Surgical Concept and Long-Term Outcomes of Various Case-by-Case Decompressive Techniques for Trigeminal Neuralgia Caused by the Trigeminocerebellar Artery

This study among 146 patients with TN observed 13 patients (9%) caused by TCA and confirmed the favorable long-term outcomes in 12 patients (92%) with complete resolution of symptom without recurrence. As TCA has disadvantageous anatomic structures to be separated from trigeminal nerve, to treat TN caused by TCA, contemporary standard techniques are insufficient at times and various case-by-case surgical techniques must be required.
