Throughout surgical procedure, a tiny incision is made within the cranium via which a needle is inserted and subsequently eliminated. Stomatotaxis is the time period for utilizing this process to carry out a biopsy or to deal with a medical situation.

Endoscopy, which makes use of a tiny scope to do biopsies and entry spinal fluid channels, and complex frameless stereotaxic computer-aided tumour resections are different cutting-edge surgical strategies.
