Summary
Awake craniotomy with stereotactic laser guidance offers a safe approach for minimally invasive brain lesion resection. This technique, aided by functional MRI (fMRI), reduces operation time and hospital stays while minimizing neurological deficits.
Area of Science:
- Neurosurgery
- Oncology
- Medical Imaging
Background:
- Awake craniotomy enables real-time intraoperative neurological function assessment.
- Stereotactic laser guidance facilitates minimally invasive resection of brain lesions in critical areas.
Purpose of the Study:
- To evaluate the safety and efficacy of awake craniotomy with stereotactic laser guidance for brain lesion resection.
- To assess the impact of functional MRI (fMRI) in conjunction with this technique on patient outcomes.
Main Methods:
- 117 patients with intracranial tumors underwent 141 resection procedures between 2000 and 2006.
- Eloquent brain areas were identified using anatomical landmarks and/or fMRI.
- Procedures involved continuous neurological monitoring and postoperative MRI.
Main Results:
- The study included 117 patients (77 males, 40 females; mean age 52.0 years).
- Common pathologies included metastasis (70) and glioblastoma multiforme (27).
- Permanent new or worsened neurological deficits occurred in 1.4% of patients, with a 0.7% mortality rate.
Conclusions:
- Awake craniotomy with stereotactic laser guidance is a safe and effective minimally invasive surgical option.
- fMRI pre-operative planning significantly reduced postoperative neurological deficits.
- The combined approach decreased mean operation time and hospital stay.
