Factors Affecting Long-Term Pain Control After Gamma Knife Radiosurgery in Secondary Tumor-Related Trigeminal Neuralgia
GKRS is effective among patients with secondary tumor-related TN, with complete pain relief in 38.8% of patients and adequate pain relief in 47.4%. The most frequent complication is facial hypesthesia, affecting 8.3% of patients. Age ≥50 years and decreased or stable tumor volume significantly predict BNI 1-3 pain relief at the latest follow-up. Although pain relief is linked to long-term tumor control, it is not the sole factor at play.
