Summary

This study introduces an algorithm to personalize awake craniotomy for brain tumor surgery, improving patient safety and preserving language function. The protocol tailors neurosurgical and anesthetic approaches based on individual risk and functional data.

Area of Science:

  • Neurosurgery
  • Anesthesiology
  • Neurophysiology

Background:

  • Intra-operative neurophysiological language mapping is standard for language cortex tumor resections.
  • Awake craniotomy presents risks and significant patient stress.
  • Tailoring surgical and anesthetic techniques to individual patients is crucial.

Purpose of the Study:

  • To establish an algorithm for individualizing neurosurgical and anesthetic techniques in awake craniotomy.
  • To optimize patient safety and functional outcomes during language cortex tumor surgery.

Main Methods:

  • 25 patients underwent awake craniotomy with intra-operative language mapping.
  • Functional MRI and cortical mapping data informed neuronavigation.
  • Tumor resection was performed under conscious sedation or general anesthesia based on risk assessment.

Main Results:

  • Patients were classified into four groups (BACC I-IV) based on functional data and operative risk.
  • Group BACC III (adequate data, increased risk) showed fewer adverse events with general anesthesia and functional navigation.
  • No permanent language function deterioration was observed.

Conclusions:

  • A multimodal protocol for awake craniotomy enables tailored tumor resection.
  • Functional neuronavigation under general anesthesia is beneficial for selected patients.
  • The algorithm effectively preserves function and reduces operative risk in language cortex surgeries.
