Skull base surgery, brain tumor surgery, endoscopic surgery
Our group members currently perform all brain tumor surgeries using an exoscope and/or an endoscope.
Evolution of brain tumor surgery using exoscope and/or endoscope

AASNS / AANS Joint Session "Spetzler Symposium"/305
Endoscopic surgery has been developed in neurosurgical fields. Endoscopic surgery is minimally invasive with wide and bright view through a narrow surgical corridor. We started endonasal endoscopic surgery and endoscope-assisted transcranial surgery in 1990s and transcranial keyhole endoscopic surgery in 2000s. In 2010s, we developed combined transcranial and endonasal surgery, keyhole endoscopic brainstem surgery and under-water (in CSF) surgery. Now, paradigm shift is progressing from microscope to exoscope and/or endoscope. In our group, we use exoscope and/or endoscope, without microscope, for all brain tumor surgeries and other surgical procedures such as microvascular decompression. Exoscope is used for surface or shallow skull base procedures and endoscope is suitable for deep skull base or brain parenchymal procedures. We will demonstrate illustrative cases of exoscopic/endoscopic brain tumor surgeries to present evolution of the brain tumor surgery.
Endoscopic neurosurgical procedures in CSF: proposal of under-water surgery
1108 15:45-15:55
Skull Base/304A
Using an endoscope, we can have a clear surgical view in cerebrovascular fluid (CSF) to perform neurosurgical procedures. Endoscopic third ventriculostomy and tumor biopsy are performed in CSF. During cylinder endoscopic surgeries such as removal of hematoma or parenchymal tumors, we fill the surgical corridor with CSF to expand the cavity and confirm the hemostasis. For brain, circumstances in CSF is physiological. Then, we expand the endoscopic procedures in CSF and propose under-water surgery. We removed a choroid plexus papilloma in newborn baby in CSF to prevent brain collapse. In elderly patients, we selected epiarachnoid tumor debulking and under-water surgery to keep brain intact in CSF. We performed main part of micro-vascular decompression procedures in CSF. Under-water surgery could be the least invasive to keep the brain in physiological condition, especially for newborn or elderly patients.
