Gamma knife radiosurgery for trigeminal neuralgia: is anterior selective targeting a reasonable alternative?

Key Points

• This research evaluates the effectiveness of anterior selective targeting (AST) for pain relief in trigeminal neuralgia patients.
• Examined selected trigeminal neuralgia patients without V1 involvement
• Compared outcomes of AST to DREZ after 12 months
• Measured beam-on time for each intervention
• AST provided effective pain control comparable to DREZ
• AST demonstrated shorter beam-on time in the selected patients
• Recommendations suggest AST as a viable option for initial or repeat gamma knife surgery
