Summary
This summary is machine-generated.

This study identifies the optimal surgical entry point on the inferior circular insular sulcus (ICIS) for the transpterional-insula approach. Findings suggest a specific anterior point on the ICIS minimizes damage to the temporal stem during brain surgery.

Area of Science:

  • Neurosurgery
  • Neuroanatomy
  • Medical Imaging

Background:

  • The transpterional-insula approach is used for accessing brain tumors.
  • Minimizing damage to the temporal stem is crucial for patient outcomes.
  • Precise anatomical landmarks are needed to guide surgical incisions.

Purpose of the Study:

  • To measure the inferior circular insular sulcus (ICIS) and its proximity to the temporal horn.
  • To determine the optimal incision point for the transpterional-insula approach.
  • To reduce harm to the temporal stem during this surgical procedure.

Main Methods:

  • Utilized volume-rendering technique for detailed 3D anatomical visualization.
  • Measured the ICIS and the shortest distance to the temporal horn.
  • Compared measurements between cerebral hemispheres.

Main Results:

  • The one-third point on the anterior side of the ICIS was identified as the ideal penetration point.
  • No significant difference in ICIS measurements was found between the left and right hemispheres (P < 0.05).
  • Volume rendering proved to be a reliable method for insular region measurements.

Conclusions:

  • The anterior one-third point of the ICIS is recommended for surgical incision in the transpterional-insula approach.
  • This approach, guided by precise measurements, can minimize temporal stem injury.
  • Volume rendering is a valuable tool for insular lobe anatomical studies and surgical planning.
