Attendee Question from 9th International Novalis Circle Congress.
Section: Primary Brain Tumors - Debate - SRS vs SRT for Acoustics
Panel: Juilian Biau, Isaac Yang
Can you please comment of whether or not a margin is needed for acoustic neuroma SRS? 0mm? 1mm? 2mm?

We look forward to receiving and sharing your anonymized patient cases to be discussed with an extended network of experts in the field of SRS & SBRT.
Dear Colleagues
A 52 yo lady has a progression of residual disease after partial resection 5 months ago of a grade II meningioma of the falx. Unfortunately, at that time the patient did not accept treatment.
I would propose irradiating with FSRT the whole cavity and boosting with SRT the macroscopic disease. Would you share this opinion?
Would you go for further surgery?
The patient already reported partial lower limb palsy after the first operation
Thank a lot for your kind help
Isaac Yang, MD, Neurosurgeon at the University of California Los Angeles Health discusses the role of surgical planning for vestibular schwannoma surgery. He begins by candidly telling the story of his “fifteen years of failures” in the study of the treatment of acoustic neuroma, beginning with hearing and facial nerve function preservation. He then shares the outcomes from several studies to demonstrate these “failures” and what he learned over time about the extent of resection of these types of tumors, specifically in relation to Brainlab Adaptive Hybrid Surgery software. He ends his talk with an in depth discussion about how machine learning and big data will work to inform all types of treatments in the future.
Ausaf Bari, MD, Neurosurgeon at UCLA Medical Center discusses fibertracking and its use in stereotactic radiosurgery (SRS) as well as cranial nerve imaging that has been done at his institution. He addresses the need in medical imaging for patient-specific connectivity information and outlines the use of connectivity-based imaging using diffusion tensor imaging and tractography to delineate nerve fibers, such as the trigeminal nerve and optic pathway, for targeting. With the support of case examples, he then delves into applying this principle to radiosurgical thalamotomies and demonstrates how connectivity impacts efficacy.
