| Popis: | Backgrounds Trigeminal neuralgia (TGN) is a common pain syndrome of nervous system, despite about 90% patients who were refectory to medications could free from pain after microvascular decompression (MVD), some patients did experience recurrence. Objectives The study aimed to analyze clinical characteristics of patients with recurrent TN, recurrence factors of TN, and prognosis after re-do MVD. Methods Clinical data and at least 12 months follow-up of patients with recurrent TN who underwent re-do MVD in our hospital from 2005 to 2020 were collected and analyzed. Results 14 patients with recurrent TN were enrolled eventually, adhesive arachnoid membranes were found in all patients. Teflon granuloma was found in 10 patients, new neurovascular compression (NVC) in 3 patients, and Teflon displacement in 1 patient. Pain disappeared in 12 patients and relieved in 2 patients, but 4 patients experienced facial numbness and 1 patient suffered from incision infection after re-do MVC. No serious surgery-related complications and pain recurrences were recorded. Conclusions Teflon granuloma was the most common cause of TN recurrence in current study, new NVC was also a common cause, patients with recurrent TN could get satisfactory results from re-do MVD. |
