Summary
Awake craniotomy offers a safe approach for brain tumor resection near critical areas. This neurosurgery technique maximizes tumor removal while preserving patient neurological function, especially for low-grade gliomas.
Area of Science:
- Neurosurgery
- Neuro-oncology
- Neurophysiology
Background:
- Awake neurosurgery is a valuable technique for brain tumors located near eloquent brain areas.
- Low-grade gliomas often require precise surgical strategies to balance maximal resection with functional preservation.
Purpose of the Study:
- To evaluate the safety and efficacy of awake craniotomy for brain tumor resection.
- To assess the impact of awake surgery on maximizing tumor resection and preserving neurological function.
Main Methods:
- Performed 40 primary and 8 residual awake craniotomies.
- Utilized intraoperative neurophysiological monitoring, including direct cortical stimulation and motor evoked potentials.
- Assessed language and motor function using standardized neurological testing.
Main Results:
- Complete tumor resection was achieved in 18 of 40 primary surgeries.
- Full neurological recovery was observed in 29 patients at three months post-surgery.
- Persistent neurological deficits at three months were present in 11 patients, with 9 having preoperative symptoms.
Conclusions:
- Awake surgery is a safe and effective method for treating low-grade gliomas.
- Intraoperative neurophysiological methods enhance the safety and outcomes of awake craniotomy.
- Awake craniotomy improves treatment outcomes for patients with brain tumors near eloquent areas.
