CyberKnife® frameless radiosurgery offers the least invasive technique for certain functional disorders with clinical outcomes comparable to frame-based radiosurgery.
Romanelli et al. Image-Guided Robotic Radiosurgery for Trigeminal Neuralgia. Neurosurgery. 2017 Dec 23.
138 trigeminal neuralgia patients treated to median dose 75 Gy and median target length 5.7 mm
Actuarial pain control rate at 6, 12, 24, and 36 months
were 93.5%, 85.8%, 79.7%, and 76% respectively
Pain relief was achieved in 93.5% of patients
Monthly tests demonstrated a median Total Treatment Error (TTE) of 0.30 ± 0.12 mm
Enabling Better Patient Outcomes
Robotic Precision
MITIGATING SIDE EFFECTS
CyberKnife robotic delivery allows for multiple beams of radiation for excellent dose distribution, reduced margins and minimized dose to radiosensitive structures to reduce the risk of side effects.
Frameless Delivery
INCREASING COMFORT & CONVENIENCE
Frameless delivery allows convenient treatment in more than one session — without requiring constrictive patient immobilization techniques.
