How LITT Reaches Deep Brain Tumours Through a 3-mm Hole | Functional Surgery Minute #04

Video Published 2026-07-29 Updated 2026-07-29

Topic Overview

LITT enables minimally invasive ablation of deep brain tumors through a 3-mm burr hole using real-time MRI thermal guidance, avoiding the morbidity of open craniotomy and passage through healthy brain tissue. This educational short explains the technique's mechanism, clinical outcomes, and appropriate patient selection criteria.

Key Takeaways

  • LITT accesses deep brain tumours through a 3-mm burr hole, avoiding open craniotomy and preserving healthy brain tissue
  • Real-time MRI thermography guides laser ablation, providing precise temperature monitoring during the procedure
  • Minimally invasive approach reduces surgical morbidity compared to traditional resection for deep-seated lesions
  • Technology applicable beyond tumours: also used for epilepsy focus ablation and other functional neurosurgery targets
  • Technique has defined limitations—not suitable for all deep brain pathology despite minimally invasive advantages
