pituitary surgery.
- This technique overcomes limitations of traditional neuronavigation, enhancing surgical flexibility and exposure.
