A series of 246 patients who underwent MVD for TN were involved in the study. The classifications were based on the characteristic of pain (shocklike or constant), and the presence of MA was defined from the chart review, retrospectively. Surgical outcomes are defined as excellent, good, or poor. Immediate and long-term outcomes were compared to provide the information on recurrence and delayed relief. The relationship among the groups was investigated, and the strength was determined.
The presence of MA and the type of TN pain are significant predictors of surgical outcome (P < 0.05). MA was proved to be an independent predictor of surgical outcome and a significant predictor of existence of neurovascular compression (P < 0.05) and lower rate of recurrence (P < 0.05). No statistically significant predictors of delayed relief were detected in this study.
The presence of MA is a reliable predictor of immediate and long-term outcome after MVD for TN. Compared with the patients without MA, the incidence rate of intraoperative neurovascular compression was higher in MA-positive patients, who were more likely to achieve a better outcome and lower rate of recurrence after MVD for TN. Application of the information in this study will be helpful in patient selection of MVD for TN.
