title: Surgical treatment of primary trigeminal neuralgia: comparison of the effectiveness between MVD and MVD+PSR in a series of 210 patients.
abstract: OBJECTIVE
  To evaluate the effectiveness of microvascular-decompression (MVD) or     MVD+partial-sensory-rhizotomy (PSR) on the treatment of primary trigeminal     neuralgia (TN).
  
  
  METHODS
  210 TN patients were retrospectively     studied, among which there're 142 cases underwent MVD and 68 cases underwent     MVD+PSR.
  
  
  RESULTS
  In MVD group, pain vanished in 128, obviously relieved in 9,     and 137 cases were profited from MVD. In 82 cases with a follow-up over 2 years,     pain vanished in 74, pain sometime occurred in 5 which could be relieved by oral     medicine, 3 cases could not be controlled effectively by medicine. In MVD+PSR     group, pain completely vanished in 67 cases, not changed in 1 case. In 47 cases     with a follow-up over 2 years, pain sometime occurred in 2 which could be     relieved by carbamazepine, the others were completely pain-free. The short-term     pain-free rate of MVD+PSR group was obviously higher than MVD group(P <     0.05), after a follow-up over 2 years, the former was still higher than the     later, 95.7% and 90.2% respectively, without significant difference in     statistics.
  
  
  CONCLUSIONS
  MVD+PSR was obviously superior to MVD in completely     eliminating pain in short-term period after operation, however, longer pain-free     rate need even longer time to follow up. Identifying the responsible vascular     exactly and handling it reasonably were key to both groups.
