Abstract：Objiective To investigate the value of cross-sectional area parameters of the cerebellopontine angle (CPA) cistern for predicting primary trigeminal neuralgia (PTN) and evaluating prognosis of microvascular decompression (MVD). Methods The clinical data of 54 patients with PTN (PTN group) undergoing MVD were analyzed retrospectively. The cross-sectional area and the area deviation of the CPA cistern were measured. There were 21 healthy volunteer (control group) as comparison. The relevant factors maybe affecting therapy in PTN were analyzed. Results The cross-sectional area of bilateral CPA cistern was not statistically significant in control group (P ＞ 0.05). In PTN group, the cross-sectional area of CPA cistern in the affected side was smaller than that in the healthy side and there was a significant statistical difference (P =0.002). The area deviation of CPA cistern in PTN group was smaller than that in control group and the difference was statistically significant (P ＜ 0.001). According to the efficacy of MVD, 54 PTN patients were divided into recurrence group (n =15) and non-recurrence group (n =39). The area deviation of CPA cistern in recurrence group was smaller than that in non-recurrence group and there was statistical significance (P =0.034). The PTN of left side was more likely to relapse than right side with statistical significance (P =0.018). Conclusions Smaller cross-sectional area and area deviation of CPA cistern are the predictive index of PTN. The MVD treatment is worse in PTN patients with smaller area deviation of CPA cistern. PTN is more likely to recur on the left side than on the right.
