Abstract：Objective To explore and summarize the offending lesions of primary trigeminal neuralgia,in order to im-prove the pertinence and accuracy of surgery and achieve sufficient decompression of trigeminal nerve. Methods Ninety-one cases were diagnosed as primary trigeminal neuralgia before surgery,and 86 cases received planned microvascular de-compression,of which 85 cases were verified as primary trigeminal neuralgia during surgery. According to surgical find-ings,the offending lesions of primary trigeminal neuralgia were identified and analyzed. Results Of the 85 cases with pri-mary trigeminal neuralgia undergoing surgery,60 cases were found with only 1 offending vessel (70. 6％,including 3 cases with obvious arachnoid membrane adhesion),21 cases with 2 or more offending vessels (24. 7％),and 4 cases were found with no offending vessel (4. 7％,including 1 case with obvious arachnoid membrane adhesion). Of all patients receiving surgery,4 cases (4. 7％)were found with arachnoid membrane adhesion,including 3 cases accompanied with artery com-pression and 1 case with no obvious offending vessel. Conclusions For primary trigeminal neuralgia,besides solely one vessel,the offending lesions include two or more vessels,obvious arachnoid membrane adhesion and others. During the op-eration of microvascular decompression,all possible offending lesions should be identified to achieve sufficient decompres-sion of trigeminal nerve.
