Dr. Ramesh Doddamani Podcast

This video showcases the operative technique and critical nuances of trans-sylvian resection for a giant left insular glioma using microsurgical principles and advanced anatomical dissection.

Insular gliomas present significant surgical challenges due to their deep location adjacent to critical functional and vascular structures, including the middle cerebral artery (MCA) branches, lenticulostriate vessels, and eloquent cortex. The trans-sylvian approach provides direct access to the insula while preserving cortical and subcortical pathways.

The video highlights:

🔹 Preoperative planning with functional imaging and tractography
🔹 Patient positioning and operative setup
🔹 Sylvian fissure dissection and wide opening
🔹 Identification and protection of MCA branches and lenticulostriate arteries
🔹 Ultrasonic aspiration and tumor debulking techniques
🔹 Subpial dissection preserving corticospinal and language pathways
🔹 Hemostasis and closure

Emphasis is placed on microsurgical anatomy, step-by-step dissection, and strategies to minimize complications such as vascular injury, postoperative motor or language deficits, and ischemia.

Trans-sylvian resection of insular gliomas requires meticulous technique, thorough knowledge of regional anatomy, and careful handling of neurovascular structures. This video serves as a detailed educational resource for neuro-oncology surgeons and trainees seeking to refine their approach to complex insular tumors.
