To the Editor

With a great interest I’ve reviewed clinical video-article “Stereotactic Biopsy and Laser Ablation of the Ganglioglioma Using a Thulium Laser”, published by Professor A. Sufianov et al. in Sechenov Medical Journal [1]. In my view, it represents the most rapidly developing area of minimally invasive epilepsy surgery today [2–4]. The combination of frameless stereotactic technology using a surgical thulium laser and intraoperative MR monitoring demonstrated in this clinical video case study can be considered one of the most successful surgical strategies for minimally invasive surgical treatment of low-grade malignant brain tumors associated with epilepsy [5][6]. The authors describe the technology of the surgical intervention step by step in an accessible manner, which is certainly of great practical value for neurosurgeons involved in the surgical treatment of epilepsy.
