Abstract:
1. 1. The causes of RTN may be an offending vessel or Teflon felt effect. Further vascular compression of the trigeminal nerve can be relieved. In cases of severe adhesion caused by Teflon felt, the result is satisfactory if the fibrotic adhesion can be removed completely.
2. 2. In those patients with major recurrence of TN after MVD, radiologic examinations (e.g., CT scan and MRI) may reveal the etiology.
