Comparison of the recurrence rate and recurrence-free survival time of patients with primary trigeminal neuralgia after operation between the PSR and MVD groups.
| Time point | MVD group (n=52) | PSR group (n=65) | ||
|---|---|---|---|---|
| I~IIIb | IV + V | I~IIIb | IV + V | |
| 6 months after operation | 50 (96.15) | 2 (3.85) | 60 (92.31) | 5 (7.69) |
| 12 months after operation | 49 (94.23) | 3 (5.77) | 57 (87.69) | 8 (12.31) |
| 24 months after operation | 47 (90.38) | 5 (9.62) | 49 (72.31) | 16 (27.69) |
| 36 months after operation | 44 (84.62) | 8 (15.38) | 43 (67.69) | 21 (32.31) |
I~IIIb, no reoccurrence; IV + V, reoccurrence; MVD, micro-vascular decompression; PSR, Partial Sensory Rhizotomy.
